Description
Technical field
The present invention relates to a kind of centering holders for tension and compression composite anchor-rod pressure-bearing anchoring section.
Background technology
Bolt support technology is widely used to building, water conservancy, mining industry, friendship as a kind of support technology efficiently, economic
In the engineering constructions such as logical, urban infrastructure and hazards control, and play extremely important effect.And anchor pole is as anchor
Gu a key components in engineering, the quality of construction quality will have a direct impact on the anchoring effect of anchor pole.It was constructing
Cheng Zhong, to ensure that anchor rod body is positioned over the middle of drilling, often holder makes the body of rod in welded reinforcement pair on the body of rod
Centering.The transfers that power can be effectively ensured in of the body of rod and keep injecting cement paste radial force uniform.But for soil property
Softer stratum, Steel bar rack are easy to be pressed into the soil body because the body of rod is conducted oneself with dignity, and cause the body of rod to deviate centre position, or even be affixed on brill
Hole wall.After bored grouting, can answer the body of rod deviate centre position and make the body of rod and injecting cement paste water ratio limit power substantially weaken, reduction
Anchor pole anti-pulling capacity, jeopardizes engineering safety.
Tension and compression composite anchor-rod has a pressure-bearing anchoring section and tension anchoring section simultaneously, under identical anchorage length, bearing capacity
2 times or more are improved than conventional anchor, there is wide future in engineering applications, such as application No. is in 201410391335.0
This kind of tension and compression composite anchor-rod is disclosed in state's patent application.The tension anchoring section body of rod and injecting cement paste of tension and compression composite anchor-rod are straight
Bonding is connect, and the pressure-bearing anchoring section body of rod is because will ensure the direct transmission of total load head, it is necessary to overall length uses PVC casings or other to arrange
It applies and is wrapped up, and be connected in the free section body of rod, the body of rod is made to be isolated with injecting cement paste.Under normal circumstances, tension anchor
Gu the section body of rod can guarantee that the body of rod is placed in the middle using traditional welding steel bracket, and the pressure-bearing anchoring section body of rod is made due to outer wrapping PVC casings
The installation for obtaining centering holder can have following two prominent questions：(1) because of the pressure-bearing anchoring section body of rod of tension and compression composite anchor-rod
Must use casing that it be made to be isolated with injecting cement paste, thus can not directly on casing holder in welded reinforcement pair；(2) opposite
In weak soil layer, traditional reinforcing bar centering holder because with hole wall contact area very little, be easy to conduct oneself with dignity because of the body of rod and sink to the soil body, lead
It causes the body of rod to deviate drilling centre position, to influence the uniformity of rockbolt stress transmission and grouting body stress, and then influences anchor pole
Bearing capacity.
Centering construction based on problem above to tension and compression composite anchor-rod pressure-bearing anchoring section brings great difficulty, in the past
Traditional reinforcement welding centering holder cannot achieve.The present inventor carries out in-depth study to the above problem, there is this case generation then.
In consideration of it, the present inventor carries out in-depth study to the above problem, there is this case generation then.
