Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.
Example 1:
the utility model provides a lining formula prestressed steel cylinder concrete pipe prestressed steel wire anchor, as shown in fig. 1 to 5, includes anchor body 1, prestressed steel wire 2, bellmouth steel ring 3, steel cylinder 4, steel cylinder inner wall concrete layer 5, anchor body 1 includes anchor pedestal 11 and clamp splice 12, anchor pedestal 11 is fixed on bellmouth steel ring 3, and anchor pedestal 11 comprises two cardboard and the fixed plate of two cardboard rear ends connections "U" shape structure, all be provided with the spout on the cardboard inside wall, the degree of depth of spout reduces gradually backward in the past, and the clamp splice 12 with spout assorted is inserted to every spout internalization, clamp splice 12 inboard is provided with the arc clamp groove along its length direction, prestressed steel wire 2 is located the arc clamp groove of two clamp splices 12.
