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

[0002] During the construction of buildings, it is necessary to excavate foundation pits to form the foundation. The inner wall of the foundation pit needs to use a foundation pit support device to improve the strength of the foundation and the inner wall of the foundation pit. The foundation pit support device is a device used for the support of the foundation pit foundation, aiming to ensure the construction safety of the underground structure and the surrounding environment of the foundation pit. It ensures the safety of the side wall and the surrounding environment by adopting retaining, reinforcement and protection measures. The design and application of this device are mainly to meet various requirements such as urban high-rise buildings, underground parking lots, high-rise building burial depths, and civil air defense. With the rapid development of urban high-rise buildings, the demand for support is also increasing day by day. The composition and structure of the foundation pit support device are diverse. In terms of application, the foundation pit support device is suitable for different geological conditions and engineering requirements. For example, for cohesive soil layers, sandy soil layers or foundation pits that need to be excavated to a greater depth, different support methods may be adopted. These support structures are selected according to the depth of the foundation pit and the safety level of the surrounding environment to ensure the stability of the soil wall of the foundation pit and the construction safety. However, in the common foundation pit support devices on the market, during the support process, water seepage easily occurs around the foundation pit, and this water cannot be drained out, affecting the support strength and support effect. Moreover, during the support process, the support device is prone to displacement due to external factors, and it takes a lot of effort to control the support device to reset. Summary of the Utility Model

[0003] An embodiment of the present disclosure relates to a foundation pit support device. When the device body and the rear component structure are displaced due to external factors, the control adjustment structure can be directly controlled to rotate. The adjustment structure controls the force-bearing block structure to move downward through the thread. The force-bearing block structure drives the pull rod to move downward together. The pull rod also displaces inside the force-bearing groove and the vertical groove. Since the force-bearing groove is an inclined structure, after the pull rod moves downward, a backward pushing force is generated, so that the force-bearing plate assembly drives the device body to displace and fit with the inner wall of the foundation pit, enabling the device body to quickly restore the support effect and support strength.

[0004] In the first aspect of the present disclosure, a foundation support device is provided, specifically including: a device body; a bottom groove is opened at the bottom of the front end of the device body, the bottom groove is a groove with two protrusions at the bottom, two T-shaped grooves are opened at the top end of the bottom groove, and uniformly arranged top grooves are provided at the front end of the device body. The bottom of the arc-shaped top groove communicates with the top end of the bottom groove; a rear component structure; the rear component structure is installed behind the device body, and two rectangular force-bearing block structures are installed inside the U-shaped rear component structure. Threaded holes are provided inside the force-bearing block structures, a pull rod is fixed outside the force-bearing block structures, and the outer end cross-section of the pull rod is a circular structure.

A net plate assembly made of a metal material covers the inside of the bottom groove, and two T-shaped splicing joints are fixedly arranged at the top end of the net plate assembly. The splicing joints are inserted inside the T-shaped grooves.

[0006] In at least some embodiments, six transverse grooves are penetrated and opened in the rear component structure, and the sliding block assemblies are inserted and freely slide left and right inside the transverse grooves. A vertical groove is penetrated and opened inside the rear component structure, and the pull rod is inserted inside the vertical groove; an adjustable structure that can rotate freely is installed at the bottom end inside the rear component structure through a rotating shaft, and the adjustable structure with external threads is inserted and rotated inside the threaded hole to control the force-bearing block structure to move up and down freely.

During the support process, if water seeps out from the inner wall of the pit, the water can flow through the top groove for guidance, so that the water flows downward, and then seeps into the inside of the bottom groove through the net plate assembly. Then, the bottom groove controls the liquid to be discharged through the liquid outlet pipe, avoiding the liquid continuously staying on the inner wall of the device body and affecting the support strength and the hardness of the inner wall of the pit.

[0009] During the use process, if the device body and the rear component structure are displaced due to external factors, the adjustment structure can be directly controlled to rotate. The adjustment structure controls the force-bearing block structure to move downward through threads. The force-bearing block structure drives the pulling rod to move downward together. The pulling rod also displaces inside the force-bearing groove and the vertical groove. Since the force-bearing groove is an inclined structure, after the pulling rod moves downward, a backward pushing force is generated, causing the force-bearing plate assembly to drive the device body to displace and fit with the inner wall of the foundation pit, enabling the device body to quickly restore the support effect and support strength.

