Abstract

PURPOSE:To prevent the occurrence of landslide, by a method wherein a communicating part, communicated with a part of a water non-permeable inner pipe, located in a water permeable outer pipe with a gap therebetween, and a joint between the outer and the inner pipe is attached to the communicating part. CONSTITUTION:A water non-permeable inner pipe 2 is inserted into an outer pipe 1, having an infinite number of through-pores 6 bored therein, with a water reverse flow gap (t) therebetween, and an opening, communicated with the gap (t), is formed in a part of the inner pipe 2 to from a communicating part 4. The outer pipe 1 is connected with a water non-permeable pipe 3 through engagement of the communicating part 4 with a funnel to form a water collecting joint 5. This enables water in a water-containing layer to flow through the gap (t) for drainage, and spring water on the upper stream side to flow through the inner pipe 2 for drainage to prevent the occurrence of landslide.

Description

【発明の詳細な説明】 「産業上の利用分野」 本発明は地すべり防止、地盤改良等の排水に用いる土木
用多重管に関するものである。DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to multiple pipes for civil engineering used for drainage for landslide prevention, ground improvement, etc.

含水層（地すべり地帯）の上方に湧水があると地すべり
対策が困難となった。``Conventional technology'' Conventionally, perforated drainage pipes have been used that are buried in landslide areas, ground improvement areas, etc. However, if there is a permeable layer in a part of the buried pipe, the water inside the pipe will flow out, and water will flow into the permeable layer, causing disasters such as landslides in that part.
Landslide countermeasures became difficult if there was spring water above the water-containing layer (landslide zone).

「発明が解決しようとする問題点」 本発明は埋設配管路中の含水層から透水層を経て上記配
管路外に排水しかつ上流湧水を安全に誘導することので
きる多重管を得ることを目的とするものである。"Problems to be Solved by the Invention" The present invention aims to provide a multilayer pipe that can drain water from a water-containing layer in a buried pipe through a permeable layer to the outside of the pipe and safely guide upstream spring water. This is the purpose.

てなる土木用多重管によって構成される。Means for Solving Problems J The present invention comprises a water-impermeable inner pipe provided within a water-permeable outer pipe through a gap, and a communication portion between the gap and the water-impermeable pipe. It is composed of multiple pipes for civil engineering, with a water collection joint between the outer pipe and the impermeable pipe provided in the section.

ない。``Function'' Therefore, water enters the gap from the water-containing layer of the landslide site etc. through the permeable outer pipe 1 and flows through the gap, and the inner pipe 2 collects spring water, etc. on the upstream side. Water flows. If there is a permeable layer in the underground pipe, at the boundary between the water-containing layer and the water-permeable layer, the water flowing from the water collection joint 5 in the gap t in the water-containing layer and the water flowing in the inner pipe 2 are transferred to the impermeable pipe. 3, flows through the inner pipe 3, and is discharged outside the pipe, so water flowing inside the pipe does not flow into the water permeable layer outside the double pipe.

湧水呑口である。``Example'' Water flows through the inside of the outer tube 1, which has countless small through holes 6.
A water-impermeable inner pipe 2 is inserted through the 1ft to form a double pipe. A part of the inner tube 2 has an opening that communicates with the gap t, forming a communication section t1. At this communication part, the lower end of a funnel as shown in FIG. What is shown by 7 in the figure is the spring water spout on the upstream side of the inner and outer pipes 1.2.

し得て透水層を安全に保持し得る効果がある。"Effects" Since the present invention is configured as described above, the water in the water-containing layer in the buried pipeline flows out from the IJt and the upstream spring water flows out into the inner pipe 2 to prevent landslides or improve the ground. Not only this, but also the water inside the gap in the water-permeable layer in the piping can be drained out of the piping without flowing out, and the water-permeable layer can be safely maintained.
