Problems solved by technology

[0002] In urban road widening and reconstruction projects, the geology is relatively complex. During construction, it is necessary to consider both the construction period and the closed traffic problem. If the construction is carried out according to the conventional construction method (grooving and sloping, slotting support), the safety of surrounding buildings cannot be guaranteed. At the same time, the construction cost is increased, and the construction period cannot be guaranteed; in addition, in the conventional construction method, certain trench support measures are required for slotting construction. Once the construction environment changes, the construction conditions are complicated, the construction period is long, and the surrounding pipelines Safety cannot be guaranteed, thereby reducing construction quality

Embodiment Construction

[0029] The following is a further description of the municipal drainage pipeline construction process.

[0030]A municipal drainage pipeline construction process, including measuring and setting out, driving steel sheet piles and dewatering, trench excavation, pipeline foundation, pipeline laying, inspection well masonry, closed water test, trench backfilling and pulling out steel sheet piles. The specific construction steps are as follows.

[0031] 1. Measurement and setting out include the following steps

[0032] Do a good job in the positioning of the trench center, the excavation sideline, and the determination of the center elevation, and encrypt the construction guide points and benchmark points, so that the positions and elevations of each process can be measured at any time during construction.

[0033] (1) Check the benchmarking points and establish a temporary benchmarking point every 60 meters;

[0034] (2) Measure the ground elevation of the pipeline, the center...

Abstract

The invention discloses a municipal drainage pipeline construction technology. The municipal drainage pipeline construction technology is characterized by comprising the steps of measuring, paying off, piling steel sheet piles, dewatering, digging a furrow, laying a pipeline foundation, laying a pipeline, building an inspection well, conducting a closed water test, refilling the furrow and drawing out the steel sheet piles. The municipal drainage pipeline construction technology has the advantages of improving the construction quality, lowering the construction difficulty, shortening the construction period and improving the surrounding pipeline safety.

Description

technical field [0001] The invention relates to the field of urban construction engineering construction, more specifically, it relates to a municipal drainage pipeline construction technology. Background technique [0002] In urban road widening and reconstruction projects, the geology is relatively complex.
