Technical Field

[0001] The utility model relates to the field of housing construction, in particular to a foundation pit maintenance device for housing construction along railway lines. Background Art

[0002] The foundation pit of a housing building is a key link in construction engineering and involves an important part of foundation construction. It requires careful formulation of an excavation plan according to geological and hydrological conditions and the situation of surrounding buildings, including waterproof and drainage measures. Foundation pit excavation can adopt methods such as slope setting or foundation pit wall support to ensure construction safety and stability. According to the depth of the foundation pit and the surrounding environment, the excavation method without support or with support can be flexibly selected. During the construction process, it is necessary to strictly follow the construction drawings and plans, strengthen safety management, and regularly monitor the deformation of the foundation pit and the groundwater level to ensure the smooth progress of the project and ultimately guarantee the safety and stability of the housing building.

[0003] After strict inspection, for the patent with the application number 202321646005.2 - "A Foundation Pit Maintenance Device for Housing Construction", although it innovatively uses a maintenance board and an inclined strut to effectively maintain the inner wall of the foundation pit, there are still some problems. Specifically, the binding firmness between the bottom insertion rod of the inclined strut in this device and the surrounding soil is insufficient, resulting in insufficient overall support force. Therefore, it is necessary to further optimize and improve the support structure of the maintenance board to enhance its stability and support force. Summary of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a foundation pit maintenance device for housing construction along railway lines to solve the technical problem that the bonding strength between the insertion rod and the external soil in the traditional form is limited and its structural support is weak.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A foundation pit maintenance device for housing construction along railway lines, including a maintenance board and a support assembly. The support assembly includes a first support rod, a second support rod, and a cement base. A reinforcement mechanism is arranged inside the first support rod. The reinforcement mechanism includes a telescopic insertion rod. A chute is opened on the surface of the first support rod. The end of the telescopic insertion rod passes through the first support rod through the chute and is fixedly connected with a convex block.

[0006] By adopting the above technical solution, first, by knocking, the telescopic insertion rod moves and inserts into the soil, enhancing the connection between the support structure and the soil. This operation is simple and effective, and can quickly improve the support stability. At the same time, the insertion depth of the telescopic insertion rod is adjustable, and by controlling the feed amount, it can adapt to different soil conditions, ensuring flexibility and practicality.

[0007] Furthermore, the convex block is used to provide a point of action for an external tool to act on the telescopic insertion rod.

[0008] By adopting the above technical solution, the operator can accurately apply force to the telescopic insertion rod. Such a setting simplifies the operation process and improves work efficiency. At the same time, the position of the telescopic insertion rod can be adjusted by the bump, which can ensure the close contact between the support structure and the soil, thereby enhancing the overall stability.

[0009] Furthermore, the bottom end of the telescopic insertion rod is in a pointed conical structure, and one side of the cement base is in an open structure.

[0010] By adopting the above technical solution, the pointed conical structure at the bottom end of the telescopic insertion rod makes it easier for the insertion rod to penetrate into the soil, reduces the resistance during insertion, improves work efficiency, and at the same time reduces the disturbance to the soil, which is beneficial to maintaining the stability of the soil.

[0011] Furthermore, one end of each of the first support rod and the second support rod is rotatably connected to the maintenance plate through a connecting seat.

[0012] By adopting the above technical solution, the rotatable connection enables the support rod to flexibly adjust the angle within a certain range, which can better adapt to different terrains and engineering requirements, and improves the adaptability of the device.

[0013] Furthermore, adjusting handles are provided on the first support rod and the second support rod, and the adjusting handles are used to adjust the lengths of the first support rod and the second support rod.

[0014] By adopting the above technical solution, the adjusting handles enable the staff to easily adjust the lengths of the support rods, so as to adapt to foundation pits of different depths and widths, which greatly improves the applicability and flexibility of the device.

[0015] Furthermore, the other end of the first support rod is rotatably connected to a first mounting plate, and the first mounting plate is fixedly connected to the top surface of the cement base through a threaded shaft rod.

[0016] By adopting the above technical solution, the rotatable first mounting plate enables the first support rod to adjust the angle when necessary to adapt to different shapes and soil conditions of the foundation pit, thereby enhancing the flexibility and adaptability of the device.

[0017] Furthermore, the other end of the second support rod is rotatably connected to a second mounting plate, and the second mounting plate is fixedly connected to one side surface of the cement base through a threaded shaft rod.

[0018] By adopting the above technical solution, the rotatable connection of the second mounting plate enables the second support rod to flexibly adjust the support angle, so as to better adapt to the geometric shape and geological conditions of the foundation pit, and improves the adaptability and stability of the foundation pit support system.

