An intelligent asphalt joint filling device and method

Abstract

The invention discloses an intelligent asphalt joint filling device and method, comprising a vehicle frame, a traveling wheel arranged at the bottom of the vehicle frame, a slotting mechanism and a cleaning mechanism arranged at the front end of the bottom of the vehicle frame, and a heating mechanism arranged at the middle of the vehicle frame 1. The seam filling mechanism and the scraping mechanism, the compaction mechanism arranged at the rear end of the vehicle frame, the detection mechanism and the marking mechanism arranged at the rear end of the compaction mechanism, and protective mechanisms are arranged on both sides of the middle part of the vehicle frame; on the upper part of the vehicle frame A mixing tank connected to the seam filling mechanism is provided, a heat preservation mechanism is arranged on the frame at the rear end of the mixing tank, a control cabinet is arranged on the frame at the front end of the mixing tank, and a control cabinet is arranged at the front end of the control cabinet There is an operating room. The device and method of the invention can improve the service life of the asphalt pavement.

Description

technical field [0001] The invention relates to a pavement maintenance device, in particular to an intelligent asphalt joint filling device used for maintenance of pavement cracks. Background technique [0002] Asphalt pavement is prone to cracks after long-term use, generally divided into transverse cracks, longitudinal cracks, network cracks, block cracks, etc. Longitudinal cracks usually occur at the junction of the widened new and old pavement or the semi-filled and semi-excavated subgrade, caused by uneven subsidence of the road surface, or at the longitudinal joints of asphalt pavement construction, caused by poor construction joints; or soft foundation treatment is not thorough. Caused; under the action of the driving load, the stress distribution is uneven, forming ruts, and the edges of the ruts are also prone to longitudinal cracks. Transverse cracks are usually caused by the shrinkage of the pavement layer and the uneven distribution of pavement stress due to cha...

Problems solved by technology

[0008] However, the above-mentioned patents still have the following problems: in the process of filling joints, if there is incomplete filling or leaking filling, it cannot be detected, and subsequent quality inspection personnel need to manually hold the replenishing device for replenishing irrigation.

However, a filling process is several kilometers long, and inspectors need to walk or slow down by electric vehicles to complete the detection of leaking irrigation.

Moreover, there is still the problem of detection errors in manual leak irrigation detection, and when leak irrigation or pipes are not solid, it will affect the service life of the asphalt pavement after filling the joints
