Description

Technical Field

[0001] This invention relates to the field of football field drainage technology, and in particular to an outdoor artificial turf football field with good drainage performance and its construction method. Background Technology

[0002] Football field turf is a type of grass specifically designed and planted for football matches and training. It typically requires good density, durability, and resilience to withstand the high-intensity activities of matches and daily use.

[0003] In rainy weather, football fields are prone to water accumulation due to the poor permeability of the foundation surface. Under the influence of rainwater and the grass, athletes are easily slipped and injured, which also affects the progress of the game. At the same time, because football fields are relatively large, they can retain a lot of water. After rain, existing football fields generally need to be drained for 2-3 hours, which can easily lead to water accumulation on the grass surface. Moreover, the practice of draining all the water at once is not conducive to the reuse of water resources. Summary of the Invention

[0004] The technical problem to be solved by this invention is that after rain, existing football fields generally require 2-3 hours to drain water, which easily leads to water accumulation on the surface of the grass. Moreover, the practice of draining all the water at once is not conducive to the reuse of water resources.

[0005] To solve the above technical problems, the present invention provides the following technical solution: an outdoor artificial turf football field with good drainage includes a turf layer, an elastic layer, a filling layer, a shock-absorbing layer and a base layer arranged from top to bottom. The bottom of the base layer is fixedly connected to the top of the support column, and the bottom of the support column is fixedly connected to the support layer. A drainage ditch is provided at the edge of the support layer, and the drainage channel is connected to the collection component through a first connecting pipe.

[0006] The collection assembly includes a collection tank, a drain pipe, an irrigation pipe, a pump system, and a T-joint. The top of the collection tank is connected to a first connecting pipe, and the bottom of the collection tank is connected to one port of the T-joint via the pump system. The other two ports of the T-joint are connected to the drain pipe and the irrigation pipe, respectively. The drain pipe is used for draining water, and the irrigation pipe is used for irrigating the turf layer.

[0007] The height of the middle part of the support layer is higher than that of the edge.

[0008] Preferably, the drainage pipe and irrigation pipe are provided with an adjusting pipe, the inner wall of the adjusting pipe is slidably connected to a piston column, the top of the piston column is fixedly connected to the bottom of a first telescopic rod, and the movable end of the first telescopic rod passes through the top of the adjusting pipe.

[0009] Preferably, the outer wall of the collection tank is fixedly connected to the housing, the pump system, the tee, the regulating pipe and the first telescopic rod are located inside the housing, and the top of the first telescopic rod is fixedly connected to the top wall of the housing.

[0010] Preferably, a fixing ring is fixedly connected to the inner wall of the collection tank, and multiple fixing rings are arranged vertically. A movable tube is slidably connected to the inner wall of the fixing ring, and the movable tube is hollow inside. A second telescopic rod is provided at the top of the movable tube, and the second telescopic rod is connected to the first telescopic rod through a second connecting tube.

[0011] Preferably, a spring is fitted on the movable end of the second telescopic rod, with one end of the spring abutting against the fixed end of the second telescopic rod and the other end of the spring abutting against the collection tank.

[0012] Preferably, frustums are fixedly installed at both ends of the movable tube.

[0013] Preferably, the turf layer, elastic layer, filling layer, shock-absorbing layer, and base layer are provided with through holes. A movable block composed of the turf layer, elastic layer, filling layer, shock-absorbing layer, and base layer is slidably arranged on the inner wall of the through hole. A cylinder is fixedly connected to the bottom of the movable block, a support layer is fixedly connected to the bottom of the cylinder, and a load-bearing ring is fixedly connected to the base layer at the bottom of the through hole. The end of the irrigation pipe away from the collection tank is fixedly connected to the bottom of the movable block and the top of the cylinder, and a nozzle is installed on the irrigation pipe.

[0014] Preferably, a mesh cover is provided on the outer side of the movable block and the inner wall of the through hole.

[0015] This invention provides a construction method for an outdoor artificial turf soccer field with good drainage, wherein:

[0016] Step S1: First, dig a foundation pit at the lawn location, compact the bottom of the foundation pit, and then harden the bottom and inner walls of the foundation pit with concrete.

[0017] Step S2: Install the collection tank on the foundation pit, and install the corresponding drainage pipe, irrigation pipe, pump system and tee.

[0018] Step S3: Place square pipes at the edge of the support layer in advance, construct the support layer above the collection tank using cast-in-place concrete, and remove the square pipes. The square pipes form a drainage ditch. The height of the middle part of the support layer is higher than the edge, and its slope is between 0.5% and 1%.

