Large-size mobile base line pile and calibration method thereof

Abstract

The invention relates to a base line pile, and belongs to the field of instrument calibration. The large-size mobile base line pile is characterized by comprising a zero-bit mobile base line pile and a mobile base line target pile, wherein the zero-bit mobile base line pile and the mobile base line target pile are arranged at different points to form a section of base line; the zero-bit mobile base line pile comprises a pile base and four main body brackets arranged on the pile base; a two-dimensional horizontal linear adjusting mechanism, a two-dimensional rotating adjusting mechanism and granite positioning baffle blocks are arranged at the top end of each bracket; the granite positioning baffle blocks are arranged on each two adjusting mechanisms; the mobile base line target pile comprises a base line target pile base and a main body pile frame of a base line target; a horizontal pendulum mechanism is arranged on the main body pile frame of the base line target; and a practice target vertical to a horizontal end surface is arranged on the horizontal pendulum mechanism. According to the base line pile, instant putting, instant calibrating and instant correcting and verifying are achieved by respectively arranging the zero-bit mobile base line pile and the mobile base line target pile which are matched to form the base line; and the problem of a permanent base line field is solved.

Description

technical field [0001] The invention relates to a baseline pile used for calibrating various large-scale engineering measuring instruments, in particular to a large-size mobile baseline pile and an operation method. Background technique [0002] Baseline piles (also known as observation piers) are used as large-scale physical benchmarks and can be used to calibrate various large-scale engineering measuring instruments. However, due to the harsh environmental conditions required for fixed baseline pile foundations, it is necessary to permanently occupy the space of the linear passage for a long time, and After the construction of pile foundation concrete, a certain maintenance period is required. Therefore, not every department has the conditions to establish permanent fixed baseline piles. Moreover, the site requirements suggested in the GB16789-1997 Specific Baseline Measurement Specification and the JJF1214-2008 Length Baseline Calibration Specification on which the perma...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a large-size mobile baseline pile and a verification method, which can be combined and placed to form a baseline, placed in real time, calibrated in real time, and calibrated in real time. The defect that the calibration of low-precision large-scale measuring equipment cannot be carried out due to the baseline site
