Detailed Description
The following description refers to the accompanying drawings for a concrete implementation method of the vertical shaft soil body reinforcing anchor rod and the construction method thereof.
As shown in fig. 1 to 5, according to the utility model discloses a vertical shaft soil body reinforcement stock of embodiment, including double thread sleeve 1, the reinforcement body of rod 2, extension bolt 3, ejector pin 4. The interior of the double-thread sleeve 1 is of a cavity structure, the cavity is used for accommodating a reinforcing rod body 2 and a push rod 4, the front end of the double-thread sleeve 1 is provided with three reserved ports 5, slurry can overflow through the reserved ports 5 in the grouting process, the top end of the reinforcing rod body 2 is provided with three reinforcing pieces 6, barbs 7 are arranged on the reinforcing pieces 6, the lengthening bolts 3 and the push rod 4 are of a combined structure, the lengthening bolts 3 rotate to enter the push rod 4 through holes in the end face of the push rod 4, the lengthening bolts 3 penetrate through the push rod 4, the reinforcing rod body 2 can freely slide in the cavity of the double-thread sleeve 1, the push rod 4 is in threaded connection with the inner cavity of the double-thread sleeve 1, nuts 10 at the tail part of the push rod 4 enable the combined structure formed by the lengthening bolts 3 and the push rod 4 to rotate in the cavity, the heads of the lengthening bolts 3 abut against positioning grooves 8 of the reinforcing rod body 2 in the advancing process, so that the reinforcing rod body 2 slides in the cavity under the action of pushing force, piece 6 is strengthened in the drive and is expanded through reserving mouthful 5, later against revolve extension bolt 3 take it out, carries out the slip casting through the through-hole of ejector pin 4, and the slurry passes through positioning groove 8's through-hole and consolidates the gap between the body of rod 2 and the double thread sleeve 1 and follow it is spilled over to strengthen piece 6 and the clearance of reserving mouthful 5 formation, treats the preliminary back that solidifies of slurry, and rotatory double thread sleeve 1 afterbody nut 11 drives the stock and wholly tightens up, strengthens piece 6 and the abundant contact of slurry, makes barb 7 lifting surface area bigger, has improved the withdrawal resistance of stock, and the reinforcement piece pierces the anchor body that the soil body formed after slip casting is accomplished and is bigger, and the anchor power is stronger.
Preferably, fixedly connected with stationary blade 9 before 1 surface screw thread of double thread sleeve, stationary blade 9 is oval, and the fixed orifices is reserved on both sides, for preventing rotatory 1 afterbody nut of double thread sleeve 11 in-process from driving the stock whole and rotate, fixed stationary blade 9 makes double thread sleeve 1 can not take place relative rotation to the reinforced soil body, places seal gasket 12 before nut 11.
