The working principle is as follows:
firstly, a construction fence is placed on the ground around a construction site, then a pulling rope 713 is pulled through a pulling ring 714, then a driving rope 712 is pulled through the pulling rope 713, then the driving rope 712 bends and deforms and pulls two displacement blocks 711 to approach each other, meanwhile, the two displacement blocks 711 do work on an elastic steel ring 716, the elastic steel ring 716 gradually becomes elliptical and elastic potential energy is increased, then the displacement blocks 711 drive the one-way clamping joints 715 to be far away from the take-up wheel 704, then the one-way clamping joints 715 are separated from the limiting ratchets 705, then the take-up wheel 704 is released, then the expansion strips 82 are ejected out from the interior of the reinforcing flat tubes 81 under the action of elastic repulsion force of the expanding springs 84, then the right end face of the piston column 85 is in contact with the right side face of the inner cavity of the installation cavity 83, at the moment, the expansion strips 82 are displaced to the dead point position relative to the reinforcing flat tubes 81, then the pulling ring 714 is released, and then the elastic steel ring 716 is elastically restored to be circular, then the elastic steel ring 716 pushes the displacement block 711 to move and reset in the process of elastic recovery, then the displacement block 711 drives the one-way clamping joint 715 to reset and engage with the limit ratchet 705 in one way, then a second construction fence is taken and placed on the side surface of the first construction fence, then the downward conical groove 22 on the second construction fence is sleeved on the conical jacking head 35 on the first construction fence, then the upward conical groove 22 on the second construction fence is aligned with the through hole 42 on the first construction fence, then the operating device 5 on the first construction fence is pressed until the bottom surface of the displacement piston 501 is in contact connection with the top surface of the upper limit retainer ring 49, then the guide piston 505 drives the ratchet-type clamping joint 506 to move outwards under the action of the elastic repulsion force of the compression spring 504, and then the ratchet-type clamping joint 506 is in one-way engagement with the ratchet-type groove 40, fixing the operating device 5, in the process, the operating device 5 applies work to the pressure spring 45, then the pressure spring 45 elastically compresses, the elastic potential energy is increased, then the pressure of the pressure spring 45 on the reset piston 44 is increased, then the pressure of the reset piston 44 on the reset spring 43 is increased, then the reset spring 43 elastically compresses, then the reset piston 44 carries the conical pressure applying head 47 to move downwards through the pressure applying column 46, then the conical pressure applying head 47 and the pressure applying column 46 sequentially pass through the through hole 42, then the conical pressure applying head 47 is inserted into the corresponding conical groove 22, then the bottom surface of the reset piston 44 is in contact connection with the top surface of the lower limit retainer ring 48, at the moment, the two construction fences are movably connected together through the matching of the socket device 2, the lower locking device 3, the upper locking device 4 and the operating device 5, then the pulling ring 714 on the second construction fence 1 is pulled, and the corresponding expansion strip 82 is ejected, the installation is repeated as above until the construction fence movably connected can enclose the construction site, the installation process is completed, when the construction fence is subjected to a large enough external force in the use process, a large enough shearing force exists between the construction fence directly stressed and the adjacent construction fence, the shearing force is generated due to the inertia force of the construction fence, then the inner wall of the conical groove 22 exerts pressure on the conical jacking head 35 and the conical pressure applying head 47 under the action of the shearing force, then the pressure exerts downward pressure on the conical jacking head 35 under the matching action of the inner wall of the conical groove 22 and the surface of the conical jacking head 35, then the conical jacking head 35 moves downward and applies work on the jacking spring 32 through the jacking column 34 and the jacking piston plate 33, then the elastic potential energy of the jacking spring 32 is increased, and meanwhile the pressure exerts upward thrust on the conical pressure applying head 47 under the matching action of the inner wall of the conical groove 22 and the surface of the conical pressure applying head 47, then the conical pressure applying head 47 moves upwards, then the conical pressure applying head 47 applies work to the return spring 43 and the pressure applying spring 45 through the pressure applying column 46 and the return piston 44, then the return spring 43 elastically extends, the elastic potential energy is reduced, meanwhile, the pressure applying spring 45 further elastically compresses, the elastic potential energy is increased, then the conical jacking head 35 and the conical pressure applying head 47 both slide out from the inner part of the conical groove 22, so that the construction fence directly stressed is separated from the adjacent construction fence, then the construction fence 1 directly stressed drives the arc-shaped traction sleeve 67 to turn over along the arc-shaped cylinder 61 anticlockwise, then the arc-shaped traction sleeve 67 pulls the traction spring 64 through the traction wing plate 66 and the traction piston 65, the elastic potential energy of the traction spring 64 is increased, the purposes of elastic buffering and energy absorption are achieved, the construction fence 1 is protected, and then after the external force applied to the construction fence 1 is removed artificially, the drawing piston 65 drives the construction fence 1 to turn clockwise through the drawing wing plate 66 and the arc-shaped drawing sleeve 67 under the action of elastic tension of the drawing spring 64, then the two socket devices 2 respectively apply thrust to the conical jacking head 35 and the conical pressure applying head 47 to enable the conical pressure applying head 47 to move towards the inside of the upper locking barrel 41, the conical jacking head 35 moves towards the inside of the lower locking barrel 31 until the arc-shaped drawing sleeve 67 is in contact with the positioning retainer ring 63, at the moment, the construction fence 1 is in a vertical state, then the conical jacking head 35 is inserted into the corresponding conical groove 22 again under the action of the elastic force of the jacking spring 32, meanwhile, the conical pressure applying head 47 is inserted into the corresponding conical groove 22 again under the action of the elastic force of the pressure applying spring 45, and then the construction fence 1 directly stressed is reset.
