Pile foundation construction method under complex geological conditions
The invention provides a pile foundation construction method under a complex geological condition, and aims to provide a pile foundation construction method which is convenient to demould under the complex geological condition, does not need pre-demoulding, is demoulded after the concrete strength reaches the standard, and is used for grouting a cavity generated by pulling through an embedded air pipe during pulling, so that the construction efficiency is improved. According to the technical scheme, the pile foundation construction method under the complex geological condition comprises the following steps that S1, a long pile casing is put down, S2, standard joints are manufactured, S3, the standard joints are connected, S4, pouring pieces are put down, S5, concrete is poured, S6, the long pile casing is pulled out, S7, primary grouting is conducted, S8, pulling out is conducted again, S9, grouting is conducted again, and S8-S9 are repeated till the long pile casing is completely pulled out to the ground.
本发明提供了复杂地质条件下桩基施工工法，目的是提供一种在复杂地质条件下便于脱模，不需要预脱模，在混凝土强度达标后再进行脱模，并且在拔起时对拔起产生的空腔处通过预埋气管进行注浆，避免空腔带来的桩基偏移风险的复杂地质条件下桩基施工工法，本发明的技术方案是，包括以下步骤：S1长护筒下放、S2标准节制作、S3标准节连接、S4浇筑件下放、S5混凝土灌注、S6起拔长护筒、S7初次注浆、S8再次起拔、S9再次注浆，重复S8‑S9，直到长护筒完全起拔至地面。