[0019] Step S4: Construct support columns on the support layer, with a spacing of less than 1m between the support columns;

[0020] Step S5: Lay the foundation layer above the support column. The foundation layer is first poured with concrete, and then crushed stone is laid on top.

[0021] Step S6: Lay the shock-absorbing layer, filling layer, elastic layer and turf layer in sequence on the base layer;

[0022] The shock-absorbing layer uses foam pads, the filling layer uses quartz sand, the elastic layer uses SBR or TPE rubber granules, and the turf layer uses either natural grass or artificial grass.

[0023] The beneficial effects of this invention are:

[0024] In this invention, after rainwater falls on the turf layer, it permeates through the turf layer, elastic layer, filling layer, shock-absorbing layer, and base layer before falling onto the support layer. During this process, impurities and pollutants in the water are intercepted layer by layer, the water is filtered, and it converges into the drainage ditch set at the edge of the support layer. The water in the drainage ditch enters the collection tank through the first connecting pipe. The collection tank can temporarily store water, which facilitates the rapid drainage of water accumulated on the turf layer.

[0025] Water from the collection tank flows through a pump system and T-joints into drainage and irrigation pipes, respectively. The drainage pipe is used for drainage, and the irrigation pipe is used for irrigating the turf layer. The pump system is a combination of a vacuum pump and a water pump. The vacuum pump is responsible for removing air, and the water pump is responsible for removing water. The vacuum pump and water pump are connected in parallel, and electric control valves are installed at both ends of the vacuum pump and water pump. When there is water accumulation above the support layer, the water pump is activated, and the electric control valves at both ends of the water pump are opened, while the electric control valves at both ends of the vacuum pump are closed. This allows the water in the support layer to be removed. Then, the water pump is shut down, and the electric control valves at both ends of the water pump are closed. The vacuum pump is activated, and the electric control valves at both ends of the vacuum pump are opened. At this time, the vacuum pump is working, removing some of the air between the base layer and the support layer, creating negative pressure. This accelerates the infiltration of rainwater through the turf layer, elastic layer, infill layer, shock-absorbing layer, and base layer, allowing the accumulated water to drain quickly.

[0026] The system can operate in two modes: irrigation and drainage. The water level in the collection tank is the determining factor, and the system is automatically controlled by the water level without any additional operation. When the irrigation pipe is open, it can be used to irrigate the turf layer. It can also collect rainwater, save water resources, and help protect the environment. Attached Figure Description

Detailed Implementation

[0037] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0038] Example 1, referring to Figures 1-3 This embodiment provides an outdoor artificial turf soccer field with good drainage, including a turf layer 101, an elastic layer 102, a filling layer 103, a shock-absorbing layer 104 and a base layer 105 arranged from top to bottom. The bottom of the base layer 105 is fixedly connected to the top of the support column 106, and the bottom of the support column 106 is fixedly connected to the support layer 107. The edge of the support layer 107 is provided with a drainage ditch 108, and the drainage ditch 108 is connected to the collection assembly 2 through a first connecting pipe 109.

[0039] The collection component 2 includes a collection tank 201, a drain pipe 202, an irrigation pipe 203, a pump system 204, and a T-joint 205. The top of the collection tank 201 is connected to a first connecting pipe 109, and the bottom of the collection tank 201 is connected to one port of the T-joint 205 through the pump system 204. The other two ports of the T-joint 205 are connected to the drain pipe 202 and the irrigation pipe 203, respectively. The drain pipe 202 is used for drainage, and the irrigation pipe 203 is used for irrigating the turf layer 101.

[0040] The shock-absorbing layer 104 uses foam padding to cushion and absorb shocks. The infill layer 103 uses quartz sand, which provides support while allowing water permeability and trapping impurities carried in the water. The elastic layer 102 uses SBR or TPE rubber granules, providing additional cushioning and a uniform feel underfoot. The turf layer 101 uses either natural grass or artificial grass, providing a surface, appearance, and feel for sports activities. The natural grass blades are selected from resilient and resilient species, such as perennial ryegrass and tall fescue, and are often mixed species. A grass mat layer is placed beneath the natural grass, located between the grass blades and the soil layer, and is composed of living and dead roots and runners. A healthy grass mat layer enhances the elasticity and durability of the lawn, and the elastic layer 102 is placed below the soil layer. The base layer 105 is first cast-in-place with concrete, and then gravel is laid on top to provide support. Water can permeate through the base layer 105. Multiple holes, less than 2 cm in diameter, can be drilled in the base layer 105 to form an array, increasing the water's ability to pass through. In one embodiment, to further enhance water filtration, a layer of bamboo charcoal is laid in the middle of the filling layer 103, forming a bamboo charcoal layer to increase the filtration of pollutants and impurities in the water.

