Description

Technical Field

[0001] The utility model belongs to the field of engineering building materials, in particular to a permeable pipe with a geotextile gland. Background Art

[0002] As a construction material, infiltration pipe has a wide range of applications. In addition to soil improvement, it can also be used in groundwater management, drainage systems and flood prevention measures. Infiltration pipes need to be covered with geotextiles during construction and installation. The purpose of geotextile covering is to prevent gravel, sand, etc. from entering the pipe and protect the pipe. The geotextile covering can be directly covering gravel and sand, or wrapped on the outer wall of the infiltration pipe in a winding manner. The current geotextile covering of the infiltration pipe does not have any effective fixing structure, which makes the geotextile slip during the construction process or use of the infiltration pipe. Therefore, it is necessary to provide a kind of infiltration pipe with a geotextile pressure cap that can fix the geotextile on the infiltration pipe. Utility Model Content

[0003] The utility model aims to provide an infiltration pipe with a geotextile pressure cover to solve the technical problem that the geotextile covering the infiltration pipe has no effective fixing structure, which causes the geotextile to slip during the construction or use of the infiltration pipe.

[0004] To achieve the above purpose, the specific technical solution of the utility model is as follows:

[0005] A permeation tube with a geotextile gland, comprising a permeation tube and a gland, wherein the permeation tube is evenly provided with permeation holes, the gland comprising an integrally formed top cover and a plug connection portion, the top cover having an abutting surface abutting against the outer surface of the permeation tube, the gland further comprising a support foot fixedly connected to the plug connection portion, the support foot having a clamping portion abutting against the inner surface of the permeation tube, the support foot having elastic deformation to be gathered toward the central axis of the plug connection portion or opened away from the central axis.

[0006] With this design, the geotextile is first covered on the infiltration tube, and then the geotextile at the infiltration hole is pierced into a cross, and the gland plug is pressed to connect the infiltration hole, so that the geotextile at the cut is clamped between the hole wall of the infiltration hole and the side wall of the plug joint, and the support leg clamping part is pressed until it hooks the inner wall of the infiltration tube, and the gland cannot be separated from the infiltration tube. The geotextile and the infiltration tube are effectively fixed.

[0007] Furthermore, the top cover and the plug connection part are cylindrical, and the diameter of the plug connection part is adapted to the aperture of the penetration hole. The cylindrical structure of the plug connection part is adapted to the penetration hole, and plugging the plug connection part into the penetration hole can achieve a certain degree of sealing effect, and the cylindrical plug connection part can be plugged into the penetration hole more smoothly.

[0008] Furthermore, the side of the plug connection part and the penetration hole is provided with a concave-convex part, and the concave-convex part is a friction-increasing structure. When the plug connection part and the side of the penetration hole clamp the geotextile, the concave-convex structure can increase the friction of the clamping, further preventing the geotextile from slipping. When the materials of the infiltration tube and the gland are both plastic, the concave-convex structure does not hinder the gland from being pressed into the penetration hole, and also makes the plug connection part and the penetration hole interference connected, thereby enhancing the strength of the plug connection.

[0009] Furthermore, the clamping part has a clamping surface and a guide surface, the clamping surface abuts against the inner surface of the permeation tube, the guide surface is inclined toward the inside of the permeation tube, and the angle between the guide surface and the central axis of the plugging part is 50°-80°. The guide surface has a predetermined angle relative to the hole wall of the permeation hole, and when the top cover is plugged into the permeation hole, the second table surface has a guiding function.

[0010] Furthermore, the gland is provided with a through hole, which penetrates the top cover and the plug connection part along the central axis direction of the plug connection part, and a filtering structure is provided in the through hole. The filtering structure enables the cover body to flow liquid normally and excludes debris such as sand and stones from the infiltration tube. Through such a design, the gland can fix the geotextile on the outer surface of the infiltration tube without affecting the water leakage function of the infiltration hole with which it is assembled, and the filtering structure can also prevent sand and dirt from entering the infiltration tube.

[0011] Furthermore, the filtration structure includes a filter screen and a barrier layer, the filter screen is installed at one end of the through hole close to the outer surface of the permeation tube, the barrier layer is arranged at one end of the through hole close to the inner surface of the permeation tube, and a water outlet is provided on the barrier layer, and the water outlet is staggered in the axial direction of the through hole.

[0012] Furthermore, it also includes a reinforcing hoop, which is sleeved on the outer surface of the permeation tube, and is provided with a positioning hole. The reinforcing hoop clamps the gland to the permeation hole, and the positioning hole is aligned with the permeation hole or the gland. The reinforcing hoop is sleeved on the permeation tube, and the positioning hole is used for alignment and positioning when the reinforcing hoop is installed, and can also ensure the normal function of the gland and the permeation hole.

[0013] Furthermore, the permeation hole is in a frustum shape, and the diameter of the permeation hole gradually decreases along the radial direction from the outer surface to the inner surface of the permeation tube. With such a design, the permeation holes on the permeation tube can be set to be in a frustum shape, or only the permeation holes that are installed in conjunction with the gland are designed to be in a frustum shape, and the frustum-shaped permeation holes can play a guiding role when the gland is assembled.

