Abstract
The utility model discloses a kind of guiding ruler gradient measurer, described measuring instrument is right-angle triangle, comprises crossfoot in horizontal direction, perpendicular chi in vertical direction and long chi; Be flexibly connected by rotating shaft between described crossfoot with long chi; Described perpendicular chi and long chi are bolted to connection; Described crossfoot and perpendicular chi centrally line have isometric wide rectangular through holes; Described crossfoot and perpendicular chi are flexibly connected by the bolt through two through hole, and the diameter of described bolt is slightly less than the width of through hole; Described perpendicular chi is equipped with vertical below through hole.The utility model is simple to operate, one people gets final product light complete operation, easy to make, use flexibly, be easy to grasp, can judge whether the gradient meets the requirements according to the swing of vertical, for the engineering project measurements such as dam body unwrapping wire determination slope angle, the dam slope checking partial gradient provide foundation, substantially increase work efficiency.
Description
Technical field
The utility model relates to a kind of guiding ruler gradient measurer, belongs to surveying instrument field.
Background technology
The whole slope of dam slope requires that the gradient is consistent, surfacing, and do not rise and fall, form a plane, seem simple, reality is very difficult, and unskilled labor author only rests in the work of ground grading, for inclined-plane, and the embarrassment of having no way of doing it a little.The method of the current measurement gradient is all adopt tape measurement and spirit-leveling instrument method.Tape measurement is simple, intuitive comparatively, but affects large by artificial estimation, and measuring accuracy is lower; Although the data that spirit-leveling instrument method records are comparatively accurate, operating personnel need to grasp through professional technique training ability reality, and the personnel that take are more, measure efficiency low, and the expensive impossible comprehensive configuration of instrument price.In addition, need after measurement through mathematical computations, bring a lot of trouble and inconvenience to testing staff, and can not accurately know the direction of resultant gradient.Use the principle that alternate interior angle is equal, invent a kind of specially for the measuring instrument of dam body whole hill start slope unwrapping wire with local unwrapping wire.In ground grading, operate surveyor's staff equally simple for measuring dam slope time image for this measuring instrument.
Summary of the invention
Technical problem to be solved in the utility model be to provide a kind of structure simple, be easy to operation, be mainly used in the measuring instrument on the whole slope of dam body.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme: a kind of guiding ruler gradient measurer, is characterized in that: be right-angle triangle, comprises crossfoot 3 in horizontal direction, perpendicular chi 4 in vertical direction and long chi 1; Be flexibly connected by rotating shaft 2 between described crossfoot 3 with long chi 1; Described perpendicular chi 4 and long chi 1 are bolted to connection; Described crossfoot 3 and perpendicular chi 4 centrally line have isometric wide rectangular through holes; Described crossfoot 3 and perpendicular chi 4 are flexibly connected by the bolt through two through hole, and the diameter of described bolt is slightly less than the width of through hole; Described perpendicular chi 4 is equipped with vertical 5 below through hole.
The utility model is simple to operate, one people gets final product light complete operation, easy to make, use flexibly, be easy to grasp, be easy to judge whether the gradient meets the requirements according to the swing of vertical, for the engineering project measurements such as dam body unwrapping wire determination slope angle, the dam slope checking partial gradient provide foundation, substantially increase work efficiency.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
As shown in Figure 1: 1 long chi, 2 rotating shafts, 3 crossfoots, 4 perpendicular chi, 5 verticals.
Embodiment
Contrast Fig. 1 uses step to be described further to operation of the present utility model:
Embodiment one: a kind of guiding ruler gradient measurer, is characterized in that: be right-angle triangle, comprises crossfoot 3 in horizontal direction, perpendicular chi 4 in vertical direction and long chi 1; Be flexibly connected by rotating shaft 2 between described crossfoot 3 with long chi 1; Described perpendicular chi 4 and long chi 1 are bolted to connection; Described crossfoot 3 and perpendicular chi 4 centrally line have isometric wide rectangular through holes; Described crossfoot 3 and perpendicular chi 4 are flexibly connected by the bolt through two through hole, and the diameter of described bolt is slightly less than the width of through hole; Described perpendicular chi 4 is equipped with vertical 5 below through hole.In actual applications, known slope angle angle, by regulating the length of crossfoot 3 and perpendicular chi 4, makes the angle of long chi 1 and crossfoot 3 equal slope angle angle, and erect measuring instrument, it is domatic that dam body is close to by long chi 1, can determine to put slope or closing slope by the position of vertical 5.If vertical 5 is partial to the left side of perpendicular chi center line, then dam slope is more slow, and slope angle angle is less than normal, needs closing slope; If vertical 5 is partial to the right of perpendicular chi center line, then dam slope is comparatively anxious, and slope angle angle is bigger than normal, needs to put slope; Only have vertical 5 to overlap with perpendicular chi center line, then slope angle angle is the slope angle angle of designing requirement.
