As preferably, described longitudinal i iron is fixed with the horizontal i iron of multilayer by Z-direction i iron.Framework taken out by whole supporting mechanism i iron, and structure is simple, and intensity is stronger.
As preferably, the transverse direction longitudinal connecting rod of level on described heavy door frame being fixed with orthogonal setting fixes steel pipe, longitudinally fixing steel pipe, fix with right-angle coupler therebetween, be plugged with support steel pipe in the cavity that the longitudinal connecting rod of level, laterally fixing steel pipe, longitudinal fixing steel pipe surround.The heavy door frame in the effect Shi Nengbage road of support steel pipe is strutted, makes can not extrude mutually between each road supporting mechanism.
As preferably, be also provided with tunnel partition wall between described diaphragm wall, tunnel partition wall be fixed with thick iron plate, thick iron plate is connected with adjusting screw, and adjusting screw cross-under is in adjusting nut, and adjusting nut is connected on horizontal i iron.Can be adjusted the installation site of horizontal i iron by adjusting screw, thus can regulate the installation site of whole supporting mechanism, compliance is stronger.
As preferably, be provided with adjustable bracket between the lower end of described heavy door frame and tunnel floor, the below of tunnel floor is provided with bottom cushion.The height at heavy each position of door frame can be adjusted by adjustable bracket, thus ensure that it in the same horizontal line.
Therefore, the utility model, by increasing the lumps of wood in supporting mechanism, ensure that whole supporting mechanism has resiliency, prevents it to be out of shape, and the intensity of whole supporting mechanism is comparatively strong, can carry out inching, prevent the generation of security incident, simple and reasonable for structure.
