Problems solved by technology

[0003] Since pipeline construction is mostly located in urban areas, the construction space is limited. However, in the prior art, when laying drainage pipelines, trenches need to be excavated, and slopes must be carried out at the same time to ensure the stability of the trenches, which requires a large space; Supporting the trench with steel sheet piles is cumbersome and greatly prolongs the construction period, so it needs to be improved

Embodiment

[0038] A kind of underground drainage pipeline construction technology, with reference to figure 1 , which includes the following steps:

[0039] S100. Surveying and setting out: Professional surveyors will conduct survey control and benchmarking point handover procedures in conjunction with the surveying unit. After piles are connected, surveyors will be organized to retest benchmarking points and wire points in a timely manner, and guide road centers, rainwater and sewage pipelines At the center, measure the temporary benchmarking point.

[0040] S200. Well point installation: The well point construction must be carried out in strict accordance with the operating procedures. When installing the well pipe, determine the reasonable embedding depth according to the measured original ground elevation, and use the water gun to punch the hole with a herringbone pole. The water gun should be vertical , Beware of hole collapse.

[0041] S201. Immediately after the standpipe is ins...

Abstract

The invention discloses a construction process of an underground drainage pipeline, and relates to the technical field of pipeline construction. The construction process includes the following steps of S100, surveying and setting out; S200, well point mounting; S300, groove digging; S400, pipeline concrete foundation construction; S500, pipeline mounting; and S600, pipeline backfilling. A method that machine soil digging is used as a main measure and manual operation is used as an auxiliary measure is adopted. Manual slope repairing is used when the place is dug to the position 30 cm-40 cm away from the groove bottom by a machine, redundant soil at the groove bottom is cleaned away, and therefore the situation that undisturbed soil is disturbed by machine over-digging is avoided; and the soil digging ratio of human to the machine is 20:80, and the cubic meter of earth is stacked outside the position 1.5 m away from the groove side. The construction is easy and convenient, the construction difficulty is low, the construction influence time is greatly shortened, meanwhile, damage to an original structure is low, the reliability of an overall connecting structure is high, the sealingperformance of pipelines is high, and the influence on the safety of the structure is low.

Description

technical field [0001] The invention relates to the technical field of pipeline construction, more specifically, it relates to an underground drainage pipeline construction technology. 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. The investment of underground drainage pipelines in municipal engineering construction is relatively large, so it is very important to carry out construction and management based on various technical requirements. [0003] Since pipeline construction is mostly located in urban areas, the construction space is limited. However, in the prior art, when laying drainage pipelines, trenches need to be excavated, and slopes must be carried out at the same time to ensure the sta...
