Abstract
This invention discloses a protection method of alachlor anchorage, which comprises the following steps: A, bundling the alachlor anchorage inside the channel absolutely with a inner liner tube and separating the alachlor channel; B, pressing the protection material inside the inner liner tube to cover the anchorage absolutely; C, normally protecting the outer part of the tie-plate. Wherein the inner liner tube is integrated by the flanging board and the tube barrel, and the flanging board is arranged between the anchor slab and the cap nut, the tube barrel is covered between the alachlor anchorage and the alachlor channel. Applying this method can ensure the anchorage does not corrosion. In can be also set a drain hole in the alachlor channel lower or in the anchor slab to avoid the impoundment in the channel, and can decide the channel whether inflow water by observing the drain hole leak or not, so to repair the water-proof facilities in time.
Description
Technical field:
The present invention relates to building field, particularly a kind of means of defence of dragline anchorage.
Background technology:
Fast development along with the modern construction engineering science and technology, adopt (steel wire, wire rope, steel strand) drag-line to can be found everywhere as the Cable Structure engineering construction of supporting member, as cable stayed bridge, suspension bridge, be (hanging) bar arch bridge, adopt colosseum, departure lounge, aerodrome even TV transmission tower of Cable Structure ceiling or the like.Steel wire is coupled as one solid and reliablely in the ground tackle at drag-line two ends and the rope, and gives drag-line with dead load and other loading transfer, and the importance of dragline anchorage is conspicuous.In order to make ground tackle long-term operate as normal under various environments for use, must effectively protect it.
Suspension cable in the cable stayed bridge directly bears loads such as bridge deck structure deadweight and vehicle, crowd, and its two ends ground tackle is individually fixed in tower end (bridge tower structure) and beam-ends (bridge deck structure); The suspension rod of suspension bridge, and be that the dragline anchorages such as suspension rod of (hanging) bar arch bridge are fixed in main push-towing rope, arch rib and girder respectively.The protection of dragline anchorage comprises upper end (tower, main push-towing rope, arch rib) and lower end (girder) two parts.Wherein upper end invar pipe is suitable for reading is the anchor-hold point, presses closely connectedly between anchoring nut and anchor plate, can not intake in the drag-line pipeline, as long as carry out the protection of ground tackle.Having problems more is the water inlet of lower end drag-line pipeline and the protection of ground tackle.It is reported, there is the lower end (beam-ends) of drag-line with the suspension rod of quite a few cable stayed bridge, arch bridge and suspension bridge to have the different water inlet phenomenon of degree, steel wire to ground tackle even drag-line causes serious corrosion, the drag-line of some bridges is had to be changed in advance, and the corrosion of indivedual bridge Yin Lasuo is ruptured and caused a serious accident.By analysis, the beam-ends pipe water has two aspects usually: the one, enter from the steel sleeve opening part; The 2nd, infiltrate along the protective sleeve of pulling cable outer wall.Therefore, need to seek a kind of means of defence at drag-line lower end ground tackle.
Summary of the invention:
The purpose of this invention is to provide a kind of dragline anchorage guard technology at drag-line lower end ground tackle, this technology can effectively protect dragline anchorage to avoid corrosion, prolongs its normal service life.
To achieve these goals, technical scheme of the present invention is: a kind of method for protecting guy anchor may further comprise the steps: A, the dragline anchorage that will be positioned at pipeline with an internal lining pipe wrap up fully, with the drag-line pipeline isolation; B, in internal lining pipe the pressure injection protective materials, ground tackle is all covered; C, part beyond the anchor plate is carried out routine protect.
Wherein internal lining pipe is made up of internal lining pipe flanged plate and the internal lining pipe cylindrical shell that is attached thereto.
Adopt this method, also can not produce corrosion ground tackle even can guarantee pipe water.
In addition a spilled water hole can be set in the bottom of drag-line pipeline,, also can whether drip to judge in the drag-line pipeline whether intake, and can be in time the anti-drainage facility of upper end be keeped in repair by observing spilled water hole to avoid ponding in the pipeline.
Description of drawings:
Fig. 1 is the schematic diagram of one embodiment of the invention
The specific embodiment:
Below in conjunction with drawings and Examples the present invention is further described.
A kind of method for protecting guy anchor may further comprise the steps: A, the dragline anchorage 8 that will be positioned at pipeline with an internal lining pipe 1 wrap up fully, isolate with drag-line pipeline 9; B, in internal lining pipe 1 pressure injection protective materials 4, dragline anchorage 8 is all covered; C, part beyond the anchor plate 7 is carried out routine protect.Wherein internal lining pipe 1 is made up of internal lining pipe flanged plate 2 and the internal lining pipe cylindrical shell 3 that is attached thereto.
Wherein steps A may further comprise the steps again: a, dragline anchorage 8 is penetrated drag-line pipeline 9, expose to anchor cup 6; B, internal lining pipe 1 is inserted between drag-line pipeline 9 and the dragline anchorage 8, screws in nut 10, drag-line is in place, makes internal lining pipe flanged plate 2 between anchor plate 7 and nut 10, and drag-line is stretched to designs Suo Li.The design Suo Li of suspension cable generally is not more than 0.4 times the disrumpent feelings Suo Li of nominal.
Wherein step B may further comprise the steps again: c, an elongated tubular is fixed in one is enclosed within on the outer ringlet of drag-line, stretch into internal lining pipe 1 to the bottom along drag-line; D, utilize elongated tubular that protective materials is injected in the internal lining pipe cylindrical shell 3,, and dragline anchorage 8 covered fully until internal lining pipe 1 nozzle.
Wherein internal lining pipe 1 can adopt stainless steel or other resistant material to make.Conventional protection is smeared protective materials for the anchor cup 6 of part and the surface of nut 10 beyond anchor plate 7.Protective materials can be a slushing oil.The guard shield 5 of also can setting up defences on anchor plate 7 makes anchor plate 7, internal lining pipe flanged plate 2, nut 10 and anchor cup 6 be positioned within the protective cover 5.
In addition a spilled water hole 11 can be set in the bottom of drag-line pipeline 9,, also can whether drip to judge in the drag-line pipeline whether intake, and can be in time the anti-drainage facility of upper end be keeped in repair by observing spilled water hole 11 to avoid ponding in the pipeline.
