Technical field
This utility model belongs to technical field of civil engineering, relates to a kind of deep-etching saline soil area foundation protection node, and the durability relatively conventional foundation on basis is greatly improved, and can make basis normal operation in design life.
Background technology
Power Plant Buildings thing basis safety and reliability for power plant safe operation it is critical that.And in saline soil area, it is easy to the corrosion of building base concrete occurring, crack occurs, peel off and lose the phenomenon of bearing capacity gradually, the loss that especially infringement of deep-etching effect causes is particularly huge.
In saline soil area, cause that the corrosivity Slope protection of base concrete is a lot, according to the feature of salinized soil, mainly due to the sulfate and the villaumite corrosion failure to armored concrete that exceed certain content in soil.In current domestic electrical design specification, it does not have saline soil area basic engineering is made special regulation, simply perform with reference to relevant regulations in petroleum pipeline industry standard " saline soil area construction standards ".Deep-etching does not have in " saline soil area construction standards " integrated treatment measure the technical parameters such as clear and definite strength grade of concrete, cement type, additionally, the coating scope of outer protection is indefinite, coating layer thickness is indefinite, and way is indefinite.
Based on above-mentioned present situation, the safety in operation and the reliability that improve Power Plant Buildings thing basis, deep-etching saline soil area are significant.
Utility model content
The purpose of this utility model is in that the shortcoming overcoming above-mentioned prior art, a kind of deep-etching saline soil area foundation protection node is provided, the guard technology parameter on this basis is clear and definite, durability relatively conventional foundation is greatly improved, it is applicable to deep-etching saline soil area, it is ensured that basis normal operation in design life.
The purpose of this utility model solves by the following technical programs:
This deep-etching saline soil area foundation protection node, including the overcoat on basis and parcel basis；The bottom on described basis is provided with bed course, is fixed with structural column 4 in described basis.
Above-mentioned basis and structural column are reinforced concrete structure.
The both sides on above-mentioned basis are hierarchic structure, and the end face on basis and the negative and positive angle of side are all done circular arc and processed.
Above-mentioned overcoat is followed successively by from the inner to the outer: cold primer oil reservoir, asphalt adhesive mud layer and modified asphalt waterproof coiled material layer；Described overcoat indoor bag is to terrace place, and outdoor bag is to aproll place.
The surface of above-mentioned overcoat is wiped with cement mortar protective course.
Above-mentioned bottom bed course adopts bituminous concrete bed course, and thickness is 150mm；Bottom bed course includes: grain formula bituminous concrete and 20mm thickness asphalt mortar, bituminous mortar top screed-coat in 130mm thickness；Main body based on the bed course width of bottom extends 150mm to outer.
Above-mentioned bottom bed course upper surface lays 4mm thickness modified asphalt waterproof coiled material " SBS ", pastes with side of the base plate modified asphalt waterproof coiled material " SBS " overlap joint and closes up, pastes width be more than or equal to 100mm.
Further, less than zero meter structural column side Minimum Concrete Protective Coating Thickness is 50mm, sets reinforced mesh in layer.
This utility model has following benefit effect:
Deep-etching saline soil area of the present utility model foundation protection node, makes design and workmen be easy to operation；External protection coating with the laminating of concrete hot melt closely, stops the intrusion of extraneous corrosive medium, can be effectively protected base concrete；Basic asphalt concrete cushion so that sole plate is effectively protected；In the technical solution of the utility model, safeguard procedures can be greatly improved concrete degree of compaction, outer protection can effectively stop the intrusion of outside etching medium, the guard technology of this combination of inner and outside, safe, economical, concrete durability can be strengthened conscientiously, make Power Plant Buildings thing basis normal operation within design period, it is ensured that the operation safety of power plant.
Accompanying drawing explanation
Fig. 1 is positive elevational schematic view of the present utility model；
Wherein: 1 basis；2 overcoats；3 bottom bed courses；4 structural columns.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail:
Referring to Fig. 1, a kind of deep-etching saline soil area of the present utility model foundation protection node, including the overcoat 2 on basis 1 and parcel basis 1；The described bottom of basic 1 is provided with bed course 3, is fixed with structural column 4 in described basic 1.
Further, basis 1 and structural column 4 all adopt reinforced concrete structure, and concrete grade, be more than or equal to C40, selects tricalcium aluminate (C3A) content Portland cement less than or equal to 5% or portland slag cement；Maximum water-cement ratio is 0.4, and mixing water adopts drinking water；Minimum cement dosage is 340/m3；Maximum chloride ion content is 0.1%；Maximum alkali content is 3/m3；Concrete admixture adopts airtight dose of the resisting corrosion effectively of cement consumption 2% and the anticorrosive corrosion inhibitor of 3%.The both sides on basis are hierarchic structure, and basic 1 end face, negative and positive angle, side all do circular arc and process.Basis 1 end face, negative and positive angle, side place set up defences sheath 2; overcoat 2 is followed successively by from the inside to the outside: be coated with adhesive bitument primer twice; smear twice bituminous grout (thickness 3～5mm) again; the molten method of reusable heat pastes 4mm thickness modified asphalt waterproof coiled material " SBS "; the indoor bag of overcoat 2 is to terrace place; outdoor bag is to aproll place, and 20mm thickness 1:3 cement mortar protective course is smeared on surface.
Further, bottom bed course 3 adopts bituminous concrete bed course thickness 150mm, and wherein: grain formula bituminous concrete in 130mm thickness, 20mm thickness asphalt mortar, bituminous mortar top screed-coat, based on the bed course width of bottom, 1 main body extends 150mm to outer.Bottom bed course 3 upper surface lays 4mm thickness modified asphalt waterproof coiled material " SBS ", pastes with basic 1 side modified asphalt waterproof coiled material " SBS " overlap joint and closes up, pastes width be more than or equal to 100mm.
