FIG. 1 is a partially enlarged view of a construction portion where a sheet is laid on the slope of an artificial pond. In the first embodiment of the construction method according to the present invention, the sheet is continuously laid not only on the slope but also on the bottom.

Generally, when constructing an artificial pond in a golf course or a garden, a waterproofing method is required to form a waterproof layer to prevent water from flowing out of the pond.

As this construction method, there is adopted a waterproof construction method in which after excavating the ground, a pebble or the like is laid to form a foundation, which is covered with a sheet to further form a soil layer on the sheet.

[0016] A long and wide sheet is required for the construction of a man-made pond, but since the width and length of the sheet produced in the factory are standard, the necessary amount of sheet is joined to the bottom of the pond. The work to do becomes necessary.

In the civil engineering method according to the present invention, a standard length sheet can be easily joined and embedded in a long and wide sheet, and the labor is saved and the efficiency is good.

The seat joint (1) of the first embodiment
Is provided with slits (s) in the long axis direction (t) of one long pipe (1a) over the entire length of the pipe. The width of the slit (s) may be such that the core material (4) around which the sheet (2) is wound does not come off the sheet joint (1). The width of the sheet is at least four times the thickness of the sheet, and the thickness of the sheet (2) and the like are various, so that a certain width is necessary so that various types of sheets (2) can be accommodated. is there.

The seat joint (1) of the first embodiment
Is not only the seat (2) but also the net (3) as shown in Fig.
It can also be used as a joining member for the net (3) and the sheet (2).

Seat joint (1) of the first embodiment
