Building soil wind erosion measuring device and method

Abstract

The invention relates to a building soil wind erosion measuring device and method. The device comprises a central fixing rod which has a preset height and is vertically inserted in the ground, and theupper end of the central fixing rod is provided with a wind speed measuring instrument and a surface plant image collecting device; a plurality of mechanical arms are arranged, the ends of the mechanical arms are symmetrically arranged in an outward divergence mode with the central fixing rod as the center, and a plurality of fixing sleeves are arranged on the mechanical arms at equal intervals;a sand collecting box is of a wedge-shaped structure, the upper end of a crooked-chisel-type sensor probe is provided with a sand collecting cavity for containing wind erosion sand, the bottom of thesand collecting cavity is provided with a weighing sensor, and the lower portion of the sand collecting cavity is provided with at least two humidity sensors for detecting surface soil and a humiditysensor for underground soil. By means of the building soil wind erosion measuring device and method, the wind speed at a measurement position, the coverage information of surface plants, the weight ofthe wind erosion sand in a preset time period, the moisture of the surface soil and the moisture of the underground soil can be obtained, and research on a relationship between the wind erosion sandand the moisture of the surface soil and the underground soil is facilitated.

Description

technical field [0001] The invention relates to the technical field of construction soil, in particular to a construction soil wind erosion measurement device and measurement method. Background technique [0002] In the field of construction science and technology, the foundation is a very important subject. Often a building is in normal condition after completion. After a few years, due to changes in the foundation soil, the image cracks and sinks, or due to some high-rise deep foundation construction, pile digging, etc. Therefore, the measurement of soil wind erosion intensity is an important part of its research. The measurement of soil wind erosion intensity helps to prevent the subsidence and delayed changes of buildings or foundations, and helps to ensure that the foundation is stable and prevents building Collapse, reduce unnecessary troubles and accidents.

Problems solved by technology

[0003] At present, in the outdoor environment, due to the differences in soil wind speed, topography, and soil quality, it is difficult to study the problem of soil wind erosion in a vacuum. At present, soil wind erosion instruments at different points are usually used outdoors to collect wind erosion at different points For example, in the patent with the publication number CN202693257U, a field multi-point soil wind erosion detector is disclosed, including a host, an ultrasonic range finder, a bracket for the ultrasonic range finder, a solar power supply system, an ultrasonic anemometer, a gradient wind speed sensor, a temperature Composed of a humidity sensor, a rainfall sensor, a signal line, a fixed line and a bracket, the device is connected to 20 ultrasonic rangefinders at the same time through the host to measure the soil wind erosion depth, but the device in this patent is complicated and not portable, so it needs to be carried Various measuring equipment are used to measure wind erosion. In addition, this patent focuses on measuring the depth of soil wind erosion, and lacks research on the relationship between wind-eroded sandy soil, surface soil, and underground soil moisture. Therefore, it is urgent for those skilled in the art to provide a construction soil The wind erosion measurement device and measurement method have high portability, can quickly complete the measurement of wind erosion dust in an outdoor environment, clarify the relationship between wind erosion sand, surface soil and underground soil moisture, and provide a basis for soil wind erosion research
