Abstract
The utility model discloses an internal-external fixed support of direct-buried thermal insulation heat distribution pipelines, which is composed of an inner fixed support in an annular space between an outer protective pipe and an inner thermal power pipe and an annular plate on a cylinder surface out of the outer protective pipe. The utility model can replace cement concrete supports with large ground occupying and can seal, prevent water and prevent corrosion, the utility model has the advantages of convenient construction, reliable performance, low cost and long service life, and the utility model provides reliable technical assurance for underground push pipe construction and the municipal reform of old cities.
Description
The utility model relates to the inside and outside fixed bearing of a kind of directly buried type insulation heat distribution pipeline, and particularly suitable carries direct buried the laying of heating power pipe of the various calibers of high-temperature steam, high-temperature-hot-water to fix support use, the improvement of metal conduit laying technology.
At present, heat distribution pipeline lays, be energy saving, beautify the environment, mostly adopt direct-buried mode, but the fixed bearing that is provided with in the design of pipe networks pipeline will bear several tons even the big thrust of tons up to a hundred, the past outer fixing bearings that adopt often need the amount of concrete of large volume to make more, take up an area of big, constructional difficulties, and often be difficult to carry out because of underground concealed obstacle in the urban district, old city.
The purpose of this utility model is exactly the defective at above-mentioned existence, and a kind of being easy to that provides constructed, and uses no or little concrete and fixes, and supporting ﹠ stablizing is reliable, the directly buried type insulation heat distribution pipeline external and internal fixation bearing of long service life.
Above-mentioned purpose of the present utility model is by using in the steel of brand-new design, outer support, in the utility model directly buried type insulation heat distribution pipeline that proposes in order to replace concrete bearing, the outer fixing bearing is realized, it is made up of internal fixation bearing and outer fixing bearing, it is characterized in that: above-mentioned internal fixation bearing is disposed in the heat distribution pipeline, annular space position between the outer steel pipe, it is by the band groove annular stop baffle plate on the heating power pipe in being welded on, with also be welded with a band groove annular thrust block plate on the external protective steel tube madial wall of corresponding position, above-mentioned postive stop baffle place, activity is fitted with activity thrust tube sheet in above-mentioned two corresponding groove, also is laid with the dual torus insulating and forms on two side ring surfaces of this activity thrust tube sheet; Above-mentioned outer fixing bearing is made up of an annular slab that is welded on the external protective steel tube external cylindrical surface, and the utility model China and foreign countries fixed bearing annular slab both can be provided with in same vertical guide with the internal fixation bearing; Also can stagger and in same vertical guide, not be provided with.The utility model internal fixation bearing is when installation is provided with, floating tube sheet should leave certain interval during plug-in mounting in two grooves, in service at pipeline like this, because it is uneven in temperature, the large and small difference of inside and outside pipe deformation and issuable distortion is achieved axial displacement, thereby can reduce the stress in the pipe-line system greatly, also just may significantly reduce the suffered supporting force of bearing, can prolong its working life greatly.
Description of drawings:
Fig. 1 is the utility model internal fixation seat structure schematic representation.
Fig. 2 is not provided with structural representation for the utility model outer fixing bearing and internal fixation bearing in same vertical guide.
Fig. 3 is provided with structural representation for the utility model outer fixing bearing and internal fixation bearing in same vertical guide.
The inside and outside fixed bearing of embodiment's directly buried type insulation heat distribution pipeline
Present embodiment is in the utility model directly buried type insulation heat distribution pipeline, the outer fixing bearing is used in carries a kind of embodiment of using in the high temperature steam pipeline, its internal fixation bearing is disposed in the heat distribution pipeline, annular space position between the outer steel pipe, by heating power pipe (1) in being welded on--on band groove annular stop baffle plate (2), on external protective steel tube (6) madial wall of corresponding position, above-mentioned postive stop baffle place, also be welded with a band groove annular thrust block plate (5), activity is fitted with activity thrust tube sheet (3) in above-mentioned two corresponding groove, also is laid with dual torus insulating (4) and forms on two side ring surfaces of this activity thrust tube sheet (3); Its outer fixing bearing is made up of the annular slab (13) that is welded on external protective steel tube (6) external cylindrical surface that is provided with in same vertical guide with the internal fixation bearing; In the present embodiment on the external cylindrical surface of external protective steel tube, also apply anticorrosion, watertightness barrier (12) is housed, in the annular space in pipeline except that the internal fixation bearing, also add urethane plastic thermal insulation layer (7), inorganic material hard heat-insulating layer (8) that can anti-600 ℃ of high temperature, for also adding, the minimizing heat radiation is filled with thermal insulating material (9), in pipeline, also be arranged at intervals with waterproof ring flat-plate (10), duct segments separated do not interlink in order to safe operation, also be provided with 1 humidity discharging pipe (11) in each compartment, in order to detect leakage and the discharge water part in the pipeline.
In the utility model directly buried type insulation heat distribution pipeline, the outer fixing bearing has following advantage: the internal fixation bearing is because in being arranged on, in the annular space of outer tube, its easy construction, waterproof, anticorrosion, sealability is reliable, cost is low, in the internal fixation bearing allows, suitable cold and hot deformational displacement amount is arranged between the Outer Tube, can significantly reduce supporting force, both can guarantee the safe operation of pipe network, can increase its working life again, for providing reliable technique, underground jacking construction guarantees, in, the outer fixing bearing can be saved a large amount of occupation of land spaces than concrete bearing, and its welding position is flexible, advantageously descends dodging of obstacle, use more conveniently, be laying of Urban Buried Pipeline Network, municipal administration transformation to the old town, beautifying the environment provides the reliable technique means.
