Wall body formed by modular latch locking type permeable blocks

The invention discloses a wall body formed by modular latch locking type permeable blocks. The wall body comprises a top block, a middle block, a bottom block, and concave pits and lugs arranged on the three parts, wherein when the three parts are stacked into a whole from top to bottom, the concave pits and the lugs are arranged in a matching and splicing way; inserting slots are formed in the opposite surfaces of the concave pits and the lugs. The invention provides the wall body formed by the three parts, and the wall body can be standardly manufactured, and is convenient to be transported and stored; the three parts are arranged through the concave pits and the lugs in a matching and splicing way, so that the structure is simple, and the wall body is convenient to be manufactured, and the splicing structure can be matched stably; gaps between the concave pits and the lugs form drainage structures, so that water can be drained lengthways and quickly; the inserting slots are arranged to have two selection purposes, namely when latches are not arranged on the inserting slots, the latches can be used as the drainage structures for improving the drainage capability, and when the latches are arranged on the inserting slots, the structure among the three parts can be stabilized, and the three parts are not easy to be swung or separated, so that the stability and the firmness of the whole wall body are improved.
