Abstract

FIELD: hydraulic engineering construction. SUBSTANCE: shore-protective construction has blocks with projections in their lower part. The blocks are placed along shore ramp with step wise rows. The blocks overlap joints in the plane. Additional blocks are placed over reservoir bottom perpendicular to shore ramp. EFFECT: shore protection. 3 dwg

Description

 The invention relates to protective fastenings of slopes of hydraulic structures from erosion by water flows, including self-protection of the structure from erosion.
 The well-known protective fastening of the slopes of hydraulic structures is made in height from blocks separate with a through hole, with protrusions in the lower and upper parts for joint adhesion of the blocks to each other without reliable adhesion to the soil of the coastal slope, and the structure itself is not protected in the lower part from washing out by water flows.
 The aim of the invention is to increase the reliability, stability, reducing the load from exposure to soils of the coastal slope and groundwater, the greatest adhesion to the coastal slope, reducing material consumption and reducing the complexity of the construction. By damping the speed of the water flow of the counter-mounted monolithic blocks and the most step-by-step design of the shore protection structure over the entire width of the block, washing out of the coastal slope and the device itself is prevented.
 The design of the shore protection structure significantly expands the water area in its height without additional costs, since there is no need for blocking each other. This goal is achieved by the fact that in the well-known protective fastening of the slopes of a hydraulic structure, the coastal slope is protected by blocks in stepped rows with the dressing of the rows lying with each other overlying with the protrusions with laying the steps on the slope without reliable adhesion to the soil of the base. The lower row of first-stage blocks at the base of the coastal slope with their protrusion cannot be a reliable foundation and an emphasis against the shift of the entire stepped structure without a reliable foundation that can hold the entire structure and prevent undermining of the base of the slopes' protective fastening. The proposed coastal protection structure, which is made of separate monolithic blocks having pyramidal trihedral piles located along the coastal slope in stepped rows at the bottom of the grillage, is capable of eliminating these drawbacks.
 The overlapping of the joints in the plan between the blocks of the lower row located above the lower row was performed without superimposing the blocks above on the blocks below, which allows using the entire width of the block in steps without additional costs.
 Piles of a monolithic block not only contribute to reliable adhesion to the soil of the coastal slope, but also do not interfere with the filtration of ground (underground) waters. A buttress set of monolithic blocks along the bottom of the reservoir at the base of the slope of the bottom row of monolithic blocks serves as a reliable stop and at the same time dampens the speed of the water flow along the shore protection structure, preventing the undermining of the structure, and the structure itself, which has pile engagement with the soil of the bottom of the reservoir and the coastal slope, is not washed out.
 Figure 1 shows a section of a shore protection structure; figure 2 side view of the monolithic block; figure 3 monolithic block in isometric view.
 The shore protection structure contains monolithic blocks 1, installed in rows and buttresses at the joints of the lower row of the 1st stage, grillage-2 and trihedral pyramidal piles 3.
 Assembling the shore protection structure begins with laying the first lower row of steps along the base of the coastal slope, the second and each subsequent row (step) are laid so that the upper monolithic block overlaps the joint of two adjacent blocks of the lower row. Laying of monolithic blocks is carried out by pressing into the soil of the base, the guides are the plane of the pyramidal piles, made at the same time with the side surface of the block. The height of the step corresponds to the height of the grillage of the monolithic block. Against the joints of monolithic blocks of the 1st row (1st stage), installed at the base of the coastal slope, monolithic blocks are installed buttresses along the bottom of the reservoir by pressing piles into the soil of the bottom of the reservoir.
 The presence of pile adhesion to soils of the base of the slope and the bottom of the reservoir makes it possible for the structure to take increased active soil pressure more efficiently than existing structures, groundwater filtration has no barriers. The efficiency of the structure is increased in opposing the erosion effect of water flows due to the presence of buttress devices, pile foundations and free steps having the width of a monolithic block. Access to the reservoir is free on the steps, as special descents are not required.
