Problems solved by technology

[0004] The above existing technical solutions have the following defects: when the length of the pipeline to be buried is long, the friction between the outer wall of the pipeline and the surrounding soil will gradually increase with the length of the pipeline, and the friction may even increase. As much as the jacking force generated by the jacking equipment is even greater, so that the construction progress of the pipe jacking may be affected, so there is still room for improvement

Embodiment 1

[0070] refer to figure 1 , is a kind of sewage pipeline construction technique disclosed by the present invention, comprising the following steps:

[0071] Step (1), digging working well, specifically as follows:

[0072] Determine the laying position of the sewage pipeline according to the design drawings, and excavate several working wells in the length direction of the sewage pipeline, and control the distance between adjacent working wells to be 50m.

[0073] Step (2), install jacking equipment, details are as follows:

[0074] First fix the jacking equipment on one side of the working well, and then fix the base on the bottom wall of the working well, and the base is close to the side opposite the working well and the jacking equipment, and is used for the sewage pipeline during the jacking process. Pre-positioning.

[0075] Step (3), install the pipe jacking equipment, as follows:

[0076] Install the pipe jacking machine on the base first, then install the pipe jack...

Embodiment 2

[0085] The difference with embodiment 1 is:

[0086] The consumption of each component that adds in the step (5) is as follows:

[0087] Sodium stearate 52.5kg; acrylic acid emulsion 30kg; water 15kg; sodium hexametaphosphate 2kg; polyvinyl alcohol 1.25kg; oleic acid 1.5kg.

Embodiment 3

[0089] The difference with embodiment 1 is:

[0090] The consumption of each component that adds in the step (5) is as follows:

[0091] Sodium stearate 55kg; acrylic acid emulsion 32.5kg; water 10kg; sodium hexametaphosphate 3kg; polyvinyl alcohol 1kg; oleic acid 1kg.

Abstract

The invention relates to the technical field of municipal pipeline construction, and relates to a sewage pipeline construction process. The sewage pipeline construction process comprises the followingsteps of (1) excavating a working well; (2) installing jacking equipment; (3) mounting a jacking pipe; (4) dismantling the jacking pipe; (5) coating a lubricating layer; and (6) jacking a sewage pipeline. A lubricant comprises the following components of, by mass part, 50-55 parts of sodium stearate, 30-35 parts of acrylic emulsion, 10-15 parts of water, 1-3 parts of sodium hexametaphosphate, 1-1.5 parts of polyvinyl alcohol and 1-2 parts of oleic acid. The sewage pipeline construction process has the effect of improving the construction efficiency of the sewage pipeline.

Description

technical field [0001] The invention relates to the technical field of municipal pipeline construction, in particular to a sewage pipeline construction process. Background technique [0002] At present, the sewage pipe network is an important part of the municipal drainage system. The sewage pipe is the most important part of the sewage pipe network. The impact of environmental water bodies. The laying of sewage pipes is the most important part of the laying of sewage pipe network. [0003] In order to solve the problems of damage to urban buildings and road traffic congestion during pipeline burying construction, sewage pipelines are usually constructed by pipe jacking. Pipe jacking construction is a pipeline burying construction technology that does not excavate or reduces excavation. Pipe jacking construction is to use the jacking force generated by jacking equipment in the working pit to overcome the friction between the pipeline and the surrounding soil and push the p...
