Abstract
The present invention relates to a method for hoisting a large scale concrete box girder, which belongs to the technical field of bridge construction. The method for hoisting a large scale concrete box girder is characterized in that a soft hoisting belt is adopted for binding, a vertical hoisting mode is used for hoisting, and therefore, the damage of the box girder with length of more than 60 m and self weight of more than 1600 ton, which is brought by horizontal divided force because of the non-vertical hoisting mode, is avoided; the soft hoisting belt easily selects a reasonable binding force application point, and is conveniently binded; the stiff characteristics of the binding process of a steel rope do not exist, and the binding process of the steel rope is not convenient and is easy to cause the damage. A large scale sea floating hoister with mature technology is used for hoisting a hoisting rack, and the design and the manufacture of a special purpose floating crane are omitted. The cost is saved, the period is greatly shortened, and the method for hoisting a large scale concrete box girder is a method with high engineering construction value under the construction of large scale bridges, such as large sea spanning bridges.
Description
Technical field
The invention belongs to technical field of bridge construction, exactly is a kind of method of lifting large concrete boxes beam.
Background technology
The effect of building traffic of bridge spanning the sea has the important strategic meaning, and China begins and will build many bridge spanning the seas successively from Donghai Bridge.In order to improve efficiency of construction and working security, reduce the offshore construction amount in the bridge spanning the sea building course as far as possible, therefore adopted mostly at prefabricated place precast unit, be transported to the offshore construction platform again and carry out the job practices that set up at the sea.And large scale prefabricated concrete box girder is as the important component in the bridge spanning the sea, and it is big to have a volume, self heavily waits characteristics, is the main difficult point in the work progress.
In order to set up being transported to offshore construction platform place at the prefabricated concrete box girder of precasting yard, must lift by crane the harbour of case beam, therefore just exist and play the box beam and adopt which kind of lifting to bring colligation and fixed case beam with which kind of structural establishment from precasting yard.
Mostly adopted special-purpose crane ship during existing bridge spanning the sea is built, the characteristics of this ship are that special setting up for the transportation of particular box beam built, and its hull has a fixing frame construction.The steel truss structure of upending frame for cooperating hull and case beam to make: the fixed case beam adopts the similar shoulder pole structural mat of a slice girder steel in case beam bottom, at four angle points of girder steel steel suspension rod suspension centre is set again, is fixed in by the steel suspension rod and plays the box beam on the upending frame.
Having used special-purpose crane ship, its suspension bracket and suspender belt mostly by the existing as can be known prefabricated large concrete boxes beam lifting of above introduction all is member with the supporting design of crane ship.Owing to crane ship is to make for box beam erection specially, its construction application scope is narrower and manufacturing cost is very high, and the cycle is also long.Therefore unit in charge of construction or follow traditional method and remove to make a special-purpose crane ship and its supporting member; The abandoning tradition way is sought new way.
It is long that my company has born more than 60 meter of Donghai Bridge, self weigh into more than 1600 ton non-navigation hole case beam prefabricated, set up task.Whether does my company also remove to make so special-purpose crane ship and its special-purpose assorted member?
Summary of the invention
The present invention provides and a kind ofly can lift by crane more than 60 meter long, more than 1600 ton the large concrete boxes beam that weighs certainly, and do not go specialized designs, make the suspension bracket of special-purpose crane ship and its supporting design and a kind of large concrete boxes beam hoisting method of suspender belt.
The technical scheme that the present invention takes:
According to vertical lifting requirement, determine prefabricated case beam lifting origin of force; According to origin of force, determine case back plate lead to the hole site, and construct through hole, the soft suspender belt that the high-strength polyester long filament that adopts safety factor to reach 5: 1 makes, soft suspender belt color is orange international standard look, passes through hole, vertically bundlees the case beam, soft suspender belt vertical direction is fixed on lifting sets a roof beam in place, and implements lifting upending frame by large-scale marine crane barge.
After implementing the present invention:
Owing to be to adopt soft suspender belt, pass case beam through hole easily, avoided the difficulty of cable wire hardness perforation and the damage that brings, adopt vertical lifting to avoid the lifting horizontal component that brings because of non-perpendicular lifting destructive power to case beam surface, and, improve antiwear property, and utilize technology maturation at suspension centre increase PES sheath, use the lifting of more large-scale marine crane barge enforcement to upending frame, save manufacturing and designing of special-purpose crane ship, provided cost savings, greatly shortened the cycle.
Description of drawings
Fig. 1, soft suspender belt are fixed in case beam vertical section schematic diagram;
Fig. 2, upending frame play box beam schematic diagram;
Fig. 3, upending frame plan structure schematic diagram;
The specific embodiment
Now the invention will be further described in conjunction with the accompanying drawings, at first to prefabricated case beam 1, require to determine the lifting origin of force according to vertical lifting, according to origin of force, determine the position of case back plate through hole 4, and construct through hole 4, the soft suspender belt 2 that the high-strength polyester long filament that adopts safety factor to reach 5: 1 makes, soft suspender belt color is a salmon pink international standard look, pass through hole 4, vertically be bundled in case beam 1, and with bottle gouard moved by hands 3, tighten up soft suspender belt 2, the head that hangs of soft suspender belt 2 is hung on the hook of hydraulic jack 5, by the upending frame that hanger box beam 8 and suspension bracket truss 9 constitute, the case beam 1 of vertically slinging, large-scale marine crane barge is implemented lifting to case beam 1 easily by suspension hook 6.
