Abstract
The invention relates to an adjusting nut for roadway surrounding rock convergence and deformation monitoring and a using method thereof, and belongs to the technical field of mine ground pressure monitoring devices. The adjusting nut is designed for solving the problem that coal mine roadway convergence and deformation monitoring and adjusting are difficult. The adjusting nut is mainly composed of an anchor rod nut and a metal column ring. The anchor rod nut changes according to different diameters of anchor rods used in roadway supports, and the metal column ring is welded on the anchor rod nut. The adjusting nut is simple in structure, low in cost, convenient to machine, manufacture and install, and strong in project practicability.
Description
Technical field
The invention belongs to mine pressure monitoring equipment technical field, be specifically related to a kind of monitoring point positioning device and using method thereof, relate in particular to roadway surrounding rock convergent deformation Monitoring and Positioning nut and using method thereof.
Background technique
The monitoring of roadway surrounding rock convergent deformation is the important content that observation is pressed in the ore deposit, tunnel, can correctly estimate the stability of roadway surrounding rock by the monitoring of roadway surrounding rock convergent deformation, and then the Best Times section of definite tunnel secondary supporting, and the key position of definite roadway deformation destruction, therefore, roadway surrounding rock being carried out the convergent deformation monitoring is a very important job.Can disclose stability state and the supporting effect of tunnel country rock in tunneling process intuitively by the monitoring of roadway surrounding rock convergent deformation, can also according to the relative displacement variable quantity of analysis on monitoring result roadway surrounding rock, pace of change and with the driving time relation, thereby for the development of deformation trend in prediction tunnel later stage with optimize the supporting design foundation is provided.
Carry out roadway surrounding rock convergent deformation when monitoring, generally help to arrange measuring point at the top board and two in tunnel, measuring the relative deformation of point-to-point transmission, the relative deformation between helping as the shifting near relatively of roof and floor, two etc., surveying instrument employing contraction meter.In roadway surrounding rock convergent deformation observation process, the accurate location of monitoring point is a very difficult problem, many employings are at present made peg, are coated with methods such as red lacquer at the anchor pole pallet in roadway surrounding rock, but these methods all can accurately not carried out the measuring point location, especially each measuring point is difficult to accomplish unanimity in the actual measurement process, and measurement error is bigger, therefore, need a kind of new roadway surrounding rock convergent deformation Monitoring and Positioning measure of invention, with accurate location measuring point.
Summary of the invention
The purpose of this invention is to provide a kind of roadway surrounding rock convergent deformation Monitoring and Positioning nut, this setscrew nut not only can effectively solve the problem of coal mine roadway country rock convergent deformation Monitoring and Positioning difficulty, and simple in structure, with low cost, processing and fabricating and easy for installation, Technological Economy is feasible.
The present invention provides the using method of this setscrew nut simultaneously.
The technical solution used in the present invention is: roadway surrounding rock convergent deformation Monitoring and Positioning nut, and it mainly is made up of anchor nut and the metal band of column; Described anchor nut is with different variation of the used bolt diameter of roadway support; Described metal column boxing is connected on the anchor nut.
Construction using method of the present invention is: at first determine the monitoring section of roadway surrounding rock convergent deformation monitoring and the exact position of each measuring point, at the anchor pole of each point position correspondence of determining setscrew nut is installed then, and tighten, at last, the two ends of contraction meter are hooked on the metal band of column of two setscrew nuts, survey.
Working principle of the present invention is: roadway surrounding rock convergent deformation Monitoring and Positioning nut is installed on the tunnel supporting anchor rod, not only easy for installation, and fixed-site, when each enforcement is monitored, the two ends of contraction meter can be hooked on the metal band of column of two setscrew nuts easily, and accurate positioning, measurement error is little.
The invention has the beneficial effects as follows: roadway surrounding rock convergent deformation Monitoring and Positioning nut structure is simple, processing and fabricating and easy for installation, cost is low, engineering practicability is strong, and can accurately locate measuring point, reduces measurement error greatly.
