Bottom plate dewatering well plugging method
The invention discloses a bottom plate dewatering well blocking method. The method comprises the following steps that S1, concrete chiseling is conducted on the periphery of a dewatering well with the dewatering well at the position of a floor as the center; s2, drainage is continuously conducted, after it is confirmed that the water level is lowered, the upper dewatering well is cut off to the position below the floor finished surface elevation through oxygen welding cutting, the prefabricated reinforcement cage is placed immediately after cutting is completed, and upper reinforcing steel bars of the reinforcement cage are welded to original structural reinforcing steel bars; s3, the seamless steel pipe is put into a self-suction water pump for well interior dewatering; s4, first concrete is poured to the lower portion of the cut wellhead, the water suction pump continuously drains water, and the strength of the first concrete is maintained to 100%; s5, after the first concrete is poured and maintained completely, the top of the seamless steel pipe is sealed through a hot galvanizing screw thread pipe cap; s6, after the underground water level rises, continuously observing, and pouring second concrete until no water stain exists; s7, pouring third concrete; the bottom plate dewatering well plugging method is reasonable in design and standard in construction.
本发明公开一种底板降水井封堵方法，包括以下步骤：S1、以地板处降水井为中心对其四周进行混凝土剔凿；S2、持续进行排水，待确认水位降低以后采用氧焊切割将上部降水井割除至地板完成面标高以下，切割完成后随即放入预制钢筋笼，钢筋笼上部钢筋焊接于原结构钢筋；S3、通过无缝钢管放入自吸式水泵进行井内降水；S4、浇筑第一道混凝土至切割井口下部，抽水泵持续排水，养护第一道混凝土强度至100％；S5、第一道混凝土浇筑养护完全后，采用热镀锌丝扣管帽封闭无缝钢管顶部；S6、待地下水位上升后，持续观察后，无水渍方可浇筑第二道混凝土；S7、浇筑第三道混凝土；本发明提供了一种设计合理，施工规范的底板降水井封堵方法。
