Description
Technical field
The present invention relates to cross pipeline protection technique fields when heating pipeline construction, fire when specifically thermal pipe is laid with
The guard method and its protection structure that tracheae intersects in lower section.
Background technique
Major part urban district central heating now starts from eighties of last century, and when design lacks long-term plan, along with the time is remote
Seriously corroded, heating season problem take place frequently.Heating network transformation needs take leave of " patch maintenance ", be not where be broken repair where, and
It is to redesign transformation, it is long-standing is expected to the heating of solution old residential area.And most of problem is what part was used for heat unit
Boiler is relatively backward, power output is not high；Complete auxiliaries equipment and pipe network are long neglected and in disrepair, and operational efficiency is relatively low.
Simultaneously because urban construction needs, the various pipelines of different time laying can be encountered when pipe network upgrading
And route, higher risk is exactly burning line, and burning line migration is lost more than gain, combustion gas route and heating pipeline phase
It hands over.Excavate to change by design requirement and fill out miscellaneous fill and plain fill and backfill qualified gravel, in order to guarantee burning line and construction site
Safety, it is necessary to which protective treatment is carried out to natural gas pipeline.
Summary of the invention
The present invention is exactly to solve deficiencies of the prior art, and fuel gas conduit is in lower section when providing thermal pipe laying
The guard method and its protection structure of intersection.Entire work progress and structural defence burning line are injury-free, use simultaneously
The reasonable Arrangements such as brick wall, sandy gravel stratum ensure that burning line not by external pressure.
The technical scheme adopted by the invention to solve the technical problem is that:
The guard method that intersects in lower section of fuel gas conduit when thermal pipe is laid with, the guard method the following steps are included:
Step 1: verifying burning line position, hand excavation is used in 3 meters of burning line；
Before construction, site operation responsible person contacts with combustion gas unit, verifies the position of burning line, is mentioned according to right gas unit
The burning line position of confession determines buried depth of pipeline, careful using hand excavation, and reinforces observing, in order to avoid damage natural gas
Pipeline.After verifying underground utilities, mark.Isolation will be gone along with sb. to guard him with warning rope within the scope of 5.0 meters of pipeline, and is nearby arranged bright
Aobvious sign board, teams and groups of organizing construction carry out pipeline and detect the meeting of telling somebody what one's real intentions are.
Step 2: wooden gusseted is arranged in burning line lower part after digging out burning line；
It is excavated within the scope of 3 meters of burning line and uses hand excavation, it is careful, and reinforce observing, in order to avoid damage natural gas
Pipeline.Pipeline wooden gusseted arranged below, Suspended Pipelines sink after excavation to prevent pipeline.
Step 3: brick wall supporting is arranged in burning line two sides, brick wall is risen in burning line tube top 100mm；Brick wall is flat
Row is 300mm away from nearest burning line axle center distance in burning line, the brick wall.
Step 4: back-filling in layers gravel, gravel is backfilled to burning line top 120mm, and is tamped with water pouring；This mode
The sandy gravel stratum of step 4 can be made to bury brick wall, so that there is certain thickness on the heating pipeline and brick wall of next step between plane
The gravel of degree ensure that the stability of heating pipeline.In step 4, described 120mm is before being poured with water.Sand after pouring
Plane is basic on gravel bed and brick wall either flush.
Step 5: heating pipeline is installed at the top of brick wall, and be backfilled in the middle part of heating pipeline with gravel, backfill with a thickness of
800mm is tamped after backfill with water pouring；Here the heating pipeline diameter used is 1600mm.
It is assured Step 6: being filled on the sandy gravel stratum of step 5 and filling out C30 concrete layer, concreting, will on sandy gravel stratum
Heating pipeline cladding, plays a supporting role simultaneously, eliminates the stress of heating pipeline.Steel plate, the effect of steel plate are covered above tube top
It is also supporting role, ensure that heating pipeline not by the pressure from road surface, steel plate top backfills 12 reinforced concrete floor of φ, so
Blacktop capping is used afterwards.
Steel plate thickness in the step 6 is 30mm, and 12 reinforced concrete floor of φ is with a thickness of 200mm.
The protection structure that fuel gas conduit uses in the guard method that lower section intersects when the thermal pipe is laid with, characterized in that
Including brick wall, the brick wall is two stifled, and two stifled brick walls are located at burning line two sides in parallel, and plane is high on the stifled brick wall of described two
Burning line tube top out；
Brick wall plays the role of protecting burning line, supports the pressure of the soil layer from surrounding, while cutting down heating pipeline
And the pressure that road surface transmitting comes.
Outside is equipped with sandy gravel stratum in the brick wall, and heating pipeline, the sandy gravel stratum are provided on the brick wall
Upper plane is concordant with heating pipeline axis, and the sandy gravel stratum top is equipped with concrete layer, and the concrete layer coats heating power
Pipeline, the concrete layer top are equipped with steel plate, are equipped with reinforced concrete floor, the reinforced concrete above the steel plate
Soil layer top is covered with blacktop.
The beneficial effects of the present invention are:
1, entire work progress and structural defence burning line are injury-free while reasonable using brick wall, sandy gravel stratum etc.
Arrangement ensure that burning line not by external pressure.
2, gravel is backfilled to combustion gas tube top 120mm, and is tamped with water pouring；This mode can make the gravel of step 4
Layer buries brick wall, so that there is certain thickness gravel on the heating pipeline and brick wall of next step between plane, ensure that heating power
The stability of pipeline.
3, concreting coats heating pipeline on sandy gravel stratum, plays a supporting role simultaneously, eliminates heating pipeline
Stress.
4, the effect of reinforced concrete floor, steel plate is also supporting role, ensure that heating pipeline not by the pressure from road surface
Power.
5, brick wall plays the role of protecting burning line, supports the pressure of the soil layer from surrounding, while cutting down thermal pipe
The pressure that line and road surface transmitting come.
