Trench type prefabricated assembly type cable duct bank and working well installation construction method

Abstract

The invention relates to a trench type prefabricated assembly type cable duct bank and a working well installation construction method. The method comprises the following steps that 1, preliminary installation construction and laying of the trench type prefabricated assembly type cable duct bank are carried out at a corresponding position of the natural ground in advance; 2, after installation construction and laying of the trench type prefabricated assembly type cable duct bank are completed, preliminary installation construction and laying of a working well are carried out at a correspondingposition of the natural ground; and 3, the trench type prefabricated assembly type cable duct bank and the working well which are subjected to preliminary installation construction and laying are combined and installed, constructed and laid as a whole. Compared with the prior art, the method has the advantages of standardized factory production, good quality, high precision, high strength, high bearing capacity, good shock resistance, good impact resistance and the like.

Description

technical field [0001] The invention relates to the technical field of power cable construction, in particular to a trench-type prefabricated cable pipe arrangement and a working well installation and construction method. Background technique [0002] The prefabricated construction method has the characteristics of "standardized design modules, factory-based component production, mechanized construction and installation, and scientific project management", which has a positive role in promoting the comprehensive implementation of standardized design results and standardized construction. In addition, the "fabricated" construction method can greatly shorten the construction period and relieve traffic pressure, so it is necessary to promote its application in large cities with heavy traffic. [0003] In order to promote the "prefabricated parts assembly" of pipes, working wells and cable trenches, many experts and scholars have explored this, but the large-scale application of...

AI Technical Summary

Problems solved by technology

On the one hand, excessive self-weight makes transportation and hoisting inconvenient. On the other hand, for the convenience of hoisting, the volume of prefabricated monomers has to be limited, which increases the structural joints, increases the workload of on-site assembly, and also leads to poor structural integrity and sealing.

[0005] (2) uneven settlement

[0006] (3) The construction area is large

The construction area in the urban area is limited, and large construction equipment cannot enter the site

[0007] (4) Poor flexibility in reconstruction of working we...
