Tunnel groove forming die trolley

Abstract

The invention provides a tunnel groove forming die trolley. The tunnel groove forming die trolley comprises a body stretching across the two sides of a tunnel, wherein groove dies and groove baffles positioned between the groove dies and the body are fixed to the two sides of the body in an outward suspension manner correspondingly; the vertical height of each groove die and the vertical height ofeach groove baffle can be independently adjusted; the relative distance between the groove die and the body and the relative distance between the groove baffle and the body can be integrally adjusted; the groove die and the groove baffle are positioned on the same side; each groove die comprises a die body used for forming the internal structure of a groove and square pipes arranged on the two sides of the upper surface of the die body in the length direction; and the square pipes can move along the upper surface of the body to stretch out of the die body in a suspension manner or contract into the die body. The tunnel groove forming die trolley has the beneficial effects that the height of each groove die and the height of each groove baffle and the distance between the groove die and the center of the tunnel are independently adjusted, the square pipes used for forming cover plate steps contract, and therefore corner angle damage during die releasing is prevented.

Description

technical field [0001] The invention relates to the technical field of tunnel construction equipment, in particular to a tunnel groove forming mold trolley. Background technique [0002] After the construction of the invert layer and the filling layer of the tunnel pavement, it is necessary to construct a water trench cable trench inside the tunnel side wall. In order to facilitate the control of the height and position of the trench on both sides of the tunnel without affecting the normal operation in the tunnel, the existing technology Generally, a mold trolley is used and groove molds are fixed on both sides. However, there are turns and unequal heights in the tunnel. At this time, the positions of the groove molds on both sides need to be adjusted. In the prior art, the mold trolley needs to be moved longitudinally along the tunnel to adjust the position of the groove molds on both sides relative to the center of the tunnel. It is very inconvenient to move the heavy mol...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a mold trolley that prevents the groove edges from being damaged, and can conveniently adjust the relative height and distance of the groove molds on both sides; The groove is easily damaged and the mold trolley is inconvenient to adjust the height and distance of the mold
