Description

Technical Field

[0001] The invention belongs to the field of highway supporting facilities, and in particular relates to a highway water reservoir. Background Art

[0002] Currently, drainage on highways primarily relies on installing evaporation ponds near the highways or wide, shallow side ditches along the highway slopes. Rainwater and snowmelt from the highway pavement and slopes drain down the slopes into the ditches or evaporation ponds. However, much of the water discharged into the ditches and evaporation ponds evaporates and is not effectively utilized. Furthermore, the construction of evaporation ponds requires a large area of ​​land, sometimes even valuable arable land, which is detrimental to the utilization of land resources. In areas with heavy rainfall, relying solely on slopes and evaporation ponds is insufficient to cope with the drainage pressure brought on by heavy rainfall.

[0003] In addition, the slope greening along the highway, service areas and sprinkler trucks and cleaning vehicles used in highway maintenance all require a large amount of water. If the water discharged into the slope or evaporation pond can be concentrated and used, it will greatly alleviate the problem of water resource shortage.

[0004] Rainwater and snowwater are lightly polluted waters that can be used as landscape water, greening water or domestic water after simple treatment. When traditional water resource development methods cannot increase water sources, the resource utilization of rainwater and snowwater has become an economical and practical way of water resource development.

[0005] In recent years, calls for environmental protection and energy conservation have become increasingly prominent, leading to a growing emphasis on the recycling of rainwater and snowwater. The collection and utilization of rainwater and snowwater plays a vital role in conserving water and soil and improving the ecological environment. Sometimes, during the year, we need to manage floods and drainage for a period of time, while at other times, we face water shortages. Therefore, the utilization of rainwater and snowwater must achieve both flood control and water conservation. Summary of the Invention

[0006] The purpose of the present invention is to provide a highway water storage reservoir. On the basis of setting up a side ditch, a culvert capable of receiving water from the slope is set below the side ditch. The culvert can store water and supply water to the water facilities along the highway to save water resources, and can also meet the needs of flood control and drainage of the highway to ensure the safe use of the highway.

[0007] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a highway water reservoir, including side ditches arranged on both sides of the highway slope, a culvert is buried under the side ditch, a water inlet pipe and a water intake are arranged on the top of the culvert, the water inlet pipe extends upward into the side ditch, and a plurality of water inlet holes are densely distributed on the wall of the water inlet pipe; in the side ditch, a filtering area is arranged around the water inlet pipe, and a sedimentation area is laid upstream of the filtering area; the water intake is connected to the water use facility through a buried pipeline.

[0008] As an embodiment, the culvert is a longitudinal culvert or a transverse culvert. The longitudinal culvert is laid along the direction of the side ditch, and multiple water inlet pipes and water intakes are arranged at intervals along the direction of the longitudinal culvert; the extension direction of the transverse culvert and the direction of the side ditch form an acute angle or a right angle, and the transverse culverts are laid in multiple rows at intervals along the direction of the side ditch, and the multiple rows of transverse culverts are connected by end connecting vessels.

[0009] As another embodiment, the culvert is a longitudinal culvert laid along the direction of the side ditch, and a plurality of three-way inspection wells are arranged on the longitudinal culvert along its direction at intervals. The longitudinal culvert is connected to the transverse culvert through the three-way inspection wells. The angle between the extension direction of the transverse culvert and the direction of the longitudinal culvert is an acute angle or a right angle. Each row of transverse culverts is connected by an end connecting vessel, and at least one water intake is provided on the transverse culvert.

[0010] The pipe culvert is formed by connecting multiple corrugated pipes through flanges.

[0011] The water use facilities include one or more of a highway water supply device installed under the outer guardrail of the highway, a slope sprinkler device installed on the slope of the highway, a rainwater recycling system installed in the service area or parking area, and a farmland irrigation system installed in the farmland along the highway.

[0012] The sedimentation area is paved with sand.

[0013] The filter area is formed by mixing sand and gravel of different sizes.

[0014] The lower end of the water inlet pipe is provided with a purification and filtering device.

[0015] When the culvert is a longitudinal culvert laid along the ditch, the longitudinal culvert is interrupted at the bridge and tunnel position where the highway passes, and an end plate is provided at the interruption position, and an overflow outlet is provided on the upper part of the end plate.

[0016] The distance from the overflow outlet to the bottom of the end plate is 80% to 90% of the corresponding circumferential diameter of the end plate.

