Abstract
The invention discloses a deck type arch bridge vault padding unloading and reinforcing construction method and application. By means of the construction method and the application, the situation that collapse is caused by unbalanced loading and unloading of a deck type arch bridge in the repairing and reinforcing process of the bridge is prevented. The construction method is characterized by including the following steps that a bridge floor is divided into an odd number of working faces from the center to the two sides of the bridge floor in the length direction of a bridge, and the width of each working face is 1000-3000 mm; firstly, the working face in the center of the bridge floor is excavated, bridge deck pavement and vault padding are unloaded, the arch back is cleaned, and a main arch ring and spandrel arch diseases are repaired and removed through slurry; afterwards, a mould is erected, and an excavated face is backfilled with plain concrete; and then the working faces on the two sides of the working face in the center are sequentially excavated until all the working faces are constructed according to the construction process and requirements of the working face in the center. By means of the construction method and the application, the deck type arch bridge can be repaired and reinforced under the condition that most structures of the original arch bridge are not changed, and construction is safe, reliable and simple; and meanwhile, the backfilling plain concrete is tightly combined with the main arch ring and spandrel arches, the thicknesses of the main arch ring and the spandrel arches are correspondingly increased, the reinforcing effect is achieved, and the construction engineering quality is improved.
Description
Technical field
The present invention relates to reparation and the reinforcing of a kind of arch bridge, specifically a kind of Deck Arch Bridges vault filler unloading and reinforced construction method and application, particularly relate to a kind of prevent bridge unloading in Deck Arch Bridges repairing and reinforcement and load the unbalanced Deck Arch Bridges vault filler unloading causing subsiding and reinforced construction method and application.
Background technology
Deck Arch Bridges includes masonry arch bridge, arch bridge with reinforced concrete slabs, double curvature arched bridge etc., and this structure type bridge is relatively wide in China's application, and particularly masonry arch bridge has nearly one thousand years history.In China's the 1950's～the eighties, along with economic development, the extensive application of armored concrete, wherein double curvature arched bridge was promoted rapidly in the seventies, and this structure has given full play to construct feature easily, saves steel, it is simple to draw materials, be greatly accelerated construction speed.But, operation through decades uses, along with developing rapidly of highway communication, vehicle density and the accumulation being continuously increased with the aging of material and structural damage of overloaded vehicle, it is low to there is design grade in the Deck Arch Bridges in addition built before the eighties, at present, bridge has occurred obvious disease and mass defect, there is serious potential safety hazard.To this, generally it need to be carried out consolidation process.Owing to the arch ring of the most most of arch bridge of this kind of bridge deforms, cause original design linear and pressure line generation large change, so that when repairing construction, owing to construction unloading is unbalanced or Large Construction facility use, it is easily caused main arch compressive region reduce and unload unbalanced with loading, bridge collapse phenomenon occurs.
Summary of the invention
It is an object of the invention to provide and a kind of in Deck Arch Bridges repairing and reinforcement, prevent bridge unloading and load the unbalanced Deck Arch Bridges vault filler causing subsiding unloading and reinforced construction method and application.
The present invention adopts the following technical scheme that and realizes its goal of the invention, and a kind of Deck Arch Bridges vault filler unloading and reinforced construction method, it comprises the following steps:
(1) to both sides, bridge floor being divided odd number work surface from deck centre according to the length direction of bridge, the width of each work surface is 1000～3000；
First excavation deck centre work surface, unloading deck paving and vault filler, carries out hogback cleaning, and seat slurry repairs main arch ring and spandrel arch disease；
The most then formwork erection plain concrete backfills excavation face；
(4) fill concrete maintenance, makes intensity reach design strength 65～75；
Excavate the work surface of surface both sides the most successively, construct, until all working surface construction is complete by surface work progress and requirement.
The present invention step (1) in, the width of the work surface of surface both sides is identical.
During for making excavation, the change of former bridge original structure longitudinal stress is affected the lateral stressed change equilibrium of little and former bridge, the present invention step (5) in, the work surface of the described surface both sides of excavation successively is that first excavation and surface are separated by the work surface of a work surface.
For ensureing the globality of successively casting concrete, occurring without construction joint, the joint face between the plain concrete of work surface of the present invention backfill carries out wharf's pavement quality.
For ensure successively casting concrete globality and lateral stressed uniformly, be provided with power transmission muscle between the plain concrete of work surface of the present invention backfill, arrange by spacing 250～350, a diameter of the 10～20 of described power transmission muscle, a length of 150～250.
The unloading of a kind of Deck Arch Bridges vault filler described above and reinforced construction method application in Deck Arch Bridges repairing and reinforcement.
Deck Arch Bridges of the present invention is masonry arch bridge or arch bridge with reinforced concrete slabs or double curvature arched bridge.
Owing to using technique scheme, the present invention preferably achieves goal of the invention, change the strict unloading of tradition and loading procedure, in the case of former arch bridge major part structure is motionless, Deck Arch Bridges can be carried out repairing and reinforcement, and use plant equipment multiple spot multistage operation, alleviate the labor intensity of workmen, improve production efficiency, and without spandrel arch circle being installed the support of falsework equipment during construction, save cost, construction safety is reliable, simply, simultaneously, the plain concrete of backfill and main arch ring, spandrel arch is tightly combined, add main arch ring accordingly, spandrel arch thickness, reach consolidation effect, improve construction project quality.
