Problems solved by technology
[0005] In view of the above-mentioned related technologies, the inventor believes that when the asphalt pavement is laid, the upper end of the inspection well is higher than the ground layer, the asphalt will adhere to the side wall of the protruding end of the inspection well, and the asphalt will fall into the inspection well, causing the inspection well to be blocked. Make the post-construction of the inspection well difficult

The invention relates to the field of road construction, in particular to a composite asphalt pavement inspection well protection device and a pavement construction method. The composite asphalt pavement inspection well protection device comprises a top plate, a moving mechanism is arranged on the lower portion of the top plate, the moving mechanism is connected with a plurality of abutting plates, the moving mechanism drives the abutting plates to move, the abutting plates abut against the peripheral side of the side wall of the protruding end of the inspection well, a hollow baffle is arranged on the lower side of the top plate and surrounds the peripheral side of the side wall of the protruding end of the inspection well, a pressurizing piece is arranged on the baffle and used for compacting the baffle, and a vibration mechanism is arranged on the top plate. The device has the effects that the integrity of the side wall of the protruding end of the inspection well is protected, and later construction of the inspection well is facilitated.
Description
technical field [0001] The present application relates to the field of road construction, in particular to a composite asphalt pavement inspection well protection device and a road construction method. Background technique [0002] Asphalt pavement refers to various types of pavement paved with asphalt materials mixed with mineral materials. Asphalt binder improves the ability of paving aggregates to resist road damage from driving and natural factors, making the road smooth, less dusty, impermeable and durable. Therefore, asphalt pavement is the most widely used high-grade pavement in road construction. [0003] The asphalt pavement structure layer can be composed of surface layer, base layer, subbase layer and cushion layer. The asphalt structure layer of asphalt pavement itself belongs to the category of flexible pavement, but its base layer can also use rigid cement concrete or semi-rigid concrete in addition to flexible materials. hydraulic materials. [0004] The st...
