Problems solved by technology

Due to the complex technological process of pressure pouring superfluid concrete, there is no technology that mechanically drills into strong weathered and moderately weathered rock formations and simultaneously presses concrete into piles at one time
Generally, the hole is first introduced and then the drilling rig is used to form the pile, which has the disadvantages of complicated procedures, high construction cost, slow speed, and poor quality.

Abstract

The invention provides a drill grouting concrete pile forming drilling device with air and water supply and a drilling method of the drill grouting concrete pile forming drilling device, for filling the gap of mechanical technology of drilling to the intense-weathering and moderately-weathering rock stratum while realizing grouting concrete pile forming at one step at the preset due to the complicated process flow of grouting superfluid concrete pile in the drill grouting superfluid concrete pile forming method applied commonly in the current construction market. The drill grouting concrete pile forming drilling device with air and water supply comprises an air and water supply rotation device (1); the upper portion of the air and water supply rotation device is connected with a power head (2), one end of the power head (2) is connected with a main unit (3) of an auger driller through a power head output shaft, the lower end of the air and water supply rotation device is connected with an auger stem (4), the auger stem runs through an air and water feeding cavity (5), an upper flange (6) and a lower flange (7), and is sleeved with a stem core tube (8). The drill grouting concrete pile forming drilling device with air and water supply and the drilling method of the drill grouting concrete pile forming drilling device are applied to the building field.

Description

[0001] Technical field: [0002] The present invention relates to a drilling device and drilling method for air-supplying and water-supplying concrete piles. Aiming at the shortcomings of traditional construction methods, a method of drilling into strongly weathered and moderately weathered rock layers and forming piles with one-time pressure grouting is invented. device. [0003] Background technique: [0004] At present, a construction technology is commonly used in the construction market: the pile-forming method of superfluid concrete by drilling and pressing. The process of the method and the device is to drill to the design depth once, and lift the drill once to place the reinforcement cage to form a pile. Due to the complex technological process of pressure pouring superfluid concrete, there is no technology that mechanically drills into strong weathered and moderately weathered rock formations and simultaneously presses concrete into piles at one time. Generally, the ...
