Description

Technical Field [0001] The present invention relates to a method of constructing a complex river system using connecting means between walls,

The present invention relates to a composite type bridging facility method using a brick layer connecting means between walls, and more particularly, to a brush type brick building method in which a brick layer installed in a brick construction method using a brick wall is used for hitching and pulling It is possible to install and dismantle the water to the underwater or to the purchase site of the earthworks and thus it is possible to reduce the process time, the construction cost can be reduced, the possibility of safety accident can be reduced, and the mutual bearing capacity of the wall can be improved The present invention relates to a method of constructing a complex river system which is easy to disassemble.

Generally, a shroud is a facility temporarily installed to prevent water from flowing underwater, and it is usually constructed by using a caisson or hitting a sheet pile.

The existing shale film construction method is mainly used to install a floating shale film for a river, lake, and sea using a pile (sheet file), install separate bridge or livestock road, or take a separate work barge Build facilities.

In the case of a single sheet pile installed in one row as in Korean Patent Application No. 10-2010-0136005, the strength of the wall is poor due to the characteristics of the steel, It is easy to cause wall deformation by side pressure, and it is necessary to use the supporting method separately by using the supporting material. Since the piping phenomenon due to the piping phenomenon due to hydraulic pressure causes the uncertainty of the order, This is a major cause of the excessive construction period and construction cost increase.

Therefore, in a region with a large water pressure, a two-row sheet pile wall is used. In the case of a two-row parabolic sheet wall, the sheet pile is inserted into two rows of sheet piles. The sand is used as a filler material. In order to prevent the occurrence of the widening of the walls due to the load of the gypsum when the internal high-quality tapping is carried out, tie cables are bound at left and right A technique for preventing the deformation and spreading of the sheet file wall is mainly used.

However, in the conventional tie cable method, since most of the walls of the shroud are installed at a certain interval in water or in the ground, in the case of underwater, underwater work using a diver should be carried out. In reality, There are various problems.

In addition, when the opposite tie-sheet file walls are mutually pulled together using existing tie-cables, it is necessary to secure a construction tension hole, so drilling work of the sheet file is inevitable and material damage occurs. Therefore, a separate large barge and expensive underwater equipment are required, and there is a problem that the air is lengthened and the possibility of a safety accident increases. Also, there is a problem that underwater work involving a diver must be performed at the time of disassembly work of the sheet file. Also, tie cables can not be installed in the ground.

In recent years, there has been used a method of welding an angle or a steel bar to an upper portion of a facing sheet file, but this is because only the upper portion of the sheet file can be welded and the underwater portion can not be welded. There is a problem that a gap is generated.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems occurring in the prior art, and it is an object of the present invention to provide a method, The present invention is to provide a composite riverbed construction method which can reduce time, reduce construction cost, reduce the possibility of occurrence of safety accidents, improve the mutual bearing capacity of walls, and facilitate dismantling work.
