Abstract
The utility model relates to an anticorrosive lining for a steel water pipe, which is composed of a compound structure of three-layer. The utility model comprises an adhesive transition layer, a water-resisting insulation layer and a water-resisting protective layer. The adhesive transition layer is coagulated by cement, sand and a compound colloid after mixed with water. The water-resisting insulation layer is a single cement layer, and the water-resisting protective layer is a Portland cement mortar. When lining is carried out, the lining structure of the utility model can avoid the phenomena in which the top surface crashes in a large area, and expands in the middle and cracks.
Description
The utility model belongs to the design of conduit pipe inner wall anti-corrosive, and it is anticorrosion particularly to execute lining by inside.
At present, generally believe both at home and abroad that adopting cement-mortar lining is to solve corrosion-resistant ideal measure in the metal conduit pipe, but in practice, adopt the conventional cement mortar lining to be used for the heavy caliber water conveyance steel tube and can not obtain antiseptic effect preferably.Reason is that the easy occurrence of large-area of slush lining of managing the top is fallen, hollowing and cracking phenomena.No matter employing is mechanical or manually executing lining all can not solve the difficult problem that this jeopardizes construction quality.
The purpose of the utility model design provides a kind of new cement-mortar lining structure, makes it closely to be attached at large-scale water conveyance steel tube inwall, and the top lining does not fall, hollowing and cracking, and another purpose of the design is to improve the sealability of lining.
The lining structure of the utility model design is a three-layer composite water silt particle slurry lining structure.Comprise the adhesive transition layer that adheres to inner tube wall, invest water proof isolation layer on the transition layer and the water resisting protection layer outside isolation layer.Adhesive transition layer is condensed and is formed by cement, sand, aggregation colloid water mix.The aggregation colloid that uses can be a polyvinyl acetate emulsion, Pioloform, polyvinyl acetal or 107 glue.Quality requirement to material is: cement selects for use early strength to increase slow cement, and for example 400
#Slag cement or pozzolan cement.Sand is selected cleaning for use and scleroid extra large sand.0.6～2 millimeter of particle diameter, clay content is no more than 1%.The viscosity of aggregation colloid is more than 5000 centipoises.Wet concentration is with the common tap water of drinking.The water proof isolation layer is plain cement layer.The water resisting protection surface layer is the conventional cement mortar layer.
The design's characteristics are to make the single layer structure that lining replaces slush with three layers of lamination layer structure.Three-decker respectively has effect alone, and adhesive transition layer is bonded on the steel pipe inwall composite structure lining firmly, and the water proof isolation layer plays water proof insulation, sealing corrosion, and the water resisting protection surface layer plays the protective action that anti-current wash away.The design's advantage be to execute when lining can generator tube roof liner layer large size do not fall, hollowing and cracking phenomena, another advantage of the design is owing to use aggregation colloid, also improved the sealability of lining significantly, under the situation that does not increase cement consumption, the lining grade of mortar has been improved.
The design's embodiment as shown in drawings.
Illustrate:
Water conveyance steel tube wall A, adhesive transition layer 1, water proof isolation layer 2, water resisting protection layer 3.
In the practice of construction of large-scale water conveyance steel tube, adhesive transition layer thickness can be 3～5 millimeters, preferably 4 millimeters.2～2.5 millimeters of water proof thickness of insulating layer, lining is smeared at twice.4～6 millimeters of water resisting protection surface thicknesses, preferably 5 millimeters.
Claims (2)
1, a kind of water conveyance steel tube slush corrosion protective lining structure is characterized in that lining structure is three layers: adhesive transition layer, water proof isolation layer and water resisting protection layer; Adhesive transition layer is by cement, sand, and aggregation colloid water mix condenses and forms, and aggregation colloid can be used polyvinyl acetate emulsion, Pioloform, polyvinyl acetal or 107 glue; The water proof isolation layer is plain cement layer; The water resisting protection surface layer is the conventional cement mortar layer.
2, according to the described lining structure of claim 1, it is characterized in that adhesive transition layer thickness is 3～5 millimeters, preferably 4 millimeters, 2～2.5 millimeters of water proof thickness of insulating layer, water resisting protection surface thickness are 4～6 millimeters, best 5 millimeters.
