METHOD OF BLOCK-MODULAR CONSTRUCTION OF STRUCTURES IN PITS Russian patent published in 2024 - IPC E04H9/12 

FIELD: construction.

SUBSTANCE: invention is intended for the open-pit construction of buried structures for various purposes, including the field of fortification, namely the construction of military camps and other military infrastructure facilities. To build a structure using the indicated method, several block modules, manufactured in a factory using progressive operations, with saturation with equipment and devices, but not less than two, are placed in one tier, the block modules are connected to each other by passageways made of reinforced concrete, and along the slopes of the pit they form several input turns, but not less than two, connecting the block modules with the surface of the earth. All block modules and walk-through walls are covered with waterproofing along the outer surface, placed on a foundation slab, made of reinforced concrete and attached to the foundation slab using anchors, drainage channels are created along the perimeter of the foundation slab and connected to a water-reducing installation located on the ground surface, after this the pit is backfilled to the level of the ground surface. At the same time, the passageways are equipped with protective-sealed doors. After connecting the block modules to each other and attaching them to the foundation slab using anchors on top of the block modules, reinforcement outlets are installed, four outlets for one reinforced concrete structure, then the second reinforced concrete slab is poured, after the second reinforced concrete slab has gained the design strength, the creation of drainage channels along the perimeter of the foundation slab and connecting them with a water-reducing installation, temporary formwork is assembled for the installation of reinforcing structures made of reinforced concrete and for the installation of two vertical shaft entrances to the outer block modules located on the left and right sides of the structure, respectively. After backfilling the pit to the level of the ground surface, concreting of two vertical mine entrances and reinforcing structures made of reinforced concrete is carried out, and then, after the design strength has been achieved with concrete of two vertical mine entrances and reinforcing structures made of reinforced concrete, the third reinforced concrete slab is concreted, followed by the construction of a ground frame-panel building.

EFFECT: providing the possibility of rapid evacuation of personnel by constructing a vertical mine entrance and increasing the survivability of the underground structure by installing protective-sealed doors between the block modules, which allows for the autonomous functioning of a separate block module in the event of damage to the remaining block modules of the structure.
