Product Introduction
HFZL30 long screw piling rig is a kind of deep drilling long screw drilling rig newly developed by our company.
The pile frame of this drilling rig adopts a boat-shaped track, crawler walking, flexible displacement and convenient in place.The drilling rig adopts electro-hydraulic centralized control, which is easy to operate, and the three-point support column can be adjusted before and after or left and right. The whole machine can achieve 360°. Total revolution.
The drilling tool part adopts a three-ring reducer as the power, and the key flange is used as the drill pipe, which is safe and reliable, and the disassembly is quick. The drilling rig can adopt superfluid, high-pressure mud injection, dry hole formation and other construction technologies; The pile support can use a vibratory hammer below 120kw.
It can realize the construction of prefabricated piles, concrete cast-in-place piles, concrete garlic piles, lime piles, gravel piles, etc.
Product Advantages
HFZL30 hydraulic crawler bored pile construction, high hole forming efficiency, good quality, no impact, noise or pollution, high degree of mechanization;
At the same time, the performance of drilling into the gravel layer is better than that of the hammering method and the pile sinking method, and the adverse effects of hammering and vibrating pile sinking on the foundation are avoided.
Product Applications
HFZL30 hydraulic crawler bored pile construction, as an environmentally friendly piling machinery product suitable for urban construction, the drilling rig is widely used in pile foundation construction of industrial and civil buildings.
