[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0028] See also Figures 1 to 3 The utility model is a temporary asphalt pavement structure capable of quickly restoring traffic, comprising:

[0029] A steel base plate 1 for supporting asphalt;

[0030] The steel side plates 2 are arranged around the steel bottom plate 1 to enclose an asphalt containing space 3 with the steel bottom plate 1;

[0031] A mesh 4 of steel bars 41 is located in the asphalt containing space 3 and connected to the steel side plate 2;

[0032] The hoisting structures 5 are provided in two pieces, are located in the asphalt containing space 3 and are connected to the opposite ends of the steel base plate 1 .

[0033] When trenches need to be excavated to install pipelines, the utility model structure is prepared, asphalt is fully filled into the asphalt containing space of the structure, fully compacted and maintained, and a steel plate asphalt pavement is formed. During construction, the steel plate asphalt pavement is kept aside for standby. When not in construction, the steel plate asphalt pavement is hoisted onto the excavated pavement through a hoisting structure, which can quickly form a temporary vehicle passage, shorten the traffic interruption time, effectively relieve traffic pressure, and secondly, effectively protect underground pipelines to avoid damage to the pipelines caused by loads generated during vehicle driving.

[0034] In one embodiment, the steel bottom plate 1, the steel side plate 2, the steel bar 41 mesh 4, and the hoisting structure 5 are welded to form a whole. Such a design can form a stable whole structure.

[0035] In one embodiment, the steel side plate 2 is made of angle steel, and the material of the angle steel is Q235 steel. The angle steel is 100*100*10 equal angle steel, one side of which is tightly fitted around the steel bottom plate 1, and the other side is parallel to the excavation section, ensuring that the post-poured asphalt can form a whole after compaction and does not fall off.

[0036] In one embodiment, the steel bar 41 mesh 4 is composed of multiple transversely arranged and multiple longitudinally arranged steel bars 41. The steel bars 41 are threaded steel bars with a diameter of 16, made of HRB400, arranged 15 cm apart, welded on both sides to the angle steel to form a whole with the angle steel, connecting the angle steel into a whole, and acting as asphalt aggregate.

[0037] In one embodiment, the hoisting structure 5 includes two gate-shaped hangers 51 arranged at intervals. The gate-shaped hangers are used to connect the hoisting tools during hoisting.

[0038] In one embodiment, the hoisting structure 5 further includes a protective plate 52 arranged around the two gate-shaped hangers 51, and the top surface of the protective plate 52 is higher than the two gate-shaped hangers 51. The protective plate plays a role in protecting the gate-shaped hangers. Since the gate-shaped hangers have no lateral support, vehicles with heavy roads are prone to bend the gate-shaped hangers, and the protective plate surrounding the gate-shaped hangers can support the vehicles.

[0039] In one embodiment, the channel steel of the door-shaped hanger 51 is made of angle steel, and the channel steel of the door-shaped hanger 51 is a C8 channel steel with a thickness of 10 mm, made of Q235 steel, and connected to the steel bottom plate by welding, and the steel plate can be hoisted as a whole through its notch.

[0040] In one embodiment, the size of the steel bottom plate 1 is smaller than the size of the excavation, so that the steel bottom plate fits closely with the excavation section, ensuring that the steel bottom plate can fit closely with the excavation section after installation without sliding around. The steel bottom plate 1 is made of Q235 steel with a thickness of 20 mm, and plays a role in bearing the post-cast asphalt, and does not deform when the post-cast asphalt pavement is moved.

[0041] Specific implementation method: If a new underground pipeline is to be buried, the asphalt pavement needs to be excavated and the underground pipeline buried.

[0042] Step 1: Excavate the surface of the asphalt pavement according to the size of the steel plate, and then excavate the asphalt surface where underground pipelines need to be buried.

[0043] Step 2: Connect the steel plate, angle steel, steel bar and channel steel into a whole by welding.

[0044] Step 3: Use a crane to lift the steel plate as a whole to the site via wire rope.

[0045] Step 4: Lift the steel plate as a whole to the excavated asphalt pavement and place it steadily on the asphalt pavement, ensuring that the steel plate is stable as a whole during the lifting process.

[0046] Step 5: After the steel plate is placed stably on the asphalt pavement, the asphalt is fully filled into the steel plate, fully compacted and maintained to form a steel plate asphalt pavement.

[0047] Step 6: When pipeline construction is required, the steel plate asphalt pavement is hoisted aside through the channel steel. When the construction is no longer in progress, the steel plate asphalt pavement is hoisted onto the excavated road surface as a short-term vehicle passage.

[0048] Step 7: After the construction is completed, the steel plate asphalt pavement will be hoisted to other areas for recycling.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
