Abstract
On the water objects of the agro-industrial complex, low-pointed tubular culverts are widely used, the outlet head of which is made in the form of an expanding socket with checker-type energy absorbers. Only in the Moscow region such structures, built mainly in the 60‑70s of the last century, account for 76% of the total number of water system structures. The condition of 70% to 85% of them, depending on the region, is unsatisfactory: extinguishers, dam lining and apron are destroyed; excessive erosion and overgrowth of the discharge channel are observed. The results of hydrodynamic studies of the averaged and pulsating pressure on the downstream attachment elements and at the beginning of the discharge channel are presented. Based on the analysis of the nature of the flow pressure distribution for calculating quasi-static loading, predicting the total load on the fastening elements and choosing their optimal parameters, the influence of the flooding value of the hydraulic jump and the energy parameter on the pulsating component of the flow pressure and its frequency characteristics in relation to low-pressure reclamation and fishery tubular spillways, as well as road culverts.