[0017] The beneficial effects of the present invention are as follows: the culverts of the present invention are arranged along the expressway, the longitudinal culverts are laid along the ditch on the side of the expressway, and the transverse culverts are arranged in multiple rows at intervals along the ditch. Therefore, no matter what type of culvert is used, it can have a large storage capacity, store enough rain and snow water, and reduce evaporation. On the one hand, it can meet the water demand along the line and save water resources. On the other hand, it can play a role in flood control and drainage, flood retention and flood storage when the precipitation is heavy, thereby ensuring the safe use of the expressway.

[0018] After adopting the present invention, a highway water supply device can be installed outside the guardrail on the outside of the highway to pump water from the culvert for use by sprinkler trucks and cleaning vehicles for highway maintenance; the slope sprinkler device installed on the slope can also use the water in the culvert to irrigate the vegetation on the slope, reducing the cost of vegetation maintenance; the service area or parking area of ​​the highway can also use the water in the culvert as its permanent water source, thereby reducing the construction of water collection facilities in the service area and parking area, saving construction investment.

[0019] The separately arranged transverse pipe culverts and the transverse pipe culverts arranged on the longitudinal pipe culverts of the present invention can also replace the current evaporation ponds, avoiding the requisition of land for the construction of evaporation ponds. Moreover, the transverse pipe culverts are all buried underground, and the ground can still be used as arable land, saving land resources. The ends of the transverse pipe culverts are connected with end connectors, so that the present invention can be used as a permanent water source for farmland irrigation, providing irrigation water to the ground farmland irrigation system, and reducing the investment in water diversion facilities for farmland.

[0020] The present invention adopts a filtering method that combines a sedimentation area and a filtration area, which can effectively intercept impurities such as mud, leaves, plastic bags, etc. in the water, and prevent large impurities from entering the culvert and causing blockage of the pipeline. The filtration area is arranged around the protruding water inlet pipe to further improve the interception and filtration effect; the purification filter provided can further purify the water to reduce the water purification pressure in the service area.

[0021] The pipe culvert of the present invention is formed by butting and fixing multiple sections of corrugated pipes with equal cross-sectional areas, which can overcome the influence of thermal expansion and contraction on the pipeline. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present invention will be further described in detail below with reference to the accompanying drawings and examples, but they are not intended to limit the invention in any way.

[0031] A highway water reservoir is set up on both sides of the highway to collect rainwater, snowwater and drainage from the highway pavement 1. The collected water can be filtered and processed. The collected water is provided as a water source for various water facilities through water intakes. In the rainy season or in areas with heavy rainfall, the reservoir also has the regulating function of storing and discharging flood water, thereby ensuring the safe use of the highway.

[0032] Example 1: Figure 1-3 As shown, the highway water reservoir described in the present invention includes side ditches 5 arranged on both sides of the highway slope 4, and longitudinal culverts 6 buried below the side ditches 5 along the direction of the slope 4. Since the side ditches 5 are arranged along the direction of the highway, the direction of the longitudinal culverts 6 is consistent with that of the highway.

[0033] The cross section of the side ditch 5 is a trapezoid with a small bottom and a large mouth. The longitudinal culvert 6 is composed of multiple steel corrugated pipes of equal cross-section connected by flange assembly. The cross-sectional area and storage capacity of the longitudinal culvert 6 can be designed in a targeted manner according to the local annual precipitation. A plurality of water inlet pipes 8 and a plurality of water intakes 12 are arranged at intervals along the top of the longitudinal culvert 6. The water inlet pipes 8 are square pipes so as to be connected to the corrugated pipes. The water inlet pipes 8 extend upward into the side ditch 5. The wall of the water inlet pipes 8 is densely covered with multiple water inlet holes. A filtration area 9 is laid around the water inlet pipe 8 in the side ditch 5, and a sedimentation area 10 is laid upstream of the filtration area 9. The water intakes 12 are arranged at a certain distance, such as 500 meters apart. The water intakes 12 are connected to the water facilities along the highway through pipelines.

[0034] The filtration area 9 is composed of a mixture of pebbles of varying sizes, stacked around the inlet pipe 8 to a height greater than that of the pipe. The settling area 10 is paved with sand. After entering the gutter 5, water first passes through the settling area 10 and then through the filtration area 9. Most impurities in the water are trapped in the gutter 5 before flowing through the inlet holes in the wall of the inlet pipe 8 and into the longitudinal culvert 6 below.

[0035] A purification filter 11 is also installed at the lower end of the water inlet pipe 8 to filter and purify the water entering the longitudinal culvert 6. The purification filter 11 can be a commercially available conventional water treatment filter.

