Description

A kind of dragging suspension basket that is applicable to the wide cut double plane cable stayed bridge
Technical field
The utility model discloses a kind of bridge construction equipment, particularly a kind of dragging suspension basket that is applicable to the wide cut double plane cable stayed bridge.
Background technology
Along with the development of bridge engineering designing technique, the application of large span rigid frame bridge beam, cable-stayed type bridge is increasingly extensive, and the thing followed is that the use of Hanging Basket is also increased, and the cradle structure form is more and more, Hanging Basket to practical, direction is in continuous development easily.Mainly by two kinds on self-bearing type structure and hauling-rope type structure, the former can be divided into structures such as triangle, rhombus again to the Hanging Basket of engineering field practicality at present; The latter can be divided into long platform form and short platform form.
No matter the common cantilever Hanging Basket of self-bearing type is that triangle or rhombus are the rear fulcrum form, utilizes and has watered sections as anchor point, by anti-construction of hanging realization back one sections.This Hanging Basket is that single-cantilever is stressed, and is bigger owing to adopting cantilever construction thereby bearing hogging moment, so build sections length limited system.And dragging suspension basket can make full use of the effect of suspension cable to become the cantilever hogging moment stressed stressed into freely-supported positive bending moment, builds length and supporting capacity like this and can improve greatly.
Dragging suspension basket is divided into long platform dragging suspension basket and the compound dragging suspension basket of short platform according to Hanging Basket land lengths difference.The short platform dragging suspension basket is developed by common Hanging Basket, and it is stressed to have increased interim drag-line on the basis of common Hanging Basket, thereby forms the composite force structure.The compound dragging suspension basket of short platform generally is made up of Hanging Basket platform, tripod and servo-drive system three parts.Hanging Basket main longitudinal grider front end is supported by interim drag-line in the work progress, the rear portion then anchoring with water on the sections, for reducing the crossbeam amount of deflection, increase the Hanging Basket lateral stiffness, the front beam centre position then adds the suspension rod of some by tripod according to bridge width.The advantage of this structure is owing to increased sulky derrick, therefore the front beam section can be less relatively, amount of deflection control is simple relatively, its shortcoming is that front beam is stressed comparatively complicated, because drag-line and suspension rod are simultaneously stressed, difficult in the work progress, and because suspension rod differs bigger with interim drag-line modulus of elasticity to the monitoring of Suo Li, therefore in stressed distribution, determine aspect the computation schema very difficulty.In addition, this structure is made up of Hanging Basket platform and tripod two cover systems, the structure relative complex, and weight is bigger.Moreover, because the Hanging Basket platform is shorter, thus its lateral stiffness a little less than.
The long platform dragging suspension basket has then broken away from the pattern of common Hanging Basket substantially, and its structure is made up of Hanging Basket platform and servo-drive system two large divisions, by anchor point and interim drag-line fixing Hanging Basket platform jointly.This cradle structure is simple, stressed clear and definite, the Load Transfer path of Hanging Basket is: sections weight concrete to be poured and working load are born by Hanging Basket platform rear portion anchor point and drag-line vertical force component, and the drag-line horizontal component is born by watering the sections girder by stopping device.The long platform dragging suspension basket is provided with the Hanging Basket platform under girder, and has become Hanging Basket land lengths under the beam section to be longer than Hanging Basket land lengths under the beam section to be poured slightly, made things convenient for the walking of Hanging Basket like this, guaranteed simultaneously Hanging Basket along bridge to rigidity.But because the long platform Hanging Basket does not have the sulky derrick system, thereby the control of crossbeam amount of deflection is difficult, and particularly for the bigger bridge of width, front beam is because span is bigger, and for reducing the front beam amount of deflection, its cross section needs relatively large.
In the prior art, the hauling-rope type Hanging Basket of prestressed concrete cable-stayed bridge construction mainly is made up of main truss support mechanism (being platform), template mechanism, guy rope mechanism, anchoring mechanism, height-regulating mechanism and running mechanism six parts.The main truss support mechanism of this Hanging Basket vertically is made up of four Pin universal rod body trusses, laterally connect by three Pin universal rod body trusses, and in the trusses leading portion certain limit of the outside, be provided with the anchoring chute that is connected with guy rope mechanism, the place is provided with the traveling bracket at middle trusses, make whole Hanging Basket by guy rope mechanism and anchoring mechanism, whole load in construction are passed in king-tower and having become on the beam section, after the construction of girder sections is finished, Hanging Basket is finished transfer by the travelling wheel on traveling bracket and the tail end crossbeam.For example, " the door cable stayed bridge hauling-rope type cradle construction new technology near a river " that people such as Chen Keji write, the 2nd phase of " bridge construction " nineteen ninety-five, the 68th page to 70 pages.It is that vertical load with Hanging Basket front end (that is platform front end) directly reaches the cable stayed bridge king-tower that the guy rope mechanism of this hauling-rope type Hanging Basket mainly acts on, act on vertical load on the cable-stayed bridge main-beam to reduce Hanging Basket, and this mode only provides an oblique fulcrum with guy rope to the Hanging Basket front end, can not play the transfer function of vertical load completely effectively, simultaneously because the relative flexibility of guy rope, make the Hanging Basket supporting still be the semi girder support pattern, therefore, the platform that makes Hanging Basket can only be the long platform with longer anchorage length, the platform that makes this Hanging Basket is from great, the counter-force of platform hook is bigger, cause cable-stayed bridge main-beam because of construction needs enlarging section, for making the amount of deflection of cast beam section meet the standard of construction, in hanging basket's components, increase nonvolatil structural meterials usually, and impel the deadweight of Hanging Basket to increase.
Summary of the invention
