Description

Fish nest type hinge row and underwater bank protection structure adopting same

Technical Field

The utility model relates to a bank protection structure, especially an underwater bank protection structure.

Background

For a restrictive channel with a narrow river width, besides the influence of water flow conditions, ship traveling waves are also strong hydrodynamic factors and are main dynamic factors for bank slope damage. In order to effectively prevent unstable damage of a bank slope in a wave impact area under the influence of ship traveling waves, hard protective structures such as cast-in-place concrete panels and the like are often adopted for the restrictive channel below the normal water level. The hard protection structure is beneficial to resisting scouring and washing of hydrodynamic force such as ship travelling waves, protects the structural stability of the bank slope protection engineering slope, and prevents water and soil loss. However, the following problems also exist: firstly, the relation between the water body and the soil is completely cut, and the resource function and the ecological function of the river are destroyed. Secondly, the utility model occupies the inhabitation space of the organisms such as fish, shrimp and the like, and destroys the living environment of the aquatic organisms. Thirdly, the surface of the concrete panel forms a smooth surface with extremely small resistance under water, which is not beneficial to survival of people falling into water due to foot loss.

The ecological river protection method is green, safe and ecological, is the development direction of future channel construction, is suitable for underwater ecological bank protection structures with the fish nest function below the normal water level of a restrictive channel, and is the actual requirement of ecological river management and ecological channel construction.

The upper and lower sides of the hinge row are provided with groove-shaped structures which are recessed from two ends to the middle step.

The upper periphery of the hinge row is provided with a slope.

The utility model discloses a solve another technical scheme that technical problem that exists among the known art adopted is: the underwater revetment structure comprises a plurality of blocks fully paved on a slope surface, the fish nest type hinge rows are arranged in rows from top to bottom, the two adjacent rows are arranged on the left side and the right side, the fish nest type hinge rows are arranged in a staggered mode, two adjacent meshing teeth of the fish nest type hinge rows are mutually meshed, and each meshing tooth is internally meshed with two parallel meshing teeth from top to bottom.

Description

And groove-shaped structures which are recessed from two ends to the middle step are arranged on the upper side and the lower side of the fish nest type hinge rows, and a strip seam which extends along the water flow direction and is closed at two ends is formed between two fish nest type hinge rows which are adjacent from top to bottom.

The utility model has the advantages and positive effects that: the underwater bank protection structure forms self-locking connection through staggered occlusion among the hinge rows along the water flow direction, and the structural stability is good; the fish nest holes which are arranged on the hinge rows and are communicated up and down increase the inhabitation space of aquatic animals and the growth space of plant roots. In addition, the fish nest hole can also provide the tongs for falling water personnel to seek survival to the climbing of bank direction. The utility model discloses specially adapted restrictive channel.

Detailed Description

For further understanding of the contents, features and functions of the present invention, the following embodiments will be exemplified in conjunction with the accompanying drawings as follows:

referring to fig. 1 to 4, a fish nest type hinge row 1 is a block body with an i-shaped cross section, four corners are respectively provided with an engaging tooth 1-1, the left side and the right side are respectively provided with an engaging tooth groove 1-2, the middle part is provided with a fish nest hole 1-3 which is through up and down, and each engaging tooth groove 1-2 can engage two engaging teeth 1-1 which are arranged up and down in parallel.

In the embodiment, for the convenience of construction and installation, the upper side and the lower side of the hinge row are provided with groove-shaped structures which are recessed from two ends to a middle step. For convenience in manufacture, the fish nest holes 1-3 are strip-shaped holes extending along the up-down direction of the slope; the periphery of the upper part of the hinge row is provided with an inclination, so that the demoulding is convenient.

Referring to fig. 4 to 5, an underwater bank protection structure using the fish nest type hinge row includes a plurality of fish nest type hinge rows 1 fully paved on a slope, the fish nest type hinge rows 1 are arranged in a row from top to bottom, two adjacent rows of the fish nest type hinge rows 1 are arranged in a staggered manner, two adjacent engaging teeth 1-1 of the two fish nest type hinge rows 1 arranged in a staggered manner are engaged with each other, and two engaging teeth 1-1 which are parallel from top to bottom are engaged in each engaging tooth groove 1-2.

Because the upper side and the lower side of the fish nest type hinge row 1 are provided with groove-shaped structures recessed from two ends to the middle step, strip seams 2 which extend along the water flow direction and are sealed at two ends are formed between the two fish nest type hinge rows 1 which are adjacent from top to bottom, the hand grip can be provided for people falling into water to climb in the shore direction, and meanwhile, the connection between a water body and soil can be enhanced.

Above-mentioned bank protection structure under water passes through crisscross interlock formation auto-lock between the fish nest hinge row 1 along the rivers direction and is connected, has guaranteed the stability of bank protection structure. The elongated fish nest holes 1-3 have the following functions: firstly, the whole weight of the structure is reduced, and the construction is convenient; secondly, a habitat space is provided for the aquatic animals; thirdly, more ploughing and planting soil can be filled, so that more growing space is provided for the root system of the plant; fourthly, the structure gripper can be provided for the people falling into the water to seek survival.

When the underwater bank protection structure is constructed, firstly, the bank slope foundation 3 is cut to be smooth to form a slope surface 4, and then the fish nest type hinge row 1 is laid on the slope surface 4.
