Scope

Main technical content: 1. This collection of drawings focuses on the pre-tensioned prestressed concrete mechanical-connected circular piles (abbreviated as "mechanical-connected circular piles"), which are divided into pre-tensioned high-strength concrete mechanical-connected pipe piles (abbreviated as "mechanical-connected pipe piles") and pre-tensioned high-strength concrete mechanical-connected bamboo-joint piles (abbreviated as "mechanical-connected bamboo-joint piles"). 2. Mechanical-connected circular piles are suitable for low-pad-footing pile foundations in industrial and civil construction projects and municipal engineering in areas with seismic fortification intensity of 7 or lower. They can be used as reference for low-pad-footing pile foundations in railway, highway, bridge, port, municipal, and water conservancy projects. When the pile foundation pad and the surrounding ground of the basement contain liquefied soil layers, measures such as eliminating liquefaction and reinforcing the pile body with dense reinforcement should be taken in accordance with the relevant provisions of the "Foundation Design Standard" DGJ08-11. After ensuring that the design requirements are met through calculations, the products in this collection of drawings can be used.
