Problems solved by technology

[0002] The current observation method for the surface displacement of the surrounding rock of the roadway is to lay out measuring points on the two sides of the roadway and the roof and floor, that is, to fix iron hooks at the ends of the anchor rods or nail in spikes and sharp wooden piles, and the technicians use tools such as box rulers to measure manually. It is very time-consuming and labor-intensive to obtain the displacement and deformation data of the roadway roof, floor and two side panels, and errors are prone to occur in single-person measurement

Abstract

The invention discloses a roadway side displacement observation device which comprises a fixed tray, a cylindrical pipe arranged on one side of the fixed tray and a measuring rope matched with the fixed tray and the cylindrical pipe. A through hole communicated with the inner cavity of the cylindrical pipe is formed in the fixed tray; one end of the cylindrical pipe is fixedly connected with the fixed tray, and a conical pipe is arranged at the other end of the cylindrical pipe; two ends of the conical pipe are opened, and the conical pipe sleeves the cylindrical pipe; the measuring rope is arranged in the cylindrical pipe; one end of the measuring rope penetrates through the through hole to extend to the outer side of the fixed tray, and the other end penetrates through the opening of the conical pipe to extend to the outer side of the cylindrical pipe and is provided with an anchor hook. The device is simple in structure, convenient to operate, low in cost, capable of accurately displaying roadway surface displacement data, convenient for technicians to observe and record, capable of being operated by one person, and time-saving and labor-saving.

Description

technical field [0001] The invention relates to the technical field of underground engineering surrounding rock monitoring, in particular to a roadside displacement observation device. Background technique [0002] The current observation method for the surface displacement of the surrounding rock of the roadway is to lay out measuring points on the two sides of the roadway and the roof and floor, that is, to fix iron hooks at the ends of the anchor rods or nail in spikes and sharp wooden piles, and the technicians use tools such as box rulers to measure manually. It is very time-consuming and labor-intensive to obtain the displacement and deformation data of the roadway roof, floor and two side panels, and errors are prone to occur in single-person measurement. Therefore, the technical problem of the above reaction is a problem to be solved urgently by those skilled in the art. Contents of the invention [0003] The technical problem to be solved by the present invention...
