Problems solved by technology

[0003] Due to the long total length of the pipe trench in the prefabricated section of the project, the number of sections is large, the task is heavy, and the safety hazards caused by frequent hoisting operations are great
If there is no scientific and reasonable construction plan in advance, the construction of the pipe trench will not only greatly affect the cost, but also may cause some safety and quality accidents

Abstract

The invention discloses a construction method of a flexible socket and spigot type common pipe trench. The construction method comprises the following steps: S1: prefabricating and manufacturing, and transporting the common pipe trench; carrying out appearance checking on the common pipe trench when the common pipe trench is conveyed into a construction site; S2: carrying out foundation pit digging and foundation treatment on the common pipe trench; S3: mounting and fixedly connecting the common pipe trench, including procedures of positioning and hoisting the common pipe trench, mounting a water stopping rubber ring, mounting a pipe section, and carrying out a closed water test and the next path of procedure; S4: after performing the step S3, carrying out backfilling treatment on a foundation pit; S5: monitoring measured content of a trench bottom foundation pit subjected to the backfilling treatment in the step S4. The construction method disclosed by the invention has the technical effects that the operation of the procedures is relatively simple, and the safety and quality control is facilitated.

Description

technical field [0001] The invention belongs to the field of municipal underground structures, in particular to a construction method for a flexible socket-type common pipe ditch. Background technique [0002] The municipal common pipe trench contains urban water supply and drainage, fire protection, communication, electricity and telecommunications systems, and converts these infrastructures that were originally on the ground into underground, saving a lot of valuable ground space. Due to this important function, municipal pipe trenches have been widely used in domestic urban infrastructure construction. [0003] Due to the long total length of the pipe trench in the prefabricated section of the project, the number of sections is large, the task is heavy, and the safety hazards caused by frequent hoisting operations are great. If there is no scientific and reasonable construction plan in advance, the construction of the pipe trench will not only greatly affect the cost, bu...
