Description

technical field [0001] The invention belongs to the technical field of roadbed and pavement engineering, and particularly relates to an intelligent rolling compaction system for subgrade and pavement, which is mainly used for quality control of subgrade and pavement filling and rolling in the fields of highways, railways, airports, dams, bridges, ports and the like. Background technique [0002] The construction quality of subgrade and pavement filling is the key link to ensure the long-term performance of subgrade and pavement and the service life of infrastructure. Poor quality control of subgrade and pavement filling and rolling can easily cause many diseases, such as early road damage, subgrade cracking, uneven settlement of subgrade and subgrade collapse. At present, the subgrade and pavement still mainly use on-site point sampling detection or supervision side station to control the compaction quality and rolling construction parameters of the subgrade and pavement, so...

Problems solved by technology

In terms of online detection methods for compaction quality, there is no effective online detection method for the degree of compaction for earth-rock mixed fill or rock-filled roadbeds with a large particle size distribution, and there is no online detection method that can reflect the overall strength or stiffness of the pavement structural layer. It can be used for continuous, point-line-surface online detection of subgrade road surface flatness, deflection value and settlement method, lack of real-time effective online detection of surface layer asphalt mixture full face rolling temperature method; compaction decision-making methods, In the compaction process, the elastic-plastic deformation in the compaction process of soil and stone cannot be well considered. The existing compaction model does not consider the change of model parameters with the compaction process. The existing compaction model cannot be intelligently adjusted according to the compaction situation. Whether the compaction quality of the filling material meets the requirements in the optimal rolling parameters and the compaction process is still judged by people who are prone to misjudgments and errors; the problems in the control of rolling construction parameters are mainly caused by the construction unit. During the rolling process, the compaction quality is mainly controlled by manual experience, the compaction efficiency is low, and the compaction uniformity is poor. The rolling construction parameters such as the number of rolling passes, rolling track, driving speed, compaction thickness, etc. Problems such as missing rolling, crossing, and repeated rolling occur, and manual driving rolling is not suitable for night, dangerous, and extreme construction conditions on plateaus

In general, the current subgrade and pavement compaction quality monitoring technology still has the problem of human factors interfering with the construction and thus affecting the compaction quality. The quality control mode still focuses on "monitoring" rather than "control", and the construction mode still remains at the stage of manual driving. , the compaction quality is still controlled by manual decision-making, the filling construction quality of the subgrade and pavement cannot be really effectively controlled, and the quality of rolling can not be effectively guaranteed, resulting in different types and degrees of early-stage diseases on the subgrade and pavement, reducing roads, etc. The use quality of the project makes the highway and other projects unable to reach the actual service life
