Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a device for preventing blockage of drainage pipes on slopes. Background Technology

[0002] A slope drainage hole device is a facility used to drain water from a slope. Its principle is to guide the water inside the slope out through drainage pipes, reducing the accumulation of groundwater. This reduces the water pressure inside the slope and the erosion and displacement forces of groundwater on the slope, thereby reducing the impact on the stability of the slope.

[0003] A search revealed a Chinese patent with authorization announcement number CN220620054U, which discloses a slope drainage hole device, including a drainage pipe, a limiting mechanism, and a filter bag. The end section of the drainage pipe inlet is Z-shaped. The filter bag is placed inside the drainage pipe and located at the inlet end of the drainage pipe. The limiting mechanism passes through the drainage pipe and abuts against the end of the filter bag. The inlet end of the drainage pipe is connected to the slope soil.

[0004] Based on the above search results and existing technologies, the following findings were made:

[0005] In existing slope spraying and anchoring construction, if the water in the slope cannot be discharged from the drainage pipe in time, it may lead to deformation and damage of the support structure. The drainage pipe is also prone to being blocked by mud and debris during use, affecting the drainage effect. The problem of drainage pipe blockage is more prominent, especially in areas with high rainfall or complex geological conditions. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model proposes a device for preventing the blockage of slope drainage pipes. The rubber ring on the protective cap is opened, and then the limit button is pressed simultaneously. At this time, the telescopic spring is compressed. The drainage pipe is then inserted into the protective cap, and the telescopic spring returns to its elasticity, squeezing out the movable block and causing the limit button and limit hole to engage, thus limiting and fixing the drainage pipe and the protective cap. The rubber ring is then released, completing the factory assembly. The assembled device is then transported to the site for on-site installation. During installation, the head drainage hole is kept parallel to the ground, and the tail drainage hole is fully inserted into the slope. After installation, spraying and anchoring are carried out.

[0007] The technical solution to achieve the purpose of this utility model is as follows: a device for preventing blockage of slope drainage pipes, including a protective cap, the protective cap having multiple head drainage holes, and also including: an installation groove on the inner wall of the protective cap, a drainage pipe installed in the installation groove, a rubber ring being installed on both the protective cap and the drainage pipe, and multiple tail drainage holes being provided on the drainage pipe.

[0008] In some embodiments, two limiting posts are fixedly connected to the outer circumferential wall of the drain pipe, and movable blocks are slidably connected to the inner walls of the two limiting posts. Limit buttons are fixedly connected to one side of the two movable blocks, and multiple limiting holes are provided on the protective cap. One end of each of the two limit buttons extends out of the limiting hole.

[0009] In some embodiments, a telescopic spring is installed in each of the two movable blocks, and the two ends of the telescopic spring are fixedly connected to the limiting post and the movable block, respectively.

[0010] In some embodiments, a protruding pipe is installed on one side of the drain pipe.

[0011] Compared with existing technologies, the significant advantages of this invention are:

[0012] This invention involves opening the rubber ring on the protective cap and simultaneously pressing the limit button. The telescopic spring is compressed, and then the drain pipe is inserted into the protective cap. The telescopic spring then returns to its elasticity, squeezing out the movable block and engaging the limit button and limit hole to fix the drain pipe and protective cap in place. The rubber ring is then released, completing the factory assembly. The assembled device is then transported to the site for on-site installation. During installation, the head drain hole is kept parallel to the ground, and the tail drain hole is fully inserted into the slope. After installation, spraying and anchoring are performed to ensure continuous and efficient drainage. Even in areas with high sediment content or heavy rainfall, the device can maintain high efficiency for a long time. Furthermore, the high-strength composite material used in the device is wear-resistant and corrosion-resistant, adaptable to harsh environments, and effectively extends the device's service life.

[0013] This invention solves the problem that if water in the slope cannot be discharged from the drainage pipe in time during the existing slope spraying and anchoring construction, it may lead to deformation and damage of the support structure. The drainage pipe is also prone to being blocked by mud and debris during use, which affects the drainage effect. This problem is particularly prominent in areas with high rainfall or complex geological conditions. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0020] This utility model provides an improved device for preventing blockage of slope drainage pipes. The technical solution of this utility model is as follows:

[0021] Example 1:

[0022] like Figure 1 As shown, a device for preventing blockage of slope drainage pipes includes a protective cap 1 with multiple head drainage holes 4 and an installation groove on the inner wall of the protective cap 1. A drainage pipe 3 is installed in the installation groove. A rubber ring 2 is installed on both the protective cap 1 and the drainage pipe 3. Multiple tail drainage holes 5 are provided on the drainage pipe 3. Through the arrangement of the protective cap 1 and the drainage pipe 3, continuous and efficient drainage of the drainage pipe 3 can be achieved.

[0023] Example 2:

[0024] like Figure 2 As shown in the second embodiment, two limiting posts 6 are fixedly connected to the outer circumferential wall of the drain pipe 3. Movable blocks 7 are slidably connected to the inner walls of the two limiting posts 6. Limiting buttons 8 are fixedly connected to one side of the two movable blocks 7. Multiple limiting holes 9 are provided on the protective cap 1. One end of each of the two limiting buttons 8 extends out of the limiting hole 9. By setting the limiting buttons 8 and the limiting holes 9, it is convenient to limit and fix the drain pipe 3 and the protective cap 1, and at the same time, it is convenient to adjust their length.

[0025] like Figure 2 As shown, in the second embodiment, a telescopic spring 10 is installed in each of the two movable blocks 7. The two ends of the telescopic spring 10 are fixedly connected to the limiting post 6 and the movable block 7, respectively. The setting of the telescopic spring 10 facilitates the reciprocating motion of the movable block 7.

[0026] like Figure 2 As shown, in the second embodiment, a protruding pipe 11 is installed on one side of the drain pipe 3; the protruding pipe 11 facilitates the collection of water flow and also facilitates the protection of the limiting post 6.

[0027] The specific working method is as follows: When using, first open the rubber ring 2 on the protective cap 1, and then press the limit button 8 at the same time. At this time, the telescopic spring 10 is in a compressed state. Then, insert the drain pipe 3 into the protective cap 1. The telescopic spring 10 restores its elasticity and squeezes out the movable block 7, which drives the limit button 8 and the limit hole 9 to cooperate, so that the drain pipe 3 and the protective cap 1 are limited and fixed. Then, release the rubber ring 2 to complete the factory assembly work. Transport the installed device to the site and then install it on site. During installation, keep the head drain hole 4 parallel to the ground and the tail drain hole 5 fully inserted into the slope. After the installation is completed, spray anchoring work is carried out to achieve continuous and efficient drainage of the drain pipe 3. In areas with more silt or a surge in rainfall, the device can still maintain efficient use for a long time. In addition, the high-strength composite material used in the device is wear-resistant and corrosion-resistant, adaptable to harsh environments, and effectively extends the service life of the device.

[0028] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
