Abstract
The utility model relates to a self-drilling slurry filling type anchoring-bolt system. The utility model is characterized in that the front end of an anchoring-bolt in an anchoring section is connected with a drill head, and a plug-hole device is arranged between the anchoring-bolt in the anchoring section and the anchoring-bolt in a free section. The anchoring-bolts in the various sections are connected with connectors, and the end of the anchoring-bolt in the free section is provided with a resilient tie plate locked with screw nuts. The utility model has the advantages that hole-forming, slurry filling and tensioning of the anchoring-bolt system are completed once, structure is simple, operation is convenient, construction technology process is simplified, construction speed is accelerated, engineering cost is reduced, and engineering quality is improved. The utility model is suitable for various operating conditions.
Description
The utility model relates to pore-forming in a kind of ground anchorage system, slip casting, the one step completed slip casting formula anchor pole system of boring certainly of stretch-draw.
Traditional anchoring system construction technological process probably can be divided into two kinds: a kind of is at geological conditions operating mode preferably.Under this operating mode, adopt rig earlier anchor hole to be got out, extract drilling rod, in anchor pole (or anchor cable) patchhole, carry out slip casting, maintenance, and then the screw end bar of burn-oning (or loading onto the intermediate plate ground tackle), carry out stretch-draw again; Another kind is the operating mode at the geological conditions complexity, as the underground situation that sposh or drift sand formation are arranged, in this case, adopt first kind of job practices just can not pore-forming, must adopt the rig of band sleeve pipe and interior drilling rod, sleeve pipe and interior drilling rod are together pierced, after reaching projected depth, interior drilling rod is extracted, anchor pole (or anchor cable) is inserted in sleeve pipe, slip casting in the past hole, limit, sleeve pipe is extracted on the limit.After all extracting, the maintenance certain hour, the screw end of burn-oning bar (or loading onto the intermediate plate ground tackle) carries out stretch-draw again.These two kinds of construction technologies are complicated, and engineering cost is higher, and particularly second kind of operating mode difficulty is bigger.
The purpose of this utility model just provides a kind of pore-forming, slip casting, stretch-draw and once finishes, and is simple in structure, easy to operate, is applicable to various operating modes, simplify construction technological process, accelerate speed of application, reduce engineering cost, improve the slip casting of brill certainly or the anchor pole system of workmanship.
Solution of the present utility model is such: mainly be made of drill bit, anchoring section anchor pole, free section anchor pole, connector.Front end at the anchoring section anchor pole is connected with drill bit, has aperture on its anchoring section, and each section anchor pole connects with connector, between anchoring section anchor pole and the free section anchor pole plugging device is set, and is provided with the resilient sleeper-bearing of available nut check at free section anchor pole end.During use, earlier the anchoring section anchor pole is connected with drill bit, the other end is connected with the rig head, after first segment pierced the stratum, with second section anchoring section anchor pole on the connector device, creep into again, reach design anchoring section length after, load onto plugging device, be changed to free section anchor pole, so circulation is after reaching design anchoring requirement, load onto elastic plate and locking nut, screw on filling adaptor and Grouting Pipe, toward hole inner high voltage slip casting, slurry oozes out from the anchoring section aperture, the silt particle on anchoring section anchor pole next door squeezed open, form anchoring section preferably, after maintenance a period of time, get final product direct stretch-draw, with nut check, just can once finish pore-forming, slip casting, stretch-draw.
The utility model has the advantages that pore-forming, slip casting, stretch-draw once finishes, simple in structure, easy to operate, be applicable to various operating modes, simplify construction technological process, accelerate speed of application, reduce engineering cost, improve workmanship.
Below in conjunction with accompanying drawing the utility model embodiment is described:
Accompanying drawing 1 is a structural representation.
The utility model includes anchoring section anchor pole 2, the front end of free section anchor pole 4, anchoring section anchor pole 2 is connected with drill bit 1, have aperture on its anchoring section, slip casting can be oozed out from aperture, anchoring section anchor pole 2 is the screw thread seamless pipe with free section anchor pole 4, connect with connector 3, free section anchor pole 4 is provided with the resilient sleeper-bearing 6 of available nut 7 lockings, can be connected with filling adaptor 8, high-pressure slip-casting pipe 9 at an end of free section anchor pole 4.
Drill bit 1 can be the self tapping drill bit, and when being used for lithosphere, drill bit 1 can change drill hammer into.The plugging device 5 that is provided with on free section anchor pole 4 can optionally be selected for use.Free section anchor pole 4 visual engineering designs require with connector 3 splicings.In the present embodiment, anchoring section anchor pole 2 is to adopt special finished screw thread seamless steel pipe with free section anchor pole 4.
Claims (4)
1, a kind of from boring slip casting formula anchor pole system, include anchoring section anchor pole 2, free section anchor pole 4, it is characterized in that the front end of anchoring section anchor pole 2 is connected with drill bit 1, have aperture on its anchoring section; Anchoring section anchor pole 2 is the screw thread seamless pipe with free section anchor pole 4, connects with connector 3.
2, according to claim 1 from boring slip casting formula anchor pole system, it is characterized in that free section anchor pole 4 is provided with the resilient sleeper-bearing 6 of available nut 7 lockings.
3, according to claim 2 from boring slip casting formula anchor pole system, it is characterized in that being provided with plugging device 5 between free section anchor pole 4 and the anchoring section anchor pole 2.
4, according to claim 1 from boring slip casting formula anchor pole system, it is characterized in that drill bit 1 can be a clay self tapping drill bit, also can be the rock impact drill bit.
