Description

Technical Field

[0001] This utility model relates to the field of precast support pile technology, specifically a prestressed hollow rhomboid support pile. Background Technology

[0002] Support piles are generally used for foundation pit support, slope support and landslide control. They bear horizontal earth pressure or landslide thrust. Currently, precast support piles are widely used in the support of various foundation pits, protective dikes and riverbanks. They are mainly used for foundation pit support, slope support and landslide control, bearing horizontal earth pressure or landslide thrust. The strength requirements for vertical bearing capacity are not so high.

[0003] However, most precast support piles currently used are simply large-diameter pipe piles or hollow square piles. Hollow square piles are prone to tilting during installation and have shortcomings in support performance. When large-diameter pipe piles are used as support piles, the prestressed steel bars are uniformly arranged around the circumference, which does not match the stress characteristics of the pile body, resulting in material waste. In view of this, a prestressed hollow rhomboid support pile is proposed. Utility Model Content
