Using Self-drilling Anchor Bolt System As A Mircopile

by Anchor S. Web Designer

The structure of self-drilling hollow bolts used as micro piles includes hollow bolts with continuous threads, and OPC cement slurry with a minimum strength of 25N/mm2, which can also transmit tensile and compressive forces to the ground. Self-drilling hollow bolts are used as micro piles to transfer tensile and compressive loads to deeper bearing soil layers.

Compared with traditional piles, the advantages of self-drilling micro piles are:

l  Withstand compressive and tensile forces

l  No need for temporary casing

l  Improve the internal mechanical action of the floor/grout

l  Easy installation, greatly improve production efficiency

l  Small rotary impact equipment can be used

l  Can be installed in confined spaces

Self-drilling hollow bolts used as micro piles have a working bearing capacity ranging from 110kN to 3660kN

Vibration-free drilling can be used, low vibration, low noise, minimal damage, and no damage to adjacent buildings.

Self-drilling hollow bolts used as micro piles offer great benefits for excavation and concrete base schemes, as well as great convenience for safety concerns. The practical applications of self-drilling micro piles in building foundation engineering include:


Application 1:

Adjacent to the street of private residences, the construction of basements makes full use of self-drilling hollow bolt micropiles, which form an integral part of the substructure with the foundation and ground level.


Application 2: Foundation Restoration of Buildings

Since the foundation of the ancient building has no reinforced concrete supporting structure, the settlement occurred in the years. In order to restrain the deformation, self-drilling micro piles are used to control and restrain the development of the deformation.


Application 3: New construction micropiles

When self-drilling hollow bolts are used as micropiles in construction foundation projects, they have become increasingly popular because of their simplicity, reliability, practicality and high efficiency.
