Abstract
The utility model belongs to the technical field of mining area pressure monitoring equipment, and relates to positioning nuts for convergence deformation monitoring of surrounding rock of a roadway, which are designed for solving the problem about difficulty in positioning in convergence deformation monitoring of a coal mine tunnel. Each positioning nut mainly comprises an anchor rod nut and a metal column ring; the anchor rod nuts are changed along with diameter change of an anchor rod for roadway support; the metal column rings are welded on the anchor rod nuts. The positioning nuts are simple in structure, low in cost, convenient to process, manufacture and mount, and strong in engineering practicability.
Description
Technical field
The utility model belongs to the mine pressure monitoring equipment technical field, is specifically related to a kind of monitoring point positioning device, relates in particular to roadway surrounding rock convergent deformation Monitoring and Positioning nut.
Background technique
The monitoring of roadway surrounding rock convergent deformation is the important content of strata behavior analysis of roadway observation, 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 to the convergent deformation monitoring is a very important job.Can disclose intuitively stability state and the supporting effect of tunnel country rock in tunneling process 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 relation of driving time, thereby for the development of deformation trend in prediction tunnel later stage with optimize design of its support foundation is provided.
Carry out roadway surrounding rock convergent deformation when monitoring, generally at the top board and two in tunnel, help to arrange measuring point, to measure the relative deformation of point-to-point transmission, the relative deformation as relatively the shifting near of roof and floor, two between helping 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, adopting more and make peg in roadway surrounding rock, be coated with the methods such as red paint at present on anchor rod pallet board, but these methods all can accurately not carried out the measuring point location, especially in the actual measurement process, each measuring point is difficult to accomplish that unanimously measurement error is larger, therefore, need a kind of new roadway surrounding rock convergent deformation monitoring and positioning device of model utility, accurately to locate measuring point.
Summary of the invention
The purpose of this utility model 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.
Technical solution adopted in the utility model is: roadway surrounding rock convergent deformation Monitoring and Positioning nut, and it mainly is comprised of anchor nut and the metal band of column; The different variation of bolt diameter that described anchor nut is used with roadway support; Described metal column boxing is connected on anchor nut.
Construction using method of the present utility model is: at first determine the monitoring section of roadway surrounding rock convergent deformation monitoring and the exact position of each measuring point, then on corresponding anchor pole, setscrew nut is installed at each point position of determining, and tighten, finally, the two ends of contraction meter are hooked on the metal band of column of two setscrew nuts, are surveyed.
Working principle of the present utility model is: roadway surrounding rock convergent deformation Monitoring and Positioning nut is arranged on tunnel supporting anchor rod, not only easy for installation, and position is fixed, during each enforcement monitoring, 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 beneficial effects of the utility model are: 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, greatly reduces measurement error.
