Construction and cyclic utilization method of reusable muck digestion field

According to the reusable muck absorption field construction and cyclic utilization method, the earth retaining dam is a gravity dam with the vertical completely-isolated construction joints, the dam blocks can be independent from one another through the construction joints, the forcible entry construction difficulty is reduced in the reuse stage, the cost-efficiency ratio of muck reuse is increased, and economic benefits are improved; according to the gravity dam, it can be guaranteed that after a certain dam block is broken, the adjacent dam blocks can still keep stable, and the safety of a reuse project is guaranteed. The pond slag filling body in the site has the characteristic of self-stabilization, the formation of separation grids can be ensured in a muck absorption stage, muck absorption blocks are reasonably divided, and the construction organization of site absorption work is facilitated; the reuse stage plays a role in isolation and protection, and the enclosure does not utilize the muck of the blo
