Rotary piling equipment and piling method

Abstract

The invention provides rotary piling equipment, which comprises a mounting frame, a piling assembly, a rotating assembly and a pile embracing clamp. The piling assembly is slidably mounted on the mounting frame and comprises a pile hammer; the rotating assembly is arranged at the bottom of the mounting frame and comprises a first motor and a rotating cylinder, the rotating cylinder is rotatably connected with the mounting frame, the two ends of the rotating cylinder are open, the rotating center of the rotating cylinder and the pile hammer are coaxially arranged, and the first motor is in transmission connection with the rotating cylinder; the pile embracing clamp is fixedly connected with the rotating cylinder, and the embracing center of the pile embracing clamp and the rotating cylinderare coaxially arranged; and a spiral bulge is arranged on the peripheral face of a construction pile. Thus, the construction pile during rotating obtains impact force so as to achieve the effect of rotating impact for combined feed, through the spiral bulge arranged on the periphery of the construction pile, the construction pile is stably connected with surrounding soil during rotating feed, thus pulling resistance of the construction pile is enhanced, the construction process of pouring cement mortar is omitted, and the construction cycle is shortened.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a rotary piling device and a piling method. Background technique [0002] Existing piling equipment, such as "a vehicle-mounted guardrail drilling piling truck" developed by our company, the Chinese utility model patent with the publication number CN209261478U disclosed on August 16, 2019, during piling operations, due to the impact of the pile hammer , so that the outer peripheral soil wall of the pile vibrates and relaxes, and an irregular gap is formed between the pile and the pile, the construction pile is easy to loosen, and the pull-out effect is poor. In order to enhance the pull-out resistance, cement mortar needs to be poured downward along the outer circumference of the pile to firmly connect with the surrounding soil, resulting in increased procedures and long construction period.
