HYDRAULIC STRUCTURE FOR WATER INTAKE FROM THE SPRING Russian patent published in 2017 - IPC E02B9/04 E03B3/06 

FIELD: construction.

SUBSTANCE: hydraulic structure for water intake from the spring contains the tank 2, installed in the water bearing bed, made in the form of the stilling chamber 1 with the reversed filter 3 and the water intake hole 4. The waterproofing layer 6 of the required height is located around the chamber 1. The clay retainer 5 is made from above the chamber 1. The stilling chamber 1 contains the mine water outlet 7, whose head is made with L-shaped shield 8 towards the chamber 1 bottom. The end part of the mine water outlet 7 has the threshold 10 with the shelf 11 and the outlet pipe 12. The head of the outlet pipe 12 is fastened by means of the flexible corrugated coupling 13 to the pipe 14, in the upper part of which there is the hinge 20, through which the pipe 14 is connected to the remote rod 15, designed for fixing the pipe 14 free end at the required height in relation to the mine water outlet 7 input head with L-shaped shield 8. The pipe 14 is installed in the tank 16 and with one end is rotatably mounted on the outlet pipe 12. The free end of the pipe 14 has the support 17 in the bottom part, whose height is selected from the estimation, that in the lowest position of the pipe 14 its free end is at the level of the wastewater pipeline 18 with shield 19. There are latches 21 at the rod 15, intended for fixation of the relative positions of the chamber body 1 and rod 15. The water flow, entering the outlet pipe 12 at the end of mine water outlet, is damped by the threshold 10 with the slab shelf 11 and fills the outlet pipe 12 with full section, that creates the favourable conditions for alignment of flow intensities in the pipe 14. There appeared the backwater in the mine water outlet, when lifting the pipe 14 upward, the water level in the chamber 1 is stabilized, the wave process from the water surface disappears, taking into account the work and L-shaped shield 8, located on the head at acute angle to the outer wall of the mine water outlet 7. Such a mode of spring water intake from the aquifer allows to provide the constant work of structure in the offline mode on the underground spring water intake.

EFFECT: increase of the efficiency and uniformity of flow allocation along the width of the tank as a whole and reduction of bottom speeds to get more clean water at the entrance to the discharge pipeline, structure simplicity and reliability.
