Sprayed concrete supporting structure detection equipment

Abstract

The invention discloses sprayed concrete supporting structure detection equipment. The detection equipment comprises a left supporting pile, and a right supporting pile is arranged on one side of theleft supporting pile; a lower ruler is arranged on the side, close to the right supporting pile, of the left supporting pile; and an upper ruler is arranged on the side, close to the left supporting pile, of the right supporting pile. The base is fixedly connected with the lower scaleplate through a clamping device, the right supporting pile is fixedly connected with the upper scaleplate through aclamping device, the lower scaleplate is connected with the upper scaleplate through a lantern ring, observation windows are formed in the lower scaleplate and the upper scaleplate, and the base is arranged in the lower scaleplate and the upper scaleplate and corresponds to the observation windows in position. The supporting device is additionally arranged between the upper scale and the lower scale of original sprayed concrete supporting structure detection equipment and the ground, and the situation that the suspended ends of the upper scale and the lower scale are connected only through the lantern ring, consequently, dislocation occurs between the upper scale and the lower scale, data errors are caused, and the detection result is affected is avoided.

Description

technical field [0001] The invention belongs to the technical field of supervision and detection, and in particular relates to a detection device for a shotcrete support structure. Background technique [0002] Support is the general term for the components or other measures taken to support, strengthen or cover the surrounding rock for the stability and construction safety of the underground chamber after excavation. When the traditional mining method is used for construction, there are three types of support: retaining pillars, erecting supports, and strengthening rocks. When the new Austrian method is used for construction, it can be divided into two types: temporary support and permanent support according to the support effect, including spray anchor support, steel and wood support, concrete lining, grouting support and other types. [0003] The prior art has the following problems: 1. The existing shotcrete support structure detection equipment has a lower scale and an...

Problems solved by technology

[0003] The prior art has the following problems: 1. The existing shotcrete support structure detection equipment has a lower scale and an upper scale respectively fixed on the left and right support piles, and the cracking of the support piles is detected by comparing the data on the upper scale However, the other end of the upper scale and the lower scale is connected by a collar, which may easily cause the dislocation of the upper scale and the lower scale, resulting in data errors and affecting the detection structure; Fix the upper scale and the lower scale to the right support pile and the left support pile respectively, but the size of the clamping device is fixed, so it can only be used to detect the cracking degree of a support pile of a single size, resulting in a small equipment use area
