Over-cast-in-place concrete treatment device and underwater concrete cast-in-place pile construction technology
The invention relates to an over-cast-in-place concrete treatment device and an underwater concrete cast-in-place pile construction technology, and relates to the technical field of cast-in-place piles. The over-cast-in-place concrete treatment device comprises a hollow mounting shell with one open end, a feeding port is formed in one end, away from the open end, of the mounting shell, a cutting mechanism used for opening and closing the feeding port is arranged on a portion, close to the feeding port, of the mounting shell, and a driving mechanism used for driving the cutting mechanism is arranged on the mounting shell. The construction technology comprises the following steps: conducting drilling and placing a reinforcement cage; mounting the over-cast-in-place concrete treatment device; enabling cast-in-place concrete to exceed a designed elevation position of a cast-in-place pile; cutting concrete: driving the cutting mechanism to work to cut the concrete through the driving mechanism; and dismantling the over-cast-in-place concrete treatment device. The underwater concrete cast-in-place pile construction technology has advantages of reducing difficulty of breaking a pile head of the cast-in-place pile to improve construction quality and efficiency.
本申请涉及一种超灌混凝土处理装置及水下混凝土灌注桩施工工艺，涉及灌注桩技术领域，其中超灌混凝土处理装置包括内部中空、一端敞口的安装壳，所述安装壳远离敞口的一端开设有进料口，所述安装壳靠近进料口的部位安装有用于启闭进料口的切割机构，所述安装壳安装有用于驱动切割机构的驱动机构；施工工艺包括钻孔并放置钢筋笼；安装超灌混凝土处理装置；灌注混凝土超过灌注桩的设计标高位置；切割混凝土：通过驱动机构带动切割机构工作切割混凝土；拆除超灌混凝土处理装置。该申请具有减小破除灌注桩桩头难度以提高施工质量和效率的优点。
