Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of constructing a suction file for constructing a suction file on the ground or at sea level,

The present invention relates to a structure of a hollow structure, an upper and lower slab covering an upper portion of the structure, and a suction file installed on an upper portion of the upper slab and configured to discharge air inside the structure to the outside, And more particularly, to a method of constructing a suction file for constructing a suction file.

In general, suction files and caissons are installed in the vicinity of a triangle of rivers or rivers to be used for industrial water, and are used to collect and supply groundwater (bridging water facilities, bridges, fresh water facilities, A power plant suction file facility, a breakwater cylindrical suction foundation facility, and the like).

The prior art of such a caisson or suction file is disclosed in Korean Patent Registration No. 1162152, which has a collecting space for storing a predetermined amount of water; An inserting portion which is vertically fitted to the lower portion of the collecting device so as to be in contact with the lower portion of the collecting device by a predetermined height and a blade portion which extends outwardly at right angles to the inserting portion; And an engaging means located inside the inserting portion of the fixture and having an upper end portion of a plurality of anchoring bolt portions vertically passing through the lower plate of the collecting box and positioned inside the collecting box. It is public.

Another prior art is disclosed in Patent Publication No. 1399090, in which a weight having a plurality of through holes formed to penetrate through the thickness thereof is placed on the upper surface of the seabed ground, A tubular member integrally provided with a stopper member having an upper end closed by the plate and protruding outwardly from the side surface is installed so as to be guided and guided by the through hole by passing through the through hole from the upper surface of the weight, The tubular member is penetrated into and fixed to the bottom of the seabed while the lower end of the tubular member is in contact with the surface of the seabed ground, the water in the hollow of the tubular member is drained through the drain pipe; The stopper member is provided with a vertical fitting member; A concave groove is formed in the upper surface of the weight body so that the vertical fitting member can be fitted therein; When the pipe member is inserted through the weight member and is fixed to the bottom of the seam, the vertical member is fitted in the concave groove; Since the stopper member protrudes outside the side surface of the pipe member, when the upward vertical load acts on the weight member while the pipe member is inserted into the weight member, the stopper member prevents the weight member from being pulled out of the pipe member, Wherein the suction member is configured to be transmitted to the pipe member through a stopper member.

However, there is a disadvantage in that the conventional suction file or method of construction or construction is not environmentally friendly. In the method of the existing patent publication, the water in the suction file is discharged from the drainage outlet Venturi, which is discharged to the side, has a disadvantage in that it can not function as water pressure.

Previously disclosed technology is that a sand boiling phenomenon occurs on the top of a pile of a suction pile inside a suction pile, so that the sand introduced into the top of the pile is accumulated and the pile is not completely pile up In addition, air and gas layers are generated and the structure is tilted or transmitted by the buoyancy force. As a result, the air and gas layers become larger as time passes by the naturally occurring gas and air in the sea floor and the residual oxygen in the water.

As the air and gas layers become larger, the buoyancy becomes larger. When the buoyancy is increased, the suction pile is less pressed on the bottom surface of the structure, and the suction pile structure is inclined or turned to an external shock due to the flow velocity, typhoon and tsunami.

It is an object of the present invention to provide an eco-friendly suction file construction method in which the construction of the suction pile is maintained so as to maintain the press-fitting and parallelism of the suction pile as the pressure of water.

It is another object of the present invention to provide an eco-friendly construction method in which a suction pile or various caissons are press-fitted as a water pressure so as to maintain parallelism and tightness. The present invention provides a method for minimizing the inclination or conduction of a suction file to an external impact caused by a flow velocity, a typhoon, or a tsunami.

A suction file comprising a structure in the form of a hollow body structure of the present invention, upper and lower slabs covering the upper portion of the structure, and an ejector installed on the upper portion of the upper slab to discharge the air inside the structure to the outside, The suction file construction method for installing the suction file is a step 1 in which the structure of the suction file is laid on the ground or the sea surface through the crane; A second step of fixing the structure placed on the ground surface or the sea surface by means of press-fitting air-tightness means; A third step of injecting high-pressure water into the inner side or outer side of the structure through the injection nozzle of the high-pressure pump when the structure is fixed by the press-fitting air-tightness means; And suctioning the sludge discharged by the high-pressure water injected through the injection nozzle through the suction nozzle of the suction unit and discharging the sludge to the outside. The installation device includes: a pressing means for pressing and fixing the suction pile structure seated on the sea surface by a crane; A high pressure pump in which an injection nozzle for injecting high pressure water is mounted on an inner bottom surface of the structure; And a sucking unit for sucking the sludge generated by the syringe nozzle through a suction nozzle and discharging the sludge to the outside.

As described above, according to the present invention, since water or soil, sand or the like used at the time of construction is discharged to the ground or sea and does not pollute and is used again, water is not wasted and the reused water is filtered by a water tank This is because the suction file and caisson are constructed by using water and it is very eco-friendly. Suction file and buoyancy is generated in the suction file by the air and gas layer in the lower layer of the slab of the caisson air- No suction file is inclined, no conduction occurs, and the conical shape of conical uneven ribs, which are air and gas outlets, blocks the gas, air and sand boiling shape of the press-in area, It acts as a barrier when wavelengths and impacts occur.

In addition, when the suction file and the caisson are inclined, and when moving or repairing, the concave conical key block cover can be lifted to press-fit, remove the sand, gravel, Air and gas coming out of the outflow pipe are leaked out to the ground ∩ El storage, and the air and gas pipes of the L storage are leaked out in the opposite direction, so that the suction file, caisson structure, press fitting, .
