Alignment automatic measurement system and method for segmental construction of concrete continuous beam bridge

Abstract

The invention provides a line shape automatic measurement system and method for concrete continuous beam bridge section construction. A static force level base station is arranged at the top of a pier of a bridge, and a static force level measuring point is arranged on a bottom die suspended below a hanging basket of the bridge; the static force level measuring point is connected with the static force level base station through a liquid pipe, a gas pipe and a data transmission line; the static force level measuring point is wirelessly connected with a cloud end. Therefore, the line shape automatic measurement system for the concrete continuous beam bridge section construction can be realized; elevation data of all constructed sections of a bridge structure are provided; the problem that except for the line shape of the current section under construction, the line shapes of other sections cannot be effectively measured in a construction process is solved; the automatic measurement system is easy to mount and high in precision, and nearly no manual intervention is needed.

Description

technical field [0001] The invention relates to an automatic linear measurement system and method for segmental construction of a concrete continuous beam bridge. Background technique [0002] Long-span prestressed concrete bridges are limited by span and construction period, and the hanging basket segmental cantilever pouring method is often used for construction. The construction control work mainly monitors the alignment and internal stress of the bridge. Among them, the bridge alignment control is mainly based on manual methods, and the alignment of the completed beam section cannot be effectively monitored. When the bridge span is large, the bottom alignment of the beam is prone to problems such as broken lines and corners. [0003] In the monitoring work, the alignment of each completed section of the bridge at each construction stage can be calculated through finite element simulation, but due to the above-mentioned monitoring reasons, the measured values ​​are missin...
