Rigid waterproof sleeve, also known as steel sleeve. General pool in order to prevent water leakage from the side wall, it is required to install the water pipe on the pool waterproof sleeve, the waterproof sleeve is divided into rigid and flexible two. Allow deformation after installation --- flexibility; No deformation allowed -- rigid.


1, rigid waterproof sleeve, suitable for cast iron pipe, also suitable for non-metallic pipe, but according to the use of pipe wall thickness to modify the size.

2. After the processing of wing ring and steel sleeve, the outer wall shall be brushed with primer (including camphor or cold base oil).

3. The material weight listed in the casing size table is the steel casing (the casing length L value is calculated as 200mm) and the weight of the wing ring. Steel sleeve and wing ring are made of A3 material and welded with T42 electrode.

4, casing wall in the wall, in case of the concrete wall should be switched to the concrete wall, its range of pouring concrete, Ⅱ type casing should be colorful ring (D4) large 200 mm in diameter, and must be poured casing a fixed in the wall. The packing in the casing should be compacted tightly.

5. The thickness of the concrete wall at the waterproof sleeve shall not be less than 200mm; otherwise, one or both sides of the wall shall be thickened, and the diameter of the thickened part shall be at least 200mm larger than the diameter of the wing ring (D4).

6. The rigid waterproof sleeve is filled with oil, asbestos and cement, and compacted tightly after filling.


1. Be familiar with the drawing and analyze how to make and install the embedded casing before manufacturing the casing.

2. Attention shall be paid to the making of water supply and drainage sleeve, and the pipe mouth shall be flat with the wall, beam and column after installation.

3. The steel sleeve shall be fully welded around the hydrofoil ring.

4, pipe slope should be uniform, no slope, roof outlet pipe slope should be appropriately increased.

5. Check whether all pipe fittings have cracks, sandholes and even thickness of pipe wall.

6. Before using the pipe, observe the appearance, irrigation and external wall flushing to check whether there are cracks or sand holes one by one.

7. Check whether all socket joints are in place, firm and compact.

8. Supports and hangers shall be installed in accordance with construction acceptance specifications for pipeline installation.

9. Determine the length of the casing according to the building plan, structural pipe plan and building elevation. Then according to the water supply and drainage plan and large - scale drawings, and refer to the standard atlas to make.

10. When making the waterproof casing, the thickness of the wing ring and the casing shall meet the requirements of the specification. Both sides of the wing ring of the waterproof casing shall be fully welded on both sides, and the welding seam shall be full, smooth and smooth without slag inclusion, bubbles or cracks. After welding, clean up the welding slag, and brush more than two times of anti-rust paint. During the installation, the two ends of the casing shall be clamped and fixed firmly with three or more steel bars, and shall not be skewed.

Installation instructions of waterproof sleeve:

"Installed with civil works"

When the pipe passes through the shear wall foundation, beam and special-shaped column of concrete structure, it should be installed together with civil engineering. The reason is that the secondary pouring between the casing and the concrete is not easy to handle after the holes are reserved. Some can not handle, such as basement foundation concrete shear wall installed rigid waterproof sleeve.

Installation before installation

Refers to the pipe through the concrete floor, ordinary brick wall, generally in the concrete floor reserved holes, ordinary brick wall can be cut through the wall eye. At the floor, disconnect the pipe and install the bushing before installing the pipe. On the brick wall, draw lines, plant support, find good slope, install casing.

First of all, before the installation and use of waterproof pipe, the appearance, irrigation and external wall flushing should be observed to check whether there are cracks or sand holes one by one.

Secondly, check whether all pipe fittings have cracks, whether there is no sand hole, whether the thickness of the pipe wall is uniform.

Again, check that all socket is in place, firm, compact.

After the first, the pipe slope of waterproof sleeve installation should be even, there should be no reverse slope, roof outlet pipe slope should be appropriately increased.

Pipe installation of waterproof sleeve shall be set up with support and hanger according to construction acceptance specifications.

Waterproof casing, anticorrosion and painting measures:

1. Before sand blasting and rust removal, check whether the ovality, wall thickness and material of all waterproof sleeves conform to the material specifications, or they shall not be used.

2. Sand blasting and rust removal shall remove the paint, grease and oxide on the surface of the pipe, and shall be approved and recorded by the QC department and the owner before corrosion prevention and painting.

3. Pipeline anticorrosion shall be carried out according to the drawings and specifications of waterproof sleeve.

4, before painting should be fully stirred to reconcile the primer, with cotton yarn or compressed air to remove the dust and water on the surface of the pipeline, the day of the rust of the waterproof sleeve must be the day of the first primer, the first primer is not dry before the second primer, the pipeline surface primer should be uniform, no leakage point.

5, at both ends of the pipe to leave more than 50mm without painting, with the specifications, wall thickness and material of the pipe together as far as possible derusting, derusting should be marked transplant, after brushing primer, each pipe must be marked transplant.

6. Both ends of the waterproof sleeve shall be sealed after pipe derusting and painting, and protective measures shall be taken to prevent pipeline coating from being damaged during transportation and hoisting.
