Description

Prefabricated riser waste flow module and riser waste flow sponge device for roof rainwater disconnection

technical field

The utility model relates to a prefabricated standpipe waste flow module and a riser waste flow sponge device for disconnecting roof rainwater. It is suitable for the abandonment of the first rain on the roof of the building drainage area and the regulation, storage and collection of rainwater in the middle and late stages.

Background technique

Urban non-point source pollution is mainly produced by the showering and scouring of rainfall runoff. Urban rainfall runoff is mainly in the form of confluence and discharged through the drainage pipe network. The initial effect of runoff pollution is very obvious. For the drainage area, especially in the early stage of heavy rain, the pollutants deposited on the roof and the standpipe due to the rainfall runoff will suddenly wash into the drainage pipe network in a short period of time, which will cause siltation in the pipe network after a long time.

By setting the waste flow facility at the end of the building's rainwater standpipe, the initial rainwater on the roof can be cut off, and the later rainwater can be discharged into the sponge facilities such as the sunken green space through the water dustpan. This method embodies the sponge city concept of "infiltration, stagnation, storage, purification, utilization, and drainage". It starts from the source of pollution control, realizes the accumulation, infiltration, and transformation of rainwater in the community, and reduces the impact of non-point source pollution on the underlying surface of the city. Pollution and pressure on the drainage network.

At present, the commonly used roof rainwater disconnection mainly includes the following types:

1. Use a water dustpan to divert roof rainwater into sponge facilities. Through the interception of rainwater, the runoff that was directly discharged into the rainwater pipeline system is stagnated and stored to reduce the discharge of runoff. The general method is to set up grass planting ditches, ecological retention ponds, and high flower beds at the end of the rainwater system. This method is The rainwater in the early, middle and late stages of the rainfall process is fully collected and stored, but there is a lack of waste flow that pollutes the initial rainwater.

2. Use electric mode to control the discarding flow. By accumulating initial rainwater, it is manually discharged later. This method can precisely control the waste flow, but the current market is chaotic, the quality is uneven, the general cost is high, the power consumption is high, it is not environmentally friendly, and the service life is short, which is prone to problems.

3. Set up a simple abandonment well at the end of the rainwater system. The initial rainwater is collected and discharged into the sewage pipe network system, and the later rainwater is collected for later use. This method needs to consider the issue of land occupation, and the vertical relationship of the site, slope, water catchment division, etc. must be considered during the setting process, which is not conducive to later promotion and implementation.

In the above designs, the method of initial rainwater abandonment has been considered. Method 1 has little effect on initial rainwater abandonment. Method 2 and 3 are both suitable for use at the end of the rainwater system with a large catchment area and sufficient rainfall collection. Consider initial stormwater abandonment from source risers within small catchments.

Detailed ways

As shown in FIG. 1 , this embodiment is a riser-discarding sponge device for roof rainwater disconnection, which has a prefabricated riser-discarding module, a rainwater storage sponge module, and a rainwater riser 10 placed outside the building.

As shown in Figure 2, the prefabricated standpipe abandonment module has a box body, and a partition 11 is arranged in the box, and a flow outlet 9 is opened on the partition 11. In the confluence chamber, the discharge port 9 on the bottom of the partition 11 is connected with the discharge pipe 8. A lever mechanism 5 is installed in the confluence chamber, and one end of the lever mechanism 5 is connected to the discharge port 9 that can close the discharge port The sealing block 6 impacted by the water flow of 9, the other end of the lever mechanism is connected to the adjustment block 7 (the adjustment block 7 of different weights can be set according to the diameter of the rainwater standpipe 10 and the catchment area), and the top of the box is connected with the flow through it. The water flow can impact the water inlet pipe 1 of the sealing block 6, and the side of the box body is connected with the water outlet pipe 2 connected with the confluence chamber, and the water outlet pipe 2 faces the ground through the elbow 201. Wherein, the upper surface of the partition 11 is inclined to the discarding outlet 9 thereon, and is in the shape of a funnel; the shape of the sealing block 6 is adapted to the shape of the upper surface of the partition 11 .

