[0012] The method for using the pipeline laying tunnel boring machine comprises the following steps: Step 1: Pipe hole excavation: First, fix the tunnel boring machine inside the working pit, and then use the crane to place the equipment shell inside the tunneling slot on the top of the equipment base. At this time, start the hydraulic rod, which drives the top pipe base at one end to fit with the docking opening at one end of the equipment shell. At this time, the hydraulic rod pushes the equipment shell at one end of the top pipe base to move along the tunneling slot toward the soil layer; Step 2: Discharging soil: When the tunneling head moves toward the inside of the soil, the soil excavated by the cutter base enters the inside of the tunneling head. At this time, the drive motor on the soil discharge base is started. The output end of the drive motor rotates to drive the conveyor belt to rotate. The rotation of the tunneling head drives several soil-discharging baffles inside the tunneling head to rotate. At this time, the soil-discharging baffles transfer the soil inside the tunneling head to the conveyor belt. The conveyor belt rotates to transport the soil to the outside of the equipment casing. Step 3: Auxiliary cleaning: When the tunneling head rotates and drives several earth-moving baffles to rotate, the cleaning column at one end of the cleaning rod on the right side of the rotating rod rubs against the inside of the tunneling head; Step 4: Compact the inner wall of the tunnel: the tunneling shaft drives the reset spring on the limit ring to contract, and the movement of the tunneling shaft drives the push rod on the moving ring to move toward the inside of the tunneling head. The push rod drives the sliding block at one end of the connecting rod to slide along the sliding groove toward the outside of the tunneling head. The sliding block drives the extrusion roller to slide toward the outside of the tunneling head. At this time, the extrusion roller is squeezed against the inner wall of the tunnel.

[0013] The present invention has the following beneficial effects: (1) The present invention provides a cleaning mechanism. When the excavation head rotates and drives a plurality of earth-moving baffles to rotate, the cleaning column at one end of the cleaning rod on the right side of the rotating rod rubs against the inside of the excavation head. This arrangement is conducive to the cleaning column to scrape off the soil adhering to the inner wall of the excavation head. The scraped soil falls onto the conveyor belt and is discharged along with the conveyor belt. When the earth-moving baffle rotates to the cleaning mechanism and is squeezed by the cleaning column, the earth-moving baffle drives the rotating rod on the cleaning rod at one end of the cleaning column to rotate. At this time, the cleaning column rubs against the surface of the earth-moving baffle. This arrangement is conducive to the cleaning column to remove the soil on the surface of the earth-moving baffle, thereby avoiding The soil-moving baffle is prevented from sticking a large amount of soil on the surface, thereby improving the soil-moving efficiency of the soil-moving baffle; when the soil-moving baffle drives the rotating rod on the cleaning rod at one end of the cleaning column to rotate, the rotating rod drives the torsion of the torsion spring on the fixed ring to increase, and at the same time, the limit rod on the cleaning rod slides along the limit slide groove. This arrangement is conducive to ensuring that the cleaning column rotates stably along the rotating rod. When the soil-moving baffle is separated from the cleaning column, under the torsion of the torsion spring, the torsion spring drives the cleaning rod at one end of the rotating rod to reset, and the cleaning rod drives the cleaning column to reset. This arrangement is conducive to the cleaning column to continuously clean the surfaces of several soil-moving baffles inside the tunneling head.

[0014] (2) In the present invention, when the tunnel boring machine is used for laying pipelines, the tunnel boring machine is first fixed inside the working pit, and then the equipment shell is placed inside the tunneling groove on the top of the equipment base by a crane. At this time, the hydraulic rod is started, and the hydraulic rod drives the top pipe base at one end to fit with the docking opening at one end of the equipment shell. At this time, the hydraulic rod pushes the equipment shell at one end of the top pipe base to move along the tunneling groove toward the soil layer; the tunneling motor is started, and the rotation of the tunneling motor drives the output shaft at the output end to rotate, and the rotation of the output shaft drives the tunneling shaft to rotate, and the rotation of the tunneling shaft drives the tunneling drill bit to rotate, and the rotation of the tunneling shaft drives the connecting ring on the sliding key to rotate, and the rotation of the connecting ring drives the tool base to rotate, and the rotation of the tool base drives the tunneling head to rotate along the tunneling disk, and the rotation of the tool base drives several cutter heads Rotation, such an arrangement is conducive to the excavation of soil by several cutter heads in the excavation mechanism. By placing the equipment casing inside the excavation slot, it is conducive to ensuring that the excavation head at one end of the equipment casing drills into the soil along a straight line, while ensuring the stability of the equipment casing, thereby improving the quality of pipe hole excavation; when the equipment casing is completely drilled into the soil, the hydraulic rod drives the jacking pipe base to move to the end close to the extrusion base. At this time, the segmented pipe is placed into the excavation slot through the crane. At this time, the hydraulic rod drives the jacking pipe base to move to the tail of the segmented pipe again. At this time, the jacking pipe base pushes the segmented pipe to move to the docking opening of the equipment casing. At this time, the docking opening fits with one end of the segmented pipe, and the hydraulic rod drives the jacking pipe base to continue pushing the segmented pipe into the pipe hole, thereby completing the laying of the segmented pipe.

[0015] (3) The present invention provides a soil discharge mechanism. When the tunneling head moves toward the inside of the soil, the soil excavated by the cutter base enters the inside of the tunneling head. At this time, the drive motor on the soil discharge base is started. The output end of the drive motor rotates to drive the conveyor belt to rotate. The rotation of the tunneling head drives a plurality of soil-moving baffles inside the tunneling head to rotate. At this time, the soil-moving baffles transfer the soil inside the tunneling head to the conveyor belt. The conveyor belt rotates to transport the soil to the outside of the equipment housing. This arrangement is conducive to timely discharge of the excavated soil, thereby increasing the excavation rate.

[0016] (4) The present invention provides a pressing mechanism. When the tunneling head at one end of the equipment housing is pressed against the soil, the tunneling drill bit at one end of the tunneling shaft is pressed against the soil. The tunneling drill bit is pressed against the soil and drives the tunneling shaft to slide along the output shaft. At this time, the tunneling shaft drives the return spring on the limit ring to contract. The movement of the tunneling shaft drives the push rod on the moving ring to move toward the inside of the tunneling head. The push rod drives the sliding block at one end of the connecting rod to slide along the sliding groove toward the outside of the tunneling head. The sliding block drives the extrusion roller to slide toward the outside of the tunneling head. At this time, the extrusion roller is pressed against the inner wall of the pipe hole. This arrangement is conducive to compacting the soil on the inner wall of the pipe hole and preventing the soil inside the pipe hole from falling off, thereby improving the quality of the pipe hole.
