Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 and fig. 2, the present invention provides a technical solution: the utility model provides a road bridge crack reinforced structure, including setting up crack 1 at bridge floor or ground, crack 1 is last to be provided with open slot 11, crack 1's bottom has inserted well core rod 12 and side bar 13 respectively, crack 1's bottom packing has bed course 14, bed course 14 is laid by the rubble, and it makes to fill the concrete mortar, be provided with cement mortar layer 15 on the bed course 14, be provided with polyurethane glue film 16 on the cement mortar layer 15, bed course 14 can regard as the basic unit, prevent that the condition of caving in from appearing in crack 1's bottom, cement mortar layer 15 plays a transition effect, can reduce polyurethane glue film 16's quantity simultaneously.

Referring to fig. 1, a steel plate 2 is laid in an open slot 11, the steel plate 2 is tightly attached to a center rod 12 and a side rod 13, the steel plate 2 is fixedly connected with the open slot 11 through expansion bolts, an asphalt layer 21 is laid on the steel plate 2, the upper end face of the asphalt layer 21 is parallel to the ground or a bridge floor, the steel plate 2 can play a supporting effect, and the asphalt layer 21 can be matched with the asphalt surface of the ground or the bridge floor.

Referring to fig. 1, 2 and 3, a mounting block 3 is welded on the central rod 12, a connecting plate 31 is connected to the mounting block 3 through a bolt, a support rod 32 is arranged on the connecting plate 31, and the support rod 32 is in contact with the inner wall of the crack 1, so that the middle part of the crack 1 with a large width can be reinforced and supported.

The utility model discloses when concrete implementation: when a crack 1 with a wider bridge deck or ground is required to be filled, firstly, a square open slot 11 is formed in the opening position of the crack 1 through a grooving machine, then, a plurality of central rods 12 and side rods 13 are sequentially inserted into the crack 1 and embedded into the bottom of the crack 1, the upper end surfaces of the central rods 12 and the upper end surfaces of the side rods 13 are parallel to the bottom surface of the open slot 11, then, a cushion layer 14 is firstly filled into the crack 1, the cushion layer 14 is paved by broken stones, then, concrete mortar is poured into the paved layer to fill gaps of the broken stones, meanwhile, the broken stones are gathered, the cushion layer 14 is ensured to reach a flat layer, after being dried, a cement mortar layer 15 is filled in the cushion layer 14 to be used as a transition layer and reduce the usage amount of a polyurethane rubber layer 16, after being dried, a connecting plate 31 with a support rod 32 is fixed with a mounting block 3 on the central rods 12, make the bracing piece 32 can carry out the support of inner wall to the part of crack 1 broad, bracing piece 32 can cut the adjustment according to actual width, lays polyurethane glue film 16 again, and polyurethane glue film 16 can play a sealed waterproof effect, treats the dry back, passes through the bolt fastening with steel sheet 2 and lays in open slot 11, supports through well core rod 12 and side pole 13 simultaneously.
