Construction method and construction structure for preventing basement from integrally floating in construction and use stages
The invention discloses a construction method and a construction structure for preventing a basement from integrally floating in construction and use stages. The construction method comprises the following steps that a water collecting pit is arranged on one side of a basement outer wall on a basement bottom plate, and a water filtering layer is arranged on the outer wall of the water collecting pit; a water pressure drainage steel pipe is arranged in the water collecting pit; one end of an L-shaped water pressure releasing and draining steel pipe horizontally extends out and is embedded into the water filtering layer on the outer side of the water collecting pit, the other end of the L-shaped water pressure releasing and draining steel pipe vertically extends out of the basement bottom plate and is connected with one end of an elbow section of a U-shaped water pressure releasing and draining steel pipe, and the other end of the elbow section of the U-shaped water pressure drainage steel pipe is connected with a vertical water pressure drainage steel pipe and extends downwards to the position below a top plate of a sump; a submersible pump is arranged in the water collecting pit; the water can flow back into the water collecting pit from the water pressure release drainage steel pipe through the water filtering layer, so that the anti-floating water level acting force of the basement is not greater than the dead weight of the basement bottom plate and the top plate, and the basement floating accident is avoided in the basement construction and use stages; and the construction structure safety is ensured.
本发明公开了防止地下室在施工和使用阶段整体上浮的施工方法及施工结构，所述施工方法包括步骤：将地下室底板位于地下室外墙一侧设置集水坑，将集水坑外壁处设置滤水层；将集水坑内设置泄水压排水钢管；将L形泄水压排水钢管的一端水平伸出并埋设至集水坑外侧的滤水层内，另一端竖向伸出地下室底板、并与U形泄水压排水钢管的弯头段的一端连接，将U形泄水压排水钢管的弯头段的另一端连接竖向泄水压排水钢管、并向下延伸至集水坑顶板下面；将集水坑内设置潜水泵；其能透过滤水层从泄水压排水钢管流回集水坑内，确保地下室抗浮水位作用力不会大于地下室底板和顶板自重，保证地下室施工和使用阶段不会发生地下室上浮事故；保证施工结构安全性。
