Abstract

The invention relates to the technical field of cable trench support and discloses a cable trench in-situ support construction method comprising the following steps: (1) constructing a continuous wall, excavating a foundation pit to the bottom of the cable trench; (2) constructing a crown beam to a first ballast support, and taking gutter groove under the cable trench; (3) mounting double-strandedsteel on the top surface of the first ballast support; (4) dragging and changing the beam under the cable trench; (5) pouring a supporting platform for supporting the cable trench and a reinforced concrete retaining wall for encapsulating and protecting the cable trench; and (6) completing the construction of the entire dragging system. The construction method has the beneficial effects of increasing construction efficiency, reducing construction interference, preserving energy and protecting the environment.

Description

technical field [0001] The invention relates to the technical field of cable trench supports, in particular to a construction method for in-situ support of cable trenches. Background technique [0002] Since the reform and opening up, my country's economy has developed rapidly, and urban land has become more and more crowded. Therefore, cities have vigorously developed underground space to alleviate ground traffic and commercial activities. However, due to the complexity of the underground pipelines, it causes a lot of inconvenience to the excavation of the underground engineering foundation pit, especially the high-voltage cables, the cost of relocation is high, the construction period is long, and many factors are not conducive to the construction progress. [0003] Therefore, new requirements, new technologies, and new processes have been put forward for the protection of high-voltage cable trenches. It is very necessary to find a method of protecting high-voltage cable ...
