A continuous production line for manufacturing prestressed concrete track slabs for high-speed railways

Abstract

The invention provides a continuous production line for manufacturing a prestressed concrete track board for a high speed railway. The continuous production line comprises a prestressed wire tensioning system, a pouring and vibrating table, a steam maintaining system, a steel mold splicing system and a water maintenance pond. The prestressed wire tensioning system, the pouring and vibrating table, the steam maintaining system, the steel mold splicing system and the water maintenance pond are connected through a transporting system to form the production line. The continuous production line has the advantages that production efficiency is high, structural performance is stable, investment is small, the labor intensity of workers is reduced, and energy is saved; the manufactured prestressed concrete track board is small in prestress degree deviation and even in stress distribution.

Description

technical field [0001] The invention belongs to the field of concrete slab manufacturing, and in particular relates to a continuous production line for manufacturing prestressed concrete track slabs for high-speed railways. Background technique [0002] At present, the international high-speed adjustment railway track slab structure has long-line pedestal method one-way pre-tensioned prestressed concrete track slab and two-way unbonded post-tensioned prestressed concrete track slab. These two kinds of track slabs need to go through multiple procedures to complete. It is to carry out multiple procedures separately, so that the entire production process of prestressed concrete track slabs for high-speed railways becomes longer. At the same time, there are low production efficiency, large investment, many manual operations, and high labor intensity for workers. The complete production line can be transferred. Poor performance, poor environmental protection conditions, large sur...

These two kinds of track slabs need to go through multiple procedures to complete. It is to carry out multiple procedures separately, so that the entire production process of prestressed concrete track slabs for high-speed railways becomes longer. At the same time, there are low production efficiency, large investment, many manual operations, and high labor intensity for workers. The complete production line can be transferred. Poor performance, poor environmental protection conditions, large surface area of ​​concrete track slab curing pool, waste of steam and many other defects
