[0019] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings.

[0020] Example:

[0021] A water-saving intelligent irrigation system for mountain slope greening, such as Figure 1-2 As shown, it includes a water storage tank 1, a plurality of nozzles 2, a water pipe 3 connecting the plurality of nozzles 2 and the water storage tank 1, a water pump 4 installed on the water pipe 3, a humidity sensor for detecting soil moisture, and a controller for controlling the water output of the water pump 4 according to the soil moisture. The water storage tank 1 is arranged at the bottom of the slope, and the plurality of nozzles 2 are arranged above the greening of the slope. As in the prior art, the water pump 4 irrigates according to the soil moisture, and the water storage tank 1 collects and recycles the irrigation water for secondary use.

[0022] It also includes a diversion return water frame 5 buried in the soil layer below the slope greening, and a plurality of return water main channels 51 arranged in parallel to each other are formed on the diversion return water frame 5 for returning water to the water storage tank 1. The lower end of the return water main channel 51 is located above the water storage tank 1, and adjacent return water main channels 51 are connected by a plurality of return water branch channels 52 arranged side by side. The mountain slope greening is divided into a plurality of areas by the diversion return water frame 5.

[0023] During watering, the irrigation water in various areas of the slope greening can flow from the nearby return water diversion branch channel 52 to the return water main channel 51, and finally flow into the water storage tank 1. The irrigation water from various places will not gather at the bottom of the slope, and the soil erosion at the bottom of the slope will be small, thereby reducing the risk of soil loss on the mountain slope.

[0024] The main return water channel 51 includes two channel walls 1, and the channel wall 1 is higher than the soil layer of the mountain slope to ensure that the irrigation water flows smoothly into the water storage tank 1.

[0025] The backwater branch channel 52 includes an upper channel wall 521 and a lower channel wall 522 , and both the upper channel wall 521 and the lower channel wall 522 are higher than the soil layer of the mountain slope.

[0026] like Figure 3 As shown, the upper channel wall 521 has a water inlet portion 5211 made of a filter mesh body. The filter mesh body can be a three-dimensional geonet. Impurities such as dead branches and leaves can be filtered through the upper channel wall 521, and soil can also be appropriately intercepted.

[0027] The lower flow channel wall 522 is also connected to a water retaining edge 523 folded toward the top of the slope, which can prevent the irrigation water from surging out of the return water branch channel 52 due to surging in the return water branch channel 52.

[0028] like Figure 2 As shown, the water pipe 3 comprises a main pipe section 33 installed in the return water main channel 51 and a branch pipe section 34 installed in the return water branch channel 52 and connected to the main pipe section 33.

The water pipe 3 also comprises a water pump installation section 31, and an output section 32 connected to the water pump installation section 31, and the output section 32 is connected to the main pipe section 33.

[0029] This structure and installation method of the water pipe does not affect the arrangement of vegetation and is not easily affected by the growth of vegetation. If it is necessary to repair or replace the water pipe in the later stage, it is also convenient. It only needs to stand on the diversion return water frame 5 to handle it.

[0030] The branch pipe section 34 is arranged along the path of the return water diversion branch channel 52, and a plurality of the nozzles 2 are arranged on the branch pipe section 34. The nozzles 2 are arranged in this way, so it is convenient to repair or replace them in the later stage. Only the user needs to stand on the diversion return water frame 5 to handle the repair.
