Abstract

The invention discloses a pre-compacted reinforced soil block flexible supporting structure, wherein the intermediate course is a layered integral body formed by wrapping plural horizontal annular reinforced pre-compacted soil blocks (7) with vertical annular geogrids (8) at each layer and connecting by a nail, soil aggregate (13) is filled between the horizontal annular reinforced pre-compacted soil block (7) at the inner side and a side slope to form an inner side drainage layer (16), the vertical annular geogrids (8) at two layers are connected through a connection rod (17), the horizontal annular reinforced pre-compacted soil blocks (7) at each layer are connected with each other via a nail (9), and the pre-compacted horizontal annular wrapped reinforced soil block in a bottom water permeable layer (3) and a slope top water permeable layer (1) is formed by filling soil aggregate (13) in a horizontal annular geogrid (19) and compacting on field. The invention is suitable for rapid repair of water damaged or collapsing road slope of expansive soil, red clay and red sandstone, and has low application cost, no road occupation in construction, convenient process and fast construction speed.

Description

technical field [0001] The invention relates to a road slope protection, which is a flexible masonry structure of pre-compacted reinforced soil block. Background technique [0002] Existing patent publication (announcement) No.: 201891130U The patent of prefabricated block flexible retaining wall structure discloses a retaining structure. It is composed of vertical connecting bars and transverse geotechnical anchor rods of the building layer. The application cost of this structure is high, and it is not suitable for geological conditions such as expansive soil and red clay; a kind of flexible reinforced retaining structure and its construction method (public (announcement) number: CN100464034) The flexible retaining structure provided by this invention has the following Structural features: the bottom of the retaining structure is a permeable base layer, and there is a permeable layer between the retaining structure and the excavation surface. Reinforcements are laid in th...
