Pile foundation concrete over-pouring prevention device and construction method
The invention belongs to the technical field of pile foundation construction, and particularly relates to a pile foundation concrete over-filling prevention device and a construction method, the pile foundation concrete over-filling prevention device comprises a pile filling feed hopper, and the bottom of the pile filling feed hopper fixedly communicates with a rotary discharging valve. According to the pile foundation concrete over-pouring prevention device and the construction method, the pile pouring shrinkage driving control mechanism and the pile pouring monitoring mechanism are arranged, when concrete pouring construction is conducted on a pile foundation, the controller automatically controls the pile pouring shrinkage driving control mechanism to be matched with the rotary discharging valve, discharging and pile pouring are conducted while pipe drawing is shrunk, and the construction efficiency is improved. And the concrete pressure of the grouting pile is monitored through the grouting pile monitoring mechanism, and the situation that the grouting concrete pressure is too large, consequently, the diameter of a pile body is increased, and an upper pile hole where concrete is not poured is collapsed is prevented, so that the problem that in the existing pile foundation construction process, the concrete grouting amount and pressure of the concrete poured into the pile hole cannot be effectively monitored, and the construction cost is lowered is solved. Not only is the pile foundation grouting construction influenced, but also the bearing capacity and the stability of a formed pile are influenced.
本发明属于桩基施工技术领域，尤其是一种桩基混凝土防超灌装置及施工方法，包括灌桩进料斗，所述灌桩进料斗的底部固定连通有旋转下料阀。该桩基混凝土防超灌装置及施工方法，通过设置灌桩收缩驱动控制机构和灌桩监测机构，在对桩基进行混凝土灌注施工时，通过控制器自动控制灌桩收缩驱动控制机构和旋转下料阀配合，实现边下料灌桩边收缩抽管，并通过灌桩监测机构对灌桩的混凝土压力进行监测，防止灌注的混凝土压力过大，导致桩身直径增大，和导致未灌注混凝土的上部桩孔坍塌，从而解决了现有的桩基施工过程中，无法对桩孔灌注混凝土的混凝土灌注量和压力进行有效监测，不仅会影响桩基灌桩施工，还会影响成桩的的承载能力和稳定性的问题。