[0041] Multiple support columns 106 are provided, forming a rectangular array to support the base layer 105. After rain, rainwater falling on the turf layer 101 seeps through the turf layer 101, elastic layer 102, filling layer 103, shock-absorbing layer 104, and base layer 105 before falling onto the support layer 107. During this process, impurities and pollutants in the water are intercepted layer by layer, the water is filtered, and it collects in the drainage ditch 108 set at the edge of the support layer 107. The water in the drainage ditch 108 enters the collection tank 201 through the first connecting pipe 109. The collection tank 201 can temporarily store water, which facilitates the rapid drainage of water accumulated on the turf layer 101.

[0042] The collection assembly is used to collect rainwater, and the collection tank 201 can also be composed of multiple small collection tanks combined into a large collection tank 201. The water in the collection tank 201 enters the drain pipe 202 and the irrigation pipe 203 through the pump system 204 and the T-joint 205, respectively. The drain pipe 202 is used for drainage, and the irrigation pipe 203 is used for irrigating the turf layer 101. Pump system 204 is a combination of a vacuum pump and a water pump. The vacuum pump is responsible for extracting air, and the water pump is responsible for extracting water. The vacuum pump and the water pump are connected in parallel, and electric control valves are installed at both ends of the vacuum pump and the water pump. When there is water accumulation above the support layer 107, the water pump is started, and the electric control valves at both ends of the water pump are opened, while the electric control valves at both ends of the vacuum pump are closed. This allows the water accumulation in the support layer 107 to be extracted. Then, the water pump is turned off, and the electric control valves at both ends of the water pump are closed. The vacuum pump is then turned on, and the electric control valves at both ends of the vacuum pump are opened. At this time, the vacuum pump is working, extracting some of the air between the base layer 105 and the support layer 107, creating negative pressure. This accelerates the infiltration of rainwater through the turf layer 101, elastic layer 102, filling layer 103, shock-absorbing layer 104, and base layer 105, allowing the accumulated water to be drained quickly.

[0043] Reference Figure 1 The height of the middle part of the support layer 107 is higher than that of the edge.

[0044] The middle part of the support layer 107 is higher than the edge, and its slope is between 0.5% and 1%, which facilitates the guidance of water accumulated on the support layer 107 into the drainage ditch 108.

[0045] Reference Figures 3-5 An adjusting pipe 206 is provided on the drainage pipe 202 and the irrigation pipe 203. A piston column 207 is slidably connected to the inner wall of the adjusting pipe 206. The top of the piston column 207 is fixedly connected to the bottom of the first telescopic rod 208. The movable end of the first telescopic rod 208 passes through the top of the adjusting pipe 206.

[0046] The regulating pipe 206 is used to control the opening or closing of the drainage pipe 202 and the irrigation pipe 203. When the first telescopic rod 208 extends, it drives the piston rod 207 to move downwards, and the piston rod 207 moves to... Figure 5 At this position, the drain pipe 202 is open and the irrigation pipe 203 is closed. When the first telescopic rod 208 retracts, it drives the piston rod 207 to move upward, and the piston rod 207 moves to the middle position. Figure 4 At this point, the drain pipe 202 is closed and the irrigation pipe 203 is open.

[0047] In one embodiment, sealing rings are installed at both ends of the piston rod 207, which helps to improve the sealing between the piston rod 207 and the inner wall of the regulating tube 206. During installation, the top of the regulating tube 206 is cut open, the piston rod 207 is inserted into the regulating tube 206, and then the tops of the regulating tube 206 are welded together to form a complete unit.

[0048] Reference Figure 2 and Figure 3 The outer wall of the collection tank 201 is fixedly connected to the housing 209. The pump system 204, the three-way head 205, the regulating pipe 206 and the first telescopic rod 208 are located inside the housing 209, and the top of the first telescopic rod 208 is fixedly connected to the top wall of the housing 209.

[0049] The housing 209 provides protection for the pump system 204, the tee head 205, the regulating pipe 206 and the first telescopic rod 208. At the same time, the housing 209 can fix the fixed end at the top of the first telescopic rod 208.

