【摘要】：针对船闸下游引航道口门区横向流速超标问题,分析多种导流建筑物削弱口门区回流的机理,提出运用排桩调整水流流态的技术,并将排桩的概念进行延拓,涵盖以往多种导流建筑形式。结合物理模型试验,将排桩技术运用于大藤峡枢纽船闸下游引航道口门区水流条件改善中。成果表明:采用L湓D为1.0的排桩整流能降低口门区回流流速。
[Abstract]:Aiming at the problem of the transverse velocity exceeding the standard in the entrance area of the downstream approach channel of the shiplock, this paper analyzes on the mechanism of various diversion buildings weakening the backflow in the orifice area, puts forward the technology of adjusting the water flow state by using the drain pile, and extends the concept of the discharge pile. Covers a variety of previous forms of diversion construction. Combined with the physical model test, the piling technique is applied to the improvement of the flow conditions in the entrance area of the downstream approach channel of the Dadengxia Project Lock. The results show that the reflux velocity in the orifice region can be reduced by using the column rectifier with L gushing D = 1.0.
