The present invention provides a whole-space drilling-grouting integrated device, comprising: a traveling mechanism comprising a drilling-grouting mechanism of which one side is provided with a rod-changing robotic arm and comprising an adjusting mechanism; the adjusting mechanism is connected to a platform that connected to a supporting platform through a drilling-moving mechanism; an output shaft of a power mechanism fixed on the supporting platform is detachably connected with a drilling tool; a first drilling tool clamping mechanism arranged at tail end of the platform is connected to arc-shaped guide rail arranged on the platform in a sliding way and is further connected to rotating driving member of the platform so as to realize rotation around an axis of output shaft of the power mechanism; and, a second drilling tool clamping mechanism fixedly connected to tail end of the platform where far away from power head.

Whole-space drilling-grouting integrated device

The present invention provides a multi-pump linkage grouting operating system, including a slurry storage unit including a plurality of slurry storage tanks and a grouting unit including a plurality of grouting pumps; wherein, an inlet of each grouting pump is connected to main slurry inlet pipe, the main slurry inlet pipe is connected to a plurality of branch slurry inlet pipes connected to an outlet of corresponding slurry storage tank; grouting on-off valves are mounted on the branch slurry inlet pipes, each branch slurry inlet pipe is further connected to one end of a cleaning pipe, a connection position between the cleaning pipe and the branch slurry inlet pipe is located downstream of the grouting on-off valve on the branch slurry inlet pipe, the other end of the cleaning pipe is connected to a water tank, and a cleaning on-off valve is mounted on the cleaning pipe.

Multi-pump linkage grouting operating system

A multi-dimensional space load and fire test system for a tunnel structure, which includes a multi-point loading self-balancing reaction force system having a rigid platform, two furnace body side-sealing apparatuses () and a model assembly and transport apparatus () for transporting and situating a tunnel model are on a track on the rigid platform (), the two furnace body side-sealing apparatuses () are respectively used for sealing two end openings of the tunnel model, a tower-type combustion vehicle can be placed within an inner cavity of the tunnel model, a plurality of sets of evenly distributed self-adaptive loading apparatuses () used for exerting loading forces on an outer wall of the tunnel model are connected between two reaction force frames () of the multi-point loading self-balancing reaction force system. The present system is able to perform loading on tunnel models having different cross section shapes, can be adapted to testing requirements of tunnel structures having different cross section shapes, and with respect to tunnel structure fire testing in particular, a camera of the present system has a large imaging angle of view, the present invention has good heat resistance, possesses both terminal imaging and distance measurement, and can amply satisfy a use requirement for the high temperature environment of a tunnel fire.
