高压旋喷桩在涵洞加固处理中的应用

Application of Hyperpressure Swiveling Nozzle Pile in the Treatment of Culvert

某高速公路一涵洞由于基础出现不均匀沉降,造成涵洞盖板、八字墙与墙身发生错位,严重影响了行车的安全,必须进行加固处理;通过方案比较,该涵洞采用高压旋喷桩进行加固处理。文中通过介绍高压旋喷桩在涵洞软基加固中的应用,为同类工程的施工提供参考。

Uneven settlement in culvert have caused stagger of caps and splayed jambs in some freeway, which affected the safety of traveling crane and must be strengthened. By comparing different methods, this culvert adopted hyperpressure swiveling nozzle pile to steengthen the culvert, it can give reference for the construction of similar englneenngs.
