Abstract
The utility model provides a disjunctor formula lets in grades presses supporting device, includes the stock body of rod, the nut, and the damping gasket, the layer board, the one -level lets the pressure equipment put, prestressing force detection device, the second grade is put by the pressure equipment. The nut has the internal thread that matches with the stock body of rod, passes through threaded connection between the nut and the stock body of rod. Prestressing force detection device is the round territory steel sheet net of W type, can process according to the needs of on -the -spot prestressing force, and when reaching desired prestressing force value in the installation, prestressing force detection device will the yield deformation, is finally pressed into flatly. When because overlying strata strenuous exercise and when causing the stock to have great deformations, the one -level lets the pressure equipment put at first yield failure and realizes letting pressures, and when the stock receives bigger pressure, the second grade is put through the deformation realization by the pressure equipment and is let the pressure, greatly reduced the possibility broken too early of stock quilt to can maintain soft rock roadway under high stress's stability better.
Description
Technical field
The utility model is related to weak-soft rock entry under high stress supporting field, and in particular to a kind of Contiuum type classification allows pressure to prop up
Protection unit.
Background technology
Soft-rock slope control in Deep Roadway is always the difficult problem in process of coal mining, because deep rock mass is in multiple
Miscellaneous, heavily stressed Geological Environment Engineering, make mechanical characteristic that deep rock mass shows with often have during shallow mining it is very big
The strain softening of difference, especially high stressed soft rock and rheological behavior etc., not only deflection is big for country rock, and the continuous deformation time
It is long.As the most of collieries of China subsequently enter deep mining state, roadway support is difficult, and often duplicates and overhaul phenomenon,
Maintenance cost is high, and Deep Soft Rock Tunnel control becomes one of these enterprises crucial problem urgently to be resolved hurrily.
The content of the invention
To overcome existing technical problem, the utility model provides a kind of Contiuum type and is classified yield supporting device, adopt with
" high-strength high pre-stress ribbing anchor pole " has higher supporting intensity for the suspension device of core, for deep high stressed soft rock lane
Road, using the support system, can guarantee that country rock is slowly allowed pressure on the premise of certain supporting intensity, and a release part can not
The surrouding rock deformation of control, alleviates the pressure from surrounding rock that support system bears, and then reasonably using roadway surrounding rock from load, has
The control roadway surrounding rock large deformation of effect ground, safeguards stablizing for soft-rock tunnel.
The utility model is achieved through the following technical solutions：A kind of Contiuum type is classified yield supporting device, including anchor
Club shaft, nut, damping gasket, supporting plate, one-level allows pressure device, prestress detection device, and two grades allow pressure device, it is characterized in that：
The described two grades positions for allowing pressure device to be positioned close to roadway surrounding rock, its intensity allows the intensity of pressure device more than one-level；It is described pre-
Stress detection device is arranged on two grades and allows between pressure device and supporting plate, and prestressing force during suspension device is installed for detection；It is described
One-level allows pressure device to be arranged between two supporting plates, the yield failure first when country rock is to press；The nut has and anchor rod body
The internal thread for matching, is threaded connection between nut and anchor rod body.
Preferably, the anchor rod body be high-strength high pre-stress anchor rod body, if on anchor rod body as needed added with
A dry spherical rib block, rib block is twisted together with anchor rod body, and for slow down suspension device pressure speed is allowed.
Preferably, described two grades allow pressure device, and it is in the middle of hollow semi-cylindrical by the rammed two of hot-rolled steel to be one
For the combined shell of hollow cuboid, after one-level allows pressure device destruction, anchor is produced due to the strenuous exercise of overlying rock
When bar continues moderate finite deformation, two grades pressure device yield deformation can be occurred plays to continue to allow pressure to act on, so as to prevent anchor pole too early
Be pulled off, efficiently control roadway surrounding rock large deformation, safeguard stablizing for soft-rock tunnel.
Preferably, the prestress detection device is the expanded metal lath of W types, can carry out adding according to the prestressed needs in scene
Work, when required prestress value is reached in installation process, prestress detection device will yield deformation, be finally pressed into flat
's.
Preferably, the nut has the internal thread matched with anchor rod body, and screw thread is passed through between nut and anchor rod body
Connection.

It is characterized in that：The described two grades positions for allowing pressure device 4 to be positioned close to roadway surrounding rock, its intensity allows the strong of pressure device more than one-level
Degree；The prestress detection device 6 is arranged on two grades and allows between pressure device and supporting plate, for pre- during detection installation suspension device
Stress；The one-level allows pressure device 3 to be arranged between two supporting plates, the yield failure first when country rock is to press；The nut 1 has
The internal thread matched with anchor rod body, is threaded connection between nut and anchor rod body.
Described two grades the width of pressure device 4 and the quantity of anchor hole can be processed according to the needs at scene, this practicality
It is new only to be illustrated with the Contiuum type classification yield supporting device for being provided with three anchor holes.
A kind of Contiuum type is classified the specific embodiment of yield supporting device：First anchor rod body 6 is inserted into into country rock
In anchor hole, by its front end by Anchor Agent together with rock anchorage；Then expose on a section of country rock successively in anchor rod body
Load onto two grades and allow pressure device 4, prestress detection device 6, supporting plate 7, one-level allows pressure device 3, damping gasket 2, nut 1；Finally revolve
Tight nut, when the prestressing force required for reaching support system, prestress detection device 6 will yield deformation, when prestressing force will
The nut 1 that stops the rotation when device 6 is driven plain is surveyed, so as to form complete support system.
