Description

Technical Field

[0001] The utility model belongs to the field of foundation pits, and in particular relates to a supporting structure suitable for deep foundation pits. Background Art

[0002] Foundation pit support is a series of support measures taken during underground excavation to prevent soil collapse, protect surrounding buildings and ensure the safety of workers.

[0003] When the existing foundation pit support structure is used in deep foundation pits, since its support structure is often made of reinforced concrete, its support structure often requires a lot of manpower and material resources during the installation and arrangement process, and its installation process is cumbersome. The support height of the general support structure is fixed, but the inner wall height of the deep foundation pit is much higher than that of the general foundation pit, so it is often difficult to stably support the inner walls on both sides of the upper end of the deep foundation pit, which easily leads to the collapse of the pit mouth of the deep foundation pit.

[0004] Therefore, when the above-mentioned foundation pit support structure is used in a deep foundation pit, the installation and arrangement process of the support structure is relatively cumbersome, time-consuming and labor-intensive, which greatly affects its use cost and convenience during use. In addition, its supporting structure also has the problem of being adjusted in real time according to the inner wall height of the deep foundation pit. A support structure suitable for deep foundation pits is developed. By adding a rotating expansion and folding structure, a telescopic protection structure, and a snap-on installation and positioning structure to the support structure, the device can be flexibly adjusted according to the inner wall height of the deep foundation pit, thereby improving its effect on deep foundation pit support, improving the convenience of the device during installation and use, and reducing its use cost and maintenance cost. Utility Model Content

[0005] In order to overcome the problem that the installation process of the support structure of the deep foundation pit is cumbersome, time-consuming and labor-intensive, and it is difficult to stably support the inner wall of the foundation pit of different depths.

[0006] The technical solution of the present utility model is: a supporting structure suitable for deep foundation pits, including ground nails, and also including a fixing component, a bearing component, a baffle component, a support component, and a telescopic component. The lower end of the bearing component is installed with a fixing component with its own fixing nails, and the bearing component is provided with a storage structure for storing the support component. A baffle component for supporting and limiting the inner wall of the foundation pit is rotatably installed on the bearing component, a telescopic component for up and down lifting displacement is installed in the baffle component, and a support component for assisting the baffle component for positioning is hingedly installed on the baffle component.

[0007] Preferably, by pulling the baffle assembly, the baffle assembly is rotated and unfolded or folded along the inner wall of the supporting assembly, which makes it easier for users to use the device. In conjunction with the rotating support assembly, the support assembly is snap-mounted on the fixing assembly to support and fix the unfolded baffle assembly. The telescopic assembly can then be used to provide secondary auxiliary support according to the depth of the foundation pit, thereby enhancing the support and protection effect of the device on the foundation pit.

[0008] Preferably, the bearing assembly includes a bearing platform, a support platform, a storage slot, a positioning slot, and a slide slot. The upper end of the bearing platform is fixedly connected to a front and rear symmetrical support platform, and a slide slot is provided at the end of the support platform close to each other. Six equally spaced storage slots are provided at the upper and lower ends of the bearing platform, and equally spaced positioning slots are provided at the upper and lower ends of the bearing platform. When in use, the support legs and the hinge blocks can be stored through the storage slots, and the slide slots can limit the connecting columns and assist the support plates in rotating, expanding or storing them, so that users can fold and store the support plates, making it convenient for the use of the device.

[0009] Preferably, the fixing assembly includes a base and a fixing groove. The upper end of the base is connected to the lower end of the supporting platform. The upper end of the base is provided with a matrix-distributed fixing groove. The four corner edges of the lower end of the base are installed with ground nails. When in use, the base can be stably fixed to the ground at the bottom of the foundation pit through the ground nails, and the support legs can be positioned and installed through the fixing groove and the fixing block to support and fix the support plate.

[0010] Preferably, the baffle assembly includes a support plate, a connecting column, a first trough body, a limiting groove, a handle, an anti-slip pattern, a positioning block, and a hinge block. The front and rear ends of the support plate are fixedly connected with connecting columns, and the connecting columns are adapted to the slide groove. The support plates are close to each other and a first trough body is provided. The upper and lower inner walls of the first trough body are provided with limiting grooves. When in use, the support plate can be rotated and adjusted by pulling the handle, and the friction between the support plate and the two sides of the foundation pit can be increased in combination with the anti-slip pattern to enhance the support capacity of the support plate on the foundation pit. The positioning block cooperates with the positioning groove to position and install the unfolded support plate.

[0011] Preferably, a handle is fixed to the upper end of the support plate, anti-slip grooves are fixed to the upper end of the support plate at equal intervals, front and rear symmetrical positioning blocks are fixed to one end of the support plate away from each other, and three hinge blocks are fixed to the lower end of the support plate at equal intervals. When in use, the limit blocks can be assisted in positioning by the limit grooves to enhance the supporting capacity of the telescopic plate and prevent it from displacement, which would cause collapse at the edge of the foundation pit, thereby improving the safety of the device when in use.

[0012] Preferably, the support assembly includes a support leg, a fixed block, and a hinge slot. A hinge slot is provided at the end of the support legs that are close to each other, and the hinge slot is rotatably connected to the hinge block. A fixed block is fixed to the end of the support legs that are away from each other, and the fixed block is adapted to the fixed slot. When in use, the support leg is rotated and adjusted so that the fixed block is installed in the fixed slot, so that the support leg can support and fix the unfolded support plate.

[0013] Preferably, the telescopic assembly includes a telescopic plate, an electric cylinder, and a limit block. The electric cylinder is installed on the inner wall of the end of the first trough body that is away from each other, and the telescopic plate is fixedly connected to the end of the electric cylinder piston rod that is close to each other. The upper and lower ends of the telescopic plate are fixedly connected to the limit blocks. The limit blocks are adapted to the limit grooves, and the outer wall of the telescopic plate fits the inner wall of the first trough body. When in use, the electric cylinder can drive the telescopic plate to move up and down along the inner wall of the first trough body, so as to drive the telescopic plate to provide auxiliary support to the inner wall of the foundation pit that the support plate cannot support.
