MULTIPURPOSE BUILT-UP VESSEL (VERSIONS) AND METHOD OF ITS CONSTRUCTION (VERSIONS) Russian patent published in 2002 - IPC

FIELD: construction engineering, particularly, multipurpose built-up vessels used as surface, buried or underground tanks, basins, cesspools, storage pits of agricultural products, and methods of their construction. SUBSTANCE: multipurpose built-up vessel has walls from horizontal tubular members interconnected with one another, bottom, waterproofing layer located over vessel perimeter anchors and vertical ties which are prestressed and locked in wall upper part and connected with upper and lower tubular members. Ties are connected with anchors and passed through tubular members. Waterproofing layer is made in the form of cover or bag from synthetic film and located from external and/or internal side of walls. Method of construction of buries multipurpose built-up vessel assembly of wall part, deepening of wall assembled part with excavating of ground from its inside, sinking of assembled wall down to bottom of pit. Anchors with ties are sunk. Wall part is assembled of separate tubular member which are interconnected with one another and with ties. Ties are prestressed and locked. Waterproofing layer is brought to under assembled part of wall. Ground is excavated from inside over vessel perimeter and assembled part of wall is sunk to bottom. Level of sunk part of wall is equalized by tightening of ties, and remaining ground is excavated from inside. Operations are repeated until reaching design elevation. Lower waterproofing layer is laid on vessel bottom, its edge is brought to under wall and connected with waterproofing layer located from wall outside, and bottom formed. Method of surface assembled vessel includes construction of bottom and laying of waterproofing layer, assembly of wall from separate tubular members connected with ties which are prestressed and locked, and anchors are deepened. Ties are passed through members and connected with anchors. Waterproofing layer in the form of bag is additionally laid inside formed vessel. EFFECT: creation of vessel on site with any ground without use of special equipment and machines with minimal consumption of building materials. 29 cl, 18 dwg
