Hello, everyone.<\/p>\n

This is Enta.<\/p>\n

This is a continuation of the previous post.<\/p>\n

Construction Methods for Technical Intern Trainees (Part 1): Slope Cleaning Work<\/a><\/p>\n

Construction Methods for Technical Intern Trainees (Part 2): Lath Installation<\/a><\/p>\n

\"Framework<\/p>\n

This is the spray-applied formwork method\u2014the true hallmark of a slope construction specialist.<\/p>\n

What on earth is the \"spray-applied formwork method\"?!<\/p>\n

 <\/p>\n

I get the feeling that not many interns really understand this.<\/p>\n

Come to think of it, maybe Japanese people are the same? lol<\/p>\n

I've written this in a detailed yet simple way.<\/p>\n

If you take a moment to understand this and put it into practice, something might just change ^^<\/p>\n

\u25a0 Performance, Functions, and Mechanisms of Spray-Applied Foam Insulation<\/h2>\n

[Structure and Mechanism of Action]<\/h3>\n
    \n
  • \n

    Construct a lattice-shaped reinforced concrete \"slope frame\" on the slope<\/p>\n<\/li>\n

  • \n

    Inside the legal framework,Place the rebar and fill the cavity with sprayed mortar<\/strong>do<\/p>\n<\/li>\n

  • \n

    The legal framework is structured to encircle the perimeter of the mountain.<\/p>\n<\/li>\n

  • \n

    Structures in Direct Contact with the Ground Surface<\/strong>So, secure the topsoil on the slope across its entire surface<\/p>\n<\/li>\n

  • \n

    Intersection of Legal Frameworks<\/strong>or the vertical and horizontal frames are respectivelyDistribute and Transfer Loads<\/strong>do<\/p>\n<\/li>\n

  • The anchors installed at the intersections of the vertical frames and on the horizontal frames are anti-slip anchors.<\/li>\n<\/ul>\n
    \n

    [Performance and Features]<\/h3>\n
      \n
    • \n

      Preventing Surface Soil Slippage<\/strong>: Preventing shallow surface landslides (shallow landslides)<\/p>\n<\/li>\n

    • \n

      Surface Protection Function<\/strong>: Protects the rock mass from surface erosion and scouring caused by wind and rain<\/p>\n<\/li>\n

    • \n

      Equal Constraint<\/strong>: Dividing the slope into a grid pattern helps prevent localized swelling and collapse of the surface<\/p>\n<\/li>\n

    • \n

      Versatility in Construction<\/strong>: Can be applied to rock formations and weathered soil of moderate hardness or lower<\/p>\n<\/li>\n

    • \n

      Wastewater Treatment Capabilities (Minimum Required)<\/strong>: By planting greenery within the frame (open-type), water is drained<\/p>\n<\/li>\n

    • \n

      Structural Continuity<\/strong>: The continuous, monolithic structure distributes the load over a wide area (supporting it as a whole)<\/p>\n<\/li>\n<\/ul>\n

      \n

      [Note: The \u201cLimits\u201d of Spray-Applied Foam Insulation]<\/h3>\n
        \n
      • \n

        For deep-seated landslides and large-scale slope failures,Powerless on its own<\/strong>(Requires the use of reinforced earthwork)<\/p>\n<\/li>\n

      • \n

        As a general rule, there is no \u201creinforcement function\u201d that directly stabilizes the slip surface underground (*Limited to surface confinement*)<\/p>\n<\/li>\n

      • \n

        In cases where the soil strength (bearing capacity) is extremely low,There is a risk that the legal framework itself could collapse or be compromised<\/strong><\/p>\n<\/li>\n

      • \n

        The drainage function is limited, andInsufficient for a fundamental solution to water pressure issues<\/strong><\/p>\n<\/li>\n<\/ul>\n

        \"Framework<\/p>\n

        To put it more simply,<\/p>\n

        The weight of the retaining wall prevents the slope from collapsing!<\/span><\/strong><\/span><\/p>\n

        That's all there is to it.<\/p>\n

        It\u2019s easier to explain to family and friends when you know what you\u2019re doing and how it\u2019s structured, isn\u2019t it? ^^<\/p>\n

         <\/p>\n

        See you later.<\/p>\n

        \u25a0 Concrete Frame Spray Construction and its performance, functionality, and Mechanism<\/h2>\n

