  1. Excavation of the topsoil layer shall comply with the following regulations
    1. Ladder is installed in the well, and simple lifting facilities should not be used to lift personnel;
    2. When constructing the water-bearing surface soil layer, it is necessary to erect and strengthen the well circle in time, reinforce the dense back slab, and take measures to reduce the water level to prevent the erosion of the sand and soil on the shaft wall from causing empty siding.
            3. When constructing in unstable aquifers such as quicksand and silt, there are special safety technical measures.
            2. During the construction of the shaft, measures should be taken to prevent the objects from falling sharply. The wellhead should be provided with a temporary main buckle and the structure of the well cover door should be firm and tight. The slag unloading facilities should be tight, and leakage of slag into the well is not allowed. The tools and materials carried by the operators in the well should be tied firmly or placed in a tool bag. No materials or tools should be thrown into (or in) the wellbore.
            3. DTH Drill Pipe construction should adopt double-layer hanging plate operation. Before lifting the hanging plate, strictly check the suspension wire rope and signal device of the winch, and at the same time evacuate all operators under the hanging plate. The moving suspension plate should be directed by a professional person, and it should be fixed after moving. Cover the gap between the hanging plate and the shaft wall, and check to ensure that it is reliable, and the operation is accurate. Before lifting the bucket, the operator must make sure that the rope is stretched straight, the suspension plate is free and stable, and the tank can be moved after contact. Before moving the bucket or hanging plate, you must communicate with the tanker and signaler on the phone before you can move the tank.
            4. In the following situations, the operator should wear a seat belt, and one end of the seat belt should be correctly checked on the firm member.
                1. Remove the protective rock pillar or the protective platform;
                2. Install, repair or dismantle equipment in the wellbore or on the derrick;
                3. Dispose of suspended equipment, pipes and cables in the wellbore, or perform operations on the suspension plate;
                4. Ride in a bucket;
                5. After blasting, clean the pumice on the well circle;
                6. Pump lifting operation during wellbore construction;
                7. Top Hammer Drilling Tools performs supporting and locking operations at the mid-section wellhead that has been temporarily completed.
