水电站水轮机的尾水管是电站水工建筑物的基础工程,按照传统的施工方法,都是先制好本模,然后再浇筑混凝土。对于弯曲型尾水管,由于断面渐变异型扩张,管壁曲面变化复杂,使木模制造比较困难。同时,制造木模不仅耗用木材、铁钉等物料,而且还要配备具有一定施工经验和技术水平的木模工人。 The draft tube of hydropower station turbine is the basic project of hydropower station. According to the traditional construction method, the mold should be made first and then concrete. For the curved draft tube, due to the cross-section shaped abnormal expansion, complex changes in the surface of the pipe wall, making wood mold making more difficult. At the same time, the manufacture of wooden molds not only consume wood, nails and other materials, but also with a certain construction experience and technical level of woodworking workers.
