The utility model discloses simple structure can improve the effect of filling of cement thick liquid.
Description
Technical Field
The utility model relates to an anchor rod that can be used to pour into cement thick liquid.
Background
The stock reinforcement is a supporting technology that is used for carrying out the reinforcement to the foundation ditch rock mass, and the stock reinforcement technique is through driling at the rock mass surface, then inserts the stock into rock mass drilling and pours into the cement thick liquid between stock and drilling inner wall and realize the anchor of stock, in order to improve the anchor effect, generally need require to be full of the cement thick liquid in drilling, prevents the cavity. However, the traditional anchor rod generally adopts a solid structure, cement grout needs to slowly flow into the deep part of a drill hole along the opening of the drill hole in the pouring process, the construction is slow, and the cement grout is easy to coagulate in the flowing process, so that the flowing effect is weakened.
SUMMERY OF THE UTILITY MODEL
The utility model provides a not enough to prior art, the utility model provides a can be used to fill stock of cement thick liquid, its simple structure can improve the effect of filling of cement thick liquid.
In order to realize the above-mentioned purpose, the utility model provides an anchor rod that can be used to pour cement thick liquid, including the body of rod that cavity set up and the ejector pin of setting at body of rod front end, the rear end activity of ejector pin sets up in the hole of the body of rod and can be in the regulation stroke along body of rod fore-and-aft direction motion, the rear end of ejector pin has a notch that is connected with body of rod hole, and the notch lateral wall is provided with first grout outlet, body of rod lateral wall is provided with the second grout outlet of intercommunication inside and outside, works as when the ejector pin moves backward on earth the second grout outlet is in with first grout outlet and aligns the connected state.
The utility model has the advantages that: during the construction, pour into the cement thick liquid along body of rod rear end hole, then stretch into the drilling with the stock, when stretching into the drilling bottom, the ejector pin is driven backward motion and makes first grout outlet and second grout outlet align, and the cement thick liquid in the body of rod hole can be followed grout outlet and outwards flowed to fill up whole drilling gradually. Compared with the prior art, the utility model, because directly begin going on in the drilling bottom when pouring the cement thick liquid, be difficult to appear the cavity in the drilling when solidifying, can improve the anchor effect, on the other hand just can begin the slip casting when the stock inserts the drilling bottom because the setting up of ejector pin makes, can further improve the effect of pouring of cement thick liquid.
Furthermore, at least one guide groove is uniformly distributed in the circumferential direction of the rod body, the length direction of the guide groove and the motion direction of the ejector rod are on the same straight line, and the ejector rod comprises a guide block which is matched with the guide groove and slides forwards and backwards.
The further setting has the advantages that: the cooperation of guide way and guide block can restrict the direction of motion of ejector pin, can prevent that the ejector pin from droing from the body of rod, also can improve the alignment effect in first grout outlet and second grout outlet to improve the outflow effect of cement thick liquid.
Furthermore, a spring for driving the ejector rod to move forwards in a reset mode is arranged between the ejector rod and the rod body.
The further setting has the advantages that: the ejector rod is kept in the position moving to the most front end, so that the slurry can be prevented from being discharged when the anchor rod is not inserted to the bottom of the drill hole.

Detailed Description
The embodiment of the anchor rod used for pouring cement grout of the utility model is shown in figures 1-2: including the body of rod 1 that cavity set up and set up the ejector pin 2 at the 1 front end of the body of rod, the rear end activity of ejector pin 2 sets up in the hole 11 of the body of rod 1 and can be in the regulation stroke along the motion of the 1 preceding back direction of the body of rod, the rear end of ejector pin 2 has a notch 21 that is connected with body of rod hole 11, and notch 21 lateral wall is provided with a plurality of first grout outlet 22, and 2 circumference equipartitions of ejector pin are followed to a plurality of first grout outlet 22, body of rod 1 lateral wall is provided with a plurality of second grout outlet 12 of intercommunication inside and outside, and the second grout outlet 12 is along 1 circumference equipartition of the body of rod, works as when 2 is moving backward to the end the ejector pin 2 a plurality of second grout outlet 12 and a plurality of first grout outlet 22 are in the one-to-one alignment intercommunication state.
In order to prevent that ejector pin 2 from deviating from the body of rod 1 and guarantee the alignment effect of first play thick liquid hole 22 and second play thick liquid hole 12, the circumference equipartition all around of the body of rod 1 has at least one guide way 13, the length direction of guide way 13 is in on the same straight line with the direction of motion of ejector pin 2, ejector pin 2 including with gliding guide block 23 around the guide way 13 cooperation, the direction cooperation through guide block 23 and guide way 13 can prevent ejector pin 2 and the body of rod 1 circumferential direction to can restrict the seesaw stroke of ejector pin 2.
When cement grout is injected into and fills the inner hole of the rod body 1, pressure can be applied to the ejector rod 2 to move forwards, but in order to improve the effect of the forward movement of the ejector rod 2, a spring for driving the ejector rod 2 to reset forwards is arranged between the ejector rod 2 and the rod body 1 in other embodiments, and the spring can be sleeved on the part of the ejector rod 2 extending out of the front end of the rod body 1 and can respectively abut against the front end of the ejector rod 2 and the front end of the rod body 1.
The above embodiment is only one of the preferred embodiments of the present invention, and the general changes and substitutions performed by those skilled in the art within the technical scope of the present invention are included in the protection scope of the present invention.
