CONSTRUCTIVE AND TECHNOLOGICAL SOLUTION FOR FOUNDATION OF INTERMEDIATE SUPPORT OF HIGH PILE WORK TYPE CONSTRUCTED IN TEMPORARY ENCLOSING STRUCTURE Russian patent published in 2023 - IPC E02D27/52 E01D19/14 E02B17/00 

FIELD: bridge construction.

SUBSTANCE: invention relates to the construction of supports for bridges and hydraulic structures erected in the waters of rivers, lakes, seas and reservoirs. The foundation of the intermediate support contains support body 2, having a foundation and an underwater part; at least one pile 3; grillage 1, supported by at least one pile 3 and configured to distribute the load from piles 3. When constructing the foundation of the intermediate support, temporary enclosing structure 5 is provided, containing a temporary cylindrical shell assembled from metal segmented panels. The segmented shield of temporary cylindrical shell 5 consists of at least one curved deck sheet, and on the outer side the deck sheet is reinforced with a system of longitudinal and transverse ribs and a flange with holes for bolted connections is provided along the contour of the deck. Temporary cylindrical shell 5 is immersed in the ground by an amount that exceeds the value of local erosion. The foundation contains cement pad 4, and the space between the bottom of cement pad 4 and mark 8 of the bottom of the reservoir inside temporary cylindrical shell 5 is filled with inert material. A method for constructing the foundation of an intermediate support is also proposed.

EFFECT: reducing the material intensity of the process of constructing the foundation of an intermediate support.
