Description
Technical Field
The utility model relates to a plate structure improves technique for assembled road surface, especially assembled bridge deck pavement maintains cement road surface plate.
Background
At present, the cement pavement types of roads of various grades comprise common cement concrete, reinforced concrete, roller compacted concrete and continuous reinforced concrete, and all the types are cast-in-place construction. The method has long maintenance period and is not beneficial to quickly opening traffic.
The bridge pavement directly bears vehicle load and environmental corrosion, and the damage is more frequent. The traditional maintenance method mainly comprises the steps of chiseling out a damaged pavement layer, and then re-constructing a new pavement layer structure, so that traffic construction is often required to be closed, and the comprehensive social cost is very high under the background of heavy traffic.
The simple and easy method is to prefabricate the paving plate, pave the road surface or while maintaining and maintaining, can carry on the construction fast, but the prior art has not disclosed similar technology and product.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an assembled bridge deck pavement maintenance cement road surface plate, convenient quick maintenance road surface solves prior art problem.
The purpose of the utility model is realized by the following technical measures: an assembly type bridge deck pavement maintenance cement pavement plate comprises a concrete base surface; a plane reinforcing plate with reinforcing bars is fixed in the concrete base surface; the top surface of the concrete base surface is provided with a first layer of sizing material, and the surface of the first layer of sizing material is provided with a first layer of aggregate.
In particular, a plane reinforcing plate with reinforcing bars is horizontally fixed in the middle of the inner surface of the concrete base.
In particular, a second layer of sizing material is arranged on the surface of the first layer of aggregate, and a second layer of aggregate is arranged on the surface of the second layer of sizing material. The top surfaces of the first layer of sizing material, the first layer of aggregate, the second layer of sizing material and the second layer of aggregate are provided with thin layer pavement. The total thickness of the first layer of sizing material 2, the first layer of aggregate, the second layer of sizing material and the second layer of aggregate is 5-7 mm; wherein the total thickness of the first layer of sizing material and the first layer of aggregate is 2-3mm, and the total thickness of the second layer of sizing material and the second layer of aggregate is 3-4 mm.
Especially, the plane cloth muscle reinforcing plate adopts square grid column structure.
The utility model discloses an advantage and effect: the prefabricated slab block structure is convenient for production, storage, transportation and pavement, is suitable for further thin-layer pavement on the surface, has short construction period and low cost, and is suitable for light-load traffic. The construction method can realize rapid construction, and has the advantages of skid resistance, wear resistance, good durability and little damage to the old bridge structure. Can quickly recover traffic and has better comprehensive benefit.
