Description

Technical Field

[0001] The present invention relates to the technical field of construction equipment, and particularly relates to a detachable drain hole filter element for an I-beam micropile retaining wall on a loess slope. Background Art

[0002] Loess is a special type of soil with high porosity, low shear strength, and is vulnerable to water erosion. Loess slopes are prone to landslides and collapses under the influence of natural and human factors. As the main preventive measure for high slopes against sliding, the groundwater inside the retaining wall cannot be discharged in time, resulting in an increase in the earth pressure borne by the retaining wall, a decrease in overall stability, and an increased risk of slope instability and collapse. Therefore, a sufficient number of drain holes need to be provided in the retaining wall body, and ensuring the normal operation of the drain holes is a key task for high slope anti-sliding.

[0003] In Chinese Patent No. 202410995250.7, the drain device is easily blocked by mud, sand, and garbage. Especially during rainfall, rainwater will carry a large amount of mud and debris into the drain device, causing the drain holes to be blocked, resulting in problems such as the stability of the foundation pit due to the inability of the slope to drain smoothly. Moreover, once blocked, it will cause the accumulated water behind the drain holes to be unable to be discharged smoothly. Therefore, the present invention proposes a detachable drain hole filter element for an I-beam micropile retaining wall on a loess slope to solve the problems existing in the prior art. Summary of the Invention

[0004] In view of the above problems, the object of the present invention is to propose a detachable drain hole filter element for an I-beam micropile retaining wall on a loess slope. This detachable drain hole filter element for an I-beam micropile retaining wall on a loess slope can effectively filter sediment and prevent blockage, thereby ensuring the long-term smoothness of the drain holes, improving the drainage efficiency. By driving the outer rod to move through the mounting block, the outer rod drives the rotating block to move, driving the inner mounting tube to move towards the inner side of the mounting cavity, and performing detachable installation on the inside of the filter element. When not in use, directly rotate the mounting block to install the inner tube, and when replacement is needed, take out the inner tube. Since the filter element can be disassembled, cleaned, and replaced, the risk of the drain hole failing due to blockage is reduced.

[0005] To achieve the object of the present invention, the present invention is realized through the following technical solutions: A detachable water drainage hole filter element for an I-beam micropile retaining wall of a loess slope, comprising a retaining wall, a detachable filter element body, and a disassembly component. A drainage port is provided inside the retaining wall. The detachable filter element body is movably installed inside the drainage port. A disassembly component is arranged on the outer side of the detachable filter element body. The drainage port is blocked by the detachable filter element body, and the detachable filter element body can be disassembled and replaced at any time through the disassembly component. The disassembly component includes a filter element head, an installation inner cavity, an installation inner tube, a rotating block, an outer rod, and an installation block.

[0009] Further improvement lies in that: An outer installation port is provided on the outer side of the retaining wall. Clamping blocks are fixedly installed on both sides of the outside of the detachable filter element body, and the inside of the outer installation port is mutually adapted to the clamping blocks.

[0010] Further improvement lies in that: Ventilation holes are provided on both sides inside the detachable filter element body. Multiple groups of ventilation holes are provided and there are no less than two groups.

[0011] Further improvement lies in that: Multiple groups of threaded grooves are provided inside the detachable filter element body. Threads are provided on the outer side of the rotating block, and the threaded grooves are mutually adapted to the threads on the outer side of the rotating block.

[0012] Further improvement lies in that: Grooves are provided on the outer side of the detachable filter element body. The grooves are arranged on both sides of the detachable filter element body.

[0013] Further improvement lies in that: Sealing gaskets are fixedly installed on the outer side of the filter element head. Multiple groups of sealing gaskets are provided and there are no less than two groups. The size specifications of each group of sealing gaskets are the same.

[0014] A further improvement lies in that: the specification of the detachable filter element body is selected and installed according to the specification of the drain outlet. The detachable filter element body is cylindrical and is adapted to the installation inner tube, and the installation inner tube is installed after the detachable filter element body is installed.

[0015] The beneficial effects of the present invention are as follows: through the mutual cooperation of the filter element head, the installation inner cavity, the installation inner tube, the rotating block, the outer rod and the installation block, the detachable water discharge hole filter element can effectively filter sediment and prevent blockage, thereby ensuring the long-term smoothness of the water discharge hole, improving the drainage efficiency. By driving the outer rod to move through the installation block, the outer rod drives the rotating block to move, driving the installation inner tube to move towards the inner side of the installation inner cavity, and detachably installing the inside of the filter element. When replacement is needed, directly rotate the installation block to install the inner tube, and take out the inner tube when replacement is needed.
