The invention relates to the technical field of road structures, in particular to an extensible concrete blocking device for road widening, which includes old pavement bodies, widened roads and reinforcement components, and the reinforcement components are passed between the side of the old pavement body and the widened road Connection, the reinforcing member includes an inner connecting plate, an outer blocking plate, a distance adjustment rod group and a guide rod group, beneficial effects: the side of the old pavement body and the widened road are connected by a reinforcing member in the present invention, and the inner connecting plate in the reinforcing member Through the fixed connection with the pre-embedded joints embedded in the side wall of the old pavement body, there is no need to destroy the old pavement body, and the original structural performance of the old pavement body is maintained. By rotating the nut end at the outer end of the outer screw rod, the outer screw rod Under the screw connection with the inner wire drum, the distance between the inner connecting plate and the outer blocking plate can be adjusted, which is used to adjust the width of the widened road that needs to be poured.
Description
technical field [0001] The invention relates to the technical field of road structures, in particular to an extendable concrete blocking device for road widening. Background technique [0002] With the continuous development of the urbanization process, the traditional urban road construction and design requirements have been unable to meet the increasing urban traffic flow. Therefore, the number of road widening and reconstruction projects has also shown a gradual upward trend. [0003] The structure between the traditional widened road and the old road is separated and relatively independent, and it is easy to cause cracks between the widened road and the old road, the structure is unstable, and there is no obvious combination of reinforcement between the widened road and the old road; The method of re-digging holes and embedding connecting steel bars on the road will cause great damage to the original structure and make construction difficult.
