Description
本发明涉及高桩码头建造技术领域。更具体地说,本发明涉及一种高桩码头新型上部结构及其施工装备和施工方法。The invention relates to the technical field of high pile wharf construction. More specifically, the present invention relates to a new superstructure of a high pile wharf and its construction equipment and construction methods.
“桩帽型式”的高桩码头主体结构包括桩基、桩芯、桩帽、预制梁、预制板等构件,因其结构易于装配化目前被广泛应用,而传统的上部结构及施工装备、施工工艺带来的问题日益突出,传统高桩码头结构型式、施工装备及施工工艺均极大地影响了高桩码头的施工进度、质量、成本和安全。The main structure of the "pile cap type" high pile wharf includes pile foundation, pile core, pile cap, prefabricated beams, prefabricated panels and other components. It is currently widely used because its structure is easy to assemble. However, the traditional superstructure and construction equipment, construction Problems caused by technology have become increasingly prominent. The structural type, construction equipment and construction technology of traditional high-pile wharfs have greatly affected the construction progress, quality, cost and safety of high-pile wharfs.
桩芯、桩帽通常位于潮位变动区,传统施工工艺均为水上现浇作业,桩芯施工包括钢管桩内抽水、钢筋笼下放、混凝土浇筑等,桩帽施工包括底部搭设复杂的底模支撑体系、钢筋现场绑扎、模板安装以及较大方量的混凝土浇筑。以上水上施工易受风浪、潮位影响,施工窗口受限,工效低;钢筋位于浪溅区易锈蚀,施工质量差;水上作业量大,安全风险高。Pile cores and pile caps are usually located in areas where tide levels change. Traditional construction techniques are cast-in-place operations on the water. Pile core construction includes water pumping in steel pipe piles, lowering steel cages, concrete pouring, etc. Pile cap construction includes the erection of complex bottom form supports at the bottom. system, on-site lashing of steel bars, installation of formwork and larger amounts of concrete pouring. The above water construction is easily affected by wind, waves and tide levels, and the construction window is limited and the work efficiency is low; the steel bars located in the splash zone are prone to rust and the construction quality is poor; the water work volume is large and the safety risks are high.
预制横、纵梁节点处,传统节点结构型式钢筋密布,纵横交错,碰撞问题突出,作业空间小,现场焊接复杂,施工质量控制难度大。At the joints of prefabricated transverse and longitudinal beams, traditional joint structural steel bars are densely covered and criss-crossed, causing prominent collision problems, small working space, complicated on-site welding, and difficult construction quality control.
此外,易于装配化的高桩码头上部结构的预制构件较多,需要频繁进行起重吊装作业,而传统吊装设备如浮吊、顶升平台+起重设备等易受波浪影响,恶劣环境下施工工效低且作业窗口少。少数项目中使用架桥机将水上作业转为陆上作业,但针对离岸式宽平台码头,架桥机尺寸较为庞大,如采用浮吊或顶升平台+起重设备则只能先施工完成码头平台半幅,然后转换到另一侧完成剩下半幅的施工,施工工期长,如果采用多台装备同时作业,施工成本较高,经济性差。In addition, the superstructure of the high pile wharf that is easy to assemble has many prefabricated components and requires frequent lifting operations. However, traditional lifting equipment such as floating cranes, jacking platforms + lifting equipment, etc. are easily affected by waves and are constructed in harsh environments. The work efficiency is low and the operation window is small. In a few projects, bridge erecting machines are used to convert water operations to land operations. However, for offshore wide platform terminals, the size of the bridge erecting machine is relatively large. If a floating crane or jacking platform + lifting equipment is used, the construction can only be completed first. The dock platform is half wide, and then switched to the other side to complete the construction of the remaining half. The construction period is long. If multiple pieces of equipment are used to operate at the same time, the construction cost is high and the economy is poor.
