Embodiment 1

[0031] See Figure 1-5 A secondary salted soil collapsed sampling device comprising a sampling tube 1, the sampling tube 1 is a circular drill rod shape, and the inner coaxial coaxial cohaxing is opened in the coated cavity 2, sampling The housing of the tube 1 is distributed axially, and the respective guiding holes 23 of the same loop are uniformly distributed in the circumferential direction.

[0032] The cavity 2 is fixed to the high pressure water pipe 4, and one end of the high pressure water pipe 4 projects the sampling tube 1, and is connected to the liquid pipe 6. Among them, the high pressure water pipe 4 passes through the liquid pipe 6 into the high pressure column, and the intubation 11 in the guide hole 23 is injected into the soil.

[0033] Each of the guiding holes 23 slides inserted with an in-tubing 11, and the high pressure water pipe 4 is connected by the telescoping tube 7, and the other end of the cannula 11 has a tapered structure, an insertion 11 inside. The...

Abstract

The invention relates to the technical field of soil remediation, and discloses a secondary salinization soil leacheate sampling device which comprises a sampling pipe, the sampling pipe is in a round drill rod shape, a cylindrical cavity is coaxially formed in the sampling pipe, a plurality of circles of guide holes are distributed in a shell of the sampling pipe in the axial direction, and the guide holes in the same circle are evenly distributed in the circumferential direction. A high-pressure water pipe is coaxially fixed in the cavity, and one end of the high-pressure water pipe extends out of the sampling pipe and is connected with a liquid inlet pipe. The tail end of the insertion pipe can be inserted into soil to inject leacheate, operation is easy and convenient, the sampling pipe can sample leached soil through the insertion pipe inserted into the soil, a soil sample and the leacheate in the soil can be conveniently taken back, meanwhile, a draining hole is formed in the sampling pipe shell, and the sampling pipe is convenient to use. More leacheate can conveniently enter the cavity, a sample obtained after soil leaching can be stably and effectively obtained, and detection and use are convenient.

Description

Technical field [0001] The present invention relates to the field of soil repair techniques, and more particularly to a secondary salinized soil colloration sampling device. Background technique [0002] Due to different planting habits, fertilization and mode, irrigation, etc., the main salt separation sub-content of the soil is also different, so the facility salt is repaired, and it should be appropriate. At present, domestic primary salinization of soil mainly controlled facilities such as engineering measures, biotects, agronomic measures. [0003] In situ soil eluting refers to applying a jetde to the soil by injection, it is permeated, and it is permeated to the contaminant and the contaminant, which ultimately makes it a mobilized compound, which needs to build a repair facility in place. Including cleaning liquid production system, soil underlayer collection system and tubing treatment system, the technology has high separation and removal efficiency in homogeneous, perm...
