Water seepage blind drain for basement roof drainage and construction method thereof

Abstract

The invention discloses a water seepage blind drain for basement roof drainage and a construction method thereof, and relates to the technical field of building construction. The water seepage blind drain comprises a PVC drainage pipe, a pipeline non-woven fabric isolation layer, a rubble layer and a rubble layer non-woven fabric isolation layer, the pipeline non-woven fabric isolation layer wrapsthe surface of the PVC drainage pipe, the rubble layer wraps the surface of the pipeline non-woven fabric isolation layer, the rubble layer non-woven fabric isolation layer wraps the surface of the rubble layer, the PVC drainage pipe is laid above a basement roof, pipe holes are formed in the surface of the PVC drainage pipe, the hole diameter of the pipe holes formed in the surface of the PVC drainage pipe is phi 16, the distance between the pipe holes is 200 mm, and the distance between the pipe holes and the pipe bottom is 1/3 or above. According to the water seepage blind drain for basement roof drainage and the construction method thereof, the drainage problem on the basement roof can be effectively solved, and a drainage system is not prone to deformation under the pressure of covering soil; and mechanical construction is not needed in the construction process, operation is easy, and construction is convenient.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a seepage blind drainage for basement roof drainage and a construction method thereof. Background technique [0002] A basement is a room in a building that is below ground level. Building a basement below the ground floor of a house can improve the efficiency of building land use. The foundations of some high-rise buildings are deeply buried, and making full use of this depth to build basements has good economic and practical effects. [0003] With the continuous improvement of people's requirements for construction projects, the basements of most buildings are interconnected, resulting in a very large basement area. People also gradually strengthen the beauty of greening on the top of the basement. Therefore, most buildings are covered with soil on the top of the basement. Ubiquitous, but the existing soil-covered area of ​​the basement roof is prone to roof lea...
