Description

Technical Field

[0001] This utility model relates to the field of foundation pit support structure technology, and in particular to a foundation pit support structure for civil engineering. Background Technology

[0002] In civil engineering, foundation pit support is a protective measure taken to ensure the safety of underground structure construction and the surrounding environment of the foundation pit, to facilitate construction operations, and to ensure the safety of workers.

[0003] Traditional civil engineering foundation pit support methods include various approaches. For example, baffles are used to press and attach to the sidewalls of the foundation pit, and then steel pipes are used during construction to press and stabilize the baffles on both sides, thus ensuring the safety of the foundation pit's sides. However, in actual use, it has been found that during the civil engineering process, the soil on the sidewalls of the foundation pit may become soft due to weather or rain. In this case, the baffles may not provide adequate support, and the length of the steel pipes may be difficult to adjust, which affects the safety of the foundation pit and reduces the effectiveness of the support structure, thus having certain limitations. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of existing technologies, such as the soil on the side wall of the foundation pit becoming soft due to weather or rain during the civil engineering process, which makes it difficult for the baffle to play a good supporting role, and the length of the steel pipe is difficult to adjust, thus affecting the safety of the foundation pit and reducing the effectiveness of the support structure. Therefore, this utility model proposes a foundation pit support structure for civil engineering.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a foundation pit support structure for civil engineering, comprising two support plates, a support device provided on one side of the two support plates that are close to each other, the support device comprising a connecting frame, support rods rotatably connected to both sides of the surface of the connecting frame, and clamping plates clamping at both ends of the support rods, the clamping plates clamping onto the surface of the support plates, a threaded rod threaded through the surface of the connecting frame, one end of the threaded rod rotatably connected to a bottom plate installed on the inner wall of the foundation pit, two stabilizing rods fixedly connected to the surface of the bottom plate, the two stabilizing rods being slidably connected through the surface of the connecting frame.

[0006] The effects achieved by the above-mentioned components are as follows: when providing protective support for civil engineering foundation pits, it is possible to conveniently squeeze and protect both sides of the foundation pit; when the soil in the foundation pit is soft, the protective measures can be adjusted in a timely manner; and it can protect foundation pits of different specifications, thereby improving the effectiveness and functionality of the support device and making it more convenient for workers to operate.

[0007] Preferably, one end of the screw is fixedly connected to a throttle, and the surface of the throttle is provided with a plurality of anti-slip protrusions.

[0008] The effect achieved by the above components is that the screw can be rotated more conveniently and quickly by setting the throttle, thereby enabling the support rod to press against the support plate more quickly and timely, and improving the ease of use of the support device.

[0009] Preferably, a reinforcing plate is fixedly connected to one side surface of the base plate, and a plurality of evenly distributed reinforcing blocks are fixedly connected to the surface of the reinforcing plate, wherein the cross-section of the plurality of reinforcing blocks is conical.

[0010] The effect achieved by the above components is that, by setting up the reinforcing plates and reinforcing blocks, the base plate can be made more stable when placed on the foundation pit ground, and it is not easy for abnormal shaking to occur, thereby ensuring the limiting and fixing of the support plates on both sides.

[0011] Preferably, a stabilizing plate is fixedly connected to the surface of both stabilizing rods, and two support rods are fixedly connected to both sides of the surface of the stabilizing plate.

[0012] The effect achieved by the above components is that the screw is more stable by setting the stabilizing plate and the support rod, and the device is less prone to shaking, thereby improving the stability and effectiveness of the support device.

[0013] Preferably, a nut is threaded onto the arc surface of the screw, and the nut is located on the arc surface of the screw between the connecting frame and the stabilizing plate.

[0014] The effect achieved by the above components is as follows: by setting the nut, when the support rod is stably compressed and supported by the support plate, the nut rotates and presses against the surface of the connecting frame, so that the screw is not easy to rotate and cause abnormal sliding of the connecting frame, thus ensuring the support effect of the foundation pit.

