Description

Settlement preventing system and method for half-width construction of municipal road Technical Field The invention relates to the technical field of municipal road engineering, in particular to a half-width construction anti-sedimentation system and method for municipal roads. Background With the acceleration of the urban process, the expansion and reconstruction projects of municipal roads are increasing. In order to relieve traffic pressure during construction, such projects usually adopt a half-width construction and half-width traffic operation mode, namely splicing and paving of new roadbed are carried out on the other side while normal traffic of the road on one side is maintained. However, this mode of construction faces extremely complex geomechanical challenges. The sedimentation characteristics of the new roadbed and the old roadbed are quite different due to the huge difference of consolidation time. The old roadbed is stable under the long-term driving load effect, and the new roadbed is still in the active settlement period, so that the uneven settlement is very easy to generate longitudinal cracks at the joint of the road center, and the service life and driving safety of the road are seriously affected. Although the engineering world widely adopts the technologies of geogrid reinforcement, deep mixing pile reinforcement or high-pressure grouting and the like to strengthen the strength of a new roadbed at present, the methods essentially belong to passive static reinforcement methods. Once the subgrade is settled beyond expectations in the later construction period or the initial operation period, the pre-buried static structure cannot be subjected to subsequent remediation or adjustment, and the subgrade can be repaired only by re-excavation or repeated grouting, so that the subgrade is high in cost and can seriously interfere with normal traffic operation. In addition, in the special environment of semi-traffic, frequent traffic of heavy vehicles in close proximity to the construction area can generate continuous high-frequency vibration. The vibration not only accelerates the loosening and sedimentation of the new roadbed filling soil, but also brings forward serious test to the traditional sedimentation monitoring and controlling technology. The existing automatic monitoring equipment is difficult to distinguish elastic vibration caused by vehicles and plastic sedimentation of soil mass, so that data distortion is caused, and if the existing hydraulic jacking equipment is directly applied to such a scene, the existing hydraulic jacking equipment is very easy to forcedly jack up at the moment of passing of heavy vehicles due to misjudgment, or seal failure and pressure relief are caused by long-term bearing of dynamic alternating load, so that long-term, stable and intelligent active sedimentation compensation cannot be realized. Disclosure of Invention The invention aims to provide an anti-sedimentation system and method for half construction of municipal roads, which solve the problems that in the half construction of municipal roads, uneven sedimentation of new and old roadbeds cannot be actively repaired in the later period, and conventional regulating equipment is out of alignment and easy to damage in monitoring under the interference of heavy traffic vibration. In order to achieve the above purpose, the invention is realized by the following technical scheme: the utility model provides a half construction of municipal road prevents subsiding system, includes the road bed deep, the deep top of road bed is provided with basic supporting component, basic supporting component top is provided with dynamic adjustment subassembly, the dynamic adjustment subassembly outside is provided with the auto-lock subassembly, dynamic adjustment subassembly top is provided with interface buffer module, install the controller on the basic supporting component; The controller is configured to: the data processing module is used for receiving the original height data acquired by the dynamic adjusting component, adopting a low-pass filtering algorithm to process the original height data, stripping high-frequency vibration components caused by vehicle passing, and extracting low-frequency components representing soil settlement as effective settlement values; The cooperative computing module is used for executing multipoint linkage computation based on the pavement continuity model, and computing the cooperative adjustment quantity of the neighborhood node taking the position as the center when judging that the position needs to be adjusted according to the effective sedimentation value, so that the adjustment amplitude of the adjacent nodes is in smooth attenuation distribution; and the execution control module is used for driving the corresponding dynamic adjusting component to perform vertical jacking compensation according to the cooperative adjusting quantity and controlling the self-locking componen
