Axial force exerting construction method for automatic servo steel brace system
The invention relates to an axial force exerting construction method for an automatic servo steel supporting system. The method comprises the following steps: firstly, pre axial force is exerted on a steel brace; secondly, initial axial force is exerted on the steel brace; thirdly, complex axial force is exerted on the steel brace. Compared with a traditional axial force exerting mode of an underground automatic servo system steel brace, the axial force exerting of the traditional automatic servo system steel brace is one-time exerting. The characteristic that the axial force of the automatic servo system steel brace can be changed at anytime is utilized, according to different construction conditions, different cutting depth, and different formation of the supporting system, the axial force is exerted appropriately and gradually, so that the characteristic and the advantage of the automatic servo system steel brace are maximized, and therefore, the safety of ground walls and peripheral protective buildings can be controlled.
