Single-wing type double-layer net rack concealed pipe device for farmland unsaturated soil drainage
The invention relates to the technical field of agricultural water and soil engineering, and particularly relates to a single-wing type double-layer net rack concealed pipe device for farmland unsaturated soil drainage. The single-wing type double-layer net rack concealed pipe device comprises an impermeable wing part, a permeable net rack and an isolation layer, wherein the impermeable wing partis of a flat plate structure; the permeable net rack is a spliced net rack composed of an upper layer, a middle layer and a lower layer, and the permeable net rack comprises an upper-layer common netrack, a lower-layer common net rack and a middle-layer sawtooth net rack; the end of the permeable net rack is horizontally and fixedly connected with the impermeable wing part; the isolation layer islaid on the outer side face of the permeable net rack; and the other end of the permeable net rack is bent and rewound into a barrel shape and fixedly connected with the inner side face of the connecting portion through an adhesive layer. According to the single-wing type double-layer net rack concealed pipe device, the phenomenon that water flow flows around a drainage concealed pipe can be effectively relieved, secondary leakage generated at the bottom of the concealed pipe after the water flow enters the concealed pipe is avoided, the shape of the section of the pipe can be kept unchanged,the work efficiency is effectively improved, and the single-wing type double-layer net rack concealed pipe device is reasonable in structure, economical and practical.
本发明涉及农业水土工程技术领域，是一种用于农田非饱和土壤排水的单翼型双层网架暗管装置，包括不透水翼部、透水网架、隔离层；不透水翼部的结构为一平板；所述透水网架的结构为上、中、下三层的拼装网架，包含上、下两层的普通网架、中间层的锯齿网架，所述透水网架的端部与不透水翼部水平固定连接，透水网架的外侧面铺设有隔离层，所述透水网架的另一端弯曲回绕成筒状，利用粘胶层与连接部位的内侧面固定连接。本发明可有效地减缓水流沿排水暗管周围绕流的现象，避免水流进入暗管后在暗管底部产生二次渗漏，还能够保持管道断面形状不变形，有效提高工作效率，结构合理、经济实用。
