Abstract

The utility model provides a measuring scale for an erosion gully, which comprises two parts: a measuring scale for gully depth and a measuring scale for gully width, wherein both the measuring scale for gully depth and the measuring scale for gully width are provided with scales; the main body of the measuring scale for gully depth takes the shape of cylinder, the diameter of a spherical contact arranged at the bottom end of the main body is slightly bigger than that of the common contact to allow the contact to be conveniently nested into a central through-hole of the measuring scale for gully width; two edges of the measuring scale for gully width can be folded, the zero scale of the measuring scale for gully width is positioned in the center thereof and a through-hole is formed at the center part to ensure that the measuring scale for gully depth can be sleeved therein and can freely perform expansion and contraction. The measuring scale for an erosion gully has the benefits of simple structure, portability practical use, simple operation, low manufacturing cost, and easy popularization. Additionally, by adopting the measuring scale, the depth and the width of an erosion gully can be accurately and quickly measured; further the disturbance to the earth surface caused by the measurement can be reduced in order to ensure the accuracy of experiment and measurement, especially, the accuracy of continually observing the soil erosion can be particularly improved.

Description

The erosion groove dip stick

Technical field

The utility model relates to a kind of erosion groove dip stick, and it is used to measure soil erosion terrestrial erosion ditch section face, belongs to soil erosion test, monitoring field survey instrument.

Background technology

In present relevant soil erosion (distribution situation) test of carrying out, observation process, need to measure the soil loss amount of domatic diverse location in the sub-district, after (manually) rainfall, must measure the cross-sectional area of the erosion groove of domatic diverse location.Present widely used survey instrument still is traditional steel tape (ruler), very easily produces bigger error, the especially measurement of the erosion groove degree of depth when measuring and since observer's sight line can not with erosion groove edge level, so reading error is especially big; Secondly, existing instrument is big to the disturbance on the face of land, in erosion groove width measure process, steel tape can't be taken the dual-side edge that is put in erosion groove, when hand-held steel tape is measured, since gauger's hand tremble or hand breaks the original state of erosion groove, section is changed to some extent, strengthen the error that horizontal reading and even erosion groove cross-sectional area are measured.Make the correctness of soil loss amount observed result to guarantee, for the work of back brings puzzlement.Once more, existing tool work efficient is low, and erosion groove is more on the experimental plot, is the precision that improves observation, and the section that every erosion groove need be measured is also many, and the observation workload is quite big.

So, develop a kind of portable, practical, simple to operate, can the fast and accurate measurement erosion groove degree of depth and the survey instrument of width very necessary.

The utility model content

For overcome the deficiency that present traditional measurement tool steel tape measure (ruler) exists in measuring soil erosion terrestrial erosion ditch section face, the utility model provides a kind of dip stick, is combined by furrow width gage and ditch depth gage two parts.Can not only measure the furrow width and the ditch depth of erosion groove accurately, fast, and can alleviate the disturbance of artificial measurement to the face of land, the accuracy of improve experiment, measuring especially can improve the accuracy of continuation observation soil erosion.

Technical solution adopted in the utility model is: dip stick is made up of ditch depth gage and furrow width gage two parts, ditch depth gage and furrow width gage are equipped with scale, and ditch depth gage main body is cylindrical, and there is the spherical shape contact lower end, slightly larger in diameter conveniently is nested into the central through hole of furrow width gage; Furrow width gage both sides are collapsible, and " 0 " scale of furrow width gage is positioned at the center, and design has through hole in the center, are used for the ditch depth gage and are inserted in also retractable.

Erosion groove dip stick of the present utility model, simple in structure, the furrow width and the ditch depth of erosion groove can not only be measured accurately, fast, and the disturbance of artificial measurement can be alleviated the face of land, the accuracy of improve experiment, measuring especially can improve the accuracy of continuation observation soil erosion.It is portable, practical, simple to operate, and low cost of manufacture is convenient to penetration and promotion.

Embodiment

According to the furrow width and the raceway groove form of the erosion groove on the face of land that weathers, the utility model has designed one the erosion groove dip stick, and as shown in Figure 1, it is made up of two parts: the furrow width gage 2 of measuring the ditch depth gage 1 of ditch depth and measuring furrow width is used.Ditch depth gage 1 main body is cylindrical, and there is the spherical shape contact lower end, and slightly larger in diameter conveniently is nested into furrow width gage 2 and is difficult for dropping out, and an annular handle is fixed in the upper end.Furrow width gage 2 is designed to folding chi, and both sides can freely fold, and the gauger can be according to actual furrow width flexible operating.Ditch depth gage 1 and furrow width gage 2 are equipped with scale, and " 0 " scale of furrow width gage 2 is positioned at the center, and design has through hole in the center, and it is nested to be used for ditch depth gage 1.Ditch depth gage 1 freely stretches in the through hole of furrow width gage 2, and horizontal furrow width length is by " 0 " scale both sides the adding and obtain of reading respectively to the left and right; Vertically height is read at the scale that furrow width gage " 0 " scale place appears by the ditch depth gage.Reach the purpose of measuring erosion groove furrow width and ditch depth simultaneously, quickly and accurately.

Before measurement, furrow width gage 2 and ditch depth gage 1 are combined.Begin to measure, " 0 " scale of furrow width gage 2 is aimed at the raceway groove lowest part of erosion groove, make ditch depth gage 1 vertical with the raceway groove streamline.Again ditch depth gage 1 is extended the streamline position, bottom of contact contact raceway groove downwards, write down the furrow width reading respectively and the ditch depth reading gets final product.The furrow width reading is that furrow width gage 2 both directions are respectively to the scale sum at raceway groove edge; Ditch depth gage 1 is channel depth with " 0 " scale intersection of furrow width gage 2.

Because there is microtopography difference in the sub-district between the erosion groove, the design of furrow width gage is long, and some " embedded " formula erosion groove is inconvenient to measure.So the design, with the furrow width gage be designed to can two edge contractions form, when running into " embedded " formula erosion groove, two edge contractions can be measured.

When using end or carrying, furrow width can be surveyed chi and ditch depth and survey chi separately, reduce to take up room, be easy to keeping, avoid damaging.
