The top of the silo is generally in a cone structure, the thickness of the top of the silo is generally about 1 m, and the thickness of the top of the silo is thicker. The outer contour surface of the silo top of the silo with a concrete structure is of a hemispherical structure, but the integral three-dimensional shape of the silo top is of an arc body shape which is convex outwards and concave inwards, wherein the arc body shape can be less than or equal to 1/2 hollow sphere, and the silo is like a half-cut basketball. The conventional construction method of the concrete structure silo and the silo top thereof comprises the following steps: after the construction of the side wall of the silo is finished, a vertical bent frame consisting of cross rods, vertical rods and inclined support rods is erected in the silo, a horizontal steel structure support is erected on the wall of the silo, a formwork of the silo top, binding steel bars and one-time concrete pouring are arranged on the vertical bent frame to form the silo top with the thickness, and the bent frame and the formwork are detached after the concrete strength of the silo top meets the requirement. According to the method, as the silo top formed by pouring concrete at one time is thick, a vertical bent frame needs to be built in the silo to support the bearing capacity of the concrete before the silo top is formed by pouring the concrete and the concrete meets the strength requirement. The construction period of the vertical bent frames is long, the labor cost of the construction of the vertical bent frames is high, and the material cost of the vertical bent frames is high; the vertical bent frames can collapse or the rod pieces fall off to injure construction operators to cause safety accidents in the dismantling process, the vertical bent frames occupy the operation space in the top of the silo, the interior of the silo interferes with the top of the silo, and cross construction operation is not convenient. In addition, as the top of the silo is constructed by pouring concrete at one time in an ultra-thick and ultra-high environment, the built vertical bent is likely to cause great safety accidents such as collapse and the like due to the fact that the bearing capacity is not enough to support the gravity of concrete pouring, and great safety risks are achieved.
