HYDRAULIC STRUCTURE WITH VERTICAL PROFILE ON PILE BASE AND METHOD OF ITS ERECTION Russian patent published in 2015 - IPC E02B3/06 E02B17/02 

FIELD: construction.

SUBSTANCE: method of construction of the structure includes the installation of the metal conductors (MC) and vertical piles with their subsequent immersion into water area bed ground, supply of concrete mix for formation of the bearing supporting framework in the form of the monolithic concrete block (MCB) 8. From the coast towards the high sea on underwater coastal slope into the ground 10 of the water area bed 11 on the structure axis MCs are installed permanently one by one which for the whole period of construction and operation of the structure are fixed. At first the first MC is permanently installed with external metal protection in the form of the flexible rod holding device (FRHD) forming internal space of MC it is filled with large stones or concrete figured elements 16, then at the distance 0.4-0.6 m from its external perimeter the formwork is installed. The concrete mix is supplied into the internal space fenced with the formwork and the first MC is made monolithic, except internal cavity of its vertical metal pipes (VMP) 2. The concrete mix is held until curing, and after achievement by concrete of pre-set strength in the internal space, fenced with formwork, the first monolithic concrete block (MCB) 8 is formed with the top mark 0.6-2.0 m with reference to the sea level which is a structure component. From the surface of the first MCB 8 through internal cavities of VMP 2 one by one the anchoring piles 7 are installed, moving them through the body of the first MCB 8 after its erection, and under it the anchoring pile base is formed which fixes the first MCB 8 from movement by wave influence after its erection. The top head part 12 of anchoring piles 7 in equal in strength manner and rigidly are fixed in the internal cavity of VMP 2 with the internal surface of these pipes by means of plate-type metal inserts. The gap between the piles and internal surface of metal pipes, and also head parts of piles in places of their fixing in internal cavities of VMP 2 is filled with fine-grained concrete to provide stability of MCB 8. At the distance 0.4-0.6 m from the first MCB 8 the following second MC is installed on water area bed with external metal fencing in the form of FRHD. The named operations of the method are performed similar to the construction of the first MCB 8. The second MCB 8 is formed with the top mark 0.6-2.0 m with reference to sea level. In the same sequence the construction of the following MCB 8 is performed until formation of the row of the monolithic concrete blocks 8 installed on the anchoring pile base and which are the components of the whole hydraulic structure with vertical profile. In the inverse sequence, starting from the last in the row MCB 8 installed on the anchoring pile base towards the coast the concrete or ferroconcrete superstructure 19 is erected on which if necessary the storm wall 20 is installed, and on the underwater coastal slope from various grounds, including from easily washed away incoherent soil, the stationary hydraulic structure with vertical profile on the anchoring pile basis is formed.

EFFECT: improvement of bearing ability of the structure, its strength, reliability and resistance to washout of base ground, and to storm impact.
