The impact of the latest developments in geotechnical engineering is rolling compaction technology. Impact roller by a tractor driven by a non-circular scroll wheel, wheel size radius polygon generation gap between potential energy and kinetic energy with a combination of earth and rock material along the face of static, rub, continuous impact shocks rolling operations, forming a high amplitude, low-frequency impact compaction principle. Currently 25KJ triangle Tandem impact roller use up its two-wheeled dead weight 12t, with optimum speed of 12km / h, on the ground to produce a concentrated impact force 200 ~ 250t, equivalent to 1111 ~ 1543kPa. Propagation characteristics of this high-energy impact cyclical continuous strike the ground, a strong shock wave down has seismic waves generated by impact rolling function to achieve super-heavy compaction work, can make deep underground solidity accumulating increased to meet compaction thickness of 90% or more of the heavy compaction standard depending earth and rock material traits of 1.0 ~ 1.5m, better compaction effect than existing mechanical vibration compaction, so that the pressed closer packing of earth and rock elastic state showing earth and rock embankment overcome risks technical advantages.
Road Construction Machines Road Maintenance MachinesConstruction machinery and equipment maintenance methodsStrong maintenance, zero-wait engineering system, its main contents are: the "strong maintenance" as the core, the so-called mandatory maintenance, maintenance is mandatory, you must be on time, because construction must not be tight but not to arrange a time for maintenance personnel. To carry out the modernization of equipment management education to leaders at all levels and facility managers understand good condition and service life of machinery and equipment, to a large extent determine the quality of care at work.
Asphalt Patcher Trailers Technical maintenance machinery such as neglect, only the immediate, mechanical equipment can not operate only until the disabled, the device will inevitably lead to early wear, shortened life expectancy, increased consumption of a variety of materials, and even endanger the safety in production. Not in accordance with the provisions of maintenance equipment, rough use, ignorance of management, which is a modern enterprise and scientific management contrary. "Zero wait" means: after equipment failure waiting to ask maintenance personnel to zero, zero wait asked maintenance spare parts, repair tools ask zero wait, zero wait asked maintenance information. "Strong Zero Project" also has a high value for the highway construction enterprise reference.
Road Construction Machines Road Maintenance MachinesEpilogue "We must first of its profits." Implementation of mandatory maintenance machinery and equipment, the key is to strengthen management, to reform as a driving force, guided by science, people-centered, constraint mechanism as a means, do solid work, and strive to implement the maintenance of the equipment to ensure that machinery and equipment are often in good operating state, and improve the operability of equipment utilization, reduce accidents and unnecessary stoppage loss to provide effective protection for the highway construction mechanization.
