Embodiment Construction

[0031] Such as figure 1 As shown, connecting hinge 1 3 and connecting hinge 2 4 connect the chain plate 1, transition plate 2 and cap (abutment) 5 into a continuous chain structure, and as the corresponding road surface, using hinge 1 3 and hinge 2 4 The settlement difference between the rotation adaptation cap (abutment) 5 and bridgehead embankment filling 9.

[0032] Such as figure 2 As shown, the bearing platform 5 and the chain plate 1 are connected by a connecting hinge 1 to prevent the chain plate 1 from falling away from the bearing platform 5. At the same time, when there is a bridge head settlement difference, the rotation of the hinge is used to ensure the continuity and smoothness of the road surface.

[0033] Such as image 3 As shown in the figure, the case of two chain transition structures is taken as an example to show the plane layout of the structural connection, and each chain transition structure is in accordance with figure 1 Connected, each column is ...

Abstract

The invention relates to highway engineering and construction engineering, in particular to a chain transition device adapted to building settlement difference for solving the problem of vehicle jumping at the bridge head, which is laid side by side on the bridge head or embankment at both ends of the culvert where the settlement difference is to be eliminated A number of chain transition structures, each row of chain transition structures are hinged by chain plates and several sections of transition plates; the device of the invention can adapt to the differential deformation between the bridge head, culvert and embankment like a chain, and always maintain the continuity and stability of the road surface. Smoothness, completely eliminate the poor settlement of the bridge head, and avoid the phenomenon of "jumping".

Description

technical field [0001] The invention relates to highway engineering and construction engineering, in particular to a chain transition device adapted to building settlement difference for solving the problem of vehicle jumping at the bridge head. Background technique [0002] In construction engineering, due to the difference in deformation stiffness between two adjacent structures, there is often a difference in settlement, which seriously affects their function. The most typical example is the phenomenon of "jumping at the bridge head" caused by the settlement difference between the bridge head and the junction of the culvert and the embankment in highway traffic. Because bridges and culverts (often using pile foundations) have high deformation stiffness and small settlement, embankments are built on foundations with small deformation stiffness and large settlement, resulting in poor settlement and "jumping at the bridge head". The "bridge head jumping" phenomenon caused b...
