Steel pipe curtain auxiliary pile foundation hole forming construction technology
The invention discloses a steel pipe curtain auxiliary pile foundation hole forming construction technology. Comprising the following steps of construction preparation, site leveling, pile position alignment, pile foundation center point measurement and lofting, four positioning steel pipes measurement and lofting, drilling machine platform treatment, drilling machine in-place and drilling, completion of four positioning steel pipes, welding of inner stirrups and the steel pipes, completion of driving of all curtain steel pipes, construction of lock openings in the top ends of the curtain steel pipes, and construction of the lock openings in the top ends of the curtain steel pipes. And the inner-layer stirrups are welded, and the annular steel pipe curtain is formed. The annular steel pipe curtain is used for resisting the lateral supporting force of surrounding sludge, the side pressure of soft soil sludge and soft soil floating can be effectively resisted, and the safety of pile foundation hole forming construction in the annular steel pipe curtain and the stability of the structure are guaranteed. And the steel pipe curtain can be repeatedly used, the construction cost is saved, the construction period is short, and the construction efficiency is improved.
本发明公开了一种钢管帷幕辅助桩基成孔施工工艺，包括如下步骤：施工准备、场地平整、对定桩位、桩基中心点测量放样、对四根定位钢管测量放样、钻机平台处理、钻机就位并打钻、完成四根定位钢管、将内箍筋与钢管焊接、完成所有帷幕钢管打入、在帷幕钢管顶端施工锁口、完成焊接内层箍筋并形成环形钢管帷幕。本发明利用环形钢管帷幕来对抗周围淤泥的侧向支撑力，能够有效抵抗软土淤泥侧压力和软土上浮，保证环形钢管帷幕内部桩基成孔施工的安全和结构的稳定性。而且钢管帷幕可多次周转使用，节约施工成本，且工期短，提高了施工效率。
