9. A rapid sampling method for soil detection for hydraulic engineering pipeline laying is realized based on the rapid sampling equipment for soil detection for hydraulic engineering pipeline laying according to any one of claims 1~8, and is characterized by comprising the following steps:
1) After the sampling rod assembly is assembled, the sampling rod assembly is righted by using a righting assembly;
2) The annular electromagnet in the punching assembly is powered off, so that the adsorbed movable core block moves downwards, and the sampling rod assembly is hammered and enters the soil; when the impact is finished once, the overturning motor drives the sleeve to overturn for 92 to 95 degrees, so that the movable core block is slowly reset, the annular electromagnet is electrified and adsorbs and fixes the movable core block, and the overturning motor resets;
3) The lifting component drives the stamping component to descend by a certain height;
4) Repeating the step 2) and the step 3) until the soil sampling is completed;
5) After sampling, the sampling rod assembly is pulled out and disassembled, and soil samples in the sampling rod assembly are stored in a layered mode.
