Water supply and drainage pipe anti-seepage device for constructional engineering and anti-seepage method thereof

Abstract

The invention discloses a water supply and drainage pipe anti-seepage device for constructional engineering and an anti-seepage method thereof. The water supply and drainage pipe anti-seepage device comprises two water supply and drainage pipes, a first anti-seepage device and a second anti-seepage device. A connecting position is arranged between the two water supply and drainage pipes, the first anti-seepage device is arranged on one side of the connecting position, and a second anti-corrosion shell is fixedly arranged on the outer surface of the first anti-seepage device. A second heat preservation layer is fixedly arranged on one side of the second anti-corrosion shell, a plurality of first springs are fixedly connected to one side of the second heat preservation layer, second fasteners are fixedly connected to one ends of the first springs, second rubber layers are fixedly arranged on one sides of the second fasteners, and second water-absorbent resin is fixedly arranged on one sides of the second rubber layers. According to the water supply and drainage pipe anti-seepage device for constructional engineering, the first anti-seepage device and the second anti-seepage device are arranged, the connection position is effectively sealed and wrapped, so that the anti-seepage purpose is achieved, and accidental disasters such as pipeline leakage and breakage caused by incomplete cement pouring are effectively avoided.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to an anti-seepage device and an anti-seepage method for water supply and drainage pipes used in construction engineering. Background technique [0002] Construction installation engineering refers to the engineering process formed by processing and placing engineering raw materials and combining them with the main project assembly in accordance with the engineering construction drawings and the current relevant national engineering specifications. The installation engineering involved in the construction industry includes building water supply and drainage engineering, HVAC engineering, electrical equipment engineering, etc. Building water supply and drainage engineering is a branch of water supply and drainage engineering, and also a branch of building installation engineering. Mainly divided into: building water supply system, building drainage system (including...

AI Technical Summary

Problems solved by technology

[0004] 1. In the process of pouring cement mortar, it is easy to cause leakage due to incomplete pouring and difficult to maintain in the later stage. If the pouring is not complete, it may cause accidental disasters such as pipeline leakage and rupture. If the water supply and drainage pipeline ruptures, it will not only It is a waste of water resources and may cause certain economic losses

[0005] 2. The technical difficulty of grouting and plugging holes is high, the water-cement ratio is difficult to control, the operation requirements are high, and the anti-seepage effect is not very good. Only after repeated treatments can it meet the qualified requirements, which brings more work to construction personnel The quantity and the work efficiency are low. After the cement mortar is poured and formed, if there is a problem in the follow-up, it is inconvenient to repair, which will increase the difficulty of the follow-up repair work.

[0006] 3. The protection effect of the existing water supply and drainage pipe connectors is not good. The connection between the drainage pipe and the drainage pipe is connected by a conventional connector, and the sealing effect is poor, and a small amount of water leakage often occurs

[0007] 4. Most of the existing anti-leakage devices do not have thermal insulation effect. In areas where the external environment temperature changes greatly, the anti-leakage device and the joint of the drainage pipe will expand with heat and contract with cold, resulting in poor anti-leakage effect

[0008] 5. After the existing anti-leakage device is used for a long time, the outside of the connecting piece will be corroded, resulting in poor anti-leakage effect
