Description

Technical Field

[0001] The utility model relates to the technical field of civil construction pile foundations, and more specifically, to a supporting pile foundation pit supporting device. Background Art

[0002] Civil engineering refers to the planning, construction and maintenance of all infrastructure related to water, soil and culture. When civil engineering is constructed, a large number of supporting piles are needed. The supporting piles are used as the foundation for engineering construction. The supporting piles buried in the pit are prone to tilt and need to be fixed with supporting piles. The existing supporting pile foundation pit support devices do face a significant challenge in the design and application process: they are often unable to effectively fix supporting piles of different sizes. This limitation is mainly due to the design limitations of the device itself and the lack of sufficient flexibility. Specifically, the existing supporting pile foundation pit support devices usually adopt standardized sizes and structures, which makes them have good adaptability to supporting piles of specific sizes. However, in actual engineering, due to the influence of various factors such as geological conditions, foundation pit size and design requirements, Due to the influence of the size and shape of the supporting pile foundation, there may be large differences. These differences result in the existing support devices often being unable to provide a stable fixing effect when facing supporting pile foundations of different sizes. For example, when the size of the supporting pile foundation is small, the existing support device may be too tight, resulting in loose fixation, and may even cause damage to the supporting pile foundation. On the contrary, when the size of the supporting pile foundation is large, the device may lose its fixing effect due to the inability to fit closely, resulting in serious consequences such as instability or collapse of the foundation pit. In addition, the existing support devices also have deficiencies in adjustment and adaptability. Due to the limitations of the structural design, these devices are often unable to quickly and easily adapt to supporting pile foundations of different sizes, which not only increases the difficulty and cost of construction, but may also affect the progress and quality of the project. Therefore, they need to be improved and optimized. Utility Model Content

[0010] As a preferred technical solution of the utility model,

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. The utility model constructs an extremely stable support structure by using a plurality of connecting long rods (including connecting long rods 1, 2, 3 and 4) in conjunction with round rods 1 and 2, which not only ensures the firmness of the device during the support process, but also gives it excellent compressive resistance. When the foundation pit faces external pressure, such as soil side pressure, groundwater flow impact, etc., these connecting long rods and round rods can work together to form an effective resistance system to effectively disperse and resist external pressure, thereby ensuring the stability and safety of the foundation pit. Compared with traditional devices, the utility model has shown extremely high practicality and applicability by setting a telescopic mechanism and a rotating mechanism, so that no matter how the size and shape of the foundation pit change, or how the size of the supporting pile foundation is different, this new device can find the best supporting position and posture by adjusting the telescopic mechanism and the rotating mechanism, so as to achieve effective fixation of the supporting pile foundation, which not only improves construction efficiency and reduces construction costs, but also ensures the stability and safety of the foundation pit, providing a strong guarantee for the smooth progress of the entire project.

[0013] 2. The utility model makes the connection between the protective plate one and the protective plate two simple and quick through the matching design of the cross block and the cross groove. During installation, it is only necessary to align the cross block of one protective plate with the cross groove of the other protective plate and insert it. No additional fixing tools or complicated operations are required. When disassembly is required, it can be completed quickly. The matching of the cross block and the cross groove not only ensures the firmness of the connection, but also prevents the protective plate from being displaced or tilted when subjected to force to a certain extent, thereby enhancing the structural stability of the entire support device. Compared with traditional devices, since the shapes and sizes of the cross block and the cross groove are precisely designed, the positional relationship between the two protective plates can be ensured to be accurate during connection, which is necessary to ensure the overall effect and safety of the support device, so that the support device can adapt to foundation pits of different sizes and shapes. By adjusting the angle and position between the protective plate one and the protective plate two, it can flexibly cope with various complex foundation pit environments. Due to the simplicity of the connection method, when the protective plate needs to be repaired or replaced, the disassembly and installation work can be completed quickly, thereby reducing the maintenance difficulty and cost.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figures 1 to 5 As shown, the utility model provides a supporting pile foundation pit supporting device, including a protective plate 1, a round rod 1 3 and a round rod 2 4 are arranged on the left side of the protective plate 1, a telescopic mechanism and a rotating mechanism are arranged on the left outer wall of the protective plate 1, the telescopic mechanism includes a connecting long rod 1 2 and a round rod 3 hingedly installed on the left outer wall of the protective plate 1, the connecting long rod 1 2 penetrates the connecting long rod 1 2 and is rotatably connected to the connecting long rod 1 2, the round rod 2 4 penetrates the connecting long rod 3 9 and is rotatably connected to the connecting long rod 3 9, a connecting long rod 4 10 is rotatably sleeved on the outer wall of the round rod 3, the left end of the connecting long rod 4 10 is hingedly installed with a protective plate 2 8, a connecting long rod 2 5 is rotatably sleeved on the outer wall of the round rod 2 4, and the left end of the connecting long rod 2 5 is hinged to the right side of the protective plate 2 8.

