Small radius can increase wear on a TBM tunnel drive by raising stress, friction, and cutter wear, leading to higher maintenance and alignment challenges.

Small radius can increase wear on a TBM tunnel drive due to higher friction and heat; extra lubrication helps reduce damage in tight micro tunneling curves.

A TBM tunnel curve can slow output more than expected due to increased friction, alignment issues, and operational challenges that impact tunneling speed.

Small radius lowers disruption for micro tunneling downtown by reducing noise, traffic interruptions, and surface repairs in busy urban areas.

Curves are where pipe jacking contractors lose time due to alignment, stress, and friction issues that slow progress and require extra checks and adjustments.

Small radius can cut shaft costs for micro tunneling by reducing the number and depth of shafts, minimizing surface disruption, and saving project expenses.
