Inner drilling hole inserting pipe compaction grouting reinforcement device for pipe gallery bottom plate cavity repairing
The invention discloses an inner drilling hole inserting pipe compaction grouting reinforcement device for pipe gallery bottom plate cavity repairing. The inner drilling hole inserting pipe compaction grouting reinforcement device comprises a grouting pipe, an outer wall sleeve coaxially connected to a top pipe opening of the grouting pipe, and a grouting connecting pipe connected to the pipe wall of the outer wall sleeve; the grouting connecting pipe communicates with the interior of the outer wall sleeve, and the flow is adjusted through a pressure valve; the pipe diameter of the outer wall sleeve is larger than that of the grouting pipe, and bottom pipe openings are sealed through an annular plate; and the outer side edge of the bottom pipe opening of the outer wall sleeve is further connected with a positioning plate in a sealed manner, and the positioning plate is fixed to a pipe gallery bottom plate through an expansion bolt. The device is an inner drilling hole inserting pipe compaction grouting device, and pipe gallery bottom plate cavity repairing work is conducted in a high-pressure grouting manner; and the pipe gallery structure quality problem is solved, the problems about pipe gallery safety and related water permeability are avoided, and later comprehensive pipe gallery functional usage is not influenced.
本发明公开了一种用于管廊底板空洞修复的内钻孔插管压密注浆加固装置，其包括注浆管、同轴连接于所述注浆管顶部管口上的外壁套管以及连接于所述外壁套管管壁上的注浆连管，所述注浆连管与所述外壁套管内部连通且通过压力阀门调节流量，所述外壁套管的管径大于所述注浆管的管径且底部管口之间采用环形板密闭，所述外壁套管的底部管口的外侧边缘还密闭连接有定位板，所述定位板通过膨胀螺栓固定在管廊底板上。本发明装置为内钻孔插管压密注浆装置，依靠高压注浆方式进管廊底板空洞修复工作；以期解决管廊结构质量问题，避免管廊安全性及相关渗水性问题出现，不影响后期综合管廊功能性使用。
