Description

Rain sewage inspection shaft

Technical Field

The invention belongs to the technical field of inspection wells, and particularly relates to a rainwater and sewage inspection well.

Background

The municipal drainage pipe network mainly mixes or merges the rainwater and the sewage; most towns do not have perfect rain and sewage diversion systems, and the capacity of a drainage system is insufficient.

Along with the high-speed development of urbanization, in the expansion process of cities and towns, some enterprises and residents are convenient to draw, sewage is directly discharged into a rainwater pipeline to form rainwater and sewage mixed flow, and the mixed flow water is finally discharged into a river channel through the rainwater pipeline, so that pollutants in the river channel are continuously deposited, black and odorous sludge and black and odorous water are formed, and the urban environment and the physical and psychological health of the residents are influenced.

In addition, in some complex environment areas of cities and towns, such as pollution concentration areas of seafood markets, farmer markets and the like, due to the fact that underground drainage pipe networks are constructed laggardly, original underground pipe networks are silted up, the pollution discharge function is weakened or invalid, pollutants such as sewage, animal viscera and the like generated in the areas cannot be discharged through the sewage pipe networks, but flow into the rainwater grate through ground runoff, and are discharged into a river channel through a rainwater pipe, and the river channel pollution is caused.

In conclusion, the original underground drainage pipe network system in cities and towns cannot meet the increasing expansion and development requirements of cities and towns, along with the high-speed development and construction of urbanization, supporting facilities such as rainwater-sewage separation, expansion and perfection of the original underground pipe network and the like are also urgently required to be synchronously constructed, and the underground drainage pipe network in cities and towns serves as an excretion system in cities and towns, so that the sewage and wastewater generated in the production and life processes of cities and towns cannot bear the transportation mission at all times. After being collected through a water falling port, sewage and wastewater generated in the urban production and living process passes through a sewage transportation channel such as an inspection well, a sewage pipeline, a lifting pump station and the like, and is finally conveyed to a sewage treatment plant, and is discharged into a river channel or used for other reclaimed water utilization after being treated by the sewage treatment plant after reaching the standard; rainwater is collected through the rainwater grate and then is discharged into the river channel nearby through the rainwater pipeline.

Based on the situation, the invention provides the combined type rain sewage inspection well and the environment-friendly diversion method under the complex urban environment condition, and the rain sewage is effectively diverted by arranging the combined type rain sewage inspection well, so that the problems can be effectively solved.

The implementation mode is as follows: when the rain sewage collecting well is used, sewage generated in complex environments such as seafood markets, farmer markets and the like flows into the rain sewage collecting well 11 through surface runoff or drainage ditches in sunny days, solid garbage with larger diameter on the ground is filtered by the rain sewage collecting well cover 2 and then is blocked outside the inspection well, residual sewage and sand stones with smaller particle sizes enter the precipitation tank 5 of the rain sewage collecting well 11 along with the action of gravity, and sundries precipitated in the precipitation tank 5 can be periodically and manually removed. Through the sediment of a certain period of time, debris such as small-grain-size grit, earth and animal viscera deposit in 5 bottoms in sedimentation tank, along with sewage inflow, the sewage water yield increases gradually, and when the sewage water level was higher than two 43 bottommost of rain sewage collection well honeycomb ducts, sewage will be through two 43 outflow of rain sewage collection well honeycomb ducts. When the sewage that two 43 of rain sewage collection well honeycomb ducts flow through wane 19, two 43 outflow sewage of rain sewage collection well honeycomb duct are because the water yield is less, and wane 19 is down to the left side slope in the erodeing of little water yield, and sewage is through the fin 19 water conservancy diversion after the slope to the inspection shaft bottom. After sewage reaches the bottom of the inspection well body 1, the sewage is collected to the sewage pipe 4 under the guiding action of the slope surface 15 at the bottom of the inspection well body 1, and then is discharged into the municipal sewage pipe 4 network.

During the rainy day, when just beginning raining, the rainwater gets into rain sewage collection well 11 after ground converges, and this stage rainwater is because of being mingled with numerous ground surface source pollutants, nature with sewage, the flow is less, the sewage treatment mode like the treatment methods of the sewage that produces under the complex environment such as seafood market, farmer's market when fine. When the rainfall of the rainwater is gradually increased, the rainfall amount in the rainwater and sewage collecting well 11 rapidly rises, the rainwater gradually submerges the floating block 26 on the mounting frame 25, the floating block 26 drives the mounting frame 25 to move upwards after being subjected to buoyancy, the mounting frame 25 pulls the first water flow channel opening and closing plate 27 to slide relative to the second water flow channel opening and closing plate 28 through the pull rope 71, channels of a first rainwater and sewage flow hole 30 and a second rainwater and sewage flow hole 32 on the first water flow channel opening and closing plate 27 and the second water flow channel opening and closing plate 28 are closed, and the upper part of the rainwater and sewage collecting well 11 is separated from the lower sedimentation tank 5; meanwhile, the opening plate control module 47 receives a signal of upward movement of the mounting frame 25 and then controls the opening plate 38 to move upward to close the second rainwater and sewage collecting well diversion pipe 43, so that on one hand, water in the sedimentation tank 5 is fully kept stand to achieve the physical effect of separating sundries from sewage and is used for precipitating sundries, small-particle gravels, soil and waste animal viscera, hair, shells and the like in the seafood market or farmer market, and on the other hand, the sewage is prevented from entering the sedimentation tank 5 to flush out the sediments in the sedimentation tank 5 and enter the rainwater pipe 7; and the upper part of the rainwater and sewage collecting well 11 is under large water pressure, and rainwater at the first rainwater and sewage collecting well draft tube 16 flows to the right side of the wane 19 in a spraying manner. Under the action of water power, the wane 19 inclines to the right side, and rainwater flows to the rainwater pipe 7 through the inclined wane 19 to the right side and is discharged into the municipal rainwater pipe 7 network; after the rainwater stops and the mounting frame 25 moves downwards, the opening plate control module 47 receives a signal of the downward movement of the mounting frame 25 and then controls the drainage pipe opening plate 38 to move downwards, the second drainage pipe 43 of the rainwater and sewage collecting well is opened, and the obtained standing and precipitated sewage is drained from the sewage pipe 4.
