跌水与急流槽宜用浆砌圬工结构;跌水的台阶高度应按设计或根据地形、地质等条件确定;多级台阶的各级高度可以不同,其高度与长度之比应与原地面坡度相适应,台阶高度应不大于 0.6m,不同台阶坡面应上下对齐。
1) The drop and chute should be made of mortar masonry structure; the step height of water drop should be determined according to the design or terrain, geology and other conditions; the height of multi-stage steps can be different, the ratio of height to length should be adapted to the original ground slope, the height of step should not be greater than 0.6m, and the slope surface of different terrace should be aligned up and down.
2)跌水可用浆砌片石或水泥混凝土浇筑。沟槽、壁及消力池的边墙厚度:浆砌片石为 0.25~0.4m,混凝土为 0.2m,高度应高出计算水位至少 0.2m,槽底厚度为 0.25~0.4m,出口应设置隔水墙。
2) Water drop can be poured with mortar rubble or cement concrete. The thickness of side wall of trench, wall and stilling basin: mortar rubble is 0.25 ~ 0.4 m, concrete is 0.2 m, the height should be at least 0.2 M higher than the calculated water level, the thickness of groove bottom is 0.25 ~ 0.4 m, and the outlet should be set with water barrier.
3)跌水应按设计要求设施工消力槛。
3) The construction stilling sill shall be set according to the design requirements.
4)跌水槽一般筑成矩形,但跌水高度不宜过大,槽底纵坡应较缓,也可采用梯形断面。梯形跌水槽身应在台阶前 0.5~1.0m 和台阶后 1.盖土网 防寒布 麻绳 油麻绳 麻刀 沥青麻绳 静压造型线 自动浇注机 铸铁拍门 钢制拍门 玻璃钢拍门0~1.5m 范围内加固。
4) The drop trough is generally built into a rectangle, but the height of the drop should not be too large, and the longitudinal slope at the bottom of the trough should be gentle, and the trapezoidal section can also be used. The trapezoidal chute body should be reinforced in the range of 0.5 ~ 1.0m in front of the steps and 1.0 ~ 1.5m behind the steps.
5)急流槽的纵坡,一般不宜超过 1:1.5,可用浆砌片(块)石砌筑或混凝土浇筑。
5) Generally, the longitudinal slope of the chute should not exceed 1:1.5, which can be built with mortar rubble or concrete.
