Common deformed steel bar tensioning device, prefabricated square pile and process for prefabricated square pile
The invention discloses a common deformed steel bar prefabricated square pile which comprises unit pile bodies and a pile head. The common deformed steel bar prefabricated square pile is characterized in that common deformed steel bars are arranged in each unit pile body, the common deformed steel bars have low prestressing force in transverse hoisting or transporting, and stress is gradually dissipated in vertical pile making; the initial stress is consistent when the common deformed steel bars exert the low prestressing force, and the parallel common deformed steel bars in each unit pile body are equal in tensioning prestressing force. The low prestressing force exerted by the common deformed steel bars is formed by tensioning of a common deformed steel bar tensioning device, so that cracks of the pile in hoisting or transporting are avoided. The square pile has the advantages of being convenient to process, low in production cost, high in corrosion resistance, long in service life and the like, and is especially suitable for being used in seawater environments such as oceans and saline-alkali soil.
