Description
Technical field
It the utility model is related to a kind of high Fe in Al-alloy track plates pressing device.
Background technology
Self-compacting concrete layer is played as the important feature part of the plate-type ballastless track structures of CRTS III and held
Open down, transmit the key effect from longitudinal and transverse, the vertical load of upper track structure, its construction quality decides the templates of CRTS III
The success or failure of formula ballastless track structure.Critical material self-compacting concrete as this structure sheaf in track slab precision adjustment due to need to complete
After be irrigated, can not be vibrated, while this layer be as the middle power transmission layer between track plates and base, be required again and track plates
It can be combined closely with base, therefore the construction material of self-compacting concrete layer, ratio requirement are high, to frock and instillation process skill
Art requires also quite strict.Self-compacting concrete is under self gravitation effect, can be flowed, self-compaction, even if existing fine and close
Reinforcing bar can be also filled up completely with, while obtain good homogenieity.Because self-compacting concrete need not vibrate in perfusion, therefore
The time that concreting needs is greatly shortened, and labor strength is greatly lowered, it is necessary to which number of workers is reduced.Therefore from close
Real concrete is progressively applied in the laying of plate-type ballastless track.
In existing self-compact concrete in construction technique, self-compacting concrete layer is arranged between track plates and base,
Need to carry out spacing edge sealing to self-compacting concrete packed layer periphery during form, also to ensure in self-compacting concrete
The discharge of air, while also need to apply self-compacting concrete packed layer above track plates downward pressure, prevent from filling
When noting self-compacting concrete track plates float and skew or accurate adjustment after because artificial the reason for trampling cause track Board position to become
It is dynamic, and in existing construction technology, if taking no action to, cause track plates floating and track plates to be stitched with self-compacting concrete leafing
Phenomena such as, it can bring to construction and greatly endanger.
In the prior art, mostly it is the steel pressing device of use, has weight big, turnover is slow, and easily scuffing destroys track
Plate, so the speed of self-compacting concrete pouring construction is slow, the self-compacting concrete of perfusion always causes track plates floating skew
