[0001] The invention relates to the technical field of drainage, in particular to a high-strength underground drainage system. Background Art

[0002] In railway tunnel construction, the excavated slag needs to be piled in ravines, plains, hillsides and other areas; since the newly piled soil and rocks are relatively loose, their stability is poor; on the one hand, the soil and rocks contain some moisture; on the other hand, in rainy or humid conditions, water will seep down to the piled contact surface, which can easily cause the piled slag to slide; similarly, this type of problem exists not only in railway tunnel construction, but also in highway construction, water conservancy excavation and other fields. Summary of the invention

[0003] In view of the above problems, the purpose of the present invention is to provide a high-strength underground drainage system. The technical solution adopted by the present invention is as follows:

[0004] A high-strength underground drainage system comprises a plurality of pipe bodies and expansion joints connected between adjacent pipe bodies and used for seepage convergence and expansion connection of adjacent pipe bodies;

[0005] The tube body includes an arched tube body and a rectangular tube body arranged up and down and formed integrally, a plurality of water seepage holes are provided on the arched tube body, and a reinforcing rib connected to the inner wall of the arched tube body at one end and to the inner wall of the rectangular tube body at the other end;

[0006] A connecting ear is arranged between the pipe body and the expansion joint to press the expansion joint onto the pipe body.

[0007] Furthermore, rectangular conduits are respectively provided on both sides of the rectangular tube body, and a U-shaped groove is provided on the top of any of the rectangular conduits.

[0008] Preferably, the high-strength underground drainage system further includes a supplementary ring arranged between the pipe body and the expansion joint, wrapped around the outer edge of the arched pipe body, and with its ends embedded in the U-shaped groove one by one; the arc diameter of the supplementary ring is equal to the width of the rectangular pipe body.

[0009] Preferably, at least one circle of backstop ring is provided on the outer edge of the supplementary ring, and the inner wall of the telescopic joint is provided with an inner backstop ring which is complementary and limitedly connected with the backstop ring.

[0010] Furthermore, the connecting ear includes a first connecting bolt ear, a first arc-shaped connecting part, a U-shaped connecting part, a second arc-shaped connecting part and a second connecting bolt ear which are integrally formed and squeeze the expansion joint onto the tube body; the first connecting bolt ear and the second connecting bolt ear are both provided with connecting holes which are connected to each other.

[0011] Preferably, the outer edge of the arched tube is wrapped with geotextile.

[0012] A high-strength underground drainage pipe body connection structure, the drainage pipe body comprises an arched pipe body and a rectangular pipe body arranged up and down and formed in one piece; the drainage pipe bodies are provided with a plurality of them, and expansion joints are provided between adjacent drainage pipe bodies; rectangular confluence channels are provided on both sides of the rectangular pipe body, and a U-shaped groove is provided on the top of any of the rectangular confluence channels;

[0013] The high-strength underground drainage pipe body connection structure includes a supplementary ring arranged between the pipe body and the expansion joint, wrapped around the outer edge of the arched pipe body, and the ends of which are embedded in the U-shaped groove one by one, the outer edge of the supplementary ring is arranged in a ring shape, and at least one circle of stop ring, an inner stop ring is arranged on the inner wall of the expansion joint and is complementary and limitedly connected to the stop ring, and a connecting ear is arranged between the pipe body and the expansion joint and is used to squeeze the expansion joint onto the pipe body.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) The present invention ingeniously uses an expansion joint as a component for expansion connection and water seepage backflow. In order to ensure its pressure bearing capacity, reinforcing ribs are provided. Although the pipe body provided with reinforcing ribs has sufficient pressure bearing capacity, it also collects, divides and blocks the water seepage. This causes the problem of inconsistent water levels in the area of ​​the reinforced ribs, and also causes the problem of poor drainage capacity. The present invention ingeniously provides an expansion joint to collect and maintain the water seepage of the previous section of the pipe body on the same water surface, thus completely solving the problem of poor drainage capacity.

[0017] (2) The present invention cleverly arranges an arched tube body to increase the contact area and improve the water absorption capacity;

[0018] (3) The present invention ingeniously arranges a supplementary ring to fill the part connected with the expansion joint, which can not only meet the contact area of ​​the arched tube body, but also take into account the stable connection; under the extrusion connection effect of the connecting ear, the connection and sealing between the tube body and the expansion joint are more reliable;

[0019] (4) The present invention provides a stop ring on the supplementary ring, and provides a stop inner ring on the inner wall of the expansion joint that is complementary and limitedly connected to the stop ring, thereby effectively preventing the expansion joint from slipping off the pipe body;

[0020] In summary, the present invention has the advantages of simple structure, reliable connection, strong pressure bearing capacity, etc., and has high practical value and promotion value in the field of drainage technology. BRIEF DESCRIPTION OF THE DRAWINGS
