Sinorock produces a range of standard and high capacity self drilling bolt suited for various uses including: micropiles, tension rods, nailing, slope stabilization, etc.
Self drilling bolt micro pile serves as an economical solution for challenging soil conditions where installing conventional micropiles may not be the best option, for example, those with collapsible soils (those not conducive to open-hole drilling), large boulders or other obstructions.
Sinorock self drilling bolt offers an excellent choice for micro piles in difficult ground conditions where open-hole drilling isn’t possible. The continuously threaded bar profile lends itself perfectly for restricted headroom applications because the bar can be cut and coupled at any length.
According to the principle of application, micro pile can be divided into tensile pile, compression pile or alternating load type pile, and can also be used as anti slide pile under lateral load. According to the action mechanism, micro pile can be divided into end bearing pile and friction pile. According to the operating requirement, micro pile can also be divided into temporary micro pile and permanent micro pile.
