Non-forced centering CPIII measuring method for railroad bed section
The invention relates to the measuring field and in particular to a non-forced centering CPIII measuring method for a railroad bed section. The method is characterized by at least including the following steps that an embedded rod penetrates a CPIII measuring point of a railroad bed section site, the embedded rod is embedded in an underground soil mass of a railroad shoulder, and a core marking head is installed at the top end of the embedded rod; a forced centering stand is installed on the top face of the core marking head and adjusted to be horizontal; and after being installed on the forced centering stand, a measuring prism is used for conducting CPIII measurement. The method has the beneficial effects that a foundation of the non-forced centering CPIII measuring point of the railroad bed section can be arranged on the site; the structure is simple, reasonable and reusable; and the problems that in a conventional railroad CPIII measuring method, a CPIII pile needs to be embedded, the road foundation needs to be evacuated, railway line safety is affected, the pile is not embedded stably, a work period is long, and cost is high are solved, and the non-forced centering CPIII measuring method is suitable for being popularized.
