DETAILED DESCRIPTION

[0021] The utility model is described in detail below in conjunction with the accompanying drawings.

[0022] like Figure 1-5 As shown, a retaining wall structure for road engineering includes a base 11 and a supporting wall panel 12. A mounting groove 27 is provided on the retaining side of the supporting wall panel 12. A filtering device is provided in the mounting groove 27. A drainage hose 14 is connected to the lower end of the rear of the mounting groove 27. A through groove 17 is provided on the base 11. The drainage hose 14 passes through the through groove 17 and extends to the bottom of the base 11.

[0023] The filtering device comprises a water seepage plate 13 , a water permeable filler 25 and a reverse filter layer 26 which are arranged in sequence from front to back. A plurality of water seepage holes 28 are provided on the water seepage plate 13 .

[0024] A drainage frame 16 is disposed at the bottom of the base 11 . A plurality of drainage holes 29 are opened at the bottom of the drainage frame 16 . The drainage port 15 of the drainage hose 14 is located in the drainage frame 16 .

[0025] There are multiple groups of mounting grooves 27 , filtering devices and drainage hoses 14 to ensure drainage efficiency and reduce the pressure on the supporting wallboard 12 caused by accumulated water.

[0026] The supporting wall panel 12 is hinged on the base 11, and an angle adjustment mechanism is provided between the supporting wall panel 12 and the base 11. There are two groups of angle adjustment mechanisms.

[0027] The angle adjustment mechanism includes a first support rod 20, a second support rod 21 and a bidirectional screw 22; a first fixing seat 18 is provided on the upper surface of the base 11, and one end of the first support rod 20 is rotatably connected to the first fixing seat 18; a second fixing seat 19 is provided at the rear side of the supporting wall panel 12, and one end of the second support rod 21 is rotatably connected to the second fixing seat 19; internal threads are provided in the first support rod 20 and the second support rod 21, and both ends of the bidirectional screw 22 are respectively installed in the first support rod 20 and the second support rod 21 through threads. A hexagonal rotary block 23 is fixed in the middle of the bidirectional screw 22.

[0028] The construction personnel can adjust the angle of the supporting wall panel 12 at will according to the angle of the mountain. When adjusting, the bidirectional screw rod 22 is rotated by the hexagonal rotating block 23. Since the threads at both ends of the bidirectional screw rod 22 are in opposite directions, the first supporting rod 20 and the second supporting rod 21 are synchronously moved in relative or opposite directions, so that the overall length of the first supporting rod 20, the bidirectional screw rod 22 and the second supporting rod 21 can be adjusted, thereby adjusting the angle of the supporting wall panel 12.

[0029] The drainage frame 16 is connected to the roadside drainage ditch. When it rains, when there is too much water in the mountain, it flows to the supporting wallboard 12, and the rainwater mixed with mud and sand is filtered through the water seepage board 13, the permeable filler 25 and the filter layer 26 in turn, and then enters the drainage hose 14, flows from the drainage port of the drainage hose 14 to the drainage frame 16, and finally flows into the roadside drainage ditch through the drainage hole 29, so as to prevent the rainwater from spreading to the road surface and affecting the road traffic.

[0030] The rainwater enters the drainage hose 14 after being filtered, so as to avoid the drainage hose 14 and the drainage frame 16 from being blocked, thereby ensuring the normal drainage work.

[0031] A drainage frame 16 is provided at the drainage port 15 of the drainage hose 14 to prevent small animals from crawling into the drainage hose 14 and causing the drainage hose 14 to be blocked, thereby reducing safety hazards.
