Description

Technical Field

[0001] The present invention belongs to the technical field of urban construction, and more specifically, relates to a healthy and ecological sponge city sports landscape structure. Background Art

[0002] Since China has vigorously promoted the construction of sponge cities, the development of Chinese cities has begun to focus on the natural circulation and utilization of urban rainwater. Among them, water storage facilities are essential sponge facilities in sponge city construction and are one of the three important indicators for sponge review. Due to the high engineering cost and large floor area of water storage facilities, if they are set within the basement boundary line, higher requirements are imposed on the existing structure. At the same time, even if some projects have set up water storage facilities, currently, the rainwater is mostly used for irrigation, vehicle washing, and road surface flushing.

[0003] Simply relying on sponge facilities (sunken green spaces or rain barrels) that affect the landscape effect to achieve the water storage volume, the water storage facilities have a large floor area, high engineering cost, high requirements for the existing structure within the basement boundary line, a single rainwater reuse method, no connection with the landscape, and cannot achieve interaction with people. Summary of the Invention

[0004] To solve the problems existing in the prior art, the present invention provides a healthy and ecological sponge city sports landscape structure.

[0005] The technical solution of the present invention is realized as follows:

[0006] A healthy and ecological sponge city sports landscape structure includes a water storage device. The water storage device includes a number of water storage pools installed underground according to requirements; a water inlet pipe and a drain pipe are provided on the water storage device; one-way valves are provided on both the water inlet pipe and the drain pipe, and a maintenance port and a landscape application port are also reserved on the water storage device.

[0007] Further, five water storage pools are provided according to requirements, arranged horizontally at intervals, which are No. 1 water storage pool, No. 2 water storage pool, No. 3 water storage pool, No. 4 water storage pool, and No. 5 water storage pool in sequence. Each water storage pool is provided with a water inlet and a drain; the water inlet pipe is arranged at the water inlet of the No. 1 water storage pool, and the drain pipe is installed at the drain of the No. 5 water storage pool; a connecting pipe is provided between the drain and the water inlet corresponding to any two adjacent water storage pools.

[0008] Further, the inlet end of each connecting pipe is located above the corresponding water storage pool, and the outlet end of each connecting pipe is located below the corresponding water storage pool; the inlet end and the outlet end of the connecting pipe are both open upward, and valve mechanisms are sleeved on both the inlet end and the outlet end of the connecting pipe.

[0009] Further, the valve mechanism includes an annular bracket sleeved on the pipe walls at the inlet end and the outlet end of the connecting pipe. A plurality of support rods are arranged at intervals along the circumferential direction on the annular bracket, and the support rods and the annular bracket form a hollow structure. A cover plate capable of closing the connecting pipe is fixedly connected to the top of the support rods, and limiting blocks are arranged on the pipe walls at the inlet end and the outlet end of the connecting pipe.

[0010] Further, a floating ball is fixedly connected to the top of the cover plate on the valve mechanism at the inlet end of the connecting pipe.

[0011] Further, an exhaust and pressurizing pipe is provided in each reservoir, and a detachable one-way air valve is provided on the exhaust and pressurizing pipe.

[0012] Further, a landscape application port is opened on each reservoir, and an application pipe is provided on each landscape application port; the inlet end of the application pipe is located at the bottom of the corresponding reservoir.

[0013] The construction method of the above structure includes the following steps:

[0014] 1. Excavate the pit; 2. Set a storage device made of a waterproof and airtight material in the pit; 3. Set pipes and valves at the water inlet and outlet, the landscape application port and the landscape exhaust and pressurizing port to ensure that the pipes are tightly connected to the water storage facilities in the pit; 4. Set a sealed and openable maintenance port for convenient future maintenance; 5. Backfill the soil; 6. Connect the landscape exhaust and pressurizing port to the pressurizing facilities in the moving landscape.

[0015] The working principle and effects of the present invention are as follows:

[0016] In this solution: 1. Rainwater flows into the No. 1 reservoir through the infiltration pipe arranged under the permeable road surface. The water inlet pipe is arranged at the water inlet of the No. 1 reservoir, and the drain pipe is installed at the drain outlet of the No. 5 reservoir. One-way valves are provided on both the water inlet pipe and the drain pipe.

[0017] 2. For the reservoirs after the No. 2 reservoir, a connecting pipe is provided between the drain outlet and the water inlet corresponding to any two adjacent reservoirs. The inlet end of each connecting pipe is located on the upper side of the corresponding reservoir, and the outlet end of each connecting pipe is located on the lower side of the corresponding reservoir; valve mechanisms are sleeved on the inlet end and the outlet end of the connecting pipe. The valve mechanism includes an annular bracket sleeved on the pipe walls at the inlet end and the outlet end of the connecting pipe. A plurality of support rods are arranged at intervals along the circumferential direction on the annular bracket, and the support rods and the annular bracket form a hollow structure. A cover plate capable of closing the connecting pipe is fixedly connected to the top of the support rods, and limiting blocks are arranged on the pipe walls at the inlet end and the outlet end of the connecting pipe; a floating ball is fixedly connected to the top of the cover plate on the valve mechanism at the inlet end of the connecting pipe.

