Description

Technical Field

[0001] The present application relates to the technical field of integrated pipeline construction, and in particular to an integrated pipeline structure suitable for narrow spaces and a construction method thereof. Background Art

[0002] With the construction and development of modern cities, traditional buildings such as ancient city districts and ancient blocks are increasingly valued and protected as China's material cultural heritage. The streets and alleys between adjacent buildings in traditional ancient blocks are relatively narrow and located in difficult-to-excavate areas, which has caused certain difficulties for construction workers to lay out sewage pipes and rainwater pipes. How to lay out integrated pipelines in a small space has become an urgent problem that people need to solve. Summary of the invention

[0003] In order to facilitate the laying of integrated pipelines in a small space and save space, the present application provides an integrated pipeline structure suitable for a small space and a construction method thereof.

[0004] In the first aspect, the present application provides an integrated pipeline structure suitable for a narrow space, which adopts the following technical solutions:

[0005] A comprehensive pipeline structure suitable for a narrow space comprises a combined box culvert buried underground in streets and alleys, the combined box culvert comprises a rainwater box culvert and a sewage box culvert arranged below the rainwater box culvert, a rainwater collecting pipe is connected to the outside of the rainwater box culvert, and one end of the rainwater collecting pipe away from the rainwater box culvert is connected to the ground; a sewage pipe is arranged inside the sewage box culvert, the sewage pipe is connected to the sewage collecting pipe, the sewage collecting pipe is passed through the sewage box culvert and is used to be connected to the sewage discharge pipes of residents in the streets and alleys.

[0006] By adopting the above technical solution, after the rainwater box culvert of the present application is superimposed on the sewage box culvert to form a combined box culvert, the combined box culvert is buried underground in the streets and alleys, which can save space and enable construction personnel to smoothly lay out a series of integrated pipelines such as sewage pipes and rainwater pipes in narrow streets and alleys. Among them, the rainwater collection pipe is directly connected to the rainwater box culvert. When it rains, rainwater can flow into the rainwater box culvert through the rainwater collection pipe, and finally flow into the municipal drainage pipe along the rainwater box culvert for discharge.

[0007] The sewage pipe is set inside the sewage culvert, which can weaken the squeezing effect of the external soil on the sewage pipe, and at the same time reduce the possibility of corrosion of the sewage pipe by chemical substances in the soil, which is beneficial to extend the service life of the sewage pipe; the domestic sewage generated by residents on both sides of the streets and alleys is discharged into the sewage pipe through the sewage collection pipe, and finally can be discharged into the municipal sewage treatment pool along the sewage pipe.

[0008] Optionally, a plurality of inspection valve ports are provided at the bottom of the rainwater culvert, and each of the inspection valve ports is connected to the sewage culvert; and each of the inspection valve ports is provided with a cover that can be opened and closed.

[0009] By adopting the above-mentioned technical solution, when the sewage pipe is partially blocked, the street ground is excavated to expose the rainwater culvert, the rainwater culvert is opened and the cover inside the rainwater culvert is opened. Maintenance personnel can enter the sewage culvert through the inspection valve and inspect and maintain the sewage pipe, thereby improving the convenience of cleaning the sewage pipe.

[0010] Optionally, the sewage pipe includes a plurality of sewage pipe sections erected inside the sewage culvert, and a spherical silt collection box is slidably connected between adjacent sewage pipe sections; the sewage pipe section located at the front end of the water flow direction of two adjacent sewage pipe sections is set as the first sewage pipe section, and the sewage pipe section located at the rear end of the water flow direction is set as the second sewage pipe section;

[0011] The silt collection box is provided with a first communication port connected to the first sewage pipe section and a second communication port connected to the second sewage pipe section, the first communication port is provided with a reverse interception mechanism for preventing foreign matter in the water supply from flowing into the silt collection box in one direction, and the second communication port is provided with a water filtering mechanism for filtering sewage;

[0012] A lifting and flipping mechanism for driving the silt collection box to rotate is provided inside the rainwater culvert, and the lifting and flipping mechanism is partially penetrated through the inspection valve port; when the lifting and flipping mechanism is actuated, the lifting and flipping mechanism drives the first connecting port of the silt collection box to rotate to a position directly opposite the inspection valve port.

