A simple and easy multi -purpose gradiometer for water conservancy construction

The utility model provides a fan -shaped panel of circular arc, the domatic slope of mark on the panel that the high -quality aluminum alloy ruler that a simple and easy multi -purpose gradiometer forwater conservancy construction, support used two orthogonal, length to be 0.5 meter and 0.866 meter is respectively made at the intersection point anchor of department, and the plummet hangs in intersection point department, and set up one in the position of 0.3 meter intersection point apart from equipment stand and use the equipment stand intersection point as the centre of a circle. In dykes and dams irrigation canals and ditches constructions, to arrange it on domatic in, the reading that reads plumb -bob line intercepting on the calibrated scale after the plumb line is stable can obtainthe domatic slope. The distance of two feet of equipment stand is 1 meter, can be used for finding range. The utility model provides a difficulty of carrying out slope check -up at any time in the domatic construction of hydra
