Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a detachable drainage pipe device and a drainage method for a retaining wall for high slope management. Background Art

[0002] In recent years, the main cause of various geological disasters is rainfall. Retaining walls are the main preventive measure for anti-slip of high slopes. The groundwater inside the retaining walls cannot be discharged in time, resulting in increased soil pressure on the retaining walls, reduced overall stability, and increased risk of slope instability and collapse. Therefore, a sufficient number of drainage holes must be set in the retaining wall body, and ensuring the normal operation of the drainage holes is the key task of anti-slip of high slopes.

[0003] In traditional construction methods, the drainage holes and the retaining wall structure are formed at one time. If the drainage holes are blocked in the later stage, they cannot be dredged, or the inner cavity of the drainage pipe is destructively dredged, which can easily cause secondary blockage in a short period of time, is time-consuming, labor-intensive, and cannot achieve good results. Summary of the Invention

[0004] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and propose a detachable drain pipe device for high slope management retaining wall to solve the problem of blockage and damage of the permeable area of ​​the drain pipe and inability to drain water normally.

[0005] In order to solve the above technical problems, the inventors have arrived at the technical solution of the present invention through practice and summary, and the present invention adopts the following technical solution: a detachable drainage pipe device for a retaining wall for high slope management, comprising a retaining wall, the retaining wall is provided with a fixed stainless steel drainage pipe, the interior of the stainless steel drainage pipe is provided with a movably connected detachable drainage pipe device, the top of the detachable drainage pipe device is provided with a fixedly connected pipe wall drilled water hole, the outer wall of the pipe wall drilled water hole is provided with a detachably connected permeable geotextile, the interior of the detachable drainage pipe device is provided with a clearance-matched cleaning device, the top of the cleaning device is provided with an extended spiral drill rod, the tail end of the extended spiral drill rod is provided with a fixedly connected motor, the motor can be detachably connected to the outer surface of the retaining wall, the middle and upper part of the extended spiral drill rod is provided with a spiral piece, the spiral piece is clearance-matched with the internal top end of the detachable drainage pipe device, the end of the detachable drainage pipe device connected to the outer surface of the retaining wall is provided with a protrusion, and the inside of the protrusion is provided with an opening device. It is more convenient to replace the detachable drain pipe device, and it will not be difficult to remove due to a long time. The stainless steel drain pipe is fixed inside the retaining wall and crosses the entire wall. The stainless steel drain pipe needs to cross the retaining wall and needs support, so stainless steel is selected. The inner wall of the stainless steel drain pipe is matched with the outer wall of the detachable drain pipe device. The length of the stainless steel drain pipe and the protective pipe is determined according to the actual thickness of the retaining wall. Many small holes are arrayed at one end of the pipe wall for water permeability. The small holes are to reduce the pressure of the permeable geotextile. Under long-term water flow and squeezing of the permeable geotextile, mud will enter the inside of the detachable drain pipe device. The extended auger rod is the same length as the inner wall of the detachable drain pipe device. The spiral blade on the extended auger rod can be driven by a motor to rotate, which can bring out the leaked soil and reduce blockage.

[0006] The inner surface of the tab coincides with the outer surface of the retaining wall. An opening shaft is provided within the tab, and the opening device includes an opening rod that rotatably engages the opening shaft. The wall-drilled water hole completely penetrates the retaining wall. The wall-drilled water hole array includes a plurality of small water flow holes. The outer wall of the wall-drilled water hole is provided with a detachably connected permeable geotextile. The other end of the wall-drilled water hole is fixedly connected to a protective tube. The opening rod within the tab can rotate 90 degrees within the tab. When the opening rod is rotated 90 degrees, the bottom of the opening rod engages with the outer surface of the retaining wall, bringing the wall-drilled water hole out. The small holes are designed to reduce pressure on the permeable geotextile. The wall-drilled water hole completely penetrates the retaining wall, increasing the area of ​​the water hole and reducing clogging. The permeable geotextile can be removed for replacement or cleaning.

[0007] The cleaning device is loosely matched with the inner wall of the detachable drain pipe device, a spiral blade is provided at the middle and upper part of the extended auger rod, a motor support frame is fixedly connected above the retaining wall, the motor is fixedly connected to the motor support frame, and the top of the detachable drain pipe device is provided with an auger rod fixed bearing that is loosely matched with the top of the extended auger rod. The spiral blade on the extended auger rod can be driven to rotate by the motor, which can bring out the leaked soil and reduce the blockage. The motor can be turned on according to the blockage situation and does not need to be turned on all the time, which reduces energy waste. The top of the extended auger rod is inserted into the auger rod fixed bearing, which can stabilize the extended auger rod. The rotation of the extended auger rod will also cause the auger rod fixed bearing to vibrate slightly, which can increase the water seepage rate of the detachable drain pipe device, and the slight vibration increases the water seepage rate.
