The depth of the basement of the newly built building is generally-5.1 m to-9 m, and a horizontal buried pipe system arranged below the bottom plate of the basement must not be damaged, otherwise, the basement cannot be repaired.
At present, a buried pipe system mostly adopts a non-header type connection mode, namely each buried pipe well is an independent system, so that thousands of buried pipe well water supply pipes and water return pipes need to be collected on a first-level water collector uniformly arranged on two sides of a building house at a ground source side. In the construction process that a water supply pipe and a water return pipe of the underground well are collected and connected with a first-stage water collecting and distributing device, a large number of local intersections of the water supply pipe and the water return pipe must exist. If a cross pipe ditch mode is adopted at the local intersection of a large number of water supply pipes and water return pipes, the depth of the pipe ditch in one direction is inevitably increased, and the placing requirement of the water supply pipes and the water return pipes can be met. The water supply pipe and the water return pipe are arranged in two pipe ditches in different directions in a crossed pipe ditch mode, so that on one hand, the workload of field ditching is increased; on the other hand, the depth of the conventional pipe ditches is about 1m below the bottom plate of the basement at the bottom, the crossing part of the crossed pipe ditches at least needs to dig the pipe ditches in one direction to about 2m below the bottom plate of the basement at the bottom to ensure the passing of pipelines, and for basements at two or more layers underground, the deeper pipe ditches are easy to have the conditions of silt, water seepage and the like, so that the construction difficulty is greatly increased.
