Description
Technical field
This utility model relates to underground mining engineering, especially relates to a kind of soft-rock tunnel pucking preventing and treating device.
Background technology
Underground mining enters deep, and Floor Heave in Roadway is the most common.Clayey or mud stone base plate are soaked by the infiltration of water and expand, the most serious transport that have impact on tunnel and normal use, the normal safety in production of impact.Administering roadway floor protuberance and need bigger maintenance load, waste of manpower, material resources, maintenance cost is the highest.Preventing and treating for soft-rock tunnel heave can use bar to squeeze into oblique anchor pole at base angle, tunnel, has certain effect to preventing and controlling, but globality is poor, easily produces local harm.And at base plate, squeeze into vertical anchor pole or use campshed supporting, process during the then clear end in tunnel when base plate generation unstability and more bother.
Summary of the invention
The purpose of this utility model is to provide a kind of soft-rock tunnel pucking preventing and treating device, and this structure can undertake roadway's sides and loosen country rock and be delivered to the partial pressure of base plate, plays the effect of supporting base plate, thus prevents heave phenomenon from occurring.
The purpose of this utility model is achieved in that
A kind of soft-rock tunnel pucking preventing and treating device, feature is: include the steel truss girder being laid on the base plate in tunnel, it is provided with girder steel perforate at the junction point that latticed steel truss girder is crisscross, it is provided with the oblique drilling hole corresponding with the girder steel position of opening of steel truss girder both sides in the base plate both sides in tunnel, the vertical boring corresponding with the girder steel position of opening in the middle part of steel truss girder it is provided with in the middle part of the base plate in tunnel, the bottom of anchor rod body is inserted in oblique drilling hole and the vertical boring of base plate, top with externally threaded anchor rod body is upward through the girder steel perforate of steel truss girder, by disc and bolt, anchor rod body is fixed on the bottom of steel truss girder, it is filled with, in oblique drilling hole and vertical boring, the injecting cement paste wrapped by anchor rod body, steel truss girder is made to be fixed on the base plate in tunnel, concrete cover it is equipped with on steel truss girder.
It is provided with boring bottom at oblique drilling hole and the bottom of vertical boring, the bottom of anchor rod body.
Girder steel perforate equally arranges.
The degree of depth of oblique drilling hole and vertical boring is more than the relaxation zone thickness of roadway's sides.
Anchor rod body, steel truss girder, concrete cover are fixed together by this utility model, form an overall structure, assume responsibility for the pressure of roadway floor, serve the effect of supported laneway base plate, thus prevent the phenomenon of Floor Heave in Roadway from occurring.On the one hand concrete cover can prevent this structure from being damaged by the external world, is on the other hand easy to the walking of staff and the transport in tunnel.Steel truss girder can make of the steel of the type such as channel-section steel, steel plate.
Therefore, this utility model has and can undertake roadway's sides and loosen country rock and be delivered to the partial pressure of base plate, supporting base plate, prevent preferable, the safe and practical advantage of heave, easy construction, supporting effect.
