Annular reinforcing method for thick sand layer pile foundation
The invention discloses an annular reinforcing method for a thick sand layer pile foundation. The annular reinforcing method for the thick sand layer pile foundation comprises the steps that when the pile foundation is filled through the annular reinforcing method for the thick sand layer pile foundation, punching and sampling are conducted on a supporting point of a preset pile foundation at the bridge erection position, the position of the preset pile foundation is determined at the bridge erection position according to geological survey data, a foundation pit and a base pit are excavated through a rotary drilling rig, a curing agent is sprayed into the foundation pit and the base pit through a stirring pile machine, cement is sprayed into a soil body and fully stirred, soft soil is hardened, and the foundation strength is improved; and an anchoring assembly and a base are inserted into the cured foundation pit and the cured base pit correspondingly, concrete is poured into the foundation pit and the base pit, a damping assembly is assembled, connected and fixed to the base, two semicircular steel plates are transported to a construction site and assembled into a sealing base, and a damping device is isolated outside the sealing base. According to the annular reinforcing method for the thick sand layer pile foundation, a reinforcing platform is arranged, so that the stability of using and supporting of the pile foundation in the later period is improved, and the annular reinforcing method for the thick sand layer pile foundation can be used in a complex soft environment conveniently.
本发明公开了一种厚砂层桩基的环形加固方法，包括在使用该厚砂层桩基的环形加固方法加注桩基时，通过在桥梁架设位置预设桩基的支撑点上进行打孔取样，根据地质勘测的数据，在桥梁架设位置上确定预设桩基的位置，通过旋挖钻机挖掘基坑和基座坑，利用搅拌桩机在基坑和基座坑喷入固化剂，水泥喷入土体并充分搅拌，使软土硬结而提高地基强度，通过在固化后的基坑和基座坑中分别插入锚定组件和基座，在的基坑和基座坑中浇筑混凝土，在基座上组装连接固定减震组件，将两块块半圆钢板运输至施工现场，并将两块半圆钢板组装密封座，将减震装置隔断在密封座外。本发明设置加固平台，从而提升后期桩基使用支撑的稳定性，便于在复杂松软环境下进行使用。