[0036] The water facilities along the expressway include but are not limited to the expressway water supply device 3, the slope sprinkler device 7 and the rainwater recycling system set up in the service area or parking area.

[0037] The highway water supply device 3 is installed on the shoulder of the highway pavement 1, outside the outer guardrail 2. It includes a pumping device. The water inlet of the pumping device is connected to the water intake 12 on the longitudinal culvert 6 via a pipe buried along the side slope 4. The pipe is inserted through the water intake 12 below the water surface of the longitudinal culvert 6. The water outlet of the pumping device is equipped with a connector to connect with the water tanks of water-using vehicles such as sprinklers and cleaning vehicles used for highway maintenance, providing water for vehicle operations. As a result, maintenance vehicles no longer need to frequently enter service areas to collect water, improving vehicle operating efficiency, saving water resources in service areas, and promoting water recycling.

[0038] Slope sprinkler irrigation system 7 is connected to a longitudinal culvert 6 via a water supply pipe embedded within slope 4. The water supply pipe extends below the water surface through a water intake on longitudinal culvert 6, providing irrigation water to slope sprinkler irrigation system 7. Slope sprinkler irrigation system 7 utilizes the water stored in longitudinal culvert 6 to irrigate the vegetation on slope 4. This facilitates water recycling, reduces vegetation maintenance costs, and prevents slope landslides caused by excessive water use by sprinkler trucks. Sprinkler trucks can also be used to irrigate vegetation in the central median of the highway, similarly conserving water resources.

[0039] The rainwater recycling system is set up in the service area or parking area of ​​the expressway and is connected to the water intake of the longitudinal culvert through a pipe. In this way, the water in the longitudinal culvert can be used as a permanent water source for the service area or parking area. The water in the longitudinal culvert can be used for toilet water, car washing water, sanitary water in the service area, etc. If further purified, it can also be used as drinking water, which greatly improves the recycling of water resources and can save the construction of a water collection pool in the service area, further saving costs.

[0040] At the bridge and tunnel locations where highways pass, it's not possible to install side ditches and longitudinal culverts 6. Therefore, the longitudinal culvert 6 is interrupted at this location, sealed with an end plate 13. An overflow port 14 is located above the end plate 13. Typically, the distance from the overflow port 14 to the bottom of the end plate 13 is 80% of the corresponding circumference diameter of the end plate 13. This ensures that the water within the longitudinal culvert 6 meets the needs of various water-using facilities. When drainage is necessary, excess water is directly discharged through the overflow port 14. If the amount of water to be drained is large, the end plate 13 can be removed to increase drainage speed and achieve the desired flood discharge.

[0041] When the expressway passes through a river-crossing bridge, a gate can be installed at the end of the longitudinal culvert 6 to open the gate during floods, so that the longitudinal drainage of the expressway is unobstructed.

[0042] Example 2: The difference between this example and example 1 is that: Figure 4 As shown, on the basis of setting up the longitudinal culvert 6 as described in Example 1, a three-way vertical inspection well 15 is set on the longitudinal culvert 6 at a certain interval along its direction. Each three-way vertical inspection well 15 is connected to a transverse culvert 16. The corrugated pipe used in the transverse culvert 16 has the same specifications as the corrugated pipe used in the longitudinal culvert 6. The transverse culvert 16 extends to the bottom of the farmland outside the side ditch, and an acute angle or a right angle is formed between the extension direction of the transverse culvert 16 and the direction of the longitudinal culvert 6. Different from the setting method of the longitudinal culvert 6, there is no need to set a side ditch above the transverse culvert 16, and there is no need to set a water inlet pipe on the transverse culvert 16. Instead, water is fed in through the three-way vertical inspection well 15. It is only necessary to set a water intake at the top of the transverse culvert 16. At least one water intake is set. When multiple water intakes are set, multiple water intakes are arranged at intervals. As shown Figure 7 As shown, the transverse culverts 16 are connected by end connectors 17. The end connectors 17 are connecting pipes with multiple joints, each of which is connected to a transverse culvert 16. The transverse culverts 16 are buried under the farmland and can be buried at a greater depth so as not to affect the cultivation of crops or the management of vegetation on the ground. A farmland irrigation system is set up near the transverse culverts 16, and the farmland irrigation system draws water from the water intake of the transverse culverts 16 through pipes for irrigation. The use of transverse culverts 16 not only replaces the original evaporation ponds, eliminating the need to requisition land for the construction of evaporation ponds and thus saving land resources, but also allows the water from the transverse culverts 16 to be used to irrigate crops or vegetation on the ground, making the present invention a permanent water source for farmland irrigation.

