Problems solved by technology

[0003] The purpose of the present invention is to provide a garbage classification management system for tracking floating population with big data, so as to solve the problem of the lack of easy-to-determined positioning points in the construction of box girders in the prior art, and the lack of support of corrugated steel webs during the positioning process. Influenced by wind and other factors, long positioning time and poor positioning accuracy

Abstract

The invention discloses a corrugated steel web positioning method and an adopted bidirectional adjusting and positioning device. The corrugated steel web positioning method comprises the following steps of S1, mounting the bidirectional adjusting and positioning device of a corrugated steel web at a fixed end die; S2, obliquely hoisting the corrugated steel web into the die according to a designedslope; S3, adjusting and positioning the corrugated steel web at the fixed end die side in height direction and transverse direction of a bridge; and S4, adjusting and positioning the corrugated steel web 1 at a matched beam side opposite to the fixed end die side in height direction and transverse direction of the bridge. The corrugated steel web positioning method is convenient and quick to position, can reduce influence of external factors such as wind power and is more accurate and reliable to position.

Description

technical field [0001] The invention belongs to the field of bridges, and in particular relates to a corrugated steel web positioning method and a bidirectional adjustment and positioning device adopted. Background technique [0002] At present, corrugated steel webs are widely used in box bridges. The corrugated steel webs not only greatly reduce the weight of the bridge, but also ensure the structural strength of the bridge. In the construction process of the corrugated steel web in the prior art, the molds including the fixed end mold, the movable end mold, the bottom mold, the side mold and the inner mold are assembled first, and then the corrugated steel web is hoisted. There are some construction methods when positioning Two chain hoists are arranged at the front and rear ends of the corrugated steel web. One end of the chain hoist is connected to the hanging basket hanger, and the other end is connected to the steel web; Horizontal and vertical positioning. At the s...
