The present invention relates to a waterproof molded sheet for reinforcing a bridge end and a bridging waterproofing method using the same. More particularly, the present invention relates to a bridging waterproofing sheet for reinforcing bridges, A waterproof molded sheet for reinforcing a bridging end to prevent foreign matter such as excellence and calcium chloride from penetrating by sealing a gap between a barrier wall or a median separator and a bridge top plate by using a waterproof molded sheet for melting and integrating will be.
Generally, a waterproof layer of a bridge, that is, a waterproof layer of a concrete bottom plate, is complicated such as mechanical action such as repeated load, vibration, shock and shear caused by live load of a vehicle, weather phenomenon such as temperature change, It protects the bottom plate of bridges and protects the bridge asphalt layer to improve the durability of the bridge structure and the asphalt pavement layer.
The waterproof layer of such bridges basically has a waterproofing property capable of blocking moisture from the outside and capable of preventing permeation of substances such as calcium chloride for good weathering and snow removal from damaged parts, It forms a waterproof layer.
Such a waterproof layer is usually made of a hard waterproof layer. The sliding phenomenon at the waterproof layer interface can be prevented only when the integrated load behavior is performed because the vehicle load is repeatedly applied, so that the packing layer is prevented from being damaged.
When the adhesion between the interfaces is weak, water penetrated into the pavement surface and the joint portion is stagnated to promote the deterioration of the waterproofing material and the pavement layer, and the pavement of the pavement layer due to passage of time and vehicle traffic occurs, And cracked portholes occur in packaged asphalt.
In addition, the concrete deck may deteriorate the concrete due to the retained water and may cause the concrete alkali reaction.
As a waterproofing method for such bridges, a sheet type waterproofing, an infiltration waterproofing, a coating waterproofing, a combined waterproofing and the like are used, and depending on a construction method, there are a manpower construction and a mechanical construction method.
The above waterproofing methods are all performed to protect the bridge concrete slab structure and to improve the durability of the asphalt pavement layer from the load of the vehicle, the external weather, and the temperature.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of a waterproof molded sheet for bridging end bridging and a bridging waterproofing method using the same according to the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a partial cross-sectional view showing a cross-sectional waterproofing work using a waterproof molded sheet for reinforcing a bridge end according to the present invention, and FIG. 2 is a flowchart sequentially showing a cross-face waterproofing method using the waterproof molded sheet according to the present invention.
The present invention uses a waterproof molded sheet which is installed in a '?' Shape between the
That is, in the case of the road surface of the bridge, when the ambient temperature is 30 ° C, the temperature of the bridge increases to a maximum of 75 ° C, and thermal expansion largely occurs. The concrete, the ascon and the
In addition, both ends of the bridge are subjected to a periodic fatigue load due to the reciprocating motion of the vehicle due to the action of the momentum, so that cracks are generated or the
Therefore, in the present invention, the waterproof molded

More specifically, the mixture is heated to a temperature of about 200 to 250 DEG C in the range of 65 to 75 wt% of straight asphalt, 5 to 20 wt% of paraffin oil, 10 to 15 wt% of styrene butadiene styrene, and 1 to 5 wt% First, the above-mentioned straight asphalt has excellent elasticity and adhesiveness, so that the waterproof molded
If the content of the straight asphalt is less than 65% by weight of the total mixture, the elasticity and adhesion of the waterproof molded
The paraffinic oil serves to control the viscosity of the mixture. If the content of the paraffinic oil is less than 5% by weight of the total mixture, the dissolution at the asphalt packaging temperature may not be performed properly or the viscosity control ability may deteriorate. When the content of the blend exceeds 20% by weight of the total blend, the viscosity of the blend is lowered and the polyester nonwoven fabric is not impregnated properly.
Next, the styrene butadiene styrene (SBS) is a kind of thermoplastic elastomer, which can increase the elastic force of the polyester nonwoven fabric impregnated into the mixture, and can dissolve the mixture at the packing temperature of the asphalt .
The styrene-butadiene styrene also serves as a component of a coating-type waterproofing material to be described later, thereby improving the adhesion between the
If the content of styrene butadiene styrene is less than 10% by weight of the total mixture, the effect of increasing the elasticity of the polyester nonwoven fabric and improving the adhesion of the polyester nonwoven fabric to the
Next, the stabilizer is used for improving the heat resistance and durability of the material when mixing and heating the above-mentioned materials. In the present invention, the stabilizer is preferably selected from the group consisting of a carboxylic acid ester, a sulfone, a polyphosphoric acid, Three or more mixtures of asphalt (TLA) were used as stabilizers.
That is, the stabilizer can provide excellent heat resistance and chlorine resistance, can form a uniform thickness upon waterproofing the coating film, is excellent in stability against ultraviolet rays and heat, has good processability, And the layer separation phenomenon of the layer can be suppressed.
In addition, the stabilizer having the above-described structure has the ability to exchange anions, thereby being capable of capturing ions having weatherability when mixing straight asphalt, paraffin oil and styrene butadiene styrene, thereby improving long-term heat resistance .
At this time, the content of the stabilizer is preferably 1 to 5% by weight based on the total weight of the mixture.
In order to compare the stabilizer of the present invention with conventional stabilizers used in the prior art, a stirring test was conducted under different temperature conditions (200 ° C, 210 ° C, 230 ° C and 250 ° C), and the results are shown in Tables 1 to 4 below. .

Table 1 shows the results of stirring test of the stabilizer used in the present invention and the conventional general stabilizer at 200 ° C. In the case of the conventional general stabilizer, the viscosity rapidly decreases after 5 hours of heating and stirring. However, It can be confirmed that the viscosity of the stabilizer used is lowered after 8 hours of heating and stirring.
(1/10 mm)
Next, Table 2 shows the results of stirring test at 210 ° C. In the case of conventional general stabilizers, viscosity decreased and gelation occurred after 2 hours of heating and stirring. However, the stabilizer used in the present invention was heated for 5 hours It can be confirmed that the viscosity decreases later.

Next, the results of the stirring test at 250 ° C. are shown in Table 4. In the case of the conventional general stabilizer, the viscosity was rapidly lowered and gelation occurred after 1 hour of heating and stirring. However, It is confirmed that the viscosity decreases and the gelation phenomenon progresses after a lapse of time.
Therefore, the stabilizer used in the present invention has a good heat stability of the product even if it is heated for 3 hours on average compared with the stabilizers conventionally used, so that it is not only easy to apply in the field, It also has the advantage of easier maintenance.
