Pile hole capping mass hole cleaning equipment and pile hole capping mass treatment method by adopting equipment

Abstract

The invention discloses pile hole capping mass hole cleaning equipment and a pile hole capping mass treatment method by adopting the equipment. The hole cleaning equipment comprises a movable machinebody, a telescopic large arm, a vertical arm and a working pipe arm. A rotary hole cleaning disc is arranged on the working pipe arm, spiral transmission blades are arranged in the working pipe arm, arotary cutter blade is arranged on the rotary hole cleaning disc, and a feeding cavity is formed in the rotary hole cleaning disc. The capping mass treatment method comprises the steps that the rotary hole cleaning disc is rotated to amend the hole wall, and the rotary hole cleaning disc is placed down to the bottom end of a pile hole; the rotary hole cleaning disc is rotated to convey capping mass upwards, the rotary hole cleaning disc is placed down continuously, the contacted earthwork is conveyed upwards, till the position of the rotary hole cleaning disc is lower than a designed elevation of the pile hole; and after the capping mass at the bottom end of the pile hole is cleaned up, the rotary cutter blade is rotated to seal a soil inlet, the rotary hole cleaning disc is moved out toopen the soil inlet, and the spiral transmission blades are rotated reversely to make the earthwork fall down. By adopting the device, the capping mass at the bottom end of the pile hole can be effectively cleaned, the strength of the end of a pile foundation is improved, and the force bearing stability is improved.

Description

technical field [0001] The invention relates to the field of pile foundation construction, in particular to a pile hole floating soil cleaning device and a pile hole floating soil treatment method using the device. Background technique [0002] There are many kinds of pile foundation construction methods. At the present stage, due to the difficulty in guaranteeing the quality of prefabricated pipe piles and the limitations of the development and development of the industry, most of them still use the construction methods of hole-forming piles, including manual digging, auger drilling, and mud retaining walls. A variety of hole-forming methods corresponding to different geology, such as drilling method or rotary digging method. However, in the above method, when the hole is formed to the design hole depth elevation, on the one hand, due to the residual floating soil at the bottom of the hole, on the other hand, the disturbed earthwork on the hole wall will often be shaken dow...

Problems solved by technology

At this stage, the requirements for environmental protection are becoming increasingly stringent. The large amount of mud produced during the construction of mud retaining walls and the mud pool are not recommended for construction companies. Therefore, there are several other construction methods that urgently need to propose a method to deal with floating soil at the bottom of the hole to meet the needs.
