Retaining wall structure and construction method thereof

Abstract

The invention discloses a retaining wall structure and a construction method thereof. The retaining wall structure comprises a retaining wall foundation and a wall body; the wall body comprises a wallface, a wall back and a wall top; and the retaining wall foundation comprises a wall heel located on one side of the wall back and a wall toe located on one side of the wall face. The retaining wallstructure is characterized in that a soil body located on one side of the wall back comprises a compact soil layer located on the upper portion of the wall heel and a raw soil layer located on the side, away from the wall back, of the compact soil layer; a hydrophobic layer is arranged between the compact soil layer and the wall back; water drainage holes are formed in the wall body and communicate with the hydrophobic layer; a drainage ditch is arranged on one side of the wall face; the raw soil layer comprises a plurality of vertically distributed water collection holes; the water collectionholes are full of rubbles; and the hydrophobic layer is provided with water guide pipes communicating with the water collection holes. The retaining wall structure has the high water drainage capacity, is beneficial for solving the problems that the hydrostatic pressure and expansion pressure on the side of the wall back of the retaining wall are too large due to rainstorms, and is high in structural stability and safety.

Description

technical field [0001] The invention relates to the technical field of road construction, and more specifically relates to a retaining wall structure and a construction method thereof. Background technique [0002] The retaining wall is a supporting structure that supports the lateral earth pressure, prevents the slope from collapsing, and ensures the stability of the roadbed. It is an important part of the road. stability has a crucial impact. [0003] The drainage performance of the retaining wall largely affects the structural stability of the retaining wall. Especially for the period of heavy rainstorms in summer, a large amount of rainwater seeps into the soil on the back side of the wall, forming strong hydrostatic pressure and expansion pressure, while the soil layer near the back of the wall has been compacted, and its water permeability is weaker, making the infiltration into the soil It is difficult for rainwater to be quickly discharged through the drainage hole...
