Abstract
The utility model relates to a self-propelling grouting anchor bolt. An anchor bolt body 1 is a hollow tube, a drill 2 is connected with the front end of the anchor bolt body and a shim plate 3 and a retaining nut 4 are arranged at the back end of the anchor bolt body. A slurry outlet of the drill 2 is communicated with a cavity of the anchor bolt body 1, a grouting hole 5 is formed on the anchor bolt body 1 and is communicated with the cavity of the anchor bolt body 1 and the grouting hole 5 is sheathed with a grouting ring 6. The grouting hole 5 can be open under definite grouting pressure in order to protect the grouting satiation of full anchor holes to form a columnar concrete diffuser.
Description
The utility model is relevant with anchor pole, and is especially relevant with the grouted anchor bar of band drill bit.
Traditional self-advancing type grouted anchor bar is a hollow tube.The drill bit that connects on the anchor pole head has grout outlet to communicate with hollow tube.When creeping into, water is flowed out by hollow tube to grout outlet, and during grouting, slurry can only flow out from the grout outlet of drill bit, and slip casting efficient is not high, and grouting quality is not high.
The purpose of this utility model provides a kind of simple in structure, slip casting efficient height, the self-advancing type grouted anchor bar that grouting quality is good.
Anchor bar body 1 of the present utility model is a hollow tube, and front end is connected with drill bit 2, backing plate 3 and clamp nut 4 are equipped with in the rear end.The grout outlet of drill bit 2 communicates with the cavity of anchor bar body 1.Injected hole 5 is arranged on the anchor bar body 1.Injected hole 5 is with slip casting ring 6.
Injected hole of the present utility model can be more than 1.
Stop grouting plug 7 is arranged on the anchor bar body of the present utility model.The hole of stop grouting plug 7 and anchor bar body have clamp nut movingly.
Injected hole on the utility model anchor bar body by the slip casting ring seal, can guarantee creeping into and water filling of self-feeding anchor pile under low pressure conditions.Under certain grouting pressure condition, injected hole can be opened automatically, to guarantee that full anchor hole slip casting is full and to form column concrete diffuser.Stop grouting plug 7 is easy for installation, can not cause the obstruction of injected hole because of installation procedure.Grouting quality is good, the efficient height.
Fig. 1 is a front view of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is embodiment 2 front views.
Following is embodiment of the present utility model:
Embodiment 1:
Anchor bar body 1 front end is threaded with drill bit 2, and backing plate 3 is equipped with in the rear end, and is fastening with nut 4.Anchor bar body 1 hollow is communicated with the slurry outlet of drill bit 2, is communicated with injected hole 5 on the body of rod.The slip casting ring 6 of flexible material such as rubber system on the injected hole 5 outer bodies of rod.Ring 6 has the performance of the distortion of extending to hole 5 sealings under the certain pressure effect.
When creeping into, water can flow out from the drill bit grouting port by the anchor pole 1 of hollow, and can not flow out from injected hole 5, can guarantee normally carrying out of the work of creeping into.When slip casting, under certain grouting pressure, elasticity slip casting ring 6 is by distending, and slurry can flow out from injected hole 5, can guarantee that full anchor hole slip casting is full and form column concrete diffuser.
Embodiment 2:
Basic structure is identical with embodiment 1, and just the injected hole 5 on the anchor bar body 1 is 3, directly seals by rubber plantation shape closing cap 10 and hole wall tight fit.Under the pressure of water, closing cap can seal, and under grouting pressure, closing cap is washed open, and slurry is flowed out by injected hole 5.
On anchor bar body, there is screw thread to cooperate with nut 8,9.Screw in earlier nut 8 during slip casting to design attitude, putting into stop grouting plug 7, stop grouting plug and anchor bar body 1 movingly, fastening nut 9 makes it fastening again, what can effectively prevent to starch leaks, and assembles very conveniently, laborsaving, can not stop up injected hole.
