Description
Technical field
The present invention relates to building material field, particularly a kind of preparation method of rainwater pipe.
Background technology
The rainwater pipe generally adopts self-stressing cement as raw material, but stationary phase is long and late expansion becomes serious problem in the production of rainwater pipe greatly.Some rainwater pipes are in use often broken booster because of the excessive steel wire that causes of concrete late expansion, or later stage free wxpansion causes steel wire corrosion after the sag of protecting coating greatly and booster.Sometimes pipe is laid as yet, just occurs damaging on the stockyard, and rainwater pipe length stationary phase and late expansion have been put the problem the technical staff greatly.
Summary of the invention
Technical problem to be solved by this invention provides a kind of preparation method of rainwater pipe, solves rainwater the pipe long and excessive problem of late expansion stationary phase.
For this reason, the present invention adopts centrifugal processing technology, and takes the method that feeds intake for twice, and the distribution of compound on the rainwater tube section is more even, and rainwater pipe packing is significantly improved.In addition, the heating of in forming process, switching on, the steel wire Yin Wendu that disposes in the concrete this moment raises and extends.When concrete hardening, the steel wire that has extended can't shrink recovery, owing to the line differences in expansion of steel wire and haydite composite material produces from stress.After feeding intake for the first time, carry out the energising heating first time, set up primary stress.After feeding intake for the second time, carry out the energising heating second time, set up prestressing force.
Preparation process of the present invention comprises:
(1) batching.Batching is selected haydite, lime, sand, water for use.Proportioning is as follows: the haydite consumption is 25%～28%, and lime consumption is 22%～25%, and the sand consumption is 25%～28%, and water consumption is 22%～26%.
Optimal proportion is 27% for the haydite consumption, and lime consumption is 23%, and the sand consumption is 26%, and water consumption is 24%.Before haydite uses, in water, behind the immersion 24h it is dried earlier.
(2) make steel-wire carcass.
(3) wiring.
The steel wire that is connected with transformer can be selected 6～10, and symmetric arrangement is wanted in the position.
(4) feed intake for the first time.Pipe die low-speed running 3～5min, per minute 120 changes, middling speed running 2～3min, per minute 200 changes.4～the 5min that runs up, per minute 300 changes.Feed intake for the first time and want evenly, THICKNESS CONTROL is at 2cm, strikes off laitance after centrifugal.
(5) energising heating for the first time.Energising heating 5min sets up primary stress.
(6) feed intake for the second time.Pipe die low-speed running 2～3min, per minute 140 changes, middling speed running 3～4min, per minute 280 changes.10～the 12min that runs up, per minute 400 changes.
(7) energising heating for the second time.Energising heating 5min sets up prestressing force.
(8) steam curing
50～55 ℃ of steam curing temperature, the time is about 1h.
(9) demoulding
After reaching 8～12MPa, rainwater pipe intensity carries out the demoulding.
(10) hot water maintenance.
The hot water maintenance divides two stages, and the phase I, normal temperature is warming up to 90 ℃, keeps 1.5h constant temperature; Second stage is carried out maintenance by 90 ℃ of fast coolings to 45 ℃～50 ℃.
Manufacture craft of the present invention is simple, and is easy to operate, invests low.

The specific embodiment
Describe in detail below in conjunction with accompanying drawing.
Preparation process comprises:
(1) batching.Batching is selected haydite, lime, sand, water for use.Proportioning is as follows: the haydite consumption is 27%, and lime consumption is 23%, and the sand consumption is 26%, and water consumption is 24%.Haydite is a kind of porous water-absorbing material, before haydite uses, behind the immersion 24h it is dried in water earlier.
(2) make steel-wire carcass.
(3) wiring.
Electric-heat prestressing is selected the three-phase low-tension transformer for use, uses the star connection method.Transformer should be equipped with variable resistor, should have cooling device simultaneously.The electric wire that picks out on the steel wire from the electric heating transformer adopts insulation soft copper skein silk line.The steel wire that is connected with transformer can be selected the steel wire of 8 symmetric arrangement.
(4) feed intake for the first time.Pipe die low-speed running 3～5min, per minute 120 changes, middling speed running 2～3min, per minute 200 changes.4～the 5min that runs up, per minute 300 changes.Feed intake for the first time and want evenly, THICKNESS CONTROL is at 2cm, strikes off laitance after centrifugal.
(5) energising heating for the first time.Energising heating 5min sets up primary stress.
(6) feed intake for the second time.Pipe die low-speed running 2～3min, per minute 140 changes, middling speed running 3～4min, per minute 280 changes.10～the 12min that runs up, per minute 400 changes.
(7) energising heating for the second time.Energising heating 5min sets up prestressing force.
(8) steam curing
50～55 ℃ of steam curing temperature, the time is about 1h.
(9) demoulding
After reaching 8～12MPa, rainwater pipe intensity carries out the demoulding.
(10) hot water maintenance.
The hot water maintenance divides two stages, and the phase I, normal temperature is warming up to 90 ℃, keeps 1.5h constant temperature; Second stage is carried out maintenance by 90 ℃ of fast coolings to 45 ℃～50 ℃.
The present embodiment heating of switching in rainwater pipe forming process makes the rainwater pipe set up prestressing force, thereby has improved the mechanical property of rainwater pipe greatly.Adopt feed intake for twice after, the pore major part is cut off in the concrete, the anti-permeability performance of rainwater pipe obviously strengthens, concrete density significantly improves, the distribution of batching on pipe section is more even, the late expansion situation is obviously improved.Learn by the cracking resistance contrast test, the pipe that feeds intake for twice, anti-crack ability improves 20%～30%.In addition, have obviously in advance stationary phase by hot water maintenance rainwater pipe, the late expansion rate is also corresponding to be reduced.
