Description
Technical field
The present invention relates to fields of measurement, the more particularly, to optional centering CPIII measuring methods in railway bed location.
Background technology
It is well known that the optional centering CPIII measurements in railway bed location at present are generally utilized in measurement point cast
One pile foundation and then in pile foundation set the support frame of measuring prism to realize again, but this technology has the following disadvantages：
1st, speed per hour is less than 200km/h railway, and its roadbed location is dug without piling prepressing, therefore on its roadbed
Hole pile anchoring, is easily caused existing line and settles, and then influences traffic safety.
2nd, do not carry out piling prepressing roadbed its embedment stake position it is unstable, easily occur sedimentation and change in displacement so that
Cause measurement data misalignment.
3rd, the stake position method of conventional embedment, long in time limit, cost is big.
4th, for still in the both wired of operation, carrying out, CPIII points are embedded and measurement has more limitations, and security risk is big,
The security risk brought for conventional CPIII measurements is big, and new measuring method can substantially reduce security risk.
The content of the invention
The purpose of the present invention is that there is provided for the optional centering in railway bed location according to above-mentioned the deficiencies in the prior art
CPIII measuring methods, high-precision CPIII measurements are realized in the position needed for measurement point in-site measurement.
The object of the invention is realized and completed by following technical scheme：
One kind is used for the optional centering CPIII measuring methods in railway bed location, it is characterised in that：The measuring method is extremely
Comprise the following steps less：CPIII measurement points injection one at railway bed location scene is embedded to bar, the embedment bar embedment ground
The lower soil body, installs one on the embedment bar top and marks core print；One forced centering foot stool is installed in the mark core print top surface, and by institute
State forced centering foot stool and be adjusted to level；Carried out after measuring prism is installed on the forced centering foot stool using measuring prism
CPIII is measured.
It is to pass through to install a forced centering foot stool in the mark core print top surface, and one is offered in mark core print end face center position
Connecting hole, sets a support bar in forced centering foot stool bottom, support bar is plugged in into what is realized in the connecting hole.
The forced centering foot stool is adjusted into level to refer to, being hinged on the leveling support of the forced centering foot stool to stretch
The leveling bar of contracting, by adjusting leveling support described in the flexible push-and-pull of the leveling bar until level.
The curb underground soil body of the CPIII measurement points at the other end injection scene of the leveling bar.
It is an advantage of the invention that：The site setup on the optional centering CPIII measurement points basis in railway bed location can be achieved；
Simple and reasonable, easy to operate, quick, method is simple, suitable to promote；The present invention can solve existing railway and drive a vehicle frequently, pacify
Full blast nearly big problem, thoroughly solves original CPIII and excavates to cause rail track unstable and then influence traffic safety, duration
The big problem of long, cost.
