A stormwater drywell system is provided that filters water to a predetermined standard prior to depositing the water in the ground. The drywell system can have a primary settling chamber that screens the water in a first instance prior to transmitting the water to a drywell chamber. The drywell chamber can have one or more filters arranged in a modified manhole base where each filter is positioned over an aperture. Within the aperture is an orifice constructed and sized, in some embodiments, to limit the flowrate of water through the orifice and through the respective filter. This ensures a sufficient residence time of water in the filter to filter pollutants out of the water to the predetermined standard. Moreover, flow is limited to only these filters, apertures, and orifices without any bypass to ensure that only sufficiently filtered water is deposited in the ground.

This invention relates to a drainage well system for a foundation pit suitable for a ground-mounted waterproof curtain. The system includes a drainage well body positioned within the backfill area of ​​the foundation pit, located between the main structural wall and the ground-mounted waterproof curtain. The drainage well bodies are arranged at predetermined intervals within the backfill area. The outer facade of the main structural wall is provided with a waterproof layer. Each drainage well body includes a non-porous solid pipe section and a perforated filter section located below the non-porous solid pipe section. The perforated filter section is externally covered with a filter layer, and the surrounding hollow spaces of the filter layer are filled with graded filter media. The lower end of the drainage well body is positioned below the bottom of the foundation pit and above the stable waterproof layer. A pumping system is installed within the drainage well body to promptly pump out seepage water from the foundation pit when the water level within the drainage well body rises to a preset level. The pumping system is connected to the municipal stormwater drainage network. This invention can serve as a long-term drainage facility and also enables water resource reuse.

The application discloses an auxiliary system for dry well furnace metering detection, and belongs to the technical field of instrument analysis and instrument measurement technology. The auxiliary system comprises an oil film self-adding test cavity and an oil infiltration device. The oil film self-adding test cavity and the oil infiltration device are located in the soaking block of the dry well furnace. The oil infiltration device comprises a sealing bead, a compression spring, an oil guide pipe and an oil injector. When a temperature probe is inserted into the oil film self-adding test cavity through the top receiving port, the temperature probe extrudes the sealing bead to compress the compression spring, so that the oil infiltration device performs an oil infiltration action. At this time, the heat conducting oil in the oil injector seeps out from the gap between the sealing bead and the oil guide pipe through the oil guide pipe. The heat conducting oil infiltrates the inner wall of the oil film self-adding test cavity through the spiral oil guide groove, so that an oil film is formed between the temperature probe and the inner wall of the oil film self-adding test cavity. The application realizes sufficient contact and heat conduction by forming the oil film, thereby effectively reducing the metering detection error.
