Abstract

A road-bridge transition section roadbed settlement test platform includes a left retaining wall at the left of the foundation stratum, a right retaining wall at the right, ribbed panel bridge abutment at the front, a front retaining wall and a gravity bridge abutment and a rear retaining wall, at least 95 uprights are set on the foundation stratum with a jack on each top, a support supporting a movable settlement plate is set at the top of the jack, a left concrete panel is set on the left of the top surface, and a right cement concrete panel is set at the right between the right and left retaining walls. The test plat form is connected with computer and power control system by cables to timely control its settlement, rate and its final settlement curves.

Description

technical field [0001] The invention belongs to the technical field of auxiliary equipment for building, repairing, repairing or demolishing roads or similar pavements, and in particular relates to equipment or devices for veneering, which can measure the shape of the pavement and add materials in proportion to the measured unevenness of the pavement device of. Background technique [0002] The road-bridge transition section is a high-incidence area for road diseases, and "jumping at the bridge head" is an intuitive manifestation of this disease. The "jumping at the bridge head" phenomenon in the expressway not only greatly affects the comfort of driving, but also reduces the traffic capacity of the road. Moreover, it is one of the important hidden dangers of road traffic safety, which has seriously affected the social image and social benefits of expressways. [0003] Over 10,000 kilometers of highways have been built in the country, and the phenomenon of "jumping vehicles...
