Embodiment Construction
[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0023] See Figure 1 to Figure 4 , The present invention provides a technical solution: an extensible concrete blocking device for road widening, comprising an old pavement body 1, a widening road 2 and a reinforcement member, between the side of the old pavement body 1 and the widening road 2. Connected by reinforcement members, the reinforcement members include an inner connecting plate 3, an outer blocking plate 4, a spacing adjustmen...

The invention relates to the technical field of road structures, and particularly relates to an extensible concrete blocking device for road widening. The extensible concrete blocking device comprisesan old pavement body, a widened road and a reinforcing member, the side edge of the old pavement body is connected with the widened road through the reinforcing member, the reinforcing member comprises an inner connecting plate, an outer blocking plate, a spacing adjusting rod set and a guide rod set. The extensible concrete blocking device has the beneficial effects that the side edge of the oldpavement body is connected with the widened road through the reinforcing member, the inner connecting plate in the reinforcing member is fixedly connected with a pre-embedded joint embedded in the side wall of the old pavement body, the old pavement body does not need to be damaged, the original structural performance of the old pavement body is retained, through the rotation of the nut end headat the outer end of an outer screw rod, the distance between the inner connecting plate and the outer blocking plate can be adjusted under the threaded connection relationship between the outer screwrod and an inner wire barrel, and the width of the widened road which needs to be poured is adjusted.
Description
Technical field [0001] The invention relates to the technical field of road structures, in particular to an extensible concrete blocking device for road widening. Background technique [0002] With the continuous development of urbanization, the traditional urban road construction and design requirements can no longer meet the increasing urban traffic flow. Therefore, the number of road widening and renovation 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, which is likely to cause cracks between the widened road and the old road. The structure is unstable. There is no obvious combination between the widened road and the old road. The method of re-digging holes and burying the connecting steel bars in the road will damage the original structure and make the construction difficult. Summary of the invention [0004] The purpose of the present invention is to provide ...
