However, the conventional permeable or drainage concrete block described above has a problem in that the amount of alkaline cement used is high, and thus it may contaminate the surrounding soil as well as groundwater for a long time, thereby causing environmental pollution.

In addition, the conventional water permeable or drainage concrete block described above uses a permeable material to allow rainwater to permeate, or a permeable passage is formed in the concrete block, but the permeable material and the permeable passage are weakened in durability and block even against a small impact. Since there was a disadvantage that could be damaged, there was a problem in that manpower consumption and maintenance cost for replacing or repairing the damaged block were incurred.

Rainwater that has fallen into each of the irregularities due to the formation of multiple drainage holes flows into the plurality of drainage holes along the "V"-shaped slope of the upper surface of each of the irregularities, and is among the rainwater that has passed through the plurality of drainage holes of each of the irregularities. Some of the voids between the plurality of filling seats are stored in a closed void, and the rest of the voids of the plurality of filling seats pass through the open void and the water permeable sheet to be discharged under the ground. Synthetic resin blocks are known.

In addition, the upper block 20 formed of a synthetic resin in Korea Patent Registration 10-1913602 (registration date October 25, 2018) and formed with a plurality of vertical permeable holes 21; An inner wall 33 formed of synthetic resin and forming an insertion groove 33a, and a stormwater discharge space 35 connected to the stormwater discharge induction space 32 outside the inner wall 33 and connected to the inner wall 33 Consisting of including an outer wall 34 to form and a grid-shaped support net 37 provided under the insertion groove 33a, and a support block 31 formed of an inorganic material inserted into the insertion groove 33a.

However, the block formed of the synthetic resin is assembled by stacking a synthetic resin cover and a synthetic resin rectangular body, and its manufacturing is complicated and expensive.In general, its thickness is too thick to be used for a sidewalk, so it can be used in the form of a concrete block. There was a problem that could not be.

A characteristic feature of the technology is that the surface of the organic-inorganic hybrid surface is formed with a non-slip part formed in a corrugated pattern, a comb pattern, or a grid pattern for preventing slipping when a vehicle or a pedestrian moves.

Hereinafter, embodiments of the present invention and/or drawings will be described in detail so that those of ordinary skill in the art can easily implement the present invention. However, the present invention may be implemented in various different forms, and is not limited to the embodiments and/or drawings described herein.

A drainage block having an acrylic resin and an organic-inorganic hybrid surface layer of the present invention and a drainage edge gap is described with reference to [Figs. 1] to [Fig. 6], including cement, crushed stone gravel, and a high-performance AE water reducing agent. A base layer portion 10 formed of a base layer mortar; An organic-inorganic hybrid surface layer portion 30 formed of an organic-inorganic hybrid surface mortar formed of an acrylic resin including cement, silica sand, scholestate and methyl methacrylate (MMA) resin located on the base layer portion 10; One or more drainage edge gaps 110 are formed at the edge of the configured concrete block 100 to facilitate drainage of rainwater to the lower soil through the drainage edge gap 110, and the organic-inorganic hybrid surface layer 30 It is configured to improve the surface strength and anti-slip performance.

At this time, the acrylic resin including the methyl methacrylate (MMA) resin should be mixed in 15 to 20% by weight of the total weight of the organic-inorganic hybrid surface mortar.

That is, the surface of the organic-inorganic hybrid surface has stability against a snow removal agent and surface finish, and in order to reduce shrinkage generated after drying, an acrylic resin containing methyl methacrylate (MMA) resin is mixed to provide surface strength and hardness. It improves, and accordingly, it is possible to provide high wear characteristics compared to the existing block.

When the acrylic resin containing the methyl methacrylate (MMA) resin exceeds 20% by weight of the total weight of the organic-inorganic hybrid surface mortar, the sliding resistance of the surface decreases due to the smooth coating surface, and when it is less than 15% by weight, There is a problem that abrasion performance is reduced

In addition, the particle size of the silica sand and the scolesite is preferable to use a particle size of silica sand 4 to 8.If the particle size is smaller than the particle size range, the slip resistance is also lowered, and if the particle size is large, the problem of particle separation and desorption There is this.

At this time, the scolesite is a tetrahedron of silicate and aluminate, such as natrolite, which is a hydrated sodium aluminum silicate mineral belonging to the zeolite group (the vertex of a triangle around a silicon or aluminum atom with four oxygen atoms in the center). It has a molecular structure composed of chains bonded to), and has a fibrous form because the horizontal bonds between the chains are relatively sloppy, so it improves the water permeability and makes the hydrate of the organic-inorganic hybrid surface mortar densely Therefore, it is used as an inorganic material of the present invention because it exhibits the effect of increasing long-term durability and resistance to damage such as freezing and thawing and salt damage.

In addition, the scolesite has a long and elongated prismatic crystal and fiber splint shape, so it has excellent sliding resistance performance, and shows colorless, white, transparent to translucent, glass gloss, and fibrous gloss, so it has very good visibility. There is an advantage.

In addition, the organic-inorganic hybrid surface mortar of the present invention may further include montmorillonite.

The Montmorillonite (hereinafter, MMT) is As clay, it is abundantly present in nature and is a very useful material in terms of economy, and gives excellent mechanical properties and chemical resistance.

In particular, in the MMT, platelets having a thickness of 1 to 3 nm form a layered structure with ionic binding force or van der Walls attraction, and the MMT having a layered structure serves as a reinforcing material of the polymer, so the mechanical strength of the polymer and, Since it has features of improving flame retardancy, abrasion resistance, heat resistance, etc., it is incorporated into the methyl methacrylate (MMA) resin of the organic-inorganic hybrid surface mortar of the present invention to impart excellent surface strength of the surface layer.

On the other hand, as shown in [Fig. 1] to [Fig. 2], the drainage edge gap 110 forms a semi-circular perforated portion at the edge of the concrete block 100 so as to match the semi-circular perforated portion of the edge portion of the adjacent concrete block. A circular perforated portion formed by open bonding is formed, and the radius of the semi-circular perforated portion is 2 to 3 mm, and it is butt-joined to form the circular perforated portion having a diameter of 4 to 6 mm.

As another example, as shown in [Fig. 3] to [Fig. 4], the drainage edge gap 110 forms a semi-circular protrusion at the edge of the concrete block 100 to form a semi-circular protrusion at the edge of the adjacent concrete block and It is also possible to form a uniformly formed gap gap by concentric bonding.

As another example, as shown in [FIG. 5] to [FIG. 6], the drainage edge gap 110 forms a bent portion in which a convex portion and a concave portion are continuously formed at the edge portion of the concrete block 100 to form an adjacent concrete. It is also possible to form a gap gap uniformly formed by combining with the bent portion of the block edge portion.

At this time, the drainage edge gap gap is preferably less than 7mm for the overlapping of the two blocks in consideration of joint construction, but if it exceeds 7mm, there is a problem that the walking weak and the women's shoe heels are caught.

In addition, as shown in [Fig. 7], the surface of the organic-inorganic hybrid surface portion 30 has a non-slip part 35 formed in a corrugated pattern, a comb pattern, or a grid pattern for preventing slipping when a vehicle or a pedestrian moves. It is preferably formed.
