Description
Technical field
A kind of bridge precast beam low hydration heat of the present invention is prefabricated to use internal lining pipe and its method for prefabricating, is related to a kind of bridge bearing
Internal lining pipe and its method for prefabricating when framework is prefabricated, belong to road and bridge construction field.In particular to a kind of by the way that range will be poured
Control in a certain range, enables the heat of hydration to be balanced, and by repeatedly pouring, and weakens that whole aquation is thermogenetic to answer
The prefabricated of power uses internal lining pipe and its method for prefabricating.
Background technique
Currently, in order to shorten the period, a large amount of load-bearing framework is all that synchronous progress is prefabricated, so during bridge construction
After transport to scene and be combined, shorten the construction period, especially in short Super Engineering of some span large-engineering periods, by
It is huge in structure size, it needs to combine by exterior sheathing and reinforcing bar when carrying out prefabricated, then once be poured using concrete
Completion is built, but since concrete generates big calorimetric when carrying out hydrated, position biggish for dimensional thickness, inside and outside temperature difference
Increase, is easy cracking, it is therefore desirable to constantly cool down, so that the heat of hydration is quickly spread, but since medium position is difficult to
It reaches, therefore there are risks, it is existing to be implanted into steel pipe in concrete, fluid is injected into steel pipe, and hot friendship is carried out by fluid
Change so that middle portion temperature declines, but the hole that steel pipe is reserved at middle part so that integral strength declines, and steel pipe and concrete it
Between combination, heat transfer it is poor, and section is smaller, the thermal Finite that can take away poor to the support of concrete, cannot be gradually
Break up heat of hydration bring stress.
Publication number CN204983667U discloses a kind of built-in type circulating cooling for reducing the mass concrete heat of hydration
Pipe, it is characterised in that: the built-in type circulating cooling pipe includes the cooling water pipe being placed in concrete and is placed in outside concrete
First connection water pipe, the second connection water pipe, the cooling water pipe are by a plurality of lateral cooling water pipe and a plurality of longitudinal cooling water pipe
Composition, a plurality of transverse direction cooling water pipe is distributed parallelly in concrete, and the section of every lateral cooling water pipe is matrix pattern, a plurality of
Longitudinal cooling water pipe is distributed between adjacent two lateral cooling water pipelines, and two adjacent transverse cooling water pipes are connected；
The water outlet that the water inlet port of cooling water pipe connect water pipe with first connects, and cooling water pipeline water outlet port connect water pipe with second
Metal end connection, second connection water pipe water outlet with first connect water pipe water inlet pipe pass through water circulating pump connection, the party
Method is taken away the heat of hydration by water body flow, but since size is big, the thermal Finite that tube body can be taken away, the alleviation to the heat of hydration
Effect is general, and at the construction field (site), and the installation sealing and flow control of tube body are more complex.
