Description

TECHNICAL FIELD [0001] The present invention relates to a road packaging method using crack prevention and planarization equipment,

The present invention relates to a road pavement method using a crack prevention and planarization equipment, and more particularly, to a road pavement method using a crack prevention and planarizing device for preventing and planarizing a road surface when paving and repairing a concrete road such as a sidewalk, To road paving methods using planarization equipment.

In modern society, concrete is the most commonly used building and civil engineering material. In terms of road pavement, concrete pavement is the ideal road pavement method considering long-term, functional and efficient aspects.

Concrete is a multi-phase inorganic composite which forms a cured body by using hydration reaction of cement, water, and aggregate, and has a disadvantage in that it has a large unit mass, but has an advantage of being excellent in rigidity and efficiency. Concrete pavement is composed of concrete slab, middle layer and auxiliary layer. The concrete slab is used for direct traffic and it is the most important layer to support the load. In order to reduce the stress due to temperature change and water content change, It may be installed at intervals, or the cross section may be thickened. The auxiliary layer supports the concrete slab and disperses the traffic load transferred from the slab and transfers it to the hearth. Materials with good durability and sufficient bearing capacity are used.

Concrete pavement life is 30 ~ 40 years, compared with asphalt pavement (10 ~ 20 years), it is durable, easy to construct and easy to maintain. However, it is expensive and partial maintenance is difficult. This is a disadvantage.

Generally, for concrete road pavement, a concrete curing space is set up by installing a material separator appropriate to the width of the road. After placing 100 ~ 200mm of concrete in the curing space, the work surface is made flat and hard so that various types of standing finishing materials are used for flatness, and the work of finite part, boundary stone, .

In addition, the finish of the work prevents the rapid evaporation of water on the surface of the concrete, induces continuous wet curing, and spreads the vinyl for the purpose of preventing cracks and cracks due to drying shrinkage.

After the concrete curing, the concrete is cracked by shrinkage joints and expansion joints for the purpose of inducing the drying shrinkage of the slab, the expansion due to the temperature change, the reduction of the stress to the shrinkage twisting phenomenon and the irregular crack to a certain position .

Cracks of large cracks can be divided into material drying, construction conditions, environmental conditions, use conditions, structural conditions, and external force conditions. Hydration caused by chemical reaction between cement and water, which is a cracking factor in materials, (Cracking) caused by cracks and water shrinkage (rapid drying) due to excess tensile strength of concrete due to volume change caused by volume change, and cracking caused by bulging of material separating band (side pressure or impact) A factor has arisen.

As mentioned above, in order to finish the road pavement material, various kinds of equipment must be used. The structure and usage of such an apparatus will be described in detail below with reference to other drawings.

2 and 3 are perspective views of a material separator according to the present invention.

 That is, when the road is packed using the road pavement method using the crack prevention and planarization equipment according to the present invention, first, a pair of longitudinal material separators 101 and a pair of longitudinal material separators 101 A plurality of transverse stretching grooves 102 are formed across the longitudinally divided material dividing rods 102 across the material separating table 100 and the road paving material 1 is laid on the material separating table 100 at step S20. The plurality of transverse expansion joints 102 constitute the width of the road so that roads can be installed or repaired.

In addition, a scale 101a is displayed on the upper surface of the pair of longitudinal material dividing rods 101, and a manufacturing position of the extending grooves 550 to be described below can be displayed.

As shown in Fig. 1, the pair of longitudinal material dividers 101 are provided so as to correspond to each other so as to form a width of a road to be newly installed, and provide a curing space for the road pavement 1 therein. Wherein the pair of longitudinal material separators 10 are formed in a beam shape so as to form the width of the road and to be fixed by the fixing pin 101b.

The plurality of transverse expansion joints 102 are formed to cross the pair of longitudinal material dividers 101. The transverse expansion joints 102 provide the cushioning space for the road pavement material 1 every 25 m do

In addition, the plurality of transverse stretching grooves 102 are formed in a shape having an inner space opened on the upper side, that is, a cross-sectional shape, and the inner space is filled with a sponge-like filler 103.

The filler (103) prevents foreign matter from entering and acts as a buffer when expanded in the process of drying the road pavement (1), thereby preventing cracking and breakage.

The second step S20 is a step of installing the road pavement material 1. The road pavement material 1 may use various road pavement materials such as concrete, cement and loess, but is not limited thereto, It is irrelevant to the road wrapping material 10 used for packaging.

[

When flattening the lateral side surface of the road wrapping material 1 using the third compaction equipment 400 is completed by using the fourth compaction equipment 500 as shown in FIG. 12, The elastic shafts 550 are formed.

As shown in FIG. 12, the second projecting portion 520 of the fourth compaction equipment 500 simultaneously creates the expansion grooves on the upper surface of the road pavement material and the upper surface of the road pavement material 1 at the same time.

The reason why the second projecting portion 520 of the fourth compaction equipment 500 processes the expansion grooves 550 on the upper surface of the road pavement 1 is that the expansion of the road pavement 1 If the rainwater falls on the upper surface of the road wrapping material 1 and flows down to the extending groove 550, the groove 50 can obtain the effect of the drainage path.

The extensible grooves 550 are manufactured at an interval of 4 to 5 m and are manufactured within a range of 4 to 5 per 25 m of the new road. If it is more than the above range, inconvenience of a pedestrian may be caused, and the range is appropriate.

When the creation of the expansion grooves 550 of the road wrapping material 1 using the fourth compaction equipment 500 is completed, as shown in FIG. 13, the fifth compaction equipment 600 is used to form the upper surface .

The reason why the upper surface of the road wrapping material 1 is scratched by the fifth compaction equipment 600 is that it can help the user to walk or bike when the rain falls in the winter season and the summer season.

When the scratching of the upper surface of the road wrapping material 1 using the fifth compaction equipment 600 is completed, the curing and longitudinal material separator 101 is removed as shown in Fig.
