Abstract
The invention relates to a joint coating plate fusion welding high-pressure clamp for a prefabricated directly-buried insulating pipeline system. According to joint coating construction of a prefabricated directly-buried insulating pipeline joint, the underground quality of a coated joint welded in a fusion mode can not be guaranteed for long, and along with crustal changes, a fusion welding part may fracture or break away from a fusion welding position in the future. The joint coating plate fusion welding high-pressure clamp comprises a fastening plate (1) in a C-shaped belt shape, a set of fastening vertical plates (5) extends out of an opening of the fastening plate (1) in the C-shaped belt shape, a fastening bolt hole (6) is formed in each fastening vertical plate, a supporting and fastening plate (3) is arranged between each fastening vertical plate and the fastening plate, and a set of clamping teeth (4) is arranged on the inner wall of the fastening plate and connected with a ring-shaped inflating belt (2). The joint coating plate fusion welding high-pressure clamp is used for the prefabricated directly-buried insulating pipeline system.
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:
current prefabricated direct-buried thermal insulation pipe pipeline joint field joint construction, the state-of-the-art method used accomplishes repaired mouth plate and the outer seamless welding of pillar of pipeline, ensure that soil moisture has no way of infiltrating heat-insulation layer, thus improve insulation, energy-conservation, reduce discharging resultant effect, but the repaired mouth of welding is permanent without collateral security at the intact time limit of the quality of underground, along with the variation of the earth's crust fracture of welding position or de-molten problem also can occur at future, cause maintenance, maintenance costs will occur increasing future makes the effects of energy saving and emission reduction of pipeline can not reach the design object effect of pipeline.
summary of the invention:
the object of this invention is 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 object 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 comprises: binding, described binding becomes C shape banded, the banded opening of described binding C shape stretches out one group of fastening riser, described fastening riser has fastening bolt holes, have one group between described fastening riser and binding and support binding, described binding 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 by high pressure fibrous material and rubber, described round aeration zone in a tubular form, described binding is manufactured by stainless steel synthetic metals, described binding width 5-15cm, thick 1-3mm, described clamping dental length 1-5cm.
the clamping method of described prefabricated direct-buried thermal insulation pipe road system repaired mouth plate fusion welding high-voltage fixture, it is when carrying out prefabricated direct-buried thermal insulation pipe road system repaired mouth plate fusion welding high pressure clamping, first a part is round aeration zone, it is synthesized by high pressure fibrous material and rubber, aeration zone in a tubular form, inside can gassy, and can bear the pressure of 5 kilograms, another part is metal fastening clips, it is manufactured by stainless steel synthetic metals, when field joint construction, after repaired mouth plate is in the outer pillar being wrapped in insulating tube closely, the aeration zone of round is centered around repaired mouth plate both sides, cast aeration zone is made to be circle shape, then to insufflation gas in aeration zone, it is made to reach enraged shape, be fixed on the posetionof weld of repaired mouth plate after, C row metal fixture is wrapped in round aeration zone outside, dentation is bent in draw-in groove and firmly blocks round aeration zone, after the bolt clamping in the fastening bolt holes on fastening riser, inflate to aeration zone, and make pressure in aeration zone reach 0.1-0.5mpa, after stable gas pressure, then repaired mouth plate welding work is carried out.
beneficial effect of the present invention:
1. the present invention fastening with current cassette tape compared with, be by the equilibrium of air pressure, stablize feature, enhance the degree of depth compactness of repaired mouth plate and the welding of outer pillar repaired mouth.
round aeration zone of the present invention, metal fastening reinforcement fixture quality are first-class, and fast, feature is rapidly shifted in carrying, belongs to the replacement instrument of repaired mouth welding construction in operation.
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 more deeply, more abundant, repaired mouth plate and outer pillar is made to become integral pipe more closely, thus during the earth's crust in 30 years slowly changes, there will not be the uneven fracture that causes of de-molten, fusing point and gap, ensure that heat-insulation layer infiltrates without moisture, to be consistent identical, stable insulation, energy-conservation, the effect that reduces discharging with insulating tube, to have saved huge maintenance cost.
