Embodiment

[0029] Embodiment: This embodiment specifically relates to a static penetrating groundwater sampling method, which includes the following steps:

[0030] (1) if Figure 4 As shown, a set of groundwater sampling system is set on the ground to be sampled, and this groundwater sampling system has a movable platform 16, which can be freely moved on the ground by two crawler belts 6 at the bottom of the movable platform 16; The mobile platform 16 is vertically provided with two hydraulic cylinder devices 7 at a certain distance, and the two groups of hydraulic cylinder devices 7 are connected by a horizontal beam 11, that is to say, the horizontal beam 11 can be lifted and lowered synchronously with the hydraulic cylinder device 7 ;

[0031] In addition, a rotary power device 12 is fixedly installed on the horizontal beam 11, and the rotary power device 12 can be directly pressed or rotated for drilling; the rotary power device 12 has different installation positions, and the oute...

Abstract

The invention discloses a static cone penetration test type underground water sampling method. The method is characterized in that the sampling method comprises the following steps: an outer sleeve is pressed into a position above a sampling depth of the soil, and soil in the outer sleeve is emptied; in the outer sleeve, a static cone penetration test type underground water sampler is pressed into the sampling depth, and the sampler is permitted to stand for collecting underground water. The method is advantageous in that the underground water sampling method is convenient and rapid to operate, pollution can be isolated, underground water sampling can be carried out at any designated sampling depth in maximum injection depth range, and direct contact to human is avoided.

Description

technical field [0001] The invention belongs to the technical field of environmental geotechnical engineering, and in particular relates to a hydro-soil integrated sampling method of static penetrating sounding collection. Background technique [0002] With the rapid development of society and economy, the level of urbanization has been continuously improved, but the environmental pollution has become increasingly serious, seriously destroying the ecosystem and affecting the quality of life and health of human beings. In the process of redevelopment of contaminated sites, comprehensive and accurate site surveys are very important to prevent and control ecological accidents at construction sites and construction safety accidents caused by soil and groundwater pollution. [0003] The static penetrating technology (CPT) in geotechnical engineering refers to the in-situ test method that uses the static pressing device to press the penetrating rod connected to the probe into the ...
