The low water permeability block 100 of the present invention is filled with a low water permeable material 20 therein and has sufficient bending strength and compressive strength against alternating load and static load of a vehicle running on its own to prevent breakage or deformation. It is a structure.

In addition, the present invention can reduce the installation thickness of the pavement layer 400 to be described later through the low water permeability block 100 having bending strength and compressive strength structure that can achieve the desired purpose of reducing the construction cost Is prepared.

The low water permeability block 100 is a block 10 in which the protruding ports 11 are arranged to be spaced apart at regular intervals in the horizontal and vertical directions, and a low water permeable material filled in the lower surface of the block 10. 20).

The block 10 has a lattice structure through a partition plate 12 connecting the protruding port 11 and the protruding port 11 adjacent thereto to form the reservoir space 13.

In addition, the block 10 further comprises a contact end portion 14 extending upward and downward at the edge. The upwardly extending portion of the contact end 14 functions to store rainwater on the reservoir space portion 13, and the downwardly extending portion is used to fill the entire thickness of the low water permeability material 20 filled. Determining

 In addition, as shown in FIG. 3, the four protrusions 141 and the fitting groove 142 may be formed on the four sides of the contact end portion 14 so as to be mutually coupled with the contact end portion 14 of the adjacent block. .

Here, the opposite surface of the portion where the fitting groove 142 is formed is relatively protruded, and thus the coupling force of the low water permeable material 20 filled by the fitting groove 142 may be further increased.

On the other hand, the bottom portion of each of the reservoir space portion 13 partitioned through the partition plate 12 has a structure that is further formed with a second inlet hole 131 through which rain water can be introduced.

The storage space 13 has a shape in which the ground clearance is lowered toward the center so as to guide rainwater to the second inflow hole 131. At this time, the second inflow hole 131 is a structure forming a community so that rain water flows into the low water permeability permeable material 20.

The protruding port 11 of the block 10 has a conical shape in which the diameter thereof becomes smaller as it goes upward.

At this time, the upper part of the protruding port 11 has a flat surface to form a flat surface, and the first inlet hole 111 for introducing rainwater forms a colony on the upper surface.

In addition, the outer circumferential surface of the protruding port 11 is formed with a spiral rainwater induction jaw 112 to induce rainwater, the rainwater induction jaw 112 is a structure in which a plurality of third inlet hole 113 is further formed. to be.

Such a structure is such that when the rainwater penetrated from the upper side comes into contact with the outer circumferential surface of the protruding port 11, the rainwater guided jaw 112 is led to the third inflow hole 113 so that the rainwater may flow into the low water permeable material 20. It is a structure.

As such, the rainwater flowing into the first inlet hole 111, the second inlet hole 131, and the third inlet hole 113 formed in the block 10 is stored, and the rainwater is continuously pumped for a predetermined time to determine the amount of rainwater. The low water permeable material 20 serves to reduce the pressure and to serve as a series of aggregate layers.

The low water permeable material 20 is a structure filled in the lower surface of the block 10. At this time, the inner circumferential surface of the protruding port 11 is formed with a plurality of engaging projections 114 to prevent the separation of the low water permeable material 20 filled with the fitting groove 142 of the contact end 14. It is a structure that can be done.

Prior to the detailed description of the low water permeable water permeable material 20, the most ideal water permeable material in the present invention is to improve the compressive strength by lowering the permeability coefficient to improve the water storage capacity and to reduce the particle size distribution of the aggregate.

 The low water permeability permeable material 20 is preferably composed of a mixture of 93 to 98% by weight aggregate having a particle size distribution of 3mm ~ 20mm, and a binder of 2 to 7% by weight mixed with a curing agent.

It is preferable that it is comprised by mixing 97 weight% and 3 to 7 weight% of a binder which the hardening | curing agent mixed.

The low water permeability reduction material 20 has a structure in which the particle size distribution is reduced to lower the permeability coefficient, thereby improving the water storage capacity, further reducing the post-storage reduction function, and improving the compressive strength by increasing the content ratio of aggregate.

When the particle size distribution of the aggregate is 3mm or less in the above, the density of the aggregate is increased and the water storage amount is not preferable, and when it is 20mm or more, the water permeability is increased and the water storage capacity is not preferable.

In addition, when the weight% of the aggregate is 93 or less, the amount of expensive binder is increased and economic benefits cannot be expected. In the case of the weight% 98 of the aggregate, the binding strength of the aggregate due to the insufficient content of the binder is reduced, resulting in low water permeability in the block. It is not preferable because ash is likely to escape.

In addition, the aggregate is preferably composed of any one of recycled aggregate or crushed stone.

The binder is preferably any one selected from unsaturated polyester resins, urethane resins, and epoxy resins, and more preferably unsaturated polyester resins having excellent binding strength of gravel.
