Using Self-drilling Anchor Bolt System As A Mircopile
by Anchor S. Web DesignerThe 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.
