Abstract
In order to overcome support anchor rod producing the problem of slipping in overcoming the geological conditions such as fragmented rock body or soft soil layer, the utility model provides a kind of resistance to plucking expansion anchor rod, including drill bit, expand hangnail, sleeve, Grouting Pipe, deformed bar, grout outlet, stop grouting plug and anchorage, the expansion hangnail is made of strip steel plate, by being bolted on sleeve, this is connected as being flexibly connected, easy to sleeve movement, the stretching of hangnail.The expansion anchor rod, by tensioning slip casting steel pipe, can drive expansion hangnail outwards to expand after rock mass or the soil body is pierced, and the embedded soil body or fragmented rock body, expand anti-skidding hangnail and firmly catch rock mass or the soil body, substantially increase its breakout capacity.
Description
Technical field
Anchor in Geotechnical Engineering supporting field is the utility model is related to, more particularly to a kind of resistance to plucking expansion anchor rod.
Background technology
Suspension roof support is a kind of main support pattern among the underground engineering such as tunnel, foundation pit, has that support cost is low, branch
Protect positive effect, the advantage such as speed of application is fast, labor intensity is low.And traditional anchor pole is usually small with the contact area of country rock, resist
Pull out force is small, when carrying out anchor cable locking, easily causes anchor cable to produce slippage, triggers supporting accident；The bar resistance to plucking of traditional anchor is advocated
If determined by soil layer frictional resistance, anchoring section diameter, anchorage length etc..In weak soil, ground anchor resistance is relatively low, and rock-bolt length
In the case of being restricted, its anchor pole plays the role of just greatly reducing to be solved anchor cable to exist therefore, it is necessary to a kind of new device
The problem of slippage is produced in the geological conditions such as fragmented rock body or soft soil layer.
Utility model content
In order to overcome support anchor rod producing the problem of slipping in overcoming the geological conditions such as fragmented rock body or soft soil layer, this
Utility model provides a kind of resistance to plucking expansion anchor rod, which can pass through tensioning slip casting after rock mass or the soil body is pierced
Steel pipe, drives expansion hangnail outwards to expand, and the embedded soil body or fragmented rock body, expand anti-skidding hangnail firmly catch rock mass or
The soil body, substantially increases its breakout capacity.
The utility model uses following technical solution：
A kind of resistance to plucking expansion anchor rod includes drill bit, expands hangnail, sleeve, Grouting Pipe, deformed bar, grout outlet, is only starched
Plug and anchorage, the expansion hangnail are made of strip steel plate, and by being bolted on sleeve, this is connected as being flexibly connected, and is easy to
Sleeve is mobile, the stretching of hangnail.
The expansion hangnail, its outer end are barb-like groove, prevent hangnail from coming off, its inner end is projecting slot, is prevented
Expansion hangnail is expanded to be caused to fail more.
Preferably, the Grouting Pipe is round steel pipe, its bottom is fixed for high strong spring, and end is cylinder spiral shell thereon
Line.
Preferably, its size of the grout outlet is matched with expansion hangnail, and bigger 2mm to 3mm than expansion hangnail.
Preferably, the sleeve is fixed in Grouting Pipe, and 8 expansion hangnails are equipped with above a sleeve, are divided into upper and lower two
Row, often arranges each four.
The deformed bar, its lower end are embedded in outer casing bottom, and the other end carries out prestress anchoraging with anchoring instrument.Make
Resistance to plucking expansion anchor rod plays effect.
The beneficial effects of the utility model are：（1）What the interior setting expansion hangnail of resistance to plucking expansion anchor rod can fasten is embedded in
Fragmented rock body or among carrying, increases its breakout capacity.（2）The Grouting Pipe can control the degrees of expansion of expansion hangnail, energy
Enough adapt to various complex geological conditions.
