Description
Technical field
The utility model relates to a kind of directly buried heat distribution pipeline pipe protection structure, belongs to municipal technical field.
Background technique
Heat distribution pipeline is the pipeline of the heat energy such as delivering vapor or superheated water medium, and safety class is higher, belongs to lifeline engineering.At present, domestic heating pipeline is generally along town road direct buried-pipe laying under walk or green belt.In view of current municipal pipeline management comparatively loose and under road pipe laying more, through after a period of time, often occur in transformation or road excavation time, heat distribution pipeline is dug brokenly, cause steam, superheated water to leak, jeopardize municipal traffic and pedestrian's security of the lives and property, cause serious accident.Further, the more difficult discovery of the leakage of under ground piping.Current monitoring and warning means are limited: most adopt the artificial investigation of audition method piecemeal, but heat distribution pipeline is embedded in subsurface, and not only labor intensity is large, investigation efficiency is low and easily occur that leakage point omits situation, and the manpower and materials cost thus dropped into is higher; Or arrange pressure or temperature instrument along the line at pipeline, the change fluctuating range according to system pressure or temperature determines whether to leak, but the high and maintenance management difficulty of these precision instrument costs is large, therefore generally only arranges at key conduit.Under these means or take a lot of work effort, efficiency, or it is high to increase electronic device equipment cost.Above-mentioned deficiency still has the place being worth improving.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency; thering is provided a kind of structure simply and intuitively for municipal directly buried heat distribution pipeline pipe protection structure, is the structure of a kind of directly buried heat distribution pipeline pipe protection cover plate and the heat distribution pipeline applying this cover plate warning and leakage monitoring specifically.
According to the technological scheme that the utility model provides, a kind of directly buried heat distribution pipeline pipe protection structure, road surface is provided with groove, lays heat distribution pipeline, be provided with backfilling material in heat distribution pipeline surrounding in groove, and protective cover is laid in backfilling material upper end.Described protective cover front end is provided with the semicircle the tip of the tongue, and rear end is provided with the semicircle root of the tongue; Protective cover is also provided with pipeline marker.The shape of the described semicircle the tip of the tongue and the semicircle root of the tongue can be engaged.
Described protective cover is positioned at 0.2-0.5m place directly over heat distribution pipeline.
Described backfilling material is poromeric material, is specially coarse sand and/or rubble.Described protective cover is formed by hollow concrete and the material compacting that can vary with temperature color.Described hollow concrete is sand, one or more configurations of rubble, cement, epoxy resin form.
The beneficial effects of the utility model: the utility model structure is simple, warning understands, working service is convenient.Directly over heating pipeline, heat distribution pipeline cover sheet is synchronously set being laid with under road, simple and convenient.Not only can warn thermal pipe to lay position and avoid construction to dig by mistake and damage; and when heat distribution pipeline produces minor leakage; cover sheet directly over the steam leaked is conducted to by the sandstone gap of backfill; cover sheet color can variation with temperature and changing; according to cover sheet change in color, management maintenance personnel just judge whether heating pipeline exists minute leakage intuitively; for the on-call maintenance of pipeline, maintenance provide foundation, occur to prevent large leakage.
Accompanying drawing explanation
Fig. 1 is the utility model structural section figure.
Fig. 2 is protective cover structural representation.
Description of reference numerals: 1, protective cover; 1-1, the semicircle the tip of the tongue; 1-2, the semicircle root of the tongue; 2, heat distribution pipeline; 3, backfilling material; 4, groove.
Embodiment
As shown in Figure 1-2: a kind of directly buried heat distribution pipeline pipe protection structure, road surface is provided with groove 4, lay heat distribution pipeline 2, be provided with backfilling material 3 in heat distribution pipeline 2 surrounding in groove 4, protective cover 1 is laid in backfilling material 3 upper end.Described protective cover 1 front end is provided with semicircle the tip of the tongue 1-1, and rear end is provided with semicircle root of the tongue 1-2; Protective cover 1 is also provided with pipeline marker 5, for warning construction or maintainer.
Protective cover 1 starting point is that semicircle the tip of the tongue 1-1 protrudes, and end is that semicircle root of the tongue 1-2 is recessed, and described the tip of the tongue 1-1 and root of the tongue 1-2 is engaged mutually, and more protection cover plate intensity can prevent from cover sheet from being constructed digging further by mistake.Described protective cover 1 is positioned at 0.2-0.5m place directly over heat distribution pipeline 2.
Described backfilling material 3 is poromeric material, is specially coarse sand and/or rubble.Described protective cover 1 is formed by hollow concrete and the material compacting that can vary with temperature color.Described hollow concrete is sand, one or more configurations of rubble, cement, epoxy resin form.
During the utility model embody rule, first on road, excavate groove 4, then heat distribution pipeline 2 is positioned over the precalculated position in groove 4 and backfill the ventilative backfilling material 3 such as medium coarse sand, graded broken stone and as requested compacting backfill put in place;
Described protective cover 1 is placed in 0.2 ~ 0.5 meter of directly over heat distribution pipeline 2; The semicircle the tip of the tongue 1-1 of last block protection lid 1 and the semicircle root of the tongue 1-2 engaged strengthening cover plate intensity of a rear block protection lid 1;
Finally be backfilling and compacted according to road structure requirement backfilling material 3.
When the intact dirt of heat distribution pipeline is leaked, pipeline configuration layer is complete can realize heat insulation effect, and now tube circumference soil temperature is basically identical, and ambient temperature residing for cover sheet 1 is consistent, and its color is also consistent; Now cover sheet 1 is as heat distribution pipeline 2 witness marker, prevents construction and excavation from destroying heat distribution pipeline 2.When minor leakage occurs heat distribution pipeline in running 2; superheated water in pipeline or steam leakage; the steam leaked conducts to cover sheet 3 by the gap of backfilling material 3 rises; cause leakage point peripheral temperature higher than all the other pipeline section peripheral temperature; thus temperature variant cover sheet 1 color above breakthrough is changed; can embody warning breakthrough intuitively, thus the timely pipe-repairing of prompting maintainer avoids breakthrough expansion to cause security incident.
