An anti-seepage device and anti-seepage method for water supply and drainage pipes for construction engineering

Abstract

The invention discloses an anti-seepage device for a water supply and drainage pipe for construction engineering and an anti-seepage method thereof, comprising a water supply and drainage pipe, a first anti-seepage device and a second anti-seepage device. A joint is provided between the water supply and drainage pipes, a first anti-seepage device is provided on one side of the joint, and a second anti-corrosion casing is fixed on the outer surface of the first anti-seepage device. The second anti-corrosion casing is a One side of the second heat preservation layer is fixedly provided with a second heat preservation layer, one side of the second heat preservation layer is fixedly connected with several first springs, one end of the first spring is fixedly connected with a second fastener, and one side of the second fastener A second rubber layer is fixed, and a second water-absorbing resin is fixed on one side of the second rubber layer. The present invention provides a first anti-seepage device and a second anti-seepage device to effectively seal and wrap the connection, thereby achieving The purpose of anti-leakage is to effectively avoid accidental disasters such as pipeline leakage and rupture caused by incomplete cement pouring.

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
