According to the method for preventing ponding of the quay crane girder, ponding of the girder is prevented, the girder comprises a bottom plate, a pair of webs located on the two sides of the bottom plate and a cover plate located on the tops of the webs, a plurality of partition plates are further arranged in the space defined by the webs and the bottom plate, node plates are further arranged on the webs, and the node plates and the cover plate are welded. According to the method, the height of at least part of the cover plates located in the range where the gusset plates are located is larger than the height of the cover plates not located in the range where the gusset plates are located, so that the cover plates form gradients. The method can effectively prevent water from being accumulated on the cover plate. The invention further provides a quay crane girder water accumulation prevention structure and a girder preparation method.

    提供一种岸桥大梁防积水的方法,防止大梁积水,大梁包括底板、位于底板两侧的一对腹板以及位于腹板顶部的盖板,腹板和底板围成的空间内还设有多个隔板,腹板上还设有节点板,节点板与盖板焊接,该方法使位于节点板所在的范围内的至少部分盖板的高度大于不位于节点板所在的范围内的盖板高度,以使盖板形成坡度。该方法能够有效防止盖板上产生积水。还提供一种岸桥大梁防积水结构和大梁制备方法。
