The utility model relates to a tripod for engineering mapping, three the same telescopic stabilizer blades connecting through a pivot including the bottom of workstation and workstation, the bottom ofstabilizer blade is through no. Two pivot connection gasket feet, the top of workstation has the spirit level, the stabilizer blade includes stabilizer blade and lower stabilizer blade, and the middle part of going up the stabilizer blade is equipped with one, and the upper portion of lower stabilizer blade is equipped with two circular pore along the rectangular shape through -hole of last stabilizer blade length direction, and two bolts pass rectangular shape through -hole and two circular pore respectively to it is fixed through setting up at the nut at bolt both ends. Compared with the prior art, the utility model discloses set up the spirit level, can guarantee that the horizontal stand was in horizontal position before the survey and drawing to ensure mapping precision, and the special setting through the stabilizer blade, the stabilizer blade also can be known and transfer how much length that adjustment efficiency is higher very easily to length that can very easy regulation stabilizer blade.
