Soil sampling device for construction

Abstract

The invention provides a soil sampling device for construction, relates to the technical field of building construction equipment, and aims to solve the problem that volatile and semi-volatile organic compounds in soil can be volatilized after sampling of the soil by an existing soil sampling device, so that the accuracy of a soil detection result is influenced. The sampling bin is communicated with the trapping cylinder in the upper chamber through the electromagnetic three-way valve, so that the nitrogen drives the volatile organic compounds in the sampling bin to pass through the trapping cylinder, the adsorbent in the trapping cylinder adsorbs the volatile organic compounds so as to collect the volatile organic compounds in the soil, and when the volatile organic compounds are detected in a laboratory, the volatile organic compounds in the trapping cylinder can be desorbed; the sum of the volatile organic compounds desorbed from the trapping cylinder and the residual volatile organic compounds in the soil is the actual amount of the volatile organic compounds in the soil, so that the soil detection precision is improved.

Description

technical field [0001] The invention relates to the technical field of building construction equipment, in particular to a soil sampling device for construction. Background technique [0002] Building construction refers to the production activities in the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into real objects at designated locations. It includes basic engineering construction, main structure construction, roofing engineering construction, decoration engineering construction, etc. The place where the construction works is called "construction site" or "construction site", also called construction site. [0003] Building construction is a production activity that people use various building materials and mechanical equipment to build various building products in a certain space and time according to a specific design blueprin...

Problems solved by technology

[0007] In soil sampling testing, it is necessary to detect volatile and semi-volatile organic compounds in the soil. After the existing soil sampling device takes out the soil sample, it needs to be stored at low temperature, and the soil sample should be tested within a certain time limit. The detection increases the difficulty of the detection of volatile and semi-volatile organic compounds in the soil; after the soil samples are taken from the soil, they need to be transported to the laboratory for soil testing. During the transportation, the volatile organic compounds and semi-volatile organic compounds contained in the soil Sexual organic compounds will volatilize, resulting in certain errors in soil sampling detection. Therefore, a soil sampling device for construction is urgently needed to solve the above problems
