Barrier clearing and pile forming integrated stirring pile machine and construction method thereof

Abstract

The invention provides a barrier clearing and pile forming integrated stirring pile machine and a construction method thereof. The barrier clearing and pile forming integrated stirring pile machine comprises a pile frame, a bracket, a drill rod, a drill bit, a grouting hole, a material storing tank and a driving device; the bracket is arranged on the pile frame in a hung mode and can slide longitudinally relative to the pile frame, the drill rod and the drill bit are connected to the bottom of the bracket, the grouting hole is formed in the drill bit, the material storing tank is connected with the grouting hole through the interior of the drill rod, and the driving device is used for driving the drill rod and the drill bit to rotate; and a plurality of tungsten steel cutter heads are welded around the drill bit in a surrounding mode. According to the barrier clearing and pile forming integrated stirring pile machine, the multiple tungsten steel cutter heads are welded around the drillbit, the crushing and tunneling ability of the stirring pile machine to barriers is greatly promoted, and the construction process is accelerated; and meanwhile, due to the fact that the tunneling ability is promoted, additional barrier clearing construction is not required, and the cost is saved.

Description

technical field [0001] The invention relates to the technical field of building foundation engineering pile foundations, in particular to an integrated stirring pile machine for removing obstacles and forming piles and a construction method thereof. Background technique [0002] During the construction of pile foundation enclosure in the traditional old city, full-rotary casing drilling rigs are mainly used for obstacle removal. That is, the rotary excavator is first used to clear the obstacles, and then the rotary excavator is used for dry excavation construction. When this method encounters underground obstacles, it is difficult to remove them, and in the later stage of construction, the drill bit is severely worn and the cutting ability is insufficient, which increases the difficulty of drilling. In addition, since it is not equipped with a mud wall, shrinkage cavities are prone to occur when the soil is lifted to a certain depth and unloaded, and the surrounding area co...
