Description

Technical Field

[0001] The utility model relates to the technical field of building drainage devices, in particular to an anti-blocking inclined drainage device. Background Art

[0002] When excavating slopes and pit walls in an environment with groundwater, draining groundwater from the soil of the slopes and pit walls is an important means to improve soil stability. Among them, the upward-inclined drainage holes are a major method for draining deep water from the slopes and pit walls. However, the commonly used "PVC drainage pipe drilling and geotextile wrapping" method has a series of problems such as low water filtration capacity, easy clogging, and difficult construction of the anti-filter bag at the end of the pipe. In addition, under the influence of strong soil pressure, the drainage pipe is prone to flattening and damage, resulting in poor workability. Therefore, it is necessary to use an upward-inclined drainage pipe to improve the overall strength of the drainage pipe and the water filtration effect of the slope groundwater.

[0003] Based on this, the inventor has designed an anti-clogging inclined drainage device to solve at least one of the above problems, and thus proposed the present application. Utility Model Content

[0004] The purpose of this application is to provide an anti-clogging inclined drainage device to solve the problems of clogging, poor drainage effect, and easy flattening and damage of the pipes in the current use of PVC drainage pipes drilled around geotextiles.

[0005] In order to solve the above technical problems, the utility model adopts the following solutions:

[0006] The present application provides an anti-blocking inclined drainage device, comprising a drainage pipe body for being obliquely inserted into a slope, and a water filtering sandbag built into the drainage pipe body, wherein:

[0007] The main body of the drainage pipe is also provided with a plurality of through holes distributed outside the water filtering sandbag.

[0008] Preferably, the drain pipe body is provided with a plurality of annular grooves arranged along the axial direction of the drain pipe body;

[0009] It also includes an elastic buckle located in the drain pipe body and matched with the annular groove.

[0010] Preferably, the annular groove includes an annular limiting wall for limiting the elastic buckle, and an adjusting slope for adjusting the position of the elastic buckle toward the side close to the water filter sandbag, and the angle between the adjusting slope and the axis of the drainage pipe ranges from 15° to 60°.

[0011] Preferably, the drainage pipe body section at the periphery of the water filter sandbag is divided into a water inlet hole array area and a water outlet pipe groove area along the circumferential direction, and the through holes are evenly distributed in the water inlet hole array area.

[0012] Preferably, the central angle corresponding to the water inlet hole array area is 180° to 270°.

[0013] Preferably, one end of the drain pipe body is an inclined opening, and the end extending outward from the inclined opening is located on the same side of the drain pipe body as the water outlet pipe groove area.

[0014] Preferably, the distance between the oblique opening and the annular groove is at least 20 cm.

[0015] Preferably, the drainage pipe body is made of PVC material.

[0016] Preferably, the diameter of the drain pipe body ranges from 5 cm to 10 cm.

[0017] Preferably, the water filtering sandbag is in a cylindrical shape that matches the drainage pipe body.

[0018] Beneficial effects of the utility model:

[0019] 1. Compared with the outsourcing geotextile filtration in the prior art, the built-in water filter sandbag method can greatly improve the drainage efficiency and reduce blockage. It can achieve the effect of quickly and continuously draining the water from the slope and pit wall, thereby achieving the purpose of quickly reinforcing the slope.

[0020] 2. The overall structure is simple, the adaptability is strong, the water filtration and drainage effects are good, and the service life is long.

[0021] 3. The materials used are extremely durable. The built-in water filter sandbags can not only filter, but also avoid the drainage pipe body from being flattened as much as possible. The compressive strength of the structure is relatively high. Therefore, the spacing between the drainage holes on the slope can be appropriately increased, the number of drainage holes can be reduced, and the stability of the slope can be improved, which can produce certain safety and economic benefits.

[0022] Fourth, by setting the annular groove and elastic buckle, the water filter sand bag will not move out of the drain pipe body under normal adaptation conditions. When the filtering capacity of the water filter sand bag is reduced, the entire drain pipe body can be pulled out, and then the water filter sand bag in the drain pipe body can be pushed out and replaced, which makes maintenance convenient and simple.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0033] like Figures 1 to 5 As shown, this embodiment provides an anti-blocking inclined drainage device, including a drainage pipe body 1 for being obliquely inserted into a slope, and a water filtering sandbag 2 built into the drainage pipe body 1.

[0034] in:

[0035] The drainage pipe body 1 is also provided with a plurality of through holes 11 distributed outside the water filtering sandbag 2 .

[0036] The present application embeds and fixes the water filter sandbag 2 inside the drainage pipe body 1. Compared with the original method of wrapping with geotextile, the installation of the water filter sandbag 2 for filtering is simpler and more convenient when replacing the water filter sandbag 2 later. At the same time, there is no filtering geotextile blocking the through hole 11 of the drainage pipe body 1, and it is not easy to be blocked. In addition, the method of embedding the water filter sandbag 2 can improve the compressive performance of the drainage pipe body 1 and reduce the possibility of the drainage pipe body 1 being crushed.

