软土地区航道驳岸排桩预应力锚索挡墙施工技术

Channel Revetment Piles with Pre-stressed Anchor Cable Retaining Wall Construction Technology in Soft Soil Area

预应力锚索广泛应用于基坑明挖支撑体系、软岩、土体边坡加固工程中,但与钻孔排桩相结合应用于海相沉积层软土地区的航道护岸工程中的实例较少。结合连云港盐灌船闸下游远调站及紧邻的142m驳岸挡墙钻孔排桩锚索支护体系施工实例,主要阐述了钻孔排桩及预应力锚索在软土地区堤岸工程中的工艺技术要点及排桩锚索挡墙结构在软土地区的优越性。

Prestressed anchor cable is widely used in foundation pit support system, soft rock, and soil slope reinforcement projects.But this kind of prestressed anchor cable which combines bored piles was rarely applied in channels’bank protection projects in marine sedimentary layer soft soil area. This piece related to the project ex-ample of 142m revetment with bored piles-Prestressed anchor cable support system which used in the transfer station downstream the LianYunGang Shiplock and it’s adjacent areas.This shiplock is located in city of LianYun-Gang ,connects the two counties of SaltCity and GuanNan.This paper mainly discusses The key points of Technol-ogy and superiority of bored piles with Prestressed anchor cable which used in the area of soft soil embankment projects.
