Problems solved by technology

However, due to the different geology of the rock formations to be drilled, the pile hole walls that have been drilled are prone to collapse during the process of lifting the hammer chisel mechanism, resulting in poor drilling quality and low efficiency
In order to avoid the collapse of the pile hole

Abstract

The invention discloses equipment for one-time pile forming into rock of a screw pile driver and a pile forming method. The method employs the screw pile driver to realize pile forming into rock on a subgrade, and specifically comprises the steps of assembling and positioning the screw pile driver, drilling down into the ground to form a pile hole, lifting a drill, injecting concrete into the pile hole and placing a steel reinforcement cage. With the equipment and the pile forming method provided by the invention, drilling, pouring and pile forming can be completed in one step, the process steps of pile forming are simplified, the investment of manpower and material resources is saved and the production cost is reduced. Besides, the quality of drilling and pile forming is improved, and the working efficiency can be improved by 5-8 times in contrast with traditional process.

Description

technical field [0001] The invention relates to the technical field of engineering construction, in particular to a method for forming piles into rock by using a screw pile machine. Background technique [0002] At present, geotechnical drilling engineering has occupied an increasingly important position in my country's economic construction. Its application fields not only involve mineral exploration and development, but also more and more involve construction, water supply, municipal administration, transportation and environment, etc. . With the further acceleration of the pace of my country's economic construction, the market for such projects is getting bigger and bigger, and the requirements are getting higher and higher. Pneumatic down-the-hole hammer drilling technology has become one of the symbols to measure the level of drilling technology because it can greatly improve drilling efficiency, ensure project quality, reduce construction costs, and have significant tec...