A filter hanging basket 3 is installed in the confluence chamber corresponding to the water inlet pipe 1, which is used to cut off large particles of pollutants in the initial rainwater. The side of the box body is provided with an inspection port 4 corresponding to the filter hanging basket 3, so that the filter hanging basket 3. Pull out directly from the inspection port 4 and facilitate the cleaning of initial rainwater pollutants in the filter screen hanging basket 3, and facilitate the maintenance of the filter screen hanging basket 3 at the same time.

The rainwater storage sponge module is arranged below the elbow 201, including a water dustpan 12 placed on the ground below the elbow 201, and a sunken green space 14 connected to the water dustpan 12 through gravel 13. Wherein the water dustpan 12 is a protective block for avoiding the ground from being washed by rainwater, and its material is fine stone concrete mortar plastering; the sunken green space 14 is the simplest form of rainwater regulation and storage facility.

In this embodiment, the water inlet pipe 1 of the prefabricated standpipe abandonment module is connected to the lower end of the rainwater riser 10, and prefabricated riser abandonment modules of different sizes are prefabricated according to different rainwater standpipe 10 pipe diameters and water volumes; The discarded flow pipe 8 of the flow module is connected to the sewage pipe network system. The rainwater storage sponge module can store rainwater in the middle and late stages of the rainwater standpipe 10, and utilize the effects of vegetation, soil and microorganisms to intercept small-flow rainwater runoff.

The present embodiment divides 4 kinds of working conditions, and its working principle is as follows:

In sunny working conditions, if the rainwater standpipe 10 has mixed flow, the sewage enters through the water inlet 1, usually with a small amount of water; a small amount of sewage is filtered through the pull-out filter hanging basket 3 to remove large particles, and the sewage enters the waste water through the outlet 9. Flow pipe 8, thereby discharging into the sewage pipe network system.

In the case of initial rain, the amount of rainwater collected by the initial rain is small, and it enters from the water inlet 1, and is filtered through the pull-out filter hanging basket 3. After removing large particles in the initial rain, the water flows to the sealing block 6 through the lever mechanism 5, and the water flow continues to impact Sealing block 6, because the impact of water flow is small, and according to the amount of rainfall, the rainwater abandonment flow is controlled, so the initial rain of the abandonment flow enters the abandonment flow pipe 8 through the abandonment flow port 9 and is discharged into the sewage pipe network system.

In the middle and late rainwater conditions, as the rainfall gradually increases, the impact of rainwater on the sealing block 6 through the lever mechanism 5 is increasing. According to the principle of leverage, the greater the impact of the water flow, the more the sealing block 6 sinks. At the same time, the lever mechanism in the box The adjustment block 7 connected to one end of the 5 rises gradually to a preset height, thereby controlling the sinking of the sealing block 6 until the discharge outlet 9 is completely sealed, and the rainwater level rises to the position of the outlet pipe 2 before being discharged, that is, the roof rainwater is discharged from the rainwater standpipe 10 Discharge, enter the prefabricated riser waste flow module from the water inlet 1, enter the gravel 13 through the water dustpan 12, flow into the sunken green space 14, and store and store rainwater; further, from the prefabricated riser waste flow module to the rainwater storage The sponge module realizes the accumulation, infiltration and transformation of rainwater inside the community, reducing the pollution of non-point source pollution on the underlying surface of the city and the pressure on the drainage pipe network.

After the rainfall ends, the amount of rainwater in the prefabricated riser abandonment module will gradually decrease, and the sealing block 6 at one end of the lever mechanism 5 in the box will gradually lift up and gradually return to its original position, thereby releasing a small amount of remaining rainwater in the prefabricated riser abandonment module .

In this embodiment, the pull-type filter hanging basket 3 can be cleaned regularly, and can be directly pulled and collected into the trash can, which can completely avoid the phenomenon that the waste in the waste flow module of the prefabricated standpipe blocks the flow opening.

The above is only an embodiment of this utility model, and does not limit the patent scope of the utility model. Any equivalent structure or equivalent process conversion made by using the utility model specification and accompanying drawings, or directly or indirectly used in other Related technical fields are all included in the patent protection scope of the present utility model in the same way.
