Description

[Detailed Description of the Invention] Fields of Application of Soil Collection The present invention relates to a paving method, and in particular to a method for paving dam structures, concrete pavements, etc., and for reliably repairing damaged areas with high workability. Regarding possible paving methods.

<Conventional technology> In order to repair damage to the apron of a dam or the surface of concrete pavement, or to smoothen the surface of concrete pavement, a fluid paving material is poured onto these surfaces. The method used is to level the surface with a vibrating beam (ruler) to create a smooth surface. In this construction method, the beam is supported by a pair of guides installed at each end of the construction surface. Conventionally, these guides are: ■ Wooden formwork fixed with concrete nails ■ Metallic formwork fixed with support brackets. There is a method of using a wooden board or rod-shaped member.

<Problem to be solved by the invention> However, in all of these methods, the construction surface usually has irregularities of large and small sizes, so a gap is created between the construction surface and the guide, and fluidity is lost through this gap. The paving material that is in the tank will flow out. Particularly when a highly fluid paving material is used, this outflow is a serious problem. In addition, in method (2), the vibrations applied to the beam may cause the concrete nails fixing the formwork that serve as guides to come off, or the concrete nails become an obstacle to the movement of the beam, resulting in poor workability.

Method (2) requires time to attach the support fittings, resulting in poor workability.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a paving method that can reliably pave a paved surface such as concrete paved surface and repair damage with high workability.

Furthermore, the present invention provides a second embodiment of a method for paving the outside of an already paved area, in which grooves are bored in the construction surface to be paved, and the legs of the guide member are planted in the grooves. After arranging the leveling member guide portion of the guide member to a predetermined level, pour paving material between the guide member and the paved area, and place the leveling member along the leveling member guide portion of the guide member. The present invention provides a paving method including a step of moving the paving material by moving the paving material to finish the upper surface of the paving material into a desired shape.

The paving method of the present invention will be explained in detail below.

Here, in the present invention, "paving" refers to paving of dam structures, concrete paved roads, etc., repair of damaged parts of these paved surfaces, floor paving of buildings such as factories, or damaged floors of these. This refers to the process of forming a surface such as a floor or road surface into a predetermined shape, such as when repairing.

The main steps for repairing damage to a concrete pavement surface based on the first embodiment of the present invention are shown below in Figure 1 (A
) to (D), the present invention will be explained in detail.

First, as a pretreatment before repairing a damaged pavement surface, it is recommended to use shot blasting or other surface treatment equipment to remove foreign objects on the pavement surface and deteriorated layers of the pavement. Also, even if shot blasting etc. is used,
Areas where foreign objects cannot be treated, road markings, etc.
It may be removed using an appropriate means such as a marking line remover.

Furthermore, after surface treatment, it is advisable to remove the joint filler filled in the joints of the paved surface.

The joint material may be removed using a processing machine such as a joint material removal device, or manually depending on the situation.

Next, mark both the left and right edges of the pavement surface to be repaired, draw parallel lines, and follow the lines as shown in Figure 1 (A).
A pair of grooves 2 and 3 are bored at both left and right ends of the pavement surface 1 to be repaired.

The trenches may be formed using a suitable cutting machine, such as a concrete cutting machine.

In addition, the grooves to be drilled are not particularly limited, but usually,
It may have a depth of about 15 to 20 mm and a width of about 6 mm.

After drilling the grooves 2 and 3, the surface of the pavement and the inside of the grooves 2 and 3 are cleaned to remove dirt, sand, etc., and then a brimer is applied to the surface.

At the same time, it is preferable to apply a thin coat to the inner surfaces of strips a2 and 3 in terms of adhesion to the base.

The brimer to be used may be appropriately selected from, for example, MMA (methyl methacrylate), epoxy, polyester, etc., depending on the paving material to be applied. The application amount of this brimer is, for example, 40
It is about 0 g/cm2.

Next, as shown in FIG. 1(B), a pair of guide members 5 and 6 are planted in each of the grooves 2 and 3 and fixed at a predetermined level.

This guide member may be made of iron or wood. Moreover, its shape is not limited to the inverted shape shown in FIG. It is sufficient as long as it has a support part that allows
For example, the cross section may be alphabetical, T-shaped, or horizontally 1 character-shaped.

The upper surfaces of the guide members 5 and 6 at both ends may be at the same level, or their heights may be adjusted relative to each other in order to obtain a finished surface with a constant slope. For example, normally a paved road has a swollen shape at the center, but in FIG. If the surface is finished, the pavement can have a cross-sectional shape in which the guide member 5 side is higher.

Further, in order to strengthen the guide member, as shown in FIG. good.

Next, as shown in FIG. 1(C), the paving material 11 is poured into the recess between the guide members 5 and 6.

