Complex interactive silty-fine sand layer super-long large-diameter pile foundation protective cylinder and construction method
The invention belongs to the technical field of building construction. The invention discloses a complex interactive silty-fine sand layer super-long large-diameter pile foundation protective cylinder. The complex interactive silty-fine sand layer super-long large-diameter pile foundation protective cylinder comprises an upper protective cylinder, a lower protective cylinder, grouting pipes and sealing pipes, the lower protective cylinder is arranged in the upper protective cylinder in a matched and penetrating mode, and a supporting assembly is arranged between an upper end of the lower protective cylinder and a lower end of the upper protective cylinder; a plurality of the grouting pipes are distributed in a circumferential direction of the lower protective cylinder; and a plurality of the sealing pipes are distributed in the circumferential direction of the lower protective cylinder and lateral nozzles facing outer sides are formed in the grouting pipes and the sealing pipes. The invention further discloses a complex interactive silty-fine sand layer super-long large-diameter pile foundation construction method The complex interactive silty-fine sand layer super-long large-diameter pile foundation protective cylinder construction device has a reasonable structural design, can effectively increase a construction speed, improves construction safety, avoids a construction quality problem caused by interaction of silty-fine sand layers, can realize cyclic utilization, and is more economical and practical.
本发明属于建筑施工技术领域。一种复杂交互粉细砂层超长大直径桩基护筒，包括上部护筒、下部护筒、注浆管和密封管，所述下部护筒匹配穿设在所述上部护筒中，且所述下部护筒的上端与所述上部护筒的下端之间设置有支撑组件；在所述下部护筒的周向布设有多道注浆管；在所述下部护筒的周向布设有多道密封管，在各所述注浆管和所述密封管上均开设有朝向外侧的侧向喷口。还公开了一种复杂交互粉细砂层超长大直径桩基施工方法。本申请结构设计合理，能够有效的提高施工速度，提高施工的安全性，避免因为交互粉细砂层导致施工质量问题，并且能够实现循环利用，更为经济实用。
