tunnel structure and construction method using multiple self-balanced lining segments, and lining segment with self balanced plate

摘要

The invention of the Tunnel bokgong ( ) or tunnel portal ( ) ( : lining) by way of Civil Process ( ) in order to take advantage of ready-made concrete Costume Ball (Precasted Concrete lining) of the division ( ) The arc hieroglyphic plate ( : segment) relates to the arc hieroglyphs on board Using attached to the reaction for ( ) projecting dawn plate hameuroseo a structure that generates the required resistance moment to offset the overturning moment acting in the tunnel, while the unit arc hieroglyphic version (Segment) a step-by-step construction ( ) fill the earth and sand or rubble and cement milk, etc. in an external hameuroseo in parallel to a kind of permanent anchorage plate (Anchor) role dawn reduce the earth pressure acting on the tunnel and compression for bokgongpan ( : compressive zone) at the same time bokgongpan outer portion forming the backfilling Orthopedic bokgongpan ( : self balanced lining segment) increase the stability and permanence of the tunnel sikimyeo Article clothing tool can be self-reliant and good workability parties in the construction and production technology to complete the construction of the tunnel and take advantage of the bokgong intended to provide.
