Bailey support system applied to complicated pipe cable crossed protection and construction method thereof

Abstract

The invention discloses a Bailey support system applied to complicated pipe cable crossed protection. The Bailey support system applied to complicated pipe cable crossed protection comprises a type-Isuspension system, a type-II suspension system and four type-III suspension systems, a type-IV suspension system and a type-V suspension system, wherein two of the type-III suspension systems are arranged in front of the type-IV suspension system, and the other two type-III suspension systems are arranged at the rear of the type-IV suspension system and in one-to-one correspondence to the front two type-III suspension systems; the type-II suspension system and the type-I suspension system are arranged sequentially from left to right on the left of the type-IV suspension system; the type-V suspension system is arranged on the right of the type-IV suspension system; the type-II suspension system, the type-IV suspension system and the type-V suspension system are parallel to one another; thetype-I suspension system and the type-III suspension system are parallel to each other and perpendicular to the type-II suspension system. The Bailey support system applied to complicated pipe cable crossed protection facilitates underground pipeline construction, saves cost and avoids risks.

Description

technical field [0001] The invention relates to the technical field of underground pipeline construction, in particular to a Bailey support system applied to complex pipeline and cable intersection protection and a construction method thereof. Background technique [0002] An underground passage was built at a road crossing in a certain area, with an area of ​​4,000 square meters. It was constructed by the open-cut method. This intersection is the main arterial road in the area. The underground pipe network is complex and includes thermal pipes (construction during the heating period), 66KV high-voltage lines, and several 10KV high-voltage lines. , high-voltage control box and some communication lines cannot be relocated. [0003] Thermal pipelines (construction during the heating period), 66KV high-voltage lines, 10KV high-voltage lines, and subway 10KV special lines cross three-dimensionally, with a maximum height difference of 2 meters. Bailey racks cannot achieve cross-c...

AI Technical Summary

Problems solved by technology

[0003] Thermal pipelines (construction during the heating period), 66KV high-voltage lines, 10KV high-voltage lines, and subway 10KV special lines cross three-dimensionally, with a maximum height difference of 2 meters. Bailey racks cannot achieve cross-crossing. If cross-crossing is achieved, the bored pile must be increased by nearly 2 meters , because the excavation depth of the foundation pit is 10 meters, the exposed length of the bored piles is longer after excavation, and the weight of the bailey frame and pipelines are concentrated on the bored piles. At the same time, the project is close to the sea, the monsoon is strong, and the safety risk is relatively large , without crossover scheme
