Detailed Description

The present invention will be described in further detail with reference to the following drawings and embodiments:

as shown in fig. 1, the utility model discloses a groove 3 and a plurality of fish nest cavity 4 are planted to wall body 1, base 2, one or more view, and they are mainly pour by no sand concrete and are accomplished, have high water permeability and gas permeability, can guarantee the material exchange between the soil body and the river water, have avoided adopting the ecological destruction that hard concrete brought. The sand-free concrete structure with good water permeability increases the water permeable path of the soil body behind the wall, so that the allowable pressure of the wall back is increased. Meanwhile, the cost of the sand-free concrete is lower than that of common concrete, and the sand-free concrete has certain economical efficiency. Compared with other concrete, the sand-free concrete can adopt a colorful formula, so that the retaining wall can better meet the landscape design requirement.

The wall body 1 and the base 2 are poured into a whole, the water permeability is excellent, and the water body in front of the wall and the soil body behind the wall can exchange materials. The landscape planting groove 3 and the fish nest cavity 4 are arranged on the upstream surface of the wall body 1, and the landscape planting groove 3 is arranged above the fish nest cavity 4. The landscape planting grooves 3 and the fish nest cavities 4 are separately manufactured structures, and can be installed on the upstream face of the wall body by formwork erection pouring after the wall body 1 and the base 2 are constructed, or can be installed on the upstream face of the wall body by corresponding supporting structures and anchoring structures by adopting prefabricated bodies.

And homogeneous backfill soil is paved in the landscape planting tank 3 to be used as a plant growth substrate. The height of the landscape planting tank 3 can be lower than the water level, higher than the water level or near the water level as required. The upstream surface of wall body 1 can set up many places view and plant groove 3, and the view that is located different positions plants groove 3 can have different heights, can plant different plants, satisfies the view planning requirement, and simultaneously, view plants groove 3 can set up different shapes, increases the pleasing to the eye degree of bank protection. The fish nest cavity 4 is provided with an opening 40 and an internal cavity communicated with the opening, and the fish nest cavities 42 and 43 are positioned at two sides and are closed at the sides; a fish nest cavity 42 at the top, the top of which is closed; the bottom of the fish nest cavity 41 is closed, and the fish nest cavities are communicated with each other all around, so that an integral space for living and breeding of fish and other organisms is provided.

The fish nest chamber 4 is a concrete member of generally cubic shape for ease of manufacture and installation, and the communication holes therebetween may be formed by chiseling through the walls of the chamber prior to installation. As shown in the figure, the plurality of fish nest cavities 4 can be arranged in layers and are arranged in multiple layers, the fish nest cavities 4 on the same layer have the same outline and can be made of the same components, the fish nest cavities on the upper layer and the lower layer are connected by the anti-skid grooves 51 and the anti-skid tenons 52, and the fish nest cavities on the same layer are fixed by the anchor rods 6, so as to further reinforce the overall installation structure of the fish nest cavities 4.
