External expansion arm grouting cement paste reinforcing device
The invention discloses an external expansion arm grouting cement paste reinforcing device. The device comprises a mud jacking pipeline and a mud jacking pipe, wherein the mud jacking pipeline is arranged on the outer side wall of a to-be-reinforced workpiece; a piston connecting key is arranged in the mud jacking pipeline; the external expansion arm is connected with the bottom of the mud jacking pipeline, and an external expansion arm connecting key is arranged on the external expansion arm; the external expansion arm connecting key is connected with the piston connecting key through a connecting part; a plurality of mud jacking holes are formed in the external expansion wall and are used for spraying cement paste in the mud jacking pipeline; the servo electric cylinder is connected with the piston connecting key through a push rod and used for pushing the piston connecting key to move downwards so that the external expansion arm can move away from the mud jacking pipeline. The external expansion arms are arranged on the side wall of the to-be-reinforced workpiece, the cement paste is sprayed to the soil body by opening the external expansion arms, and when the cement paste is solidified, the cement paste, the external expansion arms and the to-be-reinforced workpiece form a reinforced body, so that the horizontal and vertical bearing capacity of the to-be-reinforced workpiece is improved.
本发明公开了一种外扩臂灌注水泥浆加固装置。该装置包括：压浆管道，所述压浆管道设置于待加固工件的外侧壁上；于所述压浆管道内设置有活塞连接键；外扩臂，所述外扩臂与所述压浆管道的底部连接，于所述外扩臂上设置有外扩臂连接键；所述外扩臂连接键与所述活塞连接键通过连接部件连接；于所述外扩壁上设置有多个压浆孔，用于将所述压浆管道内的水泥浆喷射；伺服电缸，所述伺服电缸通过推杆与所述活塞连接键连接，用于推动所述活塞连接键下移以使所述外扩臂远离所述压浆管道移动；本发明在待加固工件侧壁设置外扩臂，通过张开外扩臂向土体喷射水泥浆，当水泥浆凝固时，其与外扩臂以及待加固工件形成加固体，从而提高待加固工件的水平与竖向承载力。
