Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit support top bracing for pipe gallery construction, in particular to a foundation pit support top bracing device. Background Art

[0002] An integrated pipeline corridor is an underground urban pipeline integrated corridor, that is, a tunnel space is built underground in the city, which integrates various engineering pipelines such as electricity, communications, gas, heating, water supply and drainage. At present, the commonly used method for excavating pipeline corridors is open excavation of foundation pits. Open excavation and cast-in-place concrete integrated pipeline corridor construction is the most commonly used construction method. This construction method can be used for large-scale operations and the entire project can be divided into multiple construction sections to speed up the construction progress. At the same time, this construction method has low technical difficulty, relatively low project cost, and guaranteed construction quality. After the construction is excavated, a support top support device is used between the top opening of the pipeline corridor and the ground to block and seal the top opening of the pipeline corridor, which supports the top of the pipeline corridor and can withstand the downward pressure caused by vehicles or other heavy objects above, ensuring that the pipeline corridor space is not affected by things on the top.

[0003] For example, a foundation pit support top support device with announcement number CN219825322U, the device forms two spaces by supporting the top plate, the triangular support plate and the triangular guide cover, the two spaces collect and gather rainwater, prevent rainwater from continuing to flow downward through the four walls of the pipe gallery, and avoid increasing the humidity inside the pipe gallery. Through the use of the triangular guide cover and the water drive plate, the rainwater is diverted to the sewer outlet for discharge, and the rainwater is prevented from accumulating near the pipe gallery, and the humidity inside the pipe gallery is prevented from being aggravated, thereby avoiding the situation that the various pipelines inside the pipe gallery are easily damaged by moisture. However, the foundation pit support top support device blocks and filters the top opening of the gap between the triangular guide cover and the triangular support plate through the filtering permeable layer. The rainwater can penetrate into the triangular guide cover through the filtering permeable layer for centralized treatment, but some of the gravel flowing with the rainwater will be thrown on the surface of the filtering permeable layer. As the service life of the foundation pit support top support device is extended, more and more gravel is accumulated on the surface of the filtering permeable layer, which will affect the filtering effect of the filtering permeable layer.

[0004] Therefore, it is necessary to provide a foundation pit support top support device to solve the above technical problems. Utility Model Content
