Ladder-shaped ecological protection slope and construction method thereof

Abstract

The invention discloses a ladder-shaped ecological protection slope. The ladder-shaped ecological protection slope comprises a grouted rubble short wall, concrete inclined surface bottomless round barrels, bolts, geotechnical cloth, vegetation growing bags and dredging materials, the concrete inclined surface bottomless round barrels tightly abut against the grouted rubber short wall, the inclinedsurfaces face downwards, the concrete inclined surface bottomless round barrels are installed on a side slope with the geotechnical cloth fully laid, the lowest sides, with positioning grooves, of the round barrels are placed at the uppermost part, the highest sides of the round barrels are placed at the bottommost part, so that the top surfaces of the round barrels are basically horizontal, thena ladder shape is formed, the round barrels are fully laid at the whole side slope, the round barrels which are adjacent to each other up and down are positioned through the positioning grooves, theround barrels which are adjacent to each other left and right are connected by making the bolts pass through anchoring holes, the dredging materials fill the round barrels in a layered mode, coarse-grained soil is placed on the lower layers, fine-grained soil is placed in the middle layers, the vegetation growing bags filled with the fine-grained soil is placed on the upper layers, the bag surfaces with seeds are upward, moreover, the bag surfaces are basically flush with the tops of the round barrels, a space formed among the round barrels in a surrounding mode is filled with the fine-grainedsoil, and the surfaces of soil bodies are basically flush with the tops of the round barrels. The invention further discloses a construction method of the ladder-shaped ecological protection slope. The river channel dredging materials are utilized, so that the effects of being ecological and environment-friendly are achieved, and safe water loving of people is facilitated.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a stepped ecological slope protection and a construction method thereof. Background technique [0002] In the treatment of small and medium rivers, dredging is an essential engineering measure. When the content of pebbles and boulders in the upstream river is large, it is often considered to use these larger particles to make gabion mats or gabion retaining walls for slope protection and bank protection. However, for the dredging soil materials mainly composed of sand and clay in the middle and lower reaches, they are often transported to the spoil yard, which requires both land acquisition and transportation, which is time-consuming and laborious. A ladder-shaped ecological slope protection has been invented, which can make full use of dredging materials for river channels, and can also facilitate the safety and hydrophilicity of the public. It has the cha...
