Problems solved by technology

Due to the narrow construction space, the quality of compaction, excavation steps, and retaining wall drainage and filter layer cannot be guaranteed. In the context of rising material prices, general fillers are often used to backfill the "V" groove during construction. The groove is often the area for water storage and rainwater runoff, which further reduces the quality of the "V"-shaped backfill area. Under unfavorable working conditions, longitudinal cracks often appear in the subgrade, which affects the safety of the subgrade and vehicles.

Abstract

The invention discloses a retaining wall system capable of reducing the construction influence and a construction method for the retaining wall system, and relates to the field of engineering construction. The retaining wall system comprises an air pressure energy dissipation layer, an air pressure partition plate and a ground line, a retaining wall is arranged above the left side of the ground line, the air pressure energy dissipation layer is arranged on the right side of the retaining wall, and a sand bag layer is arranged on the right side of the air pressure energy dissipation layer; andan inverted filter geotextile is arranged on the right side of the sand bag layer, and embankment filling soil is arranged on the right side of the inverted filter geotextile. According to the retaining wall system capable of reducing the construction influence, through cooperation of the air pressure energy dissipation layer and an energy dissipation device, ramming force generated during embankment filling construction is effectively absorbed, and the situation that the retaining wall is damaged due to vibration generated by the ramming force during construction is avoided.

Description

Technical field: [0001] The invention relates to the field of engineering construction, in particular to a retaining wall system and a construction method for reducing construction impact. Background technique: [0002] The retaining wall is a structure to prevent the deformation and instability of filling or soil. In terms of limited land use and improving the stability of embankments, retaining walls are widely used in industries such as highways, municipalities, and waterways. On the premise that the construction does not affect the safety of the retaining wall structure, in order to ensure the compactness of the backfill of the abutment, the "Technical Specifications for Construction of Highway Subgrade" requires that the filler be made of water-permeable materials, lightweight materials, and inorganic binder stabilized materials. Use small-scale tamping equipment for compaction within 1.0m of the back of the wall, and the layered compaction thickness should not be great...
