Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0014] Reference Figure 1-4A device for preventing mortar sedimentation in a sewage tank includes a sewage tank 1 and an inspection port 5 on the side wall of the sewage tank 1 for easy access to clean mortar and prevent sedimentation and blockage. The sewage tank 1 has inlet and outlet ports for connecting to the tunnel boring machine's sewage system. A visual level window 6 is located on the side wall of the sewage tank 1 for easy monitoring of the water level. If the water level is too high, sewage is discharged promptly. An exhaust pipe 2 is located on the upper side of the sewage tank 1 and communicates with the interior of the sewage tank 1. If the pressure inside the sewage tank 1 is too high, air is released to prevent deformation or damage to the sewage tank 1 due to excessive pressure. The sewage tank 1 has a drain outlet 7 on one side of the bottom for draining sewage and sediment, which facilitates regular cleaning of the sewage tank 1. The drain outlet 7 is equipped with a manual valve 71 to control the opening and closing of the drain outlet 7. The sewage tank 1 is connected to an air pipe 3, one end of which is connected to an air supply pipe 4. The air supply pipe 4 is connected to an air compressor. The air compressor supplies air into the air supply pipe 4, which is then sprayed out through the air pipe 3. This serves to flush the bottom of the sewage tank 1, preventing the mortar sediment at the bottom of the sewage tank 1 from accumulating. The sewage inside is in a state of agitation and turbulence, which improves the problem of sedimentation and hardening of the A liquid backwash slurry. The air tube 3 includes a vertical tube 301, a horizontal tube 302, and an air vent tube 303. One end of the air vent tube 303 is connected to the horizontal tube 302. The horizontal tube 302 is connected to the air supply tube 4 through the vertical tube 301 for supplying air. The other end of the air vent tube 303 is provided with a cleaning port 30. The connection between the horizontal tube 302 and the vertical tube 301 is provided with a maintenance pipe hole 32. If the air vent tube 303 becomes clogged, it can be flushed and cleaned through the cleaning port 30 and the maintenance pipe hole 32. A one-way valve 31 is provided on the horizontal pipe 302, which is set vertically in conjunction with the vertical pipe 301 to provide double protection and prevent sewage from backflowing into the gas supply pipe 4. A control valve 33 is provided on the vertical pipe 301 to control the opening and closing of the vertical pipe 301. The vent pipe 303 is made of galvanized steel pipe and is installed at the bottom inside the sewage tank 1. The bottom wall of the sewage tank 1 has a longitudinal protrusion in the middle to guide the mortar sedimentation trend and concentrate it to both sides for easy cleaning. The vent pipe 303 is set corresponding to the protrusion of the sewage tank 1. The number of vent pipes 303 is selected according to the needs. If there are few particles, one vent pipe 303 can be configured. If there are many sediments, two to three vent pipes 303 can be configured and evenly distributed at the bottom inside the sewage tank 1. When there are multiple vent pipes 303, at least two vent pipes 303 should be equipped at the lower part of the protrusion on both sides to ensure the mud stirring and rolling effect and avoid sedimentation and hardening. The vent tube 303 has vent holes, and there are multiple sets of vent holes, which are evenly distributed on the lower side of the vent tube 303 to reduce the amount of sediment entering the vent tube 303. If only one vent tube 303 is configured, vent holes can be evenly opened on the surface of the vent tube 303 to increase the jet volume and improve the stirring effect. A vibrating plate 8 is fixedly installed on the lower side of the protruding part of the sewage tank 1. There are multiple sets of vibrating plates 8, which are evenly distributed on the lower side of the sewage tank 1. A transmission rod 81 is fixed through the multiple sets of vibrating plates 8. A vibration device 82 is provided at one end of the transmission rod 81. The vibration device 82 is a vibration motor. When the vibration device 82 is working, it transmits the vibration to the vibrating plate 8 through the transmission rod 81, causing the bottom wall of the sewage tank 1 to vibrate, which helps to clean the hardened sludge.

[0015] In this embodiment, the sewage system of the tunnel boring machine is discharged through sewage tank 1. The sewage in the A liquid backwashing pipeline contains mud and flows into sewage tank 1. In order to avoid sedimentation, air needs to be introduced to stir and roll it. The air compressor is turned on and air is supplied to the air pipe 3 through the air supply pipe 4. The control valve 33 is opened and the air passes through the vertical pipe 301, the horizontal pipe 302 and the one-way valve 31, and finally sprays out through the air hole on the air hole pipe 303 to stir and roll the mud and sewage. After prolonged use, the air vent pipe 303 needs to be cleaned regularly, the control valve 33 needs to be closed, and the air vents need to be backwashed through the cleaning port 30 and the inspection pipe hole 32 to avoid blockage and affect air ejection. In addition, the vibration device 82 can be turned on periodically, and the vibration plate 8 can be driven by the transmission rod 81 to vibrate and impact the bottom wall of the sewage tank 1, which facilitates the cleaning of sediment and avoids mud caking.
