Description

Support block for ground hole < RTI ID = 0.0 >

The present invention relates to a ground aperture support block.

Background Art [0002] Conventionally, in ground openings of underground constructions such as a manhole for inspection of sewerage installed on a sidewalk, a hydrantshed room installed in a waterway, a wastewater chamber, etc., or an underground room installed at a branch point of an electric or communication cable buried in the ground , A disk-shaped cover plate of the cast iron and its seat frame are provided so that the surface of the cover plate coincides with the ground surface.

However, the sidewalk is packed in blocks so that vehicles, people, etc. can walk easily.

Therefore, the top of the ground opening is positioned higher than the natural ground surface in consideration of the fact that the block to be the artificial ground surface is wrapped around.

Nowadays, in order to realize various patterns on the packing surface of the block packed on the natural surface around the above-mentioned ground opening, the blocks having the rectangular cross-section are packed on the natural ground surface, And the material of the cover plate can be matched with the block of the packaging surface. In addition, in order to withstand the load, the cover plate is made of a synthetic resin and a binder , Glass fibers, dolomite, and a hardener are mixed and compression-molded.

Such a cover plate is disclosed in Korean Patent Registration No. 10-1388244, which is a patent application and patent registered by the present inventor.

In addition, in the above-mentioned publication, the above-mentioned ground openings and the cover plate are disc-shaped, and the blocks are formed in a rectangular parallelepiped so as to represent rectangular patterns on an artificial surface to be packed in a block around the outside of the ground opening, It is necessary to perform a cumbersome paving operation for cutting the portions of the blocks which are brought into direct contact with the outer circumferential surface into an arcuate shape. In order to exclude this, it is necessary to directly connect to the sides of the blocks of the artificial surface surface in conjunction with the pattern engraved on the surface of the cover plate Discloses a ground-opening support block in which a through-hole is formed so that it can be packed on a natural ground surface without cutting the block, and is circumscribed at the ground-level opening at the center, and the outline of the frame is rectangular.

As in the case of the cover plate, the ground-opening supporting block has a pattern engraved on its surface so as to match the pattern of the packed surface, and the material of the ground- In order to withstand the load, a mixture of synthetic resin and binder glass fiber 촙, dolomite, and hardener is pressed and molded in the state of reinforced cement or reinforced concrete planted.

However, in the above ground-opening supporting block, the center of the upper side, the lower side, the left side and the right side is significantly narrower than the other portions. When the ground-opening supporting block is placed on the supporting wall in an inclined posture, There is a problem in that deformation or cracks easily occur even when the steel plate is deformed or cracked to cause disassembly at the time of transportation or storage and cost of material due to the reinforced steel rod is increased, and the steel plate has a size larger than the size of the lid plate, There is a problem that the manufacturing cost of the biaxial extrusion molding is increased.

The present invention has a problem in solving the above-mentioned problems.

The present invention relates to a method for producing a reinforced concrete structure, which comprises compression molding a mixture of a cementitious material, a synthetic resin, and a binder, glass fiber reinforced plastics, dolomite, and a curing agent, The above problems can be solved by molding the flake-shaped portions into a piece-like portion and wrapping the flake-like portions on a natural surface around the outer peripheral surface of the ground opening.

According to the present invention, the block is packed on the natural ground surface in the vicinity of the ground opening, and the block is matched to the pattern and the material of the cover plate of the wrapped artificial earth surface, It is possible to provide a ground aperture support block which is excluded so as to reduce the material cost, reduce the size of the mold, reduce the molding production cost, and prevent deformation or cracking easily.
