【摘要】：为了满足灌溉水温、供水水质以及水库下游水生态发展的要求,目前一些大中型水利工程中逐步要求采取分层取水措施。通过对常用分层取水口结构优缺点的比较,设计了一种新型的分层取水口结构,具有结构简洁、控制设备简单、操作简便、工程造价低等特点。该新型分层取水结构以叠梁门分层取水口水工结构为基础进行体型优化,结合浮式取水口和机控斜卧式闸门控制设备特点创新设计出新型闸门——以半圆形连体闸门和串联闸门作为控制设备。经模型试验验证了应用该新型取水口的可行性,并在重庆玉滩水库重建工程中得以实际应用,取得了良好的经济和社会效益。目前,该新型分层取水结构能够在中型水利工程中的任意水位条件下取表温层水,下一步需要重点研究该取水结构在大型水利工程中的合理利用。
[Abstract]:In order to meet the requirements of irrigation water temperature, water quality and the development of water ecology in the lower reaches of the reservoir, stratified water intake measures are gradually required in some large and medium-sized water conservancy projects. A new type of layered water intake structure is designed by comparing the advantages and disadvantages of the structure of the commonly used stratified water intake. It has simple structure, simple control equipment and operation. The new stratified water intake structure is based on the layered water intake structure of the laminated beam gate to optimize the body shape. The new type gate is designed with the characteristics of the floating intake port and the machine controlled horizontal sluice gate control equipment. The semi-circular connecting gate and the series gate are used as the control equipment. The model test is tested by the model test. The feasibility of applying the new type of water intake is proved, and it has been applied in Chongqing Yu Tan reservoir reconstruction project. It has achieved good economic and social benefits. At present, the new layered water intake structure can take the surface temperature layer water under the condition of any water level in the medium water conservancy project. The next step is to study the water intake structure in large water. The rational use of the benefit project.
