This method of adjustment is simple and convenient, but the accuracy of the height position adjustment cannot be guaranteed, which may cause small errors in the measurement. A road construction measurement support frame includes a shell, and the peripheral wall of the shell is rotatably connected to a telescopic rod, and a mounting groove is provided on one side of the shell, and a through groove is provided on the inner wall of one side of the mounting groove. The utility model enables personnel to adjust the height position of the measuring instrument more accurately, avoids the problem of deviation in measurement data due to height position error, and provides strong bottom support for the measuring instrument.

However, in actual use, since the placing table is located on one side of the shell, the shell causes a certain obstruction to the use of the measuring device. At the same time, the prior art requires manual rotation of the screw rod to adjust the height of the measuring device, and the prior art is not convenient for adjusting the horizontal angle of the measuring device in actual use. For this reason, we provide a road construction measurement support frame to solve the above problems. Utility Model Content
