Isolating layer paving device for special-shaped complex area of airport and construction method

Abstract

The invention relates to the technical field of airport building engineering, in particular to an isolating layer paving device for special-shaped complex area of an airport and a construction method. The device comprises an adjusting frame, rollers are arranged at the lower end of the adjusting frame, and an adjusting base driven by a telescopic rod is slidably mounted at the upper end of the adjusting frame; a plurality of sets of guide rail plates installed perpendicular to the moving direction of the adjusting base and linearly connected is arranged in an inner cavity of the adjusting base, the lower ends of the guide rail plates are slidably inserted into the upper end of the adjusting base, and a pair of sawtooth strips which are meshed with the driving gear and are symmetrical front and back are arranged at the upper ends of the guide rail plates. The invention has the beneficial effects that the guide rail plate driven and adjusted by the gear is arranged, so that stable transverse feeding of the guide rail plate is achieved, a construction end is driven to extend, workers are prevented from stepping on a wide road surface in the construction process, accurate construction is achieved on the premise that the road is protected, and the forming quality of the road is greatly improved.

Description

technical field [0001] The invention relates to the technical field of airport construction engineering, in particular to a paving device and a construction method for an isolation layer in a special-shaped complex area of ​​an airport. Background technique [0002] After the airport project is completed and opened to navigation, it will go through a long process of use. During this period, the pavement has to bear the action of service load and be eroded by natural forces such as wind, rain, ice and snow, freeze-thaw, sun exposure, etc., which will inevitably lead to a decline in its use function and aircraft load performance. In order to ensure the driving function of the pavement, the old pavement is generally rebuilt. Usually, the old pavement is sprayed with sticky oil, then non-woven geotextiles are laid, and finally the new pavement is paved. [0003] At present, the common practice is to use pavement asphalt spreader to spray a large area. However, due to the long c...

Problems solved by technology

[0003] At present, the common practice is to use pavement asphalt spreader to spray a large area. However, due to the long construction time of the follow-up process and the concrete process itself, it will pollute the geotextile, and the filling construction is more obvious, which affects the performance of the geotextile. Ultimately affecting the durability of pavement engineering

The formwork in the complex shaped area was previously made of wooden formwork, which is easy to deform and the construction cannot meet the design size requirements. At the same time, due to the complex structure of the shaped area and the large construction area of ​​the airport road, it is inevitable to improve the construction accuracy during the construction process. cause people to step on the road during the construction process, thus affecting the molding quality

[0004] To this end, a device and construction method for laying isolation layers in special-shaped complex areas of airports are provided to solve the problems of old road surface covering and accurate construction in special-shaped complex areas of airports
