Description

Technical Field

[0001] The utility model relates to the technical field of rain and sewage wells, in particular to an assembled large-drop UHPC rain and sewage well. Background Technique

[0002] Rain and sewage wells, usually also known as inspection wells, are underground structures used to collect and discharge rainwater and sewage. For rainwater wells, the main function is to collect rainwater in areas such as roads and squares and guide it into the underground rainwater pipeline to prevent waterlogging on the road surface.

[0003] According to a concrete precast rain and sewage well disclosed in a Chinese patent with the publication number "CN215802147U", which includes a well wall, a fixing block is fixedly connected to the upper end of the well wall, a manhole cover is flange-connected to the upper end of the fixing block, a frame body is arranged in the middle of the well wall, a rotating shaft is rotatably connected to the middle of the frame body, the rotating shaft is respectively rotatably connected to the manhole cover and the fixing block, a first bevel gear is fixedly connected to the rotating shaft near the inner bottom end of the frame body, and a driving mechanism is arranged at the well wall near the frame body end. The utility model relates to the technical field of urban drainage. In this concrete precast rain and sewage well, when the water level is flush with the drain pipe, water flows into the drain pipe, and a first filter plate filters the dirt in the water flow. The filtered rainwater drives the impeller to rotate, and the impeller drives the second bevel gear and the turntable to rotate respectively. The second bevel gear drives the first bevel gear to rotate, and the first bevel gear drives the rotating rod to rotate through the rotating shaft. The brush at the end of the rotating rod cleans the dirt attached to the second filter plate to prevent blockage. Traditional rain and sewage wells are usually built by cast-in-place concrete, and the drop of the current municipal rain and sewage wells is only within a few meters. The short drop cannot effectively reduce the drainage time and is prone to water accumulation. Therefore, an assembled large-drop UHPC rain and sewage well is proposed to solve the above-mentioned problems. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide an assembled large-drop UHPC rain and sewage well for the deficiencies in the above-mentioned prior art.

[0005] To solve the above technical problem, the technical scheme adopted by the utility model is: an assembled large-drop UHPC rain and sewage well, including a standard-drop cylinder body, a cutting notch, a partition wall one, a positioning hole, a rotating step, an inflow cylinder body, a partition wall two, and an outflow cylinder body are arranged on the standard-drop cylinder body. The cutting notch is opened at the top ends of the inner walls of the standard-drop cylinder body, the inflow cylinder body, and the outflow cylinder body. The partition wall one is fixedly installed inside the standard-drop cylinder body. The positioning hole is opened at the top of the partition wall one, a positioning pin is installed inside the positioning hole. The rotating step is fixedly installed on one side of the partition wall one. The inflow cylinder body is installed on the top of the standard-drop cylinder body. The partition wall two is fixedly installed inside the inflow cylinder body. The outflow cylinder body is installed at the bottom of the standard-drop cylinder body.

[0006] Preferably, a ladder is also provided inside the inflow cylinder body, and the ladder is fixedly installed on the second partition wall. Through this preference, the inflow cylinder body can be fixedly installed on the top of the standard drop cylinder body.

[0007] Preferably, a first reserved hole is also opened on the inflow cylinder body, and an inflow pipe is installed at the first reserved hole. Through this preference, the inflow pipe is fixedly installed at the first reserved hole for inflow operation.

[0008] Preferably, a second reserved hole is also opened on the outflow cylinder body, and an outflow pipe is installed at the second reserved hole. Through this preference, the outflow pipe is fixedly installed at the second reserved hole for outflow operation.

[0009] Preferably, a cover plate is also fixedly installed on the top of the inflow cylinder body, and an inspection hole is opened on the cover plate. Through this preference, the cover plate is fixedly installed on the top of the inflow cylinder body to seal the inflow cylinder body.

[0010] Preferably, an inspection well is also provided on the top of the cover plate, and the inspection well is fixedly installed at the inspection hole. Through this preference, the inspection well is fixedly installed at the inspection hole opened on the cover plate, which can be used for personnel to enter the well for operation from the ground.

[0011] The present utility model adopts the above technical solutions and can bring the following beneficial effects:

[0012] 1. For this assembled large-drop UHPC rain and sewage well, by fixedly installing the outflow pipe at the second reserved hole for outflow operation, fixedly installing the standard drop cylinder body on the top of the outflow cylinder body, so that a specified number of standard drop cylinder bodies can be installed according to the actual installation specifications, fixedly installing the inflow pipe at the first reserved hole for inflow operation, and the internal rotating ladder in the standard drop cylinder body can be used for gravity drainage. The composed well can achieve a drop of dozens of meters. Specifically, the incoming water is guided along the rotating ladder to the outflow pipe, and the height difference between the inflow and outflow can be adjusted by increasing or decreasing the number of rotating ladder sections, thus achieving a large drop. The large drop can utilize the gravity effect to make the rain and sewage flow rapidly in the cylinder body, reduce the drainage time, and avoid the occurrence of water accumulation.

[0013] 2. For this assembled large-drop UHPC rain and sewage well, the standard drop cylinder body, the inflow cylinder body, and the outflow cylinder body all adopt UHPC materials, which have the characteristics of high strength, high toughness, and durability compared with ordinary concrete. Therefore, the rain and sewage well made of UHPC as the raw material can be used in various erosion environments, and has the ability of self-healing of concrete micro-cracks, and has advantages such as safer structure, higher impermeability, and higher durability than ordinary concrete rain and sewage wells.
