Abstract
The utility model provides pipeline corrosion protection device at a kind of deep fat buried pipeline anchoring pier, wherein described Flat steel pipe fixes the periphery for being scheduled on ground hot oil pipeline, and ground hot oil pipeline is fixed on channel-section steel by band steel pipe clamp, foundation bolt is arranged at the channel-section steel bottom, and be fixed on channel-section steel by foundation bolt in the cement buttress of lower section, it is provided with wooden backing plate below described ground hot oil pipeline；Advantage is：The anchoring pier of the utility model structure type has the advantages that pier body is small, is easy to anti-corrosion, favorable anti-corrosion effect, avoid stress concentration, be easy to construction and later stage checking maintenance.
Description
Technical field
The utility model is related to deep fat buried pipeline field, and pipeline at pier is anchored more particularly, to a kind of deep fat buried pipeline
Anti-corrosive apparatus.
Background technology
In hot oil pipeline operation heating coil, with the rise of pumped (conveying) medium temperature, it may occur that heat expansion phenomenon, elbow both sides are straight
The heat expansion stress of pipe will be concentrated to elbow, and elbow is easy under stress produce extruding and flexural deformation, when thermal stress is led
Cause elbow occur lateral displacement overstep the extreme limit displacement when, strength failure will occur for elbow, cause elbow occur crackle, deformation
Until causing leakage.To prevent pipeline from causing pipeline to occur strength failure or arch camber because axial stress is excessive, in pipe design,
The soil section that can be come in and gone out in pipeline and elbow set anchoring pier.Current buried heated pipeline anchoring pier is typically fixed using band sleeve pipe cement
Pier（See Fig. 1）, there is big pier body, reinforcement weld stress concentration or weld defect, sleeve pipe intraformational bed in the anchoring pier of the pattern
Belong to irregular shape at anti-corrosion leak, in addition reinforcement, scene derusting and anticorrosive construction are difficult, antiseptic effect is poor etc. asks
Topic, causes anchor block interior conduit to there is certain corrosion risk, very big potential safety hazard is brought to oil pipeline safe operation.
The content of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, and provides a kind of deep fat
Pipeline corrosion protection device at buried pipeline anchoring pier.
The new technical scheme of the utility model is：Pipeline corrosion protection device at a kind of deep fat buried pipeline anchoring pier, including ground
Hot oil pipeline, band steel pipe clamp, channel-section steel, cement buttress, foundation bolt and wooden backing plate, described Flat steel pipe, which is fixed, is scheduled on ground deep fat
The periphery of pipeline, and ground hot oil pipeline is fixed on channel-section steel by band steel pipe clamp, foundation bolt is arranged at the channel-section steel bottom, and passes through ground
Channel-section steel is fixed in the cement buttress of lower section by foot bolt, and wooden backing plate is provided with below described ground hot oil pipeline.
Using insulation rubber between described band steel pipe clamp and ground hot oil pipeline.
Ground hot oil pipeline is fixed by welding on channel-section steel by described band steel pipe clamp.
Described wooden backing plate is spill.
The beneficial effects of the utility model are：The anchoring pier of the utility model structure type has that pier body is small, is easy to anti-corrosion,
Favorable anti-corrosion effect, avoid stress concentration, be easy to construction and the advantages of later stage checking maintenance.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein：1 be ground hot oil pipeline, 2 be band steel pipe clamp, 3 be channel-section steel, 4 be cement buttress, 5 be foundation bolt, 6 be wood
Matter backing plate.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings.
Pipeline corrosion protection device at a kind of deep fat buried pipeline anchoring pier, including ground hot oil pipeline 1, band steel pipe clamp 2, channel-section steel 3,
Cement buttress 4, foundation bolt 5 and wooden backing plate 6, described band steel pipe clamp 2 are fixed on the periphery of ground hot oil pipeline 1, and band steel
Ground hot oil pipeline 1 is fixed on channel-section steel 3 by pipe clamp 2, and foundation bolt 5 arranged at the bottom of channel-section steel 3, and by foundation bolt 5 by groove
Steel 3 is fixed in the cement buttress 4 of lower section, and the described lower section of ground hot oil pipeline 1 is provided with wooden backing plate 6.
Using insulation rubber between described band steel pipe clamp 2 and ground hot oil pipeline 1.
Ground hot oil pipeline logical 1 is crossed and is weldingly fixed on channel-section steel 3 by described band steel pipe clamp 2.
Described wooden backing plate 6 is spill.
(1) buried heated pipeline is anchored on the channel-section steel 3 of butt welding using band steel pipe clamp 2, by foundation bolt 5 by groove
Steel 3 is fixed on the cement buttress 4 of lower section, and the heat expansion stress that pipeline is produced passes through the cement below pipe clamp indirectly-acting to pipeline
On buttress 4, and then avoid pipeline generation stress concentration, cause stress corrosion.
(2) band steel pipe clamp 2 is with pipeline enclosure using insulation rubber, and on the one hand frictional force between increase pipeline and pipe clamp, another
Aspect is avoided above pipeline and the destruction of side external anti-corrosion layer, plays indirect antisepsis.
(3) the wooden backing plate 6 of spill is set below pipeline, on the one hand plays firm pipeline（Wooden backing plate 6 meets water and swells, increases
Big pipeline and pipe clamp frictional force）, on the other hand avoid lower end of duct external anti-corrosion layer from destroying, play indirect antisepsis.
Clip form proposed by the present invention anchors buried heated pipeline with using pipeline will be buried with sleeve pipe Type of Welding
Hot oil pipeline anchor structure form is compared：With pier body it is small, be easy to anti-corrosion, favorable anti-corrosion effect, avoid stress concentration, be easy to construction
The advantages of with later stage checking maintenance.
