Abstract

The utility model relates to a slope reinforcement technical field, specific theory relates to a resistance to plucking ground slope reinforcement device shears, it includes its characterized in that steel strand wires, consolidates muscle, barb, consolidating one section in muscle and being cylindric, another section is coniformly, consolidates the cylindric section of muscle and goes up that fixed welding has a plurality of barb along its curved surface lateral wall on, consolidates muscle and barb and is the reinforcing bar material, steel strand wires one end and fixed linking to each other of the cylindric section one end of reinforcement muscle, the barb top is to the steel strand wires lopsidedness. The utility model has the advantages of shear behavior is good, and the resistance to plucking performance is good, the reinforcement of side slope when being applicable to highway, railway, foundation ditch, opencut construction operation.

Description

A kind of shearing resistance resistance to plucking geotechnical slope bracing means

[technical field]

This utility model relates to reinforcing side slope technique field, more particularly to a kind of shearing resistance resistance to plucking geotechnical slope bracing means.

[background technology]

The landslide of side slope, break away, the factor such as cave in is the major casualty sexual factor of slope failure, builds highway, railway, base the most at home In the engineering practices such as hole, opencut, a large amount of employing anchorage technologies reinforce geotechnical slope, and the anchor pole that anchorage technology is used is usually a linear type anchor Muscle, after reinforcing side slope, there is side slope discontinuity, the shortcoming of slope protection difference in it, particularly when reinforcing the geotechnical slope of air slaking, if anchor pole Anchorage depth not enough, the unstable failure phenomenon of anchor structure can easily occur, thus in engineering practice, often require that anchor pole has enough length And anchorage depth, this is unfavorable for the overall stress of anchoring-bolt system on the contrary, makes its shear behavior of anchor pole reinforced poor on the contrary, it is impossible to bear under Rock And Soil The sliding moment of flexure shearing force caused, thus easily cause anchor pole and be broken off destroying, thus carry out its poor effect reinforced of reinforcing side slope merely with anchor pole.

[utility model content]

The technical problems to be solved in the utility model is to provide a kind of shearing resistance resistance to plucking geotechnical slope bracing means, and it is good that it has shear behavior, resistance to plucking The advantage that performance is good, it is adaptable to the reinforcing of side slope when highway, railway, foundation ditch, opencut construction operation.

In order to achieve the above object, the technical scheme that this utility model provides is: a kind of shearing resistance resistance to plucking geotechnical slope bracing means, its feature exists Steel strand wires, rinforcement bar, agnail is included in it；Described rinforcement bar one section is cylindrical, and another section is coniform, bent along it on cylindric section of rinforcement bar It is fixedly welded with several agnails, rinforcement bar and agnail on the sidewall of face and is reinforcing bar material；Described steel strand wires one end is solid with cylindric section of one end of rinforcement bar Fixed connected；Described agnail top is to steel strand wires lopsidedness.

The beneficial effects of the utility model are: it is good that this utility model has shear behavior, the advantage that extraction-resistant behavior is good, it is adaptable to highway, railway, The reinforcing of side slope when foundation ditch, opencut construction operation.

[accompanying drawing explanation]

With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.

Fig. 1 is structural representation of the present utility model.

Fig. 2, Fig. 3 are view when this utility model uses.

Wherein, 1-steel strand wires, 2-rinforcement bar, 3-agnail, 4-locking member, 5-backing plate, 6-waist rail, 7-reinforce baffle plate, 8-concrete, 9- Reinforcing area.

[detailed description of the invention]

In example shown in the drawings, as it is shown in figure 1, a kind of shearing resistance resistance to plucking geotechnical slope bracing means, it is characterised in that it include steel strand wires, Rinforcement bar, agnail；Described rinforcement bar one section is cylindrical, and another section is coniform, fixing welding along its curved surface sidewall on cylindric section of rinforcement bar Several agnails, rinforcement bar and agnail is had to be reinforcing bar material；One end, cylindric with rinforcement bar section of described steel strand wires one end is fixedly linked；Described agnail Top is to steel strand wires lopsidedness.

This utility model is applicable to the reinforcing of side slope when highway, railway, foundation ditch, opencut construction operation, its construction step when reinforcing side slope Suddenly it is preferably as follows:

1. construction operation personnel survey place, determine the particular location of reinforcing area and ruggedized construction, determine the degree of depth and the aperture of boring, determine that steel twists Line, the size of rinforcement bar；2. holing, hole domatic vertical with reinforce, angle of inclination is less than 2 degree；3. by the cone of rinforcement bar At the bottom of Duan Yiduan putting hole, aperture after in concrete perfusion；4. irrigate complete after concrete setting, to hole outside steel strand wires carry out stretch-draw and fix, Being coated with one layer of securing plate on the most domatic, reinforce and add waist rail on baffle plate, backing plate is withstood on waist rail top, finally arranges locking member on steel strand wires and executes Prestressing, holds out against waist rail (see Fig. 2) by backing plate.

Owing on rinforcement bar, the concrete barb of perfusion can be lived by the agnail of welding so that after this utility model stretch-draw is fixing, its extraction-resistant behavior increases By force, the beneficially reinforcing of side slope, additionally due to steel strand wires have a preferable bending property, thus side slope occur a certain degree of subside or slide time, Whole device only can bend therewith, will not be broken off, and then enhances the shear behavior of device, improves the effect of slope reinforcement.(see Fig. 3).
