The invention provides a multifunctional benchmark for
engineering surveying, which relates to the field of
engineering surveying and mapping, and comprises: a benchmark
storage tube, a
position fixing rod, a protective installation sleeve, a
position fixing base, a fixed installation sleeve, a guide storage box, a winding swivel and a positioning support rod; the
position fixing rod is slidably connected to the inner side of the benchmark
storage tube; the protective installation sleeve is threadedly connected to the outer side of the benchmark
storage tube; the fixed installation sleeve is welded to the upper part of the benchmark storage tube; the position fixing base is fixedly connected to the outer side of the protective installation sleeve; the guide storage box is fixedly connected to the upper part of the benchmark storage tube; the winding swivel is rotatably connected to the upper part of the benchmark storage tube; the positioning support rod is rotatably connected to the outer side of the direction fixing bolt; the invention can protect the reflecting
prism, avoid the situation that the reflecting
prism collides with the ground and causes the reflecting
prism to be broken, ensure the progress of
engineering surveying, and solve the problem that the prism is easily broken after the benchmark is tipped over, thereby affecting the progress of surveying.
