Description

Ecological gutter

technical field

The utility model relates to the field of road engineering, in particular to an ecological side ditch.

Background technique

The side ditch is a longitudinal ditch set on the outside of the excavated roadbed or the outside of the slope toe of the low embankment to collect and remove a small amount of surface water within the range of the roadbed and flowing to the roadbed. Now most road cutting side ditches in China are rectangular or trapezoidal Mortar side ditch.

Although the construction of the mortar side ditch is relatively simple, it is not good for the visual aesthetics of driving. Therefore, people design the ecological side ditch. The topography and natural ring are coordinated to create a better road driving environment.

At present, the Chinese patent with the publication number CN205313950U discloses a kind of ecological gutter with purification function, which includes an ecological gutter body for collecting road surface runoff, the upper side of the ecological gutter body is a water inlet, and the bottom is provided with a water collection system, the water collection hole of the water collection system is arranged at the bottom of the ecological side ditch body and facing the water flow direction of the ecological side ditch body, and the ecological side ditch body is sequentially provided with a planting soil layer, pebbles, etc. from the water inlet to the water outlet hole layer, vermiculite layer and gravel layer.

Although this kind of ecological side ditch with purification function can reduce the impact of pollutants on natural water to a certain extent, protect the water body environment and save water resources, but because it only drains water through the ditch body, it is subject to heavy rainfall when there is a lot of precipitation. Due to the limitation of drainage speed, if the ecological side ditch is too late to drain, the accumulated water will overflow and affect the road surface.

Utility model content

The purpose of the utility model is to provide an ecological side ditch, which has the advantages of being able to drain water quickly and not easily form a large amount of accumulated water that will affect the road.

The above-mentioned technical purpose of the utility model is achieved through the following technical solutions:

An ecological side ditch, including a ditch body, the ditch body includes a plain soil backfill layer, the plain soil backfill layer is sunken downward to form a channel, and several water distribution pipes extending vertically toward the ground below are arranged in the channel, and the plain soil backfill There is a drainage pipe connected to the river in the layer. The water distribution pipe includes a water inlet and a water outlet.

With this setting, the water level of the rainwater in the ecological side ditch gradually rises during rainfall. When the precipitation is small, the rainwater is first discharged into the water distribution pipe from the water guide hole set on the side of the water distribution pipe, and then discharged from the seepage port to the surrounding soil. When the precipitation gradually increases, the collected rainwater can enter the drain pipe from the water inlet of the water distribution pipe and be discharged into the river from the drain pipe to reduce the drainage pressure of the channel. When the precipitation is large and the drain pipe overflows When the accumulated water cannot be discharged, the water level in the ditch body rises, and the entire ditch body can be used as a drainage channel for rainwater. At the same time, the plain soil backfill layer can also absorb part of the accumulated water, thereby further increasing the drainage rate and reducing the accumulated water. reduce the impact of accumulated water on the road surface and roadbed.

Further setting: the water distribution pipe is provided with a rain cap, and the rain cap is fixed on the water inlet by several fixing rods arranged around the water distribution pipe.

In this way, since the water inlet of the water distribution pipe is set upward, it is easy for stones, fallen leaves and other impurities to enter the water distribution pipe from the water inlet during use, which will cause blockage of the water distribution pipe and drain pipe. and fallen leaves are blocked outside the water inlet, and the setting of the fixed rod separates the rain cap from the water inlet by a certain distance, so that the drainage effect of the water inlet is not hindered.

Further setting: the drainage pipe is provided with several seepage openings along its extending direction.

With such a setting, when the precipitation is large and there is too much water in the drainage pipe, all the accumulated water will be discharged into the river, which will cause the river to be overburdened and easily cause flood disasters. On the way to the river, it seeps into the soil layer through the seepage hole, so as to share most of the pressure of the accumulated water discharge, and also provide moisture for the soil layer to keep the soil moist.

Further setting: the seepage openings are distributed along the drainage pipe in two rows arranged on a symmetrical vertical plane, and an included angle of 120° is formed between the two rows of seepage openings.

With this setting, when the precipitation is large, it is inevitable that a little sediment will enter the drain pipe from the water inlet. If the seepage port is set directly below the drain pipe, the sediment will block the seepage port after long-term use, causing the drainage pipe to be damaged. For the obstruction of seepage, set the seepage ports into two symmetrical rows and form an included angle of 120°, which can make the sediment deposit at the bottom of the pipe, and prolong the service life of the seepage ports on the drainage pipe without hindering the seepage effect of the seepage ports.

Further setting: both the seepage opening and the water guide hole are covered with at least three layers of geogrids.

With this arrangement, since the water seepage outlet is buried in the soil, and the water guide hole is close to the plain soil backfill layer, when there is a lot of precipitation, the external sediment will easily enter the water guide hole, causing the water guide hole to be blocked and hindering the entire ecological edge. Therefore, installing at least three layers of geogrids can prevent sediment from blocking the water guide holes and seepage outlets, and achieve a better use effect.

Further setting: the ditch body is provided with several layers of anti-seepage geotextiles on the roadbed side close to the road.

In this way, since the plain soil backfill layer will absorb a large part of the accumulated water, the plain soil backfill layer will always be kept moist, and too much water will erode the roadbed and cause damage to the roadbed. Geotextiles can prevent the accumulation of water in the plain soil backfill layer from eroding the roadbed and preventing damage to the roadbed.

Further setting: the outlet of the water distribution pipe is covered with a filter layer.

With such a setting, when the precipitation is too large and a high level of water is formed in the ditch, the water will easily contain too much sand and gravel. At this time, the water will enter the drain pipe from the water inlet and cause excessive sediment accumulation. , It is easy to cause the blockage of the pipe. Setting the filter layer can block the sediment, thereby prolonging the time of the blockage of the drain pipe and increasing its service life.

Further setting: the seepage opening is set in the shape of a circular platform, and the end with a larger diameter is set close to the center of the water distribution pipe.

In such a setting, since the water needs to be drained from the inside of the pipe to the outside, setting the seepage port into a circular frustum shape can reduce the seepage of water into the pipe from the soil layer to a certain extent, and at the same time increase the pressure at the seepage port during drainage, thereby increasing the drainage effect.

Further setting: the drain pipe is a corrugated pipe, and the seepage opening is located on the crest of the corrugated pipe.

In this way, the drainage pipe is a corrugated pipe, and the water in the pipe will first fill the pores at the wave crest, while the seepage opening is located at the wave crest, and the water in the seepage pipe seeps outward under the action of water pressure, and the water seepage at the wave crest is conducive to internal moisture. discharge, and to a certain extent, prevent the entry of external water, and secondly, the corrugated structure of the bellows effectively improves its external pressure strength.

Preferably, the surface of the trench is provided with a green belt layer.

In this way, the setting of the green belt layer can increase the environmental protection effect of the whole city on the one hand, and on the other hand, it can optimize the driving environment of the road and improve the driving experience of the public. At the same time, the plants in the green belt can consume a lot of accumulated water to achieve a more Good drainage effect.

In summary, the utility model has the following beneficial effects:

When the precipitation is small, the rainwater is first discharged into the water distribution pipe from the water guide hole set on the side of the water distribution pipe, and then discharged from the seepage hole to the surrounding soil. When the precipitation gradually increases, the collected rainwater can be discharged from the drain pipe In the river, when there is a large amount of precipitation and the drainage pipe overflows and cannot discharge the accumulated water, the entire ditch body can be used as a rainwater discharge channel, thereby further increasing the drainage rate, reducing the amount of accumulated water, and reducing the impact of accumulated water on the road surface. and the influence of the subgrade.
