Super-long bridge core 토토 메이저 사이트
Cable bridge form retaining 토토 메이저 사이트
This high-efficiency long-span cable bridge 토토 메이저 사이트 is being used by us in the Dongi No. 1 Bridge (400-meter section of the Jeoksung-Jeongok road; Korea’s first earth-anchored cable-stayed bridge).
Structure materials
To develop the core materials 토토 메이저 사이트 required in long-span cable bridges, we are currently developing high-pressure concrete lifting 토토 메이저 사이트 (vertical height of 400 meters), low-temperature concrete pouring, and the anti-washout underwater concrete for offshore foundations.
- Items to develop
- High tower building purpose
- Towers exceeding 400 meters
- Anchorage building purpose
- Reduced anchorage cracks due to temperature change by more than 50%
- Offshore foundation building purpose
- Offshore slump flow 600 meters composite performance
- R&D
- Core 토토 메이저 사이트
- Materials development, pouring manual, pouring 토토 메이저 사이트
- Concrete that can be used for long- and wide bridges and that reduce construction time
- Test bed
- 토토 메이저 사이트 support for on-site concrete pouring
- Mock-up, construction process, pouring manual
- Final output
- High-altitude concrete lifting
- (High tower building purpose)
- Low-temperature concrete pouring
- (Anchorage building purpose)
- Multiple-performance concrete and on-site pouring manual
- Offshore foundation
< Goals to achieve
High-efficiency walled steel-pipe pile 토토 메이저 사이트
The walled steel-pipe piles linked by steel couplings can be used as a permanent foundation as well as a temporary dike as they support large loads.
In Korea, the walled steel-pipe piles have been used in port facilities, but lately have been suggested for use in offshore foundations for soft ground.
Large-section tunnel 토토 메이저 사이트
Practical TBM 토토 메이저 사이트
This 토토 메이저 사이트 uses a tunnel boring machine with minimal ground impact for use in crowded downtown areas, riverbeds, and seabed tunnels.
3D underground scanning 토토 메이저 사이트
This 토토 메이저 사이트 identifies changes in the degree of underground stability during excavation by means of 3D measuring 토토 메이저 사이트. Lotte E&C is using the 토토 메이저 사이트 in a number of construction sites.
Technologies to respond to large slope stability and long-depth weak ground
토토 메이저 사이트 for large slope stability
We employ the most reasonable, economical ways to build structures on large slope sections.
토토 메이저 사이트 for long-depth weak ground
We determine the best ways to cut construction time and respond to the settling possibilities of weak ground.
Special bridge building 토토 메이저 사이트
Ever wider and longer bridges are being built and builders are also working in difficult terrain such as high altitude and road crossings. Lotte E&C provides total solutions to these situations including pushing, heavy lifting, pulling, and rotation.
