Description

Detachable anti-seepage sleeve assembly

Technical Field

The utility model relates to a construction field, especially dismantled and assembled prevention of seepage sleeve pipe subassemblies.

Background

The existing method for building water supply and drainage pipeline to penetrate floor slab and arrange waterproof sleeve has three types:

(1) the finished U-PVC anti-seepage sleeve is embedded in a concrete floor slab for times, as shown in national standard drawing 10S406 pages 34 and 35, the defect that ① anti-seepage sleeve is easy to damage is that the U-PVC anti-seepage sleeve is made of plastics and is often crushed by bundles of steel bars, steel pipes, wood or hoppers pressed on the U-PVC anti-seepage sleeve in the construction process, the defect of the point (3) appears when the floor slab needs to be broken and the hole is embedded for the second time, and the application range of ② is limited, the U-PVC anti-seepage sleeve can only be used when the U-PVC drainage pipeline penetrates the floor slab according to the specification requirement, and building drainage pipelines made of other materials cannot be protected by the U-PVC anti-seepage sleeve when the floor slab penetrates.

(2) The rigid waterproof sleeve is embedded in the concrete floor for times, as shown in pages 35 and 36 of the national standard atlas 13S409, the rigid waterproof sleeve is easy to deviate during installation ①, the rigid sleeve is often subjected to deviation in installation and cannot penetrate through a vertical pipe even if the rigid sleeve is positioned by a laser vertical instrument due to the lack of a positioning device, the rigid waterproof sleeve is easy to deform after installation ②, the rigid waterproof sleeve in the figure is not detachable and higher than the concrete floor, the rigid waterproof sleeve is higher than the sleeve of the concrete floor in the installation and detachment process of an upper -layer shear wall and floor formwork support system, the rigid waterproof sleeve is often flattened by a steel pipe or is easily damaged by people, the floor needs to be broken, holes are newly repaired and embedded for two times, the following defect in the point (3) appears, and the rigid waterproof sleeve is easy to corrode after installation ③, and is easily affected by a damp environment after installation due to the fact that the rigid waterproof sleeve is made of welded steel pipes.

(3) When a building water supply and drainage pipeline passes through a floor slab, a sleeve is sleeved into the pipeline and is placed into the floor slab to be secondarily filled with fine stone concrete, such as page 35 of the national standard atlas 10S406, the defect that construction joints are easy to form around ① sleeves to leak due to the fact that the secondary filling of the fine stone concrete is adopted, the treatment of the reserved holes before filling is improper (such as the periphery of the hole is not roughened or cleaned, or concrete is not compact enough in the filling process, and the floor slab is prone to water seepage due to the fact that construction joints exist between the sleeve and the secondarily poured concrete and between the reserved holes and the secondarily poured concrete) is overcome, the construction process ② is complicated, the total number of 9 hole construction processes is 9, the reserved holes, the correction, the hole roughening, the cleaning, the sleeve corrosion prevention, the sleeve placement in the hole, the support of the hole, the pouring of the concrete twice, the removal of the hanging mold and the garbage cleaning are high in labor cost and are not beneficial to accelerating the construction progress.
