DETAILED DESCRIPTION

[0022] The utility model is further described below:

[0023] See also Figure 1-7 ,

[0024] The utility model discloses a novel concrete sand pipe for vertical drainage of slope surface, comprising a drainage pipe unit 1, a drainage well 2 and a connecting nut 3, wherein the right end of the drainage pipe unit 1 is a tapered end 4, and the left end of the drainage pipe unit 1 is a concave end 5, the tapered ends 4 and the concave ends 5 of adjacent drainage pipe units 1 are connected via the connecting nut 3, and the right end of the rightmost drainage pipe unit 1 is connected to the bottom end of the drainage well 2, and the drainage pipe is formed by connecting the tapered ends 4 and the concave ends 5 of adjacent drainage pipe units 1 via the connecting nut 3. The drainage pipe is easy to carry and transport, and is relatively easy to install, realizing a simple drainage system design, reducing drainage hidden dangers, and avoiding the problems of easy wear of woven bags, small drainage volume, and difficulty in secondary construction during the installation and use of traditional woven bag slope vertical drainage systems, thereby improving the drainage efficiency of the slope vertical drainage system and avoiding the occurrence of tailings blocking the drainage pipe accident caused by damage to the woven bags.

[0025] Furthermore, the conical end 4 includes a first conical ring 41 and a second conical ring 42, the left end of the first conical ring 41 is connected to the outer wall of the drain pipe unit 1, the right end of the first conical ring 41 is inclined upward, the left end of the second conical ring 42 is connected to the right end of the first conical ring 41, and the right end of the second conical ring 42 is inclined downward. The outer diameter of the right end of the second conical ring 42 is equal to the outer diameter of the drain pipe unit 1, and the left end surface of the concave end 5 is formed for the conical ring 5. The conical groove 51 is inserted into the right end of the conical end 4, and the outer wall of the cross-section of the conical groove 51 has the same slope as the outer wall of the cross-section of the second conical ring 42; the outer diameter of the concave end 5 is greater than the maximum outer diameter of the conical end 4, and the left end of the outer wall of the concave end 5 is provided with an external thread, and the connecting nut 3 includes a limiting ring 31 and a connecting ring 32, the inner diameter of the limiting ring 31 is equal to the outer diameter of the drain pipe unit 1, and the outer diameter of the limiting ring 31 is equal to the outer diameter of the concave end 5; the inner wall of the connecting ring 32 is on the left side. The end is connected to the outer wall of the limiting ring 31, and the right end of the inner wall of the connecting ring 32 is provided with an internal thread matching the external thread of the concave end 5. When connecting, first insert the tapered end 4 into the tapered groove 51 of the concave end 5 through the second tapered ring 42 with the same slope, and then tighten the connecting nut 3 mounted on the outer wall of the drain pipe unit 1 through the internal thread of its inner wall and the external thread of the concave end 5 until the right end of the limiting ring 31 is tightened against the left end of the first tapered ring 41 to complete the connection between the tapered end 4 and the concave end 5; in addition, it should be noted that since the maximum outer diameters of the tapered end 4 and the concave end 5 are both larger than the minimum outer diameter of the connecting nut 3, the connecting nut 3 cannot be later mounted on the outside of the drain pipe unit 1. Therefore, the drain pipe unit 1 can be divided into two sections in the middle in advance during production, and the two sections can be welded after the connecting nut 3 is mounted on the outside of the drain pipe unit 1. The advantage of this is that the connecting nut 3 does not need to be reinstalled during transportation and installation, and the connecting nut 3 is not easy to lose.

The inner ring of the left end face of the concave end 5 is provided with a chamfered right angle 52. Since the O-ring 6 is made of rubber material, in order to ensure sealing, its outer diameter must be larger than the outer diameter of the sealing ring groove 43. By providing the chamfered right angle 52 on the inner ring of the left end face of the concave end 5, the tapered end 4 can pass through the O-ring more easily when inserted into the concave end 5.

The depths of the connecting grooves 71 are equal; a locking nut 8 is provided on the outside of the drainage well 2, and a nut connecting groove 81 is provided at the bottom end of the inner wall of the locking nut 8.
