Description

Technical Field

[0001] The utility model relates to a central greening dividing belt structure of a municipal road. Background Art

[0002] A central green belt (referred to as a belt) is usually set up in the middle of municipal roads to achieve urban greening while avoiding oncoming collisions between two-way traffic.

[0003] Since municipal roads are paved in dark colors with good heat absorption capacity, the road surface temperature is very high in summer, even reaching over 60°C in extreme cases, causing a large amount of water evaporation from the green plants in the dividing strips. In continuous dry weather, it is necessary to replenish water to the green plants.

[0004] The existing method of replenishing water for green plants is to use a watering vehicle to drive along the dividing strip and spray water on the dividing strip while driving, which has the following defects:

[0005] 1) Most of the water is absorbed by the surface soil of the dividing zone, and the water on the surface of the dividing zone is particularly susceptible to evaporation and loss due to high external temperatures, resulting in low utilization rate of water resources.

[0006] 2) Sprinkler trucks driving at low speeds on the lane for a long time can easily cause traffic jams.

[0007] 3) It consumes fuel and requires two people, a driver and a water-dryer, to operate, resulting in high water replenishment costs. Utility Model Content

[0008] The purpose of the utility model is to provide a central green belt structure for a municipal road. The utility model has the advantages of high water resource utilization rate when replenishing water to green plants, no traffic congestion, low water replenishment cost and good water replenishment effect.

[0009] The technical solution of the utility model: a central green belt structure of a municipal road, wherein a main water pipe with one end closed is provided on the surface of the dividing belt, the direction of the main water pipe is parallel to the direction of the dividing belt, a plurality of branch water pipes are buried in the soil layer of the dividing belt, the branch water pipes are connected to the main water pipe through a vertical control pipe, an annular control panel is provided in the control pipe, and a float is provided below the control panel to match the gap with the control pipe.

[0010] In the aforementioned structure of the central green belt of the municipal road, the main water pipe is close to one side of the belt, and the branch water pipe runs horizontally, and the direction of the branch water pipe is parallel to the width of the belt.

[0011] In the aforementioned municipal road central green belt structure, the bottom of the control panel is provided with a spherical surface that cooperates with the floating ball.

[0012] In the aforementioned structure of the central green belt of the municipal road, the main water pipe is composed of a plurality of short pipes connected in series, and a three-way joint for connecting the control pipe is provided between adjacent short pipes.

[0013] In the aforementioned structure of the central green belt of the municipal road, the control pipe is connected to the branch water pipe through an elbow.

[0014] In the aforementioned structure of the central green belt of the municipal road, the extended end of the branch water pipe is closed, and a plurality of water outlet holes are provided at the bottom of the branch water pipe.

[0015] In the aforementioned central green belt structure of the municipal road, the distance between the branch water pipe and the surface of the belt is 20-40 cm.

[0016] In the aforementioned structure of the central green belt of the municipal road, a cylindrical float is provided below the floating ball, and the float is gap-matched with the control tube.

[0017] Compared with the prior art, the utility model sets a main water pipe on the existing dividing strip, connects a plurality of branch water pipes buried underground in the dividing strip to the main water pipe, and water enters the dividing strip through the main water pipe and the branch water pipe to moisten the underground soil in the dividing strip. Since the underground soil temperature is relatively constant and low, the supplemented water is not easy to evaporate and lose, thereby improving the utilization rate of water. When replenishing water, the main water pipe of Ajing can be connected to the water source, which will not cause traffic jams, and does not need to consume fuel. It can be operated by one person, and the cost of replenishing water is low. There is a float in the control pipe between the main water pipe and the branch water pipe, which can make the water intake of each branch water pipe uniform, ensure that the water replenishment at various places along the dividing strip is relatively uniform, and there will be no excessive water replenishment in local areas that causes waterlogging to kill green plants, and there will be no insufficient water replenishment in local areas that causes drought to kill green plants, and the water replenishment effect is better. Therefore, the utility model has the advantages of high water resource utilization rate when replenishing water to green plants, no traffic jams, low water replenishment cost and good water replenishment effect.

