机带井实质是一种小口径土井。从水力特性上讲,它是井底和井壁都能进水的潜水非完整井。因井深度与离心泵的理论吸程相接近,水泵进水管也可作井管,加上井口径小,又便于把进水管与大气隔绝,起到与塑管真空井同样增大水泵吸程的作用,所以农民非常喜欢这种井型。它是沙颍河流域特定的供水段与水泵驱动力接近的一种巧合,当前是手压饮水井普遍分布的沙颍河中下游的特殊产物。今年入夏以来,沙颍河流域降雨量普遍稀少。据气象部门统计,7月份降雨量为27.8毫米,仅是常年的14.8％,干旱直接威胁着今年的农业生产。目前农业实行科学套种,提高了复种指数,增大了用水量。按原来农田水利建设的井灌工程无法满足群众抗旱用水的要求。经过多年抗旱,农民大部分已购置动力机、喷灌泵和输水带等灌溉用具,在沙颍河流域出现了自费争打机带井的热潮,在果园、瓜菜地基本实现了一块地一眼井。
Machine belt wells is a kind of small-diameter soil well. In terms of hydraulic characteristics, it is a submersible incomplete well that can feed water to both the bottom of the well and the wellbore. Because of the well depth and the theoretical suction close to the centrifugal pump, pump inlet pipe can also be used for well pipe, together with the well diameter, but also easy to isolate the inlet pipe and the atmosphere, play the same with the plastic pipe vacuum pump to increase the pump suction Role, so farmers like this well type. It is a coincidence that the specific water supply section of the Shaying River Basin is close to the driving force of the pump. Currently, it is a special product of the middle and lower reaches of the Shaying River that is widely distributed in hand pressure drinking water wells. Since the beginning of summer this year, the rainfall in the Shaying River Basin is generally scarce. According to the statistics of the meteorological department, the rainfall in July was 27.8 millimeters, only 14.8% of the normal year. Drought directly threatened this year’s agricultural production. At present, agriculture implements scientific intercropping, raising the multiple cropping index and increasing water consumption. According to the original farmland water conservancy construction well irrigation project can not meet the requirements of drought water. After years of drought-fighting, most farmers have purchased irrigation equipment such as power machines, sprinkler pumps and water conveyance belts, and there has been a boom in the Shaying River basin at their own expense and contention zone. In the orchards and melons, basically a single well .
