Problems solved by technology

Safety and durability are very important for bridges. If the bridge waterproof system does not meet the specified requirements and standards, the bridge structure will be damaged. Especially for high-speed railways, the pulverization, peeling, peeling, cracking and other phenomena of waterproof concrete will damage the bridge. Waterproof protective layer structure seriously affects the safety of trai

Abstract

The invention discloses a waterproof sealing system for a high-speed railway bridge deck in a severe cold area and a construction method of waterproof sealing system. The waterproof sealing system comprises a protecting wall outside cable duct waterproof system and a between-cable waterproof system and is characterized in that the protecting wall outside cable duct waterproof system comprises a waterproof coating layer and a fiber reinforced concrete protecting layer; the between-cable waterproof system comprises a waterproof coil layer and a fiber reinforced concrete protecting layer. The waterproof sealing system has the advantages that the waterproof coil and C40 fine-stone fiber reinforced concrete are composited to serve as the structure waterproof sealing layer, and the crack resistance and freezing resistance of the concrete are increased; a self-made paving machine is used to perform coil paving to guarantee coil adhering density and increase the effect; a vibration platform isused to perform deck ultrathin glass fiber waterproof concrete pouring, a drainage slope is formed in one step, and cracking after construction is prevented effectively.

Description

technical field [0001] The invention relates to the technical field of railway construction, in particular to a waterproof sealing system for bridge decks of high-speed railways in severe cold regions and a construction method thereof. Background technique [0002] At present, my country's high-speed rail industry has been fully developed. The Beijing-Shenyang passenger dedicated line is newly built. The double-track CRTSⅢ slab ballastless track has a design speed of 350km / h and is located in the severe cold region of Northeast China. Safety and durability are very important for bridges. If the bridge waterproof system does not meet the specified requirements and standards, the bridge structure will be damaged. Especially for high-speed railways, the pulverization, peeling, peeling, cracking and other phenomena of waterproof concrete will damage the bridge. The structure of the waterproof protective layer seriously affects the operation safety of the train. According to the...
