With the modernization of the city, elevated roads are being used more and more. The isolation belt under the elevated road is generally planted with green plants. However, the problem of watering the green belt under the elevated road has not been well resolved. On the one hand, the rainwater on the elevated road cannot be used rationally and is discharged directly to the urban sewer system; on the other hand, the greening under the elevated road The belt cannot obtain natural precipitation, and needs to be irrigated with tap water on a regular basis, resulting in a great waste of water resources, manpower and material resources.

At present, some people have tried to use rainwater to irrigate the green belt under the elevated road. For example, the Chinese utility model patent No. ZL200720067638.2 discloses "a device for using rainwater to irrigate the green belt under the elevated road". and the water pump, the water storage tank is set below the ground, the water inlet pipe of the water storage tank is the downpipe of the original elevated, the water outlet pipe of the water storage tank is set on the lower side of the water storage tank, and is connected with the water pump through a valve. A water outlet hole is also arranged on the upper side of the water pipe, and the water outlet hole communicates with the sewer. The downside of this setup is that it needs to pump the collected rainwater, which still requires electricity. Another technology is a Chinese utility model patent whose patent number is ZL 200520014553.9, which discloses "a simple rainwater irrigation system", which includes a water storage tank (2) with a water inlet (1) and a water outlet (8). ), the water level control switch assembly placed in the reservoir (2) isolates the water outlet (8) from the inner cavity of the reservoir (2), and the seepage groove (6) that can seep water on the side is passed through the connecting pipe (7) It is connected with the water outlet (8), and the top of the seepage tank (6) is provided with an opening. The irrigation system can use rainwater to irrigate greenery without power resources. But the defect of this patented technology has: 1) control valve needs to be set, not only manufacture, complicated operation, and rainwater in the reservoir can be discharged in the seepage tank when there is a lot of rain, and if there is no rain for a long time, the seepage tank There is no water inside, and if there is a little rain or the rainfall is not enough to turn on the water level control switch, then the irrigation will not be obtained when the irrigation is most needed, otherwise it may cause waterlogging; 2) The filter layer made of non-woven fabric is arranged on the On the inner surface of the water seepage tank, the filter layer is also provided with through holes corresponding to the through holes opened on the side of the water seepage tank. This kind of structure is theoretically feasible, but in the environment under this silt garbage tool, these The hole is very likely to be blocked; 3) The seepage branch line has a very long spray or seepage pipeline, and it is easy to block due to the rainwater on the road surface with more mud.

Detailed ways

As shown in Fig. 1 and Fig. 2, the irrigation system of this embodiment includes the original drainage pipe 1, and the drainage pipe is under the elevated road 10 and is close to the bridge pier 9. The feature of this example is that the lower end of the original drainpipe is connected with a diameter-identical transformation drainpipe 3 with an elbow, and the lower end of the transformation drainagepipe stretches into the top of the reservoir 2 arranged on the ground. The water storage tank is rectangular and is arranged on the side of the pier near the green belt 11. The top of the water storage tank is covered with a water storage tank cover plate 6. The cover plate is composed of several pieces, each weighing no more than 20 kg, which is convenient for regular cleaning of the water storage tank. Mud and debris.

This example is provided with 2 watering outlet pipes 4 leading to the outside green belt 11 on the bottom side of the reservoir. This diameter can not be greater than the diameter of original drainpipe 1, can select according to the rainwater situation of city and plant characteristic, when rainwater duration is short, the water yield that plant needs is big, can select larger diameter for use. During construction, a hole is directly drilled on the side of the water storage tank 2, and the water outlet pipe 4 is directly inserted into the hole, and the gap between the pipe and the installation hole is sealed with waterproof mortar. , the outlet pipe is set at a distance of 100mm from the bottom of the pool, and the sludge layer 7 can be deposited on the bottom of the water storage tank.

The water storage tank 2 is vertically provided with a waste water pipe 5 whose lower end is connected to the original urban sewer system, and its upper end is close to the top of the water storage tank. After the rainwater is fully stored, the excess rainwater will be drained away in time to prevent the rainwater from flooding and damaging the green belt during the rainstorm.

As shown in Figure 3, this example offers two irrigation ditches 8 in the middle of the green belt 11 between two piers, and its quantity should be equated with the described irrigation outlet pipe 4, can determine according to the width of the green belt. The irrigation ditch 8 extends from the pier slope with the water storage tank to the bridge pier without the water storage tank, and the longitudinal slope is not less than 0.5%. The trench can be dry-laid with tiles (or other building materials) to form a trapezoidal section. The function of the dry-laid material of the trench is to ensure that the soil at the bottom and sides of the trench will not be scoured. There is no requirement for the water permeability of the material, and rainwater can pass through the dry The gaps between tiles (or other building materials) seep into the green belt soil. There are 12 curb slope protections on both sides of the green belt.

When rainwater accumulates on the elevated road 10, the rainwater flows into the storage tank 2 along the original drainage pipe 1 and the modified drainage pipe 3. When the water in the pool is higher than 10mm, the rainwater will flow into the irrigation ditch 8 through the irrigation outlet pipe 4. , and then infiltrated into the soil of the green belt 11; when the rainfall was too large, when approaching the top of the water storage tank, excess water was discharged into the original urban sewer system from the discarded water pipe 5, so as not to submerge and damage the green belt.
