Abstract
The utility model relates to a self-drilling grouting bolt, which comprises a stop plug with stomata, a pad, nuts, and hollow thread tubes, which is characterized in that a bit is available on the front end of the hollow thread tube in which the back end is linked to a back hollow thread tube through a connecting sleeve. The back hollow thread tube is provided with a stop plug, and the hollow thread tube end is provided with a pad and nuts. The connecting sleeve is provided with an inner tube connected to the hollow thread tube through a through hole. More than one connecting sleeves and back connected hollow thread tubes can be provided. The advantages of the utility model are that the grouting bolt can be applied to the fixation of the building foundation with the loose geological structure.
Description
Technical field
The utility model relates to a kind of grouted anchor bar, particularly a kind of self-drilling grouted anchor bar.
Background technology
On building site, heavy construction basis, often adopt grouted anchor bar to come massif slope or tunnel wall are reinforced at present, after boring on the bodies that are fixed such as massif slope or tunnel wall, grouted anchor bar is inserted in the hole, screwed pipe by hollow grout injection inward then, cement paste curing back is about to the massif slope or tunnel wall is fixed, but when running into some special soft geologies structures, after the drilling rod that is used for holing is extracted, boring is promptly filled out again by the grit that is scattered in the boring, grouted anchor bar is just inserted less than in the boring, therefore existing common grouted anchor bar can't use in the soft geology structure, cause the building foundation engineering constructional difficulties, need utilize other construction means to finish.
Summary of the invention
The purpose of this utility model is to solve the problems referred to above that grouted anchor bar can't use when soft geology is constructed in the prior art, and a kind of self-drilling grouted anchor bar that is suitable for the soft geology structure is provided.The utility model design self-drilling grouted anchor bar, comprise stop grouting plug, backing plate, nut, the cannulated threaded pipe of being with pore, it is characterized in that: the front end of cannulated threaded pipe has a drill bit, rear end at the cannulated threaded pipe connects back one cannulated threaded pipe by adapter sleeve, on the one cannulated threaded pipe of back, stop grouting plug is arranged, the end of cannulated threaded pipe has backing plate and nut, has through hole to connect the interior pipe of cannulated threaded pipe on adapter sleeve.Adapter sleeve and follow-up cannulated threaded pipe can have more than one.The utility model has the advantages that grouted anchor bar can be applicable to building foundation fixing of soft geology structure.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated,
Accompanying drawing is a structural representation of the present utility model,
The specific embodiment
Comprise stop grouting plug 1, backing plate 2, nut 3, the cannulated threaded pipe 4 of being with pore among the figure, it is characterized in that: the front end of cannulated threaded pipe 4 has a drill bit 5, rear end at cannulated threaded pipe 4 connects back one cannulated threaded pipe 4 by adapter sleeve 6, on the one cannulated threaded pipe 4 of back, stop grouting plug 1 is arranged, the end of cannulated threaded pipe 4 has backing plate 2 and nut 3, has through hole 7 to connect the interior pipe 8 of cannulated threaded pipe 4 on adapter sleeve 6.Adapter sleeve 6 and follow-up cannulated threaded pipe 4 can have more than one.In the soft geology techonosphere that directly utilizes rig to be drilled into the self-drilling grouted anchor bar during use to be fixed, then slurry casting machine is twisted and be connected on the cannulated threaded pipe 4 that exposes, with compression pump cement is injected in the hole, cement paste is entered by the interior pipe 8 of cannulated threaded pipe 4, through hole 7 from the adapter sleeve 6 that is arranged in the soft geology structure gets out again, then from the past both sides slip casting simultaneously of the middle part of boring, air in the hole is discharged by the pore on the stop grouting plug 1, because self-drilling slip casting anchor need not be extracted after piercing, can prevent that the grit that the boring of special soft geology structure is scattered from filling out again, also shorten the time of construction simultaneously greatly.
Claims (2)
1, self-drilling grouted anchor bar, the screwed pipe that comprises the stop grouting plug of being with pore, backing plate, nut, hollow, it is characterized in that: the front end of cannulated threaded pipe has a drill bit, the screwed pipe that connects back one hollow in the rear end of cannulated threaded pipe by adapter sleeve, on the one cannulated threaded pipe of back, stop grouting plug is arranged, the end of cannulated threaded pipe has backing plate and nut, has through hole to connect the interior pipe of cannulated threaded pipe on adapter sleeve.
2, by the described self-drilling grouted anchor bar of claim 1, it is characterized in that: adapter sleeve and follow-up cannulated threaded pipe can have more than one.
