Abstract

An embodiment of the invention provides a root key pushing device suitable for root type tubular pile foundation, which can be adjusted through rotation and can achieve flexible centering simultaneously. The root key pushing device comprises a lifting platform, a rotating platform and an adjusting platform from the bottom up, wherein the lifting platform is a bearing structure of the whole pushing device, bears gravity and impact force brought by the rotation operation of an upper-part member after supported and stabilized with the inner wall of the tubular pile, and is connected with external force simultaneously to perform integral lifting of the whole root key pushing device; a rotating shaft is arranged in the center of the lifting platform and is connected with the rotating platform; the rotating platform is provided with a rotary drum matched with the rotating shaft of the lifting platform, and the rotary drum is arranged on the rotating shaft of the lifting platform in a sleeving manner; and lateral spacing baffles are arranged on the adjusting platform and used for vertical and horizontal position adjustment during centering of the root key.

Description

technical field [0001] The embodiment of the present invention relates to the field of bridge construction, in particular to a root key pushing device suitable for root pipe pile foundations. technical background [0002] Traditional pile foundations mainly include bored piles, dug piles, sunken piles, prefabricated piles and other foundation forms. As a commonly used foundation form, the pile foundation is characterized by being able to effectively reduce the settlement of buildings, and being able to adapt to various strata. Buildings, tall tower structures with special requirements for inclination, and foundations that are prone to liquefaction due to earthquakes, etc. [0003] The pile foundation mainly exerts the frictional resistance around the pile and the bearing capacity of the pile end. As a foundation form of the pile foundation, the root pipe pile foundation has a large buried depth, good integrity, good stability, and can withstand large vertical and horizonta...
