Greening drainage plate structure

Abstract

The invention provides a greening drainage plate structure which comprises a sealing ring and spraying heads. Six fixing grooves are formed in the end face of the top of a greening planting plate, anda plurality of water storing grooves are further formed and mutually evenly distributed in the end face of the top of the greening planting plate. Sixteen supporting columns are located an empty layer formed between the greening planting plate and a waterproof bottom plate; a plurality of sets of positioning columns are mounted on the end face of the top of the greening planting plate and distributed on the peripheral positions of the water storing grooves; and filter nets and absorbent cotton are the same in number, and the filter nets are located in the middle positions where the absorbentcotton is located. The empty layer is formed in a device advantageously, a water flow is conveniently drained out of the device through the empty layer, and the drainage efficiency in the device is improved; and by being matched with using of the filter nets, the water flow leaked from the top of the device can be filtered, and thus the situation that large-particle impurities carried in the waterflow are accumulated in the drainage empty layer in the device, and consequently the normal drainage effect of the device is affected is avoided.

Description

technical field [0001] The invention belongs to the technical field of greening and drainage facilities, and more specifically relates to a greening and drainage board structure. Background technique [0002] With the increasing popularity of high-density residential areas and high-rise residences, the land available for planting plants in cities is becoming scarcer; at the same time, people's requirements for living environments are becoming higher and higher. [0003] In this context, roof gardens are increasingly used as auxiliary greening measures. Since most of these greening measures are carried out on the basis of impermeable buildings, it will inevitably cause the problem that rainwater cannot be infiltrated and eliminated in time. [0004] Based on the above, the inventor has searched, and for example, the patent No. CN104088408B discloses a siphon type green drainage tank structure, including a drainage tank body, and several reinforcing ribs are arranged on the d...

Problems solved by technology

[0008] In order to solve the above-mentioned technical problems, the present invention provides a green drainage board structure to solve the problem that the existing device has a poor internal water locking effect when it is in use, and the water flow is easily lost from the inside of the device, requiring frequent watering by personnel to ensure the normal water supply requirements of the green plants. , it is easy to increase the consumption of water resources, and the fixation effect on the green plant mats laid on the device at the initial stage is poor. Separation, the problem that affects the greening effect on the top of the house
