Embodiment Construction

[0032] It should be noted that the embodiments in the present application and the features of the embodiments may be combined with each other in the case of no conflict. The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0033] like figure 1 and image 3 As shown, the box culvert mold of the shield tunnel in this embodiment includes: a mold body 10 , a base 40 , a guide rail structure 50 and a driving mechanism 110 , wherein the mold body 10 includes a bottom mold 20 and two inside and outside the bottom mold 20 . The side mold 30 on the side, the side mold 30 includes a mold closing position and a mold opening position. When the side mold 30 is in the mold closing position, the bottom mold 20 and the side mold 30 enclose the casting cavity 1, and the side mold 30 is located at the mold opening position. In the case of position, the side mold 30 is far away from the bottom mold 20; th...

Abstract

The invention provides a box culvert mold for a shield tunnel, comprising: a mold body, a bottom mold and side molds located on the inner and outer sides of the bottom mold, the side molds include a mold closing position and a mold opening position, and the side mold is located at the closing position. In the case of the mold position, the bottom mold and the side mold form a pouring cavity. When the side mold is in the mold opening position, the side mold is far away from the bottom mold; the base is set on the inner and outer sides of the bottom mold; the guide rail structure is set in On the base and / or the bottom mold, the side mold can slide on the guide rail structure; the driving mechanism drives the side mold to move between the mold closing position and the mold opening position. The application of the technical solution of the present invention can effectively solve the problem of difficulty in assembling and disassembling the box culvert mold in the prior art.

Description

technical field [0001] The invention relates to the field of box culvert processing, in particular to a box culvert mold for shield tunnels. Background technique [0002] The large box culvert is the main component of the super-diameter shield tunnel project. It is installed below the center of the forming tunnel and is the main bearing component of the road surface. The box culvert is made by prefabrication, that is, pouring concrete into the box culvert mould. [0003] Nowadays, most of the box culvert mold structures are manually assembled. The box culvert mold is composed of multiple independent components such as the bottom mold and the inner and outer templates. When assembling the box culvert mold, each template is manually lifted to the bottom mold with a crane, and then bolts are used to hoist each template to the bottom mold. Lock each template to form a box culvert mold. After the pouring is completed, the template of the mold is also manually removed, and each ...
