Concrete pile construction equipment and construction method thereof

Abstract

The invention aims at providing construction equipment for a concrete pile. The construction equipment for the concrete pile comprises a protective cylinder, a heavy hammer, hoists, a chassis and a support and is characterized in that a large hoist and a small hoist are fixed on the chassis; the support is arranged at the front end of the chassis; a pulley is arranged at the upper end of the support; a steel wire rope in the large hoist penetrates pulleys at the tops ends of the support and the heavy hammer to drive the heavy hammer to rise and fall; a steel wire rope in the small-power hoist penetrates the support pulley and a reversing device to drive the protective cylinder to rise and fall; the upper end of the protective cylinder is provided with a perpendicularity control device, a padding opening and a vibration device. The invention also comprises a construction method adopting the concrete pile. The construction method adopting the concrete pile comprises the following steps of (1) enabling equipment to be in position; (2) promoting the heavy hammer to impact and squeeze soil bodies sink into the protective cylinder after the soil bodies form into a pile hole; (3) repeatedly hammering a punching hole and sinking the protective cylinder to the designed depth; (4) performing pile tip processing through one method of a plurality of methods according to the soil layer characteristics and the upper portion loading requirement; (5) constructing a pile body through one method of a plurality of methods.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to pile construction technology. Background technique [0002] In the foundation treatment of buildings, it is often encountered that there are dense sandy soil layers, gravel soil layers, loess layers, gravel and pebble layers, etc. at a certain depth below the surface, and the hardness of these soil layers is uneven. , Uneven thickness. This geological condition makes it very difficult to form holes in the pile body during pile foundation construction. At present, it is difficult to form pile holes to the design depth with the commonly used methods such as vibratory sinking, static pressure or rotary drilling, which makes construction difficult. Increase and extend the construction period. Although rotary drilling rigs and manual digging can form holes in relatively hard soil layers, they are both methods of taking out the original soil. Not only does it need to clear the soil a...

This geological condition makes it very difficult to form holes in the pile body during pile foundation construction. At present, it is difficult to form pile holes to the design depth with the commonly used methods such as vibratory sinking, static pressure or rotary drilling, which makes construction difficult. increase, the extension of the construction period

Although rotary drilling rigs and manual digging can form holes in relatively hard soil layers, they are both methods of taking out the original soil. Not only do they need to clear the soil and transport it outside, resulting in increased costs and environmental pollution, but also because the original soil and soil are not fully utilized. Without the retaining wall, it is very easy to cause the hole wall to collapse and shrink, especially when the groundwater content is high, the pile hole will be flooded with water quickly, and the next step of construction cannot be carried out
