Abstract
There is a prefabricated direct-buried thermal insulation pipe for waterproof construction, belong to insulation pipe technical field, entering thermal insulation layer for preventing moisture.Its technological scheme is: which increase waterproof closure plate, waterproof closure plate is annular slab, waterproof closure plate is arranged on the two ends of thermal insulation layer respectively, the outer peripheral surface of waterproof closure plate and the inwall compact siro spinning technology of outer pillar, the bore area of waterproof closure plate and the outer wall compact siro spinning technology of working steel tube.The utility model is by the waterproof closure plate shutoff of thermal insulation layer two ends, waterproof closure plate adopts the high temperature resistant hard material of stupalith or steel material or other to make, waterproof closure plate and adopt water-tight corrosion-proof to seal between working steel tube and outer pillar, thermal insulation layer can be entered by effectively anti-sealing by the two ends of thermal insulation layer, avoid thermal insulation layer to subside and cause heat insulation effect to decline, can prevent the tube wall of the moisture in thermal insulation layer to thermal insulation pipe from causing corrosion simultaneously, ensure the working life of thermal insulation pipe, reduce maintenance cost, servicing time and workload.
Description
Technical field
The utility model relates to a kind of prefabricated direct-buried thermal insulation pipe for liquid, gas, belongs to insulation pipe technical field.
Background technique
Prefabricated direct-buried thermal insulation pipe is widely used in the transmission pipeline network of liquid, gas, has that to reduce engineering cost, heat loss low, energy saving, anticorrosion, good insulation preformance, long service life, occupation of land less, the advantage such as favorable environment protection.In use easily there are some defects in the thermal insulation layer of now widely used prefabricated direct-buried thermal insulation pipe, the mainly uneven cavity of causing of polyurethane foam, or the cavity that the distortion adopting the thermal insulation layer of inorganic material to make moist appearance causes, these cavities and inorganic heat insulation material itself all easily cause retaining, make moist.Though require before construction first to take strict dewatering measure, but practice of construction or when depositing, being often difficult to guarantee does not have moisture to enter thermal insulating material, causes thermal insulation layer retaining, makes moist, and then causes thermal insulating material to subside, and heat insulation effect reduces.Meanwhile, the moisture contained in thermal insulation layer can make the tube wall of thermal insulation pipe produce corrosion, and had a strong impact on the working life of thermal insulation pipe, the thermal insulation pipe upgrading corrosion substantially increases maintenance cost, too increases servicing time and workload, improves enterprise's cost of production.Therefore how to prevent prefabricated direct-buried thermal insulation pipe from being problem in the urgent need to address depositing, constructing and having in using process moisture to carry out thermal insulation layer.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of prefabricated direct-buried thermal insulation pipe with waterproof construction, this thermal insulation pipe can prevent prefabricated direct-buried thermal insulation pipe from carrying out thermal insulation layer depositing, construct and have in using process moisture, ensure the heat insulation effect of thermal insulation pipe, extend the working life of thermal insulation pipe.
The technological scheme solved the problems of the technologies described above is:
A kind of prefabricated direct-buried thermal insulation pipe with waterproof construction, it comprises working steel tube, thermal insulation layer, outer pillar, thermal insulation layer is filled between working steel tube and outer pillar, its improvements are, it also increases waterproof closure plate, waterproof closure plate is annular slab, waterproof closure plate is arranged on the two ends of thermal insulation layer respectively, the outer circumference diameter of waterproof closure plate and the internal diameter of outer pillar match, the diameter of bore of waterproof closure plate and the external diameter of working steel tube match, the outer peripheral surface of waterproof closure plate and the inwall compact siro spinning technology of outer pillar, the bore area of waterproof closure plate and the outer wall compact siro spinning technology of working steel tube.
The above-mentioned prefabricated direct-buried thermal insulation pipe with waterproof construction, described waterproof closure plate adopts stupalith or steel material or other exotic materials, waterproof closure plate itself carries out waterproof and preservative treatment, be tightly connected by water tight packing and anticorrosive packing between the outer peripheral surface of waterproof closure plate and the inwall of outer pillar, be tightly connected by water tight packing and anticorrosive packing between the bore area of waterproof closure plate and the outer wall of working steel tube.
The beneficial effects of the utility model are:
The utility model is by the waterproof closure plate shutoff of thermal insulation layer two ends, waterproof closure plate adopts the high temperature resistant hard material of stupalith or steel material or other to make, waterproof closure plate and adopt water-tight corrosion-proof to seal between working steel tube and outer pillar, thermal insulation layer can be entered by effectively anti-sealing by the two ends of thermal insulation layer, avoid thermal insulation layer to subside and cause heat insulation effect to decline, can prevent the tube wall of the moisture in thermal insulation layer to thermal insulation pipe from causing corrosion simultaneously, ensure the working life of thermal insulation pipe, reduce maintenance cost, servicing time and workload.The utility model structure is simple, waterproofing effect is reliable, easy to install. the problem that the heat insulation layer structure solving conventional vacuum pipe makes moist, especially has a significant effect to the insulating structure containing inorganic heat insulation material.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, mark is as follows: working steel tube 1, thermal insulation layer 2, outer pillar 3, waterproof closure plate 4.
Embodiment
The utility model comprises working steel tube 1, thermal insulation layer 2, outer pillar 3, waterproof closure plate 4.
Show in figure, the something in common of the utility model and conventional construction is, filling heat insulating wall 2 between working steel tube 1 and outer pillar 3 to reach heat insulation effect, and is add waterproof closure plate 4 respectively at the two ends of thermal insulation layer 2 to the improvements of conventional construction.
Show in figure, waterproof closure plate 4 is annular slab, the outer circumference diameter of waterproof closure plate 4 and the internal diameter of outer pillar 3 match, the diameter of bore of waterproof closure plate 4 and the external diameter of working steel tube 11 match, waterproof closure plate 4 gets lodged in the two ends of thermal insulation layer 2, the outer peripheral surface of waterproof closure plate 4 and the inwall compact siro spinning technology of outer pillar 3, the bore area of waterproof closure plate 4 and the outer wall compact siro spinning technology of working steel tube.
Waterproof closure plate 4 adopts stupalith or steel material or other exotic materials, and material itself, through waterproof and preservative treatment, has good water-proof performance.Waterproof closure plate 4 gets lodged in the two ends of thermal insulation layer 2, and extraneous moisture itself does not enter thermal insulation layer 2 by water-proof plug plate 4, can only enter from the joint gap of waterproof closure plate 4 and working steel tube 1 and outer pillar 3.In order to prevent moisture from entering from these gaps, be connected and sealed by water tight packing and anticorrosive packing between the outer peripheral surface of waterproof closure plate 4 and the inwall of outer pillar 3, between the bore area of waterproof closure plate 4 and the outer wall of working steel tube 1.
