The specific embodiment
Below, with reference to the accompanying drawing that can implement specific implementations of the present utility model, describe the utility model in detail.At this, understand these embodiments described later in detail, make those of ordinary skills can implement the utility model fully.The same embodiment of given shape, structure and characteristic in this record is associated, but under the prerequisite that does not break away from technological thought of the present utility model and category thereof, can show as another embodiment.In addition, the position or the configuration of the indivedual inscapes in each embodiment disclosed herein can be understood as under the prerequisite that does not break away from technological thought of the present utility model and category thereof and can change.Therefore, detailed description described later is not to be used to limit the utility model, and protection domain of the present utility model is by the technical scheme of claims record and the technical scheme decision that is equal to it.
Fig. 3 is the schematic diagram that expression is used in bolthole injecting the bolthole grouting device that the utility model of mortar relates to.As shown in the drawing, the bolthole grouting device that the utility model relates to have diameter less than bolthole 10 so that insert Grouting Pipe 301 in the bolthole 10, one end of Grouting Pipe 301 is inserted in the bolthole 10, the other end of Grouting Pipe 301 is connecting the feed pipe for mortar 302 of carrying mortar by Grouting Pipe gate valve 303, the end away from Grouting Pipe 301 at feed pipe for mortar 302 is connecting slip casting jar 304 and airduct 305, slip casting jar 304 is used for providing the mortar that injects usefulness to Grouting Pipe 301, and airduct 305 is used to provide the wind-force that transports mortar.
In addition, this bolthole grouting device also comprises the have certain-length stopple 307 of truncated conical shape of (for example 50mm), the diameter of the smaller diameter end of this stopple 307 is slightly less than the diameter of bolthole 10, for example than the little 4mm of diameter of bolthole, the slightly larger in diameter of the larger diameter end of this stopple 307 is in the diameter of bolthole 10, for example, like this, utilize this stopple 307 can in the slip casting process, stop up bolthole 10 than the big 4mm of injected hole diameter of anchor pole.Offer 2 through holes on this stopple 307, the diameter of one of them through hole is equivalent to the external diameter of Grouting Pipe 301, and Grouting Pipe 301 is therefrom passed, and another through hole is used to pass auxiliary tube 306.The diameter of this auxiliary tube 306 is less than the diameter of bolthole 10, and it can be steel pipe, pvc pipe etc., and it has the length of the Kongzui inboard that is enough to be deep into bolthole 10.One end of this auxiliary tube 306 passes after the through hole of above-mentioned stopple 301, is inserted in the bolthole 10, and is deep near the bolthole end, for example apart from the position of the inboard 50mm of the Kongzui of bolthole 10.Grouting Pipe 301 and auxiliary tube 306 pass above-mentioned stopple 307, and fixedly connected with this stopple 307 by dismountable mode.
In addition, the other end at this auxiliary tube 306 is connecting the feed pipe 311 and the gas vent 309 that discharges water, between the above-mentioned other end of this auxiliary tube 306 and feed pipe 311, be provided with the feed water valve 310 that control is supplied water, control the blow off valve 308 that discharges water and exit with discharging water to be provided with between the gas vent 309 at the above-mentioned other end of this auxiliary tube 306.When opening feed water valve 310, when closing blow off valve 308 simultaneously, supplying water in bolthole 10 by auxiliary tube 306, can require to clean the inside of bolthole 10 thus according to construction reference from feed pipe 311.When closing feed water valve 310, when opening blow off valve 308 simultaneously, can discharging the water and air in the bolthole 10.
Below, utilize aforesaid bolthole grouting device to realize the step of full bolthole mortar depositing construction in conjunction with Fig. 3 explanation.
At first, based on the length dimension and the diameter of anchor pole, for example getting out corresponding bolthole 10 in the lithosphere.
Secondly, with reference to the degree of depth of bolthole 10, Grouting Pipe 301 and auxiliary tube 306 are passed two through holes being located on the stopple 307.Grout outlet one end that makes Grouting Pipe 301 is 307 nearer from stopple, for example apart from the position of 30mm, make auxiliary tube 306 can be deep near position bolthole 10 the most inboard, for example apart from the position of the most inboard 50-100mm of bolthole 10.Afterwards, Grouting Pipe 301 and auxiliary tube 306 are fixed on the stopple 307, and are inserted in the bolthole 10, block bolthole 10 by stopple 307 simultaneously.
Then, under the state of closing its valve 309 that discharges water, open feed water valve 310 and supply water to auxiliary tube 306, water can flow in the bolthole 10, and bolthole 10 is cleaned.Clean after the end, close feed water valve 310, open the vent valve that discharges water, open Grouting Pipe gate valve 303 then and carry out the mortar injection.When carrying out slip casting, mortar injects bolthole 10 from the Grouting Pipe 301 that is positioned at lower, and progressively rises, so the water and air in the bolthole 10 is squeezed and rising synchronously, finally flow in the auxiliary tube 306, is discharged from from outlet opening 308.At last, when occurring returning slurry, show that mortar is injected in the bolthole 10 fully, slip casting is full, so close Grouting Pipe gate valve 303, finishes the slip casting operation.
Finish from bolthole 10, slowly and evenly to extract Grouting Pipe 301 and auxiliary tube 306 after the slip casting, and then slowly and evenly insert predetermined anchor pole, can finish the construction of total length adhesion type anchor pole.The grouting device of extracting can continue on for the slip casting operation of next bolthole.
By using aforesaid bolthole grouting device, owing to be provided with auxiliary tube separately, not only can carry out preceding cleaning of slip casting of bolthole, can also carry out mortar injection from bottom to top by the water and air in this auxiliary tube discharge bolthole.And, when occurring returning slurry, show that the mortar injection in the bolthole is full, therefore, can realize reliable and full slip casting.
In addition, because the diameter of auxiliary tube less than bolt diameter, can guarantee that also the mortar in the bolthole is full after inserting anchor pole.So just can guarantee that the mortar injection in the bolthole is full, can when grouting rock bolt is checked and accepted, obtain very high qualification rate, make because of identifying that afterwards the defective processing of carrying out of doing over again becomes the quality of prior control grouting rock bolt.