[0050] Reference Figure 3 and Figure 6 The inner wall of the collection tank 201 is fixedly connected to a fixing ring 301, and multiple fixing rings 301 are arranged vertically. The inner wall of the fixing ring 301 is slidably connected to a movable tube 302, and the movable tube 302 is hollow inside. A second telescopic rod 303 is provided at the top of the movable tube 302, and the second telescopic rod 303 is connected to the first telescopic rod 208 through a second connecting tube 304.

[0051] The movable tube 302 is a hollow metal tube and can be manufactured using existing metal tube sealing technology. The movable tube 302 can slide up and down the inner wall of the fixed ring 301. When there is no water inside the collection tank 201, the movable tube 302 is located at the bottom wall of the collection tank 201. When there is water inside the collection tank 201, the movable tube 302 rises under the buoyancy of the water, pushing the second telescopic rod 303 to compress. At this time, the hydraulic oil inside the second telescopic rod 303 enters the first telescopic rod 208 through the second connecting pipe 304, causing the first telescopic rod 208 to extend. The first telescopic rod 208 drives the piston rod 207 to move downwards. Figure 5 At this position, the drain pipe 202 is open and the irrigation pipe 203 is closed, draining water into the sewer or a pre-dug drainage pool. When there is not enough water in the collection tank 201, the buoyancy of the water causes the movable pipe 302 to rise. When the movable pipe 302 is insufficient to compress the second telescopic rod 303, the hydraulic oil inside the first telescopic rod 208 enters the second telescopic rod 303 through the second connecting pipe 304. At this time, the first telescopic rod 208 retracts, and the first telescopic rod 208 drives the piston column 207 to move upward. The piston column 207 moves to... Figure 4At this position, the drain pipe 202 is closed and the irrigation pipe 203 is open, which can be used to irrigate the turf layer 101, and can collect rainwater, thus saving water resources. The two states of irrigation or drainage are determined by the water level in the collection tank 201, which is automatically controlled by the water level without additional operation. Moreover, the opening of the irrigation pipe 203 can be used to irrigate the turf layer 101, collect rainwater, save water resources, and is beneficial to environmental protection.

[0052] Reference Figure 6 A spring 305 is fitted on the movable end of the second telescopic rod 303, with one end of the spring 305 abutting against the fixed end of the second telescopic rod 303 and the other end of the spring 305 abutting against the collection tank 201.

[0053] When there is water inside the collection tank 201, the movable tube 302 rises under the buoyancy of the water, pushing the second telescopic rod 303 to compress. At this time, the elastic force of the spring 305 is overcome, and the hydraulic oil inside the second telescopic rod 303 enters the first telescopic rod 208 through the second connecting pipe 304. The first telescopic rod 208 extends, driving the piston rod 207 to move downwards. The piston rod 207 moves to... Figure 5 At this position, the drain pipe 202 is open and the irrigation pipe 203 is closed, draining water into the sewer or a pre-dug drainage pool. When there is not enough water in the collection tank 201, the buoyancy of the water causes the movable pipe 302 to rise. When the movable pipe 302 is insufficient to compress the second telescopic rod 303, the second telescopic rod 303 extends under the elastic force of the spring 305. The hydraulic oil inside the first telescopic rod 208 enters the second telescopic rod 303 through the second connecting pipe 304. At this time, the first telescopic rod 208 retracts, driving the piston rod 207 to move upward. The piston rod 207 moves to... Figure 4 At this point, the drainage pipe 202 is closed and the irrigation pipe 203 is open, which can be used to irrigate the turf layer 101, and can collect rainwater to save water resources.

[0054] Reference Figure 6 The movable tube 302 has a frustum 306 fixedly installed at both ends.

[0055] The frustum 306 facilitates the alignment of the movable tube 302 with the fixed ring 301, thereby allowing the movable tube 302 to slide up and down on the inner wall of the fixed ring 301.

[0056] Reference Figure 7 and Figure 8Through holes 1 are provided in the turf layer 101, elastic layer 102, filling layer 103, shock-absorbing layer 104 and base layer 105. A movable block 21 composed of the turf layer 101, elastic layer 102, filling layer 103, shock-absorbing layer 104 and base layer 105 is slidably installed on the inner wall of the through hole 1. A cylinder 3 is fixedly connected to the bottom of the movable block 21. A support layer 107 is fixedly connected to the bottom of the cylinder 3. A load-bearing ring 4 is fixedly connected to the base layer 105 at the bottom of the through hole 1. The end of the irrigation pipe 203 away from the collection tank 201 is fixedly connected to the bottom of the movable block 21 and the top of the cylinder 3. A nozzle 5 is installed on the irrigation pipe 203.

