Combined type municipal inspection well

Abstract

The invention discloses a combined type municipal inspection well which comprises a rainwater inspection well and a sewage inspection well. The combined type municipal inspection well is characterizedin that rainwater openings are formed in the rainwater inspection well, the sewage inspection well is provided with a sewage pipe, a control box is arranged between the rainwater inspection well andthe sewage inspection well and is connected with a water barrier, a pressure sensor is arranged inside the control box, an inspection ladder is arranged in the control box, and the sewage inspection well and the rainwater inspection well are provided with inspection ladders. The combined type municipal inspection well has the advantages that the rainwater inspection well and the sewage inspectionwell are combined with each other, are excavated together and are simultaneously placed, and water can be drained via the sewage pipe by the water barrier under the control of the control box as soonas possible in heavy rain; the excavation pressures can be relieved, the work efficiency can be improved, and the drainage pressures of urban roads in stormy weather can be relieved to a great extentby the water barrier.

Description

technical field [0001] The invention relates to a drainage system in construction engineering, in particular to a combined municipal inspection well. Background technique [0002] At present, in order to avoid the mixed flow of rainwater and sewage, the inspection wells used by the municipal government are separated from the rainwater inspection wells and sewage inspection wells. The inspection wells at this stage are all prefabricated, so when constructing the inspection wells It is necessary to excavate the foundation pit first, and then place the prefabricated inspection well. The rainwater and sewage inspection wells are placed separately. During construction, not only two foundation pits need to be excavated, but also the danger of foundation pit collapse is easy to occur during the excavation process. . [0003] Now that the city is developing faster and faster, high-rise buildings have been built on both sides of the municipal road. When there is a heavy rain, the ra...

[0002] At present, in order to avoid the mixed flow of rainwater and sewage, the inspection wells used by the municipal government are separated from the rainwater inspection wells and sewage inspection wells. The inspection wells at this stage are all prefabricated, so when constructing the inspection wells It is necessary to excavate the foundation pit first, and then place the prefabricated inspection well. The rainwater and sewage inspection wells are placed separately. During construction, not only two foundation pits need to be excavated, but also the danger of foundation pit collapse is easy to occur during the excavation process.

[0003] Now that the city is developing faster and faster, high-rise buildings have been built on both sides of the municipal road. When there is a heavy rain, the rainwater pipes on the municipal road obviously cannot drain the water from the road quickly, and there will be water on the road. , causing inconvenience to pedestrians and vehicles, what's more, the phenomenon of irrigation will appear in the underground garages of some communities
