A guide device for a pile driver

Abstract

The invention relates to a guide device for a pile driver. The guide device is installed on the pile driver. The guide device is provided with a pile body press-in guide part and / or a pile body arrangement guide part. The pile body press-in guide part is used for During pile driving, the prefabricated pile body forms a sliding guide cooperation in the preset downward direction of the pile driver, so that the pile body of the prefabricated pile can be pressed into the ground along the preset downward direction of the pile driver, and the pile body is arranged and guided The part is used to form a limited fit with the previous precast pile along the preset arrangement track of each prefabricated pile, so that the precast pile body can be matched with each prefabricated pile according to the preset layout after being pressed into the ground. The arrangement trajectory of the present invention is arranged in a linear manner. The structure of the present invention is stable and the layout is reasonable. It realizes the function of guiding the prefabricated piles in the preset pressing direction, and can realize the linear arrangement of the prefabricated piles according to the preset arrangement trajectory. The function meets the requirements of use.

Description

technical field [0001] The invention relates to the field of pile foundation construction, in particular to a guide and guard device for a pile driver. Background technique [0002] In the field of pile foundation construction, it is often necessary to press prefabricated piles into the ground to form revetment embankments. Since some of the press-in piles are non-circular, such as prefabricated piles with an H-shaped cross section, and the arrangement of revetments and dams is often not in a straight line, the posture of each prefabricated pile pressed into the ground is not the same. Traditional piling The equipment is mainly adjusted by manual experience. The attitude of the pressed prefabricated piles is quite different from the preset attitude, which makes the appearance of the entire revetment embankment messy or partially missing. These problems need to be solved. Contents of the invention [0003] The purpose of the present invention is to provide a guide device f...

Problems solved by technology

Since some of the press-in piles are non-circular, such as prefabricated piles with an H-shaped cross section, and the arrangement of revetments and dams is often not in a straight line, the posture of each prefabricated pile pressed into the ground is not the same. Traditional piling The equipment is mainly adjusted by manual experience, so the posture of the pressed prefabricated piles is quite different from the preset posture, which makes the appearance of the entire revetment embankment messy or partially missing.
