It is installed between the formed main insulation plate 331a, the bottom surface of the insulation plate 331a and the foundation concrete layer 10, and is drawn in from the first base plate 336 and the first base plate 336 to form a drainage path. It is also possible to apply a cup-shaped drainage plate 335 having a plurality of protruding first support pillars 337.

Hereinafter, the construction process of such groundwater drainage will be described through the structure of FIG. 1.

First, the main drain plate 31 in which the pile insertion hole 33 penetrated up and down is installed on the foundation concrete layer 10. Next, the pile member 40 is inserted into the pile insertion hole 33.

Here, in the state where the pile member 40 is first inserted into the pile insertion hole 33 of the main drain plate 31, it may be provided on the foundation concrete layer 10 above.

In addition, the pile member 40 is higher than the upper surface of the main drain plate 31 in a state where the pile member 40 is inserted into the pile insertion hole 33 of the main drain plate 31 to be in contact with the basic concrete layer 10 as described above. Apply what has been formed to have a length.

Next, after the installation of the main drain plate 31 in which the pile member 40 is inserted, the mesh plate 60 formed in the mesh shape is installed on the upper end of the pile member 40.

Subsequently, the upper protection concrete layer 20 is formed by pouring concrete on the pile member 40 and the main drainage plate 31 to a thickness such that the net board 60 is sufficiently covered.

The groundwater drainage device has a function of supporting the upper protective concrete layer 20 by the pile member 40 to suppress damage and deformation caused by the load of the main drainage plate 31 having a thermal insulation function, thereby reducing the space of the drainage path 32. It can be maintained, and the pile member 40 inserted into the main drainage plate 31 can flow up and down through the pile insertion hole 33, so that the foundation concrete layer (regardless of the surface curvature of the foundation concrete layer 10) It can be installed in close contact with the upper surface of 10) it can also suppress the occurrence of cracking due to the vehicle dynamic load or impact load applied through the upper protective concrete layer (20).

In addition, the lifting phenomenon due to the surface curvature of the foundation concrete layer 10 is prevented by the pile member 40 flowing up and down, so that the size of one main drain plate 31 can be increased, thereby providing an easy construction. do.

In addition, only the insulation material such as styrofoam generates a crack due to the vehicle load, but the construction is impossible, but by applying the pile member 40, it is possible to prevent the crack due to the vehicle load and to obtain an insulation effect.

In addition, the pile member 40 is installed between the base concrete layer 10 and the mesh panel 60 is inserted into the reinforcing bar to act as a spacer between the mesh panel 60 and the foundation concrete layer 10 by the upper protective concrete layer ( 20) provides sufficient stiffness to prevent cracking, and because of the high strength made of materials such as PVC described above, unlike the concrete, the cracking caused by dry shrinkage and temperature change due to long-term wet repetition As a result, the load bearing capacity can be kept constant over time.
