Further, the collecting tank 6 further comprises an overflow pipe 603, wherein the overflow pipe 603 is arranged on the upper portion of the side wall 601 of the collecting tank on the other side and used for discharging overflowed liquid to surrounding ditches under the condition of heavy rainfall, and the concentration content of the discharged rainwater pollutants is low, so that the water body is not polluted.
Further, collecting pit 6 still includes evacuation pipe 604 and automatic gate valve 605, evacuation pipe 604 sets up collecting pit lateral wall 601 bottom is close to the position of collecting pit bottom of the pool 606, and its inside supporting setting automatic gate valve 605 for automatically open and wait the evacuation in a period of time after the rain behind the rainwater behind the automatic closing of rainwater waste liquid in the collecting pit 6.
Preferably, the collecting tank side wall 601 and the collecting tank bottom 606 are made of grouted rubbles, and the collecting tank bottom 606 is coated with an anti-seepage agent to prevent secondary pollution caused by the infiltration of pollutants when leakage occurs in an accident.
In the embodiment, bridge deck rainwater or accident liquid firstly flows through the ground to gather to the vicinity of the water discharge opening 2, the water discharge opening 2 is designed to be circular, the diameter is 8-12cm, the preferred diameter is 10cm, a cast iron grid cover plate is adopted at the top of the water discharge opening 2 for rapidly discharging water, and the top surface of the water discharge opening 2 is 5-10cm lower than the bridge deck 8 for rapidly gathering water. The drain opening 2 is made of a steel pipe, and the bridge floor rainwater or accident liquid is collected into the drain pipe 3 through the drain opening 2 and the drain channel 4 and then enters the collecting tank 6 through the drain pipe 3.
Referring to fig. 2, the connecting port 5 is in an overflow mode, the joint of the water drainage channel 4 and the water drainage pipeline 3 is in butt joint, and certain connecting port gaps 9 are reserved, and the connecting port gaps 9 are distributed in a net shape. When the rainfall and the accident liquid runoff flow are within the design range, the water level of the liquid at the connecting port 5 cannot reach the lowest water level of the connecting port gap 9, and at the moment, the rainwater and waste liquid collected by the water discharge port 2 can be completely discharged into the collecting tank 6 for sedimentation; when rainfall and accident liquid flow are greater than the design runoff, excessive rainwater waste liquid will overflow through the connecting port gap 9, and the initial rainwater runoff containing high pollutant concentration is collected by the drainage pipeline 3 and enters the collecting tank 6, and the liquid discharged from the connecting port gap 9 is liquid after the scouring action of the initial rainwater, and the pollutant concentration is almost 0, so that the secondary pollution can not be generated by direct discharge. By adopting the connection mode, the problem that the pipelines of the water discharge opening 2 and the water discharge channel 4 are too large and impractical is avoided, the smoothness of water discharge can be ensured, the water discharge is practical and economical, the water discharge efficiency is improved, and the resources are saved.
Referring to fig. 3, the drainage channel 4 and the bridge floor 8 are welded together through pipe hoops 11 and reinforcing steel bars 10 embedded in the bridge floor 8.
Referring to FIG. 4, the collecting tank 6 is filled with water from the drain line 3, drained from the drain pipe 604, and overflowed from the overflow pipe 603. The function of the collecting tank 6 for collecting and treating the waste liquid rainwater is described in the following cases:
when the kind of intaking was the initial stage rainwater, the initial stage rainwater of collecting pit 6 can get rid of more particulate matter in the rainwater through independently depositing and adsorbent adsorption precipitation dual mode, and excessive rainwater then can overflow to irrigation canals and ditches all around through overflow pipe 603, promotes hydrologic cycle. After rain, the bridge deck rainwater runoff is drained through an automatic gate valve 605 and a drain pipe 604 to prepare for collecting sudden accident runoff at any time. The baffle 602 in the collecting tank 6 can deposit sundries in rainwater on the bottom 606 of the collecting tank, and can play a role in intercepting sewage.
When a pollutant leakage accident occurs, the leaked accident runoff is discharged into the collecting tank 6, at the moment, the automatic gate valve 605 is closed, the connection between the emptying pipe 604 and the outside is cut off, and correspondingly, the bridge management unit immediately organizes personnel to completely pump the accident runoff out of the tank truck and properly dispose the accident runoff.
When both of the above conditions occur, i.e., a contaminant leakage accident occurs in a rainy day, the automatic gate valve 605 is closed. Collect the waste liquid by outlet 2, initial stage waste liquid concentration is higher, and its water level can not reach the minimum water level of connector gap 9, and when the rainfall is great, the later stage rainwater is more, contains almost no pollutant in the rainwater this moment, when overflowing connector gap 9 department, will spill over through connector gap 9, has alleviated drainage pressure. When the sewage and waste liquid enter the collecting tank 6, chemical dangerous goods with density being lighter than that of water can float on the water surface and are blocked by the partition plate 602 and cannot overflow out through the overflow pipe 603; when the density of the chemical is greater than that of water, the chemical will settle on the bottom of the water or be adsorbed by the adsorbent reserved in the tank, and settle on the bottom 606 of the collection tank. Finally, the organization personnel of the bridge management unit completely draws the accident runoff away by the tank truck and properly disposes the accident runoff.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
