Offshore permeable airport runway and construction method thereof

Abstract

The invention discloses an offshore permeable airport runway which comprises a foundation pile, and a shelving support is arranged at the top of the foundation pile; a prefabricated box girder is arranged on the shelving support, the prefabricated box girder comprises a plurality of prefabricated box girder sections which are sequentially and longitudinally connected, every two adjacent prefabricated box girder sections are connected through a cementing material, and the prefabricated box girder sections are connected into a whole in a pre-pressing mode through post-tensioning method prestress steel strands; every two adjacent prefabricated box girders are connected into a whole through a cast-in-place connection wet joint; the surface layer paving facility is paved on the top of the prefabricated box girder; the invention discloses a construction method of the offshore permeable airport runway. According to the invention, the utilization of sand and gravel can be greatly reduced, the construction cost is reduced, resources are saved and utilized, on the premise that the existing water flow state is not changed as far as possible, ecological environmental protection of a sea region near the engineering site is facilitated, smooth discharge of surface runoff of a near-shore land region near the engineering site into the sea is facilitated, and water exchange is conveniently realized; the offshore water quality is improved.

Description

technical field [0001] The invention relates to the technical field of traffic airports, in particular to a permeable airport runway. Background technique [0002] Coastal and nearshore areas are one of the important spaces for human activities. This area often has a particularly high population density and a highly prosperous economy, but land resources are very scarce, and the transportation demand for land resources is particularly large. Therefore, making full use of the offshore shallow water space (sea area less than 30m deep) for the planning and construction of traffic airport runways can effectively alleviate the difficulty of insufficient land resources in coastal areas, and has particularly important strategic and economic significance for transportation. Therefore, it is necessary to study the construction technology of offshore artificial airport runways, which can effectively save land resources and avoid the noise impact of land-based airport runways on coast...

Problems solved by technology

However, the disadvantages mainly include: 1) It has a great impact on the coastal marine ecological environment; 2) It requires a large amount of sand and gravel filling materials; 3) It affects the development and distribution of land surface runoff and causes various adverse scouring and silting changes on the coastline. Especially the flood discharge function that affects the surface runoff in the rainy season
