[0002] As an advanced municipal infrastructure, the urban underground comprehensive pipeline corridor has effectively solved the problems of urban spider webs and road zippers. Localities have actively explored practical experience and achieved "construction according to needs", making the construction of pipeline corridors more scientific and targeted, and building small comprehensive pipeline corridors to enrich the layout of urban comprehensive pipeline corridor construction. Small comprehensive pipeline corridors are generally set up under the sidewalk or green belt, and are constructed in a shallow buried trench method. They are used to accommodate pipelines such as medium and low voltage power cables, communication cables, and small diameter pressure pipelines. The shallow buried trench is equipped with an openable cover for pipeline access and laying. The internal space does not need to consider the normal passage requirements of personnel, and does not have ventilation, fire protection, monitoring and other ancillary facilities.
[0003] The inventors found that since small pipe corridors are buried underground, water is easily accumulated in the corridors. The water mainly comes from water seepage at the cover plate, water leakage at the outlet, water seepage at the deformation joints, and water seepage at the inspection port, etc. Since small integrated pipe corridors do not meet the requirements for normal personnel passage, no drainage facilities are set up, but water accumulation in the corridors can easily cause pipeline corrosion, reducing the service life of pipelines and brackets.

[0028] It should be noted that the following detailed descriptions are all illustrative and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.
[0029] Embodiment 1
[0030] In a typical implementation of the present invention, reference is made to Figure 1 As shown, a small integrated pipe gallery drainage system includes a small integrated pipe gallery 19 and a drainage well 23 arranged on one side of the small integrated pipe gallery. The bottom of the small integrated pipe gallery 19 is connected to the drainage well 23 through a drainage hole 11. A submersible sewage pump 1 is arranged in the drainage well 23. The accumulated water in the small integrated pipe gallery 19 is discharged into the drainage well 23 through the drainage hole 11, and the accumulated water is discharged into a nearby rainwater well or rainwater outlet through the submersible sewage pump 1.
[0031] like Figure 1 and Figure 2As shown, the drainage system of the small integrated pipe gallery includes two structures, one is the small integrated pipe gallery 19, and the other is the drainage well 23. Among them, the small integrated pipe gallery 19 is laid under the sidewalk 21 or the green belt, and the clear height of the pipe gallery is less than 2m, which does not meet the requirements for normal passage of personnel. The pipe gallery is supported by brackets to support pipelines such as medium and low voltage power cables, communication cables, and small diameter pressure pipelines.
[0032] The standard soil cover of the small integrated pipe gallery 19 is less than 50 cm, which meets the paving requirements and planting requirements of the sidewalk tiles 21, and the top plate of the small integrated pipe gallery 19 adopts a cover plate 18 with a width of 1.0 m, which will be covered after the installation of the pipelines in the gallery is completed.
[0033] A 0.5% drainage slope 13 is set on the bottom plate of the small integrated pipe gallery 19, a 30x20cm drainage hole 11 is set at the bottom of the side wall, and an open drainage ditch 12 is set at the end of the drainage slope 13. The open drainage ditch 12 is set inside the drainage hole 11. The accumulated water in the gallery is collected into the open drainage ditch 12 through the drainage slope 13, and the water in the open drainage ditch 12 is discharged into the drainage well 23 through the drainage hole 11 at the low point of the pipe gallery. A check valve 17 is installed at the drainage hole 11 to prevent the accumulated water from flowing back.
[0034] like Figure 2 As shown, the drainage well 23 is arranged on one side of the small integrated pipe gallery 19, and a steel grating cover plate 9 is horizontally arranged inside the drainage well 23. The steel grating cover plate 9 divides the drainage well 23 into two upper and lower spaces. The upper space is used for maintenance by staff, and the lower space forms a water collection tank 20.
[0035] The water collecting tank 20 is connected to the drainage hole, and the elevation of the water collecting tank 20 is lower than the height of the drainage hole 11. A submersible sewage pump 1 is arranged inside the water collecting tank 20. The outlet pipe of the submersible sewage pump 1 extends to the top of the steel grille cover plate 9 and extends from the side wall of the drainage well 23 to the outside, and the water in the water collecting tank is discharged through the submersible sewage pump 1.
[0036] Specifically, a power line hole 16 is provided on the side wall of the small integrated pipe gallery, which is used to set a φ80mm power line pipe to facilitate power supply to the submersible sewage pump 1. A float liquid level switch 22 is provided inside the water collection tank, and the float liquid level switch 22 is electrically connected to the submersible sewage pump 1. The submersible sewage pump 1 is automatically started and stopped by monitoring the water level, so that the accumulated water in the water collection tank 20 is quickly discharged.
[0037] The submersible sewage pump 1 is fixed to the bottom of the sump 20 by bolts 14. The drainage pipeline of the submersible sewage pump 1 includes a rubber hose 2, a reducer 3 and a galvanized steel pipe 10 connected in sequence. The galvanized steel pipe 10 passes through the side wall of the drainage well and a flexible waterproof casing 8 is arranged between the side wall. The flexible waterproof casing 8 can prevent groundwater from entering the sump, thereby protecting the galvanized steel pipe from the influence of the external environment and preventing the pipeline from being damaged.
[0038] The rubber hose 2 and the reducer 3 can be adjusted according to the head of the submersible sewage pump, which is convenient for later disassembly and maintenance. The steel grille cover 9 can play a filtering role and prevent the risk of people falling. The reducer 3 is connected to the galvanized steel pipe 10 and fixed to the side wall of the drainage well by the pipe clamp 7. The pipe clamp 7 is an Ω-shaped pipe clamp to prevent the galvanized steel pipe 10 from shaking during the drainage process.
[0039] The outlet pipe of the submersible sewage pump 1 is provided with a pressure gauge 4, a check valve 5 and a gate valve 6 in sequence, and the pressure gauge 4, the check valve 5 and the gate valve 6 are arranged above the steel grille cover plate. By installing the check valve 5 and the gate valve 6, it is convenient for the later operation and maintenance personnel to inspect and use and prevent the water in the rainwater well from backflowing.
[0040] The drainage well 23 is located on one side of the rainwater pipe, which is convenient for draining the water in the water collection tank 20. The ductile iron manhole cover 15 and the step 24 are used above the drainage well to facilitate maintenance personnel to enter the drainage well. The step 24 allows the staff to enter the steel grille cover 9 inside the drainage well 23. Through the setting of the pressure gauge 4, the working status of the submersible sewage pump can be understood during the use and maintenance of the submersible sewage pump, so as to find and solve problems in time. It has the functions of monitoring the outlet pressure, judging the status of the pump and ensuring the safe operation of the submersible sewage pump.
[0041] Compared with large-scale pipeline corridors, small-scale pipeline corridors have reduced costs. However, since the internal space of the pipeline corridor cannot meet the normal traffic requirements of personnel, the small-scale comprehensive pipeline corridor drainage system set up in this embodiment allows the pipeline corridor operation and maintenance personnel to operate through the drainage wells 23 set up outside the pipeline corridor to drain the accumulated water in the corridor and ensure that the environment in the corridor is dry; the drainage wells 23 are arranged along the length direction of the small-scale pipeline corridor, and are arranged at set intervals. They can be arranged at the low point of the small-scale pipeline corridor according to the terrain conditions to ensure that the water in the pipeline corridor can smoothly pass through the drainage slope 13, the drainage ditch 12, and the drainage hole 11 into the drainage well 23. The utility model has the characteristics of high automation, fast drainage, and easy maintenance, and can effectively avoid damage to pipes and facilities caused by water accumulation in the pipeline corridor.
[0042] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
