Abstract
The utility model is related to a kind of grouted anchor bar of controllable grouting amount.The grouted anchor bar is made up of taper anchor head, block handle, circular pushing cover, sleeve, spring, and sleeve outer wall is in shape of threads, and sleeve inner is hollow, two sleeves are set to keep off handle in sleeve, sleeve keeps off between handle and circular pushing cover and installs a spring, by pressing circular pushing cover, controls the grouting amount of anchor pole.
Description
Technical field
The utility model is related to a kind of grouted anchor bar of controllable grouting amount, it is adaptable to slope retaining, underground engineering, building
Slip casting anchoring in base pit engineering.
Background technology
Anchorage Technology is to improve rock mass engineering project stability and the maximally effective side of the complicated Geotechnical Engineering stable problem of solution
One of method, is widely used in fields such as slope project, underground engineering, building foundation pits.But, in current branch nurse
Cheng Zhong, large-scale wall-rock crack issue handling gets up more complicated, and common bolt can not meet the engineering need of complex geological condition
Ask, this is required using the anchor pole that anchoring ability is strong, cementitiousness is strong.
The content of the invention
The utility model is related to a kind of grouted anchor bar of controllable grouting amount, by taper anchor head, block handle, circular pushing cover,
Sleeve, spring composition, sleeve outer wall is in shape of threads, and sleeve inner is hollow, two sleeves gear handles of setting in sleeve, taper anchor head,
Block handle, circular pushing cover, the material of sleeve are polyester resin and reinforced plastic glass fibre.
As an improvement, spring is arranged between sleeve gear handle and circular pushing cover, by pressing circular pushing cover, make slip casting anchor
Bar stretches, and controls the grouting amount of anchor pole.
As an improvement, setting taper anchor head, taper anchor head is solid construction.
The beneficial effects of the utility model are：The utility model sleeve outer wall is in shape of threads, with preferable AsA -GSH cycle,
Sleeve inner is hollow, being capable of the slip casting into anchor pole；Taper anchor head, block handle, circular pushing cover, the material of sleeve are polyester resin
And reinforced plastic glass fibre, with preferable anticorrosion ability；Set two sleeves to keep off handles in sleeve, place the spring in sleeve gear handle and
Between circular pushing cover, the circular pushing cover of pressing, the slip casting into sleeve；Taper anchor head is set, and taper anchor head is solid construction, Neng Gouji
When block sleeve control injection slurry amount.
Brief description of the drawings
Structural representation when Fig. 1 the utility model is stood；
Structural representation when Fig. 2 the utility model is pressed.
Reference：（1）Taper anchor head,（2）Block handle,（3）Circular pushing cover,（4）Sleeve,（5）Sleeve keeps off handle,（6）Bullet
Spring.
Embodiment
The utility model is further described with reference to the drawings and specific embodiments.
The taper anchor head of the utility model（1）With block handle（2）, circular pushing cover（3）All it is solid construction, sleeve gear handle
（5）With circular pushing cover（3）Between spring is set, the circular pushing cover of pressing（3）, grouted anchor bar can stretch.In use, by grouted anchor bar
Taper anchor head（1）First throw side slope, sleeve into（4）Outer wall is contacted with side slope, sleeve（4）Outer wall is in shape of threads, increase and side slope
The frictional force of contact, anchoring stability is good.After grouted anchor bar throws side slope into, slip casting work is carried out, grouted anchor bar is first stood, makes
Taper anchor head（1）With sleeve（4）Closure, makes slurries from sleeve（4）Grouted anchor bar is injected in inwall.Treat that slurries flow into grouted anchor bar
Bottom, the circular pushing cover of pressing（3）, slurries is injected in country rock, by pressing circular pushing cover（3）, grouted anchor bar is stretched, control
Required grouting amount.
