Deep foundation pit excavation construction method
The invention relates to the technical field of building construction, and discloses a deep foundation pit excavation construction method. The method comprises the steps of step I, formulating a deepfoundation pit excavation scheme: formulating a slope excavation scheme, a steel sheet pile supporting excavation scheme and a ventilation channel deep foundation pit excavation scheme; step II, performing deep foundation pit excavation construction preparation: according to the slope excavation scheme, the steel sheet pile supporting excavation scheme and the ventilation channel deep foundation pit excavation scheme, performing deep foundation pit excavation construction preparation; step III, performing deep foundation pit excavation: performing deep foundation pit excavation according to the slope excavation scheme, the steel sheet pile supporting excavation scheme and the ventilation channel deep foundation pit excavation scheme; step IV, performing base dewatering and drainage protection treatment: enabling annular well points, dewatering wells, drainage ditches and water collecting pits to be arranged on excavated foundation pits; and step V, performing foundation pit cleaning and foundation pit inspection: performing leveling, gravel cleaning and inspection and acceptance on the base. The problems that an existing deep foundation pit excavation construction method is low inconstruction efficiency and high in construction cost are solved.
本发明涉及建筑施工技术领域，公开了一种深基坑开挖施工方法。该方法包括：步骤一、深基坑开挖方案制定：制定放坡开挖方案、钢板桩支护开挖方案和通风通道深基坑开挖方案；步骤二、深基坑开挖施工准备：根据放坡开挖方案、钢板桩支护开挖方案和通风通道深基坑开挖方案，对深基坑开挖的施工进行准备；步骤三、深基坑开挖：根据放坡开挖方案、钢板桩支护开挖方案和通风通道深基坑开挖方案，进行深基坑开挖；步骤四、基底降、排水防护处理：对开挖基坑进行环状井点、降水井、排水沟和集水坑的设置；步骤五、基坑清理和基坑检验：对基底进行整平、碎石清理和检查验收。本发明解决了现有的深基坑开挖施工方法存在施工效率低和施工成本高的问题。
