Embodiment 1

[0026] Embodiment 1: The construction structure of garden landscape lawn bed is as follows figure 1 shown. The method generally has an inverted umbrella-shaped radial structure, and module combinations can be carried out according to the actual area, including the evaporation section 1 vertically inserted into the shallow soil 7 of the lawn, the condensation section 2 laid on the lawn rhizosphere layer 5, and the connecting evaporation section 1 The thermal insulation section 3 of the condensing section 2 and the thermal insulation layer 4 surrounding the thermal insulation section 3 . The evaporating section 1 is a single straight pipe structure with a length of 2m and an aspect ratio of 100. Its upper part communicates with the lower part of the adiabatic section 3. The length of the adiabatic section 3 is 3m. The inclination angle between the condensing section 2 and the platform bed is 10°. Its lower part communicates with the upper part of the thermal insulation section ...

Embodiment 2

[0028] Embodiment two: the lawn bed construction structure of the football field is as figure 2 and 3shown. In the present embodiment, the method is generally made and laid as a multi-pipeline form according to the standard football field lawn size (long 109m, wide 72m), and the condensing section 2 is horizontally paved, and the specific layout is as follows figure 2 As shown, the evaporation section 1 is a serpentine structure with a length of 3m and an aspect ratio of 100. It is inserted vertically into the soil. The length of the thermal insulation section 3 is 3m. image 3 As shown, its working form and construction method are the same as those in Embodiment 1, which can ensure that the temperature of the rhizosphere layer of the flat bed is maintained at 5-6°C.

Embodiment 3

[0029] Embodiment three: the construction structure of the green lawn bed of the golf course is as follows Figure 4 and 5 shown. In this embodiment, the method is based on the characteristics of the ups and downs of the green lawn of the golf course, and the main branch pipeline structure is laid at different angles according to the overall terrain. The layout of the condensation section 2 is as follows Figure 4 As shown, the evaporation section 1 is a spiral structure with a length of 2m and an aspect ratio of 70. It is installed vertically with the lawn bed of the green. The length of the heat insulation section 3 is 2m. The overall structural section of the lawn bed is shown in Figure 5 As shown, its working form and construction method are the same as those in Embodiment 2, which can ensure that the temperature of the rhizosphere layer of the flat bed is maintained at 5-6°C.

Abstract

The invention relates to a method for constructing a turf bed by utilizing shallow geothermal energy, which is characterized in that a device for green protection and temperature control of a lawn by utilizing shallow geothermal energy is arranged under a rhizosphere layer of the turf bed of the lawn; the device is arranged under the rhizosphere layer of the turf bed of the lawn; the device comprises an evaporation segment inserted to the shallow soil of the lawn, a condensation segment paved under the rhizosphere layer of the lawn, a heat insulating segment and a heat insulating layer arranged outside the heat insulating segment; a communicated and closed space is formed inside the device, and the closed space is vacuumized and filled with a liquid working medium; and low-grade geothermal energy is absorbed from the shallow soil of the lawn by the liquid medium in the evaporation segment, vaporized to form vapor and transferred to the condensation segment through the heat insulating segment and releases heat, a vapor medium is condensed into a liquid when meeting cold air and reflows to the evaporation segment again through the heat insulating segment, and all the steps are repeatedly circulated. By using the method, the temperature control for the rhizosphere layer of the turf bed of the lawn is effectively realized, the vegetation on the turf bed is kept evergreen, and the function period of the lawn in winter is prolonged.

Description

technical field [0001] The invention relates to a lawn bed construction method using shallow geothermal energy, which can make the lawn bed in different occasions such as landscape, football, golf, etc. have the characteristic of keeping warm in winter, and belongs to the technical field of lawn construction. Background technique [0002] Lawn growth is greatly affected by temperature changes in four seasons. When the temperature is lower than 5°C in winter, cool-season lawns will also enter a dormant state, and the growth of plant buds and the occurrence of new leaves will gradually stop. Under the action of cold air and cold air, it gradually withers and turns yellow, which seriously affects the landscape quality of the lawn and the ecological function of soil fixation and sand prevention. With the improvement of people's living standards, it is hoped that lawns can maintain a green landscape and ecological functions throughout the year, especially sports lawns have very s...
