Embodiment 1

[0072] A construction method for electric pipe arrangement in a miniature pipe jacking pipeline, the method is realized by the following steps:

[0073] S1: Construction of pipe jacking pipeline 1:

[0074] S1.1: If figure 2 As shown, the pipe jacking pipeline 1 is composed of several circular steel pipes connected head to tail along the longitudinal direction; before the steel pipes enter the working well, a rectangular guide rail 2 is welded and fixed longitudinally at the bottom of the inner wall of each steel pipe;

[0075] S1.2: Use the micro pipe jacking method to carry out the construction of the pipe jacking pipeline 1. When welding the steel pipes that have been jacked and the steel pipes to be jacked in the working well, make the guide rails 2 of the two steel pipes face front and back;

[0076] S1.3: Open the first grouting hole outside the soil body at its front end on the top of the side wall of the jacking pipe 1;

[0077] S2: Installation of auxiliary tank 3:...

Embodiment 2

[0115] The composite cement slurry is composed of the following components in parts by mass: 10 parts of cement; 0.8 parts of water glass and 6 parts of water; wherein, the modulus of the water glass is 3.0 and the concentration is 35Be.

Embodiment 3

[0117] Composite cement slurry is made up of the component of following mass fraction: 10 parts of cement; 0.77 part of water glass, 5.8 parts of water; Wherein, the modulus of described water glass is 2.6, concentration is 35Be; This component can improve The bonding performance between the composite cement slurry and the cable pipe, and between the composite cement slurry and the pipe jacking pipe 1 further improves the structural firmness of the cable pipe made by the method.

[0118] In the specific implementation process, the two bottom corners of the tube pillow support plate are provided with bar-shaped grooves that run through the front and rear and are arranged radially, and the rollers 7 are installed in the bar-shaped grooves one by one; the tube pillow 9 is made of Made of high-strength, wear-resistant plastic; the guide rail 2 and the auxiliary guide rail 4 are made of thick-walled square steel with a size of 20mm×20mm; when the guide rail 2 is welded to the steel ...

Abstract

Specifically, the invention is a construction method of electric power pipe arrangement in a miniature pipe jacking pipeline, which solves the problems that the uniformity of electric power pipe arrangement and safety distance cannot be guaranteed during the existing micro pipe jacking construction, which affects its use performance and safety performance. A construction method for electric pipe arrangement in miniature pipe jacking pipelines, which is realized by the following steps: S1: construction of pipe jacking pipelines; S2: installation of auxiliary tanks; S3: installation and fixing of pipe pillow support plates; S4 : construction of the first layer of cable conduit; S5: construction of the middle layer of cable conduit; S6: construction of the top layer of cable conduit; S9: secondary grouting. The method has strong operability, effectively improves the construction efficiency, and reduces the labor cost in the construction; it ensures the uniformity and safety distance of the arrangement of the cable pipes, thereby ensuring the safety performance of the cable pipes constructed by the method.

Description

technical field [0001] The invention relates to a construction method for pipeline engineering, in particular to a construction method for electric pipe arrangement in a miniature pipe jacking pipeline. Background technique [0002] In the construction of traditional power pipelines, pipe trenches need to be excavated first, which is not suitable for construction conditions in narrow spaces and without excavation conditions. Micro-pipe jacking construction can save the step of digging pipe trenches, and can be applied to construction conditions in narrow spaces and inconvenient excavation. [0003] However, practice has shown that the existing micro pipe jacking method has the following problems when it is used in the construction of electric power pipes: since the electric power pipes are hidden inside the pipe jacking pipe, whether the electric power pipes can be evenly arranged cannot be guaranteed, and the safe distance between the electric power pipes There is no guara...
