FIELD: engineering.
SUBSTANCE: invention relates to construction of engineering structures, for example, offshore platforms, namely to the structure of fastening a piling pipe support in the fixed offshore platform pre-fabricated base, and can be used both in construction of new structures and in repairing works or reconstruction of existing facilities. Disclosed is the design of fastening the piling pipe support in the sleeve of the attachment fitting of the stationary structure base using the method of untightening. Inside the piling pipe support, at least in the area of the pile metal deformation, caused by untightening, a rigid fixing element is formed from a solid composite material. The rigid fixing element is installed on the support surface formed in the piling pipe support perpendicular to its longitudinal axis.
EFFECT: reduced piling pipe support weight due to the use of piling pipes with a reduced wall thickness, reduced production time and reduced cost of installation and fixing the piles in the sleeves of the attachment fitting.
