Abstract
The invention relates to a novel high-strength and high-deformation piston type inverted arch. The novel high-strength and high-deformation piston type inverted arch is characterized by comprising an arc-shaped metal box component (1), an arc-shaped metal steel plate (2), slots (6), anchor rod holes (3) and filling materials (4). A tunnel floor is supported by the novel high-strength and high-deformation piston type inverted arch; the novel high-strength and high-deformation piston type inverted arch follows a principle of combination of softness and hardness; and yielding is realized, the floor can deform properly, part of pressure is released, a supporting effect is strengthened, further deformation of the tunnel floor is limited, and overall stability of a tunnel supporting structure is guaranteed.
Description
Technical field
Patent of the present invention relates to arch of the anti-end of a kind of novel high-strength large deformation piston type.
Background technology
In Deep Mine recovery process, complex geologic conditions is changeable, add the impact of high-ground stress and mine motive force disaster, cause roadway deformation seriously, even scrap that (pucking is serious, two help wall caving and roof caving), a lot of tunnels need repeatedly be keeped in repair, and can not ensure mine normal production, and this class tunnel improvement must be adhered to controlling side and first control end principle.Serious for Floor Heave in Roadway, mainly adopt at present following means: the multiple supporting means such as destressing method, arch of the anti-end of concrete, jacking of floor method, but DeGrain.The anti-end of concrete arch has enough large compressive strength, but is out of shape limitedly, cannot adapt to base plate large deformation, and Bottom Pressure causes more greatly supporting and protection structure inefficacy, breaks.Administer pucking and need follow " allow pressures ", " resistance to compression " feature, both allowed base plate suitably be out of shape, supporting intensity is greatly provided enough again.Therefore need that design is a kind of not only " to have been allowed " but also the combined supporting structure of " resist " badly, control roadway deformation under Deep Mine soft-rock tunnel and dynamic disaster, so propose the anti-end of high strength large deformation piston type, encircle, solve the serious difficult problem of this type of Floor Heave in Roadway.
Existing technical scheme: the supportings such as base plate release, jacking of floor, grouted anchor bar, arch of the anti-end of concrete, these supportings can not embody " just " " soft " combination, cannot fundamentally solve base plate large deformation, just delay base plate and overhaul time and number of times.
Shortcoming is: existing support technology is mainly to strengthen base plate supporting and pressure relief vent (groove), allows roadway's sides pressure shift to base plate deep, alleviates base plate supporting pressure.When roof weighting, base plate supporting and protection structure first lost efficacy, destroyed often, caused whole roadway support structural instability, and roadway deformation is serious, need again overhaul.
Patent object of the present invention: this supporting and protection structure considers pressure, the resistance to compression feature of allowing, had both allowed base plate have to a certain degree distortion, and release portion pressure from surrounding rock can provide again enough large supporting intensities, and restriction base plate is further out of shape.This supporting and protection structure good stability, the degree of reliability are high, consuming time short, and it and top, tunnel, portion of side Yieldable steel support or anchor pole (rope) supporting association are used, can effectively control Floor Heave in Roadway, guarantee tunnel resistance to overturning, avoid tunnel to lose efficacy because coal seam floor failure causes integer support.
Summary of the invention
The invention provides arch of the anti-end of a kind of novel high-strength large deformation piston type, it is characterized in that comprising circular arc-shaped metal box member (1), circular arc-shaped metal steel plate (2), draw-in groove (6), bolthole (3) and packing material (4),
Described circular arc-shaped metal box member (1) is hollow structure, inner side surrounding has draw-in groove (6), the inner circular arc-shaped metal steel plate (2) of placing of this draw-in groove (6), this circular arc-shaped metal steel plate (2) can be in draw-in groove (6) reciprocates inside, the hollow bulb of described circular arc-shaped metal box member (1) has packing material (4), has a plurality of boltholes (3) on described packing material (4).
Four jiaos of described circular arc-shaped metal box member (1) have hinged (5).
Described bolthole (3) is positioned at the middle part of the hollow bulb of circular arc-shaped metal box member (1).
Arch of the anti-end of a kind of novel high-strength large deformation piston type as claimed in claim 1, is characterized in that described packing material (4) is foamed plastics.
Described bolthole (3) inside has the metal sleeve that restriction anchor pole moves.High strength large deformation anchor rod diameter is consistent with metal sleeve internal diameter, and sleeve pipe effect is O-ring curved metal box inner foam plastics on the one hand, and enough large frictional force is provided on the other hand, stops metal sheet 2 to move up, and deformation space is provided.Roadway floor extrusion metal box distortion and circular arc-shaped metal box itself provide certain deformation space as Supporting Structure deformation for Floor Heave in Roadway, release portion pressure from surrounding rock, then pass through high strength large deformation anchor rod, further limit surrouding rock deformation.
Beneficial effect:
The arch of the anti-end of high strength large deformation piston type of this patent design is realized bilayer and is allowed pressures, the supporting of reinforcement base plate, and supporting and protection structure is recyclable.This patent supported laneway base plate, follows the principle of coupling hardness with softness, and has both embodied to allow pressure, allows base plate suitably be out of shape, and release portion pressure, adds strong supporting again, and restriction roadway floor is further out of shape, and ensures that roadway support structural entity is stable.
