Dewatering construction process for large-opening well
The invention relates to the field of building construction, in particular to a large-opening well dewatering construction technology which comprises the steps that S1, well positions are constructed according to a well position plane layout drawing and a building foundation drawing; s2, earth is excavated in the well position manually, and a positioning groove is formed; s3, the positioning groove is subjected to sloping treatment; s4, a pile casing is embedded in the center of the positioning groove; s5, drilling is conducted on the bottom of the positioning groove through a well machine; s6, when the positioning holes are formed, cement pipes are placed in the positioning holes immediately; s7, a submersible pump used for pumping out slurry in the cement pipe is installed in the cement pipe; s8, the initial water depth in the cement pipe is measured, and related data are recorded until the water level drops to meet the excavation condition; s9, extension protection is conducted on the large-opening well; and S10, after pouring of the post-pouring belt is completed, the large-opening well is blocked. The method has the effects that the stability in the soil is guaranteed, and the risk of soil collapse is reduced.
本申请涉及建筑施工领域,尤其涉及大口井降水施工工艺，其包括S1、根据井位平面布置图并结合建筑基础图施测井位；S2、人工对井位处挖土开设定位槽；S3、对定位槽进行放坡处理；S4、向定位槽中心埋设有护筒；S5、通过井机向定位槽底部进行钻孔；S6、当定位孔成型时，立刻向定位孔内置放水泥管；S7、向水泥管内安装置放有用于将水泥管内的泥浆抽出的潜水泵；S8、对水泥管内的起始水深进行测量并记录相关数据，直至水位下降至满足开挖条件；S9、对大口井进行接长防护；S10、待后浇带浇筑完成后对大口井进行封堵。本申请具有保证土质内的稳定性，降低土质坍塌的风险的效果。