Two T-shaped grooves are opened at the top end of the bottom groove 107 for inserting splicing joints for connection. The front end of the device body 1 is provided with evenly arranged top grooves 106. The bottom of the arc-shaped top groove 106 communicates with the top end of the bottom groove 107, enabling the top groove 106 to contact the wall, generating a water flow channel. When water seeps out from the inner wall of the foundation pit, it flows downward through the top groove 106, then converges through the bottom groove 107, and finally is discharged through the liquid outlet pipe 105, preventing water accumulation inside the device body 1 and affecting the strength of the foundation pit and the support effect; a rear component structure 2; the rear component structure 2 is installed behind the device body 1. Two rectangular stress block structures 204 are installed inside the U-shaped rear component structure 2. Threaded holes are provided inside the stress block structures 204. Pulling rods 205 are fixed outside the stress block structures 204. The outer end cross-section of the pulling rods 205 is a circular structure. If the device body 1 and the rear component structure 2 are displaced due to external factors, the adjustment structure 203 can be controlled to rotate, and the stress block structures 204 are controlled to move downward through the threads. The stress block structures 204 drive the pulling rods 205 to displace together. The pulling rods 205 displace inside the stress grooves 104, pushing the stress plate assembly 102 and the device body 1 to displace, and re-fitting with the inner wall of the foundation pit to restore the support effect.

[0025] In the embodiments of the present disclosure, as Figure 3 and Figure 4As shown, a uniformly arranged connecting plate 101 is fixed to the rear of the device body 1. Two connecting plates 101 at the same height are symmetrically arranged and used to connect with the force-bearing plate assembly 102 to improve the connection strength. The force-bearing plate assembly 102 is fixed at the middle position of the rear end of the device body 1. The force-bearing plate assembly 102 is fixed between the connecting plates 101 and fixedly connected to the connecting plates 101. The force-bearing plate assembly 102 is inserted into the interior of the rear component structure 2. Three sliding block assemblies 103 for guiding are respectively fixed on both sides of the connecting plate 101 and inserted into the interior of the transverse groove 201, enabling the force-bearing plate assembly 102 to perform a transverse guiding displacement inside the rear component structure 2. Two force-bearing grooves 104 are vertically penetrated through the interior of the connecting plate 101. The force-bearing grooves 104 are inclined. The outer end of the pulling rod 205 is inserted into the interior of the force-bearing groove 104 and freely slides, pushing the force-bearing plate assembly 102 and the device body 1 to move horizontally. Two liquid outlet pipes 105 are fixed to the bottom of the rear end of the device body 1. The interior of the liquid outlet pipe 105 is communicated with the interior of the bottom groove 107, and the liquid inside the bottom groove 107 can be discharged. A net plate assembly 108 made of a metal material covers the interior of the bottom groove 107. Two T-shaped splicing joints are fixed to the top of the net plate assembly 108. The splicing joints are inserted into the T-shaped grooves to drive the net plate assembly 108 for positioning and splicing use.

[0026] In the embodiment of the present disclosure, as Figure 5 shown in Figure 6 the rear component structure 2 is vertically penetrated with six transverse grooves 201. The sliding block assembly 103 is inserted into the interior of the transverse groove 201 and freely slides left and right. A vertical groove 202 is vertically penetrated through the interior of the rear component structure 2. The pulling rod 205 is inserted into the interior of the vertical groove 202, enabling the pulling rod 205 to perform a vertical guiding displacement. An adjustable structure 203 that can freely rotate is installed at the bottom end inside the rear component structure 2 through a rotating shaft. The adjustable structure 203 with an external thread is inserted into the interior of the threaded hole and rotates to control the force-bearing block structure 204 to freely move up and down, driving the pulling rod 205 to move up and down together. A bottom rod structure 206 is welded and fixed to the bottom side of the rear component structure 2 for connecting and using the support member 207 to improve the strength of the support member 207. Support members 207 with a wedge-shaped front end are welded to both ends of the bottom rod structure 206 and the front end of the rear component structure 2. A bottom plate structure 208 with a rectangular structure is welded and fixed to the bottom of the front end of the support member 207 to increase the support area and support strength.

[0027] Working principle of this embodiment: When it is necessary to use the device body 1 and the rear component structure 2 to support the inner wall of the foundation pit, the splicing joint can be controlled to insert into the T-shaped groove, so that the mesh plate assembly 108 is embedded and fixed inside the bottom groove 107. The device body 1 is controlled to contact the inner wall, so that the support member 207 and the bottom plate structure 208 contact the ground, and the device body 1 is stably supported for use, improving the support effect and strength. During the support process, if water seeps from the inner wall, the water flows downward inside the vertical groove 202, enters the bottom groove 107 for collection, and then is discharged through the liquid outlet pipe 105 to avoid liquid residue, which may affect the strength of the foundation pit and the support effect. If the rear component structure 2 is displaced due to external factors, the force receiving block structure 204 can be directly controlled to move downward through the adjustment structure 203, driving the pull rod 205 to move together. The pull rod 205 is guided and displaced inside the vertical groove 202 and the force receiving groove 104, so that the force receiving plate assembly 102 is forced to move horizontally, driving the device body 1 to fit the inner wall and restoring the support effect.
