The flange is externally connected to an automatic uncoupling device, and an electromagnetic flowmeter is provided at the connection between the drainage main pipe and the drainage secondary pipe.

[0006] Preferably, the main drainage pipe, the secondary drainage pipe and the branch drainage pipe are all made of seamless steel pipes, and the pipes are connected by elbows.

[0007] Furthermore, all compartments form a honeycomb structure to enhance the bearing capacity during the sinking of the barrel foundation.

[0008] Furthermore, the pump group also includes a parallel pump group for increasing the drainage volume when the barrel foundation is sunk.

[0009] Preferably, the pipeline control system also includes a detection module and a remote control module. The detection module is used to detect the equipment status information of the compartment, and transmit the equipment status information of the compartment, the drainage water volume and the inclination information of the cabin to the remote control module via wireless signals, and receive the operation instructions issued by the remote control module to remotely control the device of the barrel foundation.

[0010] Preferably, a multi-chamber cylindrical foundation pipeline control method such as a multi-chamber cylindrical foundation pipeline control system comprises the following steps: S1: Open the hydraulic valve on the drainage main; S2: Open the hydraulic valves, opening and closing devices and manual gate valves on all drainage secondary pipes in sequence, and the barrel foundation enters the sinking state; S3: When the barrel foundation is sunk and drained, all opening and closing devices are adjusted according to the electromagnetic flowmeter to control the drainage flow; S4: The barrel foundation tilts during drainage. According to the tilt direction and angle, the compartments to be adjusted are located and detected, and then the flow of the hydraulic valve and the opening and closing angle of the opening and closing device are adjusted to control the drainage flow until the barrel foundation is leveled; S5: After the barrel foundation is sunk, open the automatic unhooking device and recover the pump unit.

[0011] Furthermore, step S4 also includes the following sub-steps: S41: if it is detected that the sub-compartment drainage device to be adjusted is in normal state, adjusting the opening and closing angle of the sub-compartment opening and closing device and regulating the flow of the hydraulic valve; S42: If it is detected that the state of the sub-compartment drainage device to be adjusted is abnormal, the hydraulic valve of the sub-compartment is closed, the hydraulic valve of the sub-compartment on the adjacent side is opened, and the opening and closing angle of the opening and closing device of the adjacent sub-compartment is adjusted.

[0012] Preferably, step S42 further includes, when the cylindrical foundation is severely tilted, opening the hydraulic valves on the adjacent sides of the sub-cabin, increasing the drainage water volume of the sub-cabin, and leveling the cylindrical foundation.

[0013] Furthermore, if it is detected that the hydraulic valve of the sub-compartment and the adjacent sub-compartment fails, the hydraulic valve of the opposite sub-compartment and the opposite adjacent sub-compartment is adjusted to reduce the drainage water volume and level the barrel foundation.
