摘要： PURPOSE:To shorten the period of construction by fixing both end parts of reinforcing bars penetrating through the head part of a banking to a wale arranged on the slope, and fixing exposed end parts of anchor-reinforcing bars on the slope through bag-bodies packed with mortar. CONSTITUTION:Both end parts of respective reinforcing bars 1 nearly horizontally penetrating through the head part of a banking body are exposed from the banking body. Then, along the direction of extension of the banking body, a wale 2 is arranged on the upper end part of the slope on both sides of the banking, and respective end parts of the reinforcing bars 1 are fastened to the wale 2. Anchor-reinforcing bars 31 are then fixed on the slope beneath the wale 2 so that the bars are inclined downward. After plural drain materials 4 are arranged on the slope, bag-bodies 5 are installed over the drain materials 4, and the bag-bodies 5 are pierced with the exposed end parts 35 of the reinforcing bars 31. Further, after mortars 51 are injected into the bag-bodies 5, pressure bearing plates, nuts, etc. are mounted to the exposed end parts 35.

CONSTITUTION:A slope face 1 is digged from the uppermost shoulder at a new angle to be corrected, a free-to-fold holding sheet pile 2 is applied onto a digged face to cover the face. Next, anchor bolts 4 are inserted into the inside of a bank through a clearance between the horizontal members of the sheet pile 2, and curing agent 5 is filled around the bolts 4 to fix them to the ground. Then a plate 6 is fixed onto the head of the anchor bolt 4 exposed from the sheet pile 2, and an excess amount of the sheet pile 2 is folded. The second stage digging is made and the sheet pile 2 is expanded or connected.

摘要： PURPOSE:To improve the strength and execution property by intruding a cylindrical core material into a columnar improving body stirred and mixed with a solidifying agent into soil, and sticking the improving body to the inner and outer peripheries of the core material. CONSTITUTION:The upper section of a gentle slope 21 is cut off to form a cut slope 20 at such a gradient that a cut slope section is not collapsed. An excavating/stirring device 30 is rotated, excavating blades 32 are intruded into the slope 20, a solidifying agent is discharged from the tip of a hollow rod 31, and the solidifying agent and excavated soil are stirred and mixed to form a cylindrical improving body 11. The device 30 is drawn, and a cylindrical core material 12 is intruded into the improving body 11 before hardening to form a reinforcing body 10. These processes are repeated to expand the slope 20 in sequence, and a retaining wall is constructed on the slope 20 as required. The inner and outer peripheries of the core material 12 serve as friction resistance faces, the draw resistance force can be increased, resistance bending moment can be increased because of the cylinder, bending/shearing resistance force can be increased by the synthetic effect with the improving body 11, and the loosening of the peripheral ground during execution can be prevented.

摘要： PURPOSE:To make construction work easily by inserting a steel sheet-pile from the upper side of a slope face downwards into the slope face at a new angle to be corrected, digging the removing sediment outside the steel sheet-pile, and fixing the steel sheet-pile to the ground by means of an anchor bolt. CONSTITUTION:A steel sheet-pile 2 for the first stage H1 is driven downwards from the uppermost shoulder of a slope face 1. Next, the ground is digged by an amount of below half of the length of the driven steel sheet-pile 2, sediment is removed to the front surface of the steel sheet-pile, and cement mortar is spraying onto the digged surface. A hole is drilled from the outside of the steel sheet-pile into the inside of a banking. Then an anchor bolt 3 is inserted into the hole, curing agent 4 is filled around the bolt 3 to fix it to the ground, and a supporting member is attached to the head of the bolt 3. After driving the steel sheet-pile 2 for the second stage H2, the same work procedure is repeated.

摘要： PURPOSE:To simplify the operations by arranging supporting members between self-supporting form materials and drainage material side in which planar reinforcing materials are wrapped, removing the supporting members after construction of a banking body, and placing concrete between the form materials and the drainage materials. CONSTITUTION:A pit is excavated to install form materials 1 such as concrete panels, etc., into it, and then refilled to make the form materials self-supporting. Next the supporting members are arranged on the banking-body construction side of the form materials 1 through wedges, drainage materials 6 are wrapped up in the end parts of planar reinforcing materials 5, and banking materials 7 are laid over the other parts to construct a banking body. Further, each time one layer of the banking is constructed, the wedges and the supporting members are removed to be used for constructing the upper stages of the banking. After the removal of the supporting members, concrete is placed between the form materials 1 and the drainage materials 6 to construct a body concrete 8. Thus, the need for reaction force at the time of concrete placing can be eliminated to simplify the work.

摘要： PURPOSE:To reduce the construction period and the construction cost by throwing banking materials on a reinforcing sheet in one end of which sandbags are wrapped, to construct a banking body, thereafter mounting forms along the slope by means of spacer-rods capable of being expanded and contracted to construct a retaining wall. CONSTITUTION:Banking materials 3 are thrown on a water-permeable reinforcing sheet 2 such as geo-textile, etc., in one end of which sandbags 1 are wrapped, up to the same height as that of the sandbags 1. In this case, the upper stage of a banking is shifted inward from the lower stage to repeat the operations in sequence to pile up the banking body. After construction of the banking body, the end parts of the reinforcing sheet 2 are pinched by steel plates of the end parts of spacer-rods 4 to be connected to the slope of the banking body. Then, the spacer-rods 4 are expanded and contracted to position forms 6 along the slope at fixed intervals, and between the formes and the slope concrete 71. is placed to construct a retaining wall 7. The concrete placing pressure can thus be applied to the banking body, and thereby the retaining wall 7 can be positively constructed.
