Construction method of shoal foundation and construction system of shoal foundation
A shoal foundation construction method and a shoal foundation construction system relate to the technical field of lower structure construction of bridge engineering, and the shoal foundation construction method comprises the following steps: inserting and driving support piles at a designed construction position to form a closed enclosure structure, and installing an opposite-pull system to reinforce the support piles; filling soil in the enclosure structure layer by layer to a designed elevation to form an island building platform, and constructing cast-in-situ bored piles on the island building platform; and after construction of the cast-in-situ bored piles is completed, underwater soil in the enclosure structure is taken out to the designed elevation of the bottom, an inner support and an inner ring beam are installed, bottom sealing concrete is poured, bearing platform construction is conducted through water pumping, and construction of the shoal foundation is completed. According to the embodiment of the invention, the support piles are inserted and driven in water to form the closed structure, and soil is filled in the closed structure, so that the earth volume can be greatly reduced, the construction cost is reduced, and the construction efficiency is improved. In addition, a large steel structure does not need to be additionally erected, the steel consumption is greatly saved, and the construction cost is saved.
一种浅滩基础的施工方法及浅滩基础的施工系统，涉及桥梁工程的下部结构施工技术领域，其包括：在设计施工位置插打支护桩，形成封闭的围合结构，安装对拉系统对支护桩进行加固；在围合结构内逐层填土至设计高程，形成筑岛平台，在筑岛平台上施工钻孔灌注桩；待钻孔灌注桩施工完成后，取出围合结构内部的水下土至底部的设计标高处，并安装内支撑和内圈梁，浇筑封底混凝土，抽水进行承台施工，完成浅滩基础的施工。本申请实施例是在水中插打支护桩形成闭合结构，在闭合结构内进行填土，可大大减少土方量，从而减少了施工成本，提高施工效率。此外，不需要额外搭设大型钢结构，大大节省了钢材用量，节省了施工成本。
