Technical field
A kind of civil engineering side slope protection grouted anchor bar of the utility model, when being related to a kind of civil construction, side slope is protected
Cross grouting anchor rod device, belong to field of civil engineering.More particularly to a kind of device that can effectively improve side slope protection effect.
Background technology
At present, in work progress, it is often necessary to side slope protection is carried out, but in protection process, it may appear that the soil body caves in
Situation, wet region is more especially being glued for soil property, such as situations such as lakeside, existing grouted anchor bar when in use, by anchor
Bar is squeezed into the soil body, then inwardly carries out slip casting, but the structure of grouted anchor bar is all single hollow tube tubulose, grout outlet side
To single, the matrix formed after slurries injection solidification in the soil body is also more local, and the slurry stream of injected hole goes out without successively
Sequentially, complex grouted anchor bar can start slip casting in side wall, in slurries injection process, flowed out from side wall, form backflow, overflow
Go out the soil body, and during anchor pole is squeezed into, the soil body of sidewall locations is extruded consolidation, and most slurries are difficult outflow so that
The combination of medium position and the soil body is poor, anchor pole occurs and fixes shakiness, protection effect is poor.
The content of the invention
In order to improve the above situation, a kind of civil engineering side slope protection grouted anchor bar of the utility model provides one kind can be effective
Improve the device of side slope protection effect.It is simple in construction, it is convenient and practical.
A kind of civil engineering side slope protection grouted anchor bar of the utility model is realized in：A kind of civil engineering side slope of the utility model

Outside, and one end is hinged with anchor pole head respectively, the multiple extension pawl and magnet are corresponding, and the extension pawl is by metal material system
Into bowl-type lid is placed on the hollow drill pipe other end, and the bowl-type lid is built-in with pulp passage, and is connected with hollow drill pipe, bullet
Property shrouding is placed on bowl-type exterior surface, and the bowl-type, which covers, is provided with multiple root injected holes, and is connected respectively with pulp passage
It is logical.
In use, needing the place punching of supporting first, then hollow drill pipe is put into hole, until earth's surface pressure ring pressure
On the ground, the fixation latch on earth's surface pressure ring can be pricked into soil, tentatively fix, then can screw clamp nut,
Pressure-bearing sleeve is compacted during precession, and hollow drill pipe stress is pulled outward, and hollow drill pipe drives limiting stand movement, and passes through
Threaded connecting sleeve drives the movement of anchor pole head, and anchor pole head drives multiple extension pawl movements, when multiple extension pawls touch outer tube,
With movement, outer tube struts multiple extension pawls, so as to which multiple extension pawls are deeply pricked into drill hole inner wall, makes hollow drill pipe very
Good and drill hole inner wall combines, and improves its supporting effect, when limiting stand is moved to spacing ring position, hollow drill pipe is limited
Position, prevents hollow drill pipe from continuing to move to, the hinged place of hollow drill pipe and clamp nut is damaged, and then opens capping, to
Slip casting in hollow drill pipe, slurries flow downward in hollow drill pipe, and fraction slurries first pass through through hole and flowed into point slurry passage, point slurry
Slurries in passage are flowed out by multiple middle part injected holes, are penetrated into the gap between drill hole inner wall, fraction slurries pass through pulp
Passage flows out, and the slurries in pulp passage press to elastic shrouding, elastic shrouding top are opened, so that multiple root injected holes are beaten
Open, the part slurry in pulp passage is flowed directly out, and remaining slurries is flowed out by multiple root injected holes, and then is deep between hole wall
Gap in, soil matrix is consolidated, the design of the elastic shrouding, root injected hole can be sealed in not slip casting
It is stifled, the design of the magnet, there can be suction to multiple extension pawls, prevent that extending pawl arbitrarily moves, the middle part injected hole,
The design of root injected hole, by increasing capacitance it is possible to increase the passage of slip casting, slurries is penetrated into around hollow drill pipe in the hole wall of all directions,
Solidified, even and if the slurry outlet of side block, nor affect on slip casting, the design of the fixed latch, Neng Gouzha
Enter in soil, hollow drill pipe is fixed, further improves protection effect, is reached in civil construction, side slope is protected
Purpose.
Beneficial effect.
First, it is simple in construction, it is convenient and practical.
2nd, cost is cheap, easy to spread.
3rd, side slope protection effect can be effectively improved.
