Structure and construction method of flexible waterproof wall-penetrating casing for basement concrete exterior wall

Abstract

The invention relates to a basement concrete outer wall micro embedded type flexible waterproof wall bushing structure. The basement concrete outer wall micro embedded type flexible waterproof wall bushing structure mainly comprises a micro embedded type outer wall, a through-wall pipe, a flexible waterproof bushing, a sealing ring, a flexible jointing material, flange plates, double nuts and stiffening plates. A micro embedded type structure is adopted at the position of the flexible waterproof bushing for the concrete outer wall to form an annular groove, and screws are embedded in the groove. The flexible waterproof bushing is set into an expansion head shape according to the structure of the groove. A water stop ring is arranged in the middle portion of the bushing, and an outer baffle is arranged at the tail portion of the bushing. A pipe body of the through-wall pipe is provided with an inner baffle and a push plate and fixed through the outer flange plate and a short pipe and via the double nuts and the waterproof bushing. The sealing ring is arranged between the short pipe and the inner baffle. The flexible jointing material is arranged between the push plate and the outer baffle. According to the basement concrete outer wall micro embedded type flexible waterproof wall bushing structure, the length of the whole waterproof bushing is effectively reduced, meanwhile, it is guaranteed that the flange plates fully press the sealing ring and the sealing ring does not loosen easily, and detaching in the later period is convenient. The invention further provides a construction method for the basement concrete outer wall micro embedded type flexible waterproof wall bushing.

Description

technical field [0001] The invention relates to a micro-embedded flexible waterproof wall-penetrating sleeve for a concrete outer wall of a basement and a construction method, belonging to the field of main structure engineering. It is suitable for the construction of water supply and drainage pipeline projects in public and civil buildings, especially for the positioning and connection of wall-penetrating pipelines that have special requirements for water stop and vibration, such as basement anti-seepage exterior walls that require waterproofing, and living and fire-fighting pools. Background technique [0002] With the development of my country's construction industry, more and more new materials, new processes and new technologies have been widely promoted and applied in the field of construction. For the anti-seepage water of the basement anti-seepage wall, living and fire pools, etc., the water-stop technical requirements have also been put forward with higher requireme...

AI Technical Summary

Problems solved by technology

[0003] The traditional flexible waterproof wall-piercing sleeve is mainly fixed on the wall through the wing ring welded on the outer diameter. The steel sleeve is welded on the inner wall with a flange with a screw, and the outer wall is welded with a fixed flange. The inner cavity of the tube is set Two retaining rings. At the same time, a sealing rubber ring, a flexible sealing material and a sealing paste are arranged on the outside of the two retaining rings between the wall-penetrating pipe and the steel casing, which can achieve a certain sealing effect and reliable waterproof performance. There are deficiencies in the control of safety and construction costs. On the one hand, there is a large hidden danger of water leakage after the bolts are loose. On the other hand, the flexible waterproof sleeve is long, which increases the cost of materials and causes the fixed flange to be basically exposed outside the wall, which affects the appearance.

[0004] Aiming at the problems of high production cost, difficult construction positioning, and poor durability of the current traditional waterproof flexible casing, an improvement is made on the basis of the existing flexible waterproof casing, and a method that can solve the hidden danger of water leakage between the casing and the wall is proposed. , and can solve the sealing problem between the casing and the pipe, and has a simple structure and low cost flexible waterproof casing structure
