Abstract
Description
Technical Field
[0001] The utility model relates to the field of construction, and particularly relates to a drainage pipeline system with a blockage prevention monitoring device. Background Technique
[0002] In multi-story or high-rise buildings, when the building drainage pipeline is converted or exits the building, the pipeline changes from vertical to horizontal. In the horizontal pipeline section, the water flow velocity decreases, and suspended solids or solid substances in the water flow are extremely likely to deposit, resulting in pipeline blockage. If the pipeline blockage cannot be detected in time, it will bring great troubles to people's life and work and may cause property losses. If it cannot be dredged in time, it will cause great troubles to property maintenance in the later stage and increase the maintenance and dredging costs.
[0003] There are horizontal pipelines in the building drainage pipeline at two positions: 1. The equipment pipeline conversion layer. Some equipment pipeline conversion layers or podium conversion layers in the middle floors of the building, and more are the first-floor overhead layers. For residential buildings, the proportion of drainage pipeline conversion in the ceiling of the first-floor overhead layer is relatively high. 2. Horizontally laid and exiting the building below the building's ±0 slab on the first floor (lowered slab covered with soil or under the slab or the ceiling of the first basement floor).
[0004] Although the horizontally laid drainage pipeline has a certain slope, various suspended solids or solids in the drainage pipeline are still extremely likely to deposit in the horizontal pipeline. The following reasons for blockage are more common: 1. Construction waste entering the drainage pipeline during the construction process. 2. Waste water containing oil and vegetable residues such as kitchen drainage. 3. Hair and various sundries entering the drainage pipeline.
[0005] If the conversion layer drainage pipeline and the first-floor outlet drainage pipeline are blocked, the floors connected to the drainage main pipe at the bottom are directly affected first, such as the residents on the first floor or the residents above the overhead conversion layer. Although the national code stipulates the connection methods and requirements for drainage of relevant floors and the drainage main pipe, this regulation is a requirement for the water flow and air flow conditions in the pipeline. When the pipeline is blocked, it will first overflow to the relevant bottom floors, affecting the lives of the residents on these floors.
[0006] In recent years, blockages in the outlet pipe or the conversion pipe of the conversion layer have become more and more common. Designers have adopted the design of separately discharging the drainage pipeline on the first floor or the upper floor of the conversion layer, avoiding the impact on the bottom floors due to pipeline blockage. However, if a blockage really occurs and cannot be detected and dredged in time, the lowest-level pipeline connected to the drainage main pipe will still be affected first. Currently, the design of separately discharging the drainage on the bottom floors cannot completely solve the problem. Utility Model Content
[0007] Aiming at the above problems, the utility model aims to provide a drainage pipeline system with a blockage prevention monitoring device, which is convenient for timely dredging when a blockage is found.

[0014] Preferably, it also includes a second-layer single-row pipe installed on the second floor of the building, the highest point of the second-layer single-row pipe is higher than the starting highest point of the horizontal main pipe, and a ventilation pipe is also arranged between the second-layer single-row pipe, the drainage pipe and the horizontal main pipe.
[0015] Preferably, the drainage pipe and the lower part of the two-layer single-row pipe are both provided with a water stop valve.

[0022] The following further elaborates on the utility model of the present application in detail in conjunction with the accompanying drawings and specific embodiments. For a clear and complete description of the technical solution, the following embodiments are selected for illustration; based on the content recorded in the present application, other embodiments obtained without creative labor fall within the protection scope of the present utility model.
[0023] In the following embodiments, it should be noted that the orientation or positional relationships such as "upper", "lower", "left", "right", "inner", "outer", "top / bottom", etc. in the terms are all based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of clearly describing the present embodiment, rather than indicating or implying that the device or element referred to must have a specific orientation, so it cannot be understood as a limitation to the present application.
