Monitoring system for displacement of movable scaffolding system and monitoring method therefor

Abstract

The invention discloses a monitoring system for the displacement of a movable scaffolding system and a monitoring method therefor. The system comprises two guide rails which are arranged in parallel,a monitoring device and a monitoring plate; the movable scaffolding system is arranged on each guide rail, and the monitoring device comprises a laser emitter arranged on one of the movable scaffolding systems; the laser emitter emits a laser light toward the other movable scaffolding system; the monitoring plate is arranged on one of the movable scaffolding systems, and the monitoring plate is used for receiving the laser light emitted by the laser emitter; a marking area and a marking point located in the center of the marking area are arranged on the monitoring plate, and the position of the marking point is arranged at the position where the laser light emitted by the laser emitter falls on the monitoring plate before the two movable scaffolding systems move synchronously. The invention provides the monitoring system for the displacement of the movable scaffolding system and the monitoring method therefor, and judges whether the relative displacement of the two movable scaffoldingsystems exceeds an early warning standard or not by monitoring the position of the laser light on the monitoring plate, so that the practicability is high.

Description

technical field [0001] The invention relates to the field of bridge construction monitoring, in particular to a mobile formwork displacement monitoring system and a monitoring method thereof. Background technique [0002] Mobile formwork is a kind of construction mobile equipment that assists bridge site construction. In the current construction of concrete bridges, the mobile formwork method has the advantages of procedural procedures, easy control of the line shape, short construction period, and no need for foundation work compared with other construction methods. It has many advantages such as processing, wide application range, small construction traffic impact, construction safety, etc., so it has been more and more widely used in the construction of urban viaducts, high-pier highway bridges and sea-crossing bridges. [0003] Whether the mobile formwork can maintain the same speed during the moving process is an important factor affecting the safety of the mobile formw...

AI Technical Summary

Problems solved by technology

[0004] (1) It cannot immediately reflect whether the displacement and settlement of the mobile formwork exceed the early warning standard;

[0005] (2) Affected by the erection position of the total station, measurement cannot be carried out in certain time periods or areas;

[0006] (3) The measurement accuracy is unstable due to the influence of the surrounding environment
