Embodiment 1

[0020] Embodiment 1, two foam boxes with a length of 50 centimeters, a width of 40 centimeters and a height of 20 centimeters are overlapped, and a round hole with a diameter of 15 centimeters is opened at the middle bottom of the foam boxes above, and a bottom with a diameter of 15 centimeters and a length of 20 centimeters is used. The water pipe connects the two boxes, and then the upper box is equipped with prepared soil, and the inside of the 15 cm diameter downpipe is equipped with prepared cinders, and then plants are planted in the upper foam box, and the lower foam box is filled with water. After a period of observation, when the plants growing in the box need water, the root system of the plant will absorb it from the soil in the box, and the flow of water in the soil will naturally form the water in the water storage tank below to pass through the downpipe The key to upward conduction is the excellent conductivity of cinder. A downpipe with a diameter of 15 cm only ...

Embodiment 2

[0027] Embodiment 2, roof shallow soil layer water-retaining garden is made up of three parts, and upper strata part is soil tank 1, lower part is water storage tank 2, the notch 5 of coal cinder batching part connects up and down, is referred to as coal cinder batching tank (3), as attached figure 1 shown. Build any length shape on the roof garden, 60 centimeters wide, 20 centimeters deep rainwater storage tank 2, then lay dividing plate 7 on the water storage tank 2, dividing plate 7 can use plastic dividing plate 7 or other product dividing plate 7, promptly not afraid of water Anything that can bear the weight will do. Then stay a 30 * 10 * 20 centimeters rectangular coal cinder batching notch 5 in the middle of each 50 centimeters of dividing plate, coal cinder batching groove 3 four walls (as image 3 Shown) there are countless hole walls 6 of about 1 centimeter, and the effect is that rainwater conducts up and down from cinder batching tank 3 li.

[0028] Then in the ...

Embodiment 3

[0030] Embodiment 3: Utilize this principle and also can make water storage tank 2 become independent individual, independent individual can be pottery product, cement product or plastic product, and independent water storage individual advantage is to reduce roof seepage coefficient, finally with soil It is enough to connect the grooves 1 together, and the connection of the soil loading groove 1 is mainly to facilitate the connection of the soil, so that the roots of the plants can freely extend and absorb water. Overflow hole 9 overflows unnecessary water.

Abstract

The invention discloses a greening device for keeping water in the shallow soil layer of the roof, which is composed of a soil tank, a water storage tank, a coal cinder batching tank and a partition between the soil tank and the water storage tank as a whole or through connection. The soil in the soil tank The layer and the water in the water storage tank pass through the holes on the wall of the cinder tank and the cinder ingredients in it are connected up and down, left and right to transfer the water required by the plants. The cinder ingredients refer to 60% to 90% cinder material and 40% cinder. % to 10% soil mixture or pure cinder material; cinder ingredients conduct moisture range: cinder ingredients occupy 5% to 80% of the volume of the water storage tank, and can be planted and greened after passing the inspection or experiment. The invention solves the problem of long-term and heavy watering management for roof greening, so that roof plants no longer lack water due to shallow soil, and after special technical treatment, there is no need to worry about roof leakage and load bearing. The structure of the invention is simple, the materials and ingredients are easy to obtain, the investment is small, the operation is convenient, and it has certain economic and social benefits.

Description

technical field [0001] The invention relates to greening and water-retaining planting technology, which is widely used in greening roofs, balconies, roads, bridges, and Gobi deserts, and planting trees and vegetables, in particular to a water-retaining greening device for shallow soil layers on roofs. Background technique [0002] Due to the special environment of roof greening and the shallow soil layer on the roof, roof greening has always been a huge technical problem in front of roof greening technicians from all over the world. How to solve the problem of shallow roof soil and poor water retention performance, which seriously affects the growth of plants. Technicians from all over the world have studied many construction methods, but the solution to roof greening is not ideal, and a lot of water resources, manpower and material resources are wasted, and roof greening management costs It is also very high, and the shallow roof soil also makes the roof soil heat up quickl...
