Nail type cleft welding machine and construction process

Abstract

The invention relates to a nail type cleft welding machine and a construction process. The nail type cleft welding machine comprises a machine body and is characterized in that the machine body is composed of a power system, a travelling system, a Rayleigh-wave cleft detector, a production system for a cement-stabilizing macadam base softener, a pressure system, a positioning system, a knock-in system, a feeding system, a control system and a control chamber. The construction process comprises the following steps: detection; positioning; injection of the softener; knocking-in of a main nail; injection of a welding material; detection of the welding material; taking-out of the main nail; and cleaning of a construction site. The nail type cleft welding machine has the advantages of fast construction speed, high working efficiency, beautiful surface, small damage to pavements, low production cost and simple construction process.

Description

technical field [0001] The invention belongs to the technical field of asphalt pavement maintenance equipment, and in particular relates to a nail type crack welding machine and a construction process. Background technique [0002] my country is a developing country with limited economic conditions, and it is necessary to vigorously develop road construction. It is undoubtedly a technically feasible and economically reasonable technical solution to choose a semi-rigid base asphalt pavement structure, because: first, the quality of asphalt in our country is not good, The main reason is that the wax content is high (although the wax content has been reduced now, but the index has been unstable), and the output is low and the price is high; second, the quality of raw materials in my country is poor. By adopting the method of stabilizing inorganic binders, the impact on The technical requirements of raw materials, and can guarantee a certain strength; third, the use of semi-rigid ...

AI Technical Summary

Problems solved by technology

Now more than 95% of the highways built in our country are semi-rigid base asphalt pavement. A fatal shortcoming of semi-rigid base asphalt pavement is that reflection cracks cannot be avoided. After cracks appear on the road surface, they must be dealt with in time, otherwise cracks will easily lead to water leakage. Infiltration, when the external load acts on the interior of the structural layer, scour occurs, which leads to the accelerated development of cracks, while the stability of the semi-rigid base is poor, and it is easy to cause water damage, resulting in loose damage to the base, and finally leads to structural damage to the pavement. The better technology to deal with cracks is pavement crack welding technology. When ordinary crack welding machines are used for construction, a hole must be drilled every 1m on the road surface, and for narrow cracks, even a hole must be drilled every 0.5m or so. Drilling requires special drilling rigs, which are slow in construction speed and low in efficiency. After the construction is completed, the surface of the road surface is very unsightly, and too many holes will also affect the structural strength of the road surface. , It is of great significance to the nail type crack welding machine and construction technology with small damage to the road surface, low production cost and simple construction technology
