本发明涉及混凝土浇筑技术领域，具体公开了一种房建桩基施工混凝土浇筑装置，包括漏斗和固定安装在漏斗底部并插入桩孔内与桩孔中心相垂直的导管，导管外侧滑动安装有安装架，安装架底部设置有定位稳固单元和一体化对中单元，通过对中组件对钢筋笼进行夹持对中，使其能够在浇筑时以及浇筑后位于桩基中部，从而有助于提高浇筑后桩基结构的整体强度和稳定性，能够充分发挥钢筋笼的抗拉作用，与混凝土共同承担外部荷载，提高桩基的承载能力，同时此时的钢筋笼、桩孔和导管三者中心重合，当钢筋笼、桩孔和导管三者中心完全重合时，可以最大限度地减少因中心位置偏差导致的混凝土浇筑不均匀问题。

The invention relates to the technical field of concrete pouring, and particularly discloses a house building pile foundation construction concrete pouring device which comprises a funnel and a guide pipe fixedly mounted at the bottom of the funnel, inserted into a pile hole and perpendicular to the center of the pile hole, a mounting frame is slidably mounted on the outer side of the guide pipe, and a positioning stabilizing unit and an integrated centering unit are arranged at the bottom of the mounting frame. The reinforcement cage is clamped and centered through the centering assembly, so that the reinforcement cage can be located in the middle of the pile foundation during pouring and after pouring, the overall strength and stability of the pile foundation structure after pouring are improved, the tensile effect of the reinforcement cage can be fully exerted, the reinforcement cage and concrete jointly bear external loads, and the bearing capacity of the pile foundation is improved; meanwhile, the centers of the reinforcement cage, the pile hole and the guide pipe coincide, and when the centers of the reinforcement cage, the pile hole and the guide pipe coincide completely, the problem of uneven concrete pouring caused by center position deviation can be reduced to the maximum extent.
