Description
Technical field
The utility model is related to a kind of multistage allows pressure to warn anchor pole, belongs to branch anchoring engineering field.
Background technology
Increasingly increase with the intensity and difficulty of Development of Underground Engineering, soft-rock tunnel, tunnel support, which turn into, restricts safety, height
Imitate a problem of construction.As underground engineering depth constantly increases, great burying, the geological conditions of high-ground stress show crustal stress
Increase is write, surrouding rock stress poised state is destroyed, and country rock produces large deformation to discharge strain energy initial stage, and deep tunnel is shown
The characteristics of new, such as roadway deformation speed is fast, deflection is larger, pucking is serious.Common bolt reaches in surrouding rock deformation displacement
Or more than anchor pole maximum deformation quantity when, it may occur that anchor pole tensile failure model phenomenon, in order to more effectively play the reinforcing of anchor pole and
Acted on of both release, it is carried jointly with roadway surrounding rock and the removable part component of stress, it is desirable to which anchor pole has certain pressure that allows
Ability and enough strength and stiffness.In addition, staff can not accurately understand anchor force and reaction when carrying out anchoring work
The situation of power, anchor force deficiency can cause to produce harmful effect to underground support engineering, once country rock is to caused by suspension roof support
When reaction force and the anchor force applied are increased to beyond the power that anchor pole can bear, suspension roof support is just destroyed, it is possible to
Serious cave in accident occurs.How to increase pressure-relieving achor bar allows pressure energy power to understand anchor force and the feelings of reaction force with accurate
Condition, farthest plays the effect of pressure-relieving achor bar, and this technical barrier is badly in need of solving.
China State Intellectual Property Office discloses one entitled " a kind of cylinder pressure-relieving achor bar ", Shen on July 27th, 2016
Please number utility application for being 201620180357.7.The patent provides a kind of cylinder pressure-relieving achor bar, conventional to solve
The problem of pressure-relieving achor bar installation is complicated, and anchor force is low, the utility model is additionally arranged cylinder by pressure device, and described cylinder allows press fitting
Metallic rod body is enclosed on setting in the end of anchor pole, including metal shell, high strong spring, spring backing plate and limiting plate, metal shell
On, it is made up of upper and lower two parts and two parts is spirally connected, metallic rod body drives limiting plate motion when by pulling capacity, forces high-strength
Spring, which deforms upon, has the function that to allow pressure；Anchor force can be effectively passed to metal tray by described metallic rod body；It is described
Metal tray be located at the end of anchor pole, effective resistance can be formed with the soil body, the patent efficiently solve increase pressure-relieving achor bar
Allow pressure energy power, and the anchor force of anchor pole can be effectively improved.But the contraction of pressing spring is allowed to grow when the displacement of country rock exceedes
Degree, makes pressure device just ineffective, if country rock continues to be deformed, this single-stage pressure-relieving achor bar be able to may not reach
Preferable supporting effect, and and unresolved the problem of how accurately understanding anchor force and reaction force.
The content of the invention
In order to overcome current existing pressure-relieving achor bar to make pressure scarce capacity and understanding anchor force and the situation of reaction force too late
When the problem of, the utility model provide a kind of multistage allows pressure warning anchor pole.
To solve the above problems, the utility model adopts the following technical scheme that：
（1）Multistage allows pressure warning anchor pole to allow pressure device, friction pad by anchor rod body, pallet top plate, tray substrate, multistage
Plate, clamp nut and warning mark composition.
（2）The pallet top plate is fixedly installed on anchor rod body, and tray substrate is provided with below pallet top plate with enclosing
Rock is contacted, and the clamp nut is connected by the backing plate that rubs with pallet top plate, is set between pallet top plate and tray substrate multistage
Allow pressure device.
（3）The multistage allow pressure device mainly include it is high-strength allow pressing spring, allow outside gland cylinder, interior allow gland cylinder and allowing to overwhelm
Nematophore.It is outer allow gland cylinder and it is interior allow gland cylinder fixed welding tray substrate and pallet top plate respectively, it is high-strength to allow pressing spring to be arranged at
Inside allow pressure sleeve inner, be fixedly connected with pallet top plate and tray substrate, allow overwhelm nematophore be respectively welded in it is external allow gland cylinder and
The inscribed inside for allowing gland cylinder, in the opposite direction, quantity is 16.
（4）The warning mark allows the outside of gland cylinder in being arranged at, and the composition of warning mark is luminous paint.
The beneficial effects of the utility model are：A kind of multistage provided by the utility model allows pressure to warn anchor pole, can be to supporting
Engineering plays good effect.It is high-strength to allow pressing spring compressive deformation first and then realization when moderate finite deformation occurs for roadway surrounding rock
One-level allows pressure, because interior allow and allows allowing in gland cylinder to overwhelm nematophore intensity to be more than the high-strength intensity for allowing pressing spring gland cylinder outside,
When deformation of the surrounding rock in tunnel further increases, and it is high-strength allow pressing spring can not continue deformation allow pressure when, inside allow gland cylinder and the outer pressure that allows
Allowing in sleeve overwhelms nematophore stress deformation, and then realizes and allow pressure again, therefore realizes that multistage allows pressure and protects anchor pole from drawing
It is disconnected.Security staff and user of service is caused to understand the situation of fastening force and reaction force in time additionally by setting warning mark,
After finding that reaction force exceedes setting, measure can be used immediately, prevents accident.
