Guide device for pile driver

Abstract

The invention relates to a guide device for a pile driver. The guide device is arranged on the pile driver and provided with a pile body press-in guide part and / or a pile body distribution guide part,wherein the pile body press-in guide part is used for forming sliding guide fit with a pile body of a prefabricated pile in the preset press-down direction of the pile driver during piling so that the pile body of the prefabricated pile can be pressed underground in the preset press-down direction of the pile driver, and the pile body distribution guide part is used for forming limiting fit withthe previously driven prefabricated pile along the preset distribution track of the prefabricated piles so that after the pile body of the prefabricated pile is pressed underground, the pile body of the prefabricated pile and the driven prefabricated piles can be distributed sequentially along the preset distribution track. The guide device is stable in structure and reasonable in layout, can guide the prefabricated piles in the preset press-down direction, and can be used for sequentially distributing the prefabricated piles according to the preset distribution track, so that the use requirements are met.

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. These problems need to be solved
