专利汇可以提供Drain material for use in a water-containing poor subsoil and a method for installing said drain material therein专利检索，专利查询，专利分析的服务。并且There are disclosed a drain material and a method of installation thereof, in which a column-shaped or rod-shaped drain member of an extremely light and continuous cellular foamed synthetic resinous material is used as a drain material for withdrawing water from the water-containing poor subsoil to improve the strength or condition of the soil, thereby providing convenience for transportation and simplicity in working. For facilitating the insertion of the drain member into the watercontaining poor subsoil, a casing pipe having a lid member at its lower end is employed. When the casing pipe is withdrawn from the water-containing poor subsoil, the drain member is pressed down either by a weight secured to the lower portion of the drain member or by compressed air pressure thereon to prevent upward shifting caused by the frictional force between the drain member and the casing pipe.，下面是Drain material for use in a water-containing poor subsoil and a method for installing said drain material therein专利的具体信息内容。

权利要求

1. A method for installing a drain material in a poor subsoil which contains water so as to drain the subsoil of the water, comprising the steps of: a. driving vertically downwards through the soil to the subsoil an elongated casing having a lid with one portion of the lid pivoted to one end of said casing so that said lid is at the bottom and an open end of the casing is at the top, said lid having at least a second portion substantially opposite said pivoted portion extending outwards from the circumference of said lid in a plane substantially normal to the direction of elongation of said casing, there being inserted into said casing a continuous cellular foamed synthetic resinous drain material; and, b. withdrawing the casing from the subsoil, the pressure of said subsoil on said extending portion causing the lid to pivot open, so that said casing can be slipped out of the subsoil and soil leaving the drain material in place extending from the subsoil to the soil.

2. A method as claimed in claim 1 wherein said casing is first inserted into the subsoil and said drain material is then placed into said casing.

3. A method as claimed in claim 1 wherein said drain material is first inserted into said casing and said casing together with said drain is inserted into said subsoil.

4. A method as claimed in claim 1 wherein simultaneously with the withdrawal of said casing, compressed air is directed from above onto said drain material to maintain said drain material in place during the removal of said casing.

5. A method as claimed in claim 2 wherein simultaneously with the withdrawal of said casing, compressed air is directed from above onto said drain material to maintain said drain material in place during the removal of said casing.

6. A method as claimed in claim 3 wherein simultaneously with the withdrawal of said casing, compressed air is directed from above onto said drain material to maintain said drain material in place during the removal of said casing.

7. A method as claimed in claim 1 wherein a weight is placed at the bottom of said drain material prior to being inserted into said casing so as to maintain said drain material in place during removal of said casing.
