公路雨水口篦子泄水量试验研究

Study on Test of Sluice Capacity of Double-Edged Fine-Toothed Comb at Rainfall Inlet at Highway

雨水口篦子泄水量是雨水口泄水能力好坏的关键因素 ,本文通过水工模型试验对不同型式的篦子在不同上游来水流量以及不同纵坡条件下的泄水量做了系统的试验研究 ,最后对雨水口篦子型式的选择提出了推荐方案 ,并对篦子的安装和维护提出了应注意的事项。

The sluice capacity of double-edged fine-toothed comb at rainfall inlet is a key factor whether the sluice capacity at rainfall inlet is well or not. The paper makes the systematic test and study on the different types of double-edged fine-toothed comb in the flow from different upper reaches and the sluice capacity under different longitudinal slope condition by the hydraulic model test. At last, the paper puts forward the recommended option for the selected type of double-edged fine-toothed comb and puts forward the matters for attention in the installation and maintenance of double-edged fine-toothed comb.
