TL;DR: In this paper, a high-frequency vibration-punching base expansion grouting pipe pile and a construction method of the highfrequency vibration punching and static pressing are presented, and the construction method comprises the steps that hammering and static press are carried out on the pipe pile according to the design requirements so that the pipe-p body can have the designed elevation.

TL;DR: In this article, a dynamic compaction vibration compound baseexpanded pile machine is characterized in that a vibratory hammer is sleeved on the top position of the outer pipe and a diesel hammer is arranged on a flange plate at the top of the inner pipe.

TL;DR: In this paper, a full-hydraulic static-pressure dual-pipe composite expanded bore pile machine is described, and a construction method for its construction is presented. But the work is limited to the case of a single machine.

Abstract: The utility model discloses a double -barrelled compound club -footed pile of all -hydraulic static pressure machine, it is double -barrelled with the complex of hoisting in pressing from both sides the stake system including pressing from both sides the stake system, it is compound double -barrelled including inner tube and outer tube, the inner tube suit is inside the outer tube to including outer tube upper portion adopt coupling device fixed, press from both sides the stake system can by last press from both sides the stake case and press from both sides a stake case down constitute, two upper and lower cartridge clip stake case effective stroke 3 -5 rice press from both sides a stake clamp down and hold the outer tube, but go up and press from both sides stake case not only a centre gripping outer tube but also centre gripping inner tube, utilize the inner tube to exert pressure to form and expand end effect. Perhaps press from both sides a stake system and include that presss from both sides a stake case down, press from both sides the double -layereds pipe holder that stake case upper portion was provided with a clear height 2 rice down, press a stake stroke to be 3 -4 rice, be provided with roof pressure crossbeam system on the clamp pipe holder, roof pressure crossbeam system is the roof pressure inner tube above the inner tube, roof pressure crossbeam system is the back pressure inner tube above the inner tube, forms to expand end effect. The utility model relates to a friction, noiselessness, contamination free construction machinery and construction technology.
