Controllable and stable-pressurization columnar bag body pressurization device and controllable and stable-pressurization columnar bag body pressurization method
The invention discloses a controllable and stable pressurizing columnar bag pressurizing device and method, belongs to the field of highway engineering, and is used for lifting the ground in a grouting manner to restore the original height of a road surface after a tunnel is excavated below an existing highway. The controllable and stable pressurizing columnar bag pressurizing device comprises bag bodies, a gas-liquid inlet pipeline, a gas-liquid outlet pipeline, a steel sleeve, a gas-liquid control device, a steering motor, a scanning camera and a driving device, the columnar bag bodies in rows are mounted by drilling holes below a road surface and above a tunnel, and the scanning camera is driven by the driving device to detect the road surface condition. And then the gas-liquid control device is fed back to control grouting to finish controllable stable lifting of the sunken ground, and settlement of the road ground can be eliminated. The method overcomes the problems of random diffusion of grout and grout water seepage after grouting in traditional underground grouting operation, and has the remarkable advantages of controllable grouting direction, controllable effect and the like.
本发明公开了一种可控式稳定增压的柱状囊体增压装置及方法，属于公路工程领域，用于已有公路下方挖掘隧道完工后，通过向注浆方式将地面抬升，使路面恢复原有高度。可控式稳定增压的柱状囊体增压装置包括囊体、进气液管道、排气液管道、钢套管、气液控制装置、转向电机、扫描相机、驱动装置，通过在路面下方、隧道上方钻孔安装成排柱状囊体，通过驱动装置驱动扫描相机检测路面情况，然后反馈给气液控制装置控制注浆完成凹陷地面的可控稳定抬升，可以消除公路地面的沉降。该方法克服了传统地下注浆作业中浆液的随机扩散及注浆后浆液渗水问题，具有注浆方向可控，效果可控等显著优势。