[0022] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0023] Example. The structure of the central green belt of a municipal road, such as Figure 1 As shown, a main water pipe 1 with one end closed is provided on the surface of the dividing strip, and the direction of the main water pipe 1 is parallel to the direction of the dividing strip. A plurality of branch water pipes 2 are buried in the soil layer of the dividing strip. The spacing of the branch water pipes 2 is determined according to the variety of green plants on the dividing strip. The spacing of plants with developed root systems can be larger. The branch water pipes 2 are connected to the main water pipe 1 through a vertical control pipe 3. An annular control panel 4 is provided in the control pipe 3. A floating ball 5 is provided below the control panel 4. A cylindrical float 10 is provided below the floating ball 5. Both the floating ball 5 and the float 10 are thin-walled hollow structures. A spherical surface 6 matching the floating ball 5 is provided at the bottom of the control panel 4. The inner diameter of the control pipe 3 is 2.5 cm, the diameter of the floating ball 5 is 2.2 cm, and the diameter of the float 10 is 2.2 cm.

[0024] The main water pipe 1 is close to one side of the dividing strip, and the branch water pipe 2 is horizontally oriented, and the direction of the branch water pipe 2 is parallel to the width direction of the dividing strip. From the projection direction of the horizontal plane, the two ends of the branch water pipe 2 are close to the two sides of the width direction of the dividing strip. The buried depth of the branch water pipe 2 is 20-40cm.

[0025] The main water pipe 1 is composed of a plurality of short pipes connected in series, and a three-way joint 7 connected to the control pipe 3 is arranged between adjacent short pipes. The control pipe 3 is connected to the branch water pipe 2 through an elbow 8.

[0026] The extended end of the branch water pipe 2 is closed, and a plurality of water outlet holes 9 are provided at the bottom of the branch water pipe 2. The diameter of the water outlet holes 9 is 3 mm.

[0027] The branch pipe 2, the tee joint 7 and the elbow 8 are all made of hard PVC. The short pipe is made of soft PVC. The control pipe 3, the control panel 4, the float 5 and the float 10 are all made of stainless steel.

[0028] Working principle: when there is no need to replenish water to the green plants, the main water pipe 1 does not flow water, and under the action of gravity, the float 5 and the float 10 are located at the bottom of the control pipe 3.

[0029] When replenishing water to green plants, the unsealed end of the main water pipe 1 is connected to tap water, and the tap water flows along the main water pipe 1 into each control pipe 3, passes through the float 5, the float 10, and the elbow 8 into the branch water pipe 2, and is discharged from the water outlet 9. Due to the presence of a certain water pressure in the tap water, the tap water enters the branch water pipe 2 at a faster speed, and the water outlet 9 is small, so the tap water entering the branch water pipe 2 has no time to be discharged, and the tap water accumulates in the control pipe 3, and the liquid level rises, driving the float 10 and the float 5 to rise until the float 5 enters the spherical surface 6 and contacts the control board 4, preventing the tap water from continuously entering the branch water pipe 2. After a part of the tap water in the branch water pipe 2 flows out and the liquid level in the control pipe 3 decreases, the water in the main water pipe 1 can enter the branch water pipe 2 again. During the entire water replenishment process, the float 10 and the float 5 rise and fall periodically, and the water in the main water pipe 1 enters the branch water pipe 2 periodically.

[0030] The purpose of setting the control pipe 3 and the float 5 is that the main water pipe 1 is long, and the water pressure of the tap water entering each branch water pipe 2 gradually decreases along the flow direction of the water, resulting in uneven water replenishment. The green plants near the end of the main water pipe 1 cannot be fully replenished, while the green plants near the water inlet end of the main water pipe may be over-watered. By setting a float 5 in each control pipe 3, it is possible to achieve periodic water inflow to each branch water pipe 2, and the water inflow of each branch water pipe 2 is uniform.

[0031] The purpose of setting the float 10 is to increase the buoyancy of the float ball 5. When the inner diameter of the control tube is large, the float 10 may not be required.

[0032] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", etc., indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.
