Abstract
The invention discloses a waterproof and anti-corrosion prestressed hollow pipe with a coating and relates to the technical field of buildings. The waterproof and anti-corrosion prestressed hollow pipe with the coating comprises a pile body, wherein a liquid rubber spray coating material coating and a compound protection layer are sequentially sprayed on the pile body of the waterproof and anti-corrosion prestressed hollow pipe with the coating from inside to outside, and the liquid rubber spray coating material coating is sprayed on the inner wall surface of the pile body. The waterproof and anti-corrosion prestressed hollow pipe with the coating, disclosed by the invention, is simple in structure, the liquid rubber spray coating material coating is sprayed on the surface layer of the pile body of the prestressed pile, and after a film is formed, the film is dried under natural conditions and a complete and seamless adhesive film is formed, so that the waterproof and anti-corrosion prestressed hollow pipe with the coating has great chemical resistance, strong resistance against strong acid, alkali and salts and very high anti-puncture performance.
Description
Technical field
The present invention relates to technical field of buildings, especially a kind of water-tight corrosion-proof pre-stress hollow stake of coating.
Background technology
The building foundation is the pith of whole building building, and the basis generally is positioned at undergroundly, receives erosions such as earth, moisture and chemical substance for a long time; Waterproof or antiseptic property directly affect the application life of building foundation; Like present application prestressed pile comparatively widely, all be reinforced concrete structure generally, directly apply to underground support of buildings; Though steel concrete has certain waterproof and antiseptic property; But there is certain density in it, and the long-term water erosion and the erosion of some chemical substances can influence the intensity of pile body, thereby has increased the maintenance cost of building.
Summary of the invention
The present invention provides a kind of simple in structure in order to solve the problems referred to above that exist in the prior art, and waterproof anti-corrosion performance is excellent, the water-tight corrosion-proof pre-stress hollow stake of the coating of long service life.
The present invention solves the technical scheme that the prior art problem adopted: a kind of water-tight corrosion-proof pre-stress hollow stake of coating; Comprise pile body, it is characterized in that: the pile body of the water-tight corrosion-proof pre-stress hollow stake of said coating outwards is coated with liquid rubber spray-coating material coating and composite protection layer successively.The internal face of said pile body is coated with the liquid rubber spray-coating material coating.Said liquid rubber spray-coating material coating is 1-3 ㎜.
A kind of water-tight corrosion-proof pre-stress hollow stake of coating in addition comprises that the internal face of the said pile body of pile body is coated with the liquid rubber spray-coating material coating.Said liquid rubber spray-coating material coating is 1-3 ㎜.
Said liquid rubber spray-coating material is divided into A, two kinds of components of B; Said A component is an anion liquid body rubber asphalt emulsion; Said B component is a coagulant solution; Said A component is represented with mass percent, and liquid rubber asphalt emulsion weight solid content is 50-75%, wherein, rubber latex 1-65%, asphalt emulsion 20-97%, anionic dispersing agents 0.0025-2.5%, anion surfactant 0.0025-4%; Said B component is represented with mass percent, is 3-18% the aqueous solution by calcium chloride, the formulated concentration of compound ferro-aluminum mixed with polymers; The spraying Capacity Ratio of said liquid rubber spray-coating material B component and A component is 1/15-1/3.5.
Spraying coating process is for to be respectively charged into the A for preparing, B component in the proportion container separately; Under the promotion of dynamical system, A component and B component run to spray gun separately respectively through two pipelines, and two muzzle slope inwardly during spraying; Spray angle is aimed at the same district of the object basal plane face that needs spraying simultaneously; The moment of material ejection forms atomization process, and two components are fully mixed before arriving basal plane or when arriving basal plane, film thereby form more uniform rubber asphalt.Two components are 350-600mm in the joint distance of mixing the spraying face of arrival.
The invention has the beneficial effects as follows: the present invention is simple in structure; In the pile body top layer of prestressed pile spraying liquid rubber spray-coating material coating; Dry under field conditions (factors) and form complete seamless glued membrane after the film forming, it is strong that it has a powerful chemical resistance, anti-strong acid, alkali, salt characteristic, and very high anti-puncture resistance is arranged; Film forming thickness＞2 ㎜ have good self-healing function, and it is less influenced by the underground foundation soil property; Do not scurry water between liquid rubber spray-coating material coating and substrate pile body, really reach the skin-type waterproof requirement, prevent the crackle crack on building top layer; Efflorescence ashing, decortication are peeled off, the effect of weather natural aging, to sum up; Have stronger waterproof and antiseptic property, long service life.
