Abstract
Description
Technical Field
[0001] The utility model relates to the field of retaining wall anti-blocking and silting, in particular to a retaining wall anti-blocking and silting drainage system. Background Art
[0002] At present, in order to reduce the impact of backwater pressure on the stability of the wall, highway retaining walls are equipped with drainage structures to discharge the water behind the wall. Usually, the drainage structure is a drainage hole set on the retaining wall, and the general arrangement of the drainage holes is a plum blossom arrangement. However, as the service time increases, the pores of the backfill material behind the wall will gradually fill up, and the water flowing into the drainage holes will carry mud and sand, and some of the mud and sand will accumulate in the drainage holes. In the long run, the drainage holes will be blocked and lose the ability to discharge the water behind the wall. The water pressure behind the wall continues to increase, which greatly reduces the safety of the retaining wall during its service life, and also reduces the economic applicability of the retaining wall to a certain extent. Therefore, there is still room for improvement. Utility Model Content

[0031] The following is combined with Figure 1-5 This application is described in further detail.
[0032] The present application discloses a drainage system for preventing siltation and preventing blockage of retaining walls. Figure 1 as well as Figure 2The drainage system for preventing siltation and desilting of retaining walls includes a drainage hole 11, a water collecting pipe 2 and a filter screen 22. The drainage hole 11 is opened on the retaining wall 1. The two ends of the drainage hole 11 are respectively located on the wall surface and the back of the retaining wall 1. There are two rows of drainage holes 11. The two rows of drainage holes 11 are distributed along the height direction of the retaining wall 1, and each row of drainage holes 11 has six drainage holes. The back of the retaining wall 1 is also integrally cast with a supporting groove 12. There are two supporting grooves 12. The two supporting grooves 12 are distributed along the height direction of the retaining wall 1, and the two supporting grooves 12 are respectively opposite to the two rows of drainage holes 11. The length direction of the supporting groove 12 is consistent with the length direction of the retaining wall 1, and the middle position of the supporting groove 12 along the length direction is higher than the two ends of the supporting groove 12. The water collecting pipe 2 is placed in the supporting groove 12. The back of the retaining wall 1 is also fixed with a connecting piece for connecting the drainage hole 11 and the water collecting pipe 2. In this embodiment, the connecting piece is a tee pipe 4 pre-buried on the back of the retaining wall 1. One end of the tee pipe 4 is located in the drainage hole 11 and connected to the drainage hole 11. The end of the water collecting pipe 2 is passed through the tee pipe 4, so that the water collecting pipe 2 can be detachably installed on the tee pipe 4. The tee pipe 4 connects the drainage hole 11 and the water collecting pipe 2.
[0033] Figure 1 , Figure 3 as well as Figure 5 The pipe wall of the water collecting pipe 2 is provided with a plurality of water collecting holes 21, so that the water in the soil behind the retaining wall 1 flows into the water collecting pipe 2 through the water collecting holes 21, and flows to the drainage holes 11 through the tee pipe 4, and is discharged from the retaining wall 1 through the drainage holes 11. The outer wall of the water collecting pipe 2 is covered with a filter screen 22, and the filter screen 22 is used to filter large-volume particles in the water flowing to the water collecting holes 21, so as to prevent large-volume particles from flowing into the water collecting pipe 2 and easily clogging the water collecting pipe 2. A gravel layer 13 is laid in the supporting groove 12, and the gravel layer 13 wraps the water collecting pipe 2, so that the gravel layer 13 further filters large-volume particles in the water flowing to the water collecting holes 21 and protects the filter screen 22.
[0034] Reference Figure 3 as well as Figure 4 The inner wall of the drainage hole 11 is also fixed with a fixing member 3 and a traction line 5 detachably mounted on the fixing member 3. In this embodiment, the fixing member 3 includes a fixing rod 31, a fixing ring 32 and a fixing bolt 33. The fixing rod 31 is pre-buried in the inner wall of the drainage hole 11. The fixing rod 31 is located at one end of the drainage hole 11 close to the wall surface of the retaining wall 1. The fixing ring 32 is fixed to the fixing rod 31, and the fixing bolt 33 is threadedly connected to the fixing ring 32. The traction line 5 is passed through the fixing ring 32. The traction line 5 can be fixed to the fixing member 3 by tightening the fixing bolt 33 until the fixing bolt 33 and the fixing ring 32 clamp the traction line 5. The two ends of the traction line 5 are respectively fixed to the fixing members 3 in the two drainage holes 11, and the traction line 5 is located in the drainage hole 11, the tee pipe 4 and the water collecting pipe 2.
[0035] Reference Figure 3 as well as Figure 4 A connecting sleeve 51 is also fixed to the end of the traction line 5, and the water collecting pipe 2 can also be detachably installed with a cleaning part for cleaning the water collecting pipe 2 and the drainage hole 11. In this embodiment, the cleaning part is a sponge ball 6 threadedly connected to the connecting sleeve 51, and the sponge ball 6 is fixed with two connecting screws 61, which are threadedly connected to the connecting sleeve 51, so that the sponge ball 6 can be detachably installed on the traction line 5, thereby making the sponge ball 6 detachable and installed in the water collecting pipe 2 and the drainage hole 11.
[0036] The implementation principle of a drainage system for preventing siltation and preventing blockage of a retaining wall in the embodiment of the present application is as follows:
[0037] The water in the soil behind the retaining wall 1 is filtered by the gravel layer 13 and the filter screen 22, flows into the drainage hole 11 through the water collecting hole 21, and is discharged from the retaining wall 1 through the drainage hole 11, thereby reducing the blockage of the drainage structure of the retaining wall 1.
[0038] When it is necessary to clean the water collecting pipe 2 and the drainage hole 11, first install the next traction line 5 on the traction line 5 through the connecting sleeve 51 and the connecting screw 61, then loosen the fixing bolt 33, remove the two ends of the current traction line 5 from the fixing ring 32, and then thread the other connecting screw 61 of the sponge ball 6 onto the connecting sleeve 51 at one end of the current traction line 5, and then pull the other end of the traction line 5 to pull the sponge ball 6 into the drainage hole 11, the tee pipe 4 and the water collecting pipe 2, so as to clean the drainage hole 11, the tee pipe 4 and the water collecting pipe 2.
[0039] After the drain hole 11, the tee pipe 4 and the water collecting pipe 2 are cleaned, the sponge ball 6 is removed from the traction line 5, and then the current traction line 5 is inserted into the fixing ring 32, and then the fixing bolt 33 is tightened to fix the current traction line 5.
[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
