However, the water flow rate of rigid permeable pipes after covering with soil is often tested by field monitoring. It is necessary to build observation wells or observation points on site to record water level changes and flow data, which makes the testing process cumbersome and inefficient, and is not conducive to large-scale testing. Utility Model Content

[0003] In order to improve the convenience of detecting soil-covered permeable pipes, the present application provides a device for testing the water flow rate of soil-covered permeable pipes.

[0013] Optionally, the detection box includes a main box body and a mounting plate, the socket is formed on the mounting plate, and the mounting plate is detachably connected to the side of the main box body.

[0014] By adopting the above technical solution, multiple mounting plates are set up so that the sockets on different mounting plates can adapt to water-permeable pipes of different calibers respectively. When detecting the water-permeable pipes, the mounting plates with corresponding calibers are assembled to the main box body, so that the equipment can adapt to water-permeable pipes of different calibers and improve the adaptability of the equipment.

[0015] Optionally, two clamping seats are abutted and moved on one side of the mounting plate, and the two clamping seats are respectively opposite to the two sides of the socket.

[0017] Optionally, the adjusting member includes a base seat and a driving rod, the base seat is fixed on the mounting plate, the driving rod is threadedly moved along the distribution direction of the two clamping seats and is passed through the base seat, and the end of the driving rod close to the socket is rotated on the clamping seat.

[0018] By adopting the above technical solution, the driving rod is moved by the thread so as to drive the clamping seat to move quickly and conveniently.

[0019] Optionally, the adjusting member includes a fixed seat, a sliding rod and a locking rod, the fixed seat is fixed on the mounting plate, the sliding rod is slidably inserted into the fixed seat along the distribution direction of the two clamping seats, and the sliding rod is connected to the clamping seat at one end close to the socket; the locking rod is threadedly moved on the fixed seat along a direction perpendicular to the sliding direction of the sliding rod, and the sliding rod has a positioning hole for inserting the locking rod.

[0020] By adopting the above technical solution, the locking rod is threadably moved to be inserted into the sliding rod to limit the movement of the sliding rod relative to the fixed seat, thereby positioning the clamping seat.

[0036] The following is combined with Figure 1-6 This application is described in further detail.

[0037] Embodiment 1:

[0038] The present application embodiment discloses a water permeability test device for a soil-covered water permeable pipe. The outer wall of the water permeable pipe has a water permeable gap (not shown in the figure) connecting the inside and outside of the water permeable pipe, and the outside of the water permeable pipe is covered with a geotextile. Figure 1 The water flow rate testing equipment for a permeable pipe covered with soil comprises a testing box 1 and a covering member 10.

[0039] Reference Figure 1 and Figure 2 The detection box 1 includes a main box body 101 and a mounting plate 102. The main box body 101 is in the shape of a square box with an opening facing upward. A clearance opening 11 connecting the inside and outside of the main box body 101 is provided on a side wall of one side of the main box body 101. The mounting plate 102 is in the shape of a square sheet, and the size of the mounting plate 102 is larger than the size of the clearance opening 11. The mounting plate 102 is provided with a socket 2 that passes through two opposite sides of itself. Through holes for bolts to pass through are provided at the four corners of the mounting plate 102. A thread groove for bolt thread connection is provided near the clearance opening 11 of the main box body 101, and the thread groove corresponds to the through hole one by one.

[0040] The mounting piece 102 is pressed against the outer wall of the main box body 101 having the clearance opening 11, and then the bolt rod is passed through the mounting piece 102 and threadedly connected to the main box body 101, and the bolt head is pressed against the side of the mounting piece 102 facing away from the main box body 101 to lock the mounting piece 102 on the main box body 101, and the mounting piece 102 covers the clearance opening 11.

[0041] The cover member 10 is in the shape of a cover body that matches the main box body 101 . The cover member 10 can be sleeved downwardly on the top of the main box body 101 to close the top opening of the main box body 101 .

[0042] When conducting the test, one end of the water-permeable pipe is horizontally inserted into the main box 101 from the socket 2 of the mounting plate 102, and the end of the water-permeable pipe is against the inner wall of the main box 101, and the other end of the water-permeable pipe is located outside the main box 101. Then, soil is added to the main box 101 so that the soil buries the water-permeable pipe, and then water is added to the main box 101 so that the water penetrates through the soil into the water-permeable pipe. The water that penetrates into the water-permeable pipe will be discharged from the end of the water-permeable pipe located outside the main box 101. The water discharge amount of the water-permeable pipe is tested to detect the water permeability of the water-permeable pipe.

[0043] Reference Figure 1 and Figure 2 In addition, there are multiple mounting pieces 102, each mounting piece 102 has the same size, and the diameter of the socket 2 opened on each mounting piece 102 is different. Before the test, the mounting piece 102 whose socket 2 size is adapted to the water-permeable pipe to be tested is installed on the main box 101. By replacing the mounting piece 102 on the main box 101, the device can adapt to water-permeable pipes of different diameters, thereby improving the adaptability of the test equipment.

