Problems solved by technology

However, the high-level side ditch still has the following disadvantages in practical application: the high-level side ditch is excavated between the baffle and the mountain, which leads to an increase in the excavation of the roadside mountain and damages the vegetation on the mountain, resulting in a waste of land resources and increasing the project cost.

Embodiment 1

[0036] The Z-shaped retaining structure and superimposed side ditch structure involved in the present invention are shown in figure 2 , Figure 4 and Figure 5 As shown, a road with protection and superimposed side ditch includes a Z-shaped protection body 1 and a superimposed side ditch body 2. The Z-shaped protection body 1 is installed on the outside of the road sill, and the superimposed side ditch body 2 Including the low side ditch 2a, the high side ditch 2b superimposed on the top of the low side ditch 2a, the low side ditch 2a is set between the road body 15 and the mountain body 16, and the high level side ditch 2b is set close to the mountain body 16;

[0037] The Z-shaped shielding body 1 includes a top plate 1a and a bottom plate 1c arranged horizontally. The top plate 1a is arranged above the bottom plate 1c. A side baffle 1b is obliquely arranged between the top plate 1a and the bottom plate 1c. The top of the side baffle 1b is connected to the right end of the...

Embodiment 2

[0042] See image 3 As shown, the main difference between embodiment 2 and embodiment 1 is that the filling part of the embankment can be buried between the top plate 1a and the guard plate 7, so that a green belt can be formed, and the green belt is arranged beside the road.

[0043] Preferably, the Z-shaped guard body 1 also includes a guard plate 7, the left end of the top plate 1a is provided with a mounting hole 8, and the lower end of the guard plate 7 is provided with a mounting post 9 corresponding to the mounting hole 8 of the top plate 1a, and the mounting post 9 is inserted into the installation holes 8, so that the guard plate 7 is vertically installed on the top plate 1a.

[0044] Preferably, the angle between the bottom plate 1c and the side baffle 1b is 70°-85°,

[0045] Wherein, a plurality of first tie bars 10 for embedding in soil are vertically arranged on the top plate 1a.

[0046] In actual application, the z-shaped retaining body 1 and the superimposed ...

Abstract

The invention discloses a highway with a retaining wall and superimposed side ditches, and relates to the technical field of highway engineering. The highway with the retaining wall and the superimposed side ditches comprises a Z-shaped retaining wall body and superimposed side ditch bodies, wherein the Z-shaped retaining wall body is installed on the outer side of a road bank; and the superimposed side ditch bodies comprise a low-level side ditch and a high-level side ditch superposed on the low-level side ditch, the low-level side ditch is arranged between a road body and a mountain body, and the high-level side ditch is arranged close to the mountain body. When a Z-shaped retaining wall structure in the combined structure is installed on the outside of the road bank, a concrete road body extends and is paved above the left end of a top plate, so that the width of a road surface is increased; when the road surface subsides, the anti-pressure measuring capability of the Z-shaped retaining wall structure can be improved due to the increase of friction between a bottom plate and a concrete base, and a retaining wall member can be prevented from shifting outward or even toppling; andwhen the superposed side ditch structure is applied to a highway, under the condition that the total occupied area of the road body, the side ditches and the mountain body is unchanged, the digging amount of the mountain body and the damage to vegetation can be reduced, and land resources are saved.

Description

technical field [0001] The invention relates to the technical field of highway engineering, in particular to a highway with protection and superimposed side ditches. Background technique [0002] With the rapid development of my country's economy, many original roads can no longer meet the increasing demand for vehicle traffic, making road widening the mainstream of road construction at this stage. [0003] Road sill protection is the main technology to provide safety guarantee for the stability of the roadbed and the reliable service life of the road. The traditional road sill protection usually adopts the form of retaining wall, and the gravel layer or concrete covering layer or block layer of the retaining wall is generally thin, and due to the long-term rolling of vehicles and the action of gravity on the road surface, the road body falls The pressure on the soil layer will lead to the settlement of the road surface, which will put pressure on the retaining wall, which ...
