Abstract
Description
Technical Field
[0001] The utility model relates to a negative pressure siphon system, especially to the field of domestic sewage collection and discharge. Background Art
[0002] The negative pressure siphon well mainly collects domestic sewage into the well first. A negative pressure siphon valve is installed in the negative pressure siphon well. When the sewage in the well reaches the set liquid level height, the siphon valve automatically opens, and the negative pressure siphon pipe network siphons the sewage in the well to the negative pressure station and then discharges it. When the sewage in the well reaches the low liquid level, the siphon valve closes and the sewage in the well stops discharging.
[0003] The negative pressure siphon well is often buried underground. Although the soil is solid, the negative pressure siphon well is deeply buried underground, and the soil below is subjected to the upward acting force of the surrounding soil pressure, which acts on the siphon well and causes the siphon well to float. Summary of the Utility Model
[0004] The utility model is committed to solving the above technical defects, and provides a negative pressure siphon well. The negative pressure siphon well structure is integrally formed, and its manhole cover, interface and well body are all formed at one time to ensure that there are no problems such as water leakage in the well. Through the design of the reinforcing rib structure on the outside and bottom of the negative pressure siphon well, it is ensured that the negative pressure siphon well does not have problems such as dislocation and displacement, and the stable operation of the negative pressure siphon valve is guaranteed. By providing a concave groove part and a supporting partition board between the interfaces, the negative pressure siphon well can be divided into a lower sewage collection area and an upper maintenance area, which is convenient for later maintenance and solves the problem of difficult sealing of the split type.
[0005] The technical solution adopted by the utility model is: a negative pressure siphon well, including an integrally formed siphon well, the outer wall of the siphon well is convexly provided with transverse ribs, and the outer wall of the siphon well is convexly provided with longitudinal reinforcing ribs. The setting of the transverse reinforcing ribs can help to restrain the upward floating effect of the soil after deep burial and prevent floating in the deep soil.
[0006] Preferably, the longitudinal reinforcing ribs and the transverse reinforcing ribs are arranged in an intersecting connection. The intersecting longitudinal reinforcing ribs and transverse reinforcing ribs disperse the internal pressure-bearing capacity and contribute to the overall compressive resistance.
[0007] Preferably, at least one interface for connecting pipelines is provided at the upper end of the siphon well, and the opening of the interface is closed and opened through when connecting pipelines is needed.
[0008] Preferably, the siphon well includes a wide upper part and a narrow lower part, and the interface is arranged on the wide part.
[0009] Preferably, a concave groove part is provided between the interfaces, and both the upper end and the lower end of the concave groove part exceed the interface part.
[0010] Preferably, the concave groove part forms a step for installing a partition board inside the siphon well.
[0011] Preferably, reinforcing ribs are provided at the bottom of the siphon well.
[0012] Preferably, the interfaces are evenly distributed around the siphon well.
[0013] Preferably, the siphon well is integrally formed with a well cover, which can be buckled onto the siphon well.
[0014] The beneficial effects of the utility model are:
[0015] 1. The utility model adopts an integrated negative pressure siphon well structure, and its negative pressure siphon well cover, interface and well body are all formed at one time, ensuring that the well will not leak;
[0016] 2. The longitudinal reinforcement ribs and transverse reinforcement ribs on the outside of the negative pressure siphon well are staggered and connected to enhance the pressure resistance and buoyancy resistance of the negative pressure siphon well after it is buried, so as to avoid deformation of the negative pressure siphon well after it is buried and affect the siphon effect;
[0017] 3. The design of the bottom reinforcement ribs can ensure the flatness of the bottom of the negative pressure siphon well, reduce the risk of deformation, ensure that the negative pressure siphon well does not have problems such as dislocation and displacement, and ensure the stable operation of the negative pressure siphon valve in the negative pressure siphon well.
[0018] 4. The concave groove and matching partitions between the interfaces can be used to divide the negative pressure siphon well into a lower sewage collection area and an upper maintenance area, which is convenient for later maintenance and solves the problem of split-type sealing difficulties. The lower sewage collection area can be installed with a negative pressure siphon valve group; the upper maintenance area is used to install negative pressure pipes, pipe fittings and negative pressure gauges, and is also a maintenance channel for negative pressure pipes and negative pressure siphon valves.
[0019] 5. A manhole cover is integrally formed with the siphon well, and the manhole cover can be buckled on the siphon well to prevent rainwater and debris from entering the negative pressure siphon well. BRIEF DESCRIPTION OF THE DRAWINGS
