Construction method of water supply and drainage pipeline for home soil in deep backfill area in deep hilly area

Abstract

The invention discloses a construction method of a water supply and drainage pipeline for home soil in a deep backfill area in a deep hilly area. The method sequentially comprises the following steps:performing earthwork backfilling and tamping, performing trench excavation in a back filled and tamped soil foundation, performing bracket mounting in an excavated trench, performing supply and drainage pipeline mounting and correction in the bracket, back filling fine sands to the upper part of a supply and drainage pipeline, binding cover board reinforcing steel bars at the upper part of the back filled earthwork, connecting the bracket to the cover board reinforcing steel bars, pouring cover board concrete onto the cover board reinforcing steel bars. The method has the advantages that stress to the supply and drainage pipeline is changed through the changing of the mounting and structure of the pipeline, and the situation that the pipeline is deformed or even damaged during a subsequent settling process is prevented.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a method for constructing an atrium core soil water supply and drainage pipeline in a deep backfill area in a deep hill area. Background technique [0002] In some deep hilly areas in the prior art, the project occupies a large area, and the above-ground building decoration needs to be considered. The construction content includes various functional buildings, landscape and greening, as well as basic public facilities such as water system reconstruction and lighting, and outdoor projects. The soil quality is as follows: [0003] 1 Silty clay: Located in farmland or fish ponds, it will be cleared in the later stage of field leveling, and it is a non-main soil layer. [0004] 2 Silty clay: mainly located in shallow hills and gentle slopes and inter-hill valleys in the site; the layer thickness is 0.50-8.20m, the average thickness is 1.82m, and the buried depth is 0.00-1.00m...

AI Technical Summary

Problems solved by technology

[0010] Therefore, during the construction process of earthwork backfilling in deep hilly areas, since the earthwork has not been solidified in the rainy season after backfilling, the water supply and drainage pipes of the atrium core soil are constructed according to the conventional construction method, and the sinking of the earthwork is likely to cause damage to the water supply and drainage pipes after installation, deformation of the pipes, and plugging of the pipes. And rework increases the cost
