Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified as follows:
Fig. 1 .1～1.3; For the engineering that n Jacking point position arranged; The present technique scheme has comprised the n group equipment in the engineering, and every group equipment comprises: nut, dial gauge magnet base, dial gauge, the lifting jack of the suspension nut of H steel vertical beam, counter-force crossbeam, counter-force crossbeam nut, reinforcement, counter-force joist, counter-force joist nut, jacking column, suspension jacking column.Manual governing valve, lifting jack oil inlet pipe, lifting jack scavenge pipe.
Made up the framework of jacking column by H steel vertical beam, counter-force crossbeam, reinforcement and counter-force joist.
H steel vertical beam is in order to support the framework of jacking column, and the counter-force crossbeam supplies suspention jacking column counter-force in order to constitute; Reinforcement is in order to reinforce the framework of jacking column.The suspension nut of jacking column vertically passes the reach through hole on reach through hole on the counter-force crossbeam, the reach through hole on the reinforcement, the jacking upright column bracket position, the reach through hole on the counter-force joist.Lifting jack places on the plane of counter-force joist.Counter-force joist nut when the process of jacking is carried out, forms counter-force joist location to hold by the counter-force of jacking column.When lifting jack changes jobs stroke (that is: lifting jack shrinks the piston rod of full scale jacking), counter-force joist nut is up moved.Make on the counter-force joist and move, so that set up the counter-force point of next jacking impulse stroke.The nut of suspension jacking column be used for lifting jack line feed journey (piston rod of the lifting jack that at this moment is retracted has broken away from by the column of jacking, and the counter-force joist also moves on to the position on not) intermittently in, suspension is lived by the column of jacking.Lifting jack is in order to produce the power of jacking buildings column, stretches out the buildings column by jacking along with jack piston rod.In the jacking process, the jacking column is to top offset, and it is motionless that the nut of suspension jacking column rests on original position, and the jacking column has left the nut of suspension jacking column gradually, and this nut does not stress.It does not influence by the upwards displacement movement of jacking column, and when lifting jack changed jobs stroke, the nut rotation direction top of suspension jacking column was in order to hang by the column of jacking.Counter-force joist nut rotation direction top is in order to again to the location of counter-force joist.
The magnet base of dial gauge is installed on the H steel vertical beam with the mode of magnetic, and follows each time " jacking impulse stroke " constantly along H steel vertical beam upward displacement.(that is: lifting jack is changed impulse stroke each time; Percentage just table magnet base just once along H steel vertical beam upward displacement) the table body earrings of dial gauge is installed on the dial gauge magnet base; On the sounding rod contact of dial gauge and the platform at jacking upright column bracket position, to measure by the resetting of post amount of jacking.
Said bottom bracket is the concrete component of made before the jacking engineering construction.
