Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit support construction, in particular to a quick-detachable connection device for a foundation pit enclosure structure and a concrete waist beam. Background Art

[0002] In construction projects, the connection between the foundation pit retaining structure and the concrete waist beam is a very important link. The traditional connection between the foundation pit retaining structure and the concrete waist beam is usually made by pouring concrete. Although the concrete pouring method can provide strong connection strength and stability, it also has many shortcomings. First, concrete pouring requires a long construction period, and a large amount of manpower and material resources are required during the construction process, which increases the cost of the project. Secondly, once the concrete structure is formed, it is very difficult to dismantle, and heavy machinery is usually required for demolition, resulting in material waste and environmental pollution. In addition, the connection method of concrete pouring lacks flexibility and is difficult to adapt to temporary adjustment needs that may arise in the project. An underground continuous wall and waist beam connection structure in a foundation pit published in an existing patent (Announcement No.: CN217629972U) has at least the following defects exposed during use:

[0003] 1. If the disassembly and assembly functions of the foundation pit retaining structure and the concrete waist beam are not achieved through the mutual cooperation between the structures, the construction process will have to rely on the traditional concrete pouring method. This will lead to an increase in construction complexity, because concrete pouring requires a lot of preparation work and precise construction steps. Material waste will also increase. Concrete pouring is used once and cannot be reused when it is demolished, resulting in a large amount of material waste, which does not meet the requirements of saving resources and environmental protection. Rising costs are another problem. Since more materials and human resources are needed, the construction cost will increase significantly, especially when frequent disassembly and assembly are required. The demolition process will also become more difficult. Once the concrete structure is solidified, the demolition process is cumbersome and time-consuming, and heavy machinery may be required, which increases the difficulty and danger of demolition. Finally, the environmental impact will also increase. The concrete pouring and demolition process will generate a large amount of construction waste and dust, increasing the environmental burden and pollution risk.

[0004] 2. If the function of rapid disassembly and assembly is not achieved by installing fixed blocks, fixed holes, removable limit rods and limit holes, the installation efficiency will be low, because without the design of fixed blocks and limit holes, the connection between the foundation pit retaining structure and the concrete waist beam will require additional fixing measures, which increases the time and complexity of installation. The disassembly and assembly process will also become cumbersome. The lack of removable limit rods and limit holes requires more tools and steps during disassembly, and rapid disassembly and assembly cannot be achieved, which reduces construction efficiency. Operational risks will also increase. The increase in manual operation steps can easily lead to construction errors and safety accidents, increasing the risks in the construction process. The connection may not be stable enough. Without the precise positioning of fixed blocks and limit holes, the connection structure may not be stable enough, affecting the overall construction quality and safety. Finally, the maintenance cost will also increase. The disassembly and assembly process is complicated and time-consuming, which increases the cost of maintenance and replacement of parts, and is not conducive to long-term use and maintenance.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0015] 1. The utility model realizes the disassembly and assembly of the foundation pit retaining structure and the concrete waist beam through the mutual cooperation between the structures, so that it does not need to use concrete pouring and can be reused. Specifically, the utility model designs an ingenious connection device, by setting interlocking connection parts between the foundation pit retaining structure and the concrete waist beam, so that the two can be firmly connected together without using traditional concrete pouring methods. This design not only greatly simplifies the construction process and reduces the demand for construction materials, but also effectively reduces construction costs and time. In addition, since concrete pouring is not required, tedious demolition work is no longer required during disassembly. The foundation pit retaining structure can be separated from the concrete waist beam with simple operations, which is convenient for repeated use, achieving efficient resource utilization and environmental protection goals.

[0016] 2. The utility model realizes the function of quick disassembly and assembly by installing fixed blocks, fixed holes, removable limit rods and limit holes. Specifically, the design of the fixed blocks and limit holes makes the connecting device highly flexible and convenient. During the installation process, it is only necessary to insert the fixed block into the fixed hole, and then insert the removable limit rod from the limit hole and pass through the fixed block. A quick and stable connection can be achieved without the need for additional fixing measures, which greatly improves the construction efficiency. When disassembly is required, only simple tools are needed to dismantle the structure, and the entire disassembly and assembly process is fast and convenient. Such a design not only reduces the complexity of manual operation and improves work efficiency, but also reduces the risk of errors during the construction process, ensuring that the connection between the foundation pit retaining structure and the concrete waist beam is stable and reliable, but also makes the disassembly and assembly process safer and more efficient.
