Description

Corridor trolley in immersed tube tunnel Technical Field The application relates to the field of immersed tube prefabrication construction, in particular to a gallery trolley in an immersed tube tunnel. Background Prefabricated immersed tube tunnels have found increasingly widespread use in recent years as an important traffic channel across water areas such as rivers, straits, and the like. The tunnel form not only can effectively solve the problem that traffic spans across a water area, but also has the advantages of small influence on surrounding environment, relatively short construction period and the like. With the continuous advancement of infrastructure construction, there is an increasing demand for prefabricated immersed tube tunnels, which are of increasing importance in traffic networks. The immersed tube is generally provided with two driving channels, and a middle corridor is arranged between the two driving channels, wherein the construction quality and efficiency of the middle corridor directly influence the construction progress and the service performance of the whole immersed tube tunnel. In gallery construction in a prefabricated immersed tube tunnel, conventionally, two modes of a wood template and a steel template are often adopted for concrete pouring molding. The wood form is typically formed by splicing boards, which are secured to a pre-built support frame by nails or bolts to form the form structure. The steel templates are welded or assembled into specific shapes by adopting steel plates, and are mounted on the supporting structure by utilizing special clamps and connecting pieces, so that the forming support of the centering gallery concrete is realized. These methods meet to some extent the basic requirements of the construction of the middle corridor, but also have respective characteristics and limitations. However, these prior template assemblies suffer from a number of significant drawbacks. The wooden template is easy to be damped and deformed, so that the template structure is unstable, the molding precision of the post-pouring strip is difficult to ensure, and the construction quality of the middle corridor is further influenced. The steel template is high in strength, but heavy in weight, and the installation and disassembly processes are complicated, so that the construction difficulty and the construction time cost are increased, and the construction efficiency is not improved. Disclosure of Invention In order to reduce construction difficulty and time cost, the application provides a gallery trolley in a immersed tube tunnel. The gallery trolley in the immersed tube tunnel provided by the application adopts the following technical scheme: The gallery trolley in the immersed tube tunnel comprises an inner support frame and two inner side templates, wherein the two inner side templates are respectively arranged at two sides of the inner support frame, the top parts of the two inner side templates are respectively provided with a top plate structure, the top plate structures horizontally extend to the upper part of the top part of the inner support frame, the top part of the inner support frame is provided with two groups of translation driving parts, the two groups of translation driving parts are in one-to-one correspondence with the two inner side templates, and the translation driving parts are used for driving the corresponding inner side templates to approach or separate from the inner support frame in the direction of the inner support frame; When the middle gallery is constructed, the jacking driving piece drives the inner supporting frame to ascend, and simultaneously drives the top plate structure at the top of the inner side template to be in position at the construction position of the top of the middle gallery, and the translation driving piece drives the inner side template to move in the direction away from the inner supporting frame so as to be in position at the construction positions at the two sides of the middle gallery, so that the upper inner side template is driven to be outwards unfolded and abutted to the inner wall of the adjacent immersed tube section; when the middle corridor is constructed, a plugging strip is arranged between the construction gaps, and the two top plate structures at the top and the plugging strip form an inner top template for middle corridor pouring construction, and form an inner mold structure for middle corridor pouring construction together with the inner template; When demoulding, the translation driving piece drives the inner side template to move towards the direction of the inner side supporting frame so as to finish demoulding operation of the inner side template position, and the jacking driving piece drives the inner supporting frame to move downwards and drives the inner side template and the top plate structure to move downwards integrally so as to finish demoulding operation of the inner top template positio
