Referring to these drawings, but mainly referring to FIGS. 1 to 3, the rainfall instant pitcher and storage pavement system of the present embodiment is connected to a lower layer L by a plurality of lower layer blocks 110 and a plurality of middle layer blocks 120. The intermediate layer M by the block 130 and the upper surface layer H by the plurality of

upper surface blocks

140a and 140b are manufactured.

First, the lower layer L may be formed by a plurality of lower layer blocks 110 in a state where the sand layer A is formed on the upper surface of the crushed aggregate layer B to level the surface.

As shown in FIGS. 1 to 6, the lower layer block 110 has

vertical coupling blades

111 and 112 formed on the side thereof to be coupled to each other in a vertical direction so that separation from the horizontal direction is prevented. It is a block structure in which one through hole 113 is formed.

In this case, the

vertical coupling blades

111 and 112 are formed on the first wing portion 111 formed on one side of the lower layer block 110 and the other side of the lower layer block 110, and are formed of the adjacent lower layer block 110. The first wing portion 111 includes a second wing portion 112 that is fitted in the vertical direction.

As shown in FIG. 4, for example, when the two lower layer blocks 110 are coupled to each other, the two lower layer blocks 110 coupled to each other are spaced apart in the horizontal direction by allowing the first and

second wing portions

111 and 112 to be coupled in the vertical direction. Since it is not separated, the strong binding force contributes to the stabilization of the road, that is, it can greatly strengthen the road compressive and shear resistance.

The first and

second wing parts

111 and 112 do not have the same shape, and a gap of 2 to 4 mm is formed therebetween, thereby maximizing the water draining effect.

As the first through hole 113 formed in a horizontal direction of the lower block 110 is formed to be somewhat larger in a large area in the center of the lower layer block 110, a large amount flowing through the upper surface layer H and the middle layer M is introduced. Rainwater can be stored immediately in the rain.

In the region of the first wing 111 of the lower block 110, a water drain groove 114 is further formed. The water drain groove 114 having a substantially hemispherical shape can effectively permeate and store water by maintaining an empty space even when the lower blocks 110 are laterally coupled.

The lower layer block 110 of the structure is formed such that its upper surface 110a is flat and the front surface 110b protrudes forward. This can be confirmed through FIG. 6.

Next, the intermediate layer (M) is formed as the area of the lower layer (L) in the horizontal direction on top of the lower layer (L), can be formed by a plurality of intermediate layer block 120 and also a plurality of connection blocks 130. have.

As shown in FIGS. 1 to 3 and 7, the intermediate layer blocks 120 form an intermediate layer M while being spaced apart from each other, and the intermediate layer blocks 120 spaced apart from each other are connected to each other by a connection block ( 130).

The connecting block 130 used in the present embodiment is applied to the cross-shaped connecting block 130 is disposed at a lower position than the upper surface of the interlayer block 120.

The intermediate layer block 120 has the same planar outer shape as the

upper surface blocks

140a and 140b. Thus, the interlayer block 120 may be prefabricated with each other while being fitted with the upper surface blocks 140a and 140b.

The intermediate layer block 120 is formed with a plurality of arc-shaped engaging arms 122 that are coupled in a vertical direction with neighboring upper surface blocks 140a and 140b to prevent separation in the horizontal direction. The arc-shaped engagement arms 122 arranged radially along the circumferential direction of the interlayer block 120 are connected to neighboring

upper blocks

140a and 140b while forming an approximately S-shaped ring. Due to this connection structure, the intermediate layer block 120 and the

upper surface block

140a and 140b are not spaced apart or separated in the horizontal direction, thereby contributing to the stabilization of the road with a strong binding force, that is, greatly improving the compression resistance and the shear resistance of the road. You can.

A second through hole 121 is formed in a vertical direction in the central region of the middle layer block 120. Since the second through hole 121 is formed to be large in the vertical direction, water draining and storage efficiency to this place are good.

Lastly, the upper surface layer H is formed on the upper portion of the intermediate layer M in the horizontal direction as much as the area of the intermediate layer M, and may be formed by a plurality of upper surface block blocks 140a and 140b.

As shown in FIGS. 1 to 3 and 8, the upper surface blocks 140a and 140b are disposed on the middle layer blocks 120 forming the middle layer M to form an upper side of the road pavement. It is connected to the middle layer block 120 in the horizontal direction.

Since the intermediate layer blocks 120 are connected by cross-shaped connecting blocks 130 having a height lower than the surface thereof, the top surface layer is kept horizontal after being disposed on top of the intermediate layer blocks 120 and the cross-shaped connecting blocks 130. To do so, the heights of the upper surface blocks 140a and 140b should be different as shown in FIGS. 8A and 8B.

