Abstract

The invention relates to a linear control device for a segment prefabricated assembled straight line bridge. The linear control device comprises a first fixing unit, a laser transmitter on the first fixing unit, a second fixing unit, a first perspex sheet on the second fixing unit, the first fixing unit comprises a first fixing plate, a first steel rod and a first round ring, and the second fixingunit is a second perspex sheet. A using method of the linear control device comprises the steps that the laser transmitter is mounted on a cast-in-situ segment of the bridge pier position, the angleof the laser transmitter is adjusted, the first perspex sheet is mounted on a prefabricated segment on the bridge span position, light point coordinates are compared with laser transmitter coordinates, and mounting is completed. According to the linear control device for the segment prefabricated assembled straight line bridge and using method, instruments such as a total station and a level gageare not needed, work of measuring and conversion of six positioning points on the segment is omitted, the construction speed is accelerated, labor workloads of measuring workers are reduced, and the time and labor costs of bridge construction are reduced.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a device and a method for controlling the alignment of a segmental prefabricated linear bridge. Background technique [0002] The segmental girder prefabricated assembly erection construction scheme is a technology applied to bridge construction. Its construction principle is as follows: First, the entire span bridge body is cut along the transverse direction (that is, the direction perpendicular to the longitudinal axis of the bridge), and the bridge is divided into several sections. Segment beam, the top of the pier is the 0# segment beam, and then along the longitudinal axis of the bridge, starting from the 0# segment, the two sides are 1# segment, 2# segment, 3# segment, etc. Among them, the segmental girder of block 0# is cast-in-situ and located at the bridge pier, and the other segmental girders are factory prefabricated and located at the bridge span. Assign ...
