Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, and in particular to a building foundation soil particle analysis and detection device for engineering supervision. BACKGROUND

[0002] Currently, in building engineering, the stability of the foundation directly affects the safety of the entire building. In order to evaluate the bearing capacity and compression resistance of the foundation, detailed physical and chemical analysis of the foundation soil is usually required. Among them, soil particle analysis is one of the most basic and important links.

[0003] The existing soil particle analysis methods mainly include sieve analysis method, sedimentation method, etc. Although these methods can provide certain data support, there are still many limitations in actual operation.

[0004] Sieve analysis method: soil samples are classified and screened by standard sieves with different aperture sizes, so as to obtain the mass proportion of soil in each particle size range. The advantage of this method is that the equipment is simple and the cost is low, but the disadvantage is that it takes a long time and is easily affected by human factors, resulting in inaccurate results.

[0005] Sedimentation method: soil samples are suspended in water, and the mass percentage of each particle size is determined according to the sedimentation velocity of different size particles in water. The advantage of this method is that it can quickly obtain relatively accurate data, but the equipment is complex, the maintenance cost is high, and the water quality requirement is high.

[0006] Other auxiliary methods: such as laser scattering method, microscope observation method, etc. These methods can improve the measurement accuracy, but the equipment is expensive and not suitable for large-scale popularization and use.

[0007] Defects of prior art: although the above methods have their own advantages, there are also obvious shortcomings. For example, the sieve analysis method is greatly affected by manual operation, and the error is difficult to control; the sedimentation method relies on complex instrument equipment, and the operation is complicated and the cost is high; other auxiliary methods can improve the accuracy, but due to the high price of the equipment, it is difficult to popularize. Therefore, it is urgent to develop a soil particle analysis and detection device with high efficiency, low cost and easy operation to meet the needs of modern building engineering.
