Full-thread pile pouring machine extruding soil body and pile-forming construction method thereof

Abstract

The invention provides a full-thread pile pouring machine extruding a soil body and a pile-forming construction method of the full-thread pile pouring machine extruding the soil body. A vertical frame and a winch are arranged on a base, a motor device is arranged on a guide rail of the vertical frame, pulleys are arranged at the top end and the bottom end of the vertical frame, one end of a hauling rope is fixedly connected with the winch, the middle section of the hauling rope is hung on the pulleys, and the other end of the hauling rope is fixedly connected with the top end of the motor device. A drill rod comprises a drill rod shaft and a drill bit, wherein the drill rod shaft is provided with a hollow concrete delivering cavity, and the drill bit is connected to the lower end of the drill rod shaft. A spiral drilling piece is arranged on the outer wall of the lower section of the drill rod shaft in a winding mode, multiple soil scraping pieces are arranged on the outer wall of the middle section in a winding mode and used for scraping, pressing and flatly extruding the inner wall of a pile hole, the motor device is provided with a motor frame and a machine core which is connected with the drill rod in a driving mode, the motor frame is connected with the guide rail of the vertical frame in a sliding mode, and a detachable conical head is connected to the position, adjacent to the drill bit, of the outer wall of the lower section of the drill rod shaft. Full-thread hole forming and pile forming can be achieved, the principle is simple and easy to understand, operation processes are convenient and rapid to perform, and the construction method has the obvious advantage of concrete spraying instantly in comparison with an existing thread pile.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a pile driver and a pile forming method thereof. Background technique [0002] The long auger drilling pile driver is a pile driver widely used in construction sites. Its main drill rod is driven to rotate by power. Exit the pile hole, and then pour concrete into the pile hole by the hollow main drill pipe and insert the steel cage to form a pile. Because the drill pipe structure and shape are different, the pile shapes are also different, but most of the pile bodies formed by the existing pile machine pile forming equipment and the pile forming method are small in bearing capacity, complicated in construction method operation, and poor in practicability. Contents of the invention [0003] In view of this, the technical problem to be solved by the present invention is to provide a pile machine with high pile-forming bearing capacity, strong pull-out resistance, simple oper...