[0015] Preferably, a fixing device is provided on the surface of the two support plates at the installation position of the support device. The fixing device includes two connecting plates, which are respectively fixedly connected to the clamping plates on the two support plates. The surface of the two connecting plates is provided with mounting holes, and bolts are inserted through the inner wall of the mounting holes. The bolts are threaded to the surface of the support plates.

[0016] The effect achieved by the above components is that the support device is more stable and secure during installation, and is less likely to separate from the support plate, thereby improving the performance and stability of the support device.

[0017] Preferably, a washer, which is a rubber ring, is fitted onto the arc surface of the bolt.

[0018] The effect achieved by the above components is that, by setting the washers, the bolts are more stably fitted when installed on the connecting plate, which makes it less likely for the bolts to rotate and loosen, thus ensuring the stable installation of the support device.

[0019] Preferably, positioning plates are fixedly connected to both sides of the surfaces of the two connecting plates, and the positioning plates are engaged with the surfaces of the support plates.

[0020] The effect achieved by the above components is that the connection strength between the connecting plate and the support plate is further improved by setting the positioning plate, thereby making the installation of the support device more stable and secure.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this utility model, when providing protective support for civil engineering foundation pits, it is possible to conveniently compress and protect both sides of the foundation pit. When the soil in the foundation pit is soft, the protective measures can be adjusted in a timely manner. Furthermore, it can protect foundation pits of different specifications, improving the effectiveness and functionality of the support device and making it more convenient for workers to operate.

Detailed Implementation

[0028] Example 1, such as Figure 1 As shown, a foundation pit support structure for civil engineering includes two support plates 1. A support device 2 is provided on one side of the two support plates 1 that is close to each other, and a fixing device 3 is provided on the surface of the two support plates 1 at the installation position of the support device 2.

[0029] Reference Figure 1 , Figure 2 and Figure 3As shown in this embodiment: the support device 2 includes a connecting frame 21, with support rods 22 rotatably connected to both sides of the surface of the connecting frame 21. Each end of the support rod 22 is secured with a clamping plate 23, which is clamped onto the surface of the support plate 1. A threaded rod 24 is threaded through the surface of the connecting frame 21, and one end of the threaded rod 24 is rotatably connected to a bottom plate 25 installed on the inner wall of the pit. Two stabilizing rods 26 are fixedly connected to the surface of the bottom plate 25, and the two stabilizing rods 26 are slidably connected through the surface of the connecting frame 21. When supporting the foundation pit of a civil engineering project, firstly, the two support plates 1 are respectively attached to the inner walls of both sides of the pit, then the bottom plate 25 is placed at the bottom of the pit, and then... The screw 24 on the movable base plate 25 is displaced and raised by the connecting frame 21 through the limiting action of the stabilizing rod 26. During the displacement of the connecting frame 21, the clamping plates 23 at both ends of the connecting frame 21 on both sides are rotated and clamped onto the surface of the support plate 1. Then, the screw 24 is continuously rotated, which increases the squeezing force of the connecting frame 21. At this time, when protecting and supporting the civil engineering foundation pit, it is convenient to squeeze and protect both sides of the foundation pit. When the foundation pit soil is soft, the protection measures can be adjusted in time. It can also protect foundation pits of different specifications, improve the use effect and functionality of the support device 2, and make it more convenient for workers to operate.

[0030] Reference Figure 1 , Figure 2 and Figure 3 As shown in this embodiment: a handle 27 is fixedly connected to one end of the screw 24. The surface of the handle 27 is provided with several anti-slip protrusions. The handle 27 makes it easier and faster for the screw 24 to rotate, thereby enabling the support rod 22 to press against the support plate 1 more quickly and timely, improving the ease of use of the support device 2. A reinforcing plate 28 is fixedly connected to one side surface of the base plate 25. Several evenly distributed reinforcing blocks 29 are fixedly connected to the surface of the reinforcing plate 28. The cross-section of the reinforcing blocks 29 is conical. The reinforcing plate 28 and the reinforcing blocks 29 make the base plate 25 more stable when it is placed on the pit ground, and it is not easy for abnormal shaking to occur, thereby ensuring the limiting and fixing of the support plates 1 on both sides.