[0013] By adopting the above technical solution, the domestic sewage generated by the residents is discharged into the sewage collection pipe and then flows into the sewage pipe. After the foreign matter in the sewage enters the silt collection box through the first connecting port, it can be intercepted by the water filtering mechanism, and the water body can continue to flow forward through the water filtering mechanism; the reverse interception mechanism at the first connecting port can reduce the possibility of foreign matter flowing out of the silt collection box in the reverse direction, so that the foreign matter can be better collected in the silt collection box. When there is too much accumulation of foreign matter in the silt collection box and blockage occurs, by controlling the action of the lifting and flipping mechanism, the lifting and flipping mechanism can rotate the side of the silt collection box with the first connecting port to a position facing the inspection valve port. At this time, maintenance personnel can remove foreign matter in the silt collection box by salvaging on the rainwater culvert or street road surface, which can be applied to situations where the streets are narrow and it is difficult for maintenance personnel to enter the sewage culvert.

[0014] Optionally, the reverse interception mechanism includes a plurality of sheet-like screens arranged around the inner wall of the first connecting port, and adjacent sheet-like screens are arranged at intervals; each of the sheet-like screens is hinged to the silt collection box, and a torsion spring is installed at the hinge between the sheet-like screen and the silt collection box, and the torsion spring normally causes the sheet-like screens to be retracted towards each other.

[0015] By adopting the above-mentioned technical scheme, the torsion spring of the present application normally causes the sheet screens to be retracted with each other; when sewage with foreign matter flows into the sewage pipe, the foreign matter in the sewage first accumulates on the side of the sheet screen away from the water filtering mechanism, and as the foreign matter continues to accumulate, the foreign matter gradually partially blocks the sheet screen; as the sewage is continuously discharged, the amount of sewage in the sewage pipe increases, and the pressure acting on the sheet screen increases continuously, which can cause the sewage to flush the sheet screen and force the sheet screen to rotate in the direction close to the water filtering mechanism, thereby flushing the foreign matter into the silt collection box; then the sheet screen is reset to the mutually retracted position under the action of the torsion spring, thereby reducing the possibility of foreign matter flowing out from the first connecting port in the opposite direction, so that the foreign matter is better collected in the silt collection box.

[0016] Optionally, the water filtering mechanism includes a water filtering mesh plate movably mounted on the second connecting port, and a first connecting rope is provided between each of the sheet screens and the water filtering mesh plate, one end of the first connecting rope is connected to the outer peripheral side of the water filtering mesh plate, and the other end of the first connecting rope is passed through the inner wall of the silt collection box and connected to the side of the sheet screen away from the hinge between itself and the silt collection box.

[0017] By adopting the above-mentioned technical solution, the water filter mesh plate can play the role of blocking foreign matter and filtering sewage; the water filter mesh plate of this embodiment is movably installed at the second connecting port, and when the lifting and flipping mechanism is controlled to rotate the first connecting port of the silt collection box to a position directly opposite to the inspection valve port, the maintenance personnel can use tools to lift the water filter mesh plate upward, and at this time the water filter mesh plate can drive the foreign matter collected in the silt collection box to move upward, and at the same time the water filter mesh plate can pull the connected first connecting rope and move each sheet screen away from each other, and finally the water filter mesh plate can pass through the area between each sheet screen and move to the first connecting port, thereby bringing the internal foreign matter out of the silt collection box, which can further improve the convenience of maintenance personnel in cleaning foreign matter.

[0018] Optionally, a grid is fixed in the middle of the water filter screen plate, and the grid is used for being clamped and fixed by an external clamping device; when all the sheet screens are closed together under normal conditions, a clearance space is formed for the clamping device to pass through.

[0019] By adopting the above-mentioned technical solution, when it is necessary to clean foreign objects in the silt collection box, the maintenance personnel can pass the clamping device through the clearance space between each sheet screen and go deep into the silt collection box, and then control the movement of the clamping device to clamp and fix the grid, and then lift the clamping device to enable the water filter screen to move upward smoothly.

