The concrete blocks for retaining wall and revetments

摘要

The present invention is a vegetation raft block which is a raft block for plant cultivation of nature-friendly concrete that is constructed on the banks of rivers and shores or on road surfaces, and more specifically, the interconnection structure between the raft blocks (11, 15, 51, 55, 57) and the shape of the hole for plant cultivation (14, 46), by making the strong binding force only through the interlocking of the raft block to shorten the construction period, can be easily and economically installed, the construction of the river bank Prevents the outflow of soil and prevents the collapse of shelter or surface due to heavy rains, and eliminates the need for additional maintenance after construction, and increases the area of plant cultivation holes (14, 46) on the exposed surface after construction. Increasing the aesthetic performance of the construction surface, and allowing many plants to grow effectively, such as ease of construction, solidity of the construction body, environmental friendliness, aesthetics As having the anti-falling off function to contribute to the improvement of plant cultivation relates to a vegetation revetment block,;A trapezoidal plant cultivation hole (14, 24, 34) in which the bottom portion formed in the body of the revetment block becomes narrow so that the plant can grow natively;;A plant cultivation hole 46 formed in a gap with the language block which is connected at the time of assembly of the language block so that the plant can grow natively;;A drainage flow path 13 flowing in the construction surface as a valley between the body 20 and 30 of the bank block having the gravel shaped protrusions 12, 22 and 32 and the gravel shaped protrusions 12, 22 and 32;;A pair having fitting projections 11 and 51 and fitting grooves 15 and 55 respectively formed on four surfaces of the raft block to prevent the raft block from being separated from each other in the constructed state and to have a strong binding force. With fitting portion of;;It is characterized in that it comprises a coupling groove (57), such as a key groove formed by engaging the engaging projections (11, 51) and the fitting groove (15, 55) to each other.
