Construction method of chain-lock ecological block retaining wall

Abstract

The invention discloses a construction method for a chain-lock type ecological block retaining wall. 1. Excavate on the side slope according to the designed excavation line, and stake out the hole positions of the anchor rods to be anchored on the excavation surface; 2. 3. Pouring the foundation of the retaining wall; 4. Place the first layer of chain blocks on the foundation of the retaining wall. The distance between adjacent chain blocks is equal to the width of a block. The holes on the slope of the chain block are aligned with the axis of the anchor rod. Place the first layer of blocks between the adjacent chain blocks to form the first layer of retaining wall; 5. Backfill the first layer of graded gravel behind the first layer of retaining wall, and then cover the channel of the first layer of blocks Fill the planting soil with grass seeds or flower seeds to form the first layer of chain-lock ecological retaining wall; 6. Repeat steps 4 and 5 on the first layer of chain-lock ecological retaining wall to form the second layer of chain lock 7. Repeat steps 4 to 6 until the construction of the entire chain-lock ecological retaining wall is completed. The invention is not limited by the excavation space and has strong adaptability to geological conditions.

Description

technical field [0001] The invention relates to a slope protection retaining wall, in particular to a construction method for a chain-lock type ecological block retaining wall. Background technique [0002] There are many forms of retaining walls for slope protection, such as gravity retaining walls, buttress retaining walls and cantilever retaining walls. This kind of retaining wall has a stiff appearance and lacks vitality and aesthetic feeling. In recent years, a self-embedded ecological block retaining wall has appeared, which has solved the problem of greening the surface and greatly improved the ecological function of the retaining wall. However, neither the traditional retaining wall nor the self-embedded ecological block retaining wall can solve the problem of limited excavation space. This is because when constructing the retaining wall, the soil behind the wall must be excavated first, and then backfilled in layers. If the excavation space is limited, the retaini...

However, neither the traditional retaining wall nor the self-embedded ecological block retaining wall can solve the problem of limited excavation space

This is because when constructing the retaining wall, the soil behind the wall must be excavated first, and then backfilled in layers. If the excavation space is limited, the retaining wall cannot be constructed; if anchors and soil nails are used for support, it is difficult to take into account the ecological landscape Function
