Prestressed supporting rod for foundation pit support
The invention discloses a prestressed supporting rod for foundation pit support. The prestressed supporting rod comprises a supporting seat, a telescopic seat, a supporting pipe, a connecting flange,a wedge and a jack. According to the prestressed supporting rod for foundation pit support, the prestress supporting rod is decomposed into the basic structure of the supporting seat, the telescopic seat, the supporting pipe and the connecting flange, the basic structure is conveniently combined into a telescopic pipe, a middle connecting pipe and an anchoring pipe, the supporting seat is combinedwith the telescopic pipe, and the wedge and the jack are matched to form a prestress applying section of the supporting rod; the telescopic pipe is combined with one or more middle connecting pipes to form a length adjusting section of the supporting rod; and the middle connecting pipe is combined with the anchoring pipe, and the supporting rod is inserted below the bottom of a foundation pit toform an anchoring section through grouting reinforcement. The prestressed supporting rod for foundation pit support has the advantages that the structure is simple, practicability and convenience areachieved, the construction period is short, and deformation of the foundation pit support can be corrected in the foundation pit excavation process.
本发明公开了一种基坑围护的预应力支撑杆，包括支撑座、伸缩座、支撑管、连接法兰、楔铁及千斤顶；本发明采用将预应力支撑杆分解为支撑座、伸缩座、支撑管及连接法兰的基本构建，由基本构建便捷组合成伸缩管、中间接管及锚接管，将支撑座与伸缩管结合，配合楔铁及千斤顶构成支撑杆的预应力施加段，将伸缩管与一根或多根中间接管结合，构成支撑杆的长度调节段，将中间接管与锚接管结合，构成支撑杆插入基坑底以下采用注浆加固形成锚段。本发明具有结构简单，实用方便，施工周期短及在基坑开挖过程中可以对基坑围护的变形进行修正的优点。
