What are the construction techniques for pre-buried and reserved cement drainage pipes?
The main material of cement pipe is our cement, which belongs to a kind of cement products. There are many cement products, cement pipes, cement boards, cement bricks, cement walls and so on.
The drainage pipe professional explained the following analysis with everyone:
The main material of cement pipe is our cement, which belongs to a kind of cement products. There are many cement products, cement pipes, cement boards, cement bricks, cement walls and so on.
I. Preparation for construction
(I) Out-of-site inspection requirements for pre-buried water-saving water-saving pipe fittings and seal templates for reserved holes
1. The reserved holes are made of ordinary steel pipes, and the surface of the steel pipes should not have obvious defects such as rust, depression and distortion. Usually when the wall thickness δ ≤ 3.5mm, the surface of the steel pipe is not allowed to have a 0.5mm deep flaw, and when the wall thickness δ ≥ 3.5mm, the depth of the flaw is not allowed to exceed 1mm.
(2) Inspection requirements for pre-buried water-saving water-saving pipe fittings
1. Purchasing the corresponding standard water-saving pipe fittings according to the plan drawing.
2. If the planned floor thickness is thicker (or the thickness of the filling layer needs to be pre-buried in place once), go to the factory to customize it.
3. When going out, check the wall thickness and standard dimensions of the pipe with a vernier caliper, and make sure that it matches the standard of the pipe material of the device before inspection and storage
(Three) the quality requirements of the seal template
1. The reserved hole template is mainly used to plug the top cover of the reserved hole mold. The template can be used with waste film covering, but it must not have holes, glue opening, severe deformation and other shortcomings.
2. The thickness of the template should not be less than 10mm.
Second, the construction process and operation points
Drain pipe hole pre
(I) Construction process
View of pre-buried water-saving water-saving pipe fittings → pre-embedded water-saving water-saving pipe fittings to seal the nozzle → civil engineering form check account → drainage pipe device positioning and marking → drainage pipe fittings fixing → quality inspection and inspection (rectification) → concrete pouring (view protection) → Drainage pipe installation.
Fixing water-saving pipe fittings according to the set point device
(Two) operation points

1. Buying, checking and inspecting the stereotypes
1) Purchasing the corresponding standard water stop according to the plan drawing.
2) If the planned floor thickness is thicker (or the thickness of the filling layer needs to be pre-buried once in place), go to the factory to customize it separately.
3) When going out, check the wall thickness and standard dimensions of the pipe fittings with a vernier caliper, and make sure that they match the standards of the pipe material of the device before inspection and storage.
2. The top nozzle of the buried water-saving pipe fitting is blocked
After checking and inspecting the water-stop festival, seal the top with tape. The tape seal must not be pasted to the touching parts of the pipe and 砼. After passing the inspection, store it in the warehouse for future use.
3. Civil engineering template view explanation
After the civil formwork device is installed, the installation technicians and civil technical personnel check the formwork to see if the elevation and scale errors meet the requirements and whether there are any remaining problems affecting the construction of the device. The indicators can be tested before the next process.
(I) Construction process
Manufacture of reserved hole molds → Check and account of civil template → Drainage pipe device positioning and marking → Reserved hole mold device → Quality inspection and inspection (rectification) → Concrete pouring (view protection) → Removal of reserved hole molds → Drainage pipeline device → Reserved Hole plugging
(2) Manufacture of reserved hole molds
1. The reserved hole mold is made of steel pipe, and the reserved hole is selected according to the planned drainage pipe standard 1.4-1.7 times.
2. Use a cutting machine to cut a steel pipe with the same thickness of the cast-in-place plate in the three small rooms, and take out a triangle of about 25px from the side wall of the steel pipe. The fixed iron piece is drilled and welded to the steel pipe for fixing and sealing.
3. Grind and lubricate the welded joint, and brush the release agent on the inner and outer walls for later use.
4. According to the standard of the reserved hole mold, use the waste film board to saw the top cover template, and fix the fixing hole for fixing with the mold.
5. Civil engineering formwork to check the description, the positioning of the drainage pipeline device, the same as the embedded process.
