Reinforced fly ash soil retaining wall and construction method

Abstract

The invention discloses a reinforced fly ash soil retaining wall and a construction method. The reinforced fly ash soil retaining wall is composed of three parts including padding, reinforcing ribs arranged in the padding and a wall face plate. The method includes the steps that firstly, a retaining wall base groove is excavated on a to-be-constructed ground, foundation construction is conducted, the wall face plate is built on a foundation through building blocks, a settlement joint and an expansion joint are arranged when the wall face plate is built, and geogrids are built between the building blocks of the wall face plate at certain intervals; then, an EPS foam plastic plate is stuck to the wall face plate and is polished; and finally, the saponification residual slag-fly ash-soil light padding is used for backfilling, the performance of the padding should meet the design requirement in the compaction process during filling, manual spreading is adopted close to the EPS foam plastic plate, the rest of the parts are spread, ground and compacted through a machine till each layer of geogrid rib materials are spread and the padding is spread and compacted, and construction of the reinforced fly ash soil retaining wall is completed. The reinforced fly ash soil retaining wall has good performance that the structure is simple, construction is convenient, durability is good, and ageing resistance is achieved.

Description

technical field [0001] The invention relates to a retaining wall structure in geotechnical engineering, in particular to a reinforced fly ash soil retaining wall and a construction method. Background technique [0002] Reinforced soil retaining wall is a retaining structure built using reinforced soil technology. Reinforced soil is a kind of composite soil with tension belts added to the soil. It uses the friction between the tension bars and the soil to improve the soil The deformation conditions of the body and the engineering performance of the soil are improved, so as to achieve the purpose of stabilizing the soil. At present, there are some deficiencies in the engineering application of reinforced soil retaining walls. For example, the filling part needs to consume a large amount of soil resources, the interface friction strength between the reinforcement and the filling is not high, and the connection between the face plate and the reinforced soil is weak.

AI Technical Summary

Problems solved by technology

At present, there are some deficiencies in the engineering application of reinforced soil retaining walls. For example, the filling part needs to consume a large amount of soil resources, the interface friction strength between the reinforcement and the filling is not high, and the connection between the face plate and the reinforced soil is weak. Popularization and Application of Reinforced Soil Retaining Wall

At present, the better reinforcement measures for reinforced soil retaining walls mainly include increasing the compaction degree of the fill, increasing the length and strength of the reinforcement, etc., but the construction period of these measures is long and the cost is high