[0044] In order to improve the sealing between the mounting piece 102 and the main box body 101, the outer wall of the main box body 101 is coated with epoxy resin adhesive along the circumference of the clearance opening 11. After the epoxy resin adhesive is cured, an elastic sealing layer 12 is formed. When the mounting piece 102 is installed on the main box body 101, it is pressed against the sealing layer 12 to prevent a gap from leaking between the outer periphery of the mounting piece 102 and the main box body 101.

[0045] Reference Figure 2 and Figure 3 Furthermore, a liquid level tube 3 is installed on the main box 101. The liquid level tube 3 includes a connecting head 31 and a tube body 32. The tube body 32 extends in a straight line direction and is made of a transparent material, preferably plastic. There are two connecting heads 31. The two connecting heads 31 are respectively connected and connected to the two ends of the tube body 32 that are far away from each other, and the two connecting heads 31 are respectively installed at the upper and lower ends of one side of the main box 101. Specifically, the connecting head 31 has a water inlet end and a water outlet end. The water inlet end of the connecting head 31 is inserted into the main box 101 and communicates with the inner cavity of the main box 101. The water outlet end of the connecting head 31 is located outside the main box 101 and connected to the end of the tube body 32.

[0046] The tube body 32 extends vertically outside the main box body 101, and the water in the main box body 101 enters the tube body 32 from the connecting head 31, so that the water level in the tube body 32 is synchronized with that in the main box body 101. By observing the changes in the water level in the tube body 32, the changes in the water level in the main box body 101 can be observed, so as to more intuitively demonstrate the drainage effect of the permeable pipe and facilitate timely water replenishment when the water volume decreases.

[0047] Reference Figure 2 and Figure 3Furthermore, the water inlet end of the connecting head 31 is detachably connected with a water filter head 4, which is in the shape of a cover and is threadedly sleeved on the water inlet end of the connecting head 31. A plurality of water filter holes 5 are arranged in an array on the part of the water filter head 4 that is opposite to the pipe opening of the water inlet end of the connecting head 31. The water filter holes 5 are used to supply water and limit the passage of soil in the main box 101, so that the soil is not easy to enter the pipe body 32 with the water flow, so as to improve the cleanliness of the pipe body 32. When it is necessary to clean the water filter holes 5, the water filter head 4 can be screwed off from the connecting head 31.

[0048] Reference Figure 2 Furthermore, in order to facilitate water replenishment, a water diversion head 6 is installed on the main box 101. The water diversion head 6 is in the shape of a tube with two ends connected. The water diversion head 6 is arranged on the box wall at one end of the main box 101, and the outer peripheral wall of the water diversion head 6 located outside the main box 101 has an external thread. The pipe of the external water source (not shown in the figure) is threadedly connected and communicated with the water diversion head 6, so that the external water source can convey water to the main box 101 through the water diversion head 6. The water diversion head 6 is close to the top of the main box 101, and the soil in the main box 101 is located below the water diversion head 6 to simulate the situation of rainwater penetrating the soil in the actual field.

[0049] The implementation principle of the soil-covered water flow rate test equipment for a permeable pipe in an embodiment of the present application is as follows: a mounting plate 102 adapted to the permeable pipe to be tested is mounted on a main box body 101, and then the permeable pipe to be tested is horizontally passed through the mounting plate 102 into the main box body 101, and soil is filled into the main box body 101 to bury the permeable pipe to be tested, and then water is transported into the main box body 101, and the water flows through the soil into the permeable pipe and is discharged from one end of the permeable pipe located outside the main box body 101, and the water permeability of the permeable pipe is tested by measuring the water discharge volume of the permeable pipe.

[0050] Embodiment 2:

[0051] When the water-permeable pipe passes through the socket 2 and the mounting plate 102, there is a gap between the inner wall of the mounting plate 102 at the socket 2 and the water-permeable pipe, so that the water-permeable pipe can move relative to the mounting plate 102. However, when soil is placed in the main box 101, the soil is likely to push the water-permeable pipe to move relative to the mounting plate 102, causing the length of the water-permeable pipe in the main box 101 to change, affecting the test effect. In order to improve this problem, the embodiment of the present application discloses a water-permeable pipe soil-covered water flow test device.

[0052] The difference between this embodiment and the first embodiment is that, referring to Figure 4 The water permeable pipe soil covering water flow test device also includes a clamping seat 7 and an adjusting member 8. The clamping seat 7 has two, and the two clamping seats 7 are respectively located on the upper and lower sides of the mounting plate 102, and the two clamping seats 7 are respectively opposite to the upper and lower sides of the socket 2.

