Description

A kind of simple multi-purpose gradiometer for water conservancy construction

Technical field

The utility model is related to a kind of simple multi-purpose gradiometers for water conservancy construction, are mainly used in dykes and dams irrigation canals and ditches engineering Side slope site operation and inspect supervision and management by random samples at any time.

Background technology

Instrument and the method for being applied to hydraulic engineering slope measuring currently on the market are many, but can be used for construction site technology Personnel carry out at-once monitor to dykes and dams irrigation canals and ditches side slope, not only simple and fast but also the method with specified accuracy and few, some utilizations Instrument of surveying and mapping is calculated, and needs several talents that can complete, inefficient, the portable instrument that market has, because its length only has 20 Centimetre or so, it is confined to very short slope surface length range, it is also necessary to smooth slope surface, it is difficult to the convex-concave slope compared with large span Face carries out quick slope detection, can not be applied to construction personnel scene frontier inspection and survey side guiding construction.

Invention content

To solve to carry out the difficulty of slope checking in the construction of hydraulic engineering slope surface at any time, overcome with existing measuring instrument and survey Amount method carries out the cumbersome defects such as low with efficiency when engineering slope measuring, and the utility model designs a kind of water conservancy construction that is used for Simply multi-purpose gradiometer, it is easy to use, the construction of slope surface can immediately be instructed, correct slope at any time with the direct-reading engineering gradient Plane inclination, easy to operate reliable, to speeding up the work, improving construction quality has great help.

The technical solution of the utility model is as follows：

It is a kind of to be mostly used gradiometer for the simple of water conservancy construction, include：Gradiometer holder, plummet and perpendicular, reading Dial.Gradiometer holder is to be made two mutually perpendicular rulers with high-quality aluminum alloy materials, length be respectively 0.5 meter and 0.866 meter, rivet clasp forms right angle at ruler zero graduation endpoint, and the bipod that taper forms instrument is made in the other end of ruler.It hangs down Sufficient place set there are one suspension perpendicular small hook；One anchor line (string) plummet, the upper end of line be suspended on instrument support two are hung down mutually On small hook at the intersection point of straight ruler；It is arranged one in the position of 0.3 meter of the intersection point apart from instrument support to hang down with instrument support Foot is the circular arc fan-shaped panel in the center of circle, marks three row scales along circular arc direction on panel, and scale is to use angle respectively, degree, numerical value, The slope surface gradient that ratio denominator indicates.The numerical value positioning for marking 0 ° of -90 ° of scale of the ranging from angle of gradient of scale, with the meter of geometry Calculation method has ∠ ABE=∠ FCD according to figure.

When measuring the angle of gradient using the utility model, the long right-angle side that 0.866 meter of hand-held support makes 0.5 meter of short right angle While towards slope surface top, keeps the direction of instrument support consistent with the direction of slope surface to be surveyed, so that instrument bipod is landed, perpendicular is hanged It hangs on the small hook of instrument support, the reading that reading perpendicular intercepts on dial after plumb line stabilization, which can be obtained, uses angle The slope surface gradient that degree, numerical value or ratio denominator indicate.

This simple multi-purpose gradiometer also acts as the Vertical surveyors' staff of construction of hydro project, and the vertical phase of engineering is instructed for detecting Hand over the construction of facade；Range measurement is can also be used to, the distance of two feet of gradiometer holder is precisely 1.0 meters, holds the gradient Instrument holder is landed with a foot, allows another foot to land along measurement direction, then using front foot as axis, and the rear foot is turned to front, Successively forward advance count number of revolutions, less than a ruler part with right-angle side ruler delineate measure, you can measure line segment away from From.

The utility model has the beneficial effects that：

A kind of simple multi-purpose gradiometer for water conservancy construction solves in the construction of hydraulic engineering slope surface and carries out the gradient at any time The difficulty of verification overcomes cumbersome low with efficiency equal scarce when carrying out engineering slope measuring with existing measuring instrument with measurement method Fall into, in water conservancy construction, application method is simple and convenient and easy to study, at a glance can, the direct-reading engineering gradient refers to the construction of slope surface immediately It leads, corrects slope surface gradient at any time, easy to operate reliable, to speeding up the work, improving construction quality has very big help.

Description of the drawings

The utility model is further illustrated with reference to the accompanying drawings and examples.

Fig. 1 is the principles of the present invention figure.

In attached drawing, 1. gradiometer holders, 2. gradient reading dials, 3. plummets and perpendicular, 4. tested engineering slope surfaces.

Specific implementation mode

Referring now to attached drawing, it is described in conjunction with the embodiments as follows：

In attached drawing, a kind of simple multi-purpose gradiometer for water conservancy construction includes gradiometer holder 1, gradient reading dial 2, plummet and perpendicular 3.Gradiometer holder 1 is made of high-quality aluminum alloy materials, is that two rulers are orthogonal in intersection point Locate rivet clasp, two ruler length are respectively 0.5 meter and 0.866 meter, at the zero graduation endpoint of two rulers rivet clasp formation right angle, ruler it is another The bipod that taper forms instrument is made in one end.The small hook of suspension perpendicular, the upper end of plummet and perpendicular 3 there are one being set at intersection point It is suspended on the small hook at the intersection point of two mutually perpendicular rulers of instrument support；In 0.3 meter of the intersection point apart from instrument support Position be arranged one using instrument support intersection point as the circular arc fan-shaped panel in the center of circle, i.e. gradient reading dial 2, along circular arc on panel Direction marks three row scales, and scale is the slope surface gradient indicated with angle, numerical value, ratio denominator, respectively gradient angle respectively 0 ° -90 °, the tangent value of gradient numerical value, that is, angle of gradient, the numeralization of the gradient ratio denominator, that is, gradient make denominator value when molecule is 1.
