Embodiment Construction

[0015] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] Such as figure 1 The non-powered irrigation and drainage system of the coastal landscape includes drainage wells set up on the bank and extending to Hanoi along the bank slope. The bottom of the intake and drainage well is provided with a percolation device 1 below the water surface, and a water intake filter device 5 is provided in the percolation device 1. After the installation is completed, the well cover can be set, and fences and warning signs can be set up around. A water delivery pipe 2 is vertically arranged in the water intake and drainage well, the water delivery pipe 2 is made of PVC material, the diameter is 5-10cm, and the buried depth is preferably 15-20cm; the bottom end of the water delivery pipe 2 is connected to the water outlet of the percolation device 1 A plurality of irrigation and drainage pipes...

Abstract

A system for irrigating and draining coastal landscape without power includes a water intake and drainage well located on the shore and extending along the slope into the river, a percolation device is arranged at a position lower than the water surface at the bottom of the water intake and drainage well, a longitudinal water delivery pipe is arranged in that water taking and draining well, the bottom end of the water delivery pipe is connected with the water outlet of the infiltration device, a plurality of irrigation and drainage pipes are horizontally arranged at the position of the crop root on the shore, the irrigation and drainage pipes are communicated with the water delivery pipe, and a plurality of water-permeable and air-impermeable micro-pore irrigation and drainage devices arearranged on the irrigation and drainage pipes at intervals. The device has both irrigation function and drainage function, without additional power, and can automatically make up water and drain waterfor crops at different heights of bank slope, so that the soil root layer around the emitter is kept in a constant water range, energy is saved, pollution is reduced, water resource utilization efficiency is improved, and the leaching risk of soil particles and nutrients is reduced.

Description

technical field [0001] The invention relates to the field of agricultural irrigation and drainage, in particular to a non-powered irrigation and drainage system for coastal landscapes. Background technique [0002] With the development of urban civilization and the improvement of people's living standards, riverside ecology and landscape construction has become an important part of municipal construction. The construction of coastal artificial landscape requires irrigation and drainage to maintain the normal growth of plants. Conventional irrigation systems require power to lift water to achieve irrigation. Surface drainage will lead to hydraulic erosion of bank slopes and cause water pollution. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies of the background technology, the present invention discloses a non-powered irrigation and drainage of the coastal landscape by utilizing the principle of soil water potential and the...