[0057] When cylinder 3 extends, it moves the movable block 21, composed of the turf layer 101, elastic layer 102, filling layer 103, shock-absorbing layer 104, and base layer 105, upward, and moves the nozzle 5 upward. Once the nozzle 5 is above ground level, water from the irrigation pipe 203 is sprayed out through the nozzle 5 to irrigate the turf layer 101. When cylinder 3 retracts, it moves the movable block 21 downward, with the base layer 105 resting on the support ring 4. The support ring 4 supports the movable block 21. In one embodiment, a sealing ring is provided on the support ring 4. After the base layer 105 rests on the support ring 4, it isolates the air between the base layer 105 and the support ring 4, thus sealing the block.

[0058] Reference Figure 7 and Figure 8 A mesh cover 6 is provided on the outer side of the movable block 21 and the inner wall of the through hole 1.

[0059] The netting 6 can prevent the filling particles or soil in the turf layer 101, elastic layer 102, filling layer 103, and shock-absorbing layer 104 from leaking out.

[0060] Example 2, refer to Figure 1-9 This embodiment is based on the previous embodiment, but differs from the previous embodiment in that it further includes:

[0061] Step S1: First, dig a foundation pit at the lawn location, compact the bottom of the foundation pit, and then harden the bottom and inner walls of the foundation pit with concrete. Waterproof the inner and bottom walls of the foundation pit and apply an air barrier coating, such as an ethylene-vinyl alcohol copolymer (EVOH) based membrane air barrier coating, to form a sealed environment.

[0062] Step S2: Install the collection tank 201 on the foundation pit, and install the corresponding drainage pipe 202, irrigation pipe 203, pump system 204 and tee 205;

[0063] Step S3: Place square pipes at the edge of the support layer 107 in advance, construct the support layer 107 above the collection tank 201 using concrete casting, and remove the square pipes. The position of the square pipes forms a drainage ditch 108. The height of the middle part of the support layer 107 is higher than the edge, and its slope is between 0.5% and 1%.

[0064] Step S4: Construct support columns 106 on the support layer 107, with the interval between support columns 106 being less than 1m;

[0065] Step S5: Lay a foundation layer 105 above the support column 106. The foundation layer 105 is first poured with concrete, and then crushed stone is laid on top.

[0066] Step S6: Lay the shock-absorbing layer 104, the filling layer 103, the elastic layer 102 and the turf layer 101 sequentially on the base layer 105;

[0067] Among them, the shock-absorbing layer 104 is made of foam pad, the filling layer 103 is made of quartz sand, the elastic layer 102 is made of SBR or TPE rubber granules, and the turf layer 101 is made of either natural grass or artificial grass.

[0068] Water in collection tank 201 enters drainage pipe 202 and irrigation pipe 203 through pump system 204 and T-joint 205 respectively. Drainage pipe 202 is used for drainage, and irrigation pipe 203 is used for irrigating turf layer 101. Pump system 204 is a combination of a vacuum pump and a water pump. The vacuum pump is responsible for extracting air, and the water pump is responsible for extracting water. The vacuum pump and the water pump are connected in parallel, and electric control valves are installed at both ends of the vacuum pump and the water pump. When there is water accumulation above the support layer 107, the water pump is started, and the electric control valves at both ends of the water pump are opened, while the electric control valves at both ends of the vacuum pump are closed. This allows the water accumulation in the support layer 107 to be extracted. Then, the water pump is turned off, and the electric control valves at both ends of the water pump are closed. The vacuum pump is then turned on, and the electric control valves at both ends of the vacuum pump are opened. At this time, the vacuum pump is working, extracting some of the air between the base layer 105 and the support layer 107, creating negative pressure. This accelerates the infiltration of rainwater through the turf layer 101, elastic layer 102, filling layer 103, shock-absorbing layer 104, and base layer 105, allowing the accumulated water to be drained quickly.

[0069] The irrigation or drainage mode is determined by the water level in the collection tank 201 and is automatically controlled by the water level without any additional operation. Moreover, when the irrigation pipe 203 is opened, it can be used to irrigate the turf layer 101, which can recycle rainwater, save water resources, and help protect the environment.
