Construction technique of prefabricated runway panels of airfield runway

Abstract

The invention provides a construction technique of prefabricated runway panels of an airfield runway. The construction technique comprises the following steps that (1) the prefabricated panels of the airfield runway are prefabricated; (2) the prefabricated panels of the airfield runway are transported; and (3) the prefabricated panels of the airfield runway are installed. A method for prefabricating the prefabricated panels of the airfield runway comprises the steps of (1) production preparation, (2) concrete proportioning design, (3) preparation of a mould for the prefabricated panels of the airfield runway, (4) steel bar machining and framework manufacturing, (5) mould cleaning, (6) brushing of a releasing agent, (7) mould assembly, (8) installation of a steel reinforcement framework, (9) pouring and vibrating of concrete, (10) forming and plastering of concrete, (11) steam curing of prefabricated blocks of the panels of the airfield runway, (12) demolding of the prefabricated blocks of the panels of the airfield runway, (13) water curing and (14) finished product inspection. According to the construction technique, the construction quality is guaranteed, maintenance cost for quality defects is reduced, materials are used most reasonably, the utilization rate of the materials is guaranteed, material waste is prevented, both the construction quality and the construction technique of the airfield runway are greatly improved, and meanwhile, the construction annual cycle of runway projects is greatly shortened.

Description

technical field [0001] The technical field of the airport runway of the present invention, in particular relates to a construction process of the prefabricated track panel of the airport runway. Background technique [0002] The concrete pavement of the airport is designed according to the flexural strength. Generally, there is no steel bar in the pavement slab, and the concrete bears the bending and tensile stress. When concrete is subjected to tension, it is very sensitive to defects such as cracks and pores in the concrete. Under repeated loads, cracks are easier to expand and cause damage, so the concrete is required to have a good internal structure and homogeneity. Pavement concrete is paved in an open-air environment on a large scale, and is subject to long-term damage from climate and environment, such as insufficient vibration during the paving process, formwork leakage, repeated temperature strain, dry-wet cycle, freeze-thaw cycle, etc. . Using the cast-in-place ...

Problems solved by technology

Using the cast-in-place process, the quality of the concrete pavement should not be controlled, and quality problems are prone to occur. At the same time, in the cast-in-place process of the concrete pavement, separate warehouses are required, and the overall construction progress is slow
