Elbow-shaped water inlet runner formwork and mounting method thereof
The invention relates to an elbow-shaped water inlet runner formwork and a mounting method thereof, and relates to the technical field of hydraulic engineering construction. The elbow-shaped water inlet runner formwork comprises an inner cavity formwork, the inner cavity formwork comprises an inner core mold frame and a covering plate covering the periphery of the inner core mold frame, the inner core mold frame comprises two independent forming sections including an inlet shrinkage transition section and a bend outlet section, the inlet shrinkage transition section and the bend outlet section each comprise a plurality of rib rings designed according to an elbow-shaped runner, and the rib rings are spliced with one another. According to the elbow-shaped water inlet runner formwork, the effects that the formwork adapts to the whole transition process that an approximate rectangular inlet is connected with the transition shrinkage section, then connected with the bend transition circular runner and finally connected with a circular outlet of the elbow-shaped runner, the kinetic energy loss of water flow in the elbow-shaped runner is reduced on the basis that the complex flow state structure of bend water flow is met and the formwork mounting difficulty is reduced, and the unfavorable hydraulics influence of the bend water flow is effectively eliminated are achieved.
本申请涉及一种肘形进水流道模板及其安装方法，涉及水利工程施工的技术领域，其肘形进水流道模板包括内腔模板，所述内腔模板包括内芯模架和覆盖于内芯模架外围的覆盖板，所述内芯模架包括进口收缩渐变段和弯道出口段两个独立成型段，所述进口收缩渐变段和弯道出口段均包括多个按肘形流道设计而成的肋环，多个肋环相互拼接。本申请具有适配肘形流道由近似矩形进口连接渐变收缩段、再连接弯道渐变圆形流道、最后连接圆形出口的整个渐变过程，在满足弯道水流的复杂流态结构并降低模板安装难度的基础上，减少水流在肘形流道中的动能损失，有效消除弯道水流不利的水力学影响的效果。
