Deformed cladding materials for extracting pile temporary bracing work using the same}
[19] The present invention relates to the earth wall method used in the temporary earthquake method, in particular in the downtown close-up construction, and more particularly, by allowing the file to be inserted and cured in the concrete earth wall to be removed and reused using a separate release coating material, It is a release coating material for pile extraction and temporary soil wall construction using the same, which reduces construction costs and prevents soil contamination due to expensive pile reuse, and overcomes obstacles of excavation during redevelopment.
[20] In the case of ground excavation for the construction of a structure (civil engineering / building site), temporary wall construction is carried out as a general method to maintain stability of adjacent major ground surface by preventing soil collapse and suppressing displacement of excavation backing.
[21] In particular, the recent frequent construction of urban centers has resulted in the demand for settlement of adjacent ground due to ground excavation and the stability of surrounding buildings. Therefore, the importance of temporary wall construction is increasing.
[22] The hypothesis earthquake method is classified into the earth wall method and the earth wall support method. Among them, the earth wall method installed in the city center prevents ground collapse and lowers the groundwater level due to the excavation backing, and prevents the outflow of soils. It should be a method that can minimize the sinking of
[23] The temporary soil wall construction method used in the city center is mainly used for continuous wall construction methods such as soil cement wall construction (SCW) and cast-in-place concrete pile construction (CIP). LW grouting , SGR grouting, JSP method are used for order and ground reinforcement.
[24] In addition, the earth wall method described above is used for the purpose of increasing the rigidity of the earth wall by inserting a pile (H-pile) in the continuous wall.
[25] However, the file used in the earth wall method as described above is that the concrete is being cured and inserted into the earth wall at the same time, there is a problem that expensive files are unnecessarily dead, this residual file is a waste of unnecessary resources In addition, after a certain period of time, the soil pollution is aggravated by causes such as corrosion.
[26] In addition, in addition to the excavation failure by the file during the excavation work due to the subsequent reconstruction, the file obtained by the excavation is not possible to reuse, there is a serious problem that adds to the double environmental pollution classified as industrial waste.
[27] The present invention has been made to eliminate the problems described above, by using a release coating layer made of polymer or bentonite embedded in a double non-woven fabric layer of the inside and outside when inserting the release coating material together in the pile in the earth wall, moisture in the concrete curing process By absorbing the withdrawal of the pile by the release coating material changed into a gel state, by pouring cement milk grouting in the withdrawal pile insertion hole to secondary curing,
[28] The stiffness of the earth wall is maintained, and the expensive files are taken out and reused, thereby reducing construction costs and minimizing environmental pollution due to the piles of metals. Also, no files are discarded without any excavation obstacles caused by reconstruction. It is an object of the present invention to provide a release coating material for pulling out files having an environmentally friendly effect, and a temporary soil wall construction method using the same.

As configured by
[33] It is preferable that the absorbent release layer 3 is filled with a super absorbent polymer, bentonite, or the like.

[44] It will be a curing process for curing cement milk grouting.
[45] In the drawings, reference numeral 10 denotes a file, 11 an earth wall, and 12 a ground.
[46] If described in more detail by the accompanying drawings, the process according to the release coating material and the construction method using the same as described above are as follows.
[47] Fig. 4A is a perspective view of a pile 10 inserted into a release coating material 4 composed of internal and external nonwoven fabric layers 1 and 2 and an absorbent release layer 3 formed in a spaced portion thereof. The release coating material 4 is formed to a size such that the pile 10 is sufficiently wrapped in the coating material 4, and the pile 10 is inserted therein.
[48] Such a cover pile is inserted into the perforation of the ground 12 excavated by a pile driver (not shown in the figure) as shown in FIG. 4B, as shown in FIG. 4C,
[49] When the covering pile is completely inserted into the drilling hole, concrete is placed in the space between the covering pile and the drilling hole as shown in FIG. 4D.
[50] The concrete poured in this way is sufficiently pressed against the outer circumferential surface of the pile (10) wrapped in the bag and is cured evenly over the entire area except the volume of the pile (10) and the release coating (4).
[51] In addition, since the concrete contains a certain amount of moisture, the release coating material 4 absorbs the moisture contained in the concrete at the same time as the curing of the concrete in the curing process of FIG. 4E to which the superabsorbent polymer or bentonite is filled. The absorbent release layer 3 is changed in shape into a gel by moisture, and at the same time, the absorbent release material 3 has an expansion force of two to three times its initial thickness.
[52] When the earth wall in the state in which the pile 10 is inserted is completed, the foundation floor and the structure are constructed on the excavated and excavated ground of the destination board, as in the known structure construction method as shown in FIG. 4F. And it is to remove the pile 10 inside the earth wall in a state in which the structure is completely constructed.
[53] Therefore, as shown in FIG. 4G, the pile 10 inserted by the gel-absorbent release layer is easily taken out by using a separate pile driver or the like. The gel 10 is formed between the pile 10 and the concrete curing section. Since the absorbent release layer 3 is spaced apart, the pile 10 is easily drawn out by the elastic absorbent release layer 3.
[54] After the pile 10 is drawn out in this way, cement milk grouting may be poured into the pile insertion hole as shown in FIG. 4H.
[55] By performing each of these processes, a solid earth wall 11 as shown in FIG. 4I can be obtained.
[56] The earth wall 11 is to prevent the displacement of the ground 12 and to prevent the collapse of the soil, as well as to effectively maintain the stability of the adjacent peripheral ground as in the prior art.
[57] In addition, since expensive piles can be taken out and reused, the construction cost can be reduced and the resources can be greatly recycled. Soil contamination due to metal pile corrosion can be prevented, Since there is no excavation obstacle at all, it can be called a more efficient construction method.
[58] In the present invention, the release coating material for file extraction and the temporary earthquake earth wall method using the same, while maintaining the rigidity of the earth wall, withdraws and reuses expensive piles, thereby reducing construction costs and minimizing environmental pollution due to metal piles. In addition, since there are no excavation obstacles occurring at the time of reconstruction, the discarded files do not occur, so there is a more environmentally friendly effect.
