Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit support, in particular to a new foundation pit support structure used in deep soft soil areas. Background Art

[0002] Foundation pit support is a measure of support, reinforcement and protection for the side walls of foundation pits or trenches and the surrounding environment to ensure the safety of underground structure construction and the surrounding environment. Especially during pipeline construction, it is necessary to first set vertical support piles or underground continuous walls on the outside of the foundation pit, and then set up horizontal supports between the support piles or underground continuous walls to prevent the support piles or underground continuous walls from collapsing. With the rapid development of modern urban construction, construction projects in deep soft soil areas are increasing. The geological conditions in these areas are complex, and the soft soil is deep and has a high water content.

[0003] Patent publication number "CN218437087U" discloses a "foundation pit support structure", including a support assembly and a support assembly, wherein the support assembly includes a first support wall and a second support wall, and the support assembly is arranged outside the first support wall and the second support wall, and includes a first purlin, a second purlin and a support member, wherein the first purlin is arranged on the first support wall or the second support wall along a first direction, and the second purlin is located outside the first support wall or the second support wall and connected to the first purlin, and the support member is inserted into the soil outside the support assembly along a second direction and connected to the second purlin. The support assembly can support the support assembly outside, and is easy to install, which can reduce the exposure time of the foundation pit.

[0004] In the above patent, due to the high groundwater level in the deep soft soil area, the soil is rich in water content. The high water content reduces the friction between soil particles and reduces the cohesion, resulting in a decrease in the shear strength of the soil. This will weaken the stability of the foundation pit slope, increase the soil pressure on the supporting structure, and easily cause accidents such as landslides and collapses. Therefore, there is a problem that it is not easy to filter out the water in the soil.

[0005] To this end, the utility model provides a novel foundation pit supporting structure for deep soft soil areas to solve the above problems. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a new foundation pit support structure for deep soft soil areas, which solves the above problems.

[0007] To achieve the above objectives, the utility model is implemented through the following technical solutions: a new foundation pit support structure for deep soft soil areas, including a support frame, a filter mechanism is fixedly connected to the outer surface of the support frame, a drainage mechanism is fixedly connected to the outer surface of the filter mechanism, the filter mechanism includes a guide plate fixedly connected to the outer surface of the support frame, a protective plate is fixedly connected to the outer surface of the guide plate, a plurality of through holes are provided on the outer surface of the protective plate, a filter plate is fixedly connected to the inner wall of the through hole, the drainage mechanism includes a support bracket fixedly connected to the outer surface of the protective plate, and a support rod is fixedly connected to the outer surface of the support bracket.

[0008] Furthermore, a gap is left between the guide plate and the protective plate, and sealing plates are fixedly connected to the upper and lower ends of the guide plate and the protective plate.

[0009] By adopting the above technical solution, the sealing plate is used to prevent mud from entering the guide plate and the protective plate.

[0010] Furthermore, the opening of one end of the through hole close to the guide plate gradually decreases, the through holes are arranged at intervals on the inner wall of the protective plate, and the outer surface of the guide plate is provided with water guide holes.

[0011] By adopting the above technical solution, water in the soil can be filtered through the through holes and the water guide holes, so that the water can flow to the inside of the guide plate.

[0012] Furthermore, a plurality of support plates are arranged on the upper surface of the support rod, and bolts are threadedly connected to the outer surfaces of the support plates, and the bolts are threadedly connected to the upper surface of the support rod.

[0013] By adopting the above technical solution, the support plate can be easily supported by the support rods and bolts.

[0014] Furthermore, there is a height difference between the lower surfaces of the support bracket and the support rod and the sealing plate below the guide plate.

[0015] By adopting the above technical solution, the water filtered from the soil is gathered below the supporting bracket due to the height difference between the supporting bracket and the sealing plate.

[0016] Furthermore, the drainage mechanism also includes a drainage pipe fixedly connected to the outer surface of the sealing plate, and a plurality of grooves are formed at the lower end of the drainage pipe.

[0017] By adopting the above technical solution, the water under the supporting bracket can be easily pumped out through the drain pipe.

[0018] Beneficial Effects

[0019] The utility model provides a novel foundation pit supporting structure used in deep soft soil areas.

[0020] Compared with the prior art, it has the following beneficial effects:

[0021] 1. This new foundation pit support structure used in deep soft soil areas is convenient for filtering water in the soil through through holes and filter plates, so that water enters between the guide plate and the protective plate and finally flows out from the water guide hole. Due to the height difference between the support bracket and the sealing plate, the filtered water in the soil gathers under the support bracket. An external water pump is used to connect the water inlet of the external water pump with the drain pipe, so as to facilitate the extraction of water under the support bracket and prevent water accumulation in the foundation pit.

[0022] 2. This is a new type of foundation pit support structure used in deep soft soil areas. The guide plate and the protective plate are installed inside the foundation pit, and then the inner side of the guide plate is supported by a support frame and a support bracket. The support plate is fixed to the upper surface of the support rod with bolts, which makes it convenient for workers to work on the upper surface of the support plate, preventing the foundation pit from being muddy, hindering the normal operation of construction equipment and personnel, resulting in reduced construction efficiency and delayed construction period.
