A soil retaining structure for the approach section of the elevated road ramp

Abstract

The invention discloses an elevated road ramp approach section retaining structure. The elevated road ramp approach section retaining structure comprises retaining walls on both sides, and the inner sides of the two side retaining walls are provided with wall heel slabs. The elevated road ramp approach section retaining structure is characterized by being in a U shape, and the wall heel slabs on both sides are connected to form an integrated floor plate. The elevated road ramp approach section retaining structure has the advantages of reducing the excavation surface during construction of retaining wall structures and the damage degree of roadbed surfaces of old roads; foundations are connected into a whole and bear stress together, so that high structural antidumping performance and good structure integrity can be obtained, and a more reasonable structural stress system can be achieved; when the width of ramps is small and the retaining walls are high, concrete and reinforcing steel bars can be saved.

Description

technical field [0001] The invention relates to the technical field of urban elevated road design, in particular to a soil retaining structure used for the ramp approach section of the elevated road. Background technique [0002] With the development of the city, the demand for fast and convenient connection of urban traffic has put forward higher requirements for the urban backbone road network, and the long-distance continuous flow traffic mode has undoubtedly become the best behavior of urban traffic. Therefore, major cities have gradually planned, remodeled and built express road network systems. Elevated roads have gradually become a main laying type of urban expressway network skeleton system. The elevated ramp is a basic way of connecting the elevated road and the surface road. [0003] Generally, the elevated ramp is located between the ground motor vehicle lane and the outer roadway (mixed traffic of motor vehicles and non-motor vehicles), so the protective struct...

Problems solved by technology

[0004] However, when the expressway is a rapid reconstruction of the existing road, the existing road is in good condition, and there are abundant underground pipelines, the toe part of the ramp retaining wall invades the existing road more, which is very destructive to the existing road. At this time, the conventional ramp The structural form of the retaining wall is not suitable, and a row-like ramp retaining wall structure is required
