Urban road reconstruction method and structure jointly built with anti-flood wall and rear berm

Abstract

The invention discloses a reconstruction method for an urban road jointly built with a flood wall and a rear berm and a road structure. Filling soil of the rear berm of a local road section is excavated, and after the filling soil of the rear berm is excavated, a vertical wall of the flood wall and a thick heel slab are reinforced; then, cement-soil mixing piles are arranged on the outer sides of the wall heels; a road surface is newly built on the anti-flood wall heel slab reinforcing part and the cement-soil mixing piles; according to the method, the Binjiang road is widened, the width requirement for reconstruction and improvement of the urban Binjiang road is met, and the complete function and quality of the Binjiang road are guaranteed compared with local non-motorized vehicle lane canceling or sidewalk width compressing.

Description

technical field [0001] The invention relates to the field of urban riverside road reconstruction engineering, in particular to a method for urban road reconstruction and a road structure jointly built with a flood control wall and a back abutment. Background technique [0002] The high-quality development of my country's economy and society, the continuous growth of urban car ownership and the increasing living standards of the people have further put forward higher requirements for the number of motor vehicle lanes and the width of the slow traffic system on urban roads; due to urban development and planning adjustments, The functional orientation of some riverside roads has changed, the road grade has been improved, and the width of the planned road has increased; while urban riverside roads are often restricted by dikes or flood walls on one side and by buildings such as urban commercial and residential buildings on the other side, the current total width is limited, and lo...

[0002] The high-quality development of my country's economy and society, the continuous growth of urban car ownership and the increasing living standards of the people have further put forward higher requirements for the number of motor vehicle lanes and the width of the slow traffic system on urban roads; due to urban development and planning adjustments, The functional orientation of some riverside roads has changed, the road grade has been improved, and the width of the planned road has increased; while urban riverside roads are often restricted by dikes or flood walls on one side and by buildings such as urban commercial and residential buildings on the other side, the current total width is limited, and local The road section is difficult to meet the width requirements of urban road reconstruction and upgrading; there are no relevant regulations on this situation in the current regulations; in the practice of urban riverside road reconstruction, in the case of limited road width, it is generally adopted to partially cancel non-motorized lanes, shrink Measures to reduce road function, such as narrow sidewalk width, affect the quality of riverside roads
