Abstract

The utility model discloses an anti-settling bridgehead slope structure. The anti-settling bridgehead slope structure comprises a bridge abutment, a bridge embankment, bridge piers, road foundation stones, an reinforced slope and a road surface layer, wherein the reinforced slope is connected with a longitudinal reinforcing steel bar of the reinforced bridge slope by virtue of a pre-embedded exposed reinforcing steel bar head on the bridge embankment by welding, and poured with concrete to form an integral structure. The anti-settling bridgehead slope structure has the characteristics that the reinforced slope is integrally connected with the bridge embankment, so that the settling hidden dangers of the bridge slope are eliminated, and a step phenomenon of settling drop does not appear between the bridge abutment and the slope, a bridgehead bumping phenomenon appearing in a vehicle upgrading and downgrading process is eliminated, the service life of the bridge slope is prolonged; and meanwhile, the maintenance cost for excavating and repairing is also saved.

Description

A kind of anti-settling end of the bridge ramp structure

Technical field

The utility model relates to highway engineering, specifically is used for solving a kind of anti-settling end of the bridge ramp structure of problem of bumping at bridge-head.

Background technology

At present, in highway bridging engineering, because the pile foundation of bridge has solid basis, and the bridge two ends are often except the upper strata is the sandstone cement admixture, ground is the soil matrix of nature, make the sedimentation at settling ratio bridge two ends of bridge come fewly, so, tend to occur the phenomenon that the sedimentation drop appears in bridge table top two ends and the zone that it is connected mutually, add percussion when passed through by vehicle, make the sedimentation at bridge two ends be on the rise, and to the phenomenon that step occurs, brought potential safety hazard to traffic, thereby have to take excavation to be repaired, this had both influenced normally and had been open to traffic, and increased maintenance cost again.

Summary of the invention

The utility model provides a kind of end of the bridge ramp structure of anti-settling for fear of above-mentioned existing in prior technology weak point, makes not produce the step phenomenon that causes because of sedimentation between road surface, end of the bridge two ends and end of the bridge, fundamentally solves the phenomenon of bumping at bridge-head.

The utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of anti-settling end of the bridge ramp structure, comprise abutment, Qiao Di, bridge pier, roadbed stone, strengthen slope, supercrust, described reinforcement slope is welded and fused by the pre-buried exposed steel bar head on the bridge dike and the longitudinal reinforcement of strengthening the bridge slope, and become overall structure with concrete casting, form the slope at end of the bridge two ends.

Described reinforcement bridge comprises longitudinal reinforcement and transverse reinforcement in the slope, has galvanized wire to be bundled into one each other.

Described longitudinal reinforcement becomes whole reinforcement bridge slope and the transition of abutment interplanar camber with transverse reinforcement and concrete casting, the slope is descending gradually locating away from the abutment plane, forms hard relatively road structure.

The steel bar end of reserving when the pre-buried exposed steel bar head on the described bridge dike is pouring bridge dike.

Compared with prior art, advantage of the present utility model is, because being welding, the reinforcing bar on the bridge dike at end of the bridge two ends and the reinforcing bar on end of the bridge slope be linked to be an integral body, and it is whole with concrete casting one-tenth, form relative hard road structure, even roadbed has sedimentation, the step phenomenon that the sedimentation drop also can between abutment and slope, not occur, eliminated the bumping at bridge-head phenomenon that vehicle occurs when the bridge climb and fall, guaranteed the safety of driving, improve the application life on bridge slope, omitted the maintenance cost that excavation is repaired.

The specific embodiment

Describe in further detail below in conjunction with the utility model of accompanying drawing embodiment.

As shown in Figure 1 and Figure 2, a kind of anti-settling end of the bridge ramp structure comprises abutment 1, bridge dike 2, bridge pier 3, roadbed stone 4, strengthens slope 5, supercrust 6, and bridge dike 2 is built on bridge pier 3, and bridge dike 2 is provided with pre-buried exposed steel bar head 21, and abutment 1 is laid on the bridge dike 2.

Longitudinal reinforcement 51 integrally welded structures under pre-buried exposed steel bar head 21 on the bridge dike 2 of the present utility model and the reinforcement slope 5, strengthening slope 5 is integral with the galvanized wire colligation after by longitudinal reinforcement 51 and transverse reinforcement 52 mutual cross arrangements each other, water with concrete 53 again, form relative hard road structure, avoided in the past dividing because of bridge dike or abutment and slope the phenomenon of the slope sedimentation that body structure causes.

The utility model is filled with roadbed stone 4 below strengthening slope 5, at abutment 1, bridge dike 2 and strengthen above the slope 5 integral body layer overlay supercrust 6 smoothly, and be connected transition with level road is smooth.

The utility model in other embodiments, abutment 1 can also carry out scene pouring with steel concrete.

Above-described embodiment is of the present utility model a kind of, also is applicable to culvert, cable stayed bridge, suspension bridge etc., is not the restriction to the utility model rights protection.
