Soil sampling device for construction engineering

Abstract

The invention discloses a soil sampling device for construction engineering. The device includes a fixing base. Multiple supporting feet are uniformly arranged on the bottom of the fixing base. A vertical sampling cylinder is sleeved in the middle of the fixing base. The upper and lower ends of the vertical sampling cylinder are open. A cabin is arranged above the fixing base. A vertical slide rodis arranged on the left side of the bottom of the cabin. The vertical slide rod is sleeved in a vertical sleeve arranged at the corresponding position of the fixing base and passes through the fixingbase. The invention provides the soil sampling device for construction engineering, which is ingenious in structure and reasonable in arrangement. The soil sampling device realizes efficient manual soil sampling and is convenient in operation. The soil sampling device is ingeniously provided with telescopic supporting frames wo facilitate the supporting and the adjustment of the height. The soilsampling device is ingeniously provided with a manual lifting mechanism so as to improve the soil sampling efficiency and help to collect the sampling mechanism in the soil. The soil sampling device is ingeniously provided with a manual driving mechanism to realize the convenience and labor saving of the sampling.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a soil sampling device for construction engineering. Background technique [0002] Soil refers to a layer of loose material on the surface of the earth, which is composed of various granular minerals, organic matter, water, air, microorganisms, etc., and can grow plants. Soil is composed of minerals, animals and plants from weathering of rocks, organic matter produced by the decomposition of microbial residues, soil organisms (solid phase substances), water (liquid phase substances), air (gas phase substances), oxidized humus, etc. [0003] Solid matter includes soil minerals, organic matter, and nutrients obtained by microorganisms through photoinhibition and sterilization. Liquid matter mainly refers to soil moisture. Gas is the air that exists in the pores of the soil. These three types of substances in the soil constitute a contradictory unity. They are int...

Problems solved by technology

Backfill refers to the construction process of taking soil backfill within 5m after the foundation, cushion and other concealed works are completed, and the backfill needs soil testing before and after construction, and soil testing involves soil sampling. Existing soil sampling Although the device is simple in structure and low in cost, it is time-consuming and laborious, and it is prone to clogging when taking soil. Soil sampling is difficult and cannot meet the needs of soil sampling. There is an urgent need for a device that can solve the above problems
