Foundation Inspection Well: The Foundation Inspection Well is used to inspect the foundation structure of buildings, primarily to ensure that the foundation meets the regulatory requirements and can bear the weight and loads of the structure.

Precast Reinforced Concrete Manhole Frames: Precast reinforced concrete manhole frames are prefabricated components designed to support and secure the load-bearing portion of the manhole cover. Their primary function is to bear the loads from vehicle traffic, pedestrian movement, etc., ensuring the safety and reliability of the manhole cover.

Catchment Well: A catchment well is used for wastewater interception and treatment, primarily for pre-treating wastewater, separating solid waste from liquid waste, and then discharging the wastewater into the sewage system or treatment plant for further processing, to protect the environment.

Municipal Stormwater Inlets: These inlets are designed for stormwater drainage and collection, primarily to gather rainfall within urban areas, prevent flooding, and ensure the smooth operation of the city's drainage system. Additionally, proper management and maintenance of stormwater inlets contribute to beautifying the city environment, purifying the air, and reducing smog.
