High Precision Jacking Tube Rock Wool Material DN600 - DN1200 ISO2531 EN545

Progress Control

Based on the construction plan, each jacking project needs to be completed for the deadline after checking work content and commencement time. Jacking is more likely to face uncertain incidents related to soil conditions and groundwater compared with ordinary civil engineering works. In order to minimize the uncertain incidents, a pre-installation survey needs to be done thoroughly.

Materials and Equipments Control

The materials and equipments used in jacking need to be tested to whether or not they conform to the specification on their dimensions, strengths and materials. Fragile material products need special care for their handling.