        [Structure and Procedures]<\/h3>\n
          \n
        • On the compacted ground, a grid-shaped a concrete frame .<\/li>\n
        • Place a sheet of metal inside the frame and fill the gap with mortar .<\/li>\n
        • A structure that frames the outer part of the mountain surrounds the outer part of the frame.<\/li>\n
        • The frame is in direct contact and the surface soil .<\/li>\n
        • The frame's anchor point, the third and fourth sections are weighted form this band-shaped structure.<\/li>\n
        • Tersho Bag or Jadan Binduhar Prevents the anchor from slipping in the car is not used.<\/li>\n<\/ul>\n
          \n

          [Exhibitions and Activities]<\/h3>\n
            \n
          • It prevented the surface soil from eroding M:<\/strong> \"The mud on the surface of the path is wet,\" .<\/li>\n
          • Surface Protection:<\/strong> Protects the eyes from water and wind .<\/li>\n
          • Uniform Collection Capacity:<\/strong> The mesh structure helps keep the surface even and helps to create a uniform surface.<\/li>\n
          • General Usage Capacity:<\/strong> It can be used even on can be used.<\/li>\n
          • Drainage System:<\/strong> You can keep plants in open spaces , and it makes watering convenient.<\/li>\n
          • Structural Continuity:<\/strong> The entire structure is read out .<\/li>\n<\/ul>\n
            \n

            [Limits]<\/h3>\n
              \n
            • Whether in deep waters or shallow waters, This method alone is sufficient .<\/li>\n
            • It cannot cannot be stopped immediately.<\/li>\n
            • The frame may sink into soft ground or break.<\/li>\n
            • The water drainage capacity is limited. .<\/li>\n<\/ul>\n

              \"frame<\/p>\n

              \"The frame was resting on the ground,\" he said. It\u2019s mine!<\/span><\/strong><\/p>\n

              That\u2019s all there is to it. Once it becomes easy to understand, can be explained to others in a simple way. ^^<\/p>\n

              \u25a0 Performance, Function, and Mechanism of Concrete Frame Grout Injection Structures<\/h2>\n

              [Structure and Operating Principles]<\/h3>\n
                \n
              • Construct a reinforced concrete lattice framework on the slope.<\/li>\n
              • The frame is reinforced with steel and filled with mortar.<\/li>\n
              • The frame is constructed to enclose the outer area of the mountainside.<\/li>\n
              • The frame comes into direct contact with the ground and holds the topsoil firmly in place.<\/li>\n
              • The joints and horizontal\/vertical members help distribute and transfer loads.<\/li>\n
              • Anti-slip pads are installed at joints or crossbars.<\/li>\n<\/ul>\n
                \n

                [Functions and Benefits]<\/h3>\n
                  \n
                • Preventing topsoil erosion:<\/strong> Prevent slippage of thin soil layers.<\/li>\n
                • Surface Protection:<\/strong> Prevents erosion caused by rain and wind.<\/li>\n
                • Uniform constraint:<\/strong> The mesh structure distributes the load evenly, preventing bulging or sagging.<\/li>\n
                • Flexible installation:<\/strong> It can be applied to weak geological formations or weathered rock.<\/li>\n
                • Basic Drainage:<\/strong> You can plant the tree in a frame (open-style) to aid drainage.<\/li>\n
                • Structural connections:<\/strong> The continuous structure helps distribute the load evenly.<\/li>\n<\/ul>\n
                  \n

                  [Limit]<\/h3>\n
                    \n
                  • It is not effective for deep or large-scale landslides; other methods are needed to address them.<\/li>\n
                  • It is not possible to reinforce deep within the ground; reinforcement is limited to the surface.<\/li>\n
                  • If the ground is weak, the frame may sink or become damaged.<\/li>\n
                  • Limited drainage capacity; cannot handle high water pressure.<\/li>\n<\/ul>\n

                    \"concrete<\/p>\n

                    It is the weight of the concrete frame that helps keep the slope stable!<\/span><\/strong><\/p>\n

                    That's all there is to it. Once you understand the principle, you'll be able to explain it easily to your family and friends. ^^<\/p>\n

                    \u25a0 Construction, Use, and Mechanism of a Concrete Frame with Sprayed Mortar<\/h2>\n

