Embodiment 1

[0035] A construction method for overlaying concrete prefabricated slabs on airport pavement, such as figure 1 As shown, its construction method includes the following steps:

[0036] Step 1 Damage treatment of the original pavement surface: the original pavement is cement concrete pavement,

[0037] A) Use a cutting machine to cut the damaged area of ​​the original road surface into a regular pentagon,

[0038] B) Use a breaker to break the original road surface in the rectangular area, remove the damaged part to the hard layer, and form a repair pit

[0039] C) Remove the original road surface materials and floating dust in the repair pit, and leave no loose gravel, floating ash, oil, sewage and other sundries on the base,

[0040] D) Use quick-setting quick-hardening mortar to fill and repair pits, vibrate and compact with a flat plate, and smooth the surface;

[0041] Step 2 Pave the isolation leveling layer:

[0042] A) Pave an isolated leveling layer on the surface o...

Embodiment 2

[0053] A construction method for overlaying concrete prefabricated slabs on airport pavement, such as figure 1 As shown, its construction method includes the following steps:

[0054] Step 1 Damage treatment of the original pavement surface: the original pavement is asphalt concrete pavement,

[0055] A) Use a cutting machine to extend the damaged area of ​​the original road surface by 30cm and cut it into a regular rectangle.

[0056] B) Use a small milling machine to break the original road surface in the rectangular area, remove the damaged part to the hard layer, and form a repair pit,

[0057] C) Remove the original road surface materials and floating dust in the repair pit, and leave no loose gravel, floating ash, oil, sewage and other sundries on the base,

[0058] D) The bottom and four walls of the repair pit are evenly coated with sticky layer oil, and the asphalt mixture is used for layered paving and compaction. The thickness of a single compaction is not greater...

Embodiment 3

[0071] A construction method for overlaying concrete prefabricated slabs on airport pavement, such as figure 1 As shown, its construction method includes the following steps:

[0072] Step 1 Damage treatment of the original pavement surface: the original pavement is cement concrete pavement,

[0073] A) Use a cutting machine to cut the damaged area of ​​the original road surface into a regular hexagon

[0074] B) Use a breaker to break the original road surface in the rectangular area, remove the damaged part to the hard layer, and form a repair pit

[0075] C) Remove the original road surface materials and floating dust in the repair pit, and leave no loose gravel, floating ash, oil, sewage and other sundries on the base

[0076] D) Use quick-setting quick-hardening mortar to fill and repair pits, vibrate and compact with a flat plate, and smooth the surface

[0077] Step 2 Pave the isolation leveling layer:

[0078] A) Pave an isolated leveling layer on the surface of th...

Abstract

The invention relates to a construction method for additionally laying concrete precast slabs on an airport pavement, and discloses a construction method for additionally laying the concrete precast slabs on the airport pavement without suspending aviation service. The construction method for additionally laying the concrete precast slabs on the airport pavement without suspending the aviation service comprises the steps of (1) carrying out surface damage processing on an original pavement, (2) laying an isolation leveling layer, (3) laying the concrete precast slabs, (4) carrying out joint processing, carrying out processing on reserved connecting grooves of the concrete precast slabs, (5) carrying out connection between a newly-laid pavement and the original pavement, (6) carrying out runway shoulder processing, and (7) carrying out linking runway processing. The construction method for additionally laying the concrete precast slabs on the airport pavement without suspending the aviation service solves the problem of additionally laying the concrete precast slabs on the airport pavement without suspending the aviation service, firstly, targeted processing is carried out on damage of the original pavement, then, the concrete precast slab integral assembly covering technology is used for carrying out additional laying construction on the concrete precast slabs, construction is carried out at night according to the requirement for construction without suspending the aviation service, sequential connection slopes are additionally laid between the new pavement and the original pavement after construction at the night is accomplished, normal operation of flights of the next day cannot be influenced, and the requirement for construction without suspending the aviation service is met.

Description

technical field [0001] The invention relates to a construction method for overlaying concrete prefabricated slabs on airport pavement, in particular to a construction method for overlaying concrete prefabricated slabs on airport pavement without stopping. Background technique [0002] At present, more than 80% of domestic airports in my country use cement concrete rigid pavement. When the old pavement needs structural overlay due to aging or insufficient bearing capacity, it can only be paved with asphalt mixture under non-stop conditions. If you want to overlay cement concrete surface, it can only be implemented under the condition of airport non-stop. Contents of the invention [0003] Aiming at the deficiency that the existing airport pavement reconstruction and paving cement concrete surface course need stop construction, the invention proposes a construction method for non-stop paving concrete prefabricated slabs on the airport pavement. [0004] In order to solve th...
