The present invention relates to a method for constructing a prefabricated fish and its components, and more particularly, to a method of constructing a prefabricated fish that installs the interlaced wall and the overflow wall on the bottom plate after the first construction of the bottom plate of the fish.

Structures installed across rivers can hinder the movement of anadromous creatures such as sweetfish, eel, and crabs and local aquatic organisms such as fish, crustaceans, and amphibians. In order to prevent ecological migration and habitat disturbance caused by this, and to protect various river ecosystems, fisheries are installed.

Conventionally developed utility model registration No. 20-0236323, front and rear legs, which are rectangular concrete structures, are formed, and the front and rear legs are fitted to each other in front and rear, and are joined together. Disclosed is an airway block in which a recessed jaw and a rear projecting jaw are formed.

The airway block is formed in the side passage connecting loops to be fixed to each other neighboring fishery block with a coupling mechanism, etc., and the overflow portion of the overflow freshwater overflows to the front of the freefall freshwater is formed The water overflowing the free fall freshwater portion of the adobe block, which is installed at the rear of the water drop, falls down to the free fall freshwater portion at the front, and is configured to flow down naturally to the lower free flow block.

However, the conventional fish block is a vulnerable problem that the inclination of the fish exceeds the river design standards, the flow rate is fast, difficult to use a variety of fish, such as small or young fish, and the downstream of the fish is severely scoured, making it difficult to burn the fish and damage the structure Has

In particular, such fish have a serious problem that the fish do not flow because the water does not flow accurately or does not consider the change in the flow rate and the water level of the river or the water flows quickly to overflow the side wall of the fish. In addition, the concrete strength of the constructed fish can fall below the standard value, causing a structural problem in which the bulkhead of the fish can be damaged due to the torrent during flooding, or the stone can be introduced into the fish and deposited and scoured downstream.

As an advanced technology for this, the prefabricated fish and its construction method according to Patent No. 478900 (05.03.16), to which the applicant has been registered, reduce the inclination of the fish and reduce the influence of flow velocity and turbulence, The flow wall of the middle row and the right row are different from each other, so that it is excellent in responding to the change of water level, and the construction of the site is more robust, and thus the river applicability is high. However, since the overflow block and the non-flow block are composed of the bottom plate and the wall surface integrally, the overflow block and the non-flow block have a problem that the transportation method is difficult due to the heavy and bulky dullness.

The present invention has been devised to solve the above problems, and an object of the present invention is to provide a method of construction and assembly of a prefabricated fish construction that is simple in construction and structurally robust.

The object of the present invention as described above, in the method of constructing a prefabricated fish by alternately installing the intersecting portion (1) and the overflow portion (2), the interlacing bottom plate 100 and the overflow bottom plate (base floor plate) ( Constructing the bottom plate of the esophagus by integrally extending 200) front, rear, left and right; And installing the interlacing wall 10 at the upper portion of the interlacing bottom plate 100 and installing the interlacing wall 20 at the upper portion of the interlacing bottom plate 200 (in case of installing concrete); It is achieved by a construction method of prefabricated fish characterized in that it comprises a.

In the present invention, since the construction of the overflow wall and the non-flow wall separately in the production site for the efficiency of the construction method is configured to carry and assemble it to the construction site has an excellent feature in the construction method.

Other objects, specific advantages, and novel features of the present invention will become more apparent from the following detailed description of the invention and the preferred embodiments in connection with the accompanying drawings.

Hereinafter will be described the configuration of the construction method of the prefabricated fisheye according to the present invention.
