Method for preventing and treating disaster caused by pot cover effect of airport flight area taxiway surface

Abstract

The invention discloses a method for preventing and treating a disaster caused by the pot cover effect of an airport flight area taxiway surface. The method comprises the steps that airport flight area engineering is judged to be newly-built taxiway surface engineering or existing taxiway surface modification engineering, then the newly-built taxiway surface engineering is divided into two conditions, namely, an engineering field area is located in a rich-water area and the engineering field area is located in a non-rich-water area, and the existing taxiway surface modification engineering isdivided into two conditions, namely, the existing taxiway surface base layer is a water-impermeable material and the existing taxiway surface base layer is a non-water-impermeable material; and a corresponding preventing and treating method is provided aiming at the four situations. According to the method for preventing and treating the disaster caused by the pot cover effect of the airport flight area taxiway surface, a water retention scheme for dredging the taxiway surface structure layer is established aiming at the newly-built taxiway surface engineering or the existing taxiway surface modification engineering of the airport flight area, the construction is convenient, the drainage effect is good, and the normal operation of the flight area is not influenced.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a method for preventing and controlling disasters caused by the "pot cover effect" on pavement surfaces in flight areas of airports. Background technique [0002] The "pot cover effect" of the airport pavement refers to the phenomenon that the airtight pavement hinders the evaporation effect of the water in the lower part of the pavement, which causes the water in the lower part of the pavement to be unable to drain and accumulate continuously, and finally leads to a substantial increase in the moisture content of the soil in the lower part of the pavement. The pavement in the flight area of ​​the airport is made of impermeable pavement panels, and the joints between the panels are filled with waterproof materials. This large-area pavement with poor air permeability and water permeability is similar to a "pot cover", which can block the shallow water below it. The excha...

Problems solved by technology

However, there are some difficulties in the implementation of this method. For the new pavement project of the airport, it is difficult to determine the position of laying the hydrophobic air barrier layer, which will affect the prevention effect of the "pot cover effect"; for the existing pavement reconstruction project of the airport, the original If there is a road foundation structure, the engineering volume will be huge, which will affect the operation of the flight area
