Description

Technical Field

[0001] The utility model belongs to the technical field of tunnel auxiliary structure template installation, in particular to a support frame of an assembled tunnel cable trench template. Background Art

[0002] With the continuous development of highway construction, the ratio of bridges to tunnels in mountainous areas is high, the tunnels are numerous and long, and the supporting facilities are relatively complete. The tunnel structure is mainly composed of two categories: the main structure and the auxiliary structure. Among them, the cable trench is an important part of the auxiliary structure, which provides space for the laying of cables and pipelines used in tunnel operations.

[0003] The formed tunnel usually uses the cable trench boundary as the lateral limit of the tunnel pavement width, where the side of the cable trench near the pavement is the cable trench side wall cast by concrete. The cross section of the cable trench side wall is generally a rectangular cross section, which can be cast and formed in one time by an ordinary one-piece mold. Casting the cable trench on site is also an important part of the tunnel project. Because the traditional assembly template technology has the disadvantages of large labor input, repeated splicing, limited support, and poor linear control, it has been gradually eliminated in engineering construction. In order to reduce labor intensity, some construction units use cable trench trolleys to construct and cast the cable trench side walls, but the cable trench trolley has the disadvantages of high cost, slow speed, and low work efficiency; the assembled tunnel cable trench template has the advantages of fast construction speed, low cost, and easy operation, and is gradually being used in more and more tunnel projects. In the construction and application process of the assembled tunnel cable trench template, it is also necessary to support and position it.
