A single-hole compound anchor pile, belongs to the architectural engineering. Useig in the highway subgrade, the bridge ground, the building ground foundation reinforcement. Compound anchor pile including drill hole (1), thick liquid tube (2), sleeve valve tube (3), anchor rod body (4), note hydromass (5); And the sleeve valve tube (3) stops the thick liquid piston by the sleeve valve tube (6), the sleeve valve tube shoots the thick liquid hole (7), the sleeve valve tube floral tube (8), the rubber cup (9); In the implements process first to use the hole machinery to form the drill hole to the single-hole compound anchor pile designed depth, the insertion note thick liquid tube, the sleeve valve tube as well as the anchor rod body, pours the thick liquid tube and the sleeve valve tube length with the hole depth, implements thick liquid first using the note thick liquid tube, after size prehardening, implements two time mesohigh note thick liquid using the sleeve valve tube, two mesohigh note thick liquid pressure is 1-5MPa, pours the thick liquid current capacity is 10-60l/min. The merit is: The location condition requests lowly, machinery simple economy; The pile hole aperture is small, can arrange the battered pile conveniently, the effective resistance horizontal and the vertical load, the supporting capacity is high, is suitable for each kind of different soil texture.
