Gully land reclamation structure and method for loess plateau gully treatment and land reclamation
The invention discloses a gully land reclamation structure and method for loess plateau gully treatment and land reclamation. The gully land reclamation structure comprises original gully shallow soil, a filled loess foundation and a farmland. The original gully shallow soil, the filled loess foundation and the farmland are sequentially arranged on the original gully bed rock surface of the to-be-regulated gully land from bottom to top; the filled loess foundation comprises a bottom bearing layer, a middle transition layer and a top water filtering layer which are sequentially arranged from bottom to top, and the compaction degree of the bottom bearing layer, the compaction degree of the middle transition layer and the compaction degree of the top water filtering layer are gradually decreased. According to the invention, different filling soil layers achieve different functions by changing the compaction degree of the vertical filler of the filling project, so that the three functions of bearing weight, preventing and controlling collapsibility and filtering and draining water are achieved; the problem of filling soil of the loess plateau gully treatment and land reclamation can be effectively solved, safety and use of gully structures are guaranteed, and popularization and use are facilitated.
本发明公开了一种黄土高原治沟造地的沟道土地整治结构及方法，包括原始沟道浅层土壤、填方黄土地基及农田；原始沟道浅层土壤、填方黄土地基及农田由下至上依次布置待整治沟道土地的原始沟道基岩面上；填方黄土地基包括由下至上依次布置的底部承载层、中间过渡层及顶部滤水层，底部承载层、中间过渡层及顶部滤水层的压实度逐步递减；本发明通过改变填方工程竖向填料的压实度，使不同填方土层实现不同的功能，以具备承担重量、防控湿陷及滤水排水的三重作用；能有效解决黄土高原治沟造地沟道土壤的填土问题，保证沟道构筑物的安全与使用，便于推广使用。