[0022] By using a plurality of connecting long rods including connecting long rods 1, 2, 3 and 4 in coordination with round rod 1 3 and round rod 2 4, an extremely stable supporting structure is constructed, which not only ensures the firmness of the device during the supporting process, but also gives it excellent compressive resistance. When the foundation pit faces external pressure, such as soil side pressure, groundwater flow impact, etc., these connecting long rods and round rods can work together to form an effective resistance system to effectively disperse and resist external pressure, thereby ensuring the stability and safety of the foundation pit. Compared with traditional devices, by setting up telescopic mechanisms and rotating mechanisms, it shows extremely high practicality and applicability, so that no matter how the size and shape of the foundation pit change, or how the size of the supporting pile foundation is different, this new device can find the best supporting position and posture by adjusting the telescopic mechanism and the rotating mechanism, so as to achieve effective fixation of the supporting pile foundation, which not only improves construction efficiency and reduces construction costs, but also ensures the stability and safety of the foundation pit, providing a strong guarantee for the smooth progress of the entire project.

[0023] The staff first puts the device into the support pile foundation pit so that the protective plate 1 and the protective plate 2 8 face the inner wall of the support pile foundation pit respectively, and then holds the handle 18 to rotate it, and the handle 18 drives the disc 17 to rotate, and the disc 17 drives the rotating rod 15 to rotate. The rotating rod 15 is threadedly connected with the rectangular block 13, so that by rotating the rotating rod 15, the rectangular block 2 14 is driven to move in the direction of the rectangular block 13, so that through the coordination and adjustment of multiple connecting long rods including connecting long rods 1, 2, 3 and 4 with round rods 1 3 and round rods 2 4, the angle between the protective plate 1 and the protective plate 2 8 is adjusted, so that the protective plate 1 and the protective plate 2 8 are in conflict with the inner wall of the support pile foundation pit, thereby achieving the support purpose.

[0024] Among them, cross blocks 11 are fixedly installed on the tops of the protective plates 1 and 2 8 respectively, and cross grooves 12 are opened on the bottoms of the protective plates 1 and 2 8 respectively, and the cross blocks 11 are adapted to the cross grooves 12.

[0025] The matching design of the cross block 11 and the cross slot 12 makes the connection between the protective plates simple and fast. During installation, it is only necessary to align the cross block 11 of one protective plate with the cross slot 12 of the other protective plate and insert it. No additional fixing tools or complicated operations are required. When disassembly is required, it can be completed quickly. The matching of the cross block 11 and the cross slot 12 not only ensures the firmness of the connection, but also prevents the protective plate from being displaced or tilted when subjected to force to a certain extent, thereby enhancing the structural stability of the entire support device. Compared with traditional devices, since the shapes and sizes of the cross block 11 and the cross slot 12 are precisely designed, the positional relationship between the two protective plates can be ensured to be accurate during connection, which is necessary to ensure the overall effect and safety of the support device, so that the support device can adapt to foundation pits of different sizes and shapes. By adjusting the angle and position between the protective plate 1 and the protective plate 2 8, it can flexibly cope with various complex foundation pit environments. Due to the simplicity of the connection method, when the protective plate needs to be repaired or replaced, the disassembly and installation work can be completed quickly, thereby reducing the difficulty and cost of maintenance.

