Lawn bed structure of athletic sports lawn

Abstract

The invention discloses a lawn bed structure of an athletic sports lawn, belonging to the technical field of construction of lawn places. The lawn bed structure comprises bedding surfaces which are arranged from top to bottom and include lawn plants, a rooting zone layer, a non-woven fabric, water storage and drainage plate, a drain pipe and an original soil layer, wherein the water storage and drainage plate and the non-woven fabric are bonded into a whole, a complete entire sports ground is formed after laying, and soil in the rooting zone layer is directly laid on the non-woven fabric, so that the phenomenon of the surface unevenness of the sports ground, caused by soil leakage of the rooting zone layer, is avoided; the requirement on the use of sand in the rooting zone layer is low, and high-quality sand supplied in the general market can be directly taken as the soil for the rooting zone layer; the water storage and drainage plate has drainage and water storage functions, so that the water and fertilizer holding capabilities of the lawn bed of the athletic sports lawn can be enhanced, and the irrigation and the dosage of a fertilizer during the curing of the athletic sports lawn are reduced; and the lawn bed structure is convenient to build, and has low cost and a short construction period.

Description

technical field [0001] The invention relates to a lawn bed structure in the technical field of lawn field construction, in particular to a lawn bed structure for sports fields and golf courses in which storage and drainage boards are integrally laid directly on the soil matrix. Background technique [0002] Sports turf is a living part of the construction of sports venues. Safe, healthy, green and high-quality sports turf can fully protect athletes from injury. In addition, its pleasing lawn landscape is also conducive to attracting sports fans and Spectators, cultivate a healthy and progressive sports market environment. [0003] Our country has a large population and there is a great demand for sports venues. There are more than 2,290 cities above the county level in our country. If each city builds a large-scale standard sports venue with stands, our country will need to build more than 2,290 large-scale sports venues. The stadium has a total sports lawn area of ​​more th...

Problems solved by technology

[0012] The lawn bed structure recommended by the USGA requires absolute compaction of the original soil layer, without the slightest settlement, otherwise it will lead to the movement of the gravel layer, coarse sand layer and rhizosphere layer in the lawn bed in the future, forming a bumpy sports lawn surface, which will seriously affect The movement function of the lawn; the gravel layer, coarse sand layer, and rhizosphere gravel and sand must meet the requirements, and it is possible to maintain the stability of each layer depending on the gap size and particle size between the different layers of sand particles, namely: The particle size of the sand used in the coarse sand layer must be larger than the gaps between the gravels; the particle size of the sand used in the rhizosphere layer must be larger than the gaps between the sand particles in the coarse sand layer, otherwise the sand layer will move down, on the one hand seepage The sand moving down will block the drainage pipes. On the other hand, the moving down of the sand layer will also cause the surface of the lawn to be uneven. As long as there is a small area that is not careful enough or slightly loosened, it may cause the coarse sand to seep into the gravel layer, or the rhizosphere sand to enter the coarse sand layer.

[0013] However, in the actual construction process, sand (particle size 0.25-1.00mm) for the boundary layer, sand (particle size 1.0-4.0mm) and gravel (particle size 4.0-10.0mm) for the coarse sand layer that meet USGA standards Construction materials are hard to find in the market. If you want to use USGA-recommended materials, you need to use screens of different specifications to re-screen the sand and gravel purchased in the market, which is very labor-intensive and expensive.
