Description

DETAILED DESCRIPTION OF THE INVENTION The invention relates to a method of constructing a drain near the end of a concrete slab coated with a bituminous concrete covering interposed with a waterproof layer.

The uninvented method is particularly suitable for concrete
For concrete joints with beton (beton), install a waterproof sheet (
(relevé d'étancheite),
For construction works with a slope of IX or higher, drains must be installed at the bottom end, and for slabs with a slope of zero, drains must be installed at both ends.

SUMMARY OF THE INVENTION The method of the present invention involves cutting the covering and the waterproof layer approximately perpendicularly to the upper surface of the slab to about 20 m, preferably 5 aN, from the groove edge of the slab, and cutting the waterproof sheet over one width of the slab. The waterproof sheet is applied to the upper surface of the slab and hot-applied, and the remaining width of the waterproof sheet is bent so that the remaining width is approximately parallel to the cut surface of the covering, in the short direction of the drain to be constructed. Spread it a distance corresponding to the dimensions, apply asphalt to the space between the cut part of the covering on the top of the slab and the waterproof sheet part that is almost parallel to the covering, and install a drain in this space. Finally, the waterproof sheet is applied around the drain, and is hot-applied to the cut surface of the covering at the end thereof.

It is particularly desirable to apply a bituminous adhesive coating to the top surface of the slab in the space prior to asphaltic application.

It is also desirable to blow air into the space before applying the asphalt to remove any water that may accumulate between the covering and the waterproof coating.

The thickness of the asphalt applied to the slab is approximately 1 to 50 m.
, preferably about 5 to 10 tones.

The method of the present invention generally uses a material that does not rust such as aluminum as a material, has a substantially rectangular cross section, and has a sawed (sciag)
Cuts ( e ) distributed in the longitudinal direction are formed by
It is carried out using a conventional type drain for road works, which is a profile with a fente).

The invention also provides a novel drain that can be installed in an alternative manner during the implementation of the method.

The drain of the present invention is characterized in that it is a continuous helical spring made of a rust-free material such as aluminum or stainless steel 914 tx.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Other advantages and features of the present invention will be made clear through the detailed description of the invention that will be developed below with reference to the accompanying drawings.

The drain shown in FIG. 1 is a generally rectangular cross-section made of a rust-resistant material such as aluminum.

A cut 2 is made in this profile by sawing K.

The novel drain 3 of the present invention shown in FIG. 2 is a seamless helical spring made of rust-free material such as aluminum or stainless steel.

This novel drain of the present invention can be applied in a variety of ways for a variety of applications, but especially when applied to a concrete joint with double concrete supports when installed according to the method of the present invention and when pouring concrete over the drain. It's advantageous. Considering the deformability of the drain 3, it was confirmed that the drain would perform excellently when applied to this purpose.

Reference is now made to FIGS. 3 to 6, which illustrate how to install the drain shown in FIG. 1.

The slab 4 of the concrete work is coated with a bituminous concrete covering 5 interposed with a waterproofing layer 6 of e.g. Eva epoxy resin; a bituminous felt sheet can also be inserted between the waterproofing layer 6 and the concrete IJ-toss slab 40.

As shown in FIG. 3, in carrying out the method of the present invention,
First, the covering body 5 and the waterproof layer 6 are attached to the groove edge (board) of the slab.
cut by a distance of d (for example, 5 pieces) from the feuillure.

Subsequently, as shown in FIG. 4, a part of the waterproof sheet 7 made of a composite material of aluminum and bitumen, for example, is applied to the upper surface of the slab and hot-applied, and the remaining part of the waterproof sheet 7 is Bend it so that it is almost parallel to the cut surface of the covering, and unfold it by a distance e from the covering 5 (for example, about 2 pieces, which corresponds to the lateral dimension of the drain to be constructed).

The next step is to apply a bituminous adhesive coating to the upper surface of the slab in the space between the section 9 of the sheet 70 and the cut surface of the covering 5, and after removing the air by blowing air into the space. Asphalt 10 is applied.

Afterwards, as shown in Figure 6, install drain 1 and
A waterproof sheet is hot-applied around the edge of the covering 5.
Just apply it to the cut surface.

By pouring concrete over the drain that has been installed, a waterproof joint that should be installed as a sheet at the end of the slab of the construction work will be completed.

The water that penetrates into the cladding 5 does not penetrate into the slab 4 (there is no risk of it flowing into the drain and damaging the slab by freezing).

Figure 7 is the same type of diagram as Figure 6, but the drain 3 in Figure 2
Shows the installed state.

It goes without saying that the procedure for installing the drain 3 is the same as that shown in FIGS. 3 to 5.

It goes without saying that the invention is not limited to the embodiments introduced above, and that various other embodiments are possible within the scope of the claims.
