A kind of piling equipment and construction method suitable for desert geological conditions

Abstract

The invention discloses pile driving equipment suitable for desert geological conditions. The pile driving equipment comprises a rack and a drilling machine portion arranged on the rack. A power portion used for driving the drilling machine portion is further arranged on the rack. The drilling machine portion comprises a cylindrical drilling barrel, and the two ends of the drilling barrel are open. A baffle portion capable of being opened and closed is arranged at one end of the drilling barrel. A locating barrel is arranged in the drilling barrel, and a limiting portion used for limiting theposition of the locating barrel is arranged at the other end of the drilling barrel. The invention further discloses a pile driving construction method suitable for the desert geological conditions. The method comprises the following steps that S1, a baffle is closed; S2, the drilling barrel is vertically drilled into the ground by a proper depth; S3, the baffle is opened; S4, the locating barrelis placed in; S5, the drilling barrel is vertically screwed out of the ground, and meanwhile a locating cavity in the locating barrel is grouted; and S6, a pile rod is driven into the locating barrel.According to the pile driving equipment and the pile driving construction method, structure stability of a pile can be achieved without driving the pile into the sandy soil too deeply, construction steps are simple, controllability is high, and subsequent engineering construction is guaranteed.

Description

technical field [0001] The invention relates to the technical field of construction machinery equipment, in particular to a piling equipment and construction method suitable for desert geological conditions. Background technique [0002] Because if ground buildings are to be built on the ground, the ground must bear a lot of pressure, so it is necessary to ensure that the ground has sufficient strength to resist pressure, which is often difficult to do, so it is necessary to reinforce the ground that bears the building or To improve the bearing mode of the ground, it is thought of driving piles on the foundation, so that most of the weight of the building is transmitted to a deep position below the ground through piles, because the foundation at this position is much larger than the bearing capacity of the ground. [0003] With the development of domestic infrastructure, various roads, bridges, houses and other buildings have also become popular in some places with harsh geo...

AI Technical Summary

Problems solved by technology

Because these buildings need to be piled on the ground in many steps of construction, but due to the limitation of geological conditions, there is no good way to do it on this kind of sandy land except to drive the pile very deep. piling