                    [Structure and Mechanism]<\/h3>\n
                      \n
                    • A concrete grid was built along the edge of the grave.<\/li>\n
                    • Inside the frame, there is rebar, which is filled with mortar using a spray.<\/li>\n
                    • The frame wraps around the outside of the mountain's edge.<\/li>\n
                    • It is placed directly against the ground and prevents the topsoil from eroding.<\/li>\n
                    • The connections and the crossbeams distribute the load.<\/li>\n
                    • Anchors are installed to prevent the ground from shifting.<\/li>\n<\/ul>\n
                      \n

                      [Usage and Application]<\/h3>\n
                        \n
                      • To prevent surface scum from forming:<\/strong> Prevent shallow digging.<\/li>\n
                      • Top Protection:<\/strong> Protects against rain and wind.<\/li>\n
                      • Support for Pantay-pantay:<\/strong> Adjust the slope of the grid to prevent sudden drops.<\/li>\n
                      • Easy to install:<\/strong> It works even in poor or barren soil.<\/li>\n
                      • Basic Drainage:<\/strong> You can place a layer of soil inside the frame to allow for natural drainage.<\/li>\n
                      • Continuous structure:<\/strong> It helps distribute the weight evenly across the entire section.<\/li>\n<\/ul>\n
                        \n

                        [Limitations]<\/h3>\n
                          \n
                        • It is not sufficient for deep or large landslides; additional technology is needed.<\/li>\n
                        • It can't reach deep underground\u2014only the surface.<\/li>\n
                        • If the ground is soft, the frame may sink or become damaged.<\/li>\n
                        • Drainage capacity is limited; it is insufficient to handle high water pressure.<\/li>\n<\/ul>\n

                          \"concrete<\/p>\n

                          It's the weight of the frame that's preventing the ground from collapsing!<\/span><\/strong><\/p>\n

                          It's really that simple. It'll be easier for you to explain this to your family and friends if you understand the principle. ^^<\/p>\n

With so much free time on my hands, I started a blog. I\u2019ve been sharing my expertise on slope stabilization and answering all kinds of questions. As a result, I\u2019ve seen an increase in inquiries, questions, and orders from slope stabilization contractors, general contractors, and other major construction firms. My traffic on Ameblo grew to a reasonable level, so I decided to move on from Ameblo by acquiring my own domain in order to create a more user-friendly blog. I plan to continue sharing all my expertise openly and honestly here. I look forward to your continued support.","sameAs":["http:\/\/enta-d.co.jp\/","https:\/\/www.facebook.com\/norimenman\/","https:\/\/www.instagram.com\/enta.d\/","https:\/\/x.com\/norimenman","https:\/\/www.youtube.com\/c\/entadnorimenman"]},{"@type":"ImageObject","inLanguage":"en-US","@id":"https:\/\/norimen.net\/trainee-method-3-frame-spray\/#local-main-organization-logo","url":"https:\/\/norimen.net\/wordpress\/wp-content\/uploads\/2016\/10\/site_title_logo.png","contentUrl":"https:\/\/norimen.net\/wordpress\/wp-content\/uploads\/2016\/10\/site_title_logo.png","width":220,"height":50,"caption":"\u65b0\u30a8\u30f3\u30bf\u306e\u6cd5\u9762\u7ba1\u7406\u587e"}]}},"jetpack_likes_enabled":true,"jetpack_sharing_enabled":true,"publishpress_future_action":{"enabled":false,"date":"2026-08-20 10:04:47","action":"change-status","newStatus":"draft","terms":[],"taxonomy":"category","extraData":[]},"publishpress_future_workflow_manual_trigger":{"enabledWorkflows":[]},"jetpack_featured_media_url":"https:\/\/norimen.net\/wordpress\/wp-content\/uploads\/2025\/05\/d6a0772ae2773796c5960a9049c2ab15.jpg","_links":{"self":[{"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/posts\/54789","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/comments?post=54789"}],"version-history":[{"count":2,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/posts\/54789\/revisions"}],"predecessor-version":[{"id":64072,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/posts\/54789\/revisions\/64072"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/media\/54676"}],"wp:attachment":[{"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/media?parent=54789"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/categories?post=54789"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/tags?post=54789"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
