Problems solved by technology

[0003] In view of the related technologies mentioned above, the inventor believes that: in the support of deep foundation pits, most of the pile-anchor supports use multiple reinforced concrete bodies as the support bodies to support the inner wall of one side of the foundation pit respectively. The bending moment of the support structure is small, and the ability to resist earth pressure is also poor

Embodiment Construction

[0032] Attached to the following Figure 1-5 This application will be described in further detail.

[0033] The embodiment of the present application discloses a foundation pit support device. refer to figure 1 , the foundation pit support device includes four positioning piles 1 , four positioning piles 1 are evenly distributed at four corners in the foundation pit, and a support assembly 2 is connected between two adjacent positioning piles 1 . The positioning pile 1 and the supporting component 2 cooperate to support the foundation pit on each side wall of the foundation pit. At the same time, the positioning pile 1 and the supporting component 2 are connected to form an integral supporting structure in the foundation pit, and the anti-deformation effect is good. , so that the resistance performance of the foundation pit support device is greatly improved, so that the support for the foundation pit is more stable.

[0034] refer to figure 2 The positioning pile 1 inclu...

Abstract

The application relates to a foundation pit supporting device, which includes positioning piles that interfere with the side wall of the foundation pit, one of the positioning piles is arranged at the corner of the foundation pit, and a support is provided between adjacent positioning piles Assemblies, the support assembly includes a crown beam arranged horizontally, a plurality of support units slidingly connected to the crown beam, both ends of the crown beam are connected with anchor rods 1 for inserting into the foundation pit soil, close to the A connecting assembly is connected between the positioning pile of the first anchor rod and the anchor rod, and a support frame is connected to the supporting unit, and the second anchor rod for inserting into the soil body of the foundation pit is fixedly connected to the support frame. The application has the effect of improving the stability of foundation pit support.

Description

technical field [0001] The present application relates to the field of foundation pit construction, in particular to a foundation pit support device. Background technique [0002] The foundation pit will inevitably cause the deformation of the surrounding soil during the excavation process. The deep foundation pit support refers to the support and support used for the side wall of the deep foundation pit and the surrounding environment in order to ensure the safety of the construction of the underground structure and the surrounding environment of the foundation pit. Reinforcement and protection measures. Common deep foundation pit support forms include deep mixing cement-soil fence, channel steel sheet piles, reinforced concrete sheet piles and bored piles, etc. [0003] In view of the above-mentioned related technologies, the inventor believes that: in the deep foundation pit support, most of the pile anchor support uses a plurality of reinforced concrete bodies as the su...
