Construction method for equipment foundation under sludge geological conditions in mudflat backfill area
The invention provides a construction method for an equipment foundation under a sludge geological condition in a mudflat backfill area. The construction method comprises the following steps that a sludge isolation piece sinks to a preset height of an outer ring at a pre-construction position of the equipment foundation, and sludge around the pre-construction position of the equipment foundation is extruded and isolated through the sludge isolation piece; earth in the sludge isolation piece is removed, and concrete pouring is carried out at the bottom of the sludge isolation piece to form a concrete cushion layer so as to seal the bottom of the sludge isolation piece; pouring of the equipment foundation is carried out on the concrete cushion layer in the sludge isolation piece; and after the strength of the equipment foundation is larger than a threshold value, the sludge isolation piece is hoisted out. According to the construction method, the sludge is extruded and isolated through the sludge isolation piece, the situation that the surrounding sludge extrudes the equipment foundation or falls off to extrude a pile core in the pouring process is avoided, the sludge isolation pieceis hoisted and placed in time, and the construction method is simple, convenient, fast, good in safety effect, capable of saving cost, high in applicability and capable of being repeatedly used.
本发明提供了一种滩涂回填区域淤泥地质条件下设备基础的施工方法，该施工方法包括如下步骤：将淤泥隔离件下沉至设备基础预施工位置处的外圈的预设高度处，以通过淤泥隔离件对设备基础预施工位置四周的淤泥进行挤压隔离；将淤泥隔离件内的土方进行清除，并对淤泥隔离件的底部进行混凝土的浇筑形成混凝土垫层以对淤泥隔离件进行封底；在淤泥隔离件内于混凝土垫层上进行设备基础的浇筑；在设备基础的强度大于阈值后，将淤泥隔离件吊出。本发明通过淤泥隔离件对淤泥进行挤压隔离，避免四周的淤泥在浇筑过程中挤压设备基础或掉落对桩芯进行挤压，淤泥隔离件吊运安放后及时，简单、方便、快捷、安全效果好、节约成本、适用性强、可重复利用。
