Problems solved by technology

[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

Embodiment Construction

[0027] In order to make the purpose, technical solution and advantages of the invention clearer, the invention will be further elaborated below in conjunction with the accompanying drawings.

[0028] A method for reconstructing an existing urban road jointly built with a flood wall and a back abutment, comprising the following steps:

[0029] Excavate the backfill of some road sections; if there is a narrow local road width in urban riverside roads, excavate the backfill next to the narrow section of the road.

[0030] Reinforce the current flood control wall; in order to protect the safety of urban flood control and ensure the stability of the current flood control wall, the current flood control wall must be reinforced after excavating the current situation of the local road section. 1 reinforcement, the reinforcement of the back heel plate 4 of the flood control wall, reinforced concrete is used for the reinforcement of the vertical wall 1 of the flood control wall and the ...

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...
