The common prestressed anchorage pole that has of current stock, from boring formula stock, end anchor stock etc. and the mode of its bank protection includes: firstly, protecting the slope by using the friction force between an anchor rod and a soil layer; grouting into surrounding rock through an anchor rod, and improving the stability of the side slope to play a role in slope protection; aiming at the two slope protection modes, the utility model provides an anchor rod for protecting a side slope hanging net.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the problems in the prior art and provides an anchor rod for protecting a side slope hanging net.
An anchor rod for protecting a side slope hanging net comprises a drill bit, an anchor rod and a mud jacking rod; a drill bit is arranged at the right side end of the anchor rod; a grout pressing rod is arranged at the left end of the anchor rod; a base plate is arranged at the left end part of the grouting rod; and the right side of the backing plate is provided with an anchor rod head.
According to the anchor rod for protecting the side slope net, the anchor rod is made of the threaded hollow steel; the outer surface of the anchor rod is provided with a drillable thread; grouting holes are uniformly formed in the anchor rods; a baffle plate is arranged at the grouting hole; the baffle plate is lapped above the grouting hole.
According to the anchor rod for protecting the side slope net, the length of the mud jacking rod is 20-40 cm; a sleeve is arranged outside the mud jacking rod; and a grout stopping plug is arranged between the grout pressing rod and the backing plate.
In the anchor rod for protecting the side slope hanging net, the grout stop plug is internally provided with the grout pressing rod; the outer part of the grout stopping plug is extruded with a rubber ring; and a gap between the grout stopping plug and the rubber ring is an air channel.
Foretell side slope is hung net and is protected and use stock, the stock head is provided with the binding.
The utility model has the beneficial effects that:
the anchor rod for protecting the side slope net hanging adopts the threaded hollow steel, can be used for grouting into surrounding rocks through the internal hollow steel, is provided with a grouting hole, during grouting, grout is discharged from a drill bit to the head of the anchor rod, the grouting hole close to the drill bit discharges the grout firstly, under the action of pressure, the separation blade can be lifted upwards, after the grout reaches the designed strength, the separation blade on the anchor rod is in a fish scale shape, the tail part of the separation blade is opened, and the separation blade is meshed with the surrounding rocks, so that the friction force between the anchor rod and the surrounding rocks is increased;
the grout stop plug provided by the utility model has the functions of exhausting and stabilizing pressure, is less in modification of the existing anchor rod and low in modification cost, does not change the original construction process of the anchor rod, can realize the functions of exhausting and stabilizing pressure of grout stop, effectively improves the grouting compactness of an anchor rod hole, and further improves the construction quality of the anchor rod.
