Abstract
The utility model discloses a novel wedge-shaped butt strap which relates to a bridge end transition butt strap. The novel wedge-shaped butt strap comprises a bridge abutment, a pavement structure layer, a bridge deck pavement layer, a bridge plate, a pavement fill subgrade layer and a butt strap, wherein the butt strap takes the shape of a wedge with gradually reduced volume from one end to the other end, and the butt strap is arranged between the pavement structure layer and the pavement fill subgrade layer. In the utility model, the butt strap takes the shape of the wedge with a short upper edge and a long lower edge; a flexible structure subgrade layer with good integrity and high rigidity is formed in a bridge end pavement transition region; and compared with the tension of the traditional butt strap, the tension of the novel wedge-shaped butt strap is changed from a point into a surface so that the tensile stress is reduced to the range capable of being accepted by a pavement, and the possibility that the pavement structure layer is fractured at the tail end of the butt strap is reduced; besides, the stable transition between the rigid bridge abutment and a flexible subgrade is realized, and the excessive differential subsidence is eliminated so as to form a gentle subsidence transition section to achieve the aim of preventing bumping at the bridge abutment.
Description
Technical field
The utility model belongs to building of bridge and viaduct and package technique field, relates in particular to a kind of soft patch of highway bridge of bridge pier, abutment of bridge member.
Background technology
Bumping at bridge-head is meant that road is out of shape with the road surface that is connected the zone appearance or the attachment strap of the bridge platform back of the body, fracture, even hole groove, thereby making vehicle ' be subjected to impacting the back through this zone takes place obviously to jump, jolt, bumping at bridge-head is one of common disease of highway, it also is a big technical barrier that always perplexs the highway industry for many years, not only have a strong impact on the comfortableness of driving, reduce the travel speed of vehicle and the traffic capacity of road, influence the use and the vehicle life-span of bridge, and can greatly increase the HIGHWAY MAINTENANCE maintenance costs, even initiation road traffic accident, produce bad social influence, grievous injury the economic and social benefit of high-grade highway, become urgent problem in the high-grade highway construction.
As shown in Figure 1; traditional general cross section of wedge shape attachment strap is shapes such as rectangle; lay such wedge shape attachment strap in the roadbed of abutment end; usually because near the ground the attachment strap is softer; make bridge foundation the sedimentation imagination occur, occur the harm of bumping at bridge-head like this on this road surface of vehicle ' through regular meeting as the fracture road surface 11 among Fig. 2.
The utility model content
The purpose of this utility model is to overcome existing attachment strap and occurs defectives such as bumping at bridge-head easily, and a kind of novel wedge shape attachment strap is provided, and can increase the bearing capacity of foundation soil in zone, end of the bridge road surface, can reduce or solve the harm of bumping at bridge-head effectively.
The purpose of this utility model is achieved through the following technical solutions:
A kind of novel wedge shape attachment strap comprises abutment, road surface structare layer, bridge deck pavement, beam slab, road surface made road basic unit and attachment strap, and attachment strap is the wedge-type shape of volume from an end to other end convergent, and attachment strap is arranged between road surface structare layer and the road surface made road basic unit.
In order to realize the utility model better, the axial cross section of described attachment strap is a trapezoidal shape.
As preferably, described attachment strap is short, the right-angled trapezium shape of the length of side down in top, and the right-angle side of attachment strap is arranged on the abutment.
The utility model is compared than prior art, has the following advantages and beneficial effect:
(1) attachment strap of the present utility model is the wedge-type shape of short, the following length of side in top, form good integrity, flexible structure base course that rigidity is big in end of the bridge road surface transitional region, the pulling force that is subjected to of more traditional attachment strap has become face by point, allow tensile stress reduce in the scope that to accept on the road surface like this, reduced the possibility of road surface structare layer in the terminal fracture of attachment strap.Realize the smooth transition of rigidity abutment and flexible roadbed, eliminated excessive differential subsidence, formed mild sedimentation changeover portion, reached the purpose that prevents abutment jumping car.
(2) this novel attachment strap has advantages such as bearing capacity of foundation soil is big, rigidity big, anti-impact is lost and corrosion resistance is good, ageing-resistant, the strength of materials is high, engineering cost is low, can promote the use of on abutment.
Description of drawings
Fig. 1 is the structural representation that traditional attachment strap is laid;
Fig. 2 is the structural representation when roadbed subsidence occurring after traditional attachment strap is laid;
Fig. 3 is a structural representation of the present utility model.
Wherein, the pairing name of the Reference numeral in the accompanying drawing is called:
The 1-road surface structare layer, 2-road surface made road basic unit, 3-attachment strap, 4-abutment, 5-beam slab, 6-bridge deck pavement, the 11-road surface of rupturing.
The specific embodiment
Below in conjunction with embodiment the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
Embodiment
As shown in Figure 3, a kind of novel wedge shape attachment strap comprises abutment 4, and a side of abutment 4 is a bridge floor, and opposite side is the road surface, and bridge floor comprises that the bottom is set works rigidity beam slab 5 that supports the frame-saw effect and the bridge deck pavement 6 that is layed in beam slab 5 tops; The road surface comprises road surface made road basic unit 2 and road surface structare layer 1, road surface made road basic unit 2 inside near abutment 4 the road surface transitional region are provided with attachment strap 3, attachment strap 3 is the wedge-type shape of volume from an end to other end convergent, and attachment strap 3 is arranged between road surface structare layer 1 and the road surface made road basic unit 2.
The attachment strap 3 of present embodiment is the right-angled trapezium shape of short, the following length of side in top, and the right-angle side of attachment strap 3 is arranged on the abutment 4, this novel attachment strap 3 is layed between road surface structare layer 1 and the road surface made road basic unit 2, can carry out subgrade strengthening to the zone, transition road surface of end of the bridge.Owing to be wedge-type shape, the pulling force that is subjected to of more traditional attachment strap 3 (as shown in Figure 1) has become face by point, allows tensile stress reduce in the scope that can accept on the road surface like this, has reduced the possibility of road surface structare layer 1 in attachment strap 3 terminal fractures.
In sum, just can realize the utility model preferably.
