Piled retaining wall embankment

Abstract

The invention provides a piled retaining wall embankment. The piled retaining wall embankment is characterized by comprising a bearing part, a connecting layer, a geogrid layer, a cushion layer, an embankment layer and retaining walls; the bearing part includes multiple groups of vertical bearing piles; the connecting layer includes multiple groups of pile caps and multiple groups of connecting beams, the pile caps correspond to the vertical bearing piles respectively and are fixed onto tops of the vertical bearing piles, the connecting beams are connected between the two adjacent pile caps, and the pile caps are connected integrally through the connecting beams; the geogrid layer is paved on the connecting layer; the cushion layer is paved on the geogrid layer; the embankment layer is paved on the cushion layer; the retaining walls are fixedly arranged on the connecting layer and are located on side area of the construction side. By the arrangement, stress condition of embankment soilcan be improved effectively, the soil is locked solidly to well constraint horizontal stress, vertical bearing capability of side piles is fully utilized, resistance to differential deformation is improved, and new construction or broadening of a new road can be realized in the case of using only the original road red line space or small amount of land acquisition.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to a pile-supported retaining wall embankment, which is suitable for single-side or double-side widening of soft soil foundation roads, new connection sections or ramp embankment projects. Background technique [0002] In recent years, with the rapid development of the national economy, the construction of expressways in my country is very rapid, and a considerable part of new embankments, bridge embankment joints and ramp projects need to be built on soft soil foundations. However, among the expressways that have been built and used, due to the restriction of the socio-economic level, technical level and construction ideas at the time of construction, a considerable part can no longer meet the requirements of traffic growth and social development. For highways on soft soil foundations, the pile-supported embankment has both a horizontal reinforcement (cushion)...

AI Technical Summary

Problems solved by technology

However, with the high development of county economy in coastal areas, land acquisition is becoming more and more difficult, and the cost of expropriation is increasing year by year

[0003] The use of traditional pile-supported embankments still exists: insufficient lateral restraint of the reinforced body, poor resistance to differential deformation; waste of vertical bearing capacity of side piles; and waste of land resources due to large footprint
