Description
Technical Field
The utility model relates to a formula of pouring asphalt concrete technical field, concretely relates to substitute concreting asphalt concrete who mats formation layer.
Background
The asphalt concrete pavement on the surface of the bridge needs to be repaired after the service life of the asphalt concrete pavement reaches, however, in the process of reconstructing a traditional pavement structure, the bridge is damaged, for example, the load of the bridge is increased in the rolling process, and meanwhile, the metal structure of the bridge is corroded.
SUMMERY OF THE UTILITY MODEL
The utility model provides a substitute concreting asphalt concrete on layer of mating formation, this structure can realize through pouring the technology of paving, not only prevents the corrosion of anchor reinforcing bar behind the bridge, need not to roll moreover, reduces the bridge dead weight, has increased bridge life, reduces the maintenance cost.
In order to achieve the above object, the utility model provides a following technical scheme: a cast asphalt concrete for replacing a concrete pavement, comprising: a concrete base layer; the resin seal layer is coated on the top of the concrete base layer; the fine sand layer is arranged above the resin seal layer; a waterproof bonding layer disposed over the fine sand layer; and the asphalt concrete is paved above the waterproof bonding layer.
Preferably, the top of the concrete base layer is a horizontal surface, and the top is a rough structure.
Preferably, the resin sealing layer is epoxy resin, and the thickness of the resin sealing layer is 1-2 mm.
Preferably, the thickness of the fine sand layer is 2-5 mm.
Preferably, the waterproof bonding layer is an AMP waterproof adhesive.
Preferably, the asphalt concrete is cast asphalt concrete GA-10.
The utility model discloses beneficial effect does: through a formula of pouring asphalt concrete who replaces concrete pavement layer in the renovation of bridge deck pavement, its complete set technique is ripe, and the process is simple, and convenient operation need not rolling equipment, reduces the bridge dead weight, and formula of pouring asphalt concrete 5's from dense type prevents the corrosion of anchor bar behind the bridge, increases the life of bridge, reduces the pollution of abandonment building rubbish to the environment, prolongs bridge maintenance cycle, reduces cost of maintenance.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
Fig. 1 is a schematic view of the pavement structure of the present invention.
Detailed Description
The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings of the present invention, and obviously, 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 efforts belong to the protection scope of the present invention.
According to fig. 1, a cast asphalt concrete for replacing a concrete pavement layer comprises: a concrete base layer 1; the resin seal layer 2 is coated on the top of the concrete base layer 1; the fine sand layer 3 is arranged above the resin seal layer 2; the waterproof bonding layer 4 is arranged above the fine sand layer 3; and the asphalt concrete 5 is paved above the waterproof bonding layer 4, and the asphalt concrete 5 is poured asphalt concrete GA-10.
The structure in the aforesaid is used for carrying out the renovation to the concrete bridge face, in the construction:
firstly, removing an aged and worn asphalt pavement on the surface of a bridge until a concrete structure of the bridge is exposed;
performing chiseling treatment on the upper surface of the bridge concrete structure to establish a rough concrete base layer;
thirdly, coating epoxy resin on the surface of the rough concrete base layer to form a resin seal layer;
covering fine sand on the resin seal layer to form a fine sand layer;
step five, coating a waterproof adhesive on the fine sand layer;
and step six, paving asphalt concrete on the waterproof adhesive.
The construction method is suitable for the renovation operation of bridges or common pavements, the operation process is simple and convenient, the technology is mature, and rolling equipment is not needed, so that the load on the roadbed or the bridges is reduced. In addition, in the construction of the bridge, the self-sealing property of the pouring type asphalt concrete 5 can prevent the corrosion of the anchor steel bars behind the bridge, prolong the service life of the bridge, reduce the pollution of waste building rubbish to the environment, prolong the maintenance period of the bridge and reduce the maintenance cost.
The rough structure on the top of the concrete base layer 1 increases the adhesive force between the resin seal layer 2 and the paving layer 1, and the degumming and separation phenomena are not easy to occur.
The resin seal layer 2 is made of epoxy resin, the thickness of the resin seal layer 2 is 1-2 mm, the epoxy resin with the thickness can effectively cover the top of the pavement layer 1, and omission is avoided.
The thickness of the fine sand layer 3 is 2-5 mm, the fine sand layer is used for increasing the friction force of an internal structure, the waterproof bonding layer 4 is an AMP waterproof bonding agent, the waterproof bonding layer 4 permeates into the fine sand layer 3, a waterproof structure is formed, the fine sand layer 3 has a good locking effect on the waterproof bonding agent, flowing around is avoided, and the covering area of the waterproof bonding layer 4 is effectively restrained while materials are saved.
Through a formula of pouring asphalt concrete who replaces concrete pavement layer in the renovation of bridge deck pavement, its complete set technique is ripe, and the process is simple, and convenient operation need not rolling equipment, reduces the bridge dead weight, and formula of pouring asphalt concrete 5's from dense type prevents the corrosion of anchor bar behind the bridge, increases the life of bridge, reduces the pollution of abandonment building rubbish to the environment, prolongs bridge maintenance cycle, reduces cost of maintenance.
The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
