The method of forming bridge crossing

 

The invention relates to the field of construction of bridges, and more particularly to a tip floating bridges. The method of forming bridge crossing includes discharging the water pontoon parts, the connection between the tape along the original shore and turn the tape over the relatively low end of the specified target using tug boats, attached to the ribbon. What's new is that the tape simultaneously with the turning away from the original shore with a tug attached to it by the Board, move on over, fix the lower end of the tape to the original Bank in the specified target and dovorachivat tape boat before placing it in the specified target. Technical result provided by the invention, consists in the possibility of reducing the time of formation of the bridge crossing by providing a rotation of the entire tape, collected from a pontoon links along the original shore, in the specified target even if the Bank of the obstacles that turn. 1 Il.

The invention relates to the field of construction of bridges, and more particularly to a tip floating bridges.

There is a method of education bridge crossing, including unloading on the water pontoon the business end of a specified target using tug boats, attached to the ribbon (see Guide pontoon-bridge Park RAP. Moscow, Voenizdat, 1965, S. 156-166).

The disadvantage of this method of education bridge crossing is that it is not applicable in cases when the initial winding shore, or which has a dam, shoals, etc. that interfere with the rotation of the tape.

Known closest to the invention a method of forming bridge crossing, including unloading on the water pontoon parts, the connection between the tape along the original shore and turn the tape over the relatively low end of the specified target using tug boats, attached to the ribbon (see Pontoon Park special GSS-84. Book 3. Equipment and maintenance of river crossings. Moscow, Voenizdat, 1990, S. 33-39).

The disadvantage of this method of education bridge crossing is that it is not applicable in cases where the shore there are obstacles (which dams, shallow, submerged objects), not allowing to turn the collected tape in the specified target. In these cases, the bridge crossing is formed by Assembly of pontoon units of individual sections of the tape, enter them using tug boats in the specified target and a connection between what Sadovoy terminal by providing the possibility of turning the whole tape, collected from pontoon links along the original shore, in the specified target even if the shore obstacles this turn.

The solution of the stated problem is achieved in that in the method of forming bridge crossing, including unloading on the water pontoon parts, the connection between the tape along the original shore and turn the tape over the relatively low end of the specified target using tug boats attached to the tape, according to the invention the tape simultaneously with the turning away from the original shore with a tug attached to it by the Board, move on over, fix the lower end of the tape to the original Bank in the specified target and dovorachivat tape boat before placing it in the specified target.

The technical result provided by the present set of features, is to provide the possibility of reducing the time of formation of the bridge crossing by providing rotation of the tape in the specified target even if the shore obstacles.

The method of formation of the bridge crossing is illustrated in the drawing.

Education bridge crossing is carried out in the following order.

Pontoon units 1 discharged to water and buxomy boat 2 and Board the tug boat 3. The lower end of the tape secured with the rope to the original Bank (position I). Then, releasing the lower end of the tape from consolidation, the simultaneous movement of a boat 2 back and 3 boats forward motion away the tape from the original shore (position II). Further movement of the cutters 2 and 3 reverse moves the tape with the flow and let its downstream end to the original Bank in the specified target (position III). After that fix the lower end of the tape to the original Bank and dovorachivat tape cutter 2 before placing it in the specified target (position IV). Then the boat 3 turn on the 90oand fixed to the tape nose against the current.

Upon completion of the operation of the bridge crossing the tape in whole or in separate parcels served to the opposite shore, assort on the pontoon parts and load them into the car.
