and, locate slope protection module 500 on second clay layer 800, slope protection module 500 is equipped with a plurality of planting check 512, all is equipped with vegetable layer 600 in every planting check 512.

In this embodiment, the river bank 100 is a general term, and may be a bank disposed at a river side, a lake side, a river side, a reservoir bank in a cold region, a water diversion project bank, or the like, but is not limited to a bank disposed at a river side.

In addition, the slope of the river levee 100 is set as required, which is not specifically limited in this embodiment, and the frost heaving resistant slope protection structure provided in this embodiment is suitable for protection of river levees 100 of various slopes and lengths.

The beneficial effect of the frost heaving resistant slope protection structure that this embodiment provided includes, for example:

on the river levee 100 was located to frost heaving resistant side slope protection structure, slope protection structure was including the first clay layer 200, metalling 300, second clay layer 800 and the bank protection module 500 of range upon range of arranging in proper order, first clay layer 200 and domatic contact are equipped with vegetable layer 600 on the bank protection module 500, all are equipped with first sensor 210 on first clay layer 200 and the second clay layer 800, first sensor 210 is used for detecting whether first clay layer 200 and second clay layer 800 correspond position department and produce the crack. Meanwhile, the water pipe 400 is arranged in the crushed stone layer 300, the water pipe 400 is provided with a plurality of water outlets, the plurality of water outlets and the plurality of first sensors 210 are arranged in a one-to-one correspondence manner, that is, one water outlet is arranged at the position of one first sensor 210. Each water outlet is provided with a valve, and the valve can open or close the corresponding water outlet. The water pipe 400 is connected to a water pump for pumping river water, lake water or river water, and taking water on the spot according to the position of the river bank 100, so that the water resource utilization rate is high, and the cost is reduced. The water pump delivers water into the water delivery pipe 400. The first clay layer 200 and the second clay layer 800 can both block rainwater, so that rainwater is prevented from permeating into the river bank 100 from the slope protection module 500, and water in the river bank 100 is prevented from flowing back to the slope protection module 500. The interior and the surface of the river levee 100 are not easy to accumulate water, frost heaving is not easy to occur, and the structural stability is high.

Meanwhile, when the first clay layer 200 and the second clay layer 800 crack, after the crack is detected by the first sensor 210 at the corresponding position on the first clay layer 200 and the second clay layer 800, crack position information is transmitted to an intelligent terminal (such as a mobile phone, a computer or a flat plate), a maintainer controls the valve at the corresponding position to work according to the crack position information, so that the valve is opened, at the moment, the water pump discharges water from a water outlet corresponding to the crack position, the clay layer can expand after absorbing water, the crack is repaired, namely, the clay layer realizes self-repairing, rainwater is prevented from permeating from the crack position, the anti-seepage capability is improved, a large amount of accumulated water is not easy to appear inside the river bank 100, and the anti-freezing and anti-swelling effect is good.

It should be understood that after the first sensor 210 detects a crack, a small amount of self-repairing can be performed for many times, that is, by controlling the amount of water delivered to the clay layer during each repairing, gradual self-repairing is achieved, the repairing effect is good, the expansion volume is convenient to control, and the controllability is greatly improved.

Referring to fig. 2, in this embodiment, optionally, the number of the water pipes 400 may be one or more, in this embodiment, the number of the water pipes 400 is multiple, and the multiple water pipes 400 are uniformly arranged at intervals in the length direction of the river bank 100. Here, the longitudinal direction of the river bank 100 is the extending direction of the river. Thus, the plurality of water pipes 400 can basically cover the river levee 100, and water sources can be effectively conveyed to the position of the crack in time. The corresponding understanding shows that each water pipe 400 can be provided with one water pump, and the water pumps are independently controlled and are convenient and reliable to operate.

Optionally, each water pipe 400 includes a main pipe 410 and a plurality of branch pipes 420, each of the plurality of branch pipes 420 is communicated with one end of the main pipe 410, and the other end of the main pipe 410 is communicated with an outlet of the water pump. The plurality of branch pipes 420 are arranged in a staggered manner to form a net structure in the crushed stone layer 300, so that the coverage area is wide.

Referring to fig. 3, further, each branch pipe 420 is provided with a plurality of water outlets, the plurality of water outlets are distributed on the pipe wall of the branch pipe 420, and meanwhile, a port of the branch pipe 420 may also be provided with one water outlet. Every delivery port department is connected with a piece 430 that draws water, and every piece 430 that draws water is equipped with water delivery passageway and a plurality of outlet, and the delivery port intercommunication that corresponds on water delivery passageway's one end and the branch pipe 420, a plurality of outlets all communicate with water delivery passageway's the other end, and a plurality of outlets are the annular and arrange, and a plurality of outlets are around the first sensor 210 that corresponds and evenly arrange at interval in first sensor 210's circumference.

It should be understood that the water in the water pipe 400 is used for the transportation to the first clay layer 200 and the second clay layer 800, and thus, the plurality of branch pipes 420 connected to the main pipe 410 are divided into two layers, each layer of the branch pipes 420 is a net structure, and each layer of the branch pipes 420 has the water guide 430. Thus, the two layers of branch pipes 420 correspond to the positions of the first clay layer 200 and the second clay layer 800, respectively.

Through setting up a plurality of outlet into the annular mode of arranging around first sensor 210, so, after the crack is produced, the valve that corresponds crack department is opened, and water is discharged from a plurality of outlets simultaneously, can follow the cracked all around in flowing into the clay layer to make the crack reduce to the centre all around, finally realize cracked healing, the clay layer inflation is even, and crack repair effect is good.

It will be appreciated that the valve may be provided as a solenoid valve. The valve, the first sensor 210 and the water pump are in communication connection with the control system, the control system can be a computer, after the first sensor 210 detects crack information, the information is transmitted to the control system, the control system processes the information and then controls the water pump and the corresponding electromagnetic valve to be opened, and therefore the water pump conveys water to the corresponding crack, and self-repairing of the clay layer is achieved.
