Hole sealing method for anchor cable or bolt hole in water-bearing area, sealing agent and agitator

Abstract

The embodiment of the invention discloses a hole sealing method, a sealing agent and an agitator for an anchor cable or an anchor hole in a water-bearing area, and relates to the field of underground engineering support, which can facilitate the plugging of the anchor rod or anchor cable drilling in the water-bearing area. The method includes: putting the prefabricated pipe-column sealing agent on the anchor cable or the outcrop of the anchor rod, and pushing it into the drill hole of the anchor rod or the anchor cable; The anchor cable is positioned, and the U-shaped fork rod is pushed forward to insert the sealing agent until the bottom of the U-shaped fork rod contacts the anchor rod or the outcrop of the anchor cable and stops; The outer skin of the pore agent is punctured, and the pore sealing agent is stirred; after the pore sealing agent is stirred and mixed evenly, the U-shaped fork rod of the agitator is drawn out, and it is left to stand for a predetermined period of time, and the pore sealing agent solidifies and expands. Close the anchor rod or anchor cable hole. The invention is applicable to underground engineering support construction such as mine roadways, tunnels or subway side passages.

Description

technical field [0001] The invention relates to the technical field of underground engineering support such as mines, tunnels and subway side passages, and in particular to a method for sealing anchor cables or bolt holes in water-bearing areas, a sealing agent and an agitator. Background technique [0002] As an effective support and reinforcement method for roadways and slopes, anchor cables and bolts have been widely used in related fields such as geotechnical engineering, mining, and subway tunnel construction. During the construction of anchor cable or anchor rod support, it is necessary to drill holes to anchor the anchor cable or anchor rod in the drill hole. At present, anchoring agent is generally installed at the bottom of the anchor cable or anchor rod, and a tray is provided at the exposed end. Fasteners fix the anchor cable or anchor rod in the drilling hollow. The commonly used sealing methods mainly include: grouting and sealing. However, the existing sealing ...

During the construction of anchor cable or anchor rod support, it is necessary to drill holes to anchor the anchor cable or anchor rod in the drill hole. At present, anchoring agent is generally installed at the bottom of the anchor cable or anchor rod, and a tray is provided at the exposed end. Fasteners fix the anchor cable or anchor rod in the drilling hollow. The commonly used sealing methods mainly include: grouting and sealing. However, the existing sealing scheme is generally used for sealing the upper and bottom of the drilling hollow, and is Closure of clear holes not inserted with anchor cables or rods

There is currently no plan to seal the shallow part of the borehole with anchor cables or bolts to the orifice
