Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Example 1

Referring to fig. 1-6, the subsidence type green land structure with partitioned drainage comprises a rubble layer 4, a permeable geotextile layer 5, a water storage pottery soil layer 6, a sand layer 7 and a planting soil layer 8 are sequentially arranged above the rubble layer 4 from inside to outside, the water storage pottery soil layer 6 is a novel inorganic water storage material, the average water storage rate of the pottery clay can reach 88%, and the maximum comprehensive water storage rate can reach 110%; 500kg of rainwater can be absorbed and stored by every cubic argil, and only a layer of special soil is laid on the green land of the city, so that the soil becomes a 'reservoir' with large and small sizes every rainy day; the clean rain water stored in these "reservoirs" will automatically provide sufficient water to the ground plants during the dry season each year. Is expected to become a third water source for water in Chinese cities after surface water and underground water. The impounded argil is prepared by a special process from widely available clay into honeycomb-like particles or plates with an internal structure. Each part of the prepared pottery clay is distributed with closed small pores with dense hemp and diameter of 0.5 mm to 5 mm. When rainwater flows into the small air holes, the small air holes can store water as much as the water storage tank. When the ground is dry, the small air holes filled with rain water are like human capillaries, and water required by plant growth is automatically sent to the roots of the plants. Even in the case of the big drought, the urban green land does not need to be watered manually frequently.

A plurality of mutually communicated guide pipes 9 are buried at the two inner sides of the planting soil layer 8, a funnel 10 is fixedly arranged at the top of each guide pipe 9, each funnel 10 comprises a funnel body 101, the top of each guide pipe 9 is fixedly connected with the corresponding funnel body 101, a cover body 106 is telescopically arranged at the top end face of each funnel body 101 through a telescopic mechanism, each telescopic mechanism comprises a jack 102, a limiting ring 104, a through hole 105, a cover body 106, a threaded column 107 and a clamping block 108, a plurality of jacks 102 are uniformly distributed on the top end face of the cover body 106 along the circumferential direction, a limiting ring 104 is fixedly arranged on the top end face of the cover body 106 through screws, the through holes 105 are uniformly distributed on the upper surface of the limiting ring 104 along the circumferential direction, the diameter of the through hole 105 is smaller than that of the insertion hole 102, the threaded columns 107 are inserted into the insertion holes 102, and the top ends of the threaded columns 107 extend outwards through the limiting ring 104 and then are fixedly connected to the lower surface of the cover 106. Through the lid that sets up telescopic machanism and connect, can be in daily use with lid 106 lock on funnel body 101, when torrential rain weather, upwards mention lid 106 again to let rivers get into in the drainage tube 9, the lid 106 that sets up like this can not take place to lose, the later maintenance of being convenient for.
