Description

Interlocking Multi-Function Block}

The present invention relates to a block for civil engineering, more specifically, it is easy to construct by constructing in a prefabricated form, buoyancy collection hole and dispersion passage to form a buoyancy quickly removes buoyancy when installed in water to improve the workability, adjacent By forming a space in the area where the blocks meet to increase the bond strength by using a U-bolt to increase the bond strength, and provides a double triple fixed coupling structure in the vertical and horizontal directions, excellent coupling force between the blocks, by providing a variety of members The present invention relates to a multifunctional block for civil engineering, which is excellent in field adaptability and can be applied to a construction site.

In general, basic construction is very important for various civil works. For example, at the base of the piers, vortices occur around the circular piers due to the flow of water and are scoured. An example of this catastrophic disaster is the collapse of the Seongsu Bridge (October 21, 1994) and the recent collapse of the Gaoping Bridge in Taiwan (August 27, 2000). Therefore, the so-called scour prevention work, which is constructed by stacking a plurality of blocks, is carried out at the foundation part of the pier.

In addition, rivers will be provided with freefalls and retreats for the purpose of reducing the flow rate and protecting fish. The drop-off ball may be a natural stone-shaped revetment block, an eoso block, a shoalable grain (possible to use a bridge), or an esophagus block to keep fish well. In addition, there is a floor compaction work to be installed on the floor of various dams and blowholes.

By installing such a drop or bottom compaction in the river, free passage of fish in the up and down stream, purification of natural water quality due to aeration, and an environment in which willows, reeds, plants, etc. can grow, provide a habitat for fish habitats. As a result, it gains a great effect in restoring natural ecosystems.

These projects are inevitably constructed using unit chain blocks consisting of 2, 4, 6, etc. In order to prevent scrubbing of foundations and loss of soil due to the flow velocity, these blocks cover the foundations of the structure or cover the gabions after filling them, and use concrete placing and ready-made products according to the purpose. Doing.

In addition, the block is used for a variety of uses, such as water intake bureau protection, river bed exposed pipeline protection, soft ground flow path stabilizer, eyepiece stabilizer (block retaining wall construction), emergency flood recovery.

Conventionally, a block for protecting the foundation of an underwater structure is formed by symmetrically forming recesses and convex portions diagonally on the upper and lower surfaces of a square block body (Domestic Utility Model No. 78-1501). Laid At this time, the block and the block is simply a surface contact only on the side, and the blocks stacked thereon are stacked so as to occlude up and down.

However, such block masonry is the part that should be the basis, that is, the blocks and blocks that are laid out on the surface of the water are not bound to each other, but simply face-to-face. The block structure collapses and eventually the foundation of the underwater structure cannot be protected.

As another example, each of the upper and lower surfaces of the block body has recesses and protrusions, and a plurality of protrusions of the same height at the top and bottom at regular intervals are provided, and a fastening groove for fastening is provided at the center and the circumference. 57-174526 (Public Utility Model Publication No. 57-174526) during construction, it is to be stacked in a line with a steel wire to form a single columnar mass, and to be stacked around the foundation.

Such a block in the state of agglomeration does not effectively cover the underwater indicators of the foundation of the underwater structure, because the space between the block and agglomeration is large, there is a problem that can not prevent the crushing phenomenon in the river with a high flow rate.

In order to solve this problem, Korean Patent No. 10-0224526 (registered on July 14, 1999, application number 10-1997-0017176) has several upper and lower vertical protrusions protruding from one another on upper and lower surfaces of a unit member formed of concrete. Upper and lower vertical coupling grooves formed between the coupling protrusions and the upper and lower vertical coupling protrusions to allow gearing of the upper and lower vertical coupling protrusions, and protrude at both ends of each of the left and right side surfaces of the unit member. Left and right horizontal coupling protrusions for allowing adjacent unit members to be engaged with each other, and left and right horizontal coupling portions for receiving horizontally and horizontally forming unit members in the middle portions of the left and right sides of the unit member to horizontally couple the unit members. Concrete blocks for the foundation protection of underwater structures consisting of joining recesses are known.

In addition, Patent No. 10-0253849 (Registration Date: January 27, 2000, Application No. 10-1998-1620) is provided with a projection and groove in the upper and lower, buoyancy bubbling hole penetrated up and down in the groove and is reinforced on all sides The structure consists of a mat on which the shackle-filled part flows while having a width and weight designed by filling the reinforcing bar connections in the assembly intervals with the spacing between the side surfaces of the unit members provided with the connection planes in a planar manner. Block mats for the reinforcement of foundations are also known.

However, the conventional blocks are lighter than the volume of the reinforcement stone and gabion reinforced to the foundation portion of the structure is often crushed by the flow rate due to the flow rate during floods or heavy rains, the structure is often collapsed, roads, railways, embankments, rivers, etc. Catastrophic damage to facilities has resulted in repeated material damage every year.

The revetment of coastal facilities is a block composed of a plurality of protrusions, which is heavy in weight, poor in portability, and poor in workability. Loss of sandstone and scour phenomena is unsuitable for permanent structures.

The coastal, river, and bridge construction is mostly underwater construction, and it is difficult to install because it is difficult to lay the concrete when reinforcing the foundation foundation and installing the revetment. Therefore, the construction is difficult, the air is late, and huge construction cost is required.

The present invention is designed to solve this problem in consideration of the above-mentioned conventional problems, it is easy to construct by constructing a prefabricated and to form a buoyancy collection hole and dispersion passage to quickly remove the buoyancy when installed in water to improve the workability, By forming a space in the area where the adjacent blocks meet to be locked by using a U-bolt to increase the bond strength of the key, and provides a double triple fixed coupling structure in the vertical and horizontal directions to provide excellent bond strength between the blocks, The purpose is to provide a multifunctional block for civil engineering that can be applied and applied to the site where it is excellent in adaptability to the site. The civil engineering block is called IL (Inter Locking) block in other terms.
