Road and radiator, the interior setting of the water tank of mixing station are used for the jet chimney of mixing water heating, and being arranged on jet chimney can control water
Temperature is not less than 60 DEG C of temp.-control valve；
Third step, the heat preservation of sleeper workshop, the surrounding of sleeper workshop lay the winter for controlling sleeper workshop
Jet chimney of the phase temperature at 10 DEG C or more, sleeper workshop wall and roof setting for prevent sleeper workshop and
The external world generates the rock wool board with flame retarding function of thermal convection, and the window of sleeper workshop is arranged for preventing thermal loss
The air-heater for extraneous cold wind to be isolated is arranged in double glazing, the feed inlet of sleeper workshop；
Double-block type sleeper after demoulding is sent into and closed is equipped with several ultrasonic waves by the 4th step, the maintenance of sleeper finished products after demoulding
The double-block type sleeper for completing 10 day curing period is sent out maintenance workshop by the maintenance workshop of humidifier, and circulation completes the double of every batch of
The maintenance of block type sleeper.
Steam boiler described in the first step is the steam boiler of 4t.
A steam boiler in two steam boilers passes through the jet chimney and water tank of pipeline and sandstone feed bin
Interior jet chimney connection, another steam boiler are connect by pipeline with the jet chimney of sleeper workshop.
The grey trolley of overhead fortune is equipped between the discharge port of the mixing station and the entrance of sleeper workshop.
It sets on the ultrasonic humidifier in the maintenance workshop there are three mutually independent atomization conduit, atomization conduit is equipped with
Several fog outlets, fog outlet setting is between every two rows of double-block type sleepers.
The maintenance workshop is closed structure, conserves and is equipped with automatically between the outlet of the entrance and sleeper workshop in workshop
Go up and down rolling screen door.
Beneficial effects of the present invention are as follows:
By using method of the invention, solves under cold dry adverse weather condition, ensure that double-block type sleeper just
Often production, ensure that going on smoothly for construction period, while guaranteeing the construction quality of sleeper product.
The automatic humidity induction having by the industrial ultrasonic wave humidifier configured and timing means, by the ultrasound of generation
The uniform expanding of wave fog carries out all standing moisturizing, reduces water consumption and the artificial investment of maintenance, eliminate people to sleeper surface
For the leakage that factor generates support and conserve it is not in place caused by mass defect, rejection rate is reduced, so that it is naturally feeding to improve sleeper
Nurse's sequence sleeper quality.

Specific embodiment
In conjunction with attached drawing, the present invention will be further described.
In the environment of teletostage temperature is at -20 DEG C, sandstone feed bin 3, mixing station and sleeper workshop 8 need to keep the temperature extremely
5 DEG C or more, the steam boiler 2 of two 4t is configured, one keeps the temperature for the teletostage of sandstone feed bin 3 and mixing station, and another is used for
The heat preservation of sleeper workshop 8.
Sandstone feed bin 3 faces when building construction, buries jet chimney 4 in subsurface, the heating of sand material when for winter construction,
It prevents from freezing；Jet chimney 4 is laid on the divider wall of sandstone feed bin 3, is maintained at 5 DEG C for the environment temperature in sandstone feed bin 3
More than.The Insulation of mixing station is mainly closed mixing station surrounding using rock wool board, operates 5 position of host and air valve
The position emphasis installation caliduct 7 of cylinder and radiator heat preservation, mixing water are taken jet chimney to place and are risen in water tank 6
Temperature, and install temp.-control valve, steam valve is automatically closed when water temperature is controlled to 60 DEG C, and valve is opened when being lower than this temperature.Guarantee
Concrete out-of-machine temperature is not less than 10 DEG C.
Sleeper workshop 8 teletostage temperature is controlled at 10 DEG C or more, and 8 surrounding of sleeper workshop is mainly taken to lay steam
Pipeline 4 is kept the temperature, and workshop wall and roof, which are all made of rock wool board with flame retarding function and the external world, can not generate thermal convection current phenomenon,
Windowpane in workshop takes double glazing to prevent thermal loss.Entire workshop is at closed state.Mixing station concrete discharging mouth
Take the grey trolley of overhead fortune with the transfer passage in workshop, above entrance wall the extraneous cold wind of 10 pairs of installation air-heater carry out every
From.
The design in workshop 12 is conserved, designs 10 days sleeper maximum outputs first, by practical daily two classes of production 1600
The quantitative design of sleepers, 10 days 16000 sleepers stores floor space.Sleeper is stored according to 8 layers, and every layer of 4 every pile can be deposited
32 are put, occupied area 3.75m2.Area needed for 16000 sleepers are stored is 1875m2, the maintenance workshop 12 of configuration and sleeper
Workshop 8 shares, span 21m, and the length for sleeper caching maintenance is 110m, can meet 10 days sleeper outputs and support
Protect the requirement of time.Ground region scribing line, divides 6 region block pattern row pattern sleepers by 21m span, stays between per pass sleeper storage area
The interval 50cm.
In workshop two sides, every 10m spacing lays ultrasonic humidifier 13,3.2m high above the wall of corresponding humidifier position
Position weld 50cm long T-steel, the corresponding hole for boring 3 φ 10 on T-steel penetrates the wirerope of φ 8, wirerope in each hole
Above the position wall of span 21m to opposite humidifier, 3 wirerope are tensed with cord holder respectively.3 on every humidifier
It says mist pipeline and is individually laid along wirerope, fog outlet stays in 50cm interval location between storage sleeper, per pass fog outlet ladder
Shape is laid.According to said method humidifier is corresponding two-by-two lays fog output tube.Fog output tube and wirerope are fixed by band.
After the completion of fog output tube road 16 is laid, water lines and electric line, the independent water of every equipment are laid along length of walls position
Valve and circuit switch control, unwanted maintenance region can close maintenance of equipment.It is installed in 6 regions away from fog outlet highest distance position
Humidity inductive is popped one's head at 6.Starting ultrasonic humidifier carries out the automatic moisture-keeping maintenance to sleeper after being all installed.
The maintenance workshop is the function and principle by concrete sample standard curing room；It is supported by the moisturizing of code requirement
10 days time of shield and this period sleeper quantity produced plan storage space area, configure certain amount and humidification
Amount meets the supersonic humidifier of maintenance effect, and fog output tube road is laid in installation.By supersonic humidifier it is included be arranged automatically it is wet
The function of degree and time set humidity and enter working condition.Early period is examined by 3 days, 7 days, 28 days with condition test piece intensity
It surveys and determines setting humidity value.Data are obtained through test: demoulding strength 40.8Mpa；3 days intensity be averaged 48.5Mpa(47.8Mpa,
49.3Mpa, 48.5Mpa)；7 days intensity is averaged 54.0Mpa(53.3Mpa, 55.8Mpa, 52.9Mpa)；Intensity is average within 10 days
58.5Mpa(57.6Mpa, 59.5Mpa, 58.5Mpa).