The paving material to be used is not particularly limited and may be any material used for this type of paving. Examples include concrete, mortar, resin concrete, and the like. In particular, paved roads, factory floors, etc., which must be closed off to traffic at night and made passable the next day, harden quickly (and can be used immediately) after repair. Highly adaptable to resin concrete.

Next, while the paving material 11 is still uncured, the leveling member 12 is bridged between the guide members 5 and 6 as shown in FIG. 5
and 6, for example in the direction of the arrow, the surface of the paving material 11 can be smoothed and finished into a smooth or desired shape.

The material of the leveling member used is not particularly limited, and examples include metals such as iron and aluminum, wood, and plastic. Further, the cross-sectional shape is not particularly limited, and may be appropriately selected depending on the construction situation, such as opening, square, or L.

A smooth surface can be obtained by using parallel plate-shaped leveling members.

The vibration of the leveling member 12 may be applied by human power or power, and may be appropriately selected depending on the situation such as the size of the construction site and the presence or absence of a machine installation location.

Also, you can use a trowel to finish small areas that cannot be reached with leveling materials.

Next, by allowing the paving material 11 to harden, a smooth surface or a surface having a desired shape can be formed and the repair can be completed.

In the method shown in FIG. 1 described above, a pair of grooves are bored parallel to each other, and the guide members 5 and 6 are arranged parallel to each other, but the method of the present invention is not limited to this. The construction surface can be effectively paved by appropriately selecting the form of trench grooves and the arrangement of the guide members according to the shape of the construction surface to be constructed.

For example, a pair of grooves 2 and 3 may be bored non-parallelly, guide members may be placed therein, and paving may be carried out in the same manner as shown in FIG. 1 above.

Furthermore, in the first embodiment of the present invention shown in FIG. The present invention is not limited to this, but also provides a second embodiment of the present invention in which a groove is bored on one side of the construction surface of the pavement and a guide member is disposed in the groove.

Hereinafter, based on the second embodiment of the present invention, on a paved road where the sidewalk is one step higher than the roadway, the process of repairing damage to the pavement surface of the roadway will be explained in Figures 3 (A) to (D). )
The present invention will now be described in detail.

First, in the same way as the method of the first embodiment, as pre-treatments, the pavement surface is prepared and the joint material is removed.

In addition, in the following process, the groove drilling method, the depth and width of the groove, the brimers used, the material of the guide member,
The shape, reinforcement of the guide member, material of the paving material, leveling member, shape, method of applying vibration, etc. are the same as in the first embodiment, and therefore description thereof will be omitted.

Next, mark the outer edge of the pavement surface to be repaired and draw a line where grooves will be drilled, and follow the line as shown in Figure 3 (A).
As shown in the figure, there are lines on the pavement surface 21 of the road to be repaired. 22
to be drilled. Here, 23 is the edge of the sidewalk.

Next, after coating the pavement surface and the inside of the grooves 22 as necessary, the guide member 24 is planted in the grooves 22 and fixed at a predetermined level, as shown in FIG. 3(B). do.

After the guide member 24 is placed, a paving material 25 is poured between the guide member 24 and the end surface 23 of the sidewalk as shown in FIG. 3(C).

Next, while the paving material 25 is still uncured, the guide member 24 is moved while the leveling member 26 is vibrated, as shown in FIG. 3(D).
The surface of the paving material 25 can be smoothed and finished into a desired shape by moving it along the upper surface 27 of the paving material 25, for example in the direction of mark B in the figure.

Further, after the hardening of the paving material 25 is completed, as shown in FIG.
By drilling a hole 8, planting a guide member 29 therein, pouring the paving material 30 in the same manner as described above, and leveling the surface of the paving material 30 using the leveling member 31, it is possible to pave a wide area. Road surfaces can be easily paved continuously.

Furthermore, as shown in FIG. 5, by the method of the present invention,
A paved portion 31 is formed in a houndstooth pattern on a paving construction surface of a wide area, and then an unpaved portion 32 surrounded by the paved portion 31 is formed.
In addition, if paving is performed in the same manner as described above using the upper surface of the paved portion 31 as a guide member, it is advantageous because a large area of construction surface can be easily paved.

<Effects of the Invention> According to the coating method of the present invention, it is possible to reliably pave, finish, or repair damage on a paved surface with high workability.
The surface can be continuously finished into a desired shape, and the resulting paved surface is homogeneous. Furthermore, since work can be carried out continuously and quickly, it is also effective when using fast-curing paving materials. In particular, even if a paving material with high fluidity is used, it will not flow out to the outside, which is advantageous in terms of paving work.

Another advantage is that the thickness of the paving material can be adjusted during construction.