[0024] Such as Figures 1-3As shown, the specific embodiment described in the utility model is a drainage pipe 1 system with an anti-blocking monitoring device, including two or more drainage pipes 1 installed between floors for sewage or wastewater discharge. In order to meet the requirements of multi-story buildings, an anti-blocking monitoring mechanism is set on one side of the drainage pipe 1 to monitor in real time whether the drainage pipe 1 is blocked and provide a warning when blocked. The anti-blocking monitoring mechanism consists of a drainage branch pipe 2, a valve 3, an outlet pipe 4 and a water trap 5. The drainage branch pipe 2 is located on one side of the drainage pipe 1. The drainage pipe 1 is connected to the drainage branch pipe 2 through a water-following tee (a Y-shaped structure). The valve 3 is located in the middle of the drainage branch pipe 2. The valve 3 is used to control the water flow of the drainage branch pipe 2. The valve 3 preferably adopts a plastic ball valve in a normally open state. When sewage overflow is found, the valve 3 is closed to carry out dredging and emergency repair. The two ends of the water trap 5 are connected to the outlet pipe 4 and the drainage branch pipe 2 respectively. The outlet pipe 4 is located lower than the lowest position of the water trap 5. The water trap 5 is used to isolate odor and odor, prevent the malodorous gas in the sewage from entering the room through the drainage branch pipe 2, and keep the indoor environment fresh. The outlet pipe 4. The drainage branch pipe 2 is also provided with an inspection port 201 that can replenish water for the water trap 5. In the early stage of the project completion, water is replenished through the inspection port 201, and the water trap contains no less than 50mm of water to avoid the overflow of odor in the sewage pipe under normal conditions. When the water trap 5 dries up during use (judged by the overflow of odor), the property needs to open the inspection port 201 for replenishment. A film seal can also be used at the outlet pipe 4, and the seal can automatically fall off when sewage overflows.
[0025] The drainage branch pipe 2 is a UPVC water supply pipe structure. UPVC is made of rigid polyvinyl chloride, a lightweight, corrosion-resistant plastic pipe with a smooth inner wall. It is very suitable for drainage systems. The diameters of the drainage branch pipe 2, the outlet pipe 4 and the water trap 5 are all 50 mm, which can handle an appropriate amount of sewage and wastewater flow to ensure smooth water flow; the height of the water stored in the water trap 5 is greater than 50 mm, ensuring that there is always enough water in the water trap 5 to form a water seal to prevent the foul smell in the sewage from entering the room through the drainage branch pipe 2. A sewage outlet 501 is provided at the bottom of the water trap 5 to facilitate the cleaning of sediments and maintain smoothness.
[0026] The distance between the drainage branch pipe 2 and the drainage pipe 1 and the ground is greater than or equal to 300 mm, which is convenient for maintenance and inspection.
[0027] In order to ensure that sewage can flow smoothly into the drainage pipe 1, the middle section of the drainage branch pipe 2 is higher than the connection between the drainage branch pipe 2 and the drainage pipe 1, so as to avoid the sewage not being able to flow smoothly and the water backflow due to the drainage branch pipe 2 being lower than the drainage pipe 1, thereby ensuring the smooth operation of the drainage system.
[0028] When the drainage system needs to be turned or diverted, a horizontal main pipe 101 can be set in the middle of the drainage pipe 1 to help the wastewater flow smoothly into the cross-section and then flow into the next-level drainage pipe 1. In order to prevent the wastewater from flowing back, the connection between the drainage branch pipe 2 and the drainage pipe 1 is higher than the starting highest point of the horizontal main pipe 101.
[0029] In order to increase the drainage capacity, a two-layer single-row pipe 7 is installed on the second floor. The highest point of the two-layer single-row pipe 7 is higher than the starting highest point of the horizontal main pipe 101, which is conducive to the smooth flow of wastewater into the horizontal main pipe 101 and avoids backflow. A ventilation pipe 8 is also arranged between the two-layer single-row pipe 7, the drainage pipe 1 and the horizontal main pipe 101 to discharge harmful gases in the drainage pipe 1.
[0030] A water stop valve 6 is provided at the bottom of the drainage pipe 1 and the two-layer single-row pipe 7, which can quickly cut off the water source when an emergency such as a failure occurs in the drainage pipe 1 or the two-layer single-row pipe 7.
[0031] For the convenience of observation, a transparent observation window for detecting blockage is provided at the end of the drainage branch pipe 2, through which it can be checked whether the sewage is blocked.
[0032] This monitoring device is installed on the drainage branch pipe 2 on the drainage pipe 1, and is higher than the starting highest point of the horizontal main pipe 101. When the horizontal main pipe 101 is blocked, the water level of the pipe will slowly overflow to the pipe port of the anti-blocking monitoring mechanism, and overflow to the ground through the anti-blocking monitoring mechanism. After the property inspection is discovered, the valve 3 can be closed first, and then the horizontal main pipe can be dredged in time.
[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any minor modifications, equivalent substitutions and improvements made to the above embodiments based on the technical essence of the present invention should be included in the protection scope of the technical solution of the present invention.
