Purpose of the development: The invention is directed to providing personal signs on the exterior surface of the hatch in the form of a corresponding logo with the regulatory and passport data of reinforced concrete and the manufacture of a cover and hatch body with locking and locking elements that make it impossible to open the hatch by simply lifting the lid vertically and secure it securely in the hull, and also allow to arrange the hatch on one level with the surrounding surface of structures, earth, asphalt, etc.

Recommended application field: The invention relates to construction, in particular to elements that cover technological holes in structures, for example, wells, water supply, sewerage, heat and gas supply and other engineering structures.

Advantages over analogues: The disadvantage of metal hatches is their high cost and the possibility of kidnapping with subsequent surrender to scrap metal; polymer covers also have a high cost and for their manufacture special polymers and expensive forms are required; hatches made of reinforced concrete with metal rim covers have a significant metal content and the cost of the product.

The development stage readiness: Tested experimental exploitation order

Description of the development:
()
The reinforced concrete hatch consisting of a reinforced concrete casing and reinforced concrete lid is characterized in that the side surface of the hatch cover is a shell of an inverted truncated circular cone with locking and locking elements, and the inner side surface of the hatch body, in the form of an inverted truncated circular cone, has corresponding grooves for locating the locking-locking elements. On its external surfaces there is a logo of the location region of the client's hatch, the manufacturer with regulatory and passport data for the product of reinforced concrete. The cover is located in the hatch cover with the ability to rotate about the vertical axis with the help of a special device for mounting and dismantling works.
