Problems solved by technology

However, the drainage pipes under the sports lawn bed are generally separated by about 5 meters, and the lawn temperature control effect between adjacent pipes is different from that of the lawn above the pipes. The temperature control effect of the lawn above the drainage pipes is better, and the soil temperature is more suitable. It can maintain a certain growth, but the lawn between one or two adjacent drainage pipes is basically difficult to be radiated by the temperature control effect. The farther away from the drainage pipe, the worse the temperature control effect. This temperature gradient will cause the lawn to grow. Severe unevenness and variation in turf color, affecting the sporting quality and landscape quality of the turf

Embodiment 1

[0029] Such as figure 1 and figure 2 As shown, the temperature control system of the lawn bed in this embodiment is composed of the drainage ditch area and the original soil layer area, and a part is the drainage ditch area, including the main drainage pipe 10 and the branch drainage pipe 11 distributed in the form of fish ridges under the lawn bed. The drainage pipe 5 system, the gravel 7 filled around the pipe and the water storage board 4 laid horizontally above; the other part is the original soil layer area, including the non-woven fabric 3 and the water storage board 6 laid horizontally under the rhizosphere soil of the lawn . The port of the main drainage pipe 10 is connected with the air outlet of the air conditioning unit 9, and the cold and warm air flow of the air conditioning system enters the concavo-convex space connected in the storage and drainage plate 6 through the holes on the drainage pipe 5 wall and forms a stable control system under the lawn bed. The ...

Embodiment 2

[0040] Football field sports lawn:

[0041] The sports lawn of a standard football field is 109 meters long and 72 meters wide. Drainage ditches are laid around the football field and covered with boards. Drainage ditches are opened on the foundation, and the drainage ditches are distributed in the shape of fish ridges. There is a main drainage ditch in the middle of the field, and side drainage ditches on both sides. ditch connected. The drainage ditch is excavated into a shape with a wide top and a narrow bottom, and the side slope of the drainage ditch is 30 degrees. The double-sided concave-convex storage and drainage board with a compressive strength of more than 200kPa directly bonded to the non-woven fabric is directly laid on the compacted original soil layer, and the joint is kept with two rows of concave-convex holes overlapped and joined. The storage and drainage board is directly laid into the drainage ditch, so that the base of the flat bed forms the whole of t...

Abstract

The invention discloses a regulation structure for temperature of a lawn bed and a construction method thereof, belonging to the field of building greening technology. The regulation structure comprises a drainage channel area and an original soil layer area, wherein the drainage channel area comprises drainage pipelines in fish fillet-shape or parallel distribution below the lawn bed, gravel filled around the pipelines and a water storage plate horizontally paved above; and the original soil layer area comprises a non-woven fabric horizontally paved below the lawn rhizosphere layer soil and a water storage / drainage plate. A port of each drainage pipeline is connected with an air outlet of an air conditioning system; cold / warm air flow of the air conditioning system enters the communicated concave / convex space in the water storage / drainage plate through holes on the wall of the drainage pipelines, and forms a stable temperature control layer below the lawn bed; and the cold / warm air flow enters the rhizosphere layer through gaps of the non-woven fabric to regulate the temperature of the rhizosphere layer. The regulation structure disclosed by the invention is suitable for various types of sports lawn and garden greening lawn such as golf course, football pitch and the like, and can regulate the bottom temperature of the lawn at a constant temperature.

Description

technical field [0001] The invention relates to a structure in the technical field of building greening, in particular to a lawn bed temperature control structure and a construction method thereof. Background technique [0002] The growth of lawn plants requires a suitable temperature. The optimum growth temperature of creeping bentgrass, bluegrass, tall fescue and other cool-season turf plants is 15-20℃. Under the condition of temperature >30℃ in summer, the growth of cool-season turf is inhibited, manifested as a significant decrease in photosynthesis and energy synthesis, while respiration increases and energy consumption increases, showing the energy deficit of plants. At this time, the physique of the lawn plants gradually weakens, the tillers will gradually die, the density of the lawn will decrease, and the quality of the lawn will decline. At the same time, due to the insufficient energy supply in the plant, the ability to resist adversity will decline significan...
