Abstract
A piston type tunnel walling template and a method for utilizing same to build a tunnel wall body are provided. The piston type tunnel walling template comprises a template framework, a piston plate and rack, wherein the piston plate is formed by an upper piston plate and a lower piston plate; the upper piston plate and the lower piston plate are rotationally connected via a pin roll; the lower piston plate is further provided with a jack (III); and a telescopic end of the jack (III) is fixed on the upper piston plate. A movable piston plate is added to a traditional tunnel walling template structure, so bearing capacity is strengthened after fillers are solidified and high compressive strength can be achieved; on the other hand, when the walling template is demolded and moves forward, the jack on the piston plate can fully stretch, so the fillers can be quickly demolded and the whole walling construction efficiency can be improved; original matchable vibrating equipment and pressing equipment can be avoided with the improved walling template, so simple construction technology can be achieved; and strong operability and adaptation can be realized and the piston type tunnel walling template is worthy of promotion in the industry.
