Problems solved by technology

It is not a real "assembly type". Due to its complex process, difficult control, long cycle and high cost, it is difficult to promote and apply it on a large scale. Only a small number of partial pilot projects have been carried out at home and abroad.

Embodiment 1

[0046] combine Figure 1 to Figure 4 , a new airport prefabricated pavement system, including a track foundation 1 and a base layer 2 arranged on the track foundation, a flexible transition layer 3 and an assembled prefabricated track panel 4 are arranged on the base layer 2 . Accurate airport pavement is achieved through the precision control method for the flatness of the foundation and the top surface of the base layer, the construction control method for the flexible transition layer, the precise positioning and installation method for the prefabricated pavement panel, the detachable connection structure of the pavement panel, and the rapid replacement method for the prefabricated pavement panel. Quick installation and replacement maintenance.

Embodiment 2

[0048]The new airport prefabricated pavement system, through the precision control method of the ground and the top surface of the base layer, the construction control method of the flexible transition layer, the precise positioning and installation method of the prefabricated road panel, the detachable connection structure of the road panel and the rapid replacement of the prefabricated road panel method to realize accurate and rapid installation, replacement and maintenance of airport pavement.

[0049] The methods for controlling the flatness accuracy of the foundation and the top surface of the base course include the following:

[0050] Step A1: Control the accuracy of the foundation, the bottom of the base layer, and the base layer from bottom to top, and improve the accuracy of the flatness layer by layer, thereby reducing the impact of the unevenness of each layer on the compaction operation of the upper layer;

[0051] Step A2, using a digital automatic control system...

Embodiment 3

[0056] The new airport prefabricated pavement system, through the precision control method of the ground and the top surface of the base layer, the construction control method of the flexible transition layer, the precise positioning and installation method of the prefabricated road panel, the detachable connection structure of the road panel and the rapid replacement of the prefabricated road panel method to realize accurate and rapid installation, replacement and maintenance of airport pavement.

[0057] The construction control methods of the flexible transitional layer include the following:

[0058] Step B1, using a flexible coiled material to lay above the base layer, and setting up and down two layers of flexible coiled material, and laying the upper and lower coiled material transition layers with staggered joints;

[0059] Step B2, when laying the flexible coil, use professional roll-laying equipment for positioning and laying to further control the surface flatness o...

Abstract

The invention discloses a novel airport assembly pavement system, which includes a field foundation, a base layer arranged on the foundation, a flexible transition layer, and a prefabricated road panel; a method for controlling the flatness precision of the field foundation and the top surface of the base layer, and a flexible transition layer The construction control method, the precise positioning and installation method of the prefabricated pavement, the detachable connection structure of the pavement and the rapid replacement method of the prefabricated pavement realize the accurate and rapid installation, replacement and maintenance of the airport pavement. This system and method improves the quality and durability of the airport pavement, avoids the wet operation of concrete in the construction of the airport pavement, greatly improves the mechanization and intelligence level of construction, effectively reduces the amount of labor, and significantly shortens the on-site pavement construction period. In order to greatly improve the efficiency and convenience of airport track construction, operation and maintenance in areas with poor weather conditions, short construction period and resource scarcity. At the same time, the time required for maintenance and replacement of road panels is greatly reduced, which better meets the needs of high-efficiency operation of busy transport airports.

Description

technical field [0001] The invention relates to the field of airport pavement construction, in particular to a novel airport assembly pavement system. Background technique [0002] At present, my country's airports mainly use cast-in-place cement concrete pavement. The construction of the cast-in-place pavement surface mainly includes formwork making and formwork support, mixing of mixture, transportation of ingredients, paving, vibration of mixture, leveling and lifting, surface A series of processes such as surface making, surface roughening, health preservation, groove carving, seam cutting, seam expansion, seam cleaning, and seam filling. Due to the influence of human factors, environmental change factors, and low technical requirements, there are many construction restrictions, long cycle times, high energy consumption, high pollution, large quality dispersion, poor durability, etc., and maintenance is difficult, long cycle, and high cost. , The whole life cycle technic...
