In such scheme, the described built-in fitting threaded hole degree of depth is greater than the web member spiro rod length.
In such scheme, described built-in fitting is cylindric, and its fixed orifice is coaxial with cylindric built-in fitting, is provided with flat bayonet socket or flat step at cylindric built-in fitting outside surface.
In such scheme, described web member can be a coupling shaft, and its connecting portion is positioned at coupling shaft one end, and coupling shaft is provided with the plane of orientation that is connected with measurement mechanism.Described web member can also be for connecting double-screw bolt, and its connecting portion is positioned at and connects double-screw bolt one end, and connecting the double-screw bolt other end is the double-screw bolt that can cooperate with surveying instrument.
In such scheme, described plug is made up of end cap, thread plug, and end cap is coaxial with thread plug, and the end cap diameter is greater than built-in fitting location unthreaded hole diameter, and thread plug cooperates with the built-in fitting threaded hole.
In such scheme, between the end cap of plug and thread plug, be provided with spacing ring, the diameter of this spacing ring less than location unthreaded hole diameter greater than the thread plug diameter.
Need only the fixed orifice that web member is screwed in embedded part when the utility model uses, rotating prism aiming total powerstation can the centering leveling.
The utility model is simple in structure, connection is convenient, and the measuring operation simple and fast has avoided burying concrete obstruction when surveying, and has overcome the influence that tiny dust is fallen into.Especially the fixed orifice of built-in fitting adopts the combination of threaded hole and location unthreaded hole, its fixed performance and measuring accuracy are improved greatly, evaded the error accumulation that produces by labyrinth, simultaneously built-in fitting can according to field condition horizontal, vertical comprehensive imbed in wall, the post can, can not produce and invade boundary's influence railway.
