A bridge construction deformation monitoring device

Abstract

The invention discloses a bridge construction deformation monitoring device, which belongs to the technical field of bridge construction and includes a detection device, a laser monitoring device, an upper support platform, a lower support platform, an adjustment mechanism, a liquid level control mechanism, a lifting mechanism, a laser detection mechanism and a laser Alignment body. The present invention provides a bridge construction deformation monitoring device, selects a plurality of datum planes, detects the change of the detection device to which each datum plane belongs through laser alignment, selects the datum plane with the smallest variation range, and divides the datum planes into There are multiple areas, and a liquid level control mechanism is buried in each area. Through the principle of liquid communication, the liquid level control mechanism pushes the monitoring equipment to adjust its position accordingly when multiple areas change, so that the monitoring equipment maintains a state with the smallest change. The monitoring equipment passes Automatic straightening by gravity straightening method and laser alignment method make it easier to install between multiple devices and avoid excessive errors.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a bridge construction deformation monitoring device. Background technique [0002] With the rapid development of my country's transportation industry, more and more long-span bridges are being built and planned. In order to ensure the safety of bridge structure construction, achieve the design goals of bridge completion, and improve construction quality, bridge construction monitoring has become a An important part of bridge construction technology. [0003] During the bridge construction process, in order to ensure the safety of the bridge, it is necessary to monitor the deformation of the bridge. The existing deformation monitoring methods mostly use external equipment for laser positioning, target measurement and other monitoring deformation methods. In the process of deformation monitoring, it is necessary to establish monitoring equipment benchmarks Detection poi...

Problems solved by technology

[0005] The purpose of the present invention is to provide a bridge construction deformation monitoring device to solve the problem that the benchmark detection point where the monitoring equipment is located and the equipment will be subject to slight changes due to environmental influences, which will have a certain impact on the accuracy of the data measured by the equipment and easily mislead the monitoring Personnel need to be manually calibrated frequently to ensure its accuracy, which brings a certain burden to the monitoring personnel. At the same time, the construction process of multiple equipment is easily affected by the construction technology of the installation workers, which may easily lead to different benchmark errors between equipment, which will eventually affect the accuracy of monitoring. technical problems that endanger the normal construction of bridges
