the installation and preparation stages of the double-ring test monitoring assembly or the double-ring test device and the measurement of the diameter D are mentioned above and are not described herein again;

in the operational phase, when both the first level gauge 117 and the second level gauge 11A reach the set level for the first time (for the first time of each test), the flow meter 113 starts counting Q₀Recording time t0, and recording Q₀T0 and the diameter D are transmitted to the host controller 114, the host controller 114 stores the data, and simultaneously transmits the data (Q0, t0 and the diameter D) to a remote terminal (which can be a mobile phone, a computer and the like) through a data transmitting device (which can be a short message mode, Bluetooth, near field communication NFC and the like).

In the operation stage, the first water level gauge 117 and the second water level gauge 11A are always in the working state, and the water levels of the inner ring 220 and the outer ring 220 are monitored to keep the water levels constant. The inner ring 210 water level is controlled by the first sub-controller 115 and the outer ring 220 water level is controlled by the second sub-controller 118. Taking the inner ring 210 as an example, the water level of the inner ring 210 is lower than the setting water level of the first water level gauge 117, a signal is transmitted to the first sub-controller 115 within the detectable range of the first water level gauge 117, and the first sub-controller 115 sends out a control signal, namely the first valve 116 and the first micro water pump 11C are sequentially opened, so that water is injected into the space of the inner ring 210. When the water level of the inner ring 210 reaches a first water level setting water level, the signal is transmitted to the first sub-controller 115, and the first sub-controller 115 sends out a control signal to close the first micro water pump 11C and the first valve (116), wherein the whole process is controlled by using electric signals, and the time difference can be ignored).

The control principle of the second sub-controller 118 for the water level of the outer ring 220 is the same as that of the first sub-controller 115, and the detailed description thereof is omitted. Because the water level dropping rates of the inner ring 220 and the outer ring 220 are different, the water filling time of the two subsystems is different, the first check valve 11B and the second check valve 11D are arranged in the embodiment, and when the first valve 116 of the inner ring 210 is opened and water is filled, the second check valve 11D of the outer ring 220 is normally in a closed state and cannot affect each other. Even if the first water injection assembly 111 and the second water injection assembly 112 inject water at the same time, the water cannot flow backwards due to the existence of the first check valve 11B and the second check valve 11D, and the mutual independence of the two subsystems is ensured.

After the operation is started, the main controller 114 records the flow rate Q and the time t at fixed time intervals (the flow meter 113 records the accumulated flow rate, and does not return to zero), and calculates the permeability coefficient K according to the formula (1). Recording the flow meter 113Q at time t1_t1As shown in fig. 7, the readings Qt2 of the flow meter 113 at the time t2 and the time t2 after a fixed time interval are taken as examples, and fig. 7 is a graph showing the change of the water injection flow rate value recorded by the flow meter 113 with time in the present embodiment.

Wherein: k represents the average permeability coefficient [ L/T ] over the time period from T1 to T2](ii) a T1 and T2 indicate different recording data times T](ii) a Qt1 represents the corresponding reading [ L ] of the flow meter 113 at time t1³](ii) a Corresponding flowmeter 113 readings [ L ] at times Qt2-t2³](ii) a D represents the diameter [ L ] of inner ring 210 of the double ring assembly]。

The corresponding recording mode of the flow meter 113, for example, starts 5 times of flow recording with a time interval of 5 minutes, and then observes every 20 minutes, and the main controller 114 synchronously stores and sends the flow Q, t and the permeability coefficient K value to the remote receiving end, and the main controller (114) records and judges the flow difference per unit time, and when the flow difference per unit time for 2 consecutive times meets the preset threshold, the preset threshold in this embodiment is set to 5%, that is, the condition shown in formula (2) is met, and the infiltration rate is considered to be stable. The main controller 114 sends instructions to the first sub-controller 115 and the second sub-controller 118, closes the first valve 116 and the second valve 119, sends test results through the data sending device, and sends a test completion signal to remind workers to recover the test device.
