Large-water-yield dewatering well steel cover plate secondary plugging dewatering construction method
The invention relates to a large-water-yield dewatering well steel cover plate secondary plugging dewatering construction method, and belongs to the technical field of building construction.The method comprises the following steps that S1, according to a construction drawing, the positions of all dewatering wells are determined, and all materials needed by construction are prepared; s2, a first steel cover plate is machined, and the first steel cover plate is preliminarily installed in the dewatering well; s3, a water pumping pipe connecting device is installed on the first steel cover plate, a water pumping pipe of a gasoline self-priming pump penetrates through the water pumping pipe connecting device, the gasoline self-priming pump is started, and dewatering is conducted on the dewatering well; s4, a first steel cover plate is welded immediately in the precipitation process, after precipitation is completed, the water pumping pipe is taken out, and micro-expansion concrete is poured on the first steel cover plate; and S5, after the concrete is condensed, a second steel cover plate is welded. The method has the effect of reducing the cost.
本申请涉及一种大出水量降水井钢盖板二次封堵降水施工方法，属于建筑施工的技术领域，其包括以下步骤：S1、根据施工图纸，确定全部降水井的位置，准备施工所需的全部材料；S2、加工第一道钢盖板，初步安装第一道钢盖板在降水井中；S3、将抽水管连接装置安装在第一道钢盖板上，再将汽油自吸泵的抽水管穿过抽水管连接装置，启动汽油自吸泵，开始对降水井进行降水；S4、降水的过程中随即将焊接第一道钢盖板，降水完成后，将抽水管取出，在第一道钢盖板上浇筑微膨胀混凝土；S5、待混凝土凝结后，焊接第二道钢盖板。本申请具有降低成本的效果。
