Abstract
The invention discloses an anti-freezing method for a buried pipeline. In the method, a heat insulating material is completely or partially filled in a backfill region or a fill region around the pipeline. In the method, the material is completely or partially filled in the backfill region around the pipeline. In the method, the material is completely or partially filled in the fill region around the pipeline. The method has the advantage of greatly saving manual labor and material resources to achieve an anti-freezing effect for the pipeline.
Description
Technical field:
The invention belongs to the engineering field, relate to a kind of buried pipeline means to prevent freezing, especially a kind of around the pipeline back filled region/embankment district partly or entirely adopt the method for backfill thermal insulating material.
Background technique:
Extreme weather conditions phenomenon took place in recent years often; For example on-the-spot actual frost line has often been broken through the frost line data that record is arranged in the past; Cause the pipeline below the former frost line that come into operation and be laid in that freezing phenomenon has still taken place thus; If excavation reduces the pipe laying absolute altitude again once more, will bring great inconvenience and very big manpower, financial resources input; If only change the pipeline earthing into thermal insulating material (like lime-ash), then can save a lot of inputs.
For the buried pipeline engineering of construction not, in order to reduce investment outlay, speed up the work, often hope buried depth of pipeline try one's best more shallow, possibly will make pipe laying more than frost line.
Summary of the invention:
The objective of the invention is to overcome the shortcoming of above-mentioned existing technology; Provide a kind of and freeze dangerous or frozen pipeline for actual the having below the frost line that be laid in; A kind of method that pipeline freezes that prevents of simple possible is proposed; Promptly the method for back filled region/embankment district part employing backfill thermal insulating material (like lime-ash) around pipeline plays the effect that prevents that pipeline from freezing.
The objective of the invention is to solve through following technological scheme:
A kind of buried pipeline means to prevent freezing, said method are that back filled region or the embankment district around pipeline partly or entirely adopts the backfill thermal insulating material.
Said method is all or part of backfill thermal insulating material in back filled region around pipeline.
Said method is all or part of backfill thermal insulating material in embankment district around pipeline.
Said thermal insulating material is a lime-ash.
Advantage of the present invention is: can greatly save the man power and material, play the effect that prevents that pipeline from freezing.
Description of drawings:
Fig. 1 is embodiments of the invention 1 schematic representation;
Fig. 2 is embodiments of the invention 2 schematic representation;
Wherein: 1 is pipeline; 2 is terrace; 3 is thermal insulating material.
Embodiment:
Below in conjunction with accompanying drawing the present invention is done and to describe in further detail:
Referring to Fig. 1 and Fig. 2, buried pipeline means to prevent freezing of the present invention is all or part of backfill thermal insulating material in back filled region or embankment district around pipeline.
Said method is all or part of backfill thermal insulating material in back filled region around pipeline.
Said method is all or part of backfill thermal insulating material in embankment district around pipeline.
Said thermal insulating material is a lime-ash
Need be under the situation more than the frost line for some with pipe laying; A kind of method that pipeline freezes that prevents of simple possible is proposed; Promptly the method for the back filled region/all or part of employing backfill in embankment district thermal insulating material (like lime-ash) around pipeline plays the effect that prevents that pipeline from freezing.
Above content is to combine concrete preferred implementation to further explain that the present invention did; Can not assert that embodiment of the present invention only limits to this; Those of ordinary skill for technical field under the present invention; Under the prerequisite that does not break away from the present invention's design, can also make some simple deduction or replace, all should be regarded as belonging to the present invention and confirm scope of patent protection by claims of being submitted to.