In other words, in the present exemplary embodiment, the upper surface block blocks 140a and 140b are disposed on the first upper surface block 140a and the cross-shaped connecting block 130, which are disposed on the middle layer block 120, or mutually or mutually. It may be divided into a second upper surface block 140b connected to the first upper surface block 140a, wherein the thickness of the first upper surface block 140a is smaller than the thickness of the second upper surface block 140b. Can be. Thus, when the first and second upper surface blocks 140a and 140b are disposed on the middle layer blocks 120 and the cross connecting blocks 130, the upper surfaces of the first and second upper surface blocks 140a and 140b are disposed. Is horizontal.

As described above, the planar outer shape of the first and second upper surface blocks 140a and 140b and the intermediate layer block 120 are the same. As a result, the first and second upper surface blocks 140a and 140b are mutually assembled, and the first and second upper surface blocks 140a and 140b and the middle layer block 120 are fitted to each other. Can be connected. As the first and second upper surface blocks 140a and 140b are connected to each other, a gap G is formed between the first and second upper surface blocks 140a and 140b as shown in an enlarged portion of FIG. 3.

On the outer surfaces of the first and second upper surface blocks 140a and 140b, a plurality of arc-shaped

engagement arms

142a and 142b arranged radially along the circumferential direction are formed while forming an approximately S-shaped ring, and the neighboring ones are strongly bound. Thereby not being spaced apart or separated in the horizontal direction.

A rainfall immediate pitching and storage road pavement system for flood prevention having such a configuration will be briefly described with reference to FIG. 9.

First, a lower layer L is manufactured using a plurality of lower layer blocks 110 (S11). In this case, as described above, the lower layer blocks 110 are laterally connected by using the first and

second wings

111 and 112 so that the lower layer blocks 110 are not separated or separated in the lateral direction, that is, in the horizontal direction.

Next, the intermediate layer blocks 120 and the cross connection blocks 130 are assembled to form an equilateral triangle, and thus the intermediate layer M is manufactured by placing the intermediate layer blocks 120 and the cross-shaped connecting blocks 130 on the lower layer L (S12).

Then, the first and second upper surface blocks 140a and 140b are disposed on the middle layer blocks 120 and the cross-connected blocks 130, and then the first and second upper surface blocks 140a and 140b are disposed. By making the upper layer (H) while they are connected to the corresponding intermediate layer block 120 and the corresponding (S13), it is possible to complete the system of the form as shown in Figure 1, that is, the road pavement structure.

Having a connection structure of this type, even if an abnormality occurs in the ground due to the impact of the vehicle or other ground weakening, the arc-shaped

coupling arms

142a and 142b which are S-shaped rings cannot be separated or separated in the horizontal direction. Therefore, the compressive resistance and the shear resistance can be greatly enhanced.

In the case of the road pavement system having such a structure, the rainwater is permeated and dropped through the gap G formed between the first and second upper surface blocks 140a and 140b of the upper surface layer H, and then the intermediate layer ( The large space between the second through hole 121 and the cross-shaped connecting block 130 of M), and is stored in the first through hole 113 of the lower layer (L) and then penetrates into the ground. This can fundamentally solve the problems of flood damage and groundwater depletion, which can be caused by infiltration of rainwater.

As such, according to the present embodiment, the phenomenon in which separation or separation between the

blocks

110, 120, 140a, and 140b which are connected to each other can be effectively prevented, so that the flatness of the pavement surface can be kept constant, and above all, the rainfall immediately. Since the rainwater is permeated and stored at high speed, the outflow to the surface of the road is not generated, so it is possible to prepare for the damage of the flood at the source and to solve the groundwater exhaustion problem. In addition, since the

blocks

110, 120, 140a and 140b constituting each layer have a structure in which they are mutually bound in a ring form, not only are excellent interlocking in the horizontal and vertical directions, but also have excellent structural stability and durability. do. That is, even if the ground abnormality occurs, the blocks (110, 120, 140a, 140b) are not easily separated and separated, and even if the heavy vehicles pass frequently and the loads and impacts are repeatedly applied, they have excellent compression resistance and shear resistance and can be used semi-permanently. It becomes possible. In addition, by laying blocks in a multi-layer in order to increase the storage space, it is possible to be prepared even if unexpected rain falls suddenly.

In this case, the lower layer blocks 110 described above are stacked in a multi-stage direction in the height direction to complete the road pavement system. However, even when such a structure is applied, the present invention may provide an effect of the present invention.

As described above, the present invention is not limited to the described embodiments, and various modifications and changes can be made without departing from the spirit and scope of the present invention, which will be apparent to those skilled in the art. Therefore, such modifications or variations will have to be belong to the claims of the present invention.
