Multi punching device for grouting method to road subsided by weak ground

摘要

The present invention can easily and easily perform the perforation work for grout solution injection in applying the grouting method in the ground settlement according to the traffic load of the vehicle or the weakening of the road surface, and to prevent various safety accidents The present invention relates to a composite punching apparatus for applying a grouting method to a road which is settled by weakening the ground to drastically reduce manpower and material resources required for drilling, A plurality of support frames 200 fixed on the upper side of the base frame 100 and vertically mounted and fixed with C-shaped steel facing each other, And power is applied to the drill driving unit 700 and the core drill driving unit 800 which are detachably mounted to the elevating cylinder 410 and the combined punching unit and the operation of the elevating cylinder 410 is operated A lifting unit 400 for lifting and lowering the lifting frame 500 by operating the power supply unit 300 while operating the power supply unit 300, A lifting frame 500 integrally fixed to the lifting and lowering part 400 and being lifted and lowered for a certain period of time during driving of the lifting part 400 and a lifting frame 500 integrally fixed and interlocked with the lifting frame 500, In which the drive means 700 is detachably installed And a pair of left and right mounting frames 600 provided with a clamping part 610 to which the core drill driving means 800 is detachably mounted.
