Roadbed maintenance device for highway construction

Abstract

The invention relates to the technical field of highway construction, and particularly to a roadbed maintenance device for highway construction. The roadbed maintenance device for highway constructioncomprises a base, the hot melting kettle comprises a bottom plate, a hot melting kettle body, a construction mechanism, a pressurizing mechanism, a stirring mechanism and a power supply mechanism, the bottom plate is a square bottom plate and is horizontally arranged, the hot melting kettle body is fixedly installed on one side of the upper portion of the bottom plate through a bottom supportingmechanism, and the construction mechanism communicates with the bottom of the hot melting kettle body. The mounting structure is stable, gravity center more stable, the crack pouring glue in the kettle body can be used more thoroughly without obliquely jacking up the kettle body; the device is simple in structure and convenient to use, waste is avoided, an external high-pressure air source is notneeded, convenience is brought to constructors, meanwhile, the manufacturing and machining cost of the device can be effectively reduced, more importantly, the accident of rollover caused by unstablegravity center of the whole device due to inclined jacking of the kettle body can be avoided, and the influence on the heating efficiency can be avoided.

Description

technical field [0001] The invention relates to the technical field of road construction, more specifically, it relates to a road bed maintenance device and method for road construction. Background technique [0002] Urban roads and highways paved with asphalt often have more irregular cracks after long-term use or due to geographical and heavy vehicles. Asphalt pavement cracks are one of the early major diseases that are most likely to cause other diseases on asphalt pavement under heavy-duty traffic. Asphalt pavement cracks not only destroy the continuity, integrity and aesthetics of the pavement, but also seriously affect the service life of the roadbed and pavement. If effective measures are not taken in time for preventive maintenance and repair, it will cause damage to a larger area of ​​the road and even the complete destruction of the roadbed. [0003] Therefore, it is very necessary to repair the cracks of the roadbed road surface in time. The roadbed maintenance d...

Asphalt pavement cracks are one of the early major diseases that are most likely to cause other diseases on asphalt pavement under heavy-duty traffic. Asphalt pavement cracks not only destroy the continuity, integrity and aesthetics of the pavement, but also seriously affect the service life of the roadbed and pavement. If effective measures are not taken in time for preventive maintenance and repair, it will cause damage to a larger area of ​​the road and even the complete destruction of the roadbed

[0003] Therefore, it is very necessary to repair the cracks of the roadbed road surface in time. The roadbed maintenance device for road construction in the prior art generally includes a hot-melt kettle, a base plate, a seam filling pipe, a top cover, a feeding hopper, a stirring motor, a stirring shaft, and a pushing handle. , electric heating conduit, in order to make the glue inside the hot-melt kettle more thorough and avoid waste, but by installing a cylinder telescopic rod and a main cylinder on the bottom side of the hot-melt kettle, and at the same time cooperate The first fixed block, the second fixed block and the rotating shaft at the bottom of the other side of the hot-melt kettle are used to tilt the hot-melt kettle to the side inclined to the side of the filling pipe. Although this design method can achieve the The use of joint glue is more thorough to avoid waste. However, the problem with this design method is that when using the device, an external high-pressure air source is required, which brings inconvenience to the construction personnel; And the main cylinder, which leads to a significant increase in its manufacturing and processing costs; there is also a serious problem that when the hot-melt kettle is tilted by using the cylinder telescopic rod and the main cylinder, it is easy to cause the center of gravity of the entire device to be unstable and roll over Accidents happen; in addition, it directly installs the electric heating pipe on the inner bottom of the hot-melt kettle, which is easy to cause the outside of the electric heating pipe to adhere to the thick joint glue and affect the heating efficiency. At the same time, the electric heating pipe has been in contact with the The direct contact of the caulking glue leads to a significantly shortened service life; in addition, due to the high viscosity of the caulking glue, when the air pressure inside the hot-melt kettle does not increase significantly, the molten caulking glue flows out of the caulking pipe faster. Slow, even difficult to flow out, which seriously affects the construction efficiency
