Abstract
Description
Technical Field
[0001] This application belongs to the technical field of slope construction, and particularly relates to a clogging-proof slope drain pipe and its construction method. Background Art
[0002] With the increasing development of construction projects, slope projects can be seen everywhere in various engineering projects. The safety and stability of slope support are very important. Since water damage is fatal to the stability of the slope structure, drain pipes are usually set on the slope support during slope support to timely drain the water in the soil body after slope support through the drain pipes, avoid the influence of water damage, and increase the stability of slope support.
[0003] The construction method of the existing drain pipe is as follows: First, use a drill to drill a hole at the designed installation position of the drain pipe, use a perforated pvc pipe as the main body of the drain pipe, and then insert the pvc pipe wrapped with non-woven fabric into the drilled hole to play the role of draining water, that is, the installation of the drain pipe is completed.
[0004] However, the construction method of the existing drain pipe has the following deficiencies: 1. When the drain pipe is inserted into the drilled hole, the non-woven fabric wrapped outside is easily damaged by the friction of the hole wall, resulting in a sharp decline in the drainage effect of the drain pipe. And because the aperture of the water-permeable hole of the drain pipe is small, it may even cause the holes of the pvc pipe to be blocked by the soil body and unable to effectively drain the water in the soil body, affecting the support safety of the slope; 2. After the drain pipe is installed, since the non-woven fabric is in direct contact with the soil body and the pores on the non-woven fabric are small, the soil body is easy to block the pores of the non-woven fabric, reducing the drainage effect and affecting the support safety of the slope.
[0005] Therefore, a construction method of a drain pipe that does not damage the non-woven fabric during installation and reduces blockage during use is needed. Summary of the Invention
[0006] The purpose of this application is as follows: This application provides a clogging-proof slope drain pipe and its construction method, which is applied to the installation of the drain pipe in the slope drain hole to solve the problem that the drain pipe is easily blocked during the construction of the existing slope shotcrete support.
[0007] The purpose of this application is achieved through the following technical solutions:
[0008] A clogging-proof slope drain pipe includes a slope soil body, and an inclined drain pipe body is provided on the slope soil body. The inner end of the drain pipe body is inserted into the slope soil body, and the outer end of the drain pipe body extends out of the slope soil body. The drain pipe body is sequentially provided with a fine stone water filtration layer, an inner filter water plate, a sponge water filtration layer, and an outer filter water plate from the inside to the outside.

[0014] Further, the inner water filtration plate and the outer water filtration plate are plastic plates with water filtration holes, and the inner water filtration plate and the outer water filtration plate are detachably fixed inside the drain pipe body.

[0016] Further, a shotcrete surface is provided on the slope surface of the slope soil body, and the outer end of the drain pipe body extends out of the shotcrete surface.

[0021] Step S04, shotcreting: Performing shotcreting operation on the slope surface of the slope soil body.
[0022] Further, in step S01, according to the construction drawings, lay out the position of the drain pipe body on the slope soil body, move the drill to its position, and keep the drill inclined along the hole - forming angle. Then start the drill to make the drill bit penetrate into the slope soil body. The drill cuttings are stored in the soil bin of the drill bit. When the drill bit penetrates to the set depth, stop drilling and form the hole.
[0023] Further, in step S03, use transparent tape to block the pipe orifice at the outer end of the drain pipe body.
[0024] This application combines the construction technology of slope drainage holes to optimize the design concept of traditional drain pipes, and designs an anti-blocking slope drain pipe and its construction method to ensure the normal operation of the drainage function of the drain pipe during the use of the slope.

