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 type of airport prefabricated pavement system and method, including a field foundation 1 and a base layer 2 arranged on the field foundation, and a flexible transition layer 3 and an assembled prefabricated road 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 and method, through the accuracy 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 pavement, the detachable connection structure of the pavement and the prefabricated pavement The rapid replacement method realizes the accurate and rapid installation, replacement and maintenance of the 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...

Embodiment 3

[0056] The new airport prefabricated pavement system and method, through the accuracy 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 pavement, the detachable connection structure of the pavement and the prefabricated pavement The rapid replacement method realizes the accurate and rapid installation, replacement and maintenance of the 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 fla...

Abstract

;The invention discloses a novel airport fabricated pavement system and method. The novel airport fabricated pavement system comprises an airport pavement foundation, a base layer, a flexible transition layer and a prefabricated pavement slab; accurate and rapid installation, replacement and maintenance of the airport pavement are achieved through a pavement foundation and base layer top surface flatness precision control method, a flexible transition layer construction control method, a prefabricated pavement slab accurate positioning and installation method, a pavement slab detachable connection structure and a prefabricated pavement slab rapid replacement method. According to the system and the method, the quality and durability of the airport pavement are improved, concrete field wet operation of airport pavement construction is avoided, the mechanization and intelligence level of construction is greatly improved, the labor consumption is effectively reduced, the field pavement construction period is remarkably shortened, and in regions with poor weather conditions, short construction period and resource shortage, the construction, operation and maintenance efficiency and convenience of the airport runway are greatly improved. Meanwhile, the time for maintaining and replacing the pavement slab is greatly shortened, and the requirement for high-efficiency operation of a busy transportation airport is better met.

Description

technical field [0001] The invention relates to the field of airport pavement construction, in particular to a novel airport assembly pavement system and method. 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 cy...
