摘要:

工程采用三轴搅拌桩围护截水方案, 设计为双排三轴搅拌桩止水帷幕, 止水帷幕选用Φ850@1 200 mm三轴

搅拌桩, 施工过程对测量定位、水泥掺入比、搅拌下沉上升速度、冷缝等严格控制, 采用技术措施有效解

决了施工过程中出现的预搅下沉困难、垂直度难以控制、浆管堵塞、意外停机等问题, 经检测成桩质量符

合规范和设计要求。地下工程施工期间, 地下围护结构止水状况良好, 保证了地下工程的顺利施工。

Abstract:

The project adopts three-axis mixing pile enclosing water scheme, designed as a double-row

three-axis mixing pile water interception curtain.The water interception curtain

adoptsΦ850@1200mm threeaxis mixing pile.During construction process, measurement

positioning, the ratio of cement mixing, rate of descending and ascending mixing rate and

cold joint are strictly controlled.The technical measures applied effectively help solve the

problems of pre-stirring and sinking difficulties during construction, difficulty in

controlling verticality, blockage of slurry pipes, unplanned shutdown, etc.Through detection,

the quality of piling meets the requirement of specifications and design.During the

construction of underground projects, the underground retaining structure renders a proper

water interception condition, which ensures the smooth construction of underground projects.
