AI Technical Summary

Technical Problem

In the existing technology, the drainage outlets of comprehensive land improvement in farmland and the surrounding soil walls are easily damaged by erosion, and the depth-to-width ratio of the drainage outlets is limited and difficult to expand, which affects the stability and ecology of the soil drainage structure.

Method used

An earthen drainage structure with grooves and slope protection bag assemblies on the back sill is adopted, combined with the design of anchor rod assemblies and slope protection bag assemblies. By setting notches and slope protection bag assemblies on the top of the back sill, fixed with anchor rod assemblies, and combining vegetation outer bags and woven inner bags to fill with soil and seed mixture, ecological protection is formed, and spoiler columns are set in the grooves to guide water flow and prevent lateral expansion.

Benefits of technology

It effectively prevents the lateral and vertical expansion of the drainage outlet, improves the stability and service life of the soil drainage structure, enhances the ecological performance, and can increase the depth-to-width ratio of the drainage outlet by five times, thereby reducing soil erosion.

Abstract

The soil drainage structure comprises a back ridge, a groove is formed in the slope surface of the back ridge, a notch is formed in the portion, at the top of the back ridge, of the field ridge, slope protection bag assemblies are stacked on the surface of the groove, anchor rod assemblies are inserted into the slope protection bag assemblies in a penetrating mode, and the anchor rod assemblies are inserted into the back ridge in a penetrating mode. The gaps between the slope protection bag assemblies and the grooves are filled with soil, the two slope protection bag assemblies at the top of the back ridge are arranged on the side of the notch, and a channel formed between the two slope protection bag assemblies at the top of the back ridge is matched with the notch. The soil texture drainage structure can effectively prevent the drainage port from continuously expanding transversely and longitudinally, the drainage port and the surrounding soil wall cannot be scoured and damaged even in the use process of a reconstructed paddy field, and the service life of the soil texture drainage structure is remarkably prolonged.
