Benefits of technology

This patented technology provides technical benefits that include simplifying the production process by making it easier or more efficient than existing methods while maintaining accuracy during the gunshot concrete operations. Additionally, there's provided a safer way to detect if any cracks occur inside the walls made up of two layers - one layer being reinforced against another wall called the backliner.

Problems solved by technology

Technological Problem addressed during this patents describes how difficult it can happen with traditional techniques like drilling or jackhammer excavations on high altitude areas where there may exist rocks that could cause damage if they shouldn't penetrate through these layers. This problem arises because existing anchors cannot effectively reinforce certain types of materials without causing harm themselves over time due to their unique characteristics.

Abstract

The invention belongs to the technical field of tunnel safety detection, and relates to a gas tunnel system anchor rod and an anchor rod detection safety construction method. The gas tunnel system anchor rod is installed in tunnel primary support sprayed concrete, and the tunnel primary support sprayed concrete comprises primary sprayed concrete and secondary sprayed concrete. The gas tunnel system anchor rod comprises an anchor rod body, one end of the anchor rod is provided with a lathe thread, and the end, close to the lathe thread, of the outer side of the anchor rod is sleeved with a casing pipe; a hollow hole channel is formed between the casting pipe and the anchor rod; and one end of the casing pipe and the lathe thread end of the anchor rod are provided with a plastic cap in a matched mode. The gas tunnel system anchor rod further comprises a sleeve connected with the lathe thread end of the anchor rod, the sleeve is internally provided with an internal thread matched with thelathe thread, and the end, away from the anchor rod, of the sleeve is provided with a standard part for detection in a matched mode. According to the gas tunnel system anchor rod, the surface of theprimary sprayed concrete is in mechanical connection with the long anchor rod, through the detection method, the anchor rod detection requirements can be met, in addition, the no-flame operation requirement for the interior of a gas tunnel can be met, and the construction safety requirement of the gas tunnel is met.
