Construction equipment for pouring concrete into karst cave

SHAO YUAN

The invention relates to the technical field of constructional engineering equipment, in particular to karst cave concrete pouring construction equipment which comprises a base, a positioning groove is formed in the center of the base, a guide device is arranged below the positioning groove, and a drilling device and a reinforcement cage placing device are arranged on the base and located on the two sides of the positioning groove respectively. Rollers are mounted on the lower surface of the base, the guide device comprises a left guide steel cylinder, a right guide steel cylinder, a guide rod and a screw, the left guide steel cylinder and the right guide steel cylinder are matched with each other to form the guide steel cylinder, the guide rod and the screw are horizontally fixed on the lower surface of the base, and fixing lugs are fixed on two sides of the left guide steel cylinder and two sides of the right guide steel cylinder. The equipment solves the problems that the main treatment mode of the current karst cave is to fill the cave body after drilling so as to reduce the risk of collapse caused by instability of the cave body structure, but a large amount of materials are wasted, and meanwhile, the current construction method needs to repeatedly hammer after filling, the construction equipment is complex, and the construction period is longer.

本发明涉及建筑工程设备技术领域，尤其涉及一种溶洞灌注混凝土的施工设备，包括有底座，底座的中心处开有定位槽，定位槽下方设置有导向装置，底座上且位于定位槽的两侧分别设置有钻孔装置和放钢筋笼装置，底座的下表面安装有滚轮，导向装置包括左导向钢筒、右导向钢筒、导向杆、螺杆，左导向钢筒、右导向钢筒相互配合可形成导向钢筒，导向杆、螺杆水平固定在底座的下表面，左导向钢筒、右导向钢筒的两侧均固定有固定耳，该设备解决了目前溶洞主要的处理方式是钻孔后将洞体填充，以降低洞体结构出现不稳定而塌陷的危险，但这往往会导致大量的材料浪费，同时，目前的施工方法需要在填充后反复锤实，施工设备复杂且工期较长的问题。
