Technical Field
The utility model belongs to the technical field of the railway construction auxiliary facilities, especially, relate to a real-time measuring device that rectifies is advanced on superelevation frame bridge top.
Background
With the rapid development of economic construction in China, the existing traffic facilities cannot meet the use requirements, so that a plurality of projects for passing the existing railway under the frame bridge appear. In order to reduce the influence of construction on the existing railway train operation and transportation, the frame bridges are generally constructed by adopting a jacking method. The construction by adopting the jacking method has the characteristics of less investment, short construction period, short time for influencing the existing railway operation and the like, but the construction difficulty is different under the influence of geological conditions, the structural size of the frame bridge and the like in the jacking construction process of the frame bridge.
For the jacking construction of the frame bridge with high grade of crossing lines, busy trains and ultrahigh bridge body height, the jacking construction process is extremely difficult to control, and in order to ensure that the frame bridge can be positioned in place with high precision, the jacking posture of the frame bridge must be measured in real time in the jacking process, so that higher requirements are provided for the measurement work in the jacking process.
The traditional real-time measurement method in the jacking process of the frame bridge is that a scale is respectively fixed on the inner walls of two sides of a foundation pit of the frame bridge, two measurement personnel read and report in real time according to the scale and report data to a commander by using an interphone, and once the commander finds that the data of the two sides exceed a preset value, the construction personnel are immediately organized to correct the deviation. However, this method has three disadvantages:
1. the reporting by using the interphone is delayed to a certain degree, so that the data reported by two measuring personnel are not synchronized in real time actually;
2. due to the reasons of human eye parallax error of measuring personnel, scale setting error and the like, reported data may have errors, and particularly the reported data is serious in night construction;
3. because the both sides of frame bridge can constantly take place the soil stone and slump in the jacking in-process, consequently have certain threat to survey crew's personal safety.
Particularly, under the condition that two frame bridges are opposite to each other, if the height difference of the two frame bridges is large and the construction period is tight, the two frame bridges need to be simultaneously jacked, and at the moment, the jacking posture control difficulty of the frame bridge is higher.
