When the pipeline laying device is used, the support compensation devices can be installed at intervals along a pipeline laying path, and the arc inner diameter of the bearing plate is matched with the outer diameter of the conveying pipeline, so that the conveying pipeline can stably stay at the lowest position of the bearing plate after being placed on the bearing plate. Like this, after the installation of accomplishing support compensation arrangement, on direct hoist and mount pipeline to the bearing plate, the connecting tube just can accomplish the pavement of pipeline, need not additionally fixed, compares anti-settling methods such as cement powder shotcrete stake, and the construction is simple swift more. Meanwhile, the supporting plunger oil cylinder between the supporting plate and the base can vertically extend and retract under the oil pressure action of the energy accumulator, and is in a contraction state under the designed elevation of the pipeline and the pressure of the pipeline and the soil body above the pipeline. Once the soil below a certain supporting and compensating device is settled, the base moves downwards together, the pipeline is supported by other supporting and compensating devices at the same time, the position is basically kept unchanged, the pressure acting on the supporting plunger oil cylinder is reduced, the supporting plunger oil cylinder extends under the oil pressure action of the energy accumulator to compensate the settlement amount of the soil and continues to be supported below the pipeline, as shown in fig. 3, the supporting plunger oil cylinder of the supporting and compensating device positioned in the middle is longer than the extension amounts of the supporting plunger oil cylinders at the two ends, so that the serious bending and even breakage caused by hanging the pipeline at the settlement section can be avoided, and the use safety and reliability of the pipeline are improved.

Therefore, after the pipeline is placed into the supporting plate, the elastic ball body can generate corresponding deformation after being stressed so as to play a role in damping the pipeline.
During specific use, for improving the precision, the extension amount of the piston of the supporting plunger oil cylinder and the detection data of the pressure sensor can be calibrated, and the specific steps are as follows: the energy accumulator, the supporting plunger oil cylinder and the pressure sensor which are of the same type are adopted, and hydraulic oil with a quantitative volume is filled between the energy accumulator and the supporting plunger oil cylinder, wherein the quantitative volume is the hydraulic oil amount filled in the energy accumulator and the supporting plunger oil cylinder during construction. A hydraulic press and other devices are adopted to apply pressure to a piston supporting a plunger oil cylinder, so that the piston is in a contraction state, and then an energy accumulator is pressurized to a set pressure. Reducing the pressure that is used in on the piston, making the piston at the uniform velocity extension, the piston is after the extension setting distance at every turn, and the pressure and the total elongation that corresponds that gather pressure sensor and detect, so relapse, until the piston rod stretches out completely, through the relation between the data fitting piston rod elongation that gathers and the pressure that pressure sensor detected. During monitoring, the monitoring host can convert the elongation of the piston rod according to the acquired detection data, and once the elongation of a certain supporting plunger oil cylinder exceeds the set elongation, the settlement of the certain supporting plunger oil cylinder is judged to exceed the design standard and needs to be maintained, otherwise, the maintenance is not needed.
According to the settlement monitoring and compensating system for the underground conveying pipeline, when the settlement monitoring and compensating system is used specifically, the settlement monitoring and compensating can be carried out by adopting the following method:
