Construction method of municipal rain and sewage diversion pipeline

Abstract

The invention relates to the technical field of municipal construction, in particular to a construction method of a municipal rain sewage diversion pipeline. The construction method comprises the following steps of S1, excavating a working foundation pit; S2, installing power equipment; S3, installing pipe jacking equipment; S4, dismantling a guide tube; and S5, pipe jacking. A lubricant comprisesthe following components in parts by weight of 30-40 parts of sodium stearate; 20-25 parts of acrylic emulsion; 15-25 parts of packing; 15-20 parts of water; 3-6 parts of N, N-dimethyl ethanolamine;1-2 parts of hydroxyethyl cellulose and 0.5-1 part of 1,2-propylene glycol. The construction method has the effect of enabling the rain sewage diversion pipeline to be pushed into soil more easily.

Description

Technical field [0001] The present invention relates to the technical field of municipal construction, in particular, involving a construction method of municipal rain sputum split pipeline. Background technique [0002] At present, in order to better improve the utilization rate of water resources, reduce the cost and pressure of sewage treatment, usually, the sewage pipe network is discharged into the sewage pipe network in the initial rainwater. By reinforcing a layer of filter plates in the pipe to divide the space in the pipe into two parts, the sewage and rainwater are entered from the upper half of the filter plate in the conduit, after filtering, after filtering, the sewage is from the pipe The upper half of the filter plate is discharged to the sewage plant treatment, and the rain water is discharged directly from the lower part of the filter plate in the pipe to the river, thereby achieving the processing of rain-saving diversion. [0003] The existing municipal rain sp...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: when the pipeline to be buried is relatively long, the friction between the outer wall of the pipeline and the surrounding soil will gradually increase as the length increases, but the existing lubricating coating will The wear resistance of the lubricating coating is poor, and the lubricating coating may be worn during the jacking process of the rain-sewage diversion pipe, which may lead to greater friction between the rain-sewage diversion pipe and the soil during the jacking process, making the rain The jacking operation of the sewage diversion pipe is more difficult, therefore, there is still room for improvement
