The utility model discloses by the drum by the pressure equipment put, the metal body of rod, metal tray and nut constitute, the drum by the end of pressure equipment set in the stock, including metal casing, high strong spring, spring plate and limiting plate, metal casing overlap on the metal body of rod, comprises and two parts spiro union upper and lower two parts, the metal body of rod drives the limiting plate and moves when receiving the die pull, forces high strong spring take place to deform and reach the effect of pressure of letting, the metal body of rod can effectively transmit metal tray with anchor power, metal tray lie in the tip of stock, can form effective resistance with the soil body, the nut be located anchor rod hole's outside, metal tray's upside. The utility model discloses simple structure, the construction of being convenient for, yielding property can just can effectively improve the anchor of stock and do all can by force.
Description
Technical field
This utility model belongs to underground engineering support technical field, is specifically related to a kind of underground engineering support pressure-relieving achor bar, particularly relates to a kind of cylinder pressure-relieving achor bar.
Background technology
Bolt anchorage technology is a kind of flexible reinforcement technique, it can make full use of the bearing capacity of Rock And Soil self and keep stablizing of rock mass, reinforcing body is made not to be destroyed. anchor pole strengthens the globality of Rock And Soil by anchoring, control the deformation of Rock And Soil after excavating, avoid the unexpected release of stress, thus ensureing that engineering is smooth, carry out safely. wherein pressure-relieving achor bar is owing to adopting the unexpected release allowing pressure device can effectively avoid stress, but the simple structure due to anchor pole, can anchorage part limited, especially conventional pressure-relieving achor bar only has the body of rod itself to provide anchor force, a lot of engineerings face the problem that anchor force is inadequate.
But without can reach allow pressure and increase measure and the method for anchor force simultaneously in current known pressure-relieving achor bar, in Bracing Process, hypodynamic phenomenon can be anchored owing to conventional pressure-relieving achor bar condenses relief at Anchor Agent, underground engineering support is created very big harmful effect.
Accordingly, it would be desirable to utility model one cylinder pressure-relieving achor bar, effectively to control stablizing of underground engineering.
Summary of the invention
The purpose of this utility model is to provide a kind of cylinder pressure-relieving achor bar, and this anchor pole can effectively solve the technical barrier that conventional pressure-relieving achor bar anchor force is low, and simple in construction, easy construction, Technological Economy are feasible.
Technical solution adopted in the utility model is: a kind of cylinder pressure-relieving achor bar, it is made up of by pressure device, metallic rod body, metal tray and nut cylinder；Described cylinder is positioned at the end of anchor pole by pressure device, including metal shell, high strong spring, spring backing plate and limiting plate, metal shell is made up of upper and lower two parts and two parts are spirally connected, when by pulling capacity, height strong spring can deform upon and reach to allow the effect of pressure, and cylinder increases anchoring area by pressure device and reaches to increase the effect of anchor force simultaneously；Anchor force can be effectively passed to metal tray by described metallic rod body；Described metal tray is positioned at the end of anchor pole, it is possible to form effective resistance with the soil body；Described nut is positioned at the outside of bolthole, the upside of metal tray.This utility model simple in construction, be easy to construction, yielding property can be strong, and can be effectively improved the anchor force of anchor pole.
Construction usage method of the present utility model is: a kind of cylinder pressure-relieving achor bar, during use, bolthole is accomplished fluently in assigned position, tunnel according to specification according to engineering specific requirement, wherein bolthole diameter should be greater than metal shell width, the bolthole degree of depth strictly observes designing requirement, then bolthole is cleared up again, ensure that bolthole hole wall must not have heavy quarrel and water body viscous, after having cleared up bolthole, cylinder is arranged on by pressure device combination the end of metallic rod body, then anchor pole is put into bolthole, again Anchor Agent is injected bolthole, cylinder is anchored by pressure device, finally after the setting time of regulation, with tensioning equipment, anchor pole is carried out stretch-draw, metal tray and nut are installed.
Operation principle of the present utility model is: a kind of cylinder pressure-relieving achor bar, and first this cylinder is positioned at the bottom of bolthole by pressure device, owing to adopting cylinder by pressure device, increases the lifting surface area of anchored end, increases anchor force；Wherein high strong spring can produce deformation when being subject to the pulling force of anchor pole exposed junction, reaches to allow the purpose of pressure.
The beneficial effects of the utility model are: a kind of cylinder pressure-relieving achor bar simple in construction, lightweight and in use construction is convenient rapidly, have reached to allow the effect of pressure, increase anchor force, have good economic benefits.