Brief Description of the Drawings
[0032] Figure 1 It is a structural schematic diagram of this application.
[0033] In the figure: 1-slope soil body, 2-drain pipe body, 3-fine stone filter layer, 4-inner filter plate, 5-sponge filter layer, 6-outer filter plate, 7-sprayed concrete surface, 201-percolation pipe section, 202-direct penetration pipe section. Specific Embodiments
[0034] The following non-limiting embodiments are used to illustrate this application.
[0035] Embodiment 1
[0036] Refer to Figure 1 As shown, an anti-blocking slope drain pipe includes a slope soil body 1, a drain pipe body 2, a fine stone filter layer 3, an inner filter plate 4, a sponge filter layer 5, an outer filter plate 6 and a sprayed concrete surface 7.
[0037] An inclined drain pipe body 2 is provided on the slope soil body 1 to ensure that the accumulated water in the pipe flows downward. The inner end of the drain pipe body 2 is inserted into the slope soil body 1, and the outer end of the drain pipe body 2 extends out of the slope soil body 1, so as to drain the accumulated water in the slope soil body 1 to the outside of the slope.
[0038] The drain pipe body 2 is successively provided with a fine stone water filtration layer 3, an inner side water filtration plate 4, a sponge water filtration layer 5 and an outer side water filtration plate 6 from the inside to the outside. The water in the slope soil body enters the fine stone water filtration layer through the drain pipe body, then enters the sponge water filtration layer through the inner side water filtration plate, and finally flows out through the outer side water filtration plate into the long straight pipe section.
[0039] That is, this drain pipe optimizes the non-woven fabric wrapped outside the traditional drain pipe. The sponge water filtration layer and the fine stone water filtration layer of the drain pipe are used to replace the non-woven fabric wrapped outside the traditional drain pipe. The pores of the fine stone water filtration layer are much larger than those of the non-woven fabric, realizing preliminary water filtration and drainage, and then secondary water filtration and drainage through the sponge water filtration layer. The drain pipe is not easy to be blocked during use.
[0040] The inclination angle of the drain pipe body 2 is 10-20°, preferably 15°, to ensure the self-flow of the water inside the pipe under gravity. The drain pipe body 2 is made of PVC material, which is strong and durable when buried in the soil. At the same time, the cost is low and it is easy to process and manufacture.
[0041] The drain pipe body 2 includes a filtration pipe section 201 at the inner end and a straight-through pipe section 202 at the outer end. The filtration pipe section 201 is connected to the straight-through pipe section 202. Preferably, the filtration pipe section 201 is connected to the straight-through pipe section 202 by threads, which is convenient for the connection and assembly of the two pipe sections and is also convenient for arranging each water filtration layer therein.
[0042] The filtration pipe section 201 has a structure with a closed inner end and an open outer end. The pipe wall and the rear end sealing plate of the filtration pipe section 201 are both provided with water permeable holes, and the aperture of the water permeable holes is much larger than that of the non-woven fabric, which can greatly reduce the blockage of sand and soil in the water permeable holes and ensure the passage and penetration of seepage.
[0043] A fine stone water filtration layer 3 is provided inside the filtration pipe section 201. The density of the traditional non-woven fabric is small, and it is easy to be blocked when directly contacting the soil body, especially fine sand. This drain pipe uses the fine stone water filtration layer as the first filtration layer, and its pores are much larger than those of the non-woven fabric, which is equivalent to filtering the sand and soil once and greatly alleviating the blockage problem caused by sand and soil.
[0044] The straight-through pipe section 202 has a structure with both inner and outer ends open, preferably a long straight pipe section. The straight-through pipe section 202 is provided with an inner side water filtration plate 4, a sponge water filtration layer 5 and an outer side water filtration plate 6 inside. The water filtration plate has a certain water filtration and seepage effect, and at the same time limits the fine stone water filtration layer 3 at the inner end and the sponge water filtration layer 5 in the middle to ensure the stability of the overall structure. The pores of the sponge water filtration layer 5 are small, and after the first filtration, secondary fine filtration is carried out.
[0045] The inner water filter plate 4 and the outer water filter plate 6 are plastic plates with water filter holes. The inner water filter plate 4 and the outer water filter plate 6 are detachably fixed in the drain pipe body 2. Preferably, the water filter plates are fixed by threads to achieve the disassembly function of the water filter plates from the outside. If the inside of the drain pipe is blocked, the water filter plates can be removed from the outside and the sponge water filter layer can be replaced, thus solving the problem of blockage of the drain pipe.
[0046] The thickness of the fine stone water filter layer 3 is 150 - 250 mm, preferably 200 mm. The thickness of the inner water filter plate 4 and the outer water filter plate 6 is 5 - 15 mm, preferably 10 mm. The thickness of the sponge water filter layer 5 is 50 - 110 mm, preferably 80 mm. The total length of the drain pipe body 2 is 400 - 800, preferably 600 mm, to meet specific construction requirements.
[0047] The slope surface of the slope soil body 1 is provided with a shotcrete surface 7. The outer end of the drain pipe body 2 extends out of the shotcrete surface 7, and the shotcrete surface 7 is used to reinforce the slope surface.
[0048] Embodiment 2
[0049] Reference Figure 1 As shown, a construction method of an anti-blocking slope drain pipe uses the anti-blocking slope drain pipe of Embodiment 1 and further includes the following steps: Step S01, drilling holes with a drill: Use a drill to perform hole-forming operations for drain holes on the slope soil body 1.
[0050] In Step S01, according to the construction drawings, lay out the position of the drain pipe body 2 on the slope soil body 1, move the drill into position, and keep the drill inclined along the hole-forming angle. Then start the drill to make the drill bit drill into the slope soil body 1. The drill cuttings are stored in the soil bin of the drill bit. When the drill bit drills to the set depth, stop drilling and form a hole.
[0051] Step S02, installing the pipe body: Install the drain pipe body 2 into the drain hole.
[0052] Step S03, fixing the pipe body: Fix the outer end of the drain pipe body 2 and seal the pipe orifice at the outer end of the drain pipe body 2 to prevent the shotcrete from blocking the pipe body.
[0053] In Step S03, seal the pipe orifice at the outer end of the drain pipe body 2 with transparent tape.
[0054] Step S04, shotcreting: Perform shotcreting operations on the slope surface of the slope soil body 1.
