FOUNDATION FOR POWER TRANSMISSION LINE SUPPORT Russian patent published in 2024 - IPC E02D27/42 

FIELD: construction.

SUBSTANCE: invention relates to the field of construction of power transmission lines and can be used in the construction of foundations for supports of power transmission lines (PTL) with posts of foundation structures buried in the ground. Foundation for the power transmission line support contains a post with a head end buried into the ground, to which the base is connected by means of a connection unit. Base is made in the form of parallel lower crossbars located perpendicular to the post and attached to the opposite lateral sides of the post with their lateral sides, wherein said foundation is provided with top crossbars arranged above lower crossbars perpendicular to said crossbars and spaced apart from each other in symmetry about the post, wherein top crossbars are secured to post opposite lateral sides by their lateral sides. In the middle part of the lower crossbars there are through holes in the plane perpendicular to the direction of the lower crossbars, and a through hole is made in the post perpendicular to the lateral sides, to which the lower crossbars are connected. Connection assembly is made in the form of a long fastening element inserted into through holes in the lower crossbars and in the post and passing through the lower crossbars and the post and connecting them. In the middle part of the upper crossbars there are through holes in the plane perpendicular to the direction of the upper crossbars, and in the post perpendicular to the sides, to which the upper crossbars are connected, a through hole is made. Connection assembly is made in the form of long fastening element inserted into through holes in upper crossbars and in post and passing through upper crossbars and post and connecting them.

EFFECT: increasing bearing capacity of soil under support of post, due to use of elemental foundation consisting of separate spaced elements, which allows to distribute load on large volume of soil involved in operation.
