Abstract
The utility model discloses a protecting device of a buried gas pipeline. The protecting device of the buried gas pipeline comprises a bottom groove, a pinch plate and strip-shaped flanges. The bottom groove is identical to the pinch plate in structure. The longitudinal section of the bottom groove and the longitudinal section of the pinch plate are both of a semicircular shape. The strip-shaped flanges are horizontally fixed at two sides of the central line of the bottom groove and the center line of the pinch plate in a welding mode. Bolt holes are evenly distributed on each strip-shaped flange. The bottom groove coats the lower half portion of the buried gas pipeline. The pinch plate coats the upper half portion of the buried gas pipeline. The bottom groove, the buried gas pipeline and the pinch plate are fixed through bolts. The protecting device of the buried gas pipeline has the advantages of being simple in manufacture, convenient to operate, safe, reliable, free of influence on the use of the gas pipeline and the in-time construction of the gas pipeline, low in engineering investment and capable of effectively reducing construction cost.
Description
Technical field
The utility model relates to a kind of gas pipe line protective gear, the protective gear that buries the ground gas pipe line that uses when especially relating to a kind of road construction.
Background technique
If run into the gas pipe line that buries ground during iron and steel plant area constructing road or enlarging construction at present, because the gas pipe line limit exists the construction welding of can not getting angry to wait restrictive condition, usually the mode that adopts is that a newly-built gas pipe line is relocated existing pipeline, and newly-built pipework input is very big, and for the iron and steel ordinary production, usually adopt and carry out gas pipe line relocate when Iron And Steel Plant's overhaul, the cycle is longer, and this mode is also bigger to the influence of road construction duration.
The model utility content
The purpose of this utility model is at the deficiencies in the prior art, and provides a kind of making simple, and is easy to operate, safe and reliable, do not influence gas pipe line to use and road construction, and engineering drops into the little protective gear that buries the ground gas pipe line.
The protective gear that buries the ground gas pipe line of the present utility model; comprise kerve, buckle, bar shaped flange; described kerve is identical with buckle structure; the equal semicircular in shape in longitudinal cross-section; described bar shaped flange level is weldingly fixed on the both sides of kerve and buckle center line, is evenly equipped with bolt hole on the described bar shaped flange, and described kerve is wrapped in the lower half portion of burying the ground gas pipe line; buckle is wrapped in the upper half part of burying the ground gas pipe line, kerve, buries ground gas pipe line and buckle and passes through bolt.Described kerve and buckle inner and outer surface all scribble anticorrosive paint.
The beneficial effects of the utility model are: (1) makes simple, and is easy to operate, safe and reliable; (2) do not influence gas pipe line use and road and construct as scheduled, engineering drops into little, effectively reduces construction cost.

Fig. 2 is a plan view of the present utility model.
Fig. 3 is a method of construction schematic representation of the present utility model.
Fig. 4 is a section construction schematic representation of the present utility model.
Among the figure: kerve 1, buckle 2, bolt 3, bar shaped flange 4, bolt hole 5, bury ground gas pipe line 6, concrete floor 7, bed course 8, protective layer 9, roadbed 10, road surface 11.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
In the drawings, the protective gear that buries the ground gas pipe line of the present utility model mainly by kerve 1, buckle 2, bolt 3, bar shaped flange 4, bolt hole 5, bury ground gas pipe line 6, concrete floor 7, bed course 8, protective layer 9, roadbed 10 and road surface 11 and form.
Described kerve 1 is identical with buckle 2 structures, the equal semicircular in shape in longitudinal cross-section, described bar shaped flange 4 levels are weldingly fixed on the both sides of kerve 1 and buckle 2 center lines, be evenly equipped with bolt hole 5 on the described bar shaped flange 4, described kerve 1 is wrapped in the lower half portion of burying ground gas pipe line 6, buckle 2 is wrapped in the upper half part of burying ground gas pipe line 6, and described kerve 1, to bury ground gas pipe line 6 and buckle 2 fixing by bolt 3.Described kerve 1 and buckle inner and outer surface all scribble anticorrosive paint.
Adopt section construction to protect continuously when this model utility device is installed, prevent that the existing ground gas pipe line 6 unsettled length of burying are excessive and break.Use earlier manually during construction the earthwork of burying gas pipe line 6 tops, ground is dug out; its top is exposed; the end of back from needing reinforcement placed in the location; bury the ground gas pipe line 6 bottom earthwork with manually excavating with first section earlier; the concreting base plate 7 then; treat after the concrete setting first section kerve 1 to be installed; earlier the axle center clockwise direction of kerve 1 by its arc rotated to an angle during installation; bar shaped flange 4 one sides on the left side are passed from burying space, gas pipe line 6 bottom, ground earlier; again it is counterclockwise rotated the bed course 8 that in kerve 1, returns landfill gas pipe line 6 after the leveling in place; this bed course 8 adopts the medium coarse sand backfill; construct second successively then; the 3rd; the 4th ... concrete floor 7; kerve 1; bed course 8; since first section to the 4th section buckle 2 is installed successively again; this buckle 2 staggers the overlap joint installation to guarantee the global stability of this protective gear with kerve 1; short buckle 2 polishings in two ends, the left and right sides; when buckle 2 is installed be that bolt hole 5 on the bar shaped flange 4 aligns successively with bolt hole 5 on its bar shaped flange 4 and kerve 1; construction bolt 3 is tightened fixing; the protective layer 9 of backfill protective tube after the passed examination; this protective layer adopts the coarse sand backfilling compaction, again roadbed 10 and road surface 11 is carried out the construction of engineering entity.
