一般农村用于灌溉稻、麦田,井深在50米以上的井,通称为深井,井管价值在5000～8000元左右。由于农村缺少拔废深井管的设备,一旦深井报废,废井管只能埋在地下。最近几年,辽宁锦县一些乡镇试用液压千斤顶拔废深井管,方法简单,效果很好,现介绍如下: 1.所用工具、设备 10～20吨的液压千斤顶两个,电焊机一台,专用工具一个(可用废料焊合),以及碎石、木料和钢筋等。 2.准备工作 (1)拆下井管之外的一切东西。 (2)在井管四周地面放一些碎
General rural irrigation rice, wheat fields, well depths of more than 50 meters in the well, commonly known as deep wells, well pipe worth about 5000 ~ 8000 yuan. Due to the lack of equipment for pulling deep-well pipes in rural areas, once the well is scrapped, the waste-well pipe can only be buried underground. In recent years, a number of townships in Jinxian Liaoning pilot hydraulic jack unplug the deep well pipe, the method is simple, the effect is very good, are as follows: 1. Used tools, equipment, 10 to 20 tons of hydraulic jack two, a welding machine, dedicated A tool (available waste welding), as well as gravel, wood and steel and so on. 2. Preparations (1) Remove everything except the well tube. (2) put some broken ground around the well tube
