CONSTRUCTION METHOD AND FORTIFICATION STRUCTURE FOR ITS IMPLEMENTATION Russian patent published in 2023 - IPC E04H9/00 E04H15/22 

FIELD: military affairs.

SUBSTANCE: invention relates to the field of military affairs, namely to field fortification, and is intended to protect personnel from the direct and indirect effects of a shock wave from the explosion of conventional or nuclear enemy munitions. The fortification contains a housing in the form of a cylindrical high-strength hermetic soft shell. One of the spherical ends of the housing is equipped with a cavity valve and is a removable head. It is attached with a hermetic lock around the circumference of the cylindrical part. A frame of several soft toroids with a frame valve, united into the frame cavity by air ducts, is placed in the working cavity of the body and attached meridionally. The entrance is equipped with a protective and hermetic hatch and a conical shell with a lock and a communication window. Interior equipment includes: bunk seats, filtering and lighting equipment. For the erection of a fortification, a breakdown of the construction site is carried out, two pits are arranged. A pneumatic punch is placed on the bottom of the guide pit and oriented towards the receiving pit. Rolled up fortification with released gas is attached to a pneumatic punch. A pneumatic punch is launched, which arranges a horizontal well in the soil and draws the structure into it. The pneumatic punch is turned off, the structure is detached from it, and compressed gas is supplied through the cavity valve into the working cavity. The housing takes a cylindrical shape, compacts and lifts the soil, forms a protective soil layer above the structure. Compressed gas is fed into the frame cavity through the frame valve until the calculated overpressure is created in it and it is closed. The head is removed, auxiliary equipment is installed, a protective-hermetic entrance is mounted in place of the head.

EFFECT: increasing the camouflage and protective properties of a fortification by erecting a foundation pit without excavating, opening the earth's surface and disturbing the vegetative layer of the soil, which makes the planting of the structure on the ground invisible to enemy reconnaissance equipment.
