Problems solved by technology

However, there are still the following problems in the actual construction and post-maintenance process: (1) There are too many types of casings, which are easy to be confused
(2) The construction process is complicated and there are too many processes
(3) During the secondary sealing, linseed and asbestos cement should not be filled, and water leakage is easy
(4) Once the water leaks, it is difficult to solve, and the later maintenance and management are complicated
(5) The construction period is long, the cost is high, and the quality is difficult to guarantee

Embodiment Construction

[0025] Below in conjunction with accompanying drawing and specific embodiment the present invention will be described in further detail:

[0026] according to figure 2 , the present invention provides a construction technique for replacing the waterproof casing, comprising the following steps:

[0027] (1) Cut the material according to the pipe diameter and pipe section length determined by the design. The pipe section can be made of metal pipe or PVC pipe. Install the water stop ring 2 in the middle of the pipe section 1, and install the connecting joint 3 at both ends of the pipe section. The connection method of the connecting joint It is a detachable fixed connection; the connection joint can be a flange connection joint, a socket connection joint, a threaded connection joint, a clamp type connection joint or a compression type connection joint, and the water stop ring 2 is made of the same material as the pipe section 1, The plastic hydrofoil ring is glued and fixed, an...

Abstract

The invention relates to a waterproof pipeline construction pipeline, in particular to a construction process for an alternative waterproof casing pipe. The process comprises pipe segment pretreatment, treatment of an anti-corrosion layer, a waterproof layer and a river sand coating layer of a waterproof pipe segment, fixing the waterproof pipe segment in a wall in a cast-in-place concrete wall orprefabricated wall procedure, and finally, connecting the two ends of the waterproof pipe segment with an outer pipeline. The construction process for the alternative waterproof casing pipe has the advantages of reducing process difficulty, simplifying process and improving the process quality.

Description

technical field [0001] The invention relates to a waterproof construction technology, in particular to a construction technology for replacing a waterproof casing. Background technique [0002] In 2002, my country released the National Standard Atlas "Waterproof Casing" 02S404 for the setting requirements and construction technology of waterproof casing when pipelines pass through basement exterior walls, pools, toilets, roofs and other rooms with waterproof requirements; the atlas is detailed It stipulates the selection and specific methods of waterproof casings in different occasions, figure 1 It is a construction structure of the prior art, including a casing 1, a wing ring 2 on the casing, a retaining ring 3 on the pipe 4, and linoleum 5 is filled in the position of the pipe retaining ring 3, and the rest of the gap between the casing 1 and the pipe 4 Fill with asbestos cement6. However, there are still the following problems in the actual construction and post-maintena...
