Title:
VARIABLE CROSS-SECTION PIPE GALLERY STRUCTURE SUITABLE FOR RAPID CONSTRUCTION AND CONSTRUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/244268
Kind Code:
A1
Abstract:
The present invention relates to a pipe gallery cross-section structure suitable for rapid construction, comprising a top plate, side walls, and a bottom plate. A variable cross-section structure is used for the top plate of which the cross-section height changes gradually. The side walls are provided on two sides of the top plate. A chamfered portion is provided between the side wall and the flat bottom plate. A top mold attached to the top plate is provided below the top plate in the pipe gallery construction. A side mold attached to the side wall is provided below the top mold. A hinge structure is provided between the top mold and the side mold. The present invention also relates to a construction method for the pipe gallery cross-section structure suitable for rapid construction. According to the present invention, the structure of the variable cross-section top plate of which the cross-section height changes gradually can effectively eliminate the stress concentration phenomenon of the pipe gallery under the action of the top and lateral earth pressure and other external loads, and can also fully reduce the weight thereof, save materials, and exert the characteristics of structural force. Accordingly, a curved top mold matching the structure of the variable cross-section top plate is connected to the side mold by means of the hinge structure to form an integral steel inner membrane without bending angles, which is fully suitable for rapid construction of the pipe gallery.
