Drain board with functions of water draining, retaining, storing and collecting

Abstract

Provided is a drain board with functions of water draining, retaining, storing and collecting. The drain board is arranged at a portion requiring smooth water draining, the functions of water draining, retaining, storing and collecting are achieved, and landscaping trees are prevented from being damaged or withered. The drain board comprises a combining structure body for draining water and filtering cloth. The combining structure body is formed by a lower drain board and an upper drain board. A plurality of first protrusion blocks arranged into a grid shape are arranged on the surface of the lower drain board in upward protruding mode, and vertical portions with the same height as the first protrusion blocks are arranged at two ends of the lower drain board. The upper drain board is arranged on the upper portion of the lower drain board, a plurality of second protrusion blocks arranged into a grid shape are arranged on the surface of the upper drain board in downward protruding mode, and the insides of the second protrusion blocks form depressed water storage bags with open upper portions. Drain holes penetrate through the second protrusion blocks to enable the second protrusion blocks to be communicated with one another. The height of the second protrusion blocks is larger than that of the first protrusion blocks. The upper drain board and the lower drain board are arranged oppositely so as to enable the first protrusion blocks and the second protrusion blocks to be opposite in staggered mode. The filtering cloth is arranged in attaching mode so as to surround the combining structure body for draining water, can be fixed with the upper drain board and the lower drain board integrally, and has a vertical permeation coefficient larger than 0.001 cm / sec.

Description

technical field [0001] The invention relates to a drainage board with the functions of drainage, water retention, water storage and water collection, in particular to a drainage board that can be installed in places where drainage needs to be smooth, such as golf courses, tennis courts, sports fields, landfills, parks, amusement parks, etc. Site landscaping, tunnels, civil retaining walls, etc., so that the functions of drainage, water retaining, water storage and water collection can all be realized, so as to avoid necrosis and death of landscaping trees. Background technique [0002] Typically, water can flow underground for hundreds of millions of years without man-made devices such as conduits or filters. The main source of groundwater is rainwater. The rainwater that falls on the ground seeps into the ground through the soil and rock gaps, and the mutual supply and demand functions can maintain a perfect balance. [0003] The natural cycle of water has been disrupted b...

AI Technical Summary

Problems solved by technology

[0008] However, the above-mentioned conventional drainage board 11 has the problem that all the water flowing in through the non-woven fabric 13 is discharged, that is, because the conventional drainage board 11 has no water storage function, the moisture in the upper part of the soil is insufficient, and there is a problem that the landscaping trees die.

Moreover, all the water will be discharged after it flows in, and the discharged water will flow out from both ends of the drain board 11, so the discharged water cannot be collected in a specific water storage tank.

[0009] In addition, in order to have the function of water storage, such as Image 6 As shown, the drainage board 11 is placed upside down, so that the direction of the protrusion 12 is reversed up and down, and the non-woven fabric 13 is arranged on the upper part, and the through hole 14 is formed on the bottom surface of the drainage board 11. The inner side of the block 12 can have a water storage function, but because the water cannot be discharged horizontally, there will be water accumulation on the artificial foundation, which will cause the root rot of the landscaping trees

[0010] As mentioned above, there is no drainage board that integrates the functions of drainage, water retention, water storage and water collection. Therefore, there are many problems such as the need to individually select and install the drainage board with the required functions.