[0053] Reference Figure 4and Figure 5 The clamping seat 7 corresponds to the adjusting member 8 one by one. The adjusting member 8 is installed between the mounting plate 102 and the corresponding clamping seat 7 to drive the clamping seat 7 to move up and down at the mounting plate 102 and position the clamping seat 7.

[0054] After the water-permeable pipe passes through the mounting plate 102 and reaches the designated mounting position, the adjusting member 8 drives the clamping seat 7 to move so that the two clamping seats 7 are respectively pressed against the upper and lower sides of the water-permeable pipe, so that the water-permeable pipe can be positioned relative to the mounting plate 102, thereby improving the stability of the water-permeable pipe and preventing the water-permeable pipe from being displaced relative to the main box body 101 when the main box body 101 is filled with soil.

[0055] Reference Figure 5 The clamping seat 7 includes a hard layer 71 and a rubber layer 72. The hard layer 71 and the rubber layer 72 are both arc-shaped and coaxially fixed. The rubber layer 72 is located on the side of the hard layer 71 facing the socket 2. The hard layer 71 and the rubber layer 72 are both against the side of the mounting plate 102. The hard layer 71 is a hard material made of metal, and the rubber layer 72 is a rubber material with elasticity, and the inner diameter of the rubber layer 72 is close to and smaller than the outer diameter of the water-permeable pipe.

[0056] When the clamping seat 7 is pressed against the water-permeable pipe, the rubber layer 72 is pressed against and fits the water-permeable pipe, and the rubber layers 72 of the two clamping seats 7 together form a ring that hugs the water-permeable pipe, and the rubber layer 72 is squeezed and deformed by the water-permeable pipe and pressed against the mounting plate 102, so that the rubber layer 72 positions the water-permeable pipe and at the same time seals the gap between the mounting plate 102 and the outer wall of the water-permeable pipe, so that the water in the main box 101 is not easy to overflow from the outer wall of the water-permeable pipe and the mounting plate 102, so as to improve the sealing between the water-permeable pipe and the mounting plate 102.

[0057] Reference Figure 4 and Figure 5 The adjusting member 8 in this embodiment includes a base 81 and a driving rod 82. The base 81 is fixed on the side of the mounting plate 102. The driving rod 82 moves along the vertical thread and penetrates the base 81. The end of the driving rod 82 close to the socket 2 rotates on the hard layer 71 of the corresponding clamping seat 7. The clamping seat 7 is driven to move up and down by rotating the driving rod 82. The clamping seat 7 is positioned by stopping the driving rod 82 from rotating. The clamping seat 7 is restricted from rotating together with the driving rod 82 by contacting the side of the mounting plate 102.

[0058] The implementation principle of the water flow rate testing device for a soil-covered water permeable pipe in the embodiment of the present application is as follows: after the water permeable pipe passes through the installation plate 102 and reaches the installation position, the threaded moving drive rod 82 drives the clamping seat 7 to move, so that the two clamping seats 7 clamp the water permeable pipe together to position the water permeable pipe.

[0059] Embodiment three:

[0060] The difference between the present embodiment and the second embodiment lies in the difference of the adjusting member 8. Figure 6 The adjusting member 8 in the embodiment of the present application includes a fixing seat 83 , a sliding rod 84 and a locking rod 85 .

[0061] Reference Figure 6 and Figure 7 The fixing seat 83 is fixed to the side of the mounting plate 102, the sliding rod 84 slides up and down and is arranged on the fixing seat 83, and the end of the sliding rod 84 close to the socket 2 is fixed to the hard layer 71 of the corresponding clamping seat 7. The sliding rod 84 has an abutment portion 13, which protrudes from the side of the sliding rod 84 and is opposite to the side of the fixing seat 83 away from the socket 2.

[0062] When the sliding rod 84 moves to the abutting portion 13 and abuts against the fixed seat 83, the abutting portion 13 restricts the sliding rod 84 from continuing to move toward the direction close to the socket 2. When the sliding rods 84 in the corresponding adjustment members 8 of the two clamping seats 7 abut against the fixed seat 83, the rubber layers 72 of the two clamping seats 7 together form a ring that tightly embraces the water-permeable pipe.

[0063] The locking rod 85 is threadedly moved on the fixing seat 83 in the horizontal direction and is opposite to the sliding rod 84. The sliding rod 84 is provided with a positioning hole 9 for the locking rod 85 to be inserted. When the abutting portion 13 abuts against the fixing seat 83, the positioning hole 9 is opposite to the locking rod 85. At this time, the locking rod 85 can be threadedly moved to be inserted into the positioning hole 9, so that the sliding rod 84 and the fixing seat 83 are positioned relative to each other, thereby positioning the clamping seat 7 relative to the mounting plate 102.

[0064] 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.
