Deep soil sampling device for base detection

Abstract

The invention discloses a deep soil sampling device for base detection, and belongs to the field of base detection. The deep soil sampling device for base detection is characterized in that a water supply pipe is fixed to the inner end wall of a drill rod, and a water spraying opening communicated with the water supply pipe is formed in the outer end wall of the drill rod; uniform irrigation operation can be performed on soil at a drilling position through a water supply pipe, elements contained in the soil flow along with water flow through soil infiltration, rapid sampling can be achieved by collecting soil leachate, and the rapidness and convenience of deep soil sampling during base detection are effectively improved; and the air bag is mounted in the drill rod, the soil at the drilling position can be pressurized by virtue of extrusion formed after the air bag is inflated and expanded so that components in the soil can be fully mixed in the water flow, and the comprehensiveness during sampling can be improved.

Description

technical field [0001] The invention relates to the field of base detection, and more specifically relates to a deep soil sampling device for base detection. Background technique [0002] Base testing usually refers to the operation of ground soil exploration and testing during construction. It usually requires sampling and analysis of the soil to detect the components contained in the soil and avoid harmful substances in the soil from affecting the construction. [0003] In the prior art, the deep soil sampling device based on base detection usually adopts the method of drilling to realize sample collection. In actual operation, the drill bit installed on the sampling device rotates into the soil to collect the soil for sample collection. Although this method can effectively collect soil samples, due to the wide soil stock, in order to ensure the comprehensiveness of soil sample collection, it is usually necessary to collect a large amount of soil at the same location, resu...

[0003] In the prior art, the deep soil sampling device based on base detection usually adopts the method of drilling to realize sample collection. In actual operation, the drill bit installed on the sampling device rotates into the soil to collect the soil for sample collection. Although this method can effectively collect soil samples, due to the wide soil stock, in order to ensure the comprehensiveness of soil sample collection, it is usually necessary to collect a large amount of soil at the same location, resulting in too many samples that are not easy to carry, and excessive collection Soil samples cause too much time lost in sampling, which affects the detection efficiency of the base
