Water-containing region anchor cable or anchor rod hole sealing method, hole sealing agent and stirrer

Abstract

An embodiment of the invention discloses a water-containing region anchor cable or anchor rod hole sealing method, a hole sealing agent and a stirrer, and relates to the field of underground engineering supporting. Water-containing region anchor rod or anchor cable drilled holes are blocked. The method comprises the following steps: sleeving an anchor cable or anchor rod exposed head with a prefabricated tubular-column-shaped hole sealing agent, and pushing the prefabricated tubular-column-shaped hole sealing agent into an anchor rod or anchor cable drilled hole; aligning the hollow portion ofa U-shaped rod jaw of the stirrer to an anchor rod or anchor cable for positioning, and forwards pushing the U-shaped rod jaw into the hole sealing agent until the bottom of the U-shaped rod jaw is in contact with the anchor rod or anchor cable exposed head; rotating the stirrer, piercing the outer skin of the hole sealing agent through the U-shaped rod jaw, and stirring a hole sealing chemical agent; and after the hole sealing chemical agent is stirred and mixed uniformly, drawing out the U-shaped rod jaw of the stirrer, standing for a preset time until the hole sealing chemical agent is solidified and expanded, and then sealing an anchor rod or anchor cable hole. The water-containing region anchor cable or anchor rod hole sealing method is suitable for underground engineering supportingconstruction for coal mine laneways, tunnels or channels beside subways and the like.

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 an anchor cable or bolt hole in a water-bearing area, a sealing agent and a mixer. Background technique [0002] As an effective way of supporting and strengthening roadways and slopes, anchor cables and bolts have been widely used in geotechnical engineering, mining, subway tunnel construction and other related fields. During the construction of anchor cables or anchor rods, it is necessary to drill holes to anchor the anchor cables or anchor rods in the boreholes. At present, anchoring agents are generally installed at the bottom of the anchor cables or anchor rods, and pallets are installed at the exposed ends. Fasteners fix the anchor cable or bolt in the borehole. The commonly used sealing methods are mainly: grouting and sealing. However, the existing sealing scheme is generally used...

AI Technical Summary

Problems solved by technology

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
