Cross-blade type concrete buffering chute
The invention discloses a cross-blade type concrete buffering chute. The chute comprises metal baffles, a U-shaped chute body, square timbers, combined positioning steel plates and cross blades, the rectangular metal baffles are symmetrically arranged on the two sides of a notch of the U-shaped chute body and fixed by welding, a welding angle is 45 degrees anticlockwise along the notch of the U-shaped chute body, the combined positioning steel plates are welded to the end of the U-shaped chute body, an inclination angle of the U-shaped chute body in use is determined by adjusting the combinedpositioning steel plates in advance, the flow speed of concrete in the U-shaped chute body is controlled, the cross blades are evenly arranged at the bottom of the U-shaped chute body in inverted-triangle shapes, and by means of automatic buffering of the inverted-triangle structures of the cross blades, the flow speed of the concrete is effectively reduced, and three square timbers evenly distributed in the transverse direction are installed on the back of the U-shaped chute body. The chute is simple in structure and capable of being repeatedly used, and the technical problems that when the concrete pouring height difference of a deep foundation pit of a bearing platform is larger than 2 m, the concrete flow speed is too high, and consequently the concrete segregation happens and bearingplatform steel bars are damaged are effectively solved.
本发明公开了一种十字叶片式缓冲混凝土溜槽，包括金属挡板、U形溜槽、方木、组合定位钢板和十字叶片，U形溜槽槽口两侧对称设置有矩形的金属挡板，两者通过焊接进行固定，焊接角度为沿U形溜槽槽口逆时针45°，U形溜槽的端部焊接有组合定位钢板，通过预先调节组合定位钢板，以确定U形溜槽在使用时的倾斜角度，控制混凝土在U形溜槽中的流速，十字叶片呈倒三角形均匀布置在U形溜槽的底部，借助十字叶片倒三角形结构的自动缓冲，有效降低了混凝土的流速，U形溜槽的背部安装有沿横向均匀布置的三个方木。本发明结构简单，能重复使用，有效解决了承台深基坑混凝土浇筑高差大于2m时，混凝土流速过快导致其离析和损伤承台钢筋的技术问题。
