Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, 2 and 3, the assembled ecological retaining wall of the present invention comprises a plurality of rectangular cylindrical open caisson 1 inserted into the soil near the river levee.
The lower part of the open caisson 1 is a soil insertion section, the bottom end of the open caisson is provided with an insertion hole 6, and an orifice 60 of the insertion hole is arranged to be an inclined plane and is in a blade shape, so that the capability of inserting the open caisson into the river bottom soil can be improved, and the binding force between the open caisson and the river bottom soil can be improved.
The open caisson 1 is provided with a fish nest cavity 2 for providing an oviposition and living area for aquatic animals. The fish nest cavity 2 is arranged on the left side and the right side of the open caisson 1 and the upstream face. The fish nest cavities 2 on the three sides are communicated by a communication hole 3. The fish nest cavity can provide long-term improvement for living and breeding of fish and other organisms, and the influence of engineering on a near-water bank ecological system is reduced.
The open caisson 1 is provided with a permeable hole 5 to ensure the nutrient exchange between the interior of the wall and the water body in the slope. And one end orifice of the water permeable hole 5 is arranged on the back surface of the open caisson, and the other end orifice can be arranged in the fish nest cavity.
The upper part of the open caisson 1 is high in thickness, and can replace a traditional retaining wall to play roles in maintaining stability of a shoreline, preventing erosion and scouring of water flow and the like. The open caisson upper portion forms increases connects platform 7, increases the top surface of connecting platform 7 and can further set up to basin shape 70, before no secondary construction adds the construction reinforced concrete layer, the basin forms the top and plants the groove, builds whole view ecological effect, has certain ecological benefit. When heightening construction, the bonding strength of the front and rear construction structures can be improved.
The open caisson can be transported to the site for use after being poured and maintained in advance. When the bank protection is built, a plurality of open caisson are uniformly arranged along the river bank, a cofferdam is not required to be built, and the lower end of the open caisson is directly embedded in soil by utilizing hoisting equipment. When the water bank planning is changed, particularly the thickness of a soil layer behind a slope is increased, the original revetment can not meet the requirement, and the requirement can be met by the revetment with higher height, a reinforced concrete layer 4 is constructed and added for the second time on the basis of the original open caisson, and the top thickness of the open caisson is increased, so that the purpose of meeting the near-term and long-term planning requirements is achieved.
It should be noted that the above describes exemplifying embodiments of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the present invention, and that there may be many variations and modifications without departing from the scope of the present invention, all of which fall within the scope of the claimed invention.
