    摘要： PURPOSE:To make up for shortage of tensile strength of a banking by eliminating scouring by rain water, etc., and degradation by lowering of the internal shearing strength by a method in which plural banking layers and plural ground reinforcing layers are alternately formed and a slope wall made of the same material as the reinforcing layer is formed even on the sloped portion. CONSTITUTION:A powdery granule 1 in dry state, not mixed with water, is spread over the surface of the bottom ground where banking is to be constructed, a tense material 2 is laid on the powdery granule and anchored, the powdery granule 1 is spread on the tense material 2, and the first banking layer is formed on the tense material 2. The banking layer A is formed till a position retracted from the final slope face, a front net 3, together with a formwork 4, is attached, and a powdery granule 1 of the same material as a reinforcing layer B is put between the net 3 and the first banking layer. Afterwards, the same operations are repeated to construct the second layer and higher layers to a target height. The water-absorbed ground reinforcing layers and the slope layer are strongly hardened together.

    摘要： PURPOSE:To construct an underground structure of a high strength at deep depth by a method in which precast concrete blocks are continuously set in excavating mud water, a prestress is given to the concrete blocks, and the mud water is hardened. CONSTITUTION:A prestress is given to precast concrete blocks 2 set in an excavated trench with an excavating mud water 3 in fluid state by using an unbond PC cable 4, and then the mud water 3 is hardened with a solidifying agent. The concrete blocks are restrained by the ground and an underground structure having a high strength can thus be constructed at deep depth.

    摘要： PURPOSE:To make easier the taking out of a filter by a method in which a large number of vertical parts of sufficiently smaller strength than a cross part are provided almost in orthogonal direction to the cross part of a spiral form to form a meshed filter, and the meshed filter is used as the water draining pipe. CONSTITUTION:A large number of vertical parts 1 are set in parallel with the axial direction of a cylindrical filter 3, and a continuous cross part 2 is spirally and almost orthogonally attached to the periphery of the vertical parts 1 to form a meshed filter 3 with integrated cross portions. The vertical parts 1 are sufficiently weaker in strength than the cross part 2. In exchanging the filter, the tail end of the cross part 2 is pulled out to the outside of the water drawing pipe 4, whereupon the vertical parts 1 are gradually broken because of their weaker strength, and the cross part 2 is taken out while being stretched into smaller diameters and the pulling force is orderly transmitted to the back side of the pipe 4. The filter 3 can thus be drawn out without discontinuation, and the exchange of the filter 3 can be easily made.

    摘要翻译： 目的：为了更容易地通过一种方法来取出过滤器，其中大体上具有比十字形部分强度小得多的垂直部分几乎与螺旋形状的交叉部分正交的方式形成网状过滤器， 并且使用网状过滤器作为排水管。 构成：将多个垂直部件1与圆筒形过滤器3的轴向平行设置，并且连续的横切部分2螺旋状并且几乎正交地附接到垂直部分1的周边，以形成具有 集成交叉部分。 垂直部分1的强度比横截面部分2弱得多。在更换过滤器时，横向部分2的尾端被拉出到抽水管4的外侧，于是垂直部分1逐渐断开，因为 其强度较弱，横截面2被拉伸成较小的直径，并且拉力有序地传递到管4的后侧。因此，过滤器3可以不中断地被抽出，并且交换 过滤器3可以容易地制成。
