Description

Guide cable crosses the river construction method integrated with Traction sysytem
Technical field
The present invention relates to the construction method of installation of the Traction sysytem that a kind of bridge cat road sets up, main push-towing rope is installed.
Background technology
Trailer system erection core is that guide cable crosses river, normally first first cross river with thinner wire rope, recycle its guide cable and be led through river (wire rope is from thin to thick) in the air, main method has: underwater laying method, free suspension method, crane barge erection method, helicopter erection method and balloon suspension method etc., finally transfer the haulage cable of anchor road track cable or main cable strand to.Trailer system normally relies on the transition guide cable set up in advance to carry out installation.
Sun is patrolled bridge and is adopted guide cable underwater laying method to draw river, its main feature has been after guide cable connects, in cat road, erection need re-start erection drag cable to the drag cable of its trailer system, aerial work many, iceound time is 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 guide cable effectively installing trailer system when the object of the present invention is to provide the erection of a kind of bridge cat road and main push-towing rope to install crosses the river construction method integrated with Traction sysytem.The method has quick for installation, construction safety, the navigation channel iceound time is short, the duration is short, quality assurance, the feature such as easy to operate.
To achieve these goals, the technical solution used in the present invention is:
Guide cable crosses the river construction method integrated with Traction sysytem, comprises the following steps: A, preparation of construction: in the two sides of construction, and every bank all establishes tower body, guide cable hoist engine, anchorage and main winch; B, erecting guide rope; C, erection drag cable: one end of the drag cable on the main winch of two sides is caused tower top respectively, utilizes guide cable 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 puts rope, to having set up to drag cable.
The step of described step B comprises: 1. on tower base, two sides across on the guide cable hoist engine on the assistance platform of side, be involved in guide cable respectively, guide's rustling sound head is promoted to tower top, through tower top roller steering, transfer the side near a river to tower, respectively guide's rustling sound head is temporarily fixed at the bottom of tower, prepares to be connected with tugboat; 2. to carrying out iceound in part navigation channel, in iceound district, local, it is in place that tugboat, barge, control vessel arrive assigned address, and location barge to cast anchor location at predetermined point; 3. utilize tugboat to draw a bank guide cable to station keeping ship, be connected on station keeping ship, in this process, guide cable hoist engine imposes suitable counter-force to guide cable temporarily, keeps rope not enter in water; 4. all iceound, utilize tugboat to be led by two sides guide cable and connect to station keeping ship temporarily, connect two sides guide cable, remove the connection with station keeping ship respectively; 5. start two sides guide cable hoist engine, promote guide cable and cross river, one receives one puts, until two sides guide cable connector is by tower top, adjustment sag, to absolute altitude of opening the navigation or air flight, is beaten tip anchoring temporarily one bank guide cable at two tower tops, removed a bank guide cable; 6. remove iceound, complete the erection of guide cable.
The step of described step C comprises: (1) is at a bank erection 1# drag cable: 1. 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 guide cable hoist engine, be connected by 1# drag cable with guide cable steel wire rope of windlass, through directive wheel traction to tower root, guide cable hoist engine tractive promotes 1# and draws rustling sound head to tower top, is connected with opposite bank guide's rustling sound head; 3. first start traction main winch make end bay dragline tension force with in across substantially identical, remove dragline at two tower top place temporary consolidations, start opposite bank guide cable hoist engine, be involved in opposite bank guide cable, 1# drag cable is led around tower top, beats the temporary fixed 1# of the tip at tower top and draw drag cable.In distraction procedure, main rack winch applies suitable counter-force, prevents drag cable from rebounding, and 1# adjusts drag cable sag at any time, ensures headway; 4. meanwhile, the erection of 2# drag cable is carried out on the opposite bank, on the main rack winch of this bank, arrange that 2# draws rustling sound dish, 2# drag cable is involved in main rack winch rope roll, 2# is drawn rustling sound head and cause this bank top of tower, pull device in the top of tower utilization of this bank and 1# rope is connected with 2# rope; 5. start the main rack winch in both sides, remove tower top temporary consolidation, adjustment drag cable, to design height, forms single line reciprocating-type tractor system.
The diameter of described 1# drag cable and 2# drag cable is 36mm; The diameter of described guide cable is 24mm.
Described guide cable hoist engine adopts the hoist engine of 20T, and described main winch adopts the hoist engine of 25T.
Beneficial effect of the present invention: its working procedure is reasonable, ancillary method is few, construction efficiency is high, the time is short, safety is controlled, cost-saving, and integration has with feature under structure:
(1) integration utilizes the plant equipment of trailer system, does not increase the ancillary method that other is large, namely adopts rack winch, main push-towing rope pulls hoist engine, pull device;
(2) integrative installation technology trailer system one-shot forming, make working procedure rationally, guarantee safety.Namely complete when the shorter iceound time, the installation of the transition of minimizing traction and carry out the installation of pull rope in innavigable situation;
(3) upstream and downstream is independently laid, and reduces aerial erection construction step, decreases a large amount of construction ancillary methods;
(4) short construction period, work efficiency is high, security performance is high.
