Waterside road broadened embankment structure and construction method thereof

Abstract

The invention relates to a waterside road broadened embankment structure, which is characterized in that the waterside side of a new embankment is provided with a waterproof maintenance pile, and the outer side of the maintenance pile is provided with a dumping stone weights body; the lower part of the new embankment is a solidified soil layer, the upper part of the new embankment is a lightweight filler layer, and the contact part of the solidified soil layer and the lightweight filler layer is provided with a horizontal reinforced body and a vertical reinforced body; a grouting strengthened body is arranged in an original embankment, and the front end of the grouting strengthened body is a reinforced connecting section; and the side slopes on the top surface and outer side of the new embankment and the two sides of the maintenance pile are respectively provided with a waterproof later, and the bottom of the dumping stone weights body is provided with an impervious blanket. According to the invention, the connection strength and integrity of the new and original embankments can be enhanced, an outside water body is prevented from permeating in the embankments from multiple beddings, and the anti-uplift performance of the embankment can be improved, therefore, the embankment structure has good technical and economic benefits. The invention also provides a construction method of the broadened embankment structure.

Description

technical field [0001] The invention relates to a road embankment widening structure, in particular to a waterside road widening embankment structure and a construction method, which can enhance the strength and integrity of a new original embankment, prevent the infiltration of external water bodies, and improve the anti-floating stability of the embankment. It belongs to the field of highway engineering and is suitable for old road reconstruction and expansion projects, especially for single-side or double-side embankment widening projects on Linshui Highway. Background technique [0002] In recent years, with the rapid development of my country's economy, the traffic volume of highways has been increasing year by year, and the traffic volume of some highways is close to saturated traffic volume. In this regard, in order to meet the growing traffic demand and social development needs, road reconstruction and expansion projects are becoming more and more important. many. Al...

AI Technical Summary

Problems solved by technology

However, the existing measures rarely involve the improvement of the bearing capacity of the old embankment and the control of the re-settlement (deformation) of the old embankment due to the increase of the oblique load; The possible floating problem and the overall anti-seepage problem are often not considered, and there are certain engineering hidden dangers
