As shown in fig. 1-7, an explosion-proof pressure release wall of assembled transformer substation, includes wall spare board and the steel column that is located wall spare both sides, wall spare is including the continuous reverse shoe-shaped aluminum alloy contour plate who buckles and is the shoe-shaped cavity, and aluminum alloy contour plate both ends and steel column laminating have run through the wall reinforcing bar in shoe-shaped aluminum alloy contour plate middle part, the both ends of wall reinforcing bar are fixed in the steel column respectively, it has buffer material layer and the light concrete layer of fibre to fill to the outside by the bottom in the shoe-shaped cavity of shoe-shaped aluminum alloy contour plate.
In this embodiment, the horseshoe-shaped aluminum alloy contour plate, which is used as a framework of the explosion-proof pressure relief wall, can deform to a certain extent to relieve pressure when bearing an explosion impact load, and has a limiting effect on a fiber light concrete layer with a back explosion surface enhancing the rigidity of the wall, so that the fiber light concrete layer is prevented from being easily separated from the wall. The horseshoe-shaped aluminum alloy contour plate is also used as a template for pouring a buffer material layer and a fiber light concrete layer during construction;
in a preferred embodiment of the invention, the buffer material layer and the fiber light concrete layer are filled from the bottom to the outside in the hoof-shaped cavity. The buffer material layer is rigid polyurethane foam. The aluminum alloy contour plate of the front explosion surface can deform to extrude the buffer layer to dissipate energy and damp, and the fiber light concrete layer of the front explosion surface can displace to extrude the buffer layer to dissipate energy and damp; the fiber light concrete layer is rubber fiber foam concrete, has better ductility and is not easy to crack when resisting impact load, and the weight of the wall body is greatly reduced;
