Description
Technical Field
The utility model belongs to the technical field of road drainage, and particularly relates to a road side drainage structure suitable for collapsible loess areas.
Background
The road side is usually paved with side ditches along the road direction at two sides of the road surface to guide away the rainwater or running water on the road surface.
The conventional design has the advantages that vertical construction joints exist between the concrete pavement surface layer and the side walls of the side trenches, the joints are formed between the edges of the pavement and the side walls of the side trenches, rainwater and surface running water infiltrate downwards through the joints, the roadbed is easy to be soaked by water, the structure is damaged and unstable, the pavement collapses, and great economic loss and potential safety hazards are caused. According to the field construction experience for many years, the pavement collapse condition is easy to occur in the side ditch form especially in collapsible loess areas.
Disclosure of Invention
In order to overcome the technical problems, the utility model provides a highway side drainage structure suitable for collapsible loess areas, which prevents rain from seeping under water.
The utility model adopts the following technical scheme:
the utility model provides a highway limit drainage structures suitable for collapsible loess area, includes the stereoplasm side ditch that links to each other with cast-in-situ concrete road surface, the side ditch includes diapire, the left side wall that keeps away from cast-in-situ concrete road surface and the right side wall that is close to cast-in-situ concrete road surface, diapire, left side wall and right side wall three enclose into water drainage tank, right side wall is lower for left side wall its height, the marginal upper layer of cast-in-situ concrete road surface widens to the left and extends and cover right side wall.
Preferably, the side ditch is a masonry side ditch or a cast-in-situ concrete side ditch.
Preferably, the height difference between the right side wall and the left side wall is 100mm.
Preferably, the side surface of the edge of the cast-in-situ concrete pavement is flush with the inner surface of the right side wall.
Preferably, the top end surface of the right side wall is lower left and higher right.
Preferably, the top end surface of the right side wall is provided with a bulge along the groove direction.
Compared with the prior art, the utility model has the beneficial effects that:
the utility model aims to eliminate the water seepage through joint between the side ditch and the cast-in-situ concrete pavement, prevent rainwater and surface running water from seeping downwards through the joint, reduce the height of the side ditch close to the side wall of the pavement, enlarge the casting width of the pavement concrete, cover the side wall of the lowered side ditch, eliminate the vertical water seepage joint between the side ditch and the cast-in-situ concrete pavement, and lead the rainwater or the running water on the cast-in-situ concrete pavement to directly flow into the drainage groove of the side ditch to be led away, thereby preventing the underwater seepage and achieving the effect of solving the problem of water damage of the roadbed in collapsible loess areas.

Detailed Description
Embodiments of the present utility model are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the utility model.
Example 1
As shown in figure 1, the highway side drainage structure suitable for collapsible loess areas comprises a hard side ditch 2 connected with a cast-in-situ concrete pavement 1, wherein the side ditch 2 is a stone side ditch or a cast-in-situ concrete side ditch, the side ditch 2 comprises a bottom wall 22, a left side wall 23 far away from the cast-in-situ concrete pavement 1 and a right side wall 21 close to the cast-in-situ concrete pavement 1, the bottom wall 22, the left side wall 23 and the right side wall 21 enclose a drainage channel, the right side wall 21 is lower relative to the left side wall 23, the height difference between the right side wall 21 and the left side wall 23 is 100mm, the upper edge layer of the cast-in-situ concrete pavement 1 is widened leftwards to cover the right side wall 21, and the edge side surface of the cast-in-situ concrete pavement 1 is flush with the inner surface of the right side wall 21.
Highway limit drainage structures suitable for collapsible loess area, principle:
rainwater or running water on the cast-in-situ concrete pavement 1 directly flows into the drainage groove of the side ditch 2 to be led away, and does not pass through a vertical joint between the cast-in-situ concrete pavement 1 and the right side wall 21 any more, so that underwater seepage is prevented, and the problem of roadbed water damage disease in collapsible loess areas is solved.
Example two
As shown in fig. 2, the present embodiment differs from the first embodiment in that the top end surface of the right side wall 21 is lower left and higher right.
Principle of:
further, the inclined surface is utilized to prevent rainwater from penetrating into the gap between the cast-in-situ concrete pavement 1 and the right side wall 21 of the side ditch 2 in the transverse direction.
Example III
As shown in fig. 3, this embodiment differs from the first embodiment in that the top end face of the right side wall 21 has a projection 24 in the groove direction.
Principle of:
further, rainwater is further prevented from penetrating into the side wall of the side ditch 2 from the transverse direction and the depth direction through the gap between the cast-in-situ concrete pavement 1 and the right side wall 21 of the side ditch by the bulge 24.
While embodiments of the present utility model have been shown and described, it will be understood by those of ordinary skill in the art that: many variations, modifications, substitutions and alterations are possible to the above embodiments without departing from the spirit and principles of the utility model, the scope of which is defined by the claims and their equivalents.
