Underground pipe embedding construction method

Abstract

The invention provides an underground pipe embedding construction method. The method comprises the steps of 1, pipeline trench digging; 2, cushion construction; 3, pipeline installation and fixing; 4,pipe embedding concrete formwork construction; 5, pipe embedding concrete construction; 6, treatment of pipe embedding concrete construction joints; 7, trench backfill. The construction method solvesthe technical problems of the instability of a pipe and water seepage and leakage in pipe joints, and moreover, the method has the advantages of environmental friendliness and safe and civilized construction.

Description

technical field [0001] The invention belongs to the technical field of underground pipe body construction, and in particular relates to an underground pipe body wrapping construction method. Background technique [0002] With the development of cities, domestic sewage and industrial sewage are increasing. my country's per capita water resources are 2,240 square meters, which is one of the 13 water-poor countries in the world. The per capita water resources are only 1 / 4 of the world's average. According to the data, the proportion of surface water that the human body is not suitable for direct contact has reached 32.3%; the water quality of groundwater is still seriously polluted. There are more and more underground pipelines needed, but they are often damaged by the surface, or the pipeline is suspended due to the rise of the river water level, causing displacement and deformation, resulting in pipeline leakage and sewage seepage, deteriorating the surrounding water quality ...
