Abstract

The invention provides a box culvert mold of a shield tunnel. The box culvert mold of the shield tunnel comprises a mold body, bases, a guide rail structure and a driving mechanism; the mold body comprises a bottom mold and side molds, the side molds are located on the inner and outer sides of the bottom mold, the side molds comprise mold closing positions and mold opening positions, under the condition that the side molds are located at the mold closing positions, a pouring cavity is defined by the bottom mold and the side molds, under the condition that the side molds are located at the moldopening positions, the side molds are away from the bottom mold; the bases are arranged on the inner side and the outer side of the bottom mold; the guide rail structure is arranged on the bases and / or the bottom mold, the side molds can slide on the guide rail structure; and the driving mechanism drives the side molds to move between the mold closing positions and the mold opening positions. Byapplying the technical scheme of the box culvert mold of the shield tunnel, the problem that in the prior art, the box culvert mold is difficult to assemble and disassemble can be effectively solved.

Description

technical field [0001] The invention relates to the field of box culvert processing, in particular to a box culvert mold for a shield tunnel. Background technique [0002] The large box culvert is the main component of the super-large diameter shield tunneling project. It is installed in the middle and lower part of the forming tunnel and is the main bearing component of the road surface. The box culvert is made by prefabrication, that is, the concrete is poured into the box culvert mold and formed. [0003] Nowadays, most of the box culvert mold structure adopts manual assembly. The box culvert mold is composed of multiple independent components such as the bottom mold and the inner and outer formwork. Lock each formwork to form a box culvert mold. After the pouring is completed, the formwork of the mold is also manually removed, and each formwork is hoisted to a suitable position by a crane one by one. This method of assembling and disassembling the box culvert moulds h...
