Description
Technical field
The present invention relates to the construction method of installation of the traction system that a kind of bridge cat road sets up, main push-towing rope is installed.
Background technology
Trailer system sets up core and is that first dragline crosses the river; Normally cross the river earlier with thinner wire rope earlier; Utilize its first dragline to guide river (wire rope from carefully to thick) in the air again; Main method has: lay under water that method, free suspension method, crane barge are set up method, helicopter sets up method and balloon suspension method etc., transfers the haulage cable of anchor road track cable or main cable strand at last to.Trailer system normally relies on the transition elder generation dragline that sets up in advance to carry out installation.
Sun patrol bridge adopt first dragline under water the method for laying drew the river; Its main feature is after accomplishing first dragline connection; The drag cable of its trailer system sets up at Mao Dao need set up drag cable again; Many, iceound times of aerial work are long, operation is loaded down with trivial details, difficulty of construction is high, and safety is difficult to be guaranteed.
Summary of the invention
In order to overcome above-mentioned deficiency, the object of the present invention is to provide a kind of bridge cat road to set up and first dragline that main push-towing rope can effectively be installed trailer system when installing is crossed river and the incorporate job practices of traction system.That this method has is quick for installation, construction safety, the iceound time weak point in navigation channel, duration weak point, quality assurance, characteristics such as easy to operate.
To achieve these goals, the technical scheme of the present invention's employing is:
Elder generation's dragline is crossed river and the incorporate job practices of traction system, may further comprise the steps: A, preparation of construction: in the two sides of construction, every bank is all established tower body, first dragline hoist engine, anchorage and main winch; B, erecting guide rope; C, set up drag cable: an end of the drag cable on the main winch of two sides is caused cat head respectively, utilize first dragline that one end of the drag cable of the top of tower of one bank is drawn to the top of tower on opposite bank, the termination of two drag cables is connected; Start the main winch of two sides, the main winch rolling of a bank, the main winch of the other end is put rope, to setting up completion to drag cable.
The step of said step B comprises: 1. stride on the first dragline hoist engine on the side assistance platform on tower base, two sides; Be involved in first dragline respectively; Guide's rustling sound head is promoted to cat head,, transfers a side near a river to tower through the cat head roller steering; At the bottom of respectively guide's rustling sound head being temporarily fixed at tower, prepare to be connected with tugboat; 2. to can the part navigation channel carry out iceound, the iceound district in the part, tugboat, barge, that control vessel arrives assigned address is in place, the location barge is in the predetermined point location of casting anchor; 3. utilize tugboat to draw bank elder generation dragline to station keeping ship, be connected on the station keeping ship temporarily, first dragline hoist engine imposes suitable counter-force to first dragline in this process, keeps rope not get in the water; 4. all iceound, utilize tugboat that two sides elder generations dragline is led to station keeping ship and connect temporarily, connect two sides elder generation dragline, remove respectively and being connected of station keeping ship; 5. start two sides elder generation dragline hoist engine, promote first dragline and cross the river, one receives one puts, and through cat head, the adjustment sag is beaten tip anchoring temporarily one bank elder generation dragline to the absolute altitude of opening the navigation or air flight at two cats head, removes bank elder generation dragline until two sides elder generation dragline connector; 6. remove iceoundly, accomplish setting up of first dragline.
The step of said step C comprises: the 1# drag cable is set up at a bank in (1): 1. the 1# drag cable is involved in traction main winch rope roll, lays the interim support roller of drag cable; 2. start main rack winch and put rope, utilize first dragline hoist engine, the 1# drag cable is linked to each other with first dragline hoist engine wire rope, draw to the tower root through directive wheel, first dragline hoist engine tractive promotes 1# traction rustling sound head to cat head, is connected with opposite bank guide's rustling sound head; 3. start earlier the traction main winch make end bay dragline tension force with in stride basic identical; Remove dragline at two cat head place temporary consolidations, start opposite bank elder generation dragline hoist engine, be involved in opposite bank elder generation dragline; The traction of 1# drag cable is walked around cat head, played the temporary fixed 1# traction of tip drag cable at cat head.In the distraction procedure, main rack winch applies suitable counter-force, prevents the drag cable bounce-back, and the drag cable of 1# adjustment at any time sag, guarantees headway; 4. meanwhile, carry out the 2# drag cable on the opposite bank and set up, on the main rack winch of this bank; Arrange 2# traction rustling sound dish; The 2# drag cable is involved in the main rack winch rope roll, 2# is drawn the rustling sound head cause this bank top of tower, pull device in the top of tower utilization of this bank the 1# rope is linked to each other with the 2# rope; 5. start both sides master's rack winch, remove the cat head temporary consolidation, the adjustment drag cable forms the reciprocating type trailer system of single line to design height.
The diameter of said 1# drag cable and 2# drag cable is 36mm; The diameter of said first dragline is 24mm.
Said first dragline hoist engine adopts the hoist engine of 20T, and said main winch adopts the hoist engine of 25T.
Beneficial effect of the present invention: its working procedure is reasonable, ancillary method is few, and construction efficiency is high, the time is short, safety is controlled, practice thrift cost, and integrated have with characteristics under the structure:
(1) the integrated plant equipment of utilizing trailer system does not increase other big ancillary method, promptly adopts rack winch, main push-towing rope to pull hoist engine, pulls device;
(2) integrated installation trailer system one-shot forming, make working procedure rationally, guarantee safety.Promptly under the situation of short iceound time, accomplish, the installation of the transition traction of minimizing reaches carries out the installation of pull rope under innavigable situation;
(3) upstream and downstream is independently laid, and reduces aerial erection construction step, has reduced a large amount of construction ancillary methods;
(4) short construction period, work efficiency are high, security performance is high.
