The device installation is convenient, can be according to the change of tunnel section size and adjusting device's offset.
In order to solve the technical problem, the utility model discloses the technical scheme who takes does:
a tunnel adjustable support distance self-stabilizing inverted arch steel end mold comprises a bottom mold and a top mold, wherein the top mold is arranged right above the bottom mold, self-stabilization is realized through the weight of a template, the bottom mold comprises a first bottom mold, a second bottom mold and a bottom mold adjusting block, and the bottom mold adjusting block is positioned between the first bottom mold and the second bottom mold; the top die comprises a first top die, a second top die and a top die adjusting block, the top die adjusting block is located between the first top die and the second top die, and self-stabilization is carried out between the die plates through self-weight of the die plates.
The bottom die adjusting block and the top die adjusting block are replaceable templates.
The top die and the bottom die are both formed by welding steel plates, and the cross section of the top die and the bottom die is of a box-shaped structure.
And a first water stop is arranged between the bottom die and the top die, a second water stop is arranged below the bottom die, and one half of the water stop is positioned in the inverted arch concrete.
The first water stop adopts a middle-buried water stop, and the second water stop adopts a back-to-back water stop.
Compared with the prior art, the utility model discloses the beneficial effect who has does:
the installation progress of the template is accelerated, the size of a single template is large, the template does not need to be connected and reinforced, and the installation progress is greatly improved compared with the efficiency of a combined template. The setting of adjusting block makes the device can adjust the offset according to actual need, and easy operation is swift, reduces constructor's work load.
