Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of interception wells, in particular to a sewage interception well. Background Art
[0002] Sewage interception wells are facilities used to control and collect sewage in municipal drainage systems. Sewage interception wells intercept sewage in the dry season to prevent it from being discharged directly into water bodies. In the rainy season, they control the introduction of large amounts of rainwater into rivers, reducing drainage pressure. At the same time, they prevent sewage from entering rivers during the dry season, reducing pollution to water bodies.
[0003] The sewage interception well is built by setting up a height difference between the sewage pipe and the overflow pipe. During the rainy season, the water volume is large and the sewage pipe cannot be discharged in time. The accumulated rainwater accumulates in the cistern and rises into the overflow pipe. The overflow pipe then leads the rainwater into the river, avoiding the normal situation where sewage enters the river. The water in the cistern needs time to accumulate. During the short-term rainstorms in the rainy season, the rainwater enters the sewage pipe. The time is short and the rainwater accumulation is insufficient, resulting in less rainwater flowing to the overflow pipe, and low flood diversion and drainage efficiency of the sewage pipe network in precipitation. Summary of the invention
[0004] The disclosed embodiment relates to a sewage intercepting well, in which sewage in a water inlet pipe is discharged from a lower water outlet into the sewage pipe. When the rainy season comes, rainwater will fill the water inlet pipe, and part of the water in the water in the water inlet pipe will enter the rainy season extension pipe. Sand and gravel in the water will be retained by the lower intercepting plate to prevent the sand and gravel from remaining in the rainy season extension pipe and causing the rainy season extension pipe to be stuck by the sand and gravel. The rainwater impacts the tail baffle to drive the rainy season extension pipe to move away from the water inlet pipe, and the rainy season extension pipe moves between the baffle plate and the overflow pipe, quickly draining a large amount of rainwater to the overflow pipe, thereby improving the discharge efficiency of rainwater.

[0011] In at least some embodiments, the rainy season extension pipe moves toward one side of the overflow pipe, and the tail end of the rainy season extension pipe moves above the water baffle.

[0032] In the disclosed embodiment, the lower water outlet 201 is located above the lower drainage trough 103, and the lower intercepting plate 202 is located on the side of the lower water outlet 201 along the flow direction of the water. The width of the lower intercepting plate 202 is wider than the lower water outlet 201. The sand and gravel in the bottom water are retained by the lower intercepting plate 202. The lower intercepting plate 202 blocks the sewage to prevent the sewage from continuing to flow toward the rainy season extension pipe 3. When the rainy season extension pipe 3 is contracted, the tail end of the rainy season extension pipe 3 is above the lower drainage trough 103, and the sewage entering the rainy season extension pipe 3 will also flow out to the lower drainage trough 103.
[0033] In the disclosed embodiment, the rainy season extension pipe 3 moves toward the side of the overflow pipe 101, and the tail end of the rainy season extension pipe 3 moves above the water baffle 104. The tail end of the rainy season extension pipe 3 quickly drains a large amount of rainwater to the overflow pipe 101, and the overflow pipe 101 is discharged into the river, thereby improving the discharge efficiency of rainwater. The rear baffle ring 301 moves to the inner side of the lower water outlet 201, and the rear baffle ring 301 blocks a part of the lower water outlet 201, thereby reducing the diversion of water flow at the lower water outlet 201 and increasing the impact force of the water flow on the tail baffle 305.
[0034] Embodiment 2, on the basis of embodiment 1, the rainy season extension pipe 3 and the water inlet pipe 2 are fixedly connected, the tail end of the rainy season extension pipe 3 is extended to between the water retaining plate 104 and the overflow pipe 101, the height of the lower intercepting plate 202 is increased to one-half the height of the water inlet pipe 2, the rainy season water flow increases and overflows the lower intercepting plate 202 into the rainy season extension pipe 3, and then is introduced into the overflow pipe 101, compared with the water flow gathering in the lower drainage groove 103, it can be drained more quickly, and at the same time, the situation of the rainy season extension pipe 3 sliding and getting stuck is avoided, and the setting of the upper slide bar 302, the external connecting pipe 303, and the internal support spring 304 is also avoided, thereby reducing the number of components and reducing the manufacturing difficulty.
[0035] The working principle of this embodiment is as follows: the main intercepting well body 1 can be made of glass fiber reinforced plastic and prefabricated in the factory and then pre-buried on site. The overflow pipe 101 is connected to the pipe that discharges into the river. The sewage pipe 102 is connected to the downstream municipal sewage pipe. The water inlet pipe 2 is connected to the upstream municipal sewage pipe. The sewage in the water inlet pipe 2 is discharged from the lower outlet 201 to the lower drainage trough 103. The lower drainage trough 103 is a funnel-shaped structure that guides the sewage into the sewage pipe 102. The sewage pipe 102 is below the overflow pipe 101. When the rainy season comes, a large amount of The rainwater will fill the water inlet pipe 2, and the rainwater will overflow the lower intercepting plate 202. The lower water outlet 201 cannot meet the drainage scale in the rainy season. Most of the water in the water inlet pipe 2 enters the rainy season extension pipe 3. The sand and gravel in the bottom water are retained by the lower intercepting plate 202. The lower water outlet 201 diverts the sand and gravel in the bottom to the lower drainage trough 103. The gap between the tail baffle 305 and the lower part of the rainy season extension pipe 3 discharges water flow while flushing away the silt, so as to avoid the sand and gravel remaining on the inner side of the rainy season extension pipe 3, causing the rainy season extension pipe 3 to be stuck by sand and gravel.
[0036] A large amount of rainwater enters the rainy season extension pipe 3 and impacts the tail baffle 305 at the tail end of the rainy season extension pipe 3. The rainwater impacts the tail baffle 305 and the rainy season extension pipe 3 and moves away from the water inlet pipe 2. The tail end of the rainy season extension pipe 3 moves between the water retaining plate 104 and the overflow pipe 101. The tail end of the rainy season extension pipe 3 quickly drains a large amount of rainwater to the overflow pipe 101, and the overflow pipe 101 is discharged into the river, thereby improving the discharge efficiency of rainwater and avoiding the situation where rainwater accumulates in the lower drainage trough 103 and overflows the water retaining plate 104. In the short-term heavy rain with large flow in the rainy season, the tail end of the rainy season extension pipe 3 quickly drains a large amount of rainwater to the overflow pipe 101, thereby better adapting to the sudden heavy rain weather in the rainy season.
[0037] The rainy season extension pipe 3 and the rear baffle ring 301 move synchronously, the upper slide bar 302 moves synchronously and compresses the inner support spring 304, the rear baffle ring 301 blocks a part of the lower water outlet 201, reduces the diversion of the water flow at the lower water outlet 201, and increases the impact force of the water flow on the tail baffle 305. When the water flow is reduced, the inner support spring 304 supports the upper slide bar 302 to slide toward the inside of the outer connecting pipe 303, the upper slide bar 302, the rainy season extension pipe 3 and the rear baffle ring 301 move synchronously and reset, the rear baffle ring 301 no longer blocks the lower water outlet 201, and the sewage continues to enter the lower drainage trough 103 and the sewage pipe 102 from the lower water outlet 201, preventing the sewage from entering the polluted river along the overflow pipe 101.
