A side bay structure for reducing the sediment content of a river's pumping and irrigating water includes a side bay for pumping and irrigating, a side bay for lifting and irrigating water, a side bay wall for lifting and irrigating water, a side bay mouth connected with a river on one side of the river's flow, a side bay mouth for lifting and irrigating water, and a side bay mouth for lifting and irrigating water. Side bay wall butt bay mouth wall. The other end of the wall of the bay mouth extends towards the river side and forms an angle between the section of the bay mouth. The pumping pool is located farthest from the mouth of the side bay, and the bottom of the side Bay is provided with a slope inclining toward the river. Its structure is simple and easy to implement. When the river flows through the mouth of the side bay, it flows from the mouth of the side bay into the side bay. After deceleration, a large amount of sediment will sink to the bottom of the side Bay due to gravity. Sediment deposited at the bottom of the side Bay will be carried out by outward reflux. The sediment content in the pump pool will be greatly reduced. Thus, the wear and tear of lifting and irrigating equipment, especially water pumps, is reduced, and the sediment is transported to reservoirs and farmland downstream.
【技术实现步骤摘要】
减少河流提灌水含沙量的侧湾结构
本专利技术涉及一种河流提灌及渠道提灌泥沙过滤装置,特别适用于泥沙量较大的河水提灌工程,具体地说是一种减少河流提灌水含沙量的侧湾结构。
技术介绍
我国仅黄河上的提灌站就有10多个,年提水量数十亿方,黄灌区面积达数千万亩,仅景电高扬程提灌工程年提水量4亿多方,灌溉面积就达上百万亩。由于河水泥沙含量高,如黄河在景泰断面的平均泥沙含量每立方米为5.09kg。河流泥沙含量高,一方面对提灌设备,尤其是对泵的磨损严重;另一方面,显著加大了提灌成本,同时也给下游水库、农田输送了大量泥沙。然而,到目前为止,国内、外尚没有用于河流提灌的泥沙过滤技术和装置,而只是部分采用栅栏阻挡被淹的牲畜、柴草和其他体积较大的垃圾。
技术实现思路
本专利技术的目的在于提供一种结构简单、实施容易、实施效果好的减少河流提灌水含沙量的侧湾结构。为了实现上述目的。本专利技术采取如下技术方案:一种减少河流提灌水含沙量的侧湾结构,包括提灌泵池;其特征在于:在河岸的一侧设置有提灌侧湾,提灌侧湾设有侧湾围墙,提灌侧湾河流流经的一面设有与河流连通的侧湾湾口,提灌泵池置于提灌侧湾内,侧湾湾口的 ...
