Description of the invention: [Technical field to which the invention pertains] The present invention relates to a parallel method for sampling soil gas, in particular to a periodic monitoring of long-distance pipelines and large storage tanks or faults similar to the petrochemical industry, A parallel soil gas sampling method having an effect of increasing the effective monitoring distance by several times compared to the current conventional soil gas sampling method. [Prior Art] The conventional soil gas monitoring method (please refer to the fifth figure) is a vertical soil gas sampling pipe (6) along a long-distance pipeline, a fault or a device surrounding the large storage tank, and the soil gas sampling pipe (6) Connect a soil gas extraction device (7) with a soil gas analysis device (8). When conducting a soil gas survey, the «** gas sample in the soil gas sampling tube (6) is withdrawn by the soil gas extraction device (7) and analyzed in the extracted gas sample via the soil gas analysis device (8). Volatile organic compounds or other gaseous components. However, in the conventional soil gas monitoring method, the farther the soil gas sampling pipe (6) is from the gasoline source, the less the total volatile organic matter concentration of the soil gas is monitored. The soil gas sampling pipe (6) can be known from Table 1. The effective monitoring radius is only about 5 meters; therefore, the application of the conventional soil gas sampling method in the regular monitoring of underground long-distance pipelines, faults and large storage tanks, due to the long distance of pipelines, faults and the long circumference of large storage tanks, needs to be established. A large number of soil gas sampling points and the number of analyses.
