在液压滑模施工中还存在着不同程度的质量问题,主要是模板停留时间太长,模板和混凝土表面摩阻力增大,出模后混凝土表面粗糙,甚至出现拉裂、松动、掉角等现象。为解决这一问题,除采用“滑框倒模”外,也可采用“转动模板”的施工方法。转动模板就是在原有模板结构增加转动装置(见图2)。转动装置包括滚筒、支架、转动带(如帆布或其他材料)。转动带处于模板和混凝土
There are different quality problems in the hydraulic sliding mode construction. The main problem is that the template residence time is too long, the frictional resistance of the surface of the formwork and the concrete increases, and the surface of the concrete after the moulding is rough, and even the phenomenon of cracking, loosening and falling angles occurs. . In order to solve this problem, in addition to the use of “sliding frame mold”, the “rotating formwork” construction method can also be used. Rotating the template is to add turning devices to the original template structure (see Figure 2). Rotary devices include rollers, holders, rotating belts (such as canvas or other materials). Turning strips in formwork and concrete
