Description
Technical field
The present invention relates to technical field, more particularly to a kind of non-batch production sleeper prefabricated construction engineering method.
Background technology
Sleeper used by current China engineering is largely prefabrication, under the stacker-reclaimer track of Rizhao Iron Ore Terminal stockyard
For prefabricated concrete sleeper, totally three thousand polylith, is limited by quantity and cost.Although in recent years, to gradually form batch production prefabricated for sleeper
Production, for the larger engineering of demand be than better suited, but for smaller and higher to the appearance requirement engineering of project scale,
It is also good selection to carry out at the scene prefabricated.During non-batch production is prefabricated, template and clear-water concrete should be paid attention to
Design and construction.
The content of the invention
It is an object of the invention to provide in view of the shortcomings of the prior art it is a kind of ensure the prefabricated quality of sleeper, safety and
Duration, effectively instruct the non-batch production sleeper prefabricated construction engineering method of small-sized sleeper precast construction construction.
To achieve these goals, the technical solution adopted in the present invention is as follows：A kind of non-batch production sleeper prefabricated construction
Engineering method, comprises the following steps：
(1) stencil design and processing：From all-steel mold plate, design 33 sets of side forms of processing, 99 sets of bed dies；
(2) template surface PROCESS FOR TREATMENT：Releasing agent is coated in template surface, coating thickness is controlled in 0.05~0.2kg/
m2, time control 24h before formwork erection is smeared, smearing finishes and uses covered rearing with plastic film；
(3) model sheetinstallat：Template in manufacturing process, by sleeper lay above make end template, it is and pre- on bed die
Pre-embedded bolt is stayed, construction is overturned, it is up big and down small；During formwork erection, carry out installing bed die first, place the steel processed
Muscle cage, then installs surrounding template again；
(4) steel bar meter is installed：Sleeper reinforcing bar is at the scene after machine-shaping, and artificial lift is put into mould；
(5) concrete former material is detected：Alkali content≤0.6%, C3A content≤8% of cement；Coarse aggregate from intensity it is high,
Continuous grading, same color, clay content<1.0%th, elongated particles<5% and without debris rubble；Fine aggregate selects fineness
Modulus is 2.4~2.8, clay content<1.5% middle sand, solid colour and free from admixture；Admixture selects flyash, ground slag
One kind in powder, natural zeolite powder；
(6) mix Design：Clear-water concrete mix-design is carried out with dense skeleton method of piling；
(7) casting concrete：Pouring work includes perfusion, consolidates and finishing process of wiping one's face, and concrete transportation is using small-sized
Carriage, slump must be strict controlled between 60mm~90mm；
(8) form removal is conserved：Maintenance should cover the exposed face of whole concrete structure, should be first by concrete during watering maintenance
The side and bottom surface of structure are sufficiently humidified so as to, and are then sprinkled water again by top surface.
Described flyash is from I grade of flyash.
The beneficial effects of the present invention are the engineering method forms complete set, scientific and reasonable sleeper template, clear water and mixed
Solidifying soil engineering construction process, effectively directs small-sized sleeper precast construction construction, solves small members template complexity, concrete
The problems such as blibbing is more, template turnover inconvenience, it is ensured that the prefabricated quality of sleeper, safety and duration.
Brief description of the drawings
Fig. 1 is the block diagram of non-batch production sleeper prefabricated construction engineering method.
