Problems solved by technology

The main disadvantages are: when encountering hard soil layers, sand layers, differentiated layers, and some soil layers that are not easy to press piles, greater penetration cannot be achieved, and the existing static presses cannot further press piles down;
Its main disadvantages are: it produces large noise and vibration, which directly affects the surrounding buildings. It is generally not su...

Embodiment Construction

[0021] In order to make the above-mentioned purpose, features and advantages of the present invention more obvious and understandable, a detailed description will be given below in conjunction with the accompanying drawings of the present invention.

[0022] In the following description, a lot of specific details are set forth in order to fully understand the present invention, but the present invention can also be implemented in other ways different from those described here, and those skilled in the art can do it without departing from the meaning of the present invention. By analogy, the present invention is therefore not limited to the specific examples disclosed below.

[0023] like figure 1 Shown, in this one embodiment, a kind of static pile driver reaming pile driving method, comprises the following steps:

[0024] S1: the static pile driver presses piles to a predetermined depth;

[0025] S2: The drill bit of the static pile driver enters the drill hole from the pil...

Abstract

The invention discloses a hole reaming and pile sinking method for a static pile driver. The method comprises following steps that the static pile driver presses a pile to reach the preset depth; a drill of the static pile driver enters a drill hole from a pile inner hole so as to finish drilling; and the static pile driver presses the pile to the designed depth. By employing the method, a problem that piles are difficult to sink in sand layers, hard soil layers, differentiation layers and some soil layers in which piles cannot be easily pressed is solved. According to the method, the hole is reamed firstly, and then the pile is sunk. The method is characterized in that the noise is low, the counterweight is small, less soil is extruded, the operation is easy, and the structure is simple and reliable.

Description

technical field [0001] The invention belongs to the technical field of drilling machinery equipment, drilling power machinery and transmission machinery of mechanical engineering and civil engineering, and relates to a large-scale horizontal directional drilling machine, in particular to a static pile driver reaming pile sinking method. Background technique [0002] According to its working principle, pile machinery can be divided into four categories: impact type, vibration type, static pressure type and hole-forming pouring type. Pile machinery is used to complete the penetration of prefabricated piles into the soil layer, including the operation process of driving, sinking, pressing, pulling out or pouring piles into holes, etc. It has been widely used in bridges, buildings, docks and Prefabricated pile construction in foundation construction such as ports. With the development of piling machinery, the piling hammer has developed from the traditional drop hammer, steam h...
