Description
Technical Field
The invention relates to the technical field of civil engineering construction, in particular to large-scale tubular pile hoisting equipment.
Background
At the end of the last 60 th century, the hogftai bridge factory of the Ministry of railways began to produce pretensioned prestressed concrete pipe piles (abbreviated as PC pipe piles), which were mainly used for the foundation construction of railway bridge engineering; the post-tensioning prestressed concrete pipe pile was developed and produced in the 70 s. Since the 70 s, especially in the construction of Baoshan steel works in Shanghai, a large number of steel pipe piles introduced in Japan were used, which not only had high cost but also had poor durability. In order to meet the requirements of port construction development, a prestressed high-strength concrete tubular pile (PHC tubular pile for short) production line is introduced from Japan in the three navigation departments of Ministry of communications in 1987, the main specification of the PHC tubular pile is from 600mm to 1000mm of vertebra, in the later 80 years, Ningbo Zhedong cement products Limited company cooperates with related scientific research institutions, and a pretensioning method prestressed concrete thin-wall tubular pile (PTC tubular pile for short) is developed by reforming the PC tubular pile according to the characteristics of soft and weak silt geology in coastal areas of China, and the main specification of the PTC tubular pile is from 300mm to 600mm of vertebra. In 1989 to 1992, the original national building materials institute of Suzhou concrete cement products and Panyu yuyu City Qiaofeng cement products Limited company independently develop a localization prestressed high-strength concrete pipe pile by digestion and absorption of an introduced pipe pile production line according to the actual conditions of China, and the achievement is listed as a national key popularization project by the original construction department in 1993.
In the transportation lift by crane in-process tubular pile generally need design two fulcrums, its hoisting point need accord with the mechanics requirement, and the tubular pile piles up to be stocked and need use the cushion, and the tubular pile should be avoided vibrating, offend in lifting by crane the transportation, and present traditional tubular pile lifts by crane generally accomplishes its shortcoming lie in through the crane:
