Abstract

The invention discloses a drilling underground water sampler for house and municipal road drilling, and relates to the field of underground water samplers. The drilling underground water sampler comprises a protective cover and a water containing barrel, and a lifting beam is fixed to the top of the protective cover. By arranging the protective cover, the water containing barrel, a water inlet hole, a water inlet, a water leakage opening and a water inlet and stop valve, after the sampler is inserted into a drill hole, underground water enters the protective cover through the water inlet in the surface of the protective cover and the water inlet hole in the surface of an upper directional transmission shaft plate, then when the sampler reaches a designated position, the water inlet and stop valve is opened, the underground water in the protective cover enters the water containing barrel through the water leakage opening to be stored, and then the water inlet and stop valve is closed to ensure that the water containing barrel is closed. When underground water in the water containing barrel needs to be taken out for detection, a user can open the valve on a water outlet pipe, the whole process is safer, and the situation that the sampler is not in a closed state before and after water sampling is avoided.

Description

technical field [0001] The invention relates to the field of groundwater samplers, in particular to a borehole groundwater sampler for drilling houses and municipal roads. Background technique [0002] After the drilling of houses and municipal roads, groundwater should be used for water corrosion (erosion) analysis in the areas where groundwater is exposed. According to relevant specifications, the total amount of groundwater samples collected from boreholes should not be less than 2L. . [0003] The existing sampling of borehole groundwater is taken with ordinary plastic bottles. Its disadvantages are: first, it is inconvenient to operate, especially when the borehole groundwater is buried deep, and the air and borehole groundwater are mixed and dissolved when the sampler is not in use. The effect will cause errors in the analysis; the second sampling is slightly less representative, and it is not in a closed state before and after water sampling. Contents of the invent...
