A widened embankment structure and construction method of high retaining wall filling section facing water suspension wall

Abstract

The invention relates to a widened embankment structure with a beside-water cliff high retaining wall fill section. The widened embankment structure is mainly composed of an original pavement structure, a transverse connecting reinforcement cage, grouted stiffeners, a new widened part pavement structure, a diagonal brace, a mortar rubble slope, a reinforced concrete continuous slab and a pre-stressed pipe pile, wherein the reinforced concrete continuous slab and the diagonal brace are arranged on the top of the pre-stressed pipe pile; one end of the diagonal brace is connected with the top of the pre-stressed pipe pile, while the other end of the diagonal brace is connected with a panel of an existing cantilever retaining wall; the grouted stiffeners are arranged on the base plate of the existing cantilever retaining wall and the bottom of the reinforced concrete continuous slab; the transverse connecting reinforcement cage is arranged between the panel of the existing cantilever retaining wall and an new widened embankment; a waterproof layer is paved on the upper parts of the reinforced concrete continuous slab and the grouted stiffeners, and a light embankment and the new widened part pavement structure are orderly cast on the waterproof layer; a slope protecting waterproof layer and the mortar rubble slope are arranged outside the slope of the new widened part pavement structure. The widened embankment structure with the beside-water cliff high retaining wall fill section is used for effectively solving the problem that the widening construction cannot be implemented as the existing cantilever retaining wall cannot be removed.

Description

technical field [0001] The invention relates to a widened embankment structure, in particular to a widened embankment structure and a construction method of a high retaining wall filling section facing a water suspension wall. The utility model belongs to the field of highway engineering, and is suitable for reconstruction and expansion projects of old roads, especially for embankment widening projects of high retaining walls near water. Background technique [0002] In recent years, with the rapid development of our country's economy, the traffic volume of roads has been increasing year by year. Due to the underestimation of the rapid growth of traffic in the early construction of roads, some roads with large operating volumes have shown a situation of saturated traffic volume, which has seriously affected transportation. influences. In order to meet the increasing traffic and social development requirements, it is inevitable to widen the existing roads. [0003] In view ...

AI Technical Summary

Problems solved by technology

[0006] To sum up, although there are some methods to deal with the abnormal settlement of soft soil subgrade in subgrade engineering, and the various treatment measures and methods have achieved good reinforcement effects under suitable engineering conditions, most of the construction procedures are complicated and cumbersome, and some road sections There will still be problems with subsidence abnormalities in the later stage
