Supporting construction method for high-water-level sandy soil geology first-level foundation pit and foundation pit structure
The invention discloses a supporting construction method for a high-water-level sandy soil geology first-level foundation pit and a foundation pit structure, and relates to the technical field of construction buildings. The supporting construction method for the high-water-level sandy soil geology first-level foundation pit comprises the following steps that a plurality of opening protection pipes are buried in an earthwork area, and dewatering holes are drilled in the opening protection pipes; the tube well is placed in the dewatering hole, and the submersible pump is installed in the tube well; a plurality of first pile casings are embedded in the earthwork area, and first pile holes are drilled in the first pile casings; slurry is poured into the first pile holes for construction to form cast-in-place piles, and construction is conducted between the tops of the cast-in-place piles to form crown beams; the earthwork area is excavated until the height of the surface of the soil body of the earthwork area is the elevation of the bottom of the inner supporting beam; mounting an inner support beam to connect a plurality of cast-in-place piles; and the earthwork area is excavated until the height of the surface of the soil body of the earthwork area is the elevation of the pit bottom of the foundation pit, so that the foundation pit is formed. The foundation pit constructed through the supporting construction method for the first-level foundation pit in the high-water-level sandy soil geology is good in water stopping and dewatering effect.
本发明公开了一种用于高水位砂土地质一级基坑的支护施工方法及基坑结构，涉及于施工建筑技术领域；用于高水位砂土地质一级基坑的支护施工方法包括由如下步骤：在土方区处埋入若干护口管，在护口管处钻降水孔；将管井放入降水孔内，将潜水泵安装至管井内；在土方区处埋入若干第一护筒，在第一护筒处钻第一桩孔；将泥浆灌入第一桩孔内施工形成灌注桩，在灌注桩顶部之间施工形成冠梁；开挖土方区，直至土方区的土体的表面所位于的高度为内支撑梁底的标高；安装内支撑梁连接若干灌注桩；开挖土方区，直至土方区的土体的表面所位于的高度为基坑坑底的标高，以形成基坑。使用用于高水位砂土地质一级基坑的支护施工方法建设的基坑止水降水效果较好。
