fig. 2 is a schematic view of the front view cross-sectional structure of the present invention;

fig. 3 is an enlarged structural diagram of a region a in fig. 2.

In the figure: the device comprises a triangular iron 1, a bottom plate 2, an arch frame 3, an arch plate 4, a roller 5, a U-shaped clamp 6, a screw hole 7, a screw 8, a fixing block 9, a groove 10, a convex block 11, a scraping plate 12, a handle 13 and a limiting block 14.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 3, the present invention provides a technical solution: a multi-section assembled combined steel arch center under a downward-penetrating pipeline comprises triangular irons 1 and a bottom plate 2, U-shaped clamps 6 are welded at two ends of the bottom plate 2, the U-shaped clamps 6 are beneficial to limiting the distance between the two groups of triangular irons 1, the U-shaped clamps 6 are movably sleeved at the tops of the triangular irons 1, the two groups of triangular irons 1 are arranged and used as sliding rails, an arch frame 3 is installed at the top of the bottom plate 2 through bolts, an arch plate 4 is installed on the inner side of the arch frame 3 through bolts, and the arch plate 4 and the arch frame 3 are made of steel materials, so that the stability is improved;
