Device for avoiding buried pipeline sedimentation in room subsoil backfill region and construction method

Abstract

The invention discloses a device for avoiding buried pipeline sedimentation in a room subsoil backfill region and a construction method. The device comprises a pipe hanger. The upper end of the pipe hanger is connected with anchoring components in a concrete ground beam or a reinforced concrete floor. The center of the bottom of the pipe hanger is connected with a U-shaped clamp. The construction method includes the steps of arranging the pipe hanger in a pipeline trench, arranging a pipeline at the bottom of the pipe hanger and fixing the pipeline through the U-shaped clamp, performing a hydraulic test or a closed water test, performing trench backfill, performing floor construction and the like. The device and the construction method have the beneficial effects that defects existing in the prior art are overcome, the stress carrier of the pipeline is changed fundamentally, the problems of pipeline blocking and breakage and the like caused by foundation settlement are eliminated completely, and the safety and normal use of the pipeline are guaranteed, so that construction quality is guaranteed, the economic loss is reduced, and good practicability is achieved.

Description

technical field [0001] The invention relates to the construction of a civil building water supply and drainage pipeline, more specifically, the invention relates to a device and a construction method for avoiding the settlement of the water supply and drainage pipeline in the backfilling area of ​​the civil building core. Background technique [0002] At present, in many residential projects using raft foundations, the water supply and drainage pipes are buried on the first floor. This laying method has the following disadvantages: [0003] (1) Since the water supply and drainage pipelines of the first floor are located in the backfill area of ​​the atrium core soil, and the quality of the atrium core soil backfill is extremely difficult to control, the backfill soil often settles, resulting in the buried water supply and drainage pipelines being blocked due to subsidence or fracture. [0004] (2) Since the water supply and drainage pipes are laid underground, it is often d...

AI Technical Summary

Problems solved by technology

[0003] (1) Since the water supply and drainage pipelines of the first floor are located in the backfill area of ​​the atrium core soil, and the quality of the atrium core soil backfill is extremely difficult to control, the backfill soil often settles, resulting in the buried water supply and drainage pipelines being blocked due to subsidence or fracture

[0004] (2) Since the water supply and drainage pipes are laid underground, it is often difficult to find the blockage or breakage in a short period of time. Once damaged, the user will not be able to use it

[0005] (3) If the water supply and drainage pipes that are clogged or broken are located indoors, their maintenance will be inconvenient. First, it will have a great impact on the lives of the residents. Second, due to the inconvenience of maintenance, the renovated floors of the residents will need to be demolished. resulting in large economic losses
