Description

Technical Field

[0001] The utility model relates to the technical field of drainage equipment, in particular to a foundation drainage structure. Background Art

[0002] Soft soil foundation usually refers to a weak soil layer with low strength and high compression. The water permeability of soft soil foundation is very low, and the vertical plane is almost impermeable, which is not conducive to drainage and consolidation. It often has a high pore water pressure, which affects the strength of the foundation. Therefore, in construction projects, soft soil foundations are usually drained and reinforced.

[0003] To solve the above problems, a utility model patent with announcement number CN217758697U in the prior art discloses a soft soil foundation waterproofing and drainage structure, which includes a base and a moving device, wherein the moving device includes a wheel fixedly connected to the bottom of the base, a threaded rod is threadedly inserted into the base, and a hand wheel is fixedly connected to the upper end of the threaded rod, which is above the base, and a support foot is rotatably connected to the lower end of the threaded rod, which is below the base under the support foot, and a plug-in device is provided on the top of the base; the plug-in device includes two limit plates fixedly connected to the top of the base, a lifting plate is slidably connected between the two limit plates, a guide rod is fixedly connected between the limit plate and the base, the middle part of the guide rod is inserted through the lifting plate, and a cylinder is fixedly connected to the top of the lifting plate. The soft soil foundation waterproofing and drainage structure has the advantage that the device can be easily moved to a small area for drainage.

[0004] However, this solution has the following defects: in this solution, the water pumped from the ground cannot be discharged on the spot, and an external device is required to connect the drainage pipe for transportation or storage. The water pump, suction pipe, filter cartridge and other equipment in this solution are all installed on the mounting plate. Each time they are operated, the suction pipe, water pump, drainage pipe and the like rotate synchronously with the filter cartridge, but the angle of the filter cartridge is not necessarily the same, which causes the direction of the drainage pipe to be not necessarily the same. This causes the drainage pipe to be reconnected to the external water delivery equipment before and after each use of this solution, which includes the placement angle of the structure, or the placement angle of the external equipment, reinstallation, disassembly and other issues, which increases the operation steps and affects the construction efficiency.