[0014] The beneficial effects of the utility model are as follows: first, the geotextile is covered on the infiltration tube, and then the geotextile located at the infiltration hole is poked into a cross-shaped cut, and the pressure cover is pressed to connect the infiltration hole so that the geotextile at the cut is clamped between the hole wall of the infiltration hole and the side wall of the plug connection part, and is pressed until the support foot clamping part hooks the inner wall of the infiltration tube, thereby ensuring the connection stability between the pressure cover and the infiltration tube, and effectively fixing the geotextile and the infiltration tube.

[0023] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0024] like Figures 1 to 7 As shown:

[0025] Example 1

[0026] Example 1 The infiltration tube with a geotextile gland includes a infiltration tube 4 and a gland. The infiltration tube 4 is evenly provided with infiltration holes 3. The gland includes an integrally formed top cover 1 and a plug connection portion 2. The top cover 1 has an abutting surface abutting against the outer surface of the infiltration tube 4. The gland also includes a support foot 5 fixedly connected to the plug connection portion 2. The support foot 5 has a clamping portion 6 abutting against the inner surface of the infiltration tube 4. The support foot 5 can be retracted toward the central axis of the plug connection portion 2 or opened away from the central axis in the radial direction of the plug connection portion 2.

[0027] The top cover 1 and the plug connection part 2 are cylindrical, and the diameter of the plug connection part 2 is matched with the aperture of the penetration hole 3 .

[0028] The side surface of the plug connection part 2 and the penetration hole 3 is provided with a concave-convex part, and the concave-convex part is a friction-increasing structure.

[0029] The clamping part 6 has a clamping surface 7 and a guide surface 8. The clamping surface 7 abuts against the inner surface of the permeation tube 4. The guide surface 8 is inclined toward the inside of the permeation tube 4. The included angle between the guide surface 8 and the central axis of the plugging part 2 is 50°-80°.

[0030] The implementation method of the above embodiment is as follows: laying the infiltration tube 4 according to the predetermined construction process, covering the geotextile on the infiltration tube 4, and exploring and determining the position of the infiltration hole 3; using a knife to pierce the geotextile located at the infiltration hole 3 into a cross-shaped cut, so that the cut portion of the geotextile can droop into the infiltration hole 3, the top cover 1 of the gland is against the infiltration tube 4, and the plug connection part 2 of the gland is pressed into the infiltration hole 3, so that the geotextile at the cut is clamped between the hole wall of the infiltration hole 3 and the side of the plug connection part 2. During the pressing process, the support leg 5 is subjected to the force of the infiltration hole 3 and is retracted until the clamping part 6 of the support leg 5 can expand outward to hook the inner wall of the infiltration tube 4, so that the gland maintains the connection position with the infiltration tube 4.

[0031] In a further embodiment: the gland is normally installed in cooperation with the upward permeation hole 3 on the permeation tube 4, but the gland can be set on the partially upward permeation hole 3, for example: in the same row of super upward permeation holes, the permeation holes with glands and the permeation holes without glands are arranged according to a predetermined arrangement rule, such as alternate arrangement or equal interval arrangement, and it is only necessary to ensure that there is enough force to fix the geotextile to the permeation tube 4. The side of the plug 2 in contact with the permeation hole 3 is evenly provided with a concave-convex structure 9, which is conducive to increasing the friction between the plug 2 and the side of the permeation hole 3, and further preventing the geotextile from falling off.

[0032] Example 2

[0033] The gland is provided with a through hole 10 , which penetrates the top cover 1 and the plug connection part 2 along the central axis direction of the plug connection part 2 , and a filtering structure is provided in the through hole 10 .

[0034] The filtration structure includes a filter screen 11 and a barrier layer 12. The filter screen 11 is installed at one end of the through hole 10 close to the outer surface of the permeation tube 4. The barrier layer 12 is arranged at one end of the through hole 10 close to the inner surface of the permeation tube 4. A water outlet 13 is provided on the barrier layer 12. The water outlet 13 is staggered in the axial direction of the through hole 10.

[0035] The implementation method of the above embodiment is: the gland may be provided with a filtering structure or not, because the gland is only installed on the upward-facing permeation hole 3 on the permeation tube 4. However, in order to minimize the hindrance to the water seepage function of the permeation tube 4, a through hole 10 may be opened on the gland and a filtering structure may be installed. The filter screen 11 serves as the first filter to exclude larger sand and gravel particles. When finer sand and gravel enter the filtering hole, the water outlet 13 of the barrier layer 12 is staggered to block the fine sand and gravel, thereby ensuring that as little fine sand and gravel as possible penetrates into the tube 4.

[0036] Example 3

[0037] The permeation tube further comprises a reinforcing hoop 14 which is sleeved on the outer surface of the permeation tube 4 and is provided with a positioning hole 15 which clamps the gland to the permeation hole 3 and the positioning hole 15 is aligned with the permeation hole 3 or the gland.

[0038] The implementation method of the above embodiment is: the reinforcing hoop 14 is sleeved on the permeation tube 4, and the positioning hole 15 is used for aligning and positioning the reinforcing hoop 14 during installation, which can also ensure the normal function of the pressure cover and the permeation hole 3. The reinforcing hoop 14 can enhance the compressive strength of the permeation tube.

[0039] The reinforcing hoop 14 is composed of two identical semicircular hoops that are detachably fixedly connected, or is cylindrical and tightly fitted on the outer circumference of the permeation tube.

[0040] Example 4

[0041] The permeation hole 3 is in a frustum shape, and the diameter of the permeation hole 3 decreases along the radial direction of the permeation tube 4 close to the central axis of the permeation tube 4, so that the permeation hole 3 is covered by a guide gland.
