In the case of rubber and asphalt, two spraying operations of mortar concrete and rubber asphalt are necessary,
The construction takes time, and the deterioration of the mortar / concrete layer 13 causes cracks in the rubber / asphalt layer 14, causing leakage of pollutants, and the original purpose cannot be achieved.

In addition, it is difficult to check whether the joints between the sheets are securely adhered to each other.
Since the sheet 15 is laid on the ground 1, the waste B
In the process where the dumping is performed as needed, the sheet 15 is easily damaged by the weight of the waste B, the weight compaction of the leveling machine C and the pebbles of the ground 1, and further, it is necessary to confirm the position of the damage and repair it. There is a problem that it is extremely difficult.

Excavated a relatively steep recess, and 3-10% by weight of silica fume and 0.8% of cement, sand and cement.
A spray material prepared by mixing steel fiber and water in an amount of up to 2.0% by volume is prepared, and the spray material is sprayed on the surface of the recess with high-pressure air of 7 to 10 kg / cm 2 to form a surface layer. After the surface layer is solidified, rubber asphalt is sprayed, and the waste is dumped in the recess. The surface of the dumped waste is leveled to a soft permeable clay having a thickness of 0.5 to 1.0 m. It is to be covered with wood covering soil.

Is done. Therefore, the surface layer is prevented from being damaged due to the weight of the waste and the like, and the slope of the slope portion can be constructed with a steeper slope than before, and the possible amount of waste to be dumped increases. And, since the water shielding property is sufficiently maintained, the pollutant does not leak.

が固化した後に、ゴム・アスファルトを散布する。Referring to FIG. 1, a recess 2 having a relatively steep slope of 1: 0.5 to 1.0 is excavated in the ground 1. Next, a spray material is sprayed on the surface of the concave portion 2 to form a surface layer 4 having a uniform thickness. The spraying material is, for example, 380 to 450 kg / m 3 of cement, 4 times the sand of cement, 3 to 10% of high-purity silica fume (% by weight based on cement), 0.8 to 2.0% by volume of steel fiber, and water. Are sequentially mixed for a predetermined time. Then, the spraying material is sprayed with a high-pressure air of, for example, 7 to 10 kg / cm 2 onto the surface of the concave portion 2 with a predetermined thickness by a pressure-resistant hose. And surface layer 4
After solidification, rubber and asphalt is sprayed.
