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

The invention discloses a Bailey bracket system applied to complex pipe and cable crossing protection, including type I suspension system, type II suspension system, type III suspension system, type IV suspension system and type V suspension system, and type III suspension system There are four groups, of which two sets of Type III suspension systems are set on the front side of the Type IV suspension system, and the other two sets of Type III suspension systems are set on the rear side of the Type IV suspension system and are connected with the two sets of Type III suspension systems on the front side. Correspondingly, Type II suspension system and Type I suspension system are set on the left side of Type IV suspension system from left to right, V type suspension system is set on the right side of Type IV suspension system, Type II suspension system, Type IV suspension system and The V-type suspension system is parallel to each other, the I-type suspension system and the III-type suspension system are parallel to each other and perpendicular to the II-type suspension system. The invention makes the construction and operation of underground pipelines convenient, saves costs and avoids safety 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...
