Description
Technical field
The present invention relates to cross over line 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 above.
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 be exactly in order to solve deficiencies of the prior art, provide thermal pipe be laid with when fuel gas conduit above
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 above 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；
Determine the specific location of burning line.It is excavated within the scope of 3 meters of pipeline and uses hand excavation, it is careful, and reinforce
Observation, in order to avoid damage burning line.
Step 2: wood is arranged in burning line lower part after digging out the groove that heating pipeline is installed in burning line lower part enough
Matter gusseted；
Step 3: smooth burning line lower channel, backfill 200mm gravel does trench liner, is then laid with heating pipeline；
Reduce damage of the channel bottom of out-of-flatness to heating pipeline.
Step 4: brick wall supporting is arranged in burning line two sides, brick wall trench liner as described in step 3 is laid with upwards,
Level is higher than burning line tube top on brick wall；Brick wall plays the role of protecting burning line, supports the soil layer from surrounding
Pressure, while cut down road surface transmitting come pressure.
Step 5: back-filling in layers gravel, gravel is backfilled to higher than brick wall top, and is tamped with water pouring；Gravel backfill is supreme
It is tamped in brick wall top, and with water pouring；This mode can make sandy gravel stratum bury brick wall, so that the stress from ground point
It dissipates, protects the stability of burning line and heating pipeline.
Step 6: disposing 30mm thick steel plate in the upper plane that step 5 generates；
C30 concrete layer is filled out Step 7: filling on the steel plate of step 6, then uses blacktop capping；
Brick wall is parallel to burning line in the step 4, and the brick wall is away from nearest burning line axle center distance
300mm, brick wall are risen in burning line tube top 300mm, and the brick wall is 37 brick walls.
Concrete layer described in the step seven is 600mm.
Gravel in the step 5 is backfilled to higher than brick wall top 100mm.This height be be laid with when be higher by 100mm, and
It is not that the height after tamping is poured with water.In practice of construction, it is basic consistent with brick wall height that rear sandy gravel stratum is tamped with water pouring.
The protection structure used in the guard method that fuel gas conduit is intersected above when thermal pipe is laid with, including the ditch after excavating
The trench liner of trench bottom, the trench liner top are equipped with heating pipeline, are equipped with nesting on the trench liner
The brick wall of heating pipeline, the brick wall are two stifled, and two stifled brick walls are located at burning line two sides in parallel, on the stifled brick wall of described two
Plane is higher by burning line tube top；
Outside is equipped with sandy gravel stratum in the brick wall, and plane is stamped steel plate, the steel plate top on the brick wall
Filling is filled with C30 concrete layer, and the concrete layer top is equipped 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, trench liner reduces damage of the channel bottom of out-of-flatness to heating pipeline.
3, gravel is backfilled to higher than brick wall top, and is tamped with water pouring；This mode can make sandy gravel stratum cover brick wall
It buries, so that the stress from ground disperses, protects the stability of burning line and heating pipeline.
4, the effect of concrete, steel plate is also supporting role, ensure that heating pipeline not by the pressure from road surface.
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.
