Abstract

The utility model discloses a breakwater protection block, which belongs to the technical field of port water conservancy engineering. It consists of a polygonal bottom plate and a polygonal water-dividing support column connected to a polygonal bottom plate; the polygonal water-dividing support column is provided with a central hole, and the end connected to the polygonal bottom plate is alternately provided with a groove communicating with the central hole; the polygonal bottom plate is a regular six In the shape of a side, there is a bite groove in the middle of the interval of each phase, and a protrusion matching and connecting with the bite groove is arranged in the middle of the other interval. The utility model is that waves and water flow divide water and collide with each other to dissipate energy between the face protection blocks and in the openings of the face protection blocks, which improves the wave dissipation function and reduces the climbing of waves on the revetment and slope type breakwater slope. And current velocity, can be used to protect and strengthen revetment and slope type breakwater face protection surface. The breakwater protection block of the utility model has a simple structure, is convenient for construction and repair, has low cost, effectively improves its comprehensive technical and economic performance, and has practical value.

Description

A breakwater protection block

technical field

The utility model relates to a wave-dissipating component of a slope breakwater embankment in natural water bodies such as rivers, lakes and seas, and more specifically relates to a slope-type breakwater protection surface block, which belongs to the technical field of water conservancy engineering.

Background technique

At present, the slope type breakwater is the oldest type, and it is also the most widely used type of breakwater in domestic and foreign seaport projects; it mainly uses natural block stones, concrete blocks and various artificial blocks as protective surfaces. This requires us to choose the appropriate face protection block according to the specific use environment. In order to meet the increasingly complex conditions and higher and higher requirements for engineering construction, the types of breakwaters are constantly being updated and developed. Research on face armor blocks with good stability, low reflection, low climbing height, reasonable reliability and practicability to ensure the use function of the breakwater and reduce the cost. Many special-shaped blocks have appeared, which have greatly improved the wave dissipation performance and stability of slope embankments, but there are many problems such as easy generation of dead water, poor wave dissipation performance, and high cost. To a lesser extent. For example, a kind of slope embankment protection commonly used in my country-concrete fence board, the stability of the fence board protection to the underwater support prism and the flatness of the cushion stones are relatively high, and it is generally suitable for higher wave heights. In the case of small, when the wave climbs higher, the protection effect on the breakwater is poor.

Contents of the invention

Technical problem: the purpose of this utility model is to solve the problems of poor wave dissipation performance and complicated construction of the existing slope-type breakwater protection block for the deficiencies and defects in the prior art, and to provide a new type of slope-type breakwater protection surface blocks.

Technical solution: In order to achieve the above purpose, the technical solution of the utility model to solve the above technical problems is: a breakwater face protection block is composed of a polygonal bottom plate 1 and a polygonal water diversion support column 2 connected with the polygonal bottom plate 1; The polygonal water diversion support column 2 is provided with a central hole 3, and one end connected to the polygonal bottom plate 1 is alternately provided with a groove 4 communicating with the central hole 3; the polygonal bottom plate 1 is a regular hexagon, separated by a middle There is a bite groove, and a protrusion matching and connecting with the bite groove is provided in the middle of the other interval; the polygonal water diversion support column 2 is equilateral to the multi-deformation bottom plate 1; the entire breakwater face protection block is made of plain concrete , Steel-concrete or reinforced concrete manufacturing.

Beneficial effects: the advantages and beneficial effects of a breakwater face protection block of the utility model are mainly as follows: first, when waves act on the face protection block, the waves and water flows between the face protection blocks and the opening of the face protection block Water separation and collision energy dissipation are carried out in the channel, which improves the wave dissipation function, reduces the climbing height and water flow velocity of waves on the revetment and slope type breakwater slope, and can be used to protect and strengthen the revetment and slope type breakwater surface protection surface; The second is that the face protection block has a simple structure, convenient construction, low cost, and the requirements for the flatness of the cushion block are not too high, easy to repair, economical and environmentally friendly, effectively improving its comprehensive technical and economic performance, and has practical value .
