One-time pre-embedded water stop joint for constructional engineering drainage and construction method thereof

Abstract

The invention discloses a one-time pre-embedded water stop joint for constructional engineering drainage and a construction method thereof. According to the one-time pre-embedded water stop joint, through installation of a second water stop section, a push rod pushes a sealing plate to slide downwards, gas in a sleeve enters a liquid tank through a gas pipe, a push plate pushes sealant in the liquid tank outwards to be sprayed to the joint of concrete and a first water stop section, the joint of the concrete and the first water stop section is fully sealed, the situation that when the device is used, due to the fact that sealing of the connecting position of concrete and the first water stop joint is not firm, water seepage occurs, and the daily life of personnel is affected is prevented, meanwhile, gas in the sleeve can enter an inner groove through a communicating pipe, an extrusion plate upwards extrudes sealant in the inner groove to be sprayed to the connecting position of the first water stop joint and the second water stop joint, the situation that sewage flows upwards due to the fact that the part is not firmly sealed, and the good water seepage effect cannot be achieved is prevented, the stability of the device is guaranteed, the device can stably run for a long time, resources are saved, and the construction efficiency is guaranteed.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a disposable pre-embedded water stop section for drainage of construction engineering and a construction method thereof. Background technique [0002] Construction engineering refers to the planning, survey, design and construction, completion and other technical work and the completed engineering entity and the installation project of the supporting lines, pipelines and equipment for new construction, reconstruction or expansion of houses, buildings and auxiliary structures and facilities. . It also refers to the construction of various houses and buildings, also known as construction workload. This part of the investment must be built and used, and can only be realized through construction activities. Among them, the construction projects of "houses and buildings" include factories, theaters, hotels, shops, schools, hospitals and residences, etc. The new cons...

Problems solved by technology

[0004] The purpose of the present invention is to solve the situation that after the pre-embedding in the prior art is completed, the connection between the water-stop joint and the concrete may be unstable due to external factors, and the sufficient and effective sealing between the water-stop joint and the concrete cannot be achieved, resulting in a water-stop joint. In view of the problem of the decline of the water stop efficiency of the water section, a kind of construction engineering drainage one-time pre-buried water stop section and its construction method are proposed
