Description

Technical Field

[0001] The utility model relates to the field of artificial turf, in particular to a spliced ​​water storage courtyard lawn. Background Art

[0002] Artificial turf is a chemical product made by embedding blade-like synthetic fibers onto a woven base fabric and coating the back with a retaining coating to create a natural grass-like surface. It is widely used in sports and leisure venues. In hot weather, artificial turf requires manual watering to cool it down, which not only increases labor costs but also consumes a large amount of water resources. To address this problem, self-cooling artificial turfs have emerged on the market. For example, Chinese patent CN209493787U discloses a recyclable artificial turf with a water storage function and a water storage turf facility. While this water storage function can achieve a cooling effect, the base fabric layer is a single piece. If a problem occurs with some of the grass strands, the entire turf must be replaced, rather than just replacing parts of it.

[0003] Therefore, there is an urgent need for a courtyard lawn that can store water and cool down and can be partially replaced. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features therein can be combined with each other.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0027] Example 1

[0028] This embodiment provides a spliced ​​water storage courtyard lawn, comprising: a functional layer 1, a support layer 2 fixedly connected to the top of the functional layer 1, and a plurality of turf layers 3 detachably connected to the top of the support layer 2; wherein,

[0029] The functional layer 1 is made of a water-permeable material; a placement groove is provided at the top of the functional layer 1, and a water storage portion 11 is provided in the placement groove. The outer wall of the water storage portion 11 is in contact with the inner wall of the placement groove, and the top of the outer wall of the water storage portion 11 is not higher than the top of the groove wall of the placement groove. The inner wall of the water storage portion 11 is provided with a waterproof coating; a cross-shaped support rod 111 is also provided in the middle of the top of the water storage portion 11.

[0030] The support layer 2 is made of a water-permeable material; a plurality of turf placement grooves 21 are provided on the top of the support layer 2; a first magnetic sheet is provided in each of the plurality of turf placement grooves 21;

[0031] The turf layer 3 includes: a limiting portion 31 and a grass wire portion 32 fixedly connected to the top of the limiting portion 31; the limiting portion 31 matches the turf placement groove 21, and the bottom end of the limiting portion 31 is provided with a second magnetic sheet matching the first magnetic sheet, and several turf layers 3 are connected to the supporting layer 2 through the cooperation and disassembly of the first magnetic sheet and the second magnetic sheet; the top of the grass wire portion 32 is provided with several artificial grass wires 321; and several water-permeable holes are opened on the turf layer 3.

[0032] When paving, the bottom of the functional layer 1 is in contact with the ground; when it rains, rainwater flows through the permeable holes on the turf layer 3 to the supporting layer 2.

Since the top of the outer wall of the water storage part 11 is not higher than the top of the groove wall of the placement groove, when the rainwater in the water storage part 11 is full, the excess rainwater will seep into the functional layer 1 through the top of the groove wall of the placement groove and then be discharged. When the weather is hot, the rainwater in the water storage part 11 The cooling effect can be achieved by evaporation and heat absorption; when the turf layer 3 needs to be replaced, the user can separate the turf layer 3 to be replaced from the supporting layer 2 and replace it with a new turf layer 3. The limiting portion 31 of the turf layer 3 matches the turf placement groove 21, so that the user can install the turf layer 3 and the supporting layer 2 without spending time on alignment operations; in addition, the grass thread portion 32 is larger than the limiting portion 31, so that the grass thread portion 32 can cover the top protrusion of the turf placement groove 21, thereby achieving an aesthetic effect.
