Embodiment Construction

[0021] Such as Figure 1-5 As shown, a method to eliminate post-construction settlement of subgrade high fill, bridge abutment, and backfill of culvert walls, before the soil foundation is handed over or at a certain stage of construction, according to the designed post-construction settlement, such as figure 1 According to the arrangement method of plum blossom piles as shown, the compacted piles are driven into the foundation or soil foundation, such as figure 2 ,image 3, Figure 4 As shown, the compaction piles are arranged longitudinally along the roadbed with small size and are arranged outwards with bridges and culverts and other structures and the steel flexible joints of the roadbed. The cross-section of the roadbed is arranged from the outside to the inside. The top surface of the compaction pile is oval, such as Figure 5 As shown, the shape of the pile body is wedge-shaped, the surface of the pile body is a threaded outer surface, and the pile body is solid. In ...

Abstract

The present invention discloses a method for eliminating settlement after the roadbed, bridge abutment and culvert wall back are backfilled, and is characterized by that according to the settlement after work, before the earth foundation is handed over or in some stage of construction the compaction piles can be driven into ground base or earth foundation. Said invention uses control of road surface deformation as core, and ensures that the roadbed and ground base do not settle after construction so as to ensure that the road is unimpeded and safe.

Description

technical field [0001] The present invention relates to a method for eliminating settlement after backfilling of high embankment, bridge abutment and culvert wall backfill, in particular to a method for eliminating settlement after backfilling of high embankment fill, bridge abutment and culvert wall backfill by piling compaction method Methods. Background technique [0002] Our country has a vast land, various topographic and geological conditions, and many mountainous areas, especially in the northwestern part of our country. With the implementation of my country's western development strategy, the transportation industry in the central and western regions has been greatly developed, especially the construction of high-grade highways will reach a new peak. Due to the high current technical indicators of high-grade highways, when they enter mountainous areas, high backfill earthworks behind high-fill subgrades, viaduct abutments, and retaining walls of small bridge culvert...
