2.1 Background

Traditional WF beam piles resist wind uplift, horizontal loads and overturning moments mainly by pile length and pilesoil friction, leading to high steel consumption and expensive ocean freight for long piles; softsoil sites demand excessive embedment depth.

2.2 Solution: Composite Foundation System

The composite foundation system replaces conventional single WF beam piles with distributed inclined screw piles + surfacebearing plate. Multiple piles work in spatial synergy instead of singlepile concentrated loading.

2.3 Applicable Scenarios

Longpile replacement: PV projects requiring deepembedment long piles

Special soil & operating condition: soft grassland, desert; restrictedspace & harddriving sites

Sites with frostheave and foundation tilting risks

2.4 Core Advantages

Cuts steel consumption as well as material & shipping costs.

Better geological adaptability: easier installation, shorter embedment; solves tilting & frostheaveinduced foundation failure.

Nearsurface restraint from surface plate; multidirection inclined piles enable reliable load transfer, excellent antioverturning and antiuplift performance.
