Embodiment Construction
[0033] The invention will be further described below in conjunction with the embodiments in the drawings.
[0034] Such as figure 1 As shown, a stepping template for vertical shaft construction based on hydraulic drive of the present invention includes two parts in structure: one is the upper support shoe part, which is realized by extending or retracting the piston rod of the support shoe cylinder 2 1. Move away or move towards each other to realize the tightening of the concrete shaft wall 8 or the separation of the concrete shaft wall 8; the second is the stepping template part, the stepping cylinder 4 piston rod is extended or retracted to drive the template 5 to move downward; at the same time the template 5 is inside The expansion and contraction of the template support cylinder 2 can be used for compression and demoulding during the concrete pouring of the well wall; the alternate action combination of the support shoe cylinder, the stepping cylinder and the support cylinde...
