Bridge deck construction monitoring method and system

Abstract

The present application discloses a bridge deck construction monitoring method and system, the system includes a data processing unit and at least one bridge deck monitoring unit; the data processing unit is used to determine the following The extension direction of each section on the first bridge surface during the process of building the first bridge deck from the first bridge pier as the starting point to the second bridge pier, and the process of building the second bridge deck from the second bridge pier to the first bridge pier Each interval segment on the second bridge surface corresponds to the extension direction; each interval segment is provided with at least one bridge deck monitoring unit along the extension direction, and each bridge deck monitoring unit includes a first light transmitter and a first light receiver, The first optical transmitter transmits an optical signal to the extension direction corresponding to the section where it is located; the data processing unit is also used to determine whether each section deviates from the The corresponding extension direction and the corresponding deviation amount.

Description

technical field [0001] The present application relates to the technical field of intelligent monitoring, in particular to a bridge deck construction monitoring method and system. Background technique [0002] With the vigorous development of bridges, high-speed railways, roads and other infrastructure projects, it is necessary to build more large bridges with continuous girders, that is, to continuously lay bridge decks between multiple bridge piers. In order to speed up the progress of the project, the bridge decks were constructed from two adjacent piers, and finally the bridge decks on both sides merged together. During this process, the offset direction of the bridge decks on both sides was measured during construction to ensure the smooth convergence of the bridge decks on both sides. At present, the offset direction of the bridge deck can only be measured manually by the level gauge. It is necessary to suspend the construction after each small section of the bridge dec...

AI Technical Summary

Problems solved by technology

At present, the offset direction of the bridge deck can only be measured manually by the level gauge. It is necessary to suspend the construction after each small section of the bridge deck is built, transport the level gauge to the bridge deck, and manually measure the horizontal and vertical directions of the bridge deck. The method has low precision, complicated operation and unsafe
