Adhesion hinged type segmented prefabricated assembled arch bridge and intelligent construction control method

Abstract

The invention discloses an adhesion hinged type segmented prefabricated assembled arch bridge and an intelligent construction control method. The number of arch seats is two; a sliding inclined surface is formed on the mounting side of each arch seat; the plurality of section arch rings are arranged in parallel; the two ends of each section arch ring are attached to two sliding inclined surfaces correspondingly and are fixed in a pouring mode; each section arch ring comprises a plurality of sections of prefabricated wedge blocks; adhesive layers are formed on the top surfaces of the multiple sections of prefabricated wedge blocks; each adhesive layer consists of a polymer adhesive and a reinforcer; the multiple sections of prefabricated wedge blocks are connected in series through the adhesive layers, and every two adjacent prefabricated wedge blocks form a movable connection structure. During construction, by collecting sensor monitoring data, according to an established arch bridge digital twinborn model and an on-arch construction load numerical simulation calculation result, the prefabricated arch rings are tensioned in a graded and segmented mode through intelligent numerical control tensioning equipment according to the on-arch construction load, the linear shape and the internal force of the prefabricated arch rings are adjusted to be consistent with design, and the problem that the bridge forming line shape does not match the designed line shape is solved.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, in particular to an adhesive hinged segmental prefabricated assembled arch bridge and an intelligent construction control method. Background technique [0002] Stone arch bridges are widely used in small and medium span bridges of 5-30 meters because of their convenient materials, simple structure, beautiful shape, good durability and low maintenance cost. But on the other hand, traditional masonry arch bridges need to be erected during construction, and the on-site construction technology requirements are high, often resulting in inaccurate structural alignment control, uneven distribution of material strength, etc., which are more restricted in the field of rapid construction. [0003] Therefore, how to provide an arch bridge structure and construction method that can be easily constructed and in a stable state is an urgent problem to be solved by those skilled in the art.
