Abstract

The invention relates to a water conservancy project river channel slope protection cast-in-place concrete construction method and device, and belongs to the technical field of embankment renovation slope protection. According to the construction method, concrete pouring is conducted on a river bed slope protection in an interval construction mode, so that a slope protection working face is artificially divided into a plurality of working units, quality control of all the working units is facilitated, and the construction efficiency is improved. The construction efficiency is improved, and meanwhile, in the concrete compacting and trowelling operation, the concrete is pre-paved and tamped through a paver; the dragger drags and moves the jolt ramming and trowelling machine to complete jolt ramming and trowelling operation, and the problems that existing slope protection construction adopts a manual mode, time and labor are wasted, and the construction efficiency is low; and the construction quality and the engineering progress of the river channel slope protection are influenced. And on the other hand, due to the fact that the slope protection working face is artificially divided into the multiple working units in an interval construction mode, the phenomenon of idling of workers can be reduced, daily maintenance of all the working units is facilitated, and the forming quality of concrete is improved.

本发明涉及一种水利工程河道护坡现浇混凝土的施工方法及施工装置,属堤防整治护坡技术领域.该施工方法采用间隔施工的方式对河床护坡进行混凝土浇筑，使得护坡作业面被人为分割成多个作业单元,有利于各作业单元的质量把控,提高施工效率,同时,在混凝土振实抹平作业中,通过摊铺机对混凝土进行预摊铺和捣实；通过牵引机对振实抹平机的牵引移动,完成振实、抹平作业，解决了现有护坡施工采用人工方式，不仅费时费力，且施工效率低；影响河道护坡施工的质量和工程进展的问题。另一方面，由于本发明采用间隔施工的方式将护坡作业面人为分割成多个作业单元,不仅可减少窝工现象，且方便各作业单元的日常维护，有利于混凝土的成形质量。
