High-water-seepage type deep foundation pit dewatering-free drainage excavation construction method
The invention provides a dewatering-free and drainage-free excavation construction method for a high-water-seepage type deep foundation pit. The dewatering-free and drainage-free excavation construction method comprises the following steps that construction preparation is conducted; excavating the dry land of the foundation pit; sand suction pump rows are arranged in place; excavating under drainage of a sand suction pump; a pipe head of the sand suction pump is provided with a high-pressure water gun used for dispersing mud and sand at the bottom of the deep foundation pit to form a mud and sand mixture, and the sand suction pump is used for sucking out the mud and sand mixture and blowing and filling the mud and sand mixture to a designated mud containing area through the mud discharging pipeline. According to the method, foundation pit dewatering and drainage and foundation pit supporting are not needed, the construction efficiency is effectively improved, the construction period is shortened, the dewatering cost and the foundation pit supporting cost are saved, the sand suction pump is adopted for drainage operation, the conditions of dust, dust raising and the like are effectively avoided, and good environmental protection significance is achieved; the underwater excavation of the sand suction pump is combined with the bagged sand surface protection filling process, the construction period and cost of bagged sand construction are effectively saved, and good economic benefits and social benefits are achieved.
本发明所提出的一种高渗水型深基坑免降排水开挖施工方法，包括以下步骤：施工准备；基坑干地开挖；吸砂泵排就位布置；吸砂泵排水下开挖；所述的吸砂泵管头带有高压水枪，用于将深基坑底部泥砂冲散形成泥砂混合物，吸砂泵用于将泥砂混合物吸出，由排泥管线吹填至指定的纳泥区域。该方法无需进行基坑降排水及基坑支护，有效提高了施工效率，减少了施工工期，节省了降水成本、基坑支护成本，采用吸砂泵排水下作业有效避免了粉尘、扬尘等情况的发生，具有良好的环保意义，采吸砂泵水下开挖与袋装砂护面充填工艺相结合，有效节省了袋装砂施工的工期及成本，具有良好的经济效益和社会效益。
