Non-migration suspension protection system and method for communication pipes and cables

Abstract

The invention provides a non-migration suspension protection system and method for communication pipes and cables. The method includes the following steps: digging a pipe suspension construction passageway at the position of original communication pipes and cables; positioning and binding the original communication pipes and cables through positioning frames; excavating holes under a pipe cluster of the original communication pipes and cables and using earth layers, which are not excavated, at the two sides as support points to install suspension cradles over the original communication pipes and cables; building a drilling pile at each of the two sides of the pipe cluster and preparing to prefabricate pile supporting stands on site; excavating temporary support walls at the two ends of the line cluster, and a base and the earth layers at the lower part to an appropriate depth and manufacturing the pile supporting stands through casting so as to support the original communication pipes and cables; and packaging the original communication pipes and cables. The system has the characteristics that a non-migration and in-situ protection scheme is implemented on the original communication pipes and cables which pass through a deep foundation pit of a planned subway station so that construction of the deep foundation pit of the planned subway station is not affected; at the same time, the system also has the characteristics of uninterrupted communication, high protectiveness, short construction time, high efficiency, low cost, and easy popularization and application and the like.

Description

technical field [0001] The present invention relates to the field of construction of communication pipeline engineering and underground structures of municipal engineering (such as underground railways, underground roads, underground parking lots and underground streets, shops and underground substations, etc.), and in particular to a non-migrating type of communication pipeline and cables. Suspension protection system and method. Background technique [0002] With the upgrading and transformation of my country's urbanization, the infrastructure construction of my country's urbanization has been accelerated, especially the construction of urban subway rail transit. However, judging from the construction process of subway rail transit construction projects, communication accidents occur frequently, such as communication pipeline blockage, serious damage to communication pipelines, partial or complete interruption of communication cables, etc. These accidents not only cause se...

AI Technical Summary

Problems solved by technology

Although it can solve the construction problem of the deep foundation pit 01 of the subway station, it also brings repeated (secondary) blocking communication; large amount of relocation and cutover, difficult construction; high communication failure rate; large investment , high cost; poor safety; low construction efficiency, long construction time, etc.
