The invention discloses an integration structure of an omni-directional range reflection net and a steel-structure shelter. The integration structure comprises a reflection net base (1), a reflection net support (2), a reflection net (3), antenna arrays (4) and a communication machine room (5). The integration structure is characterized in that the reflection net base (1) is formed by a group of base pile foundations which are distributed at rectangular corner positions of an inner ring and an outer ring; the reflection net support (2) is an inner and outer ring lattice steel frame, inner ring supporting uprights (2.12) and outer ring supporting uprights (2.11) are connected through oblique supporting components (2.3), and the top part of the lattice steel frame is connected with overhang steel trusses (2.2) in central symmetry; the communication machine room (5) is the steel-structure shelter of which the bottom area is less than the enclosing area of the inner ring supporting uprights (2.12), and walking stairs (7) are arranged between the steel-structure shelter and the ground. According to the integration structure disclosed by the invention, not only are the base construction problems in traditional omni-directional range reflection net construction and the contradiction caused by cross construction between the machine room and the reflection net solved, but also the high-rise concrete machine room construction problems caused by high requirements at present and the whole structural stability problems are solved at the same time.
