Abstract

The invention discloses a high-strength and impact-resistant high-speed rail sleeper and belongs to the field of construction. The high-strength and impact-resistant high-speed rail sleeper aims at solves the problems that a sleeper in existing high-speed rail construction is unreasonable in structural design, likely to crack, poor in tenacity and short in service life and comprises a sleeper body and an elastic pad. The sleeper body is provided with rail grooves used for laying steel rails. The rail bottom gradient of each rail groove ranges from 1:30 to 1:20. Slopes are arranged at the two ends of the sleeper body. The gradient of the slopes ranges from 1:2 to 1:10. The elastic pad is located below the sleeper body. Each rail groove is provided with two through holes for fixing the corresponding steel rail. Bosses are arranged at the top ends of the slopes at the two ends. Reinforcing steel bars are arranged in the body in a filled manner. The two ends of each reinforcing steel bar are provided with I-shaped stirrups. II-shaped stirrups are evenly distributed on the reinforcing steel bars. The reinforcing steel bars, the I-shaped stirrups and the II-shaped stirrups are all made of a carbon fiber reinforcement metal composite material obtained through a carbon fiber source, waste carbon fibers and a carbon fiber composite material.

Description

technical field [0001] The invention relates to an infrastructure building material, in particular to a high-strength impact-resistant high-speed rail sleeper. Background technique [0002] With the development of my country's economy, the demand for the railway transportation industry is constantly expanding, especially the demand for high-speed railways is very large. In recent years, the construction of high-speed railways has also made great achievements. The requirements for the track structure are also very high, not only in the stability of the line, but also in the durability, safety, reliability of the track, as well as driving comfort and low vibration. In the laying of train tracks, especially high-speed train tracks, sleepers are an important part of railway tracks, which play an important role in transmitting and dispersing pressure from the rails and the ground, and bearing the impact force from the train. The performance of the sleepers directly affects the per...