[0043] Other structures not described in detail are the same as those in Example 1.

[0044] Example 3: The difference between this example and example 2 is that: Figure 5 、 6As shown, this embodiment does not provide a longitudinal culvert 6, but provides multiple rows of transverse culverts 16. Each row of transverse culverts 16 is also formed by connecting multiple corrugated pipes. The extension direction of each row of transverse culverts 16 forms an acute angle or a right angle with the direction of the side ditch 5. The water inlet end of the transverse culvert 16 is located below the side ditch 5. The water inlet end is provided with an inlet pipe 8, which extends upward into the side ditch. The water entering the side ditch 5 passes through the sedimentation area 10 and the filtration area 9 and then enters the transverse culvert 16 through the inlet pipe 8. The rest of the top of the transverse culvert 16 is provided with water intakes at intervals along its extension direction, or only one water intake is provided. Figure 7 As shown, the transverse culverts 16 are connected by end connectors 17. The end connectors 17 are connecting pipes with multiple joints, each of which is connected to a transverse culvert 16. The transverse culverts 16 extend below the farmland outside the side ditch and can be buried at a greater depth so as not to affect the cultivation of crops or the management of vegetation on the ground. A farmland irrigation system is set up near the transverse culverts 16, and the farmland irrigation system draws water from the water intake of the transverse culverts 16 through pipes for irrigation. The use of transverse culverts 16 not only replaces the original evaporation ponds, eliminating the need to requisition land for the construction of evaporation ponds and thus saving land resources, but also allows the water from the transverse culverts 16 to be used to irrigate crops or vegetation on the ground, making the present invention a permanent water source for farmland irrigation.

[0045] In this embodiment, a highway water supplier, slope sprinkler device or service area water purification station as described in Example 1 can also be set up, and necessary water facilities can also be set up as needed.

[0046] In the actual process of highway construction, various culverts on both sides of the highway can be connected through pipelines to expand the storage capacity available on one side, and the side with high water consumption can use the storage capacity on the opposite side.

[0047] Example 4: The present invention will be further described below with reference to specific examples.

[0048] Taking the longitudinal culvert as an example, the longitudinal culvert uses a steel corrugated pipe with a diameter of 3m. The length, width and height of the water inlet pipe are 100cm, 50cm and 70cm respectively. The length of the water inlet pipe exposed above the side ditch is not less than 30cm. The storage capacity of the reservoir corresponding to the longitudinal culvert of this diameter (excluding the water storage capacity of the side ditch) is 14130m per kilometer. 3 According to this design standard, the scale of the reservoir described in the present invention is divided into the following categories:

[0049] 1. Small (2) reservoir: The storage capacity of a 10 km highway reservoir is 141,300 m 3 , reaching the standard of my country's small (2) type reservoir (see the classification and design standards of water conservancy and hydropower hub projects), protecting 50,000 mu of farmland, controlling flooding in 30,000 mu of area, and irrigating 5,000 mu of area.

[0050] 2. Small (1) reservoir

[0051] The storage capacity of the reservoir for 100 km of expressway is 1,413,000 m 3 , reaching the standard of my country's small (1) type reservoir (see the classification and design standards of water conservancy and hydropower projects), protecting 50,000 to 300,000 mu of farmland, controlling waterlogging area of ​​30,000 to 150,000 mu, and irrigating area of ​​5,000 to 50,000 mu.

[0052] The highway reservoirs described in this invention store water during the rainy season and snow in the winter. During droughts, water is automatically drawn from a central belt sprinkler system or a side slope sprinkler system for watering plants and flowers, or drawn from water intakes by sprinkler trucks. The reservoirs on both sides of the highway serve as permanent water sources for service areas. Once delivered to the service areas, the water is purified to meet acceptable usage standards, such as for car washes, fountains, and watering service area plants and flowers. In particularly needed service areas, water can also be purified to drinking water quality.

[0053] Highway reservoirs can serve as flood detention and storage in areas with abundant rainfall:

[0054] 1. Flood retention: Flood retention means temporarily keeping flood water in a reservoir.

[0055] 2. Flood storage: By using water before the flood season and lowering the reservoir water level to its lowest level, the reservoir can store floodwater during the flood season. The floodwater stored in the reservoir can be used for planned development during the dry season.

[0056] The above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the same. Those skilled in the art should understand that the specific implementation methods of the present invention can be modified or replaced with equivalents with reference to the above embodiments. Any modifications or equivalent replacements that do not depart from the spirit and scope of the present invention are within the scope of protection of the pending claims.
