Description
Technical field
The utility model is related to fixed pipe fittings, especially provide a kind of direct-burried prefabricated thermal insulation and fix pipe fitting.
Background technology
The effect of fixed pipe fitting is exactly a certain node location of directly-buried thermal insulation pipes system to be made to exist using concrete anchor block
It is fixed in soil, and thrust Fx, Fy, Fz from three directions of directly buried pipeline system are born together with concrete anchor block.It passes
The fixed pipe fitting of system adopts Northern Europe technology, i.e., thrust disc as shown in Figs. 1-3 fixes pipe fitting, it is by working steel tube 1, thrust disc 2
It is formed with stiffener plate 3, steel outer casing 4 and thermal insulation material 5.Thrust Fx, Fy, Fz from work steel pipe are by fixing pipe fitting in figure
Thrust disc 2 is transferred to armored concrete anchor block 6, and back pressure, earth bearing strength between armored concrete anchor block 6 and soil 7 and
Frictional force can balance thrust Fx, Fy, Fz from working steel tube, therefore the relative position of the node and soil 6 is fixed.With
The increasingly increasing of work caliber, pumped (conveying) medium pressure is continuously improved, and the thrust from working steel tube 1 is also more and more big by (~500
Ton), the drawbacks of thrust disc fixes pipe fitting, is also more apparent, and main problem is as follows：
1st, 3~4 times of thrust disc 2 and 1 Wall-Thickness Difference of working steel tube do not wait walls welding to cause 1 intensity of working steel tube insufficient；
2nd, it fixes pipe fitting axial direction arrangement of reinforcement along thrust disc by thrust disc 2 to be separated, leads to 6 larger of armored concrete anchor block
At least 50%；
3rd, thrust disc 2 is welded with conveying the working steel tube 1 of thermal medium, and heat is directly conducted by thrust disc, not only generates heat
Loss, more seriously since 2 surface heat accumulation of thrust disc causes 2 surface temperature rise of thrust disc to~90 DEG C, and concrete
Long-term heatproof ≯ 80 DEG C.This will lead to normal concrete hydraulic performance decline；
4th, thrust disc 2 is annular medium plate not only high material consumption and utilization rate is low；
5th, thermal insulation material partition is made its both sides insulation construction discontinuous by thrust disc 2, so as to reduce insulation construction can
By property.
Therefore, there is an urgent need to a kind of direct-burried prefabricated thermal insulation fixation pipe fittings of function admirable by people.
Utility model content
The purpose of this utility model is to provide a kind of direct-burried prefabricated thermal insulations to fix pipe fitting, can effectively solve above-mentioned ask
Topic.
The technical solution of the utility model is：A kind of direct-burried prefabricated thermal insulation fixes pipe fitting, including：Working steel tube 1, outer shield steel
Pipe 4, thermal insulation material 5, power transmission gusset 8, WELDING STUDS 9；The steel outer casing 4 is set on outside working steel tube 1, the working steel tube 1
Overall structure, the working steel tube 1 are welded as by the uniformly distributed rectangle power transmission gusset 8 of polylith circumferential direction between the two with steel outer casing 4
Thermal insulation material 5 is filled between steel outer casing 4, the WELDING STUDS being made of several WELDING STUDSs 9 is welded on the steel outer casing 4
Group.
Preferably, 8 quantity of power transmission gusset is 3~20 pieces.
Preferably, the WELDING STUDS group is made of the uniformly distributed WELDING STUDS 9 of multiple rows of circumferential direction.
Preferably, the quantity of the WELDING STUDS 9 is 3~200.
Preferably, the distance between adjacent WELDING STUDS 9 is not less than 100mm.
The utility model has following beneficial effect：
1st, structure entirety uniform force, and with concrete anchor block is molten is integrated；
2nd, concrete anchor block on pipeline axial direction can continuous reinforcement, reduce concrete anchor block appearance and size；
3rd, the heat of working steel tube outflow is evenly distributed on each WELDING STUDS, and the concentration for avoiding temperature is transmitted,
It ensure that concrete anchor block performance reliably and with long-term；
4th, specific thrust disk saves steel 90%, stock utilization 97.5%；
5th, working steel tube, steel outer casing are not influenced the company of thermal insulation material by circumferential uniformly distributed rectangle power transmission gusset therebetween
Continuous arrangement, ensure that the reliability of insulation construction.

Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and examples.
As Figure 4-Figure 6, a kind of direct-burried prefabricated thermal insulation fixes pipe fitting, including：Working steel tube 1, steel outer casing 4, thermal insulating material
Material 5, power transmission gusset 8, WELDING STUDS 9；Steel outer casing 4 is set on outside working steel tube 1, working steel tube 1 and steel outer casing 4 by the two it
Between the uniformly distributed rectangle power transmission gusset 8 of polylith circumferential direction be welded as overall structure, and wall thickness is adapted between them, 1 He of working steel tube
Thermal insulation material 5 is filled between steel outer casing 4, the WELDING STUDS group being made of several WELDING STUDSs 9 is welded on steel outer casing 4.
