Hilly and mountain area runoff accumulation system with ditches, tubes and kilns and accumulation method

Abstract

The invention discloses a hilly and mountain area runoff accumulation system with ditches, tubes and kilns. The system comprises a drainage ditch (2) and an invisible water sucking tube (3), wherein the invisible water sucking tube (3) is arranged at the bottom of the drainage ditch (2); a plurality of accumulation devices are mounted at intervals on the invisible water sucking tube (3); the accumulation devices comprise rain collection kilns (5), water collection and conveying tubes (4) and overflowing water conveying tubes (6); holes are formed in the walls of the rain collection kilns (5);the upstream of the invisible water sucking tube (3) is connected with the walls of the rain collection kilns (5) through the water collection and conveying tubes (4); and the downstream of the invisible water sucking tube (3) is connected with the holes in the walls of the rain collection kilns (5) through the overflowing water conveying tubes (6). By adopting the system, upper and lower rain collection kilns (5) on a slope are connected through the invisible water sucking tube (3) along a road, rainwater is accumulated layer by layer, after the rain collection kilns are all full of water, the excessive water can be discharged into a ditch at the lowermost part or other accumulation facilities, then efficient accumulation of runoff rainwater is achieved, and the problems of insect prevention and treatment, water conservation and drought resist irrigation in agricultural production in hilly and mountain areas in shortage of water resources are solved.

Description

technical field [0001] The invention belongs to the technical field of agricultural rainwater collection and storage facilities and land improvement engineering, and in particular relates to a hilly and mountainous runoff collection and storage system and storage method combined with trenches, pipes and cellars. Background technique [0002] In areas where groundwater development is limited or water is poor, it is of great significance to fully collect and utilize rainfall runoff resources. Especially in hilly and mountainous farmland, due to the steep slope, runoff is likely to occur, and runoff along the field side ditches and roadside ditches will also cause soil loss. The traditional rain cellar system uses the roadside drainage ditch to guide and store the flow, and installs a trash rack in front of the rain cellar entrance for primary filtration, and then enters the water cellar for storage and utilization. This method is difficult to remove mud due to the trash rack ...

Problems solved by technology

The traditional rain cellar system uses the roadside drainage ditch to guide and store the flow, and installs a trash rack in front of the rain cellar entrance for primary filtration, and then enters the water cellar for storage and utilization. This method is difficult to remove mud due to the trash rack Impurities such as sand will quickly lead to siltation in the rain cellar, and it must be dredged frequently, otherwise it will be difficult to play the role of water storage; some people also design to install a collecting pipe between the slope soil and the bedrock, and then enter the storage tank through the diversion pipe, but This method will also accelerate the loss of soil water in the field during irrigation and rainfall, which is not conducive to soil water retention. At the same time, it cannot effectively use the surface runoff of the drainage ditch, resulting in the loss of surface runoff resources; Rain cellars have different amounts of rainfall and storage speeds. If there is no connection between the rain cellars, they will not be able to regulate and may cause waste of rainwater resources.
