栏栅式取水工程的取水量由栏栅的宽度、栅条长度、栏栅的设置角度、栅隙、栅

栏栅式取水工程的取水量由栏栅的宽度、栅条长度、栏栅的设置角度、栅隙、栅条形状等很多因素决定。本文探讨了在有足够大的集水廊道的前提下，栅条长度、栏栅的设置角度、栅隙对取水量的影响程度。结果表明，栏栅式取水工程的取水量主要决定于栏栅的设置角度，栅条长度和栅隙对取水量的影响程度较小。虽然，栏栅的设置角度越小取水量越大，但是由于在自然状态下山区河水中的粗沙、砾石以及落叶等漂浮物会引起栏栅堵塞，栏栅的设置角度越小堵塞越严重，而栏栅的设置角度过大取水量会大幅度减少。从试验结果得知，栏栅的设置角度不宜大于50°，合适的栏栅设置角度应因地制宜，根据河流径流泥沙含量、泥沙的粒径构成及水流中漂浮物的多少进行确定。而栅条长度和栅隙的确定需要从河流径流的含沙量、泥沙的粒径构成、设计取水量和栅条强度等多方面进行综合考虑。

Grating Intake Project quantity of water is determined by the width of the fence, trash rack length, the setting angle of fencing, gate gap, rack shape many factors. This paper examines the quantity of water large enough catchment corridor premise, trash rack length, the setting angle of fencing, gate gap impact. The results show that the grating Intake Project quantity of water is mainly determined by the setting angle in the fence, trash rack length and gate gap to a lesser extent the impact of water withdrawals. Although the setting angle of the fence is the smaller the greater the quantity of water, but because of coarse sand, gravel and fallen leaves floating debris in the mountain river in its natural state will cause the fence to plugThe pickets set the angle of the smaller clogging the more serious, while fencing set the angle is too large quantity of water will be greatly reduced. Learned from the test results, the pickets set the angle should not be greater than 50 °, suitable fencing set the angle should be adapted to local conditions, sediment particle size composition and flow of floating debris in river runoff and sediment content, the amount of determination. Trash rack length and gate gap determined from river runoff sediment concentration, sediment particle size, and design aspects of the comprehensive consideration of the quantity of water and trash rack strength.

Fence type water intake project of water consumption by fences, fence gate width, length setting angle, gate gap, grid shape and many other factors.This paper discusses the have enough gallery under the premise, grid length, fences, gate gap setting angle of water influence.The results show that, fence type water intake project of water consumption is mainly determined by the set angle bars, grid length and grid gap on water less effects.Though barriers, setting angle is small quantity of water is greater, but because in a natural state in mountain areas in river water by coarse sand, gravel and leaves float causes fences blocking,The fence set angle smaller jams more and more serious, and the fence set angle is too large to quantity of water will be greatly reduced.From the experimental results, the fence set angle should not be greater than 50 °, suitable fence set angle should suit one's measures to local conditions, according to the river runoff sediment concentration, sediment particle size composition and water floats were determined how much.And grid length and grid gap can be determined from the river sediment concentration in runoff, sediment particle size composition, design content and grid strength and many other aspects were considered.

Water intake engineering of water intake by fencing-fence the width, bar length, set the angle of the fence, gate gap, many factors, including grid shapes decisions. This article discusses water where there is a large enough set of corridors under the premise of, bar length, set the angle of the fence, blade gap on influence of water level. Results show that the fence-water intake engineering of water intake main decided to set the angle of the fence, bar length and grid slots less impact on water. Although, set the angle of the fence as little water as possible, but due to the natural state of rivers in mountainous areas under coarse, gravel and leaves and other floating debris in fences caused by congestion,Smaller set angle fence blocking the more serious, and set the angle of the fence can be much too much water intake reduction. From the test results that, set the angle of the fence should not be greater than 50 °, suitable fences set point should be adapted, according to river runoff sediment concentration, sediment particle size composition and determines the number of floats in the water. Bar length and grid slots identified from river runoff sediment concentration, sediment particle size composition, design of water intake and grid integration of strength, and many other considerations.
