    Reference No.1

    Project name:

    3DAS series, Intelligent 3D adjustment system applied in Hongkong-zhuhai-macao Bridge


    Location: Lingdingyang


    Project Profile:

    Hongkong-zhuhai-macao Bridge(HZMB) is part of G94 highway, being situated at the waters of Lingdingyang of Pearl River Estuary, is a mega-size sea crossing linking Hong Kong, Zhuhai City and Macao. The functions of the Bridge can meet the demand of passenger and freight land transport among Hong Kong, Mainland and Macao, to establish a new land transport link between the east and west banks of the Pearl River, and to enhance the economic and sustainable development of the three places. The project includes a 29.6 km dual 3-lane carriageway and 6.7 km tunnel, this is the longest bridge-cum-tunnel structure in the world. designed speed is 100~120km per hour.


    Challenge:

    Prefabricated pile caps 3D positioning in deep water. Underwater positioning device need to be pre-installed in the prefabricated Caps. The collision issue between prefabricated pile cap and pre-installed cylinders in the process. Equipment reliability issues for use in deep water.


    Solution:

    Kattor provided solution including: four points synchronous lifting of steel pile and bridge pier, used 1200 tons of double acting cylinders to synchronous lift large diameter steel pile and bridge pier.

    Reference No.2

    Project name:

    Intelligent Synchronous Lifting System and Intelligent 3D adjustment system applied in Mau Bin Bridge repair work


    Location: Myanmar


    Project Profile:

    Mau Bin Bridge linking Rangoon and MauBin, which built in April 1994 and completed in February 1998. total length is 721.8m, consists of 8 spans of simple- supported T girder and 4 spans of continuous steel trussed girder. Bridge span 4*30m + 4*120 + 4*30m.


    Challenge:

    End expansion bearing of Main Bridge on P8 was damaged, result in big gap between truss beam and pre-stressed concrete girders, bridge bearing need to be replaced. Movement of Pier and bearing from approach bridge to Yangon side, result in no gap between two girders, need to horizontally move the whole bridge toward to designated position.


    Solution:

    1. Set 3DAS cylinders.
    2. P11, lift 10mm, check if it has any abnormal.
    3. P11, lift 70mm, place cushion block.
    4. P11, lower the beam on cushion block.
    5. Replacement of old bearing by new one.
    6. A2, lift up to 50% of total load.
    7. P11, lift up 5 to 10mm, remove the cushion blocks.
    8. Move toward Maubin for 10mm, check if there is any problem.
    9. Move toward Maubin to designated position.
    10. Adjust the position of bridge bearings on P11.

    Reference No.3

    Project name:

    3DAS series, Intelligent 3D adjustment system applied in Jingyue Yangtze Bridge


    Location: Hubei


    Project Profile:
    Jing-Yue Yangtze River (Highway) bridge, the north shore of bridge site locates in Jianli Hubei, and South bank is Yueyang Hunan, it’s the first bridge connects Hubei and Hunan provinces in the Yangtze River. It designed to steel box girder and twin towers, total length of Bridge over 5400 meters, with a total investment of over 2.3 billion RMB, two-way six-lane, the main span of hole up to 816 meters, ranking sixth in the world in the same bridge.


    Challenge:
    Bridge site with complex geological structure, and have navigation, flood controlling important constraints. Main span is 816m pre-stressed concrete girder bridge, total weight 3,200 tons, how to push the beam in place? How to achieve synchronous lifting under so harsh environment? How to complete beam precision position in small space?


    Solution:
    Kattor used PLC controlling system to control 3D cylinders, make it under full load conditions while achieving 1,500 tons of pushing force and 120 tons of longitudinal force, to complete beam precise position. Set tilt saddle with maximum tilt angles up to 5°on each of cylinders, to ensure the safety of the construction process
