[0002] During the construction of gas pipeline projects, valve wells need to be set up between pipelines, and earth excavation is required for the valve wells. If earth excavation is not supported in time, landslides may occur, which will have a certain impact on the construction. In serious cases, landslides may cause injuries. The traditional method is either to excavate with a slope or to use supporting piles for enclosure. Slope excavation requires expanding the working surface and increasing the amount of earth excavation; if supporting piles are used for enclosure, the cost of the pile-pressing machinery and the cost of the pile itself will increase. The most critical thing is that both methods affect the construction period and are extremely expensive.
[0003] At present, in engineering construction, there are two types of support devices after the excavation of the valve well:
[0004] The first method is to drive piles and then set up horizontal supports. This method has low work efficiency, long construction period and very high cost.
[0005] The second method is to use Larsen steel sheet pile support. This method is effective, but it is expensive and uneconomical.
[0006] Therefore, a post-excavation support device for a gas valve well is needed to solve the above-mentioned technical problems. Utility Model Content
