The surface runoff passing through the catchment channel is pretreated by the sewage interception hanging basket device, the flow discarding filter device and the automatic filter device in advance before entering the box body 5, so that the surface runoff passing through the catchment channel is primarily purified. The sewage intercepting hanging basket device can intercept larger garbage and leaves; the flow discarding and filtering device is mainly used for automatically discharging and pre-filtering the heavily polluted rainwater in the early stage of rainfall; the automatic filtering device can automatically separate garbage and water in rainwater by utilizing the characteristic of rainwater gravity flow, so that cleaner rainwater is obtained.
By processing the pit 5, the cultivated land area can be effectively increased, and the newly increased cultivated land rate reaches 90%.
Example 2
As shown in fig. 4, the box catchment planting system of this embodiment is substantially the same as that of embodiment 1, the plurality of boxes are in the pit 21 for soil mining and brick burning, the plurality of cover plates 2 are located at the top of the plurality of boxes 5, and the boxes 5 which are close to the ditch 16 at the leftmost side and the rightmost side in the plurality of boxes 5 are all provided with water inlets, the water inlets are communicated with the ditch 16 outside the pit 21 for soil mining and brick burning through the water inlet pipes 11, the water inlets are provided with automatically controlled valves 17, the lower ends of the water inlets are provided with second level sensors 19, and the communicating parts of the water inlet pipes 11 and the ditch 16 are provided with the sewage blocking net 12.
The method for reclaiming the deep pit of the soil-mining baked brick by using the box catchment and earthing planting system is basically the same as the method for reclaiming the mine pit in the embodiment 1, and the difference is that: the reclamation object is a pit for the soil-mining and brick-burning, a catchment channel is additionally built on the surface of the ground around the pit for the soil-mining and brick-burning, the existing drainage and irrigation system is transformed and utilized, and then reinforced concrete anti-seepage treatment is carried out on the catchment channel additionally built and the existing drainage and irrigation system, so that the surface runoff around the pit 21 for the soil-mining and brick-burning can be naturally collected into the pit 21 for the soil-mining and brick-burning. Wherein the soil source of the soil covering planting layer 15 is from excavation soil generated in the process of building a catchment channel, modifying the existing drainage and irrigation system and building the box body 5. The bottom of the box body 5 is buried 5cm below the surface soil of the pit 21 for soil mining and brick firing.
By carrying out the treatment on the pit 21 for soil mining and brick burning, the cultivated land area can be effectively increased, and the newly increased cultivated land rate reaches 93 percent.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the scope of the present invention, which is intended to cover any modifications, equivalents, improvements, etc. within the spirit and scope of the present invention.