[0019] In summary, the main beneficial effects of the present utility model are as follows:

[0020] The utility model uses a support component and a hammer to strike a bump, so that the telescopic insertion rod is first inserted into the soil, enhancing the connection between the support structure and the soil. At the same time, the insertion depth of the telescopic insertion rod can be adjusted by the feed amount, so that the stability of the support can be adjusted according to the actual situation. In addition, the first support rod and the second support rod cooperate together to further increase the contact area and structural strength between the telescopic insertion rod and the soil, thereby significantly enhancing the overall stability of the foundation pit. This not only makes the foundation pit maintenance work more flexible and reliable, but also greatly improves the construction safety and reduces the risks such as foundation pit collapse.

The reinforcement mechanism 3 includes a telescopic insertion rod 302. A sliding groove 301 is formed on the surface of the first support rod 201. The end of the telescopic insertion rod 302 passes through the first support rod 201 through the sliding groove 301 and is fixedly connected with a convex block 303. First, by knocking, the telescopic insertion rod 302 moves and inserts into the soil, enhancing the connection between the support structure and the soil. This operation is simple and effective, and can quickly improve the support stability. At the same time, the insertion depth of the telescopic insertion rod 302 is adjustable, and by controlling the feed amount, it can adapt to different soil conditions, ensuring flexibility and practicality. Furthermore, the combined action of the first support rod 201 and the second support rod 202 significantly increases the contact area between the telescopic insertion rod 302 and the soil, thereby greatly enhancing the strength of the connection structure. Finally, the combined effect of these improvement measures significantly improves the maintenance effect of the maintenance board 1 on the foundation pit, ensuring construction safety and the stability of the foundation pit.

[0030] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , the convex block 303 is used to provide a point of force for an external tool to act on the telescopic insertion rod 302, enabling the operator to accurately apply force to the telescopic insertion rod 302. Such a setting simplifies the operation process and improves work efficiency. At the same time, by adjusting the position of the telescopic insertion rod 302 through the convex block 303, it can ensure the close contact between the support structure and the soil, thereby enhancing the overall stability. This stability is crucial for preventing the collapse of the foundation pit and protecting the safety of workers. Generally speaking, the convex block 303 not only provides a convenient operation point but also ensures the firm connection between the support structure and the soil, effectively improving the safety and efficiency of foundation pit maintenance.

[0031] Refer to Figure 3 , the bottom end of the telescopic insertion rod 302 is in a pointed cone structure, and one side of the cement base 207 is in an open structure.

The adjustment handles 203 are used to adjust the lengths of the first support rod 201 and the second support rod 202. The adjustment handles 203 enable the staff to easily adjust the lengths of the support rods, thus adapting to foundation pits of different depths and widths. This greatly improves the applicability and flexibility of the device. At the same time, by adjusting the lengths of the support rods, materials can be utilized more effectively, avoiding waste, and ensuring that the support structure closely fits the actual size of the foundation pit, thereby enhancing the stability and safety of the support. The adjustment handles 203 not only facilitate the operation of the staff but also optimize the support effect, improving the overall efficiency and safety of foundation pit maintenance.

[0035] Refer to Figure 2 、 Figure 3 , the other end of the first support rod 201 is rotatably connected to a first mounting plate 205. The first mounting plate 205 is fixedly connected to the top surface of the cement base 207 through a threaded shaft rod. The rotatable first mounting plate 205 enables the first support rod 201 to adjust the angle when necessary to adapt to different shapes and soil conditions of the foundation pit, thereby enhancing the flexibility and adaptability of the device. At the same time, through the fixed connection of the threaded shaft rod to the top surface of the cement base 207, the stability of the support structure is ensured. This connection method is not only firm and reliable but also convenient for installation and disassembly, improving work efficiency. It not only guarantees the stability and safety of the support structure but also provides a flexible adjustment space, making the foundation pit maintenance work more efficient and convenient.

[0036] Refer to Figure 2 、 Figure 3, the other end of the second support rod 202 is rotatably connected to a second mounting plate 206. The second mounting plate 206 is fixedly connected to one side surface of the cement base 207 through a threaded shaft rod. The rotatable connection of the second mounting plate 206 enables the second support rod 202 to flexibly adjust the support angle, thus better adapting to the geometric shape and geological conditions of the foundation pit, improving the adaptability and stability of the foundation pit support system. At the same time, through the fixed connection of the threaded shaft rod to the side surface of the cement base 207, the firmness and reliability of the entire support structure are ensured. This connection method is simple and easy to implement, facilitating quick installation and disassembly by construction workers, thereby improving work efficiency and enhancing the flexibility and stability of the foundation pit support device, providing a safer and more efficient support guarantee for foundation pit construction.
