METHOD TO INSTALL UNDERGROUND VERTICAL CYLINDRICAL RESERVOIRS Russian patent published in 2013 - IPC E02D27/38 

FIELD: construction.

SUBSTANCE: method to install underground vertical cylindrical reservoirs consisting in digging a pit for a reservoir, installation of a foundation, installation of the reservoir into the foundation and its fixation to the foundation, testing of the mounted reservoir and filling of the space between the reservoir and the pit. Travelling forms are installed on the bottom of the pit on top of the reservoir, and the forms are made in the form of a cylinder without a base with a diameter defined in accordance with the expression d=d + 0.4m, where d - diameter of forms, d - reservoir diameter, m, with elements for gripping and moving of the forms in the upper part. Filling is carried out by layerwise filling of the space between the forms and the reservoir with sand, and between the forms and the pit - with soil with subsequent ramming of each layer. Then repeated filling of the forms is carried out with sand, and the pit is filled with soil, after moving of the forms upwards along the reservoir until full filling of the pit and withdrawal of the forms.

EFFECT: higher cost-effectiveness of installation of underground vertical cylindrical reservoirs, reduced material intensity and labour intensiveness of construction.
