Abstract
The present invention relates to a kind of have the anti-thrust force protection wall of end of the bridge without end carriage V-type rigid frame bridge; bridge pier is fixed with in the upper end of supporting pile; first battered leg and second battered leg is fixed with at the upper surface of bridge pier; bridge main roof beam structure is in the upper end of first battered leg and second battered leg; first battered leg and case beam are acute angle; second battered leg and case beam are acute angle; protection body of wall is provided with at the lower position of first battered leg; protection body of wall and first battered leg are non-interfering stress system, and the protection surface of wall adjacent with first battered leg is parallel to first battered leg.The present invention greatly reduces the detrimental effect of bridgehead filled soil to the firm structure of V-type, reduce the integral level thrust of the soil body to bridge, the moment of flexure of the root of battered leg is greatly reduced, also reduces the internal force at pier consolidation place simultaneously, and then add the safety of structure, decrease the consumption of reinforcing bar.
Description
Technical field
The present invention relates to a kind of without end carriage V-type rigid frame bridge, the present invention especially relate to a kind of have the anti-thrust force protection wall of end of the bridge without end carriage V-type rigid frame bridge.
Background technology
Along with the fast development of China's traffic and urban construction, people seek new bridge type to realize to cross over road and river.V-type pier continuous rigid frame bridge has vivid shapes, attractive in appearance, rich sporty feature, has become a kind of bridge type popular at present, compared with the traditional bridge type once used for many years, has become alternative a kind of superior solution.
V-type supports and adopts consolidation with the connection on basis, mainly increases rigidity and the resistance to overturning of structure, strengthens antidetonation, impact resistance.As hinged in adopted, the indeterminate adverse effect of structure can be improved, but hinge complex structure, rigidity is poor, therefore design normal employing consolidation system, because bridge adopts V-type pier, decrease span of bridge, thus reduce deck-molding.Compared with the continuous girder bridge of routine or continuous rigid frame bridge, the moment of flexure peak value of its span centre and fulcrum location obviously reduces, thus saves the material such as reinforcing bar, concrete, from another aspect, when other conditions are identical, the span ability of V-type rigid frame bridge is stronger.
V-type integral bridge rigidity significantly improves, particularly high pier structure, and the existence of V-type pier increases the rigidity near bridge fulcrum greatly, thus decreases span of bridge, reduces beam body amount of deflection.
V-type rigid frame bridge structure stress is comparatively complicated.Because bridge is multiple indeterminate structure, temperature, concrete shrinkage and creep and prestressed reinforcement all can cause second inner force.For the V-type rigid frame bridge without end carriage, resolve the horizontal thrust of bridgehead filled soil to battered leg, have practical meaning to bridge security.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of can reduce the soil body to the integral level thrust of bridge, also can reduce pier consolidation place internal force have the anti-thrust force protection wall of end of the bridge without end carriage V-type rigid frame bridge.
According to technical scheme provided by the invention, described have the anti-thrust force protection wall of end of the bridge without end carriage V-type rigid frame bridge, comprise supporting pile, bridge pier, first battered leg, second battered leg and case beam, bridge pier is fixed with in the upper end of supporting pile, first battered leg and second battered leg is fixed with at the upper surface of bridge pier, the length direction of first battered leg is perpendicular to the upper surface of the bridge pier connected with first battered leg, the length direction of second battered leg is perpendicular to the upper surface of the bridge pier connected with second battered leg, first battered leg is near end of the bridge, case roof beam structure is in the upper end of first battered leg and second battered leg, first battered leg and case beam are acute angle, second battered leg and case beam are acute angle, protection body of wall is provided with at the lower position of first battered leg, independent separately between protection body of wall and first battered leg, and the surface of the protection body of wall adjacent with first battered leg is parallel to first battered leg.
Gap between described protection body of wall and first battered leg is 1 ~ 4mm.
Described protection body of wall is formed by cemented rock or concreting.
The present invention greatly reduces the detrimental effect of bridgehead filled soil to the firm structure of V-type, reduce the integral level thrust of the soil body to bridge, the moment of flexure of the root of battered leg is greatly reduced, also reduces the internal force at pier consolidation place simultaneously, and then add the safety of structure, decrease the consumption of reinforcing bar.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described.
This have the anti-thrust force protection wall of end of the bridge without end carriage V-type rigid frame bridge, comprise supporting pile 1, bridge pier 2, first battered leg 3, second battered leg 4 and case beam 5, bridge pier 2 is fixed with in the upper end of supporting pile 1, first battered leg 3 and second battered leg 4 is fixed with at the upper surface of bridge pier 2, the length direction of first battered leg 3 is perpendicular to the upper surface of the bridge pier 2 connected with first battered leg 3, the length direction of second battered leg 4 is perpendicular to the upper surface of the bridge pier 2 connected with second battered leg 4, first battered leg 3 is near end of the bridge, case beam 5 frame is in the upper end of first battered leg 3 and second battered leg 4, first battered leg 3 is acute angle with case beam 5, second battered leg 4 is acute angle with case beam 5, protection body of wall 6 is provided with at the lower position of first battered leg 3, between protection body of wall 6 and first battered leg 3, there is gap, and the surface of the protection body of wall 6 adjacent with first battered leg 3 is parallel to first battered leg.
Gap between described protection body of wall 6 and first battered leg 3 is 1 ~ 4mm.
Described protection body of wall 6 is formed by building block stone and concrete slurry casting.
The present invention adopts below first battered leg 3, adds protection body of wall 6, and bridgehead filled soil and first battered leg 3 are separated by resistant slide, the overturning or slip resistance analysis function of utilization protection body of wall 6.The present invention according to the angle of first battered leg 3 by protection body of wall 6 the domatic 1:1 of making put domatic formula, make full use of protection body of wall 6 autostability, protect battered leg further.
