Anchor Installation Process: From Order Receipt to Start of Drilling

Hello, everyone.

This is Enta.

I've been in Yokohama and Tokyo for the past few days.

Big cities really are amazing, lol.

What do I mean? Well, there are just so many people.

It makes me wonder, “Are there really fewer people these days?”

It would be fine if there were just a few people walking, so,

I can't help but think, "I wish you'd become a slope engineer or an anchor specialist," lol.


But that's beside the point.

Order Received
( (purchased the book)
Review the design specifications and drawings
(Developing milk formulation plans and construction plans)
Ordering Materials
(Anchor Body · Cement)
Anchor bodies are generallyI placed the order three weeks agoPlease enter it.

On-site inspection, verification of drilling locations (verification of hole numbers)
(Drawing Data and On-Site Verification)
Water for Drilling, Plant Location, and Presence of Adjacent Residential Homes
Scaffold Worker Boarding

Confirming the Scaffolding Assembly Location
(The vertical height from the pouring position, measured at the drilling angle, marks the start of the scaffolding.)
(Ideal Ground Level for Anchor Drilling)

Based on our estimate of when the scaffolding will be completed,
Arrangements for Delivering the Drilling Rig and Crane Operations

Scaffolding Completed
(Extension of the top-most scaffold level; as-built cross-sections on the left and right; measurements and photographs for each level)

Anchor Crew Onboard

Measuring Anchor Bodies and Supervising Receiving
(Free length, fixed length, excess tension length)

Start Drilling
(Check the angle and drilling depth on the drawing)
(Digital Slant, Measuring Rod, Slime Case)
Sampling of Test Specimens for Daily Compressive Strength Testing
Checking the Tension Allowance When Under Tension
(Jack length + length of the structure under pressure)
Generally, for PC steel strand types, the length is 1.0 m to 1.2 m.

Supervision of Cement Slurry Mixing
(Test specimen, flow value, NEXCO: temperature,
(Mud Balance, Breeding, Salt Content)
(Flow cones, etc.)

Photos of the drilling, insertion, injection, and pressurization processes are
Decide in advance how often you will take photos.
(It’s safest to take photos of everything, but taking a photo of the situation about once every 10 shots is fine.)
Since the construction specifications generally state "as appropriate" or "about one location per site,"
To be specified in the construction plan.

Inspection of the finished work, including drilling length, drilling angle, and drilling diameter
(Estimating the completion date based on the number of meters drilled per day)

Book a jack rental for around the expected date.
(Please send me the jack calibration data)
Calibration refers to the process of calibrating a tension jack.

The as-built dimensions of each level of the scaffolding are measured and photographed every time a level is completed.

We dismantled the scaffolding and set up temporary scaffolding.

Prepare and submit a test plan for stress stabilization
(Created during drilling)

Confirmation Exams (All except Aptitude Tests)
Aptitude Test (3 or more subjects, or 5%)
(Review the design calculations, design drawings, etc.)
(Set up measuring instruments such as calipers)
FSC Fujiwara Industries, Inc.etc.

Observation of Qualification and Verification Tests

Dismantling of Tension Scaffolding
(Arrangements for removing the drilling machine, arranging for a truck)

Head Retouching (A few areas in the photo are sufficient)
(Baby Thunder, rebar-cutting blades, cutters, scrapers, etc.)
PC Steel Wire Cutting Speed Championship

Site Cleanup

Wrap-up
 

*For compressive strength tests, unless conducted at a public testing facility, a representative or a government official must be present.

*Even with fast-setting cement, if the bond has not set by the third day, the three-day strength is not required.
(Either 7-day intensity or 28-day intensity)

When one of our younger employees is feeling lost, they need to know exactly where they stand right now.

If you can see what lies ahead, you'll make fewer mistakes, and

You might be able to double-check and notice any discrepancies.

Well, that's it for now.
