Description

Technical Field

[0001] This utility model belongs to the field of foundation pit reinforcement technology, specifically relating to a foundation pit reinforcement and protection structure. Background Technology

[0002] Foundation pit reinforcement and protection structures are measures taken to support, reinforce and protect the sidewalls and surrounding environment of foundation pits to ensure the safety of underground structure construction and the surrounding environment. They are one of the core contents of foundation pit engineering. Their core objective is to offset the adverse effects of lateral soil pressure and groundwater seepage caused by foundation pit excavation through structural design, and to prevent foundation pit collapse, surrounding soil settlement or damage to buildings and structures.

[0003] Traditional foundation pit support structures rely on on-site welding, bolt tightening, or concrete pouring to complete reinforcement. This slow support mode is difficult to meet the needs of modern foundation pit engineering for "rapid excavation and immediate protection". For example, in the construction of foundation pits near existing buildings in the core urban area, if the support is not put in time, the soil on the side wall of the foundation pit may creep and deform due to prolonged exposure, causing the surrounding surface to settle or the buildings to tilt. From the perspective of portability and operational flexibility, existing support structures are mostly rigid integral designs, which are bulky, heavy, and lack modular folding functions. Utility Model Content

[0004] The purpose of this utility model is to provide a foundation pit reinforcement and protection structure to solve the problems mentioned in the background art, such as the inability of existing foundation pit reinforcement and protection structures to provide rapid support and the inability of the support structure to be folded and portable.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A foundation pit reinforcement and protection structure includes:

[0007] Connecting fixing plate;

[0008] A support mechanism is fixedly connected to the top of a connecting plate. The support mechanism includes a first support rod, the top of which is connected to a rotating shaft. A second support rod is inserted inside the rotating shaft, and a fixed seat is fixedly connected to the bottom of the second support rod.

[0009] An adjustment mechanism is installed outside the support mechanism. The adjustment mechanism includes a hinge seat, a first hinge rod rotatably connected to the bottom end of the hinge seat, a threaded seat inside the first hinge rod, a second hinge rod rotatably connected to the outside of the threaded seat, a threaded rod inserted inside the threaded seat, and a rotating handle fixedly connected to one side of the threaded rod.

[0010] Preferably, a support member is installed at the bottom end of the first support rod, and the support member is rotatably connected to the first support rod and the second support rod, and the middle part of the support member can rotate.

[0011] Preferably, the first support rod is rotatably connected to the second support rod via a rotating shaft, and both the first and second support rods are fixedly connected to a mounting base.

[0012] Preferably, the adjustment mechanism is provided with an external mounting mechanism.

[0013] Preferably, the first hinge rod and the second hinge rod are rotatably connected, and two sets of the first hinge rod and the second hinge rod are symmetrically arranged on the outside of the hinge seat.

[0014] Preferably, the installation mechanism includes a limiting seat, a limiting rod is inserted into the top of the limiting seat, and a rotating rod is inserted into the outside of one side of the limiting seat.

[0015] Preferably, the top end of the rotating rod has a through-hole groove, the limiting rod is inserted through the limiting seat and the rotating rod, the limiting seat is fixedly connected to the outer wall of the hinge seat, and the hinge seat is installed outside the fixed seat by the insertion of the rotating rod.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] (1) This utility model, through the provision of a hinge seat, a first hinge rod, a second hinge rod, and a threaded seat, enables the threaded connection between the threaded rod and the threaded seat to be made by rotating the rotating handle when the support device needs to be supported. This allows the first hinge rod and the second hinge rod to be hinged and rotated, enabling the upper and lower hinge seats to be supported. When the hinge seats are supported, the rotational connection between the hinge seats and the fixed seat enables the second support rod and the first support rod to be extended and supported, thereby achieving rapid reinforcement and protection of the pit sidewall.

[0018] (2) By setting a first support rod, a rotating shaft, a second support rod and a fixed seat, this utility model enables the adjustment mechanism to be disassembled on the fixed seat by disassembling the installation mechanism when disassembling the support structure. Then, by folding the support member and rotating the second support rod on the rotating shaft, the second support rod and the first support rod can be folded together, so as to realize the convenient disassembly and assembly of the support device.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1:

[0026] Please see Figures 1-4 As shown, a foundation pit reinforcement and protection structure includes:

[0027] Connecting fixing plate 1;

[0028] Support mechanism 2 is fixedly connected to the top of the connecting plate 1. The support mechanism 2 includes a first support rod 201, the top of the first support rod 201 is connected to a rotating shaft 202, a second support rod 203 is inserted inside the rotating shaft 202, and a fixed seat 204 is fixedly connected to the bottom of the second support rod 203.

