Description
Technical field:
The present invention relates to a kind of prefabricated direct-buried thermal insulation pipe road system repaired mouth plate fusion welding high-voltage fixture and clamping method.
Background technology:
Prefabricated direct-buried thermal insulation pipe pipeline joint field joint construction at present, the state-of-the-art method used is to accomplish the outer seamless welding of pillar of repaired mouth plate and pipeline, ensure that soil moisture has no way of penetrating into heat-insulation layer, thus improve insulation, energy-conservation, the resultant effect of reduction of discharging, but the intact time limit of quality that the repaired mouth of welding is in underground is permanent without collateral security, along with the variation of the earth's crust is following it also occur that the fracture of welding position or de-molten problem, maintenance, maintenance costs is caused to occur increasing the design object effect making the effects of energy saving and emission reduction of pipeline can not reach pipeline future.
Summary of the invention:
It is an object of the invention to provide a kind of prefabricated direct-buried thermal insulation pipe road system repaired mouth plate fusion welding high-voltage fixture and clamping method.
Above-mentioned purpose is realized by following technical scheme:
A kind of prefabricated direct-buried thermal insulation pipe road system repaired mouth plate fusion welding high-voltage fixture, its composition includes: fastening plate, described fastening plate becomes C-shaped banding, the C-shaped banding opening of described fastening plate stretches out one group of fastening riser, on described fastening riser, there is fastening bolt holes, having one group of fastening support plate between described fastening riser and fastening plate, described fastening plate inwall has one group of clamping tooth, described clamping tooth is connected with round aeration zone.
Described prefabricated direct-buried thermal insulation pipe road system repaired mouth plate fusion welding high-voltage fixture, described round aeration zone is synthesized with rubber by high pressure fibrous material, described round aeration zone is in a tubular form, described fastening plate is synthesized metal manufacture by rustless steel, described fastening plate width is 5-15cm, thickness is 1-3mm, and described clamping dental length is 1-5cm.
The clamping method of described prefabricated direct-buried thermal insulation pipe road system repaired mouth plate fusion welding high-voltage fixture, when carrying out prefabricated direct-buried thermal insulation pipe road system repaired mouth plate fusion welding high pressure clamping, round aeration zone, inside can gassy, and the pressure of 5 kilograms can be born；When field joint construction, after repaired mouth plate is in being wrapped in the outer pillar of insulating tube closely, the aeration zone of round is centered around repaired mouth plate both sides, making round aeration zone is circle shape, then insufflation gas in aeration zone, reach tympanites shape, after being fixed on the posetionof weld of repaired mouth plate, the fastening plate of C-shaped banding is wrapped in outside round aeration zone, make clamping tooth consolidate and block round aeration zone, after the bolt clamping in the fastening bolt holes on fastening riser, inflate to aeration zone, and pressure reaches 0.1-0.5mpa in making aeration zone, after stable gas pressure, carry out repaired mouth plate welding work.
Beneficial effects of the present invention:
1. the present invention is compared with the fastening of current cassette tape, is by the equilibrium of air pressure, stablizes feature, enhances the degree of depth compactness of repaired mouth plate and outer pillar repaired mouth welding.
It is first-class that fixture quality is strengthened in the fastening of round aeration zone of the present invention, metal, and quickly, rapid feature is shifted in carrying, belongs to the replacement instrument of repaired mouth welding construction in operation.
The repaired mouth of the present invention is installed, the outer pillar of repaired mouth plate and insulating tube is made firmly to be combined completely, welding deeper, more abundant, repaired mouth plate and outer pillar is made to become more close integral pipe, thus during the earth's crust in 30 years slowly changes, do not have de-molten, the uneven fracture caused of fusing point and gap, it is ensured that heat-insulation layer penetrates into without moisture, keep consistent identical, stable insulation, energy-conservation, the effect of reduction of discharging with insulating tube, save huge maintenance cost.
