Abstract

The invention discloses an inner surface coating tool for a bridge and tunnel steel immersed tube. The inner surface coating tool comprises an inner beam and two gantry supports for lifting the innerbeam. The inner beam is provided with a sand blasting/spraying robot and a transverse moving mechanism, the sand blasting/spraying robot is movably mounted on the inner beam through the transverse moving mechanism and can transversely move along the inner beam, and the gantry supports are mounted at the two ends of the inner beam. Gantry support bases are arranged at the bottoms of the gantry supports and mounted on rails located on the ground and drive the gantry supports to longitudinally move along the rails through longitudinal transverse mechanisms. According to the inner surface coatingtool, the gantry supports are located on the two opening end faces of the steel immersed tube and can longitudinally move along the ground rails, the two gantry supports can be accurately matched to enable the inner beam to rise and fall, a platform where the robot is located can slide along the inner beam, the platform and the inner beam act coordinately, and thus sand blasting/spraying full-covering operation of the side face/top face of the inner surface of the steel immersed tube can be achieved.

Description

technical field [0001] The invention relates to an inner surface coating tool for bridge and tunnel steel immersed pipes, belonging to the technical field of bridge and tunnel construction. Background technique [0002] The construction of bridges and tunnels is an important project in the strategic planning of complex transportation networks, which is related to the national plan. Steel structure engineering has the characteristics of fast construction speed and strong load-bearing capacity, and is widely used. However, the disadvantage of poor corrosion resistance of large steel structures makes later maintenance more difficult. Its durability guarantee is an important consideration in the overall life design of bridges. The construction method of protective coating has a decisive impact on the quality of paint film and work efficiency. [0003] It is the first large-scale application of steel immersed tubes in the subsea tunnel of the deep-middle passage, which is the fi...
