Description

Technical Field

[0001] The utility model relates to the technical field of highway reconstruction, in particular to a highway reconstruction device for preventing roadbed sinking. Background Art

[0002] Highway reconstruction technology refers to the engineering technology for renovating, upgrading or expanding existing highways. With the increase in traffic volume, changes in transportation demand and technological advancement, highway reconstruction has become an important means to improve traffic conditions, safety and service levels. The roadbed is the foundation of the road surface. It is a geotechnical structure formed by excavation or filling. It is an important part of the entire road hierarchy and provides the necessary conditions for the paving of the road surface. The main functions of the roadbed include bearing the static and dynamic loads of the road surface and traffic loads, and transmitting and diffusing these loads deep into the foundation.

[0003] In highway reconstruction projects, in order to reduce the occurrence of foundation sinking, it is necessary to compact the foundation with the help of a compacting device. The existing compacting device generally includes a body, a vibration box, a transmission assembly, a battery box, a motor and a tamping plate. The body is the frame of the entire compacting device. It carries all other components and provides them with a stable installation foundation. The vibration box transfers energy to the tamping plate through the vibration of the internal mechanism, thereby compacting the ground. The transmission assembly is responsible for transferring the power of the motor to the vibration box to ensure that the vibration box can vibrate at a predetermined frequency and amplitude. The battery box is responsible for providing power to the motor to ensure the continuous operation of the entire device. The motor is the power source of the compacting device, which drives the transmission assembly and then drives the vibration box to vibrate. The tamping plate is a component that directly contacts the ground. It transfers energy to the ground through vibration to achieve compaction and compaction of the ground.

[0004] However, the existing compaction device is relatively bulky. When the compaction device needs to be moved to the construction section, or when the compaction device needs to be moved away after compacting the road section, it often needs to be moved onto a transport vehicle for movement, which takes a certain amount of time and is relatively cumbersome to operate, and increases labor costs to a certain extent.

[0005] Therefore, it is necessary to provide a new battery pop-up electronic atomizer structure to solve the above technical problems. Utility Model Content
