Description
Technical field
The utility model is related to a kind of anti-slip grouted anchor bar.
Background technology
At present in mine timbering, roads and tunnels supporting, grouted anchor bar supporting has become a kind of conventional supporting
Mode, but in weak stratum, supporting anchor pole at initial stage easily slides, slip casting is uneven to be led to not play effective anchoring work
With.
Utility model content
The purpose of this utility model is to overcome the weak point of prior art there is provided a kind of anti-slip grouted anchor bar.
To achieve the above object, the utility model is achieved through the following technical solutions：
A kind of anti-slip grouted anchor bar, including anchor pole shell, anchor pole shell inwall have screw thread, two sections of spirals, screw-thread steel
There is defeated slurry hole, by being threaded into anchor pole shell, be connected in using bamboo trunk with spring on anchor pole shell in muscle, bamboo trunk connects with anchor pole shell phase
Connect, help to prevent that anchor pole from sliding and slip casting is uniform, lever front end is provided with feed pipe for mortar, and stop grouting plug is provided with anchor rod body,
Stop grouting plug is provided with steam vent.
Described bamboo trunk is in hollow circular cylinder, and external diameter 5mm, internal diameter 1mm, long 10cm have 4.
Therefore, the beneficial effects of the utility model are：Using the utility model, contribute to slip casting uniform, spring connection bamboo
Pipe, can prevent anchor pole from sliding.The crotch grouted anchor bar is simple in construction, with low cost, can effectively solve the phase in background technology
Pass problem.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure, 1. anchor pole shell, 2. bamboo trunk, 3. spring, 4. stop grouting plug, 5. spiral, 6. cavity, 7. steam vents 8. are defeated
Slurry pipe.
Embodiment
In order that the technical characteristic that the utility model is realized is apparent to reached purpose, below in conjunction with the accompanying drawings, further
Illustrate the utility model.
As shown in figure 1, a kind of anti-slip grouted anchor bar, including anchor pole shell 1, two sections of spirals 5 are by being threaded into anchor
In bar shell 1, centre, which is left, defeated slurry hole in cavity 6, spiral 5, is connected in using 4 bamboo trunks 2 with spring 3 on anchor pole shell 1, bamboo
Pipe 2 is connected with anchor pole shell 1, and body of rod leading portion is provided with feed pipe for mortar 8, and stop grouting plug 4 is provided with anchor rod body, and stop grouting plug 4 is provided with
Steam vent 7, slurries are flowed into from feed pipe for mortar 8, are flowed out by pore into cavity 6 from bamboo trunk 2, and spring 3 causes bamboo trunk 2 opens to prevent
Anchor pole slides.
