Description
Technical field
The present invention relates to mine working, traffic tunnel, the supporting of water conservancy culvert, foundation supporting anchor rod system, tool
Body is related to a kind of enhanced bearing plate and anchor pole for tension and compression composite anchor-rod.
Background technique
The bearing capacity of tension and compression composite anchor-rod (such as patent No.: ZL201420450678.5 is disclosed) significantly improves, and engineering is made
Valence is greatly reduced, and is applied in Practical Project successively.Tension and compression composite anchor-rod technology side slope, foundation pit, water conservancy, dykes and dams,
In the anchoring engineerings such as mine and underground engineering, have broad application prospects.
Anchor head is exactly transferred to the big concentration of bearing plate by one of the mechanism that tension and compression composite anchor-rod bearing capacity significantly improves
Load resolves into two small concentrated forces by the effect of bearing plate, is shared jointly by pressure-bearing anchoring section and tension anchoring respectively.
After bearing plate squeezes grouting body, and then passed by the load that the cohesive force of grouting body and ground body interface shares pressure-bearing anchoring section
It is delivered in Rock And Soil.Therefore, when grouting body is squeezed by bearing plate, if the Compressive Bearing Capacity of grouting body is not able to satisfy design and wants
It asks, then pressure-bearing anchoring section grouting body strength failure can occur before grouting body is pulled out, it is low to directly result in anchor pole anti-pulling capacity
In design value, and then jeopardize the safety of anchoring engineering.In addition, may have folder soil or folder mud phenomenon when construction, before bearing plate,
Weaken the Compressive Bearing Capacity of pressure-bearing anchoring section grouting body.Therefore, there is an urgent need to take the relevant technologies to guarantee that tension and compression Composite Bolt is held
The Compressive Bearing Capacity of grouting body before pressing plate, and then guarantee the safety of tension and compression composite anchor-rod.
In consideration of it, the present inventor carries out in-depth study to the above problem, there is this case generation then.
Summary of the invention
The present invention uses common bearing plate for tension and compression composite anchor-rod in Practical Project, fills before may result in bearing plate
Slurry resistance to compression carries insufficient engineering problem, provides a kind of enhanced bearing plate, can significantly improve the Compressive Bearing Capacity of grouting body,
And convenient and quick construction, securely and reliably.
In order to achieve the above object, the present invention uses such technical solution:
A kind of enhanced bearing plate for tension and compression composite anchor-rod, including bearing plate, bearing plate are worn equipped with Grouting Pipe
Hole connects muscle slot equipped with multiple along axial one end, connects and be equipped with internal screw thread in muscle slot, further include more with muscle hole, the bearing plate is worn
A enhancing muscle, corresponding be threaded in of multiple enhancing muscle connect in muscle slot.
As a kind of preferred embodiment of the invention, multiple enhancing muscle parallel rings are located on the bearing plate.
As a kind of preferred embodiment of the invention, in 20-40mm, the depth of the thread groove exists the thickness of the bearing plate
5-20mm。
As a kind of preferred embodiment of the invention, the diameter of the enhancing muscle is 8-20mm, and the length of the enhancing muscle is
2-5 times of armature boring diameter.
The present invention relates to a kind of anchor poles, and including anchor rod body and the bearing plate for being set in anchor rod body, anchor rod body is in holding
One end of pressing plate axial direction is arranged with casing, and anchor rod body is equipped with limiting card in the other end of bearing plate axial direction, and bearing plate includes holding
Pressing plate, bearing plate are equipped with Grouting Pipe and perforate and wear muscle hole, and the anchor rod body is threaded through in muscle hole, and the bearing plate is along axis
To one end be equipped with it is multiple connect muscle slot, further include multiple enhancing muscle, multiple enhancing muscle correspondences, which are threaded in, to be connect in muscle slot.
Using technical solution of the present invention, certain hoop constraint can be formed to the body that is in the milk at bearing plate by enhancing muscle, thus
Improve the Compressive Bearing Capacity of pressure-bearing anchoring section grouting body;When bearing plate squeezes pressure-bearing anchoring section grouting body, due to setting for enhancing muscle
It sets, bearing plate base pressure can cohere work by enhancing muscle and the body that is in the milk by enhancing muscle and grouting body shared, enhancing muscle
It is shared grouting body with that on grouting body a certain range of before fractional load split-up to bearing plate, will reach and is undertaken the effect of load
Fruit greatly reduces the load that bearing plate bottom grouting body is subject to, improves grouting body resistance to compression bearing safety coefficient;It is deposited before bearing plate
In folder soil to a certain degree, since enhancing muscle and bearing plate are rigidly connected, load can pass through bearing plate-enhancing muscle-grouting body three
Interaction between person is finally transmitted in grouting body, effectively avoids bottom grouting body due to pressing from both sides soil caused by intensity wretched insufficiency
Bearing failure, and then anchor pole bearing capacity is avoided to fail.Enhance muscle by the way of being threadedly coupled, has the advantages that easy for construction.
