Steel sheet pile protection system for tidal range area and water level fluctuation area and construction method thereof

Abstract

The invention discloses a steel sheet pile protection system for a tidal range area and a water level fluctuation area. The system comprises a protective deck, a certain distance is reserved between the protective deck and the outer surface of a steel sheet pile, multiple mounting holes are formed in the protective deck, bolts penetrate through the mounting holes, an inner positioning nut and an outer positioning nut are in threaded connection with the portions, located on the inner side and the outer side of each mounting hole, of each bolt, the outer surface, corresponding to each mounting hole, of the steel sheet pile is welded to a fixing nut, and the bolts are in threaded connection with the corresponding fixing nuts, so that a filling cavity capable of being filled with anti-corrosion filling materials is formed between the deck surface of the protective deck and the outer surface of the steel sheet pile, the bottom and the side edges of the filling cavity capable of being filled with the anti-corrosion filling materials are sealed by sealing materials, the filling cavity capable of being filled with the anti-corrosion filling materials is filled with the anti-corrosion filling materials, and the solidified anti-corrosion filling materials and the protective deck together constitute the whole steel sheet pile protection system. According to the steel sheet pile protection system for the tidal range area and the water level fluctuation area, anti-corrosion methods of adopting a coating or uniting the coating with a sacrificial anode or adopting impressed current protection and the like are adopted in an underwater area, and the comprehensive protection of the steel sheet pile can be achieved.

Description

technical field [0001] The invention relates to a protection system for steel sheet piles in tidal range areas and water level fluctuation areas, which belongs to the technical field of seaport engineering anti-corrosion technology, in particular to a protective measure and construction method suitable for steel sheet pile wharf steel sheet pile water level fluctuation areas and splash areas. , so that the steel sheet piles in the marine environment can be reliably protected, and the overall durability of this type of wharf can be improved. technical background [0002] The steel sheet pile wharf is one of the most commonly used wharf structures, and its main substructure is steel sheet piles. The durability of the steel sheet piles determines the service life and safety of the wharf. At present, the anti-corrosion methods for steel sheet piles mainly include coating, sacrificial anode and impressed current and the combination of these three methods. Among them, sacrificial...
