Description

Technical Field

[0001] The utility model relates to a heightened column foot steel column suitable for the reconstruction of three groups of pre-buried bolt foundations, belonging to the technical field of sound barriers. Background Art

[0002] As an important trackside facility for high-speed railways, sound barriers play an important role in noise control on the one hand, and their structural safety also directly affects operational safety on the other. Since sound barriers are exposed to the open air for a long time, in addition to being subjected to long-term repeated excitation from train wind loads, they are also affected by natural wind, sand, rain and snow, and their structures are prone to fatigue and damage. my country's high-speed railways, such as the Beijing-Shanghai, Beijing-Shijiazhuang-Wuhan, Wuhan-Guangzhou, and Zhengzhou-Xi'an lines, which were opened earlier, have generally been in operation for more than 10 years. In recent years, a series of on-site problems such as loose column bolts and rust have been exposed one after another, and there is a risk of unit panels falling off, which directly threatens the safety of line operations and brings great trouble to relevant departments.

[0003] Compared with the general drawings revised later, the earliest used 09 version of the general drawings of bridge plug-in metal sound barriers for 350km / h passenger dedicated lines (Tonghuan

[2009] 8323,

[2009] 8323A) were all embedded bolts for the column foundation on both sides of the column, especially the three sets of embedded U-shaped bolt foundation. After the unit plate is installed, it is difficult to find the loosening and rusting of the three sets of bolts on the outside in time, and the maintenance and repair during service is difficult. Taking the Wuhan-Guangzhou line, which has been in operation for about 15 years, as an example, it was found during the on-site inspection that some sections of the sound barrier designed with reference to the 09 version of the general drawings had obvious problems such as loose bolts, rusting of structures and connectors, and mortar powdering and emptying, which directly led to the dynamic displacement of the sound barrier columns and unit plates far exceeding the standard limit when the train passed, posing a great safety hazard to driving safety.

[0004] Therefore, it is urgent to design a steel column replacement solution that is easy to inspect and maintain, improves the safety of the sound barrier structure, and can meet the common needs of existing sound barrier unit panels, so as to solve the sound barrier safety problems in the operation of existing lines.
