Construction method for mobile pouring of self-discharging concrete of long open cut cast-in-place structure
The invention discloses a construction method for mobile pouring of self-discharging concrete of a long open cut cast-in-place structure, which comprises the following steps of: firstly, arranging a longitudinally moving mobile pouring platform above a foundation pit, and arranging concrete horizontal conveying equipment and a telescopic concrete chute tube communicated with the horizontal conveying equipment in the mobile pouring platform; secondly, the telescopic concrete chute tube is lowered to a to-be-poured point position set in the foundation pit; then, concrete is conveyed into the telescopic concrete chute tube through horizontal conveying equipment to complete pouring of the to-be-poured point position; and finally, the telescopic concrete chute tube is retracted, the movable pouring platform is moved to the next pouring point position, and the steps are repeated to complete movable pouring of the long, large and deep foundation pit open cut cast-in-place structure through the self-discharging concrete. The construction efficiency is improved, meanwhile, the concrete is not limited by the slump requirement any more, the risk of concrete cracking can be controlled by reducing the water-binder ratio, and the pouring quality of lining structure concrete is guaranteed.
本发明公开了一种用于长大明挖现浇结构自卸混凝土移动式浇筑的施工方法，包括：首先，在基坑上方设置纵向移动的可移动式浇筑平台，其内设置有混凝土水平输送设备以及与水平输送设备连通的可伸缩式混凝土溜筒；其次，将可伸缩式混凝土溜筒下放至基坑内设定的待浇筑点位；然后，将混凝土通过水平输送设备输送至可伸缩式混凝土溜筒内完成对待浇筑点位的浇筑；最后，将可伸缩式混凝土溜筒收回，移动可移动式浇筑平台至下一个浇筑点位，重复上述步骤完成利用自卸混凝土对长大深基坑明挖现浇结构的可移动式浇筑。本发明不仅提高了施工效率，同时混凝土不再受塌落度要求限制，可通过减少水胶比控制混凝土开裂的风险，保证了衬砌结构混凝土的浇筑质量。
