Description

Technical Field

[0001] The utility model belongs to the technical field of municipal drainage engineering, and in particular relates to a long-distance inverted siphon hydraulic self-flushing structure facility. Background Art

[0002] The inverted siphon is a commonly used drainage method in municipal sewage pipe systems, where the pipes cross obstacles such as rivers, dry ditches, depressions or underground structures. When the sewage pipe conflicts with the above obstacles in elevation, it is necessary to pass under the obstacles. In order to avoid the downstream pipe being buried too deep, the inverted siphon facility has appeared. In recent years, with the increase in urban population, the capacity of urban underground sewage pipes has gradually expanded and increased, and the areas and fields of application of inverted siphon pipes have also gradually increased, and the distance of inverted siphons, the depth of inverted siphon wells, and the flow capacity of inverted siphons have also gradually increased. Since there are many impurities and silt in the sewage pipes themselves, when passing through the inverted siphon, most of the sediments gradually accumulate in the inverted siphon, which causes the inverted siphon pipe to be blocked, causing upstream sewage overflow pollution.

[0003] At present, in order to solve the siltation problem in the inverted siphon, there are two common methods in design: one is to install a small-diameter hose in the inverted siphon and connect high-pressure water to regularly flush the inside of it, and the other is to install a barrier shield device inside the inverted siphon well for regular water storage and flushing. After analysis and practical investigation, these two methods are currently suitable for flushing inverted siphons with shorter distances and shallower depths. For flushing inverted siphons with longer distances and greater depths, their effects and practicality are difficult to meet. After being blocked, they can only be dredged and cleaned by manual and mechanical equipment, which is time-consuming, labor-intensive, and costly, and requires regular cleaning by special personnel, which affects the operation and discharge capacity of the sewage pipe network. Therefore, it is urgent to improve the hydraulic self-flushing technology of long-distance inverted siphons. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide a long-distance inverted siphon hydraulic self-flushing structure facility to solve the deficiencies in the prior art.

[0005] In order to achieve the above object, the utility model is implemented by the following technical solutions:

[0006] Provided is a long-distance inverted siphon hydraulic self-flushing structure facility, comprising an inlet inverted siphon well, an outlet inverted siphon well, an inverted siphon pipeline, an inlet pipeline and an outlet pipeline, wherein the inlet inverted siphon well and the outlet inverted siphon well are connected via the inverted siphon pipeline;

[0007] The water inlet inverted siphon well is divided into a sedimentation transfer room, a water inlet room, a flushing water tank room, a water inlet post-maintenance room and a water inlet operation room. The flushing water tank room, the water inlet room and the water inlet post-maintenance room are arranged horizontally in sequence. The sedimentation transfer room is located at the top of the flushing water tank room and is adjacent to the water inlet room. The water inlet pipe is connected to the sedimentation transfer room. A first gate is provided between the sedimentation transfer room and the water inlet room. A second gate is provided between the flushing water tank room and the water inlet room. One end of the inverted siphon pipe is arranged at the bottom of the water inlet post-maintenance room. A third gate is provided at one end of the inverted siphon pipe facing the water inlet room. A water inlet operation system for controlling the first gate, the second gate and the third gate is provided in the water inlet operation room.

[0008] The water outlet inverted siphon well is divided into a regulating and transferring room, a water outlet room, a cleaning and pumping room, a water outlet post-maintenance room and a water outlet operation room. The cleaning and pumping room, the water outlet room and the water outlet post-maintenance room are arranged horizontally in sequence. The regulating and transferring room is located at the top of the cleaning and pumping room and is adjacent to the water outlet room. The water outlet pipe is connected to the regulating and transferring room. A fourth gate is provided between the cleaning and pumping room and the water outlet room. A fifth gate is provided between the regulating and transferring room and the water outlet room. The other end of the inverted siphon pipe is arranged at the bottom of the water outlet post-maintenance room. A water outlet operating system for controlling the fourth gate and the fifth gate is provided in the water outlet operation room.

[0009] As in the long-distance inverted siphon hydraulic self-flushing construction facility, an inclined flow trough is provided at the bottom of the flushing water tank room.

[0010] For example, in the long-distance inverted siphon hydraulic self-flushing structure facility, the water inlet operating system and the water outlet operating system can both realize on-site or remote control and rapid opening and closing of each gate.

[0011] As for the long-distance inverted siphon hydraulic self-flushing structural facility, the water inlet room and the water outlet room are both juxtaposed double-room structures.

[0012] The beneficial effects of the technical solution of the utility model are:

[0013] By utilizing its own structure and water source, storing water in the water tank room and controlling the gates on-site or remotely, regular hydraulic self-flushing of deeper inverted siphons and long-distance inverted siphons is achieved. The flushing effect is good, and alternating operation does not affect normal water flow. Compared with other flushing methods, it is more convenient, reliable, economical and efficient, and saves manpower and operating costs. BRIEF DESCRIPTION OF THE DRAWINGS
