By reserving a larger cavity under the unit-type auxiliary room, the wire pipes and water pipes can pass through the bottom of the unit-type auxiliary room, and personnel can enter through the reserved holes and the openable movable covers to facilitate the inspection and maintenance of the wire pipes and water pipes, thereby ensuring the normal use of the unit-type auxiliary room. The water retaining sill can prevent moisture or other liquids from penetrating into the cavity, thereby ensuring the safe operation of the wire pipes and water pipes, and ensuring the safety and convenience of use.

[0007] As a preferred technical means: the upper end of the opening is provided with steps along the periphery, the side walls of the steps correspond to the building surface layer, the step surface of the steps corresponds to the top surface of the concrete structure, the movable cover is provided on the step surface of the steps, the building surface layer is provided with a first angle steel as a reinforcement member along the periphery of the steps, and the concrete structure is reinforced by a second angle steel on the step surface and the upper end of the side walls of the opening.

The upper end of the round steel is connected to the second angle steel to improve the bearing capacity of the second angle steel.

[0009] As a preferred technical means: the concrete structure is embedded with horizontal steel mesh and vertical bolts, the bolts are arranged in the concrete structure between the floor and the opening, the bolts pass through the steel mesh downwards and are welded and fixed to the steel mesh.

The combination of the waterproof layer and the leveling layer not only provides a flat surface, but also helps to enhance the stability of the structure. The leveling layer can fill in the tiny gaps or unevenness that may exist in the waterproof layer, thereby forming a more uniform and stable protective surface, preventing damage to the waterproof surface layer due to collisions and trampling, and improving safety.

[0012] As a preferred technical means: a filling structure layer is provided on the periphery of the enclosure. The filling structure layer tightly surrounds the periphery of the enclosure, effectively enhancing the structural stability of the enclosure.
