Novel pile-plate type ecological retaining wall construction method

Abstract

The invention relates to a novel pile-plate type ecological retaining wall construction method. The novel pile-plate type ecological retaining wall construction method is characterized in that a novelpile-plate type ecological retaining wall is composed of anti-slide piles, retaining boards, bent steel bars, L-shaped fixed blocks, fixed blocks and vegetations. The construction includes the stepsthat soil excavation is carried out; the anti-slide piles are constructed, and connecting ribs are embedded on the side faces of the anti-slide piles; backfilling of backfill is carried out until thedesigned ground elevation is reached; the L-shaped fixed blocks and the fixed blocks are manufactured, and the L-shaped fixed blocks and the fixed blocks are fixed to the anti-slide piles; the retaining boards are manufactured, each retaining board is composed of a vertical part and a bent part, the retaining boards are installed layer by layer, filling of the backfill is carried out instantly after each retaining board is installed until the top elevation of the retaining board is reached, and planting areas are formed between the bent parts and the vertical parts of the upper and lower two adjacent retaining boards; and afforesting construction is carried out in the planting areas. A novel pile-plate type ecological retaining wall obtained by the construction method is reliable in structure and convenient and efficient in construction, completely solves the problem of drainage after wall retaining, is natural and beautiful and is in harmony with the environment.

Description

technical field [0001] The invention relates to the technical field of ecological retaining wall construction, in particular to a construction method of a novel pile-slab type ecological retaining wall, which is suitable for construction of road shoulder pile-slab walls, embankment pile-slab walls, road cutting pile-slab walls, and the like. Background technique [0002] As a light retaining structure, the pile-slab retaining wall is a commonly used reinforcement form for railway, highway, municipal and other engineering slopes. It is especially widely used in railway and highway engineering. Restricted conditions require a good effect on slope land. The commonly used anti-slide pile-slab wall is in the form of hanging slabs behind the piles, and the retaining board is placed on the back of the pile. Because the hanging slabs are simple, designers can easily accept it. [0003] However, the traditional design method of pile-slab walls will inevitably lead to the displacemen...

Problems solved by technology

[0003] However, the traditional design method of pile-slab walls will inevitably lead to the displacement of the anti-slide piles, the increase of the length and cross-sectional area of ​​the anti-slide piles, and the increase of the engineering volume.

After the traditional pile-slab wall construction is completed, the wall-soil contact layer needs to be provided with an anti-filter layer to prevent groundwater from seeping freely from between the retaining panels behind the pile-slab wall, and the surface of the pile-slab wall cannot be integrated with the surrounding ecology
