Abstract
The utility model discloses a take skeleton to expand body stock, use in the stock rear end that a slip casting pipe is installed to the clamp and a row starches the pipe, the face down is connected with a steel cylinder under the last clamp of stock, be equipped with on the circumference wall of steel cylinder and upwards seal downward open -ended intermediate layer passageway, install a telescopic piston at the steel cylinder lower extreme, sliding fit is sealed about first one of piston inserts in the intermediate layer passageway, install the fixed loop on protect the lower clamp of first end, at the upper end of fixed loop and lower extreme along the peripheral round pin axle of installing eight equipartitions respectively of piston, but move the guiding orientation frame that stretches out from top to bottom respectively selling epaxial and install an outside yaw of 90o respectively, , each that corresponds from top to bottom install a hole enlargement pole with the round pin hub connection respectively between putting up guiding orientation, install one and the communicating tee bend of steel cylinder intermediate layer passageway below the clamp on slip casting guan shangyu. The withdrawal resistance can reach between 600-1200KN.
Description
Technical field:
The band skeleton enlarging anchor rod that the utility model uses when being a kind of heavy construction ground stabilization.
Background technology:
The two bellows enlarging anchor rod of existing integration, on the anchor pole that a front end is provided with location head protector, a pouch is fixed by a pair crimp respectively in two ends, pouch diameter on the head protector end body of rod and length are all greater than the sealing of hole pouch of the other end, while be provided with a Grouting Pipe on dop outside the crimp of sealing of hole pouch two ends, another side is provided with a discharge pipe, in Grouting Pipe with in expansion somatocyst bag, an explosive valve is installed, discharge pipe is provided with an isolated trap valve of aqueous vapor between two pouches, Grouting Pipe in sealing of hole pouch is provided with unidirectional grout valve.Two pouches are all make with the anticorrosion cloth of counter-infiltration.Although this structure improves resistance to plucking dynamics and the sealing quality of anchoring body, find in practice process, its uplift resistance is maximum is no more than 600KN, can't be suitable for uplift resistance and use more than the heavy construction ground stabilization of more than 600KN.
Summary of the invention:
The purpose of this utility model is to provide the band skeleton enlarging anchor rod applied widely between 600 ~ 1200KN of uplift resistance after a kind of anchoring.
The technical solution of the utility model completes as follows, a kind of band skeleton enlarging anchor rod, it comprises the anchor pole that a front end is provided with location head protector, at anchor pole rear end front band, a Grouting Pipe and a discharge pipe are installed, it is characterized in that: face down under the front band of anchor pole and be connected with a steel cylinder, the circumferential wall of steel cylinder is provided with the sandwich passage upwards closed under shed, a telescopic piston is installed in steel cylinder lower end, the first half of piston slides up and down fitted seal and is inserted in sandwich passage, on the lower catch hoop of head protector one end, retainer ring is installed, eight uniform bearing pins are separately installed with at the lower end edge periphery of the upper end of retainer ring and piston, each bearing pin is up and down separately installed with one and can laterally rotates the guide-localization frame stretched out by 90o, between each pair of corresponding up and down guide-localization frame, with pinned connection, an expanding bar is installed respectively, in Grouting Pipe with a threeway communicated with steel cylinder sandwich passage is installed below front band.Lower catch hoop with below pistons stops between two pressure ring be provided with one the aqueous vapor that guide-localization frame and expanding bar are placed in chamber be separated pouch.
The utility model expands body skeleton makes anchoring body shape normalised, not only remain the advantage of prior art, and uplift resistance can reach between 600 ~ 1200KN, not be only applicable to husky ovum stratum, be also applicable to clay stratum.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model; Fig. 2 is the structural representation of the utility model expanding bar when opening; Fig. 3 is the A-A sectional view of Fig. 1; Fig. 4 is the B-B sectional view of Fig. 1; Fig. 5 is that the utility model is provided with the structural representation of expansion somatocyst bag when expanding bar opens.
Detailed description of the invention:
Describe embodiment in detail by reference to the accompanying drawings, it comprises the anchor pole 1 that a front end is provided with location head protector 15, at anchor pole rear end front band 3, a Grouting Pipe 2 and a discharge pipe 16 are installed, main improvements face down for 3 times at the front band of anchor pole to be connected with a steel cylinder 5, the circumferential wall of steel cylinder is provided with the sandwich passage upwards closed under shed, a telescopic piston 6 is installed in steel cylinder lower end, the first half of piston slides up and down fitted seal and is inserted in sandwich passage, on the lower catch hoop 14 of head protector one end, retainer ring 13 is installed, eight uniform bearing pins 7 are separately installed with at the lower end edge periphery of the upper end of retainer ring and piston, each bearing pin is up and down separately installed with one and can laterally rotates the guide-localization frame 8 and 12 stretched out by 90o, between each pair of corresponding up and down guide-localization frame, with pinned connection, an expanding bar 9 is installed respectively, in Grouting Pipe with a threeway 4 communicated with steel cylinder sandwich passage is installed below front band.Lower catch hoop with below pistons stops between two pressure ring be provided with one the aqueous vapor that guide-localization frame and expanding bar are placed in chamber be separated pouch 10.During use, the invention of this reality is sent in stratum by boring, connect Grouting Pipe, first by threeway, high pressure slurries are advanced in the sandwich passage of copper cylinder, piston is forced to move downward, be that 90o is extrapolated shaping each upper and lower guide-localization frame, after slip casting reaches certain pressure, slip casting one way valve 11 is opened, start slip casting in expansion body cavity or pouch, till filling.A kind of standardized anchoring body can be become after solidifying.
Claims (2)
1. a band skeleton enlarging anchor rod, it comprises the anchor pole that a front end is provided with location head protector, at anchor pole rear end front band, a Grouting Pipe and a discharge pipe are installed, it is characterized in that: face down under the front band of anchor pole and be connected with a steel cylinder, the circumferential wall of steel cylinder is provided with the sandwich passage upwards closed under shed, a telescopic piston is installed in steel cylinder lower end, the first half of piston slides up and down fitted seal and is inserted in sandwich passage, on the lower catch hoop of head protector one end, retainer ring is installed, eight uniform bearing pins are separately installed with at the lower end edge periphery of the upper end of retainer ring and piston, each bearing pin is up and down separately installed with one and can laterally rotates the guide-localization frame stretched out by 90o, between each pair of corresponding up and down guide-localization frame, with pinned connection, an expanding bar is installed respectively, in Grouting Pipe with a threeway communicated with steel cylinder sandwich passage is installed below front band.
