On June 12th, at Meeting Room 209 of Wentian Hall, Hohai University, China Water Transportation Construction Association hosted the evaluation meeting for the three scientific and technological achievements declared by CHEC, namely, "Research on Planning for Logistics Nodes and Main Channels in West Africa", "Research and Application of Key Technologies in Wharf Reconstruction at Former Site and Ultra-low Temperature Cold Storage Integration Construction" and "Research and Application of Key Technologies in High-pile Wharf Construction under the Condition of Long-period Surge and Bare Rock in the Arabian Sea". The evaluation committee is composed of eight experts with Xu Guang, the former chief engineer of the Ministry of Transport as the chairman of the evaluation committee. As appraised by the evaluation committee, the three scientific and technological achievements have reached the international advanced level.

With regard to the "Study on Planning for Logistics Nodes and Main Channels in West Africa", a study on planning methods and overall plans was carried out based on the planning demand for the future development of logistics systems in 16 west African countries. For the first time, CHEC established a set of large-scale logistics channel planning and analysis methods suitable for the lack of basic materials, put forward the planning scheme for logistics node and the "two horizontal and five vertical" channels, and constructed the quantitative method of timing sequence for the logistics channel construction in West Africa. 

The "Research and Application of Key Technologies in Wharf Reconstruction at Former Site and Ultra-low Temperature Cold Storage Integration Construction", is based on the Bella Fishing Pier in Mozambique. They integrated the automatic ice-making, ice-storage and ice-transporting systems of slice ice machine, automatic ice storage bin and wind-powered ice transporting for the first time and as well constructed a -60℃ ultra-low temperature cold storage on the surface of high-pile wharf. Thus, the wharf has the full set of aquatic product line and further processing functions, such as processing, quick-freezing, cold storage and transporting. CHEC has also developed reverse lifting shaft frame, reverse lifting device, rapid installation and removal devices, realizing high-quality, efficient and safe installation of bottom formwork for support panel, steel tube for hoisting construction and berthing members that reduces engineering cost.
The "Research and Application of Key Technologies in High-pile Wharf Construction under the Condition of Long-period Surge and Bare Rock in the Arabian Sea", is based in Hubu Coal Wharf Project in Pakistan has put forward the general plane layout scheme, such as off-shore island breakwater, bank-connecting dike, permeable bridge approach and high-pile wharf that uses the temporary steel trestle for construction of offshore wharf, turning "over-water construction" into "construction on land". CHEC developed the construction technology that integrates steel casing batting, drilling; rebar cage lowering, pile foundation pouring and other functions. This helped realizing the integrated and efficient construction of drilled pile under complex sea conditions as well as special geological conditions of bare rock, which has a broad popularization and application prospect.

In this evaluation meeting for scientific and technological achievements, CHEC demonstrated its technical strength in logistics, wharf reconstruction, automatic system, offshore wharf construction, and other aspects, providing a strong technical support for CHEC overall layout in overseas market under the "Belt and Road" Initiative.
