| description | The invention provides a ground direction adjusting device. The ground direction adjusting device comprises an outer casing, an inner casing and a weight reduction assembly, wherein the outer casing movably sleeves the inner casing, and the outer casing and the inner casing can relatively slide but cannot relatively rotate; the weight reduction assembly is installed in an inner hole of the inner casing. A method for laying a horizontal pipeline on a soft ground by using the ground direction adjusting device comprises the following steps of 1, digging a well; 2, placing a wellhead casing into the well; 3, placing the outer casing into the wellhead casing; 4, placing the inner casing into the outer casing and completing power connection of a drilling machine; 5, locking a drilling directionangle; 6, conducting drilling to a target layer; 7, laying the pipeline. By means of the device and the method, the pipeline can be horizontally laid in the soft and broken ground, so that it is possible to effectively extrac |
