Description
Technical Field
[0001] This application relates to the technical field of sewage pipe network construction, and particularly to a foundation pit support structure for a sewage pipe network. Background Art
[0002] With the development of the economy and society, the construction technology of municipal sewage pipe networks has become an important part of urban infrastructure construction. In recent years, significant progress has been made in the construction technology of municipal pipelines in China. In particular, the open-cut pipeline construction technology, that is, the open excavation construction technology, has been widely applied. The foundation pit support structure not only needs to ensure construction safety but also has sufficient stability and adaptability to cope with changing geological conditions and evolving environmental requirements. A reasonable foundation pit support plan can not only effectively guarantee the safety of construction personnel but also improve the overall quality of the project and shorten the construction period.
[0003] In practical applications, common foundation pit support technologies mainly include methods such as steel sheet pile support, soil nail wall support, and diaphragm wall support. Steel sheet pile support provides support by driving steel sheet piles into the side wall of the foundation pit; soil nail wall support involves driving soil nails into the soil mass and reinforcing with a steel mesh to form a stable structure; diaphragm wall support relies on a continuously cast underground wall to protect and support the side wall of the foundation pit.
[0004] Regarding the above-related technologies, the above support schemes meet the requirements of foundation pit construction to a certain extent, but there are still some problems in the actual operation process. Especially when facing complex geological conditions, the support structures in the existing technologies often suffer from insufficient stability. Particularly in soft soil layers and high water table areas, it is easy to cause the failure or deformation of the support structure, thus affecting the quality and safety of the entire project. Utility Model Content
[0005] In order to improve the problem of insufficient stability of the support structure, this application provides a foundation pit support structure for a sewage pipe network.
[0006] A foundation pit support structure for a sewage pipe network provided by this application adopts the following technical solution:
[0007] A foundation pit support structure for a sewage pipe network includes a support assembly and a plurality of support components. The support assembly includes a plurality of support baffles and a plurality of connecting seats. The plurality of support baffles and the plurality of connecting seats can be spliced into a rectangular frame, and the side wall of the rectangular frame can be attached to the side wall of the foundation pit;
[0008] Multiple said support components are all located within the rectangular frame. The support component includes a telescopic member and a support member. The telescopic member includes a second fixed rod. The support member includes a support rod. The second fixed rod is located between two facing support baffles. One end of the second fixed rod is connected to one of the support baffles, and the other end is connected to one end of the support rod. The other end of the support rod is connected to the other support baffle. The second fixed rod and the support rod are coaxially arranged.
[0009] By adopting the above technical solution, when it is necessary to support the foundation pit, first, according to the size of the foundation pit, select an appropriate number of support baffles, splice the support baffles and the connecting seats into a rectangular frame, lift the rectangular frame into the foundation pit by a hoisting mechanism, and make the rectangular frame fit the side wall of the foundation pit. Subsequently, take out the support component, connect the second fixed rod to the designated support baffle, and then connect the support rod to the second fixed rod and the support baffle respectively according to the construction requirements to support the support baffle, so as to realize the support of the foundation pit. The second fixed rod in the telescopic member is connected between two facing support baffles. The second fixed rod and the support rod are coaxially arranged and connected to the support rod, realizing the stable support of the support baffle. Compared with the related technology, in this application, a rectangular frame is spliced by multiple support baffles and connecting seats, and the side wall of the rectangular frame fits the side wall of the foundation pit, enhancing the stability and adaptability of the support structure, effectively improving the stability of the support structure under complex geological conditions, providing strong support for the foundation pit construction, and the position of the support component can be adjusted as needed to adapt to the support requirements at different depths, which is beneficial to improving the problem of insufficient stability of the support structure.
[0010] In a specific feasible embodiment, the telescopic member further includes a first fixed rod and a bolt. One end of the first fixed rod is connected to the support baffle. One end of the second fixed rod is inserted into the other end of the first fixed rod and can slide along the length direction of the first fixed rod within the first fixed rod. The bolt is used to fix the first fixed rod and the second fixed rod.
[0011] The support member further includes a fixing plate, a screw rod, a guiding plate, a guiding rod and a detector for detecting the internal stress of the foundation pit. One end of the support rod close to the second fixed rod is fixed to the fixing plate. The screw rod is rotatably connected to the side of the fixing plate away from the support rod. One end of the screw rod is located in the middle of the fixing plate, and the other end is inserted into the second fixed rod. The second fixed rod is threadedly connected to the screw rod. The second fixed rod reciprocates along the length direction of the screw rod on the screw rod. The guiding plate is coaxially fixed to one end of the second fixed rod. One end of the guiding rod is fixed to the fixing plate, and the other end passes through the guiding plate. The guiding plate is slidably connected to the guiding rod. The detector is fixed to the support baffle.
[0012] By adopting the above technical solution, when it is necessary to support the foundation pit, place the rectangular frame in the foundation pit, connect the first fixing rod to the designated support baffle, and then connect the support rod to the designated support baffle. The operator rotates the screw rod, which can drive the second fixing rod to move, thereby adjusting the length of the support assembly to adapt to the sizes of different foundation pits. At the same time, the detector can realize the real-time monitoring of the internal stress of the foundation pit. The data is uploaded to the monitoring center through the data acquisition unit. The monitoring center analyzes and processes the data and feeds back the analysis results to the construction personnel. The operator only needs to rotate the first screw rod for adjustment, enhancing the adaptability and stability of the foundation pit support structure.
[0013] In a specific feasible implementation, it further includes a fixing component. The fixing component includes a plurality of fixing members and four inserting members. A through groove is formed in the connecting seat.

During the insertion process of the inserting member, the inserting member can drive the fixing rod to move, and the fixing rod slides towards the side away from the inside of the connecting seat until the fixing rod is inserted into the side wall of the foundation pit. When it is necessary to take out the rectangular frame, take out the inserting member, which is convenient for the separation of the fixing rod from the foundation pit. The multiple fixing members of the fixing component can stably fix the rectangular frame on the side wall of the foundation pit, enhancing the overall stability of the foundation pit support structure. The fixing rod is inserted into the side wall of the foundation pit, enabling the fixing rod to be firmly fixed on the side wall of the foundation pit, improving the stability of the support structure.
