This utility model relates to the field of casual shoe technology and discloses a highly wear-resistant casual shoe, including a main shoe body. A main shoe sole is fixed to the bottom surface of the main shoe body. The main shoe sole includes an EVA outsole pad, and a frame pad is connected to the top surface of the EVA outsole pad around its perimeter. A bottom groove is formed inside the top surface of the EVA outsole pad, and a midsole pad is adhered to the top surface of the bottom groove. The bottom of this utility model consists of an EVA outsole pad and a TPU anti-slip pad layer. The EVA outsole pad provides rebound and shock absorption, improving wearing comfort, while the TPU material of the TPU anti-slip pad layer itself provides high anti-slip and wear resistance. Its friction and force mainly act on the protruding structures such as the anti-slip heel and anti-slip stripes. When the anti-slip stripes are under force, each group of anti-slip stripes is connected by longitudinal stripes to form a structural rib mesh, reducing the deformation caused by force, thereby ensuring the stability of the bottom anti-slip and wear-resistant structure. At the same time, the use of TPU material ensures high wear resistance.

The present application belongs to the field of bridge structure, and provides a curved arm grating type deck structure, which comprises steel bars implanted in a bridge deck slab, a concrete curved arm deck, a transverse diaphragm beam under the deck, and a ground beam at the rear end of the deck. The bridge will shrink under the effect of temperature change, and placing a deck that can provide deformation between the bridge and the road surface can form a seamless bridge.
