复杂海相地质条件下的咬合桩施工关键技术

Key Technology of Secant Pile Construction Under Complex Marine Geological Conditions

为解决复杂地质条件下的咬合桩施工难题,以深圳城市轨道交通13号线深圳湾口岸站—登良东站明挖区间围护桩施工为载体,在保证质量、安全等基本前提下,通过科学管理、设备合理组合、优化混凝土配比和工艺改进等措施,形成了沿海城市复杂海相地质条件下的咬合桩施工关键技术。该技术可为类似工程提供借鉴。

In order to solve the problem of secant pile construction under the complicated geological conditions,taking the support pile construction in the open excavation section between Shenzhen Bay Port Station and Dengliang East Station of Shenzhen rail transit line 13 as the carrier,under the basic premise of ensuring the quality and safety,and through the measures of scientific management,reasonable combination of equipment,optimization of concrete ratio and process improvement,the key construction technology of secant pile under the complicated marine geological conditions in the coastal cities is formed,which can provide a reference for similar projects.