[0031] Reference Figure 1 , Figure 2 and Figure 3As shown in this embodiment: a stabilizing plate 211 is fixedly connected to the surfaces of the two stabilizing rods 26. Two supporting rods 212 are fixedly connected to the two sides of the surface of the stabilizing plate 211. The setting of the stabilizing plate 211 and the supporting rods 212 makes the screw 24 more stable and prevents the device from shaking, thereby improving the stability and performance of the support device 2. A nut 210 is threadedly connected to the arc surface of the screw 24. The nut 210 is located on the arc surface of the screw 24 between the connecting frame 21 and the stabilizing plate 211. With the setting of the nut 210, when the support rod 22 provides stable compression support to the support plate 1, the nut 210 rotates and presses against the surface of the connecting frame 21, thereby preventing the screw 24 from rotating and causing abnormal sliding of the connecting frame 21, thus ensuring the support effect for the foundation pit.

[0032] Reference Figure 1 , Figure 2 and Figure 4 As shown in this embodiment: the fixing device 3 includes two connecting plates 31, which are respectively fixedly connected to the clamping plates 23 on the two support plates 1. The surfaces of the two connecting plates 31 are respectively provided with mounting holes 32. Bolts 33 are inserted through the inner walls of the mounting holes 32 and are threadedly connected to the surface of the support plates 1. When the support device 2 installed on the support plates 1 is reinforced, the bolts 33 are first inserted through the mounting holes 32 on the surface of the connecting plates 31, and the connecting plates 31 are fixedly connected to the clamping plates 23 on the support plates 1. Then, the bolts 33 are rotated to make the bolts 33 threadedly connected to the support plates 1, so that the position of the clamping plates 23 is fixed. At this time, the support device 2 is more stable and firm during installation and is not easy to separate from the support plates 1, thereby improving the use effect and stability of the support device 2.

[0033] Reference Figure 1 and Figure 4 As shown in this embodiment: a washer 35 is fitted on the arc surface of the bolt 33. The washer 35 is a rubber ring. The washer 35 makes the bolt 33 more stable and fits better when it is installed on the connecting plate 31, thus making the bolt 33 less likely to rotate and loosen, thereby ensuring the stable installation of the support device 2. Positioning plates 34 are fixedly connected to both sides of the surface of the two connecting plates 31. The positioning plates 34 are engaged with the surface of the support plate 1. The positioning plates 34 further improve the connection strength between the connecting plate 31 and the support plate 1, thereby making the installation of the support device 2 more stable and firm.

[0034] Working principle: When supporting the foundation pit of a civil engineering project, firstly, two support plates 1 are respectively attached to the inner walls of both sides of the foundation pit. Then, the bottom plate 25 is placed at the bottom of the foundation pit, and the reinforcing blocks 29 on the bottom plate 25 are inserted into the ground of the foundation pit. Then, the screw 24 on the bottom plate 25 is rotated. Because the connecting frame 21 is limited by the stabilizing rod 26, it is displaced and raised under the drive of the screw 24. During the displacement of the connecting frame 21, the clamping plates 23 at both ends of the connecting frame 21 on both sides are rotated and clamped onto the surface of the support plate 1. Then, the screw 24 is continuously rotated to increase the squeezing force of the connecting frame 21. At this time, when providing protective support for the civil engineering foundation pit, the two sides of the foundation pit can be conveniently squeezed and protected. When the foundation pit soil is soft, the protection measures can be adjusted in time. It can also protect foundation pits of different specifications, improve the use effect and functionality of the support device 2, and make it more convenient for workers to operate.

[0035] When reinforcing the support device 2 installed on the support plate 1, firstly, the bolt 33 with the washer 35 is passed through the mounting hole 32 on the surface of the connecting plate 31, and the connecting plate 31 is fixedly connected to the clamping plate 23 on the support plate 1. Then, the bolt 33 is rotated to make the bolt 33 threadedly connected to the support plate 1, so that the position of the clamping plate 23 is fixed. At this time, the support device 2 is more stable and firm during installation, and it is not easy to separate from the support plate 1, thereby improving the use effect and stability of the support device 2.
