Abstract

The invention discloses an underdrainage pipeline construction technology process for municipal engineering and relates to the technical field of pipeline construction. The technology process comprises the following steps of measurement and line alignment of a drainage pipeline, foundation pit supporting, foundation pit processing, foundation construction and UPVC pipeline installation. Accordingto the underdrainage pipeline construction technology process, for rainwater and sewage, foundation pits are adopted and pipe pits are dug, the depth of the pits is 2-9 m, dense-arrangement deep-drawing steel plate piles are adopted for supporting the foundation pits, NO.30 groove steel is adopted for supporting top supporting horizontal supports, the length of the horizontal supports is higher than that of the space before being tightly piled and is kept within 2-6 cm, and accordingly the embedded supports are reasonably pressed; by adopting cooperation of mechanical soil digging and manual soil digging, it is guaranteed that soil at the bottoms of grooves cannot be damaged, during mechanical digging, the digging standard height of the pit is 20-30 cm, the flatness of the soil is checkedthree times after manual soil digging, and accordingly it is confirmed that digging is not excessively conducted; the construction technology is high in efficiency, the construction cost is low, the benefit is high, and the process has great promotion significance on increase of the level of municipal engineering construction in China.

Description

technical field [0001] The invention relates to the technical field of pipeline construction, in particular to a construction process and method for underground drainage pipelines in municipal engineering. Background technique [0002] Urban drainage can be divided into several aspects such as domestic sewage, industrial wastewater and atmospheric precipitation. The urban drainage system must be collected and transported in time, and the sewage should be completely discharged and dewatered. Residents' daily production and life. Underground drainage pipelines in municipal engineering construction require a large investment, so it is very important to carry out construction and management based on various technical requirements. [0003] Problems in the construction of water supply and drainage pipelines for municipal road projects: the common problem in the construction of water supply and drainage pipelines for municipal road projects is the dislocation of pipelines. It is...
