摘要： PROBLEM TO BE SOLVED: To preclude banking from collapsing from the slope, and rendering banking lightweight by enclosing mixed lightweight soil with a water-permeable synthetic fiber sheet at carrying out banking comprising mixed lightweight soil with a small piece of synthetic resin foam mixed to soil and sand. SOLUTION: A water-permeable synthetic fiber sheet (diotextile) 3 is wholly placed over the ground 4 to be given banking, and then banked on the water permeable synthetic fiber sheet 3 placed thereover is mixed lightweight soil 2 with at least a small piece of a synthetic resin foam mixed to soil and sand. The water permeable synthetic fiber sheet 3 is folded back to enclose the circumferential parts of the banked mixed lightweight soil 2 around the mixed lightweight soil 2 banked on the water permeable synthetic fiber sheet 3, then the banked mixed soil 2 is rolled by a bulldozer 5 or the like. Further, by covering the surface of the rolled mixed lightweight soil 2 with a remaining part of water permeable synthetic fiber sheet 3, the rolled mixed lightweight soil 2 is enclosed with the water permeable synthetic fiber sheet 3.

摘要： PURPOSE:To prevent excavation efficiency from deteriorating by locating excavating blades at one side end, the center portion, and the other side end of each connector in sequence from the direction of movement of chains, the excavating blades being secured to the connectors. CONSTITUTION:A pair of endless chains are arranged at predetermined intervals and parallel to each other around a support, and connectors 12 are used to join the adjacent endless chains together. One excavating blade 11 is secured to each connector 12, and the excavating blades 11 are secured to one side end, the center portion, and the other side end of the connectors 12 in sequence from the direction of movement of the endless chains. A total of two excavating blades 11 may be secured, one at one side end and the other at the other side end of each connector 12, and one excavating blade 11 may be secured to the center of each of the successive connectors 12 that adjoin each other along the direction of movement of the endless chains. Therefore, the excavating blades 11 resist clogging with earth and sand, and the efficiency of excavation can be prevented from deteriorating.

摘要： PURPOSE:To assemble a segment smoothly without any trouble even for assembly surfaces other than those of circular shape by combining the translational motion of a rotating body support body itself with the rotational motion of a rotating body relative to the rotating body support body. CONSTITUTION:With a segment held by a segment holding device 46, an erector ring support body 50 is moved in the direction roughly perpendicular to the propelling direction of a shield machine. Also this action is combined with the action to rotate an erector ring 48 supported by the erector ring support body 50 to position the segment holding device 46 at any location along the inner periphery of a skin plate 10. Then, under this condition, the segment holding device 46 is operated to move the segment roughly to the outward radial direction of the erector ring 48, and the segment is assembled.

摘要： PURPOSE:To prepare light weight solidified soil, which requires no special mixer, resists even high pressure feed, has high fluidity under a non-solidified state, has excellent workability due to high fluidity and has a wide applicability. CONSTITUTION:Soil, a solidifying material and water-absorbed and expanded gel-like resin granule are mixed, the mixture is transferred and charged to the position of execution under a non-solidified state, and left at stand and solidified, and bubble-shaped air gaps are formed in soil by the drying and shrinkage of resin granule after solidification. The method can be applied to the filling of a cavity section in the periphery of a structure with land subsidence. When the structure is supported by pile foundations 12 in a poor subsoil 10, the mixture is pressure-fed by a pump into the air gap generated between the ground and a footing 14 by the subsidence of the poor subsoil 10 to fill the air gap, and left at stand and light-weight solidified soil 16 is formed, thus filling the air gap section. The method can also be applied to other back-filling material, banking material, light-weight column, etc.

摘要： PURPOSE:To make anchorage of solid reinforcing material feasible by a method wherein a form is arranged on a threshold of an excavated groove, a blind cover is provided to an opening on the outside of the groove, the inside of the form is filled with filling agent, and a protection wall is formed to the surface of a natural ground except the place of the form. CONSTITUTION:An excavated groove 2 is formed and, at the same time, a belt-like reinforcing material 1 is inserted therein. A form 3 is placed on a threshold of the excavated groove 2, and a blind cover 6 is attached to the form 3. A grout hose 8 is inserted through an insert hole 10 provided to the blind cover 6, and filling agent such as grout is injected through the hose 8. Then a space around the belt-like reinforcing material 1 in the excavated groove 2 is filled therewith, and filling to the inside of the form 3 follows. After the filling is finished, the grout hose 8 is removed from the insert hole 10, and mortar 15 is sprayed to the natural ground surface Ms to construct a protection wall for the natural ground M. On spraying the mortar, the thickness of spraying is determined by using the outer edge of the form 3 as a ruler.
