Embodiment

[0036] Such as Figure 1 to Figure 5 , a method for constructing a mechanically stable retaining wall of a highly filled embankment, comprising the following steps:

[0037] Step 1. Structural design of retaining wall system for mechanical stability of subgrade

[0038] Use Aketchup software to establish the calculation model of the retaining wall structure, design the structural reinforcement of the retaining wall based on this, and carry out the foundation design of the retaining wall according to the bearing capacity of the foundation and the friction angle of the backfill layer, and divide the wall into blocks The design of typesetting and outer texture is convenient for on-site prefabrication;

[0039] Step 2. Wall panel 2 prefabricated on site

[0040] Select a suitable site to facilitate the production and storage of prefabricated components of the retaining wall; customize the special supporting formwork according to the pattern pattern on the outer side of the retai...

Abstract

The invention discloses a construction method of a high-fill roadbed mechanical stability retaining wall, and belongs to the technical field of retaining wall construction processes. The constructionmethod comprises the steps: 1, structural design of the retaining wall is conducted; 2, wallboard mounting and roadbed backfilling are conducted; and 3, A1, footing step mounting, A2, first-layer wallboard mounting, A3, perforated water seepage pipe mounting, A4, ground elevation face selecting, and A5, backfilling compaction are included. In the construction process, construction safety is improved by adopting a corresponding monitoring measurement technology, stability of a roadbed mechanical stability retaining wall system in the processes of wall body structure mounting and roadbed earthwork backfilling compaction is ensured, wall body collapse and roadbed slumping are avoided, the construction quality is improved while the construction efficiency is improved, and the economic benefitsare brought to enterprises and society.

Description

technical field [0001] The invention belongs to the technical field of retaining wall construction technology, and in particular relates to a construction method of a high-fill subgrade mechanically stable retaining wall. Background technique [0002] With the development of municipal construction and road traffic, if a high-fill subgrade filled with slopes is used in the transportation hub area, more land will be occupied, which is not conducive to the traffic flow control of the transportation hub. As a prefabricated and assembled force-bearing structure, the retaining wall system for subgrade mechanical stability plays an important role on municipal high-fill subgrade roads, and can effectively realize traffic diversion and reduce land occupation of overpass bridges. However, there are no mature technologies and similar engineering cases for reference. During the construction process, how to carry out modular fabrication and installation of slabs, how to carry out backfi...
