Description

Technical Field

[0001] The present invention relates to the technical field of urban drainage structures, in particular to an assembled drop well prefabricated component. Background Art

[0002] As one of the important facilities for controlling the construction process of sponge cities, drop wells can effectively solve the damage to the drainage system caused by the gravitational potential energy of water due to the large drop in drainage pipes during the construction of urban drainage networks.

[0003] Traditional waterfalls are constructed using cast-in-place reinforced concrete, which results in long construction cycles, high levels of pollution, and high noise levels. With prefabricated waterfalls, prefabricated components can be mass-produced in factories, significantly reducing the use of formwork, steel pipes, and scaffolding. Furthermore, the production equipment and molds for prefabricated components can be reused, reducing consumables, conserving resources, and improving the overall quality and performance of the building. This can also reduce air pollution caused by the construction process, water pollution caused by construction waste, and noise pollution, minimizing interference with the surrounding environment. This is beneficial for protecting the ecological environment and promoting the development of an ecological civilization. Therefore, how to manufacture prefabricated components for prefabricated waterfalls has become a technical problem that those skilled in the art urgently need to solve. Summary of the Invention

[0009] The manhole cover is located on the ground and at the top of the manhole to prevent people or objects from falling. It also serves as a carrier for ventilation between the inside of the manhole and the outside world.

[0010] The ground is the surface, which is located above the plunge well, and the plunge well cover is located here.

[0011] Preferably, the well wall of the drop member includes a lower inner wall of the drop member, a lower outer wall of the drop member, an upper inner wall of the drop member, an upper outer wall of the drop member and a cavity of the drop member;

[0012] The lower inner wall of the drop component and the lower outer wall of the drop component are both located at the lower part of the well wall of the drop component and are used for connecting different components;

[0014] Preferably, the baffle body includes a baffle body cavity and a baffle body side wall, wherein the baffle body side wall is located on both sides or one side of the lower portion of the baffle body and together with the baffle body forms the baffle body cavity;

[0015] The cavity of the drop component is formed by removing the baffle, the baffle cavity, the vent pipe and corresponding components from the well wall of the drop component and is used for ventilation.

[0016] Preferably, the vent pipe includes a lower pipe wall of the vent pipe, a vent, a vent pipe cavity and a vent pipe cap. The lower pipe wall of the vent pipe is located at the lower part of the vent pipe, and has a right-angled flare for ventilation. The vent is located on the side wall of the vent pipe, and is externally connected to the baffle body, the baffle body side wall and the baffle body cavity. The cross-sectional area of ​​the vent is smaller than the cross-sectional area of ​​the baffle body cavity. The upper part and the side of the vent are flush with the upper part and the side of the baffle body cavity. The lower part of the vent is higher than the lower part of the baffle body cavity to prevent rainwater or sewage from generating wall flow back into the vent pipe. The vent pipe cavity is located inside the vent pipe for ventilation. The vent pipe cap is located above the vent pipe of the plunge well. The upper part of the vent pipe cap is hemispherical, the middle part is hollowed out, and the side wall is provided with a plurality of holes for ventilation.

[0017] Preferably, the side wall of the lower component of the drop well is connected to a drop well outlet pipe, and stones are provided at the lower part of the lower component of the drop well; the drop well outlet pipe is used to discharge rainwater or sewage, so that sewage or rainwater is discharged from the inside of the drop well and is connected to the lower component of the drop well; the stones prevent rainwater or sewage from washing the bottom of the lower component of the drop well.

[0021] The beneficial effects of the present invention are:

[0022] 1. The internal baffles are staggered to prevent rainwater or sewage from falling directly into the lower component of the drop well through the cavity of the drop component without dissipating energy through the baffle. When rainwater or sewage enters the drop well from the water inlet pipe and falls, the baffle on the drop component will block the normal fall of the water flow, causing the water flow direction to change continuously, thereby buffering the potential energy and kinetic energy of the water flow and reducing the scouring of the drop well.

[0023] 2. After energy dissipation, the water flows into the lower component of the drop well and is discharged through the drop well outlet pipe. At the same time, the baffle cavity on the prefabricated drop component is connected to the vent pipe through the vent, achieving the ventilation function, allowing air circulation in the drop well and stabilizing the pressure. In addition, the connection between the vent pipes in the two drop components can also achieve the purpose of ventilation.

[0024] The use of the assembled prefabricated components of the present invention can shorten the construction period of the drop well and the drainage network; facilitate transportation and hoisting; solve the structural stability and anti-seepage problems of each component; and solve the air pressure balance in the assembled drop well.
