Installation of self drilling and Swellex soil anchor

The self drilling soil anchor is designed for optimized installation, tailored to the project's needs.  By drilling a hole in collapsing soil or loose rock, with a sacrifi cial drill bit and a hollow rod, and after the drilling operation injecting grout into the hollow rod and surrounding cavity, makes it a top productivity solution.

The Swellex soil anchor is a folded steel tube, which is inserted into a pre-drilled hole in the rock. Water is blasted into the tube at high pressure, blowing out the fold and expanding the tube into the exact shape of the hole, adapting to every irregularity. Bolt installation takes less than 30 seconds, and provides full and immediate support along the entire hole length, in ground conditions ranging from the hardest rock to clay even non-cohesive material.

Soil nail is basically a steel bar encapsulated in a cementitious grout to transfer tensile load from less stable active zone of retained soil mass to the more stable passive zone. Typically, soil nails are spaced at close spacing to achieve massive soil-nail interaction within the soil mass for its reinforcement effect. 

Soil nailing represents a highly efficient method of constructing near vertical slopes. The system allows Developers & Engineers to maximise the potential development footprint of a site. We have installed several different nail systems including Dwidag & Ischebeck Titan for both temporary and permanent works. We have installed anchor piles and ground slabs for the telecommunications industry.

Sinorock soil nail company has been involved in soil nailing and rock anchoring for a number of years. We offer all kinds of self drilling soil nailing system.

Soil Nail Process

Soil nail is a continuous thread rod can be cut and connect at any point to fit work in the narrow construction. When processing the thread soil nail, thread-rolling machine is the main equipment. The thread quality has improved largely than primary pipe threader, thread surface is smooth and tensile strength is improved.

During soil nail rolling process, soil nail is located between two rollers, there are supporting block and strut bar below. The height of supporting block and strut bar should be corrected and controlled frequently to maintain level of soil nail.

Rolling pressure can not only influence quality of thread, but also influence precision and lifetime of equipment. If rolling pressure is big, thread and thread-rolling machine will have defect and loss. If rolling pressure is small, the pitch diameter of thread will big and outer diameter is small, thread form is not full and tensile strength will decrease; Choosing appropriate rolling time should depend on several factors, such as rolling pressure, material’s physical property, size and shape, etc.