[0018] 3. When the water level in the No. 1 reservoir reaches the position of the inlet end of the connecting pipe leading to the No. 2 pool, the floating ball of the valve mechanism rises with the water level, and the cover plate and the annular bracket rise together with the floating ball. Since the annular bracket is a hollow structure, water automatically flows to the outlet end of the connecting pipe, flushing open the cover plate of the valve mechanism at the outlet end, and thus the water in the No. 1 reservoir flows into the No. 2 pool; 4. When the water level in the No. 2 pool reaches the position of the connecting pipe leading to the No. 3 pool, the floating ball will automatically float up, the pipeline opens, and the water automatically flows into the No. 3 pool, and so on; 5. When the water supply from the water source stops and the water level drops below the position of the inlet end of the connecting pipe, the suspended small ball drops, and the cover plate closes the connecting pipe; 6. The number and size of the pools can be set according to the specific needs of the landscape; 7. The drain outlet of the end pool is also provided with a valve mechanism to facilitate the overflow of excess rainwater after the pool is filled with water; 8. In order for rainwater to flow into the pool naturally, a landscape pressure relief vent is set, which can be used for exhaust during the rainy day water injection state. When workers exercise on sunny days, the one-way air valve is removed and connected to the landscape sports pressurization facility, thereby increasing the pressure in the pool and spraying the rainwater from the landscape application port or flowing out in other ways; 9. While people are exercising and entertaining, the vegetation around the landscape is irrigated, adding fun to the exercise and regulating the temperature around the sports landscape; 10. A maintenance port with sealing performance needs to be set at the position of the landscape outlet for convenient future maintenance.

[0019] This solution avoids the way of using sponge facilities (sunken green spaces or rain barrels) that simply affect the landscape effect in sponge city construction to achieve the water storage volume. It has a small floor area, low cost, low structural requirements, and diverse uses for rainwater reuse; it does not affect the landscape beauty and layout; it realizes interaction with people while reusing.

[0020] The water storage facility of this solution has a small floor area, low engineering cost, and does not affect the existing structure even within the basement boundary line. When using the stored rainwater, it can be connected to the landscape sports facilities, thereby adding the interactivity of the landscape, completing irrigation and other entertainment functions while people are exercising and entertaining, and creating a truly ecological sports landscape.

[0028] Embodiment 1

[0029] As Figures 1-3 shown, a healthy ecological sponge city sports landscape structure includes a storage device, and the storage device includes a number of reservoirs installed underground according to requirements; a water inlet pipe 8 and a drain pipe 9 are provided on the storage device; one-way valves are provided on both the water inlet pipe 8 and the drain pipe 9, and an inspection opening 6 and a landscape application opening are also reserved on the storage device.

[0030] There are five reservoirs provided according to requirements, which are arranged at horizontal intervals and are successively the No. 1 reservoir 1, the No. 2 reservoir 2, the No. 3 reservoir 3, the No. 4 reservoir 4, and the No. 5 reservoir 5. Each reservoir is provided with a water inlet and a drain outlet; the water inlet pipe 8 is arranged at the water inlet of the No. 1 reservoir, and the drain pipe 9 is installed at the drain outlet of the No. 5 reservoir; a connecting pipe 10 is provided between the drain outlets and water inlets corresponding to any two adjacent reservoirs.

[0031] The inlet end of each connecting pipe 10 is located above the corresponding reservoir, and the outlet end of each connecting pipe 10 is located below the corresponding reservoir; both the inlet end and the outlet end of the connecting pipe 10 open upward, and valve mechanisms 12 are sleeved on both the inlet end and the outlet end of the connecting pipe 10.

[0032] The valve mechanism 12 includes an annular bracket 15 sleeved on the pipe walls of the inlet end and the outlet end of the connecting pipe 10. A number of support rods 16 are arranged at intervals along the circumferential direction on the annular bracket 15, and the support rods 16 and the annular bracket 15 form a hollow structure; a cover plate 13 capable of closing the connecting pipe 10 is fixedly connected to the top of the support rod 16, and limit catch blocks 17 are arranged on the pipe walls of the inlet end and the outlet end of the connecting pipe 10.

[0033] A floating ball 14 is fixedly connected to the top of the cover plate 13 on the valve mechanism 12 at the inlet end of the connecting pipe 10.