[0020] Optionally, the inner wall of each sewage pipe section is provided with a through transfer port, and a sewage diversion pipe is slidably installed on the outer side of each transfer port, and two adjacent sewage diversion pipes located on both sides of the silt collection box are connected to each other; each sewage diversion pipe is provided with an arc-shaped block at one end close to the sewage pipe section, and the arc-shaped block normally blocks the transfer port; the lifting and flipping mechanism is used to connect with two adjacent sewage diversion pipes, and when the lifting and flipping mechanism is actuated, the sewage diversion pipe moves to a position connected with the transfer port, and the first connecting port of the silt collection box is rotated to a position opposite to the inspection valve port.

[0021] By adopting the above-mentioned technical solution, when one of the silt collection boxes in the sewage pipe is blocked and needs to be cleaned, the maintenance personnel control the lifting and turning mechanism in the rainwater culvert to drive the silt collection box to rotate while also moving the two adjacent sewage diversion pipes to a position connected to the transfer port. At this time, the two interconnected sewage diversion pipes can serve as channels for sewage flow, so that the sewage generated by the residents can still be discharged normally without the need for interception operations, further improving the convenience of maintenance personnel in repairing sewage pipes.

[0022] Optionally, the lifting and flipping mechanism includes a winding drum fixed to the inner wall of the rainwater culvert and a second connecting rope connected to the winding drum, the second connecting rope is passed through the inspection valve port and connected to two hinges, and the two hinges are respectively connected to opposite sides of the two sewage transfer pipes;

[0023] A hinged plate is provided between each of the sewage diversion pipes and the adjacent silt collection box, and the hinged plate is rotatably connected to the sewage diversion pipe via a first rotating shaft, and the hinged plate is rotatably connected to the silt collection box via a second rotating shaft; the first rotating shaft and the second rotating shaft are normally located in the same axial direction of the sewage pipe, and when the winding drum winds up the second connecting rope, the connecting direction of the two second rotating shafts is arranged perpendicular to the axial direction of the sewage pipe.

[0024] By adopting the above technical solution, maintenance personnel control the winding drum to rotate on the street pavement or in the rainwater culvert, and the winding drum can gradually wind up the second connecting rope and drive the two hinges to move upward, so that the sewage diversion pipes connected to the two hinges move in a direction close to each other, and each sewage diversion pipe can move to a position connected to the transfer port. The two sewage diversion pipes can respectively push the hinged plates to rotate while moving relative to each other, one hinged plate flips upward, and the other hinged plate flips upward, and finally the silt collection box can be rotated 90 degrees in the vertical plane, so that the first connecting port of the silt collection box is rotated to a position directly opposite to the inspection valve port.

[0025] Optionally, a tension spring is provided between each of the sewage diversion pipes and an adjacent sewage pipe section, and the tension spring normally causes the sewage diversion pipe to move in a direction away from the adjacent sewage diversion pipe.

[0026] By adopting the above-mentioned technical scheme, when the winding drum is in motion, the winding drum can wind up the second connecting rope and drive the two sewage diversion pipes closer to each other, thereby causing the tension spring to undergo elastic deformation; when the foreign matter in the silt collection box is cleaned up, the winding drum is controlled to rotate in the opposite direction, and the tension spring can gradually reset and move the two sewage diversion pipes away from each other, and finally the arc-shaped block on the sewage diversion pipe can match and block the transfer port of the sewage pipe section, thereby reducing the possibility of sewage flowing into the sewage diversion pipe and causing blockage inside the sewage diversion pipe, so that the sewage diversion pipe can be used smoothly when the silt collection box is cleaned next time.

[0027] In the second aspect, the present application provides a construction method for an integrated pipeline using the following technical solution:

[0029] Step S1, digging trenches on the street ground;

[0030] Step S2, burying the combined box culvert; after the sewage collection pipe is placed in the sewage box culvert, the rainwater tank cover is fitted into the sewage box culvert, and the combined box culvert is buried in the trench;

The two hinges 63 are respectively connected to the opposite sides of the two sewage diversion pipes 7; when the winding drum 61 is controlled to rotate and the second connecting rope 62 is wound, the two sewage diversion pipes 7 can move in a direction close to each other. At this time, the two sewage diversion pipes 7 can move to a position connected to the transfer port 321, so that the maintenance personnel do not need to intercept the flow when repairing and cleaning the sewage pipe 3, which further improves the convenience of repairing the sewage pipe 3.
