2, the protection material P is a waterproof layer protection material that covers and protects the waterproof layer W applied to the outer wall surface C of the underground structure. The protection layer P includes a first protection layer 1, 2, and an adhesive layer 3, and may further include a release paper 4.

As shown in FIG. 3, the first protective layer is formed of a hard type. Here, the hard type is referred to as a second protective layer, It means that the rigidity is excellent, and it is not a concept to be expressed by an accurate numerical value.

In one embodiment, the first protective layer 1 may be formed of a polypropylene (PP) board in order to secure proper rigidity. In addition to securing rigidity, it can improve buffering and insulation, A buffer hole 10 may be provided in the inside of the chamber. 3, a plurality of buffer holes 10 may be provided over the entire first protective layer 1, and the buffer holes 10 may be formed to have a size that does not impair the rigidity of the first protective layer 1.

Further, the friction reducing means may be provided on the outer surface of the first protective layer 1, and the friction reducing means can prevent the waterproof layer (W) from sagging due to the earth pressure, prevent consolidation settlement, Thereby improving the resistance of the battery. Such friction reducing means can be realized by smoothly treating the surface of the first protective layer 1, and further can include application of a lubricant, attachment of a friction reducing sheet, and the like.

Next, as shown in FIG. 3, the second protective layer 2 is of a foam type and is bonded to one side of the first protective layer 1, (2) has a soft property relatively to the first protective layer (1) because it is made of a foam type. In the above expression, one side of the first protective layer 1 refers to the inner side, that is, the side of the waterproof layer W, based on the construction state.

In one embodiment, the second passivation layer 2 may be made of a polyethylene (PE) foam having a void 20 therein, and the inner void 20, in particular as a foam, , Impact absorption performance improvement, and the like.

Next, as shown in Fig. 3, the adhesive layer 3 is bonded to one side of the second protective layer 2 and adhered to the waterproof layer W, and should include self-adhesive or coated adhesive Here too, the term 'one side' refers to the inside on the basis of the construction state, and more specifically to the side of the waterproof layer (W).

3, the releasing paper 4 is configured to conceal the adhesive layer 3 and the adhesive layer 3 can be exposed through the removal of the releasing paper 4, Concrete implementation can refer to conventional techniques.

4, the protective material P includes bonding means 5 for bonding the first protective layer 1 and the second protective layer 2 to each other, And the like.

The joining means 5 improves the bonding force between the first protective layer 1 and the second protective layer 2 to improve the durability against the earth pressure.

More specifically, as shown in Fig. 4, the bonding means 5 is provided with a bonding hole 51 formed in the first protective layer 1 by a laser or a corona discharge or both, and a first protective layer 1, And an adhesive (52) interposed in the second protective layer (2) and penetrating into the joint hole (51).

Because of this feature, the protective material P is bonded to the first protective layer 1 and the second protective layer 2 by bonding the adhesive 52 to the bonding hole 51, So that the bonding between the first protective layer 1 and the second protective layer 2 becomes firm and the durability against the earth pressure is improved.

Next, in the protective layer joining step S2, the adhesive 52 is interposed in the first protective layer 1 and the second protective layer 2 so as to allow the adhesive 52 to permeate the joint hole 51, The layer 1 and the second protective layer 2 are bonded together.

Next, the adhesive layer bonding step S3 is a step S3 in which the adhesive layer 3 is bonded to one side of the second protective layer 2.

The effects of the above steps are the same as those described in the description of the present protective material, so that redundant description will be omitted.

Meanwhile, in one embodiment of the present invention, the protective material further includes a waterproof reinforcing layer provided on the other side of the first protective layer, between the second protective layer and the adhesive layer, or both, so as to further improve waterproofness . Accordingly, the present manufacturing method can further include the step S4 of providing a waterproof reinforcing layer.

More specifically, the waterproof reinforcing layer may include 2 to 3% by weight of pozzolan, 3 to 4% by weight of wax or paraffin, 1 to 2% by weight of styrene thermoplastic elastomer, 2.5 to 3.5% by weight of a hardening agent, 1.5 to 3% by weight of an amorphous polyolefin (APO) and 0.5 to 0.7% by weight of an iron slag.

Pozzolan is a natural mineral material such as Diatomite, which provides purification of foreign matter adhering to the outer surface of the waterproofing layer by anion release, deodorization and antibacterial action. And prevents the occurrence of cracks in the waterproof strengthening layer. When the pozzolan is less than 2% by weight, the cleaning effect is low, and when it is more than 3% by weight, the binding force is decreased.

Next, the waterproof reinforcing layer may contain 3 to 4 wt% of wax or paraffin. Since the wax or paraffin has a melting point of 40 to 60 DEG C, it functions to lower the production temperature of the waterproof layer, The waterproof reinforcing layer is melted and hardened and then volatilized, thereby not deteriorating the quality. When the wax or paraffin is added in an amount of less than 3% by weight, the effect of addition is scarcely added. If the wax or paraffin is added in an amount of more than 4% by weight, the brittleness of the waterproof strengthening layer increases and cracks are easily generated.

Next, the waterproof reinforcing layer may contain 1 to 2% by weight of a styrene thermoplastic elastomer. The styrene thermoplastic elastomer has a polystyrene block as a hard segment in a short-term end and a soft segment as a poly- It has a soft segment structure and can be made low viscosity when dissolved in mixed solvent. It has high elasticity and low temperature durability, so that cracking of the waterproof strengthening layer caused by the elapse of time and lack of low temperature durability during the winter season, The synthetic zeolite powder dispersed in the particulate state has an advantage that the waterproof layer can have a certain buffer against the external force due to regular fine pores inside.

If the content of the amine-based curing agent is less than 2.5% by weight, the strength and durability of the waterproof reinforcing layer may deteriorate to deteriorate physical properties. If the content of the amine-based curing agent exceeds 3.5% by weight The viscosity is increased and the workability is lowered.

The amorphous polyolefin (APO) is a strong adhesive material prepared by adding olefins such as ethylene and propylene to the waterproof reinforcing layer. The amorphous polyolefin (APO) The conductivity of the heat transmitted to the inside is lowered to minimize the change in the temperature acting on the protective material P.

Hereinafter, one embodiment of the waterproof reinforcing layer will be described.

According to the above example, 1 kg of a waterproof strengthening layer was prepared by mixing 30 g of pozzolan, 40 g of paraffin, 20 g of styrene plastic elastomer, 35 g of an amine curing agent and 30 g of an amorphous polyolefin to prepare a waterproof reinforcing layer, Water was sprayed onto the outer surface of the protective material P on which the waterproof reinforcement layer was laminated and the waterproof reinforcement layer was laminated on the outer surface of the first protective layer 1 as a result of spraying for 1 hour, As a result of observing the outer surface of the first protective layer 1, it was confirmed that the first protective layer 1 was not invaded at all.

According to the above embodiment, the manufactured waterproofing layer was applied between the second protective layer 2 and the adhesive layer 3, and water was applied to the outer surface of the first protective layer 1 for 1 hour in the same manner as described above The second protective layer 2 and the adhesive layer 3 were separated and observed after spraying. As a result, it was confirmed that they were not invaded at all.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
