Description
Technical field
The present invention relates to mine timbering field, more particularly to a kind of lane for being used to have bump, deep-well, big cross section
Press alley hydraulic support structure road protecting against shock.
Background technology
As China's economic is skyrocketed through for a long time, be imbedded in the coal of stratum superficial part and various minings obtain it is closely withered
Exhaust, thus pit mining depth has broken through 1000m, the accumulation and release that ground pressure is big, pressure change is complicated, performance is hit by a bullet in rock stratum are all
It has been normality, there have been deep-well, big cross section, has there is the roadway support problem of bump.
At present, using U-shaped steel as excavation support made of the section bar of representative, it can not meet deep-well, big cross section, there is punching
The roadway support requirement pressed with hitting.In order to make up this defect, a collection of new alley hydraulic support is developed in recent years, such as：
Press hydraulic support, lift capplce hydraulic support protecting against shock.Although this kind of stent compensate for U-shaped just for made of the section bar of representative
The defects of excavation support support force is insufficient.But due to the limitation of its structure, it is larger to take the space in tunnel, is not easy in tunnel
It is current, and it is unsatisfactory for the pressure support effect of tunnel side.

The 4th otic placode is equipped with the inside of blind end, the second openend of the outer barrel is slidably located on the outside of the first openend of inner cylinder, institute
State and be connected with the first hydraulic strut between the second otic placode and the 4th otic placode.
Coordinate inner cylinder and outer barrel to realize the supporting role of alley hydraulic support structure after the elongation of first hydraulic strut, work as tunnel
When ground pressure increase or burst bump cause tunnel reduced cross-sectional, the first hydraulic strut drainage retraction, and by increased
Pressure and burst bump are transferred on the country rock of stent support, so as to fulfill the branch protective function of excavation support.
Further, the cylinder arm of the inner cylinder and outer barrel is arc-shaped, and inner cylinder and outer barrel along arc axis slide relatively
It is dynamic.
Further, the 5th otic placode, the second blind end of the outer barrel are additionally provided with the outside of the first blind end of the inner cylinder
Outside is equipped with the 6th otic placode, and the second hydraulic strut is equipped between the 5th otic placode and the 6th otic placode.
Further, the cross section of the inner cylinder and outer barrel is rectangle.
The structure construction is simple, relative inexpensiveness, and supporting effect is good；It can arbitrarily set what is connected into by hydraulic support
The shape of annular；Possess than shaped steel such as：The intensity of the biggers such as U-shaped steel, I-steel；Employ the connection that contracts of suitable steel construction piece
Mode is connect, can actively allow pressure and energy-absorbing, press the destruction to tunnel with slowing down, can be in deep-well tunnel, large section roadway, pressure
Unstable tunnel, bump are inclined to larger tunnel and effectively substitute other support patterns；It is transversal to be adapted to various tunnels
Face, can adjust and bear pressure value and pressure direction, easy disassembly and recycling, reduce tunnel comprehensive support cost, can give equipment
Laying and pedestrian leave abundant space.
