Problems solved by technology

[0010] The above-mentioned existing technical solutions have the following defects: since the pipeline construction is located in the urban area, the construction space is limited. However, when laying the drainage pipeline, it is necessary to excavate the trench, and at the same time carry out grading to ensure the stability of the trench, which requires occupation of The space is large; at the same time, the trench needs to be supported by steel sheet piles, and the construction is cumbersome, which greatly prolongs the construction period

Embodiment Construction

[0046] The present invention will be described in further detail below.

[0047] A municipal drainage pipeline construction method disclosed by the invention comprises the following steps:

[0048] S1. Measurement and setting out: according to the drawings, use the total station to stake out the sidelines on both sides of the groove, and sprinkle white ash marks.

[0049] S2. Pile foundation positioning: along the outer contour lines on both sides of the trench, release the position of the stirring pile, and the distance between adjacent stirring piles is the diameter of the stirring pile, and the diameter of the stirring pile should be 500-1000mm. The distance from the center of the stirring pile to the outer contour of the groove is the radius of the stirring pile. Therefore, the formed stirring piles can interlock without affecting the excavation of the trench.

[0050] S3. Forming the mixing pile: After placing the pile position of the stirring pile, move the mixing pile...

Abstract

The invention relates to a municipal drainage pipeline construction method, and relates to the technical field of municipal pipeline installation. The municipal drainage pipeline construction method includes the following steps of S1, surveying and setting out, S2, pile base positioning, S3, stirring pile formation, S4, repeated stirring and lifting, S5, trench excavation, S6, heel block laying, S7, drainage pipeline installation, S8, concrete cushion pouring, and S9, soil backfilling. Before trench excavation, mutually-engaged stirring piles are formed on the two sides of a trench, thus the stirring piles can reinforce and support the side walls of the trench and can prevent water on the outer side of the trench from permeating into the trench to affect drainage pipeline installation, sloping and support of the trench during trench excavation are avoided, and the occupied area during trench excavation is decreased.

Description

technical field [0001] The invention relates to the technical field of municipal pipeline installation, in particular to a municipal drainage pipeline construction method. Background technique [0002] With the continuous expansion of the city scale, the water supply and drainage pipeline project, as one of the infrastructures of urban development, is one of the basic guarantees to promote urban development and meet people's daily needs. [0003] Currently, the laying of municipal sewer pipes involves the following steps: [0004] S1, measuring and setting out: setting out the groove position and slope line; [0005] S2. Trench excavation: When the depth of the trench is less than 3m, adopt the large excavation method of slope grading, and the slope coefficient is 1:0.5. Coefficient 1: 0.5, and steel sheet piles or wooden sheet piles are used for support; [0006] S3. Foundation pouring: cleaning the bottom of the tank and pouring a concrete cushion; [0007] S4. Pipelin...