[0029] An adjustment mechanism 3 is installed outside the support mechanism 2. The adjustment mechanism 3 includes a hinge seat 301. A first hinge rod 302 is rotatably connected to the bottom end of the hinge seat 301. A threaded seat 304 is provided inside the first hinge rod 302. A second hinge rod 303 is rotatably connected to the outside of the threaded seat 304. A threaded rod 305 is inserted inside the threaded seat 304. A rotating handle 306 is fixedly connected to one side of the threaded rod 305. A support member 205 is installed at the bottom end of the first support rod 201. The support member 205 is rotatably connected to the first support rod 201 and the second support rod 203. The middle part of the support member 205 can rotate. The first support rod 201 is rotatably connected to the second support rod 203 through a rotating shaft 202. A fixed seat 204 is fixedly connected to the outside of both the first support rod 201 and the second support rod 203.

[0030] Specifically, when the handle 306 is rotated, it drives the threaded rod 305 to rotate, so that the threaded seat 304 can extend and retract on the threaded rod 305, thereby enabling the first hinge rod 302 and the second hinge rod 303 to hinge, thus realizing the opening operation of the hinge seat 301.

[0031] As can be seen from the above, when it is necessary to raise the foundation pit support device, the handle 306 is first manually rotated to drive the threaded rod 305 connected to it to perform helical transmission within the threaded seat 304. Due to the precise threaded fit between the threaded rod 305 and the threaded seat 304, this rotational motion is converted into linear motion, which in turn drives the hinge joint between the first hinge rod 302 and the second hinge rod 303 to rotate relative to each other. As the angle between the two hinge rods gradually increases, the upper and lower hinge seats 301 will rise synchronously, thereby realizing the vertical raising action of the support device. During the rising process of the hinge seat 301, since its bottom is connected to the fixed seat 204 by a rotatable hinge, this design allows the hinge seat 301 to drive the second support rod 203 to unfold outward at a specific angle while it is vertically rising and falling. At the same time, the first support rod 201 remains fixed as a basic support, forming a stable triangular support structure together with the second support rod 203. Through this linkage mechanism, the entire support system can transform the vertical lifting action into the horizontal support deployment, ultimately achieving efficient and stable reinforcement and protection of the pit sidewall, effectively preventing the collapse and deformation of the pit sidewall, and ensuring construction safety.

[0032] Example 2:

[0033] refer to Figure 3 and Figure 4As shown, an installation mechanism 4 is provided outside the adjustment mechanism 3. The first hinge rod 302 and the second hinge rod 303 are rotatably connected. Two sets of the first hinge rod 302 and the second hinge rod 303 are symmetrically arranged outside the hinge seat 301. The installation mechanism 4 includes a limiting seat 401. A limiting rod 402 is inserted into the top of the limiting seat 401. A rotating rod 403 is inserted into the outside of one side of the limiting seat 401. A hole is opened through the top of the rotating rod 403. The limiting rod 402 is inserted through the limiting seat 401 and the rotating rod 403. The limiting seat 401 is fixedly connected to the outer wall of the hinge seat 301. The hinge seat 301 is limited and installed outside the fixed seat 204 by the insertion of the rotating rod 403.

[0034] Specifically, when the limiting rod 402 is pulled out, the rotating rod 403 can be disengaged from the limiting insertion in the limiting seat 401 and the fixed seat 204, thereby allowing the hinge seat 301 to be disassembled on the fixed seat 204, facilitating the disassembly of the adjusting mechanism 3 on the support mechanism 2. Subsequently, through the rotation of the support member 205, the second support rod 203 and the first support rod 201 can be folded together, realizing the folding installation of the support device.

[0035] As shown above, the operation procedure for disassembling the support structure is as follows: First, by operating the installation mechanism 4, the fixed connection between the adjustment mechanism 3 and the fixed base 204 can be quickly released, thereby separating the entire adjustment mechanism 3 from the support base. After disassembling the adjustment mechanism 3, the support assembly is folded. By manually rotating the support member 205, it is folded inward; simultaneously, the second support rod 203 can be flexibly rotated through the rotating shaft 202 at its bottom, gradually folding it from its original unfolded support state towards the first support rod 201. During this process, the angle between the second support rod 203 and the first support rod 201 gradually decreases, and the two gradually come together, ultimately forming a compact folded shape. This design makes the entire support device not only easy to disassemble and separate, but also significantly reduces the space occupied by folding and retracting each component, greatly improving the device's convenient disassembly and rapid assembly performance. This is beneficial for equipment recovery and transportation after construction and also facilitates efficient installation for subsequent reuse.