[0037] In some preferred exemplary embodiments, the drain pipe body 1 is provided with a plurality of annular grooves 12 arranged along the axial direction of the drain pipe body 1;

[0038] It also includes an elastic buckle 3 located in the drain pipe body 1 and adapted to the annular groove 12. By setting a plurality of annular grooves 12 and elastic buckles 3, in this application, the shape of the elastic buckle 3 is U-shaped. In some embodiments, elastic buckles 3 of other shapes can also be used. The purpose is to limit the water filter sandbag 2 in the drain pipe body 1 from sliding out. The technicians can set it according to their needs. In this embodiment, a plurality of annular grooves 12 are provided, and the position of the elastic buckle 3 can be adjusted, thereby adjusting the distance between the water filter sandbag 2 and the water outlet end of the drain pipe body 1.

[0039] In some preferred exemplary embodiments, Figure 1 As shown, the annular groove 12 includes an annular limiting wall 121 for limiting the elastic buckle 3, and an adjusting slope 122 for adjusting the position of the elastic buckle 3 to the side close to the water filter sandbag 2. The angle between the adjusting slope 122 and the axis of the drain pipe ranges from 15° to 60°. In this embodiment, the angle between the adjusting slope 122 and the axis of the drain pipe is 30°. In some embodiments, angles of 20°, 40°, etc. may also be used, which will not be given as examples. By setting the adjusting slope 122, when the position of the water filter sandbag 2 needs to be adjusted, it is only necessary to use a small diameter rod to push the elastic buckle 3 to push the position of the elastic buckle 3. There is no need to pull the entire drain pipe body 1 out of the hole of the slope for adjustment, which can facilitate the adjustment of the position of the water filter sandbag 2.

[0040] In some preferred exemplary embodiments, the drainage pipe body 1 on the outer periphery of the water filter sandbag 2 is divided into a water inlet hole array area and a water outlet pipe groove area along the circumferential direction, and the through holes 11 are evenly distributed in the water inlet hole array area. In this embodiment, the through holes 11 are distributed in the water inlet hole array area in a rectangular array. In some embodiments, the through holes 11 can also be distributed in the water inlet array area in a plum blossom shape or other distribution shapes. In actual application, the water inlet hole array area is located in the upper half of the drainage pipe body 1, and the water outlet pipe groove area is located in the lower half of the drainage pipe body 1.

[0041] In some preferred exemplary embodiments, the central angle of the water inlet hole array area is 180° to 270°. Figure 2 As shown, in this embodiment, the central angle corresponding to the water inlet hole array area is 270°. In some embodiments, the central angle corresponding to the water inlet hole array area can also be 180°, 210° or other angles, and the technicians can set it according to their needs.

[0042] In some preferred exemplary embodiments, one end of the drain pipe body 1 is an inclined opening 13, and the end extending outward from the inclined opening 13 is located on the same side as the outlet pipe groove area of ​​the drain pipe body 1. By providing the inclined opening 13, dripping drainage can be facilitated, and when the entire drain pipe body 1 is installed, the orientation of the water inlet hole array area and the outlet pipe groove area can be avoided so that the outlet pipe groove area is located in the upper half of the drain pipe body 1 and the water inlet hole array area is located in the lower half of the drain pipe body 1, which affects the drainage effect.

[0043] In some preferred exemplary embodiments, the distance between the oblique opening 13 and the annular groove 12 is at least 20 cm.

[0044] In some preferred exemplary embodiments, the drainage pipe body 1 is made of PVC material to ensure the durability of the pipe in a long-term humid environment. In some embodiments, pipes made of other materials, such as aluminum alloy, may also be used, but the cost is more expensive.

[0045] In some preferred exemplary embodiments, the diameter of the drain pipe body 1 ranges from 5 cm to 10 cm. The length, diameter and other dimensions of the drain pipe in this embodiment can be adjusted by technicians as needed.

[0046] In some preferred exemplary embodiments, the water filter sandbag 2 is in a cylindrical shape that matches the drain pipe body 1. The cylindrical shape of the water filter sandbag 2 is convenient for installation, replacement and maintenance.

[0047] When using this embodiment, first clean and level the slope surface, then drill holes with an elevation angle of not less than 6° and a diameter of 7.5-12.5 cm into the slope body at a certain interval according to the properties of the rock and soil on the slope surface and the water content. The length needs to pass through the slope pit and the deep aquifer. After the holes are formed, insert the present application into the hole in the slope body, and expose the drainage pipe body 1 on one side of the inclined mouth 13 for more than 20 cm.

[0048] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
