Construction method and device for tube well dewatering and open excavation deep groove dewatering and drainage of oversized foundation pit
The invention discloses a construction method and device for tube well dewatering and open-cut deep groove dewatering and drainage of an oversized foundation pit, and relates to the technical field of foundation pit dewatering construction. According to the technical scheme, the construction method is characterized by comprising the following steps that firstly, a dewatering well is arranged on the outer side of a dam body site for dewatering; 2, synchronously excavating a plurality of groups of drainage open ditches at equal intervals in the field range of the storage pond; 3, dewatering the excavated soil, and transporting the soil to a dam body site area for filling; fourthly, when the water level in the water collecting well does not descend any more, the open drainage ditches continue to be excavated, and meanwhile the part between the open drainage ditches is excavated; and 5, the step 4 is repeated until the drainage open trench is excavated to the base, and final precipitation work is carried out. According to the scheme, the drainage open trench and the dewatering well are used for synchronous construction dewatering, and the filled soil transportation device is arranged in a matched mode, so that excavated soil can be synchronously transported to a dam body filling area, the high-continuity construction operation effect of foundation pit dewatering, excavation and filling is achieved, and the construction efficiency is greatly improved.
本发明公开了一种超大基坑管井降水与明挖深槽降排水施工方法及装置，涉及基坑降水施工技术领域，其技术方案要点是包括以下步骤：一、坝体场地外侧设置降水井进行降水；二、调蓄池场地范围内等距同步开挖多组排水明沟；三、将开挖后的土进行脱水，并将其运输至坝体场地区域进行填筑；四、当集水井内水位不再下降时，继续对排水明沟进行开挖，同时对排水明沟之间部分进行开挖；五、重复步骤四，直至排水明沟开挖至基底并实施最后的降水工作。本方案使用排水明沟与降水井同步施工降水，再配合填土运输装置是设置，使得开挖后的土能够同步向坝体填筑区运输，达到基坑降水、开挖、填筑的高连贯性施工作业效果，大幅度提高了施工效率。
