Abstract
The invention discloses a method for leading to a reinforced concrete foundation top slab of a steel tank to receive stress evenly. After the reinforced concrete foundation top slab undergoes casting, screeding and drying, a layer of asphaltic base oil is coated on the slab and then a layer of thin asphalt grout is coated, and finally asphalt mortar is paved, and then the coated top slab is compressed with a flat-plate vibrator to form a soft cushion. Compared with the prior art, the method has the advantages of naturally regulating and balancing, transforming the zigzag type partial concentration stress into the evenly distributed load and passing the load to the lower foundation, greatly increasing the degree of safety of the foundation structure, effectively preventing caustic corrosion and prolonging the service life of the equipment, etc.
Description
Technical field:
The present invention relates to evenly stressed method of a kind of reinforced concrete foundation top board, especially for the even stressed method of the steel tank tank base top board in the alumina producing.
Background technology:
Alumina producing belongs to alkaline leaching technology, and numerous steel tank jars are arranged, and volume is big, and quality is heavy.For example, 14 meters of decomposer diameters, more than 30 meter of height, its steel tank base plate adopt the welding of overlapping batten, reach more than 6000 ton material gross weight is passed to the bottom by the base plate of this indention basis.And prior art is to adopt pea gravel concreten rigidity bed course, and it is difficult for levelling, is difficult for fixing levelness and makes reinforced concrete foundation top board discontinuity, and stress raisers have caused certain potential safety hazard.
Summary of the invention:
The technical problem to be solved in the present invention is:
Provide a kind of even stressed method of reinforced concrete foundation top board that makes the steel tank jar, to solve reinforced concrete foundation top board discontinuity in the prior art, the technical problem of stress raisers.
The present invention is by the following technical solutions:
After the reinforced concrete foundation top board waters and smashes floating drying, brush one bituminous primer thereon earlier, be coated with the rare clay of one deck pitch again, water the black top mortar at last, and use the plate vibrator compacting, form cushion course.
Asphalt mortar, bituminous mortar is made up of pitch, powder, asbestos, sand, and the weight ratio of each component is: pitch 10～18%, powder 10～18%, asbestos 0.7～1.3%, sand 63.6～71%.
The asphalt mortar, bituminous mortar thickness that waters the shop is 45～55mm.
Asphalt mortar, bituminous mortar divides secondary to water the shop, and every layer of empty shop 30～40mm is thick, and after the plate vibrator compacting, thickness 22.5～27.5mm adds glass grid cloth drawknot between two-layer.
The making of watering the asphalt mortar, bituminous mortar of shop is to mix giving heat to 135～145 ℃ powder and sand, adds gradually with the pitch that is about to endure to 200～230 ℃, constantly turn covered by pitch to whole powders and sand till, mix to temperature be 180～210 ℃.
Pitch adopts 10
#Building petroleum asphalt, 90 ℃ of softening points.
Powder and sand adopt alkaline-resisting building stones such as limestone, dolomite, and the solidity index of sand is not less than 93%-98%.
The present invention compared with prior art has following advantage:
1, the asphalt mortar, bituminous mortar that cushion course adopted is a flexible material, when top rough zigzag steel tank base plate is located on it, it can balance correction naturally, zigzag concentration of local stress is turned to evenly distributed load be passed to the basis, bottom, improved the degree of safety of foundation structure greatly, overcome and adopted pea gravel concreten rigidity bed course to be difficult for levelling in the past, be difficult for fixing the disadvantage of levelness and discontinuity.
What 2, adorn in the alumina steel tank jar is the high-concentration sodium hydroxide alkaline material, and concrete foundation is had bigger corrosiveness, and asphalt mortar, bituminous mortar is anti-alkaline material, can effectively prevent caustic corrosion, prolongs the application life of equipment.
The specific embodiment:
Embodiments of the invention:
After the reinforced concrete foundation top board watered and smashes floating drying, one bituminous primer of first thereon brushing was coated with the rare clay of one deck pitch again, treated to begin to water the black top mortar bed behind dried the consolidating.
Asphalt mortar, bituminous mortar is made up of pitch, powder, asbestos, sand, and the weight ratio of each component is: pitch 14.5%, powder 14.5%, asbestos 0.9%, sand 70.1%.
Pitch adopts 10
#Building petroleum asphalt, 90 ℃ of softening points.
Powder and sand adopt alkaline-resisting building stones such as limestone, dolomite, and the solidity index of sand is not less than 93%-98%.
The making of watering the asphalt mortar, bituminous mortar of shop is to mix giving heat to 140 ℃ powder and sand, adds gradually with the pitch that is about to endure to 210 ℃, constantly turn covered by pitch to whole powders and sand till, mix to temperature be 200 ℃.
Asphalt mortar, bituminous mortar divides secondary to water the shop, and every layer of empty shop 35mm is thick, after the plate vibrator compacting, forms cushion course.Its thickness in monolayer is 25mm, adds glass grid cloth drawknot between two-layer, and two layers of thickness is 50mm altogether.
