Detailed description of the invention
Below in conjunction with accompanying drawing, technical scheme is clearly and completely described, it is clear that described enforcement
Example is a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, ordinary skill
The every other embodiment that personnel are obtained under not making creative work premise, broadly falls into the scope of protection of the invention.
In describing the invention, it should be noted that term " " center ", " on ", D score, "left", "right", " vertically ",
Orientation or the position relationship of the instruction such as " level ", " interior ", " outward " they are based on orientation shown in the drawings or position relationship, merely to
Be easy to describe the present invention and simplifying describe rather than instruction or the hint device of indication or element must have specific orientation,
With specific azimuth configuration and operation, therefore it is not considered as limiting the invention.Additionally, term " first ", " second ",
" the 3rd " is only used for describing purpose, and it is not intended that indicate or hint relative importance.
In describing the invention, it should be noted that unless otherwise clearly defined and limited, term " is installed ", " phase
Even ", " connection " should be interpreted broadly, for example, it may be fixing connection, it is also possible to be to removably connect, or be integrally connected；Can
To be mechanical connection, it is also possible to be electrical connection；Can be to be joined directly together, it is also possible to be indirectly connected to by intermediary, Ke Yishi
The connection of two element internals.For the ordinary skill in the art, can understand that above-mentioned term is at this with concrete condition
Concrete meaning in invention.
Bump, also known as rock burst, refers to roadway or work surface surrounding rock body, due to elastic deformation energy instantaneous relase and
Produce the dynamic phenomenon destroyed suddenly acutely, be often accompanied by coal and rock dish out, the phenomenon such as loud noise and blast；Owing to bump has
The biggest destructiveness, and its typically no macroscopic view omen before generation, but with suddenly, drastically, fierce form is by coal and rock
Dish out, thus be not only able to cause support to damage, side fall roof or tunnel blocking, and also result in workmen injured by a crashing object,
Traumatic injury or squeeze wound, even can make time serious workmen because tunnel blocking and death by suffocation, therefore, bump is at world wide
Interior coal mine is considered as one of the most serious natural disaster；At present, along with being continuously increased of China's coal-mine mining depth,
Rock blast hazard also presents increasingly severe trend, and this gives Safety of Coal Mine Production and the life security of vast Coal Mine Staff
Cause threat greatly.
Below by specific embodiment and combine accompanying drawing the present invention is described in further detail.
Mine stalk semicircular arch tunnel erosion control support, referring to the drawings 1 and 2, including wire netting 1, yieldable trapezoid support
2, crown 3 and base 4, uses hydraulic vertical prop 5 to be connected between described crown 3 and base 4；Described wire netting 1 is layed in wall
Surface；Described trapezoid support 2 is between described crown 3 and base 4.Described hydraulic vertical prop 5 ensure that crown 3 and base 4 it
Between bonding strength and certain deformation energy-absorbing function；Described wire netting 1 can strengthen the intensity on wall surface；Described trapezoidal
Support 2 has higher setting load, and supporting intensity is big；When shoulder bed effects pressure on erosion control support in the application reaches certain
During value, described trapezoid support 2 just producing surrender contracting dynamic, the dynamic result that contracts makes shoulder bed effects on erosion control support in the application
Pressure declines, thus the pressure avoiding country rock causes the destruction of support more than the bearing capacity of described erosion control support；For lane
The structural intergrity of road wall, without destroying, presses effect with improve the shock resistance of erosion control support, it is ensured that equipment and construction in tunnel
The safety of personnel.
Further, even application concrete layer 6 is in the surface of described wire netting 1；The thickness of described concrete layer 6 is
4cm～8cm.Effectively wire netting 1 is fixed on the wall of tunnel, strengthens wall surface impact strength.
Further, tunnel length direction use hydraulic telescopic arm 7 be connected between adjacent described base 4.Hydraulically extensible
Arm 7 enhances in the application telescopic shape change ability on erosion control stent length direction, ensure that the end when by bump effect
Connective stability between seat 4.
Further, described crown 3, base 4 are respectively equipped with flexible clamp piece 8 with the junction of described hydraulic vertical prop 5.At this
When in patent application, erosion control support is by bump effect, flexible clamp piece 8 is advantageously implemented the deformation of junction, it is achieved described
The contraction that erosion control support is overall.
Further, described trapezoid support 2 is U-shaped steel construction.
Further, the outer surface of described crown 3 and tunnel net section Corresponding matching；The inner surface of described crown 3 is ripple
Stricture of vagina face structure.When in the face of bump, corrugated surface structure can realize the local rapid desufflation of the application erosion control support, it is achieved encloses
Stepping down of rock, and then ensure that the energy-absorbing of stepping down that support is overall, it is ensured that the safety in tunnel.
Last it is noted that above example is only in order to illustrate technical scheme, it is not intended to limit；Although
With reference to previous embodiment, the present invention is described in detail, it will be understood by those within the art that: it still may be used
So that the technical scheme described in previous embodiment is modified, or the most some or all of technical characteristic is equal to
Replace；And these amendments or replacement, do not make the essence of appropriate technical solution depart from the model of embodiment of the present invention technical scheme
Enclose.
