Abstract
A composite material heat-insulating pipeline mainly comprises a perlite shell 1, foamed plastic 2, an outer waterproof layer 3 and a pipeline 4. The utility model discloses a pearlite has replaced the very high heat preservation foamed plastic of price, has reduced the cost, keeps warm moreover, waterproof effect homoenergetic reaches the design requirement, is the underground direct-burried insulating tube of an ideal.
Description
The utility model belongs to constructional materials, is a kind of direct buried utilidor.
The thermal-insulating pipe case of known direct buried pipeline, there is the high molecular polymer (as polyurethane foam plastic) of direct foaming to make, though heat insulation effect is fine, but cost is too high, also have a class thermal-insulating pipe case to adopt pitch and inorganic heat insulation material to be mixed and made into, but after pipeline was heated, the pitch at duct wall place dissolved, and pipeline and insulation layer are thrown off.
The purpose of this utility model is to provide a kind of insulation, water resistance good, the buried utilidor that construction costs is low.
Solution of the present utility model is to adopt organic and inorganic heat insulating material, makes composite thermal pipeline.
Below in conjunction with accompanying drawing the utility model is specified:
Fig. 1 is the utility model partial sectional view;
Fig. 2 is the utility model sectional view;
Fig. 3 is a pearl shell schematic diagram.
The utility model is by pearl shell 1, foamed plastics 2, and exterior waterproof coating 3 and pipeline 4 consist of, wherein pearl shell 1 is semicircle shell, boss 5 is arranged on the fore-and-aft plane, and its inside radius is than the big 10～20mm of pipeline 4 outer radius, and length is 300～600mm. Between the pearl shell 1, all be full of foamed plastics 2 between pearl shell 1 and the pipeline 4, exterior waterproof coating 3 is at outermost layer. Wherein foamed plastics 2 can be polyurethane foam plastic, and exterior waterproof coating 3 is waterproof material.
The utility model is simple in structure, and cost is low, and thermal-insulating waterproof is effective, can save a large amount of organic insulation materials.
Claims (2)
