Shield construction is the main method for constructing city tunnels, and segments are an essential lining material. Our company can provide a wide variety of segments to suit any construction or usage conditions.
Multiple arc-shaped precast concrete lining (PCL) segments are arranged around a tunnel cross section for decorating, finishing, repairing, or reinforcing a tunnel. These are mainly used for road tunnel repairs and reinforcement.
Depending on the height of the wall, these are divided into the self-standing panel wall and the anchored panel wall construction system. Both systems are supported by the soldier piles. These are used for widening roads and land, and for disaster restoration construction on sloping ground and roads.
Ground anchor construction is an effective measure for stabilizing sloping ground, and ground anchor plates are used as a reactive force system.
The power lines are progressively being placed underground to make efficient use of roads which are a public space. Our company provides high-quality prefab manholes and hand holes for underground tunnels.
These are used as soundproof walls for railway bridges. Our company can provide a wide range of concrete railing walls to suit any site.
Ultra-high-strength fiber-reinforced concrete is a material that has a compressive strength of over 150 N/㎟ and crack initiation strength of over 4 N/㎟. Compared to conventional concrete products, this allows for lighter weight and thinner parts, and streamlining of construction.
Pre-stressed concrete flooring manufactured by pre-tensioning using precast steel wire was developed for short-span bridges and water channel covers. We can design, manufacture, and construct to suit any site conditions.
Since precast construction materials are manufactured at a well-equipped factory, they deliver high accuracy, high strength, and high quality, and can also reduce construction schedules by eliminating site work. They have also been shown to have secondary effects such as safer working and reduced waste.
