Construction method of underwater bearing platform
The invention relates to a construction method of an underwater bearing platform, which is suitable for an underwater environment with a flow plasticity sludge layer and comprises the following steps that a back-silting prevention protection groove is formed in the periphery of a preset bearing platform foundation pit position, and the groove bottom of the back-silting prevention protection groove is higher than the elevation of the bottom of the bearing platform; a bearing platform foundation pit is excavated, and sludge in the back-silting-preventing protection groove is cleaned at regular time; a steel casing and a steel hanging box are sequentially arranged in the bearing platform foundation pit, and the steel hanging box is provided with a reinforced concrete bottom sealing bottom plate; and concrete is poured into the steel hanging box, and the bearing platform is obtained. The anti-back-silting protection groove is formed in the periphery of the foundation pit, back silting of a riverbed can be prevented after the bearing platform foundation pit is excavated in place, and the depth of the foundation pit can meet the construction space of the steel hanging box by regularly cleaning sludge in the anti-back-silting protection groove.
本发明涉及水下承台的施工方法，适用于具有流塑性淤泥层的水下环境，包括以下步骤：在预设的承台基坑位置的外围设置防回淤护槽，所述防回淤护槽的槽底高于承台底的标高；开挖承台基坑，定时清理所述防回淤护槽的淤泥；在所述承台基坑内依次设置钢护筒和钢吊箱，所述钢吊箱具有钢筋混凝土封底底板；在所述钢吊箱内浇筑混凝土，得到承台。通过在基坑的外围设置防回淤护槽，能够防止承台基坑开挖到位后，河床出现回淤，通过定时清理防回淤护槽内的淤泥，使得基坑深度能够满足钢吊箱施工空间。
