Description

DEVICE FOR VIBROLOADING OF PILED FOUNDATIONS OF CONTACT NETWORK SUPPORTS

The proposed utility model relates to railway transport, namely, to the construction of transport equipment designed for vibro-immersion from the railway track of pile foundations under the supports of the contact network and anchors, as well as piles (anchors) for the construction of a prefabricated foundation of supports of flexible cross members for electrification of normal gauge railways, maintenance and overhaul of the railway contact network.

The device is suitable for operation in macroclimatic zones with a temperate climate at an ambient temperature of minus 25 ° С to plus in melt soils.

Currently, for electrification of railways, a four-axle platform mounted vibrator is used to immerse the pile foundations of contact network supports, traffic light masts and other structures erected near the C1 railway.

The vibro-loader has an electric motor that receives current from a special motovo- or power-car.

In cases where it is difficult to load the pile (tightly bound soils, etc.), the vibrator is replaced with a drill or a bucket excavator for excavating the pit.
