A kind of mechanized construction method of steel bridge deck ers system

Abstract

The invention discloses a mechanical construction method of a steel deck ERS (Epoxy Bonding Chips Layer-Resin Asphalt-Stone Mastic Asphalt) system. The method comprises the steps of (1) preparing materials, (2) derusting by sandblasting, (3) carrying out EBCL (Epoxy Bonding Chips Layer) construction, (4) Spreading RA (Resin Asphalt), (5) producing an RA mixture, (6) transporting the RA, (7) paving the RA, (8) rolling the RA, (9) performing RA surface roughing, (10) carrying out shot interface blasting, (11) spreading a binding layer, (12) producing SMA (Stone Mastic Asphalt), (13) transporting the SMA, (14) spreading the SMA, (15) rolling and (16) carrying out closed maintenance. The mechanical construction method provided by the invention has the characteristics that the labor is saved, the production efficiency of construction is improved, the theoretical construction period is shortened and the cost of labor, machines, materials, management and the like is obviously reduced, also the construction quality is improved and the service life of a paved deck is prolonged.

Description

technical field [0001] The patent of the present invention relates to a mechanized construction method of the steel bridge deck ERS system. Background technique [0002] ERS is an abbreviation for a combination system of steel deck pavement structures, where "E" (EpoxyBondingChipsLayer) is the English abbreviation for epoxy bonded gravel anti-skid layer, "R" (ResinAsphalt) is the abbreviation for resin asphalt concrete, " S" is an abbreviation for SMA pavement. Typical structure of ERS steel deck pavement structure system: EBCL+2.5cmRA05+4cmSMA-13. EBCL is used as a waterproof and anti-skid bonding layer, RA05 is used as a pavement integration layer, stiffness transition layer, and heat insulation layer, and SMA-13 ​​is used as a surface functional layer. In recent years, ERS has been widely used in domestic large and medium-sized bridges due to its advantages of convenient construction, low price, and good performance. At the same time, it has a good application prospect ...

AI Technical Summary

Problems solved by technology

[0003] During the traditional ERS construction work, the key processes such as spreading EBCL gravel and coating of normal temperature resin asphalt adhesive layer oil are all done manually, which is not only time-consuming, laborious and inefficient, but also difficult to ensure uniformity and unreliable construction quality; In terms of concrete mixing plant construction, RA05 is for cold mixing and cold laying, and SMA-13 ​​is for hot mixing and hot laying. It is impossible to take into account that two sites have to be rented to build the station separately, resulting in increased costs
