Description

  The present invention relates to a surface treatment material for soft ground.

  Conventionally, in order to reinforce the surface layer of soft ground, a surface reinforcing material is laid on the ground, and a surface treatment bag body placed on the surface of the surface reinforcing material is filled with a fluidized solidifying material to reinforce the surface processing. There was a method of forming the material. (For example, refer to Patent Document 1).

  By laying the surface treatment reinforcing material on the soft ground, it was possible to suppress uneven settlement when covering the soil, prevent the sheet from breaking, and avoid the disappearance of the covering material. Further, when the roadbed and roadbed are constructed on the surface treatment reinforcement laid on the soft ground, it is possible to construct a traffic road having a sufficient supporting capacity to withstand the traffic load.

The connecting jig 3 is made of a relatively hard material such as vinyl chloride in addition to a metal having high rigidity such as iron or stainless steel. The fluidized solid material 11 is mortar or the like.

  The inner peripheral surface 5 of the connecting jig 3 is provided with irregularities 7 that are locking portions that prevent the bag body 1 from shifting. For example, the inner diameter 13 of the connecting jig 3 is smaller than the outer diameter 15 of the bag 1. The inner diameter 13 of the connection jig 3 is preferably about 90% of the outer diameter 15 of the bag body 1 in order to ensure the integrity of the connection jig 3 and the bag body 1 by friction. The length 17 of the connecting jig 3 is desirably about 10 times the outer diameter 15 of the bag body 1.

  The connection jig 3 is provided with a confirmation opening 8 at a portion where the vicinity of the end portion 10a of the bag body 1a is disposed and a portion where the vicinity of the end portion 10b of the bag body 1b is disposed. A pressure sensor 9 is installed in the confirmation port 8.

  The fluidized solid material 11 is filled in the bag body 1a and the bag body 1b. In the bag body 1 a and the bag body 1 b, the end portion 10 a and the end portion 10 b are abutted inside the connection jig 3.

The end surface of the cylinder 71 a disposed in the cylinder 71 b is processed by the capping 73. The capping 73 is processed by stitching the tip of the cylindrical body 71a. The overlapping length of the cylinder 71a and the cylinder 71b is, for example, about 20 times the diameter of the cylinder 71a. The band 81 is a string, a metal wire, or the like.

  In order to form the surface treatment material 72, first, as shown by an arrow G in FIG. 8, the fluidized solid material 75 is filled into the cylinder 71 a, and the end surface of the cylinder 71 a is processed by the capping 73. Next, the end 77 a of the cylinder 71 a is inserted into the end 77 b of the cylinder 71 b and fixed with the band 81. Then, as shown by an arrow H in FIG. 8, the fluidized solid material 75 is filled into the cylindrical body 71b.

  Since the cylinder 71a and the cylinder 71b are made of a material having no watertightness, the strength of the fluidized solid material 75 filled therein is increased by dehydration. After the fluidized solid material 75 is solidified, the cylindrical body 71a and the cylindrical body 71b and the fluidized solidified material 75 are secured together by adhesion.

  As described above, according to the fifth embodiment, the weak portions are formed between the cylinders 71 filled with the fluidized solidifying material 75 even when the work space, the production capacity of the fluidized solidified material 75, and the like are limited. It is possible to form the surface treatment material 72 by unifying them. By using the surface treatment material 72 formed by integrating a plurality of cylindrical bodies 71, a uniform reinforcing effect can be obtained over a wide range.
