我省在南昌港和樟树港的直立式浆砌石码头工程中,前趾下面采用预制无底盖钢筋混凝土小宝箱,从而解决了水下施工的困难,取得了码头岸壁前的要求水深。码头的基本结构为:将预制无底盖钢筋混凝土小空箱搁置在整平的抛石基床上,箱内和箱后抛填碎石和块石,其上为浆砌块石墙体,从而构成重力式码头。 In the vertical masonry wharf project of Nanchang Port and Zhangshu Port in our province, the prefabricated bottomless reinforced concrete mini-box was used under the front toe to solve the difficulties of underwater construction and obtain the required water depth in front of the quay wall. The basic structure of the wharf is that the prefabricated capless reinforced concrete small empty box is placed on the level of rubble base bed, the inside of the box and the box are thrown with gravel and rock, and the above is a masonry stone wall so as to Constitute a gravity wharf.