[0026] When the depth of the supporting pile foundation pit is too deep and exceeds the original vertical height of the protective plate 1 and the protective plate 2 8, the staff can successfully expand the height of the supporting pile foundation pit supporting device by aligning and inserting the specific structure of the two protective plates, namely the cross block 11 and the cross groove 12, to meet the support requirements of the deeper foundation pit.

[0027] Among them, two connecting short rods 27 are rotatably sleeved on the outer wall of the round rod 2 4, and the sides of the two connecting short rods 27 close to each other are hinged to the outer wall of the connecting long rod 1 2, and two connecting short rods 1 6 are rotatably sleeved on the outer wall of the round rod 1 3, and the sides of the two connecting short rods 1 6 close to each other are hinged to the outer wall of the connecting long rod 2 5.

[0028] By hingedly connecting the short connecting rod 1 6 and the short connecting rod 2 7 with the long connecting rod 1 2 and the long connecting rod 2 5 respectively, a stable quadrilateral structure is formed, which can effectively resist external pressure during the support process and ensure the stability and safety of the support device.

[0029] There are two groups of telescopic mechanisms which are symmetrically distributed.

[0030] The symmetrically distributed telescopic mechanism can ensure that the supporting force of the support device is more uniform when supporting the foundation pit, which helps to maintain the stability and safety of the foundation pit and reduce the risk of foundation pit deformation or collapse due to uneven supporting force.

[0031] Among them, the rotating mechanism includes a rectangular block 13 fixedly sleeved on the outer wall of the round rod 1 3, a rectangular block 14 fixedly sleeved on the outer wall of the round rod 2 4, a rotating rod 15 is rotatably installed on the front of the rectangular block 2 14, a threaded groove 16 is opened on the outer wall of the rotating rod 15, the rotating rod 15 passes through the rectangular block 2 14 and the rectangular block 1 13, the rotating rod 15 is rotatably connected to the rectangular block 2 14, and the rotating rod 15 is threadedly connected to the rectangular block 1 13.

[0032] By opening a thread groove 16 on the outer wall of the rotating rod 15 and threading the rotating rod 15 with the rectangular block 1 13 , the positions of the round rod 2 4 and the rectangular block 2 14 can be accurately adjusted by rotating the rotating rod 15 to meet the power requirements of the telescopic mechanism.

[0033] A disc 17 is fixedly mounted on the front of the rotating rod 15 , and a handle 18 is rotatably mounted on the front of the disc 17 .

[0034] By providing a combined design of the disc 17 and the handle 18, the staff can apply force more directly and comfortably when they need to rotate the rotating rod 15. The handle 18 provides a better grip, reduces hand fatigue, and improves work efficiency.

[0035] The working principle and use process of this utility model:

[0036] The staff first puts the device into the support pile foundation pit so that the protective plate 1 and the protective plate 2 8 face the inner wall of the support pile foundation pit respectively, and then holds the handle 18 to rotate it, and the handle 18 drives the disc 17 to rotate, and the disc 17 drives the rotating rod 15 to rotate. The rotating rod 15 is threadedly connected with the rectangular block 13, so that by rotating the rotating rod 15, the rectangular block 2 14 is driven to move in the direction of the rectangular block 13, so that through the coordination and adjustment of multiple connecting long rods including connecting long rods 1, 2, 3 and 4 with round rods 1 3 and round rods 2 4, the angle between the protective plate 1 and the protective plate 2 8 is adjusted, so that the protective plate 1 and the protective plate 2 8 are in conflict with the inner wall of the support pile foundation pit, thereby achieving the support purpose.

[0037] When the depth of the supporting pile foundation pit is too deep and exceeds the original vertical height of the protective plate 1 and the protective plate 2 8, the staff can successfully expand the height of the supporting pile foundation pit supporting device by aligning and inserting the specific structure of the two protective plates, namely the cross block 11 and the cross groove 12, to meet the support requirements of the deeper foundation pit.
