The present invention is a construction cost by making it easy to pull out the round steel or H beam used to construct the earth wall to prevent ground collapse or leakage after the ground pitted in various construction and civil works The present invention relates to a film sheet for a pile construction file and to a construction method using the same, which saves and shortens the construction of the retaining wall while eliminating the risk of leakage.

It is common to use H-beams and circular steel or wood earthen boards for earthquakes in various constructions and civil works.However, when there are adjacent buildings such as urban areas, or the ground is weak, In order to prevent the backsoil loss due to piping and ground subsidence due to the decrease of the groundwater, the formation of the order wall is very important, and the aspect of the geology (soil layer and rock layer) must be taken into consideration. Various economical construction methods have been developed.

Such conventional soil barrier construction methods include H-pile and earth plate method, CIP method, SCW method, sheet pile method and underground wall (SLURRY WALL) method and the like.

First, the method using the H-pile and earth plate is installed in the ground to be installed with the earthen board with a boring device and then inserted into the ground or driven directly to the ground, and then proceed to dig the wood between the installed H-pile The earth plate is fitted to form a wall, that is, the soil barrier bar, because the soil barrier there is a lot of gaps to be ordered on the back of the soil barrier for additional order reinforced grouting.

When the earth plate is installed, a stable accident often occurs due to the fall of the earth plate. After the earth plate is installed, the backfill and compaction cannot be made. Therefore, if the deformation occurs due to the nature of the tree, the surrounding ground is displaced, which increases the earth pressure of the design by structural calculation. ,

The H-pile method has high soil plate stiffness, which is very likely to cause displacement of surrounding ground, and it is difficult to dismantle the earth plate when the service life of the facility is long.In this case, the soil is corroded in the soil, causing groundwater contamination and soil pollution and There is a problem of ground subsidence,

CIP (CAST-IN PLACE PILE) method is a kind of cast-in-place casting pile method that drills a hole with a predetermined diameter, inserts rebar or H-pile into the hole, fills gravel, and injects cement paste into the hole. As a method of forming the soil barrier, it is possible to construct the soil barrier between narrow and narrow sections, and it has the advantage that the rigidity is larger than the cross-sectional size.However, it is difficult to extract the H-pile, which increases the construction cost and makes it difficult to recycle the H-pile. There is this,

The SCW (SOIL CEMENT WALL) method is a casting method for casting heat in situ. The hole is drilled up to the planned depth by boring device, and the injection material is formed into the input wall and the H-pile is inserted into the stress agent to form the soil barrier. It is difficult to recycle piles, and the ratio of city factories is large, so that the work area should be large and the application length should be short, and it is uneconomical.

The present invention can increase the safety and save more than 65% compared to the construction cost of the conventional CIP method, and solve the problem of earth wall, in particular, it can be recycled without investing H-pile or circular steel, waste of resources It is to prevent.

As the present inventors for the construction sheet film sheet and the construction method using the same as the above to solve the above problems,

First, a film sheet is placed on the surface of the pile in order to make it easier to pull out a pile, which is a circular steel or an H beam, which is used to prevent soil and ground from collapsing when it is piled up to secure foundations and underground parts in construction or civil works. The purpose is to facilitate the separation of the pile by coupling and between the film sheet and the concrete retaining wall and between the pile through the hose,

Next, the H-beam or the circular steel can be taken out as described above, so that it is possible to recycle and to save the rebar and other concrete mortar, etc. without using wood that depends on imports, thereby saving resources and construction costs. For that purpose,

Next, it is possible to withdraw the H-beam or circular steel pile with a hydraulic jockey that can be moved by manpower, and the purpose is to enable cost savings by drawing out by mobilizing large equipment,

The film sheet used in the present invention can be made to reduce the construction cost by manufacturing paper cardboard, vinyl, fiber fabric, sand, earth and sand, sawdust, tube to be recycled is an object of the present invention.

Specific solutions for achieving the above object are the steps of forming a first adhesive layer by spraying or applying an adhesive primer on a fabric made of a fiber material, and then bonding the plastic sheet to the first adhesive layer and then again the adhesive primer Spraying or applying to form a second adhesive layer, adhering a plurality of perforated paper cardboard to the second adhesive layer, and inserting or spraying sand, soil, sawdust, etc. into the plurality of through holes. And spraying or applying an adhesive primer to form a third adhesive layer, and fixing and bonding a hose having a plurality of holes perforated to the third adhesive layer, and then spraying or applying an adhesive primer to form a fourth adhesive layer.

And cutting and bending the c-beams surrounding the coating sheet and the pile at both ends to integrate the pile and the coating sheet, and the pile sheet coupled to the perforation hole in the state in which the coating sheet and the pile are integrated. The step of entering and joining the spring-shaped wire mesh reinforcing bar on its outer circumferential surface while being spaced apart from the pile in which the indented film sheet is coupled, and placing concrete between the piles in which the perforated hole and the film sheet are combined. And injecting water into the hose in the process of curing the concrete so as to separate the pile from the coating sheet, and then extracting the pile, and injecting concrete milk into the hose after extracting the pile.
