The system is installed on the CAP on the basis of self-propelled asfaltorazogrevatele chassis T-16M.
Analysis of temperature fields of heating asphalt pavement layers, as well as modes elektrorazogrevateley
possible to establish a quantitative relationship between the thickness of coating, ambient air temperature, irradiance and duration of heating.
For heating asphalt pavement is also used asfaltootzhigateli mounted on wheeled vehicles and tractors. Operating equipment otzhigatelya consists of a tank of fuel for the process, a fan of high pressure jets and hinged metal umbrella. The fan base is made from the engine gear box through a power take-off, lifting and lowering hydraulic umbrella. Served in the diesel nozzle under the action of the jet of air discharge fan is sprayed to form a combustible mixture that burns under the metal umbrella. The flame heats the road surface until soft. The hot asphalt is cut and removed from the repair area.
Machines for sealing cracks and repair welds. After elimination of cracks in the coating of city streets and roads, resulting in their exploitation, use of special machines and equipment. In accordance with the technology of the repair is the equipment can be cleaned from mud cracks, blow them with compressed air, dry, prime the walls and fill them with putty . The final operation is the sprinkling of the machined surface with sand or gravel screenings. By type of navigation equipment, these machines are divided into hand-held, transported on the truck, trailer and self-propelled.
To use the manual cutting of cracks motorized tools - pnevmolomy, pnevmomolotki, hammers and electric drills.
One promising method is the cutting of asphalt concrete pavement with a jet of hot gases. Gas-jet termoinstrument installed on the machine DE-10, designed for cutting and cleaning of cracks in asphalt surfaces.
We recommend to look
- Remixer
Remixer - is, in fact, the car "Repaver", equipped with additional dosing and mixing units. Warmed up the old asphalt coating loosen knives, and then screw valve and located behind the blade is fed into the mixing unit equipped with two shafts. Fresh mix from the hopper conveyor enters the dosing unit, which sends it to the mixer, where the old and the new mass [...] - The drive compressor
The drive is made from the compressor PTO engine GAZ-53A through the gearbox, driveline and transmission belt. On the gear drive compressors mounted gear pump NSh-10E, which serves the work of hydraulic machines. In the working position hopper hydraulic cylinder rises thermos, allowing automatic translation of the bucket truck-mounted on the rear bodywork and manual vibratory rollers of the transport to working position. Bucket-truck [...] - Machine DE-5A
Machine DE-5A is intended for maintenance of city streets and highways with asphalt. Special equipment vehicles placed on the chassis of GAZ-53A and consists of a hopper-the thermostat for the transportation and storage of hot asphalt mix, with pneumatic compressor, gas equipment - block infrared burners, tanks, hoses, hand tools for painting and road conditions [. ..] - The main features of the machine from the DE-5 model DE-5A
The main features of the machine from the DE-5 model DE-5A - the presence of her benzoelektricheskogo unit and working with electrical equipment (compressor, elektrovibrokatka, elektromolotkov). The hydraulic drive hopper, a thermos and a rear side of the machine is provided with hydraulic cylinders, hydraulic pump mounted on the gearbox mounted on the gearbox car chassis, equipped with a mechanism of inclusion; drive the compressor and elektrovibrokatka elektromolotkov carried out from [...] - Bunker thermos
Hopper provides storage thermos of hot asphalt mix. The mixture is fed into the truck through the open (with cylinder) hopper bin, after which the mixture is transported to the site of work. The torque from the surface of the power takeoff shaft, flanged to the gearbox base unit is transmitted to the input shaft of the hydraulic pump, and from the bottom of the shaft - the input shaft of the generator [...]
