Description

 Method, facility and application of drainage irrigation

 The present invention relates to drainage irrigation methods, facilities, and applications, and more particularly, to a method, facility, and application for drainage irrigation on various roads, the tops of buildings, green spaces, and soil plantations or barren hillsides. Background technique

 Roads, drainage networks, and greening projects are important urban infrastructures. The operation of these facilities directly affects the quality of the urban environment. Curb-isolated masonry components of traditional roads are generally composed of curb-isolated stones and curb-level flat stones. Among them, curb-level flat stones are laid horizontally on both sides or one side of the road, and their upper surfaces are flush with the road surface. The isolation stone is laid vertically next to the curb flat stone on the outermost side of the road, and its upper surface is higher than the road surface. In order to facilitate the drainage of rainwater, a curb-isolated stone rainwater discharge opening will be set at a certain distance on the road (usually 30 to 50 meters), or rainwater drainage should be laid at the location where the curb-isolated stone rainwater discharge opening should be built. The special castor for the mouth is connected to the underground pipe laid underground.

 In order to improve the speed and efficiency of rainwater discharge, in the past, rainwater drains on roads should be set at the lowest position on the road. Therefore, if necessary, a longitudinal slope of the road will also be set, that is, the road has a certain inclination slope along the longitudinal direction of the road. A rainwater drain or a dedicated rainwater drainage device is set at the lowest position on the longitudinal slope of the road.

For example, in the document disclosed in Japanese Patent Publication No. 6-248610, as shown in FIG. 13, on both sides of the green belt in the middle of the lane surface with a certain slope, a row of curb spacers are respectively built, and each curb The barrier stones are uniformly inlaid with two permeable prefabricated blocks. When laying, the bottom of each permeable precast block should be flush with the driveway surface. When raining or road cleaning and flushing, the rainwater or flushing water on the lane surface can flow into the soil of the green isolation zone along the pores of the prefabricated block to irrigate the plants (as indicated by the arrow), and the mud and sand entrained in the water The object is separated between the curb and the road surface. It must be Regularly carrying out nursing work such as dredging and dredging will consume a lot of manpower and costs.

 Another example is the document disclosed in the German patent, DE 295 08 680 (1). As shown in FIG. 14, a row of curb spacers are laid on both sides of the sloped pavement road. Where drainage outlets are formed, the sloping green belts or planting areas are located on the outer side of the isolation stones at each edge of the curb. When raining or road cleaning and flushing, rainwater or flushing water can flow directly along the slope of the road through the drainage outlet of the curb stone into the green belt or planting area for irrigation. If the rain is heavy, it is easy to damage the plants and cause soil erosion and water waste.

 Another example is the French patent, No. 1.368.655-disclosed in the document, as shown in FIG. 15, a row of curb spacers preset with pouring pipe joints are laid on both sides of the road. The pipe joints are connected to the underground drainage pipe and buried together. The cross-section of the curb-isolation stone is L-shaped. When laying, the top surface of each curb-isolation stone is flush with the sidewalk surface, and its bottom end is inclined inward. The lower part of the preset pipe joint opening is flush with the inner edge of the inclined upper surface. When raining or road cleaning and flushing, rainwater or flushing water can be drained through the joint directly into the underground drainage pipe along the opening of the pipe joint, and the turbid flow of mixed water containing mud or other debris will cause pollution and siltation of the pipeline. Blocking must bring a lot of dredging work and costs, and also waste a lot of water resources.

 The above-mentioned conventional techniques have brought a lot of inconvenience to road cleaning and maintenance work. The pavement cleaning and dredging work has high costs, high labor intensity, and generates dust during operation. Incomplete cleaning will cause continuous pollution and other shortcomings. In addition, when raining or irrigating the green space and green belts on both sides of the road, it will cause soil erosion, pollute and block the underground drainage pipes of the road, and inevitably cause pollution to the downstream water bodies. Therefore, the existing roadside facilities will cause green space during rainfall. Or the debris from the green belt is flushed onto the pavement, and then flushed into underground pipes and rivers and lakes, which not only causes soil erosion, but also causes chain and continuous pollution problems. Summary of the Invention

 1. Environmental protection: The muddy water and clean water on the road can be discharged separately, and the muddy water flows into the green space. Muddy water contains a large amount of "organic matter", which can improve soil fertility and benefit plant growth. Pure rainwater flows into underground pipes. It reduces the siltation of pipelines, pollution of river water bodies, and complicated cleaning work.

 2. Improving drainage efficiency will not cause road area water, and unnecessary longitudinal slopes on the pavement will be avoided. Drainage troughs can be used instead of longitudinal slopes, which reduces costs.

 3. Improve the efficiency of pavement cleaning: Rinse with water is faster and more thorough than cleaning, thus avoiding dust pollution in the industry, and the water that flushes the pavement flows into the green space, not only for the pavement cleaning work, but also the water required for the green space Can also be supplemented.

 4. The utilization rate of natural resources has been improved. In the rainy season, as long as there is a source of water on the pavement, there will be a chance for water to accumulate in the green space. Natural rainfall is effectively used, and the remaining water can be collected and used.

 5. Eliminate soil and water loss: Because the pavement is higher than the planting area, the chain pollution and continuous pollution caused by miscellaneous materials to the pavement are avoided, and a reasonable water level is set for the terraced fields on the barren hillsides. The remaining water is discharged through the ditch pipes, which is fundamentally Disasters caused by soil erosion, landslides, debris flows, etc. are avoided.
