Description

Technical Field

[0001] This utility model relates to the field of building technology, specifically to a comprehensive pipe gallery structure with gravity-fed sewage inflow. Background Technology

[0002] For gravity-flow sewage inlets, there are various existing forms, mainly including independent compartments for gravity-flow sewage pipes or gravity-flow sewage pipes installed on the side of the municipal compartment. The following problems exist with the above two forms of gravity-flow sewage inlets: Separate compartments for gravity-flow sewage pipes: This will add a municipal compartment to the integrated utility tunnel, significantly increasing construction costs.

[0003] Gravity-flow sewage pipes are installed on the side of the municipal compartment: the applicability is poor, and it is difficult for sewage branch pipes in multi-compartment integrated utility tunnels to enter and exit the tunnel; for large-diameter sewage pipes entering the tunnel, the span of the municipal compartment structure will be further increased, which is detrimental to the structure of the integrated utility tunnel. Utility Model Content

[0004] The purpose of this utility model is to provide a comprehensive utility tunnel structure with gravity-flow sewage inflow to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A gravity-flow sewage inlet structure includes a municipal compartment, a gas compartment, sewage branch pipes, drop manholes, and a venting riser. The municipal compartment adopts a downward-facing convex-shaped cross-section structure, dividing the municipal compartment into an upper rectangular space and a lower rectangular space. The upper rectangular space is equipped with a municipal compartment maintenance passage, power pipelines, communication pipelines, water supply pipelines, and reclaimed water pipelines. The gravity-flow sewage main pipeline is located in the lower rectangular space below the municipal compartment maintenance passage. The gas compartment is independently located on the side of the municipal compartment for the installation of gas pipelines and a gas compartment maintenance passage. The sewage branch pipes are connected to the gravity-flow sewage main pipeline through the drop manholes. The gravity-flow sewage main pipeline is equipped with a socket-type single-branch tee. The bottom end of the venting riser is connected to the socket-type single-branch tee through a flange. The top end of the venting riser extends upward from the municipal compartment, passes through the ground, and extends into the road green belt.

[0006] Preferably, the drop well is provided with a gate slot for controlling the opening and closing of the drainage outlet.

[0007] Preferably, the top end of the ventilation riser is detachably covered with a pipe cover, and the pipe cover has several ventilation holes.

[0008] Preferably, the gravity-flow sewage main pipeline is made of ductile iron pipe specifically designed for sewage.

[0009] Preferably, the ventilation riser is made of steel-reinforced polyethylene composite pipe.

[0010] Preferably, the diameter of the ventilation riser is DN100.

[0011] By adopting the above technical solution, this utility model has the following advantages compared with the prior art: 1. This utility model provides a comprehensive utility tunnel structure for gravity-flow sewage inlet. The municipal compartment is divided into upper and lower rectangular spaces by a convex-shaped cross section. The gravity-flow sewage main pipe is set in the lower rectangular space and below the maintenance passage. The cross section of the municipal compartment is reused, avoiding the need for a new municipal compartment. This greatly improves the utilization rate of the cross section structure of the comprehensive utility tunnel, reduces construction costs, and the lower placement of the gravity-flow sewage main pipe reduces the span of the municipal compartment, improving structural stability.

[0012] 2. This utility model provides a comprehensive utility tunnel structure for gravity-flow sewage inflow. Impurities are collected in the sedimentation tank inside the drop well, and the gate slot controls the opening and closing of the drainage outlet, enabling independent maintenance of sewage branch pipes. This enhances applicability and effectively solves the problem of sewage branch pipes entering and exiting the comprehensive utility tunnel. Its applicability covers various scenarios of gravity-flow sewage inflow in comprehensive utility tunnels from single-compartment to multi-compartment. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0015] It should be noted that in this utility model, the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element of this utility model must have a specific orientation, and therefore should not be construed as a limitation of this utility model. Example

[0016] Please refer to Figure 1 and Figure 2As shown, this utility model discloses a comprehensive utility tunnel structure for gravity-flow sewage inflow, including a municipal compartment 1, a gas compartment 2, a sewage branch pipe 3, a drop manhole 4, and a ventilation riser 5. The municipal compartment 1 adopts a downward-facing irregular cross-section structure and is divided into an upper rectangular space 11 and a lower rectangular space 12. The upper rectangular space 11 is equipped with a municipal compartment maintenance passage 13, an electrical pipeline 14, a communication pipeline 15, a water supply pipeline 16, and a reclaimed water pipeline 17. The gravity-flow sewage main pipeline 6 is laid in the lower rectangular space 12 and below the municipal compartment maintenance passage 13. The gas compartment 2 is independently set on the side of the municipal compartment for laying a gas pipeline 21 and a gas compartment maintenance passage 22. The sewage branch pipe 3 is connected to the gravity-flow sewage main pipeline 6 through the drop manhole 4. The gravity-flow sewage main pipeline 6 is equipped with a socket single-branch tee 7. The bottom end of the ventilation riser 5 is connected to the socket single-branch tee 7 through a flange. The top end of the ventilation riser 5 extends upward from the municipal compartment 1 through the ground and extends to the road green belt.

[0017] The bottom of the drop well 4 is equipped with a sedimentation tank 41 to automatically collect impurities and reduce pipe blockage. The side wall of the drop well 41 and above the sedimentation tank 41 is equipped with a drain outlet 42 that is connected to the gravity flow sewage main pipe 6. The drop well 4 is equipped with a gate slot 43 to control the opening and closing of the drain outlet 42, which quickly intercepts sewage. The sewage branch pipe 3 can be repaired without shutting down the gravity flow sewage main pipe 6.

[0018] The ventilation riser 5 is fixed along the side wall of the pipe gallery, and PE special pipe clamps are installed at 2m intervals. The top end of the ventilation riser 5 is detachably covered with a pipe cover 51, which has several ventilation holes to prevent foreign objects from entering and avoid the risk of biogas accumulation and explosion.

[0019] The gravity-flow sewage main pipeline 6 uses ductile iron pipe specifically designed for sewage, improving sealing performance and preventing sewage from seeping into the municipal chamber. Its acid and alkali corrosion resistance and lifespan are more than three times that of ordinary concrete pipes. The main pipeline of the socket-type single-branch tee uses socket-type interfaces (socket + spigot) at both ends for direct insertion and sealing with ductile iron sewage pipes. The branch pipe interface has a flange structure (annular plane with bolt holes) for rigid connection to the vent riser flange via bolts. The tee body has a T-shaped diversion structure, with the main pipeline and branch pipe at a 90° angle, achieving connection between the main sewage pipe and the vent riser, solving the problem of sealing dissimilar materials. The flange connection supports quick disassembly, improving the maintenance efficiency of the vent riser.

[0020] Ventilation riser 5 is made of steel-reinforced polyethylene composite pipe. The diameter of the ventilation riser is DN100.

[0021] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of protection of this utility model. Therefore, the scope of protection of this utility model should be determined by the scope of the claims.
