Description
Technical Field
The utility model relates to a tunnel construction field particularly, relates to tunnel both sides widen anchor section platform truck.
Background
The anchor section is a section which divides the contact net into a certain length along the line and has independent mechanical stability in structure. The tension adjusting device is used in the contact wire and the carrier cable, so that the accident range can be reduced and the maintenance is convenient. The actual length of the contact wire is determined according to the tension difference generated by the contact wire when the temperature changes, and is related to the line condition and the suspension type.
The anchor section is divided into a common composite lining and an anchor section composite lining. The composite lining of the anchor section needs to be widened and heightened. At present, the length of the lining of the general electrified railway anchor section in China is 3 meters, and the section form generally adopts a form that one side is the same as the inner contour line of the general composite lining, and the other side is widened outwards. The construction method is generally carried out by using a common trolley for construction, and the widening section adopts a construction form or a small form as a panel and an arch frame for fixing. Or the construction is carried out by directly adopting the assembly of small templates, scaffolds, arch frames and the like, and the method is generally suitable for anchor sections with the length of less than 3 meters.
For some special projects, the difference between the anchor sections in the mark sections and the original project anchor sections is larger, the lining length of the original project anchor sections is generally 3m, and the lining length of some project anchor sections is other sizes, such as 6 m; in the past, the shape of the anchor section of the project is that one side of an arch wall is consistent with the lining of a general section, the other side of a curved wall is widened from the position of the arch crown, and the two sides of some special projects are widened from the position of a ditch cover plate.
Because the length of the anchor section is long, the widening size is large, the existing lining trolley needs to be modified in the construction process, after concrete pouring is finished, the lining trolley needs to be recovered to continue construction of the common section lining, so that construction period loss is caused, and in order to ensure the construction period, the construction is generally carried out in a mode of skipping the anchor section. The general composite lining trolley is designed only by considering the due widening value of the tunnel plus 5cm (a reserved value), so that the stroke of an oil cylinder and the length of a trolley panel and the like restrict that the lining trolley cannot be directly used in an anchor section, only two lining trolleys can be used as supports, a steel arch frame is added to be used as annular reinforcement, the panel is constructed by adopting a small formwork or bamboo plywood construction process, and the time for modifying the formwork is longer.