[0034] An exhaust and pressurizing pipe 7 is arranged in each reservoir, and a detachable one-way air valve is arranged on the exhaust and pressurizing pipe 7.

[0035] A landscape application port is opened on each reservoir, and an application pipe 11 is arranged on each landscape application port; the inlet end of the application pipe 11 is located at the bottom of the corresponding reservoir.

[0036] Steps of the construction method: 1. Excavate the pit; 2. Set a water storage device made of waterproof and airtight material in the pit; 3. Set pipelines and valves at the water inlet and outlet, landscape application ports and landscape exhaust and pressurization ports to ensure that the pipelines are tightly connected to the water storage facilities in the pit; 4. Set a sealed and openable maintenance port 6 for convenient future maintenance; 5. Backfill the soil; 6. Connect the landscape exhaust and pressurization port to the pressurization facilities in the sports landscape.

[0037] In this scheme, rainwater flows into the No. 1 reservoir through the infiltration pipe arranged under the permeable road surface. The water inlet pipe 8 is arranged at the water inlet of the No. 1 reservoir, and the drain pipe 9 is installed at the drain outlet of the No. 5 reservoir. One-way valves are arranged on both the water inlet pipe 8 and the drain pipe 9;

[0038] For the water pools after Pool 2, a connecting pipe 10 is provided between the drainage outlets and water inlets corresponding to any two adjacent reservoirs. The inlet end of each connecting pipe 10 is located on the upper side of the corresponding reservoir, and the outlet end of each connecting pipe 10 is located on the lower side of the corresponding reservoir; valve mechanisms 12 are sleeved on both the inlet end and the outlet end of the connecting pipe 10. The valve mechanism 12 includes an annular bracket 15 sleeved on the pipe walls of the inlet end and the outlet end of the connecting pipe 10. A number of support rods 16 are arranged at intervals along the circumferential direction on the annular bracket 15. The support rods 16 and the annular bracket 15 form a hollow structure; a cover plate 13 that can seal the connecting pipe 10 is fixedly connected to the top of the support rod 16. Limiting blocks 17 are provided on the pipe walls of both the inlet end and the outlet end of the connecting pipe 10; a floating ball 14 is fixedly connected to the top of the cover plate 13 on the valve mechanism 12 located at the inlet end of the connecting pipe 10;

[0039] When the water level in Reservoir 1 reaches the position of the inlet end of the connecting pipe 10 leading to Pool 2, the floating ball 14 of the valve mechanism 12 rises with the water level, and the cover plate 13 and the annular bracket 15 rise together with the floating ball 14. Since the annular bracket 15 is a hollow structure, water automatically flows to the outlet end of the connecting pipe 10, flushing open the cover plate 13 of the valve mechanism 12 at the outlet end. Thus, the water in Reservoir 1 flows into Pool 2; 4. When the water level in Pool 2 reaches the position of the connecting pipe 10 leading to Pool 3, the floating ball 14 will automatically float up, the pipeline opens, and water automatically flows into Pool 3, and so on; 5. When the water source stops supplying water and the water level drops to a position below the inlet end of the connecting pipe 10, the suspended small ball drops, and the cover plate 13 seals the connecting pipe 10;

[0040] The number and size of the water pools can be set according to the specific needs of the landscape;

[0041] A valve mechanism 12 is also provided at the drainage outlet of the terminal water pool, which is convenient for ensuring that the excess rainwater can overflow after the water pool is filled with water;

[0042] In order for rainwater to flow into the pool naturally, a landscape pressure relief vent is provided, which can be used for exhaust during the rainy day water injection state. When workers exercise on sunny days, the one-way air valve is removed and connected to the landscape exercise pressure facility, thereby increasing the pressure in the water pool, and spraying the rainwater from the landscape application port or flowing out in other ways;

[0043] While people are exercising and having fun, the irrigation of the vegetation around the landscape is completed, adding fun to the exercise and regulating the temperature around the exercise landscape.

[0044] An inspection port 6 with sealing performance needs to be set at the landscape water outlet position to facilitate future maintenance.

[0045] This solution avoids the method of achieving water storage volume solely by sponge facilities (sunken green spaces or rain barrels) that affect the landscape effect in sponge city construction. It has a small footprint, low cost, low structural requirements, and diverse uses for rainwater reuse; it does not affect the landscape aesthetic and layout; and it enables interaction with people while reusing rainwater.

[0046] The water storage facility of this solution occupies a small area, has a low engineering cost, and does not affect the existing structure even within the basement boundary line. Moreover, when using the stored rainwater, it can be connected to landscape sports facilities, thereby enhancing the interactivity of the landscape and completing irrigation and other entertainment functions while people are engaged in sports and entertainment, creating a truly ecological sports landscape.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
