Concrete block of revetment

Abstract

The invention discloses a concrete block of a revetment and belongs to the field of water conservancy projects. The concrete block comprises a base plate. A wave reducing slope is connected to the back surface of the base plate, the wave reducing slope is composed of one or more arc-shaped structural segments and the gradient of the wave reducing slope is decreased gradually from top to bottom. Aburied pile is connected to the front surface of the base plate, the depth of the buried pile integrally buried into a gravel sand or a soil layer of a bank is greater than a block thickness of the base plate, the circumferential side of the base plate is connected to splicing segments, separately, an upper seepage hole and a lower seepage hole are formed in the directions of the upper and lower splicing segments, separately, and after overlapping, the upper seepage hole is formed right below or obliquely below the lower seepage hole, and gaps are reserved among the corresponding splicing segments. The concrete block of the revetment of a light high strength structure is long in service life and convenient to maintain, can play a smooth flow guiding role, can form relatively high all-roundholding power, and reduces damage caused by wave energy centralization, settlement, expansion and contraction and the like effectively. During construction, it is convenient for a worker to stay, andthe concrete block is convenient to product, transport and fill, so that a revetment structure is protected more favorably.

Description

technical field [0001] The invention belongs to the field of water conservancy engineering, and in particular relates to a bank revetment concrete block. Background technique [0002] The revetment is mainly used to defend against the damage caused by waves and currents in the water area to the slope and land, and to ensure the safety of land personnel and infrastructure. At present, most commonly used revetment structures are formed by connecting concrete blocks, and are designed according to the hydrodynamic characteristics of coasts and river banks. [0003] In order to strengthen the embankment structure and prevent the erosion and loss of sand and soil caused by rapid current impact, surge, rain, etc., the design of revetment structure with better performance is essential. The existing revetment block ignores the integrated structural design that enhances the vertical grip between itself and the embankment sediment layer or soil layer and the mutual support between eac...

AI Technical Summary

Problems solved by technology

The existing revetment block ignores the integrated structural design that enhances the vertical grip between itself and the embankment sediment layer or soil layer and the mutual support between each revetment block, which is prone to collapse and washout of the revetment block, and The laying of traditional geotextiles is often used to solve the foundation settlement caused by the impact of water flow, and the embankment cannot be consolidated. The construction process is cumbersome and time-consuming, and the appearance of splicing gaps is also likely to cause the bank protection block to collapse and fall off due to sand loss.
