である。2. Description of the Related Art At present, when constructing an embankment on a soft ground such as a swamp, a civil engineering sheet such as a woven fabric having water permeability and high tensile strength is laid on the soft ground and the embankment is constructed on it. There is a way. This is a method of preventing uneven settlement of the embankment and sliding failure by the tensile force of the civil engineering sheet.

て、一目ずつロープにて連結する方法が一般的である。[0003] In this method, a civil engineering sheet must be laid on the entire surface of the soft ground, and it is common to connect the civil engineering sheets in advance by a sewing process or the like in a factory, but still the same as the soft ground. It is impossible to sew a product having an area from the viewpoint of transportation, and it is necessary to connect civil engineering sheets at the construction site. The conventional method for connecting a civil engineering sheet at a construction site is 5 to 2 at the periphery of the civil engineering sheet.
It is common to attach eyelet metal fittings at intervals of about 0 cm and connect them one by one with a rope.

It takes a lot of work because ropes are used to connect each eyelet metal fitting at a time on a soft ground where workability is poor. Furthermore, since the eyelet metal fittings are spaced apart, after laying and connecting the civil engineering sheet, when the earth and sand are sprinkled onto the civil engineering sheet, the tensile force generated in the civil engineering sheet due to the weight of the earth and sand and the construction heavy equipment, There was a problem that it concentrated on the eyelet metal fittings and was destroyed from the vicinity of the eyelet metal fittings. Therefore, it is an object of the present invention to obtain a method for connecting civil engineering work sheets that has good workability at a construction site and has sufficient tensile strength at a connection portion.

To do. This civil engineering sheet will be brought to the construction site and laid on soft ground. Next, prepare pipes with slits in succession, put adjacent civil engineering sheets together, and put the slitted pipes in the corners of the civil engineering sheet so that the ropes around each other are inside the pipes. Insert in sequence.
