Abstract
The invention discloses a recyclable anchor rod system for reinforcing joint surfaces of rocky slopes and a mounting method of the recyclable anchor rod system. The recyclable anchor rod system comprises a fixed anchor rod, a concrete precast element, a polyvinyl chloride (PVC) casing, a concrete fixed block and a recyclable anchor rod, wherein a threaded hole is opened in the concrete precast element, the tail end of the fixed anchor rod and the front end of the recyclable anchor rod are arranged in the concrete threaded hole oppositely, the PVC casing is sleeved on the recyclable anchor rod, one end of the PVC is embedded into the concrete precast element, and the other end of the PVC is embedded into the concrete fixed block. The system is simple in structure, convenient to operate, economical, practical and capable of anchoring rocky slopes with joints to improve the stress intensity of the anchor rod at joints; and the anchor rod can be recycled simultaneously.
Description
Technical field
The present invention relates to a kind of recoverable anchor rod system and mounting method thereof of reinforcing the rock side slope joint plane, specifically relate to a kind of by strengthen the also recuperable novel anchor rod of support action system at rock side slope joint plane position.
Background technology
At present, the total length anchor pole is of long duration in the reinforcing rock slope application in engineering, many scholars from theory and field trial to total length bolt support analyze the research of its power and the stressed distribution form of shear stress, the result shows that axle power and shear stress that anchor pole is subjected at the joint plane position are maximum, therefore must take the local stiffening measure to anchor pole, otherwise owing to can causing anchor pole, stressed inhomogeneities occurs destroying early than intended performance, reduce the stability of side slope, people's safety and national interests are caused potential harm.On the other hand, the disposable use of anchor pole also is very uneconomic to the waste of material, therefore is necessary anchor pole is recycled.
Summary of the invention
The objective of the invention is to have overcome deficiency of the prior art, a kind of novel anchor rod recoverable anchor rod system and mounting method thereof by strengthening support action and can recycle at rock side slope joint plane position is provided.
In order to solve the problems of the technologies described above, the present invention is achieved through the following technical solutions:
A kind of recoverable anchor rod system that reinforces the rock side slope joint plane, comprise fixing anchor bar, concrete precast element, PVC sleeve pipe, concrete fixed block, recoverable anchor rod, offer screwed hole in the middle of the concrete precast element, the tail end of fixing anchor bar and the front end of recoverable anchor rod are relatively arranged in the concrete screwed hole, sheathed PVC sleeve pipe on the recoverable anchor rod, the tail end of recoverable anchor rod arranges the concrete fixed block, one end of PVC sleeve pipe embeds in the concrete precast element, and the other end of PVC sleeve pipe embeds the concrete fixed block.
Described concrete precast element outer shape is quincunx or X, Y type.
A kind of mounting method of reinforcing the recoverable anchor rod system of rock side slope joint plane may further comprise the steps:
The first step, borehole is made anchor, and fixing anchor bar is squeezed into rock side slope;
In second step, the preparation concrete precast element is also offered screwed hole, fixing anchor bar tail end and recoverable anchor rod is screwed by screw thread enter anchor hole and contact with recoverable anchor rod until fixing anchor bar;
In the 3rd step, sheathed PVC sleeve pipe on the recoverable anchor rod is in the fixedly embedded concrete precast element of one end of PVC sleeve pipe;
The 4th step, preparation concrete fixed block, the concrete fixed block is arranged at the tail end of recoverable anchor rod, in the fixedly embedded concrete fixed block of the other end of PVC sleeve pipe;
In the 5th step, the anchoring of being in the milk is in the milk to concrete fixed block below.
Described concrete precast element is positioned at joint plane.
Concrete fixed block and recoverable anchor rod are fixed by lock nut.
Compared with prior art, the invention has the beneficial effects as follows: this apparatus structure is simple, and is easy to operate, economical and practical, carry out anchoring for the rock side slope that has the joint and can strengthen anchor pole in the force intensity that is subjected at joint place, and anchor pole can recycle, kill two birds with one stone.
Description of drawings
Fig. 1 is the layout plan that the present invention reinforces the recoverable anchor rod system of rock side slope joint plane;
Fig. 2 is the structural representation that the present invention reinforces the recoverable anchor rod system of rock side slope joint plane;
Wherein: 1 is rock side slope, and 2 is joint plane, and 3 is anchor pole; 4 is fixing anchor bar, and 5 is concrete precast element, and 6 is the PVC sleeve pipe, and 7 is the concrete fixed block, and 8 is recoverable anchor rod, and 9 is lock nut.
The specific embodiment
2 further specify embodiments of the present invention by reference to the accompanying drawings.
As shown in Figure 2, the present invention includes fixing anchor bar 4, concrete precast element 5, PVC sleeve pipe 6, concrete fixed block 7, recoverable anchor rod 8, lock nut more than 9 parts.Fixing anchor bar 4 heads are taper, and afterbody is shape of threads; Be screwed round steel pipe in the middle of the concrete precast element 5, fixing anchor bar 4 afterbodys and concrete precast element 5 screw by screw thread, and recoverable anchor rod 8 heads also screw also by screw thread with concrete precast element 5 and contact with fixing anchor bar 4.Concrete fixed block 7 is at recoverable anchor rod 8 afterbody fixing anchor bars, and in concrete fixed block 7 arranged outside lock nut 9, PVC sleeve pipe 6 gos deep into concrete precast element 5 and concrete fixed block 7 certain distances, and recoverable anchor rod 8 is sealed in the PVC sleeve pipe 6, realizes harmless the recovery.Position according to the determining positions concrete precast element 5 at joint, because concrete precast element 5 appearances are quincunx or X, Y shape, increased the contact area with the soil body greatly, also increased shear resistance, anti-pressure ability has avoided anchor pole to destroy owing to local pressure is inhomogeneous at the place, joint.
Key technology is to control the concrete precast element position at the joint plane position, so just can play the effect of strengthening curing.After finishing, to the anchor pole anchoring of being in the milk, lock at recoverable anchor rod afterbody concreting fixed block and with lock nut at last.For the recovery of anchor pole, as long as unload lock nut, the regular hexagon nut of counter-rotating recoverable anchor rod afterbody just can take out recoverable anchor rod in concrete precast element, simple to operate, time saving and energy saving.
