Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] First, the arch is divided into three sections according to the arch span required by the tunnel, including a main arch section 1 and two auxiliary arch sections. Arch segments are single or concatenated arch segments.

[0023] Such as figure 1 As shown, there is a platform 2 outside the tunnel, and the multiple main arch sections 1 are arranged on the platform 2 according to the arc size and spacing required by the tunnel. Above, make the multiple main arch sections 1 form an integrated structure.

[0024] Such as figure 2 As shown, the arch frame machine 3 includes a chassis 5 and a platform 4, on which a left jib frame 6, a main jib frame 8, and a right jib frame 10 are arranged, and a hoisting mechanism 7 is installed on the left jib frame 6 , The multi-arch clamping tray 15 is housed on the main boom frame 8 . Utilize the hoisting mech...

Abstract

The invention discloses a construction method of tunnel arch rapid installation. The method comprises the steps that an arch is divided into at least two sections according to the arch span needed bya tunnel, one section is the main arch section, the rest sections are auxiliary arch sections, and the main arch section is formed by splicing multiple arch sections outside the tunnel; a multi-trussmain arch section is assembled on a rack outside the tunnel, transverse bars and meshes are welded to the multi-truss main arch section simultaneously, and the multi-truss main arch section forms an integral structure; by means of a hoisting mechanism, the multi-truss main arch section is hoisted to a multi-arch clamping tray of a main arm; an arch machine with the multi-truss main arch section drives in the tunnel and reaches a tunnel face; an arch machine main arm frame lifts the multi-truss main arch section to the mounting position at a time, and an operator stands on the ground or a leftauxiliary arm frame and a right auxiliary arm frame are used for assembling the rest arch sections and the multi-truss main arch section into a whole. Accordingly, by means of the construction process, the construction efficiency can be significantly improved, and labor is saved.

Description

technical field [0001] The invention relates to a method for installing a tunnel arch, in particular to a construction method for quickly installing a tunnel arch. Background technique [0002] In tunnel construction, when the grade of the surrounding rock is poor, arch support is often required to improve the stability of the surrounding rock. [0003] The existing arching machines can only erect one arch at a time, and the arching is basically divided into small sections and transported into the tunnel by loaders or other transport vehicles, and then the short arches are assembled into long arches, and the manipulator of the arching machine Or the hoisting device takes the arch to the manipulator, and then the manipulator clamps the arch and docks in the air. After the splicing of the arch frame is completed, the operator also hangs the steel mesh and welded horizontal bars on the basket of the arch frame machine. Generally speaking, the vertical arch of the existing arc...
