本考案は、傾斜面の表面すべり防護策としての
暗渠排水可能な土留め用柵渠体に関する。[Detailed Description of the Invention] TECHNICAL FIELD OF THE INVENTION The present invention relates to an earth retaining fence culvert capable of underdrain drainage as a surface slip protection measure on an inclined surface.
背景技術
従来からの宅地造成、道路建設などの土木工事
における盛土斜面は人工的に作りあげるものであ
つて、自然斜面と違いその安定には特に留意すべ
きである。そのためには盛土資料の選定、締め固
めおよび斜面勾配などを適正にする必要がある。
各々問題点をあげると、
盛土資料の選定
経済的規制がなければ良質の資料を選べばよい
が、その規制を無視することは不可能で勢い最低
ぎりぎりの線で折合い、使用してしまう場合が多
い。これは、工費節減のためやむおえないことで
ある。BACKGROUND ART Embankment slopes used in conventional civil engineering works such as residential land development and road construction are artificially created, and unlike natural slopes, special attention should be paid to their stability. To this end, it is necessary to select appropriate embankment materials, compaction, and slope slope.
The problems for each are as follows: Selection of embankment materials: If there are no economic regulations, you can choose high-quality materials, but if it is impossible to ignore the regulations and you end up making compromises and using the materials at the bare minimum. There are many. This is unavoidable in order to reduce construction costs.
締固め
本来ならば充分時間をかけて盛土の落着き安定
を待つことができたが、近年ではいずれも緊速施
工にて機械による締固めを行つている。 Compaction Originally, it was possible to wait for the embankment to settle down and become stable, but in recent years, compaction has been carried out mechanically as an urgent construction method.
盛土本体の締固めはよいとして、法面の場合は
作業が難しいのでどうしても不充分になりがちで
ある。 Although compaction of the embankment itself is good, it tends to be insufficient when working on slopes because it is difficult to compact the earth.
法面勾配
盛土資料に従い勾配が決定されるのが原則であ
つたが、用地高騰に伴い勾配もぎりぎりの線で決
定される場合が多い。 Slope Slope In principle, the slope was determined according to the embankment data, but as land prices have risen, the slope has often been determined at the very edge.
以上のことを考慮し計画され、施工されるので
あるが、盛土本体は以上の他に盛土基盤の良し悪
しによつても、その安定が左右される。 The above factors are taken into consideration when planning and construction, but the stability of the embankment itself is also affected by the quality of the embankment foundation.
盛土斜面の安定を崩す要因はただ１つ、水とい
つても過言ではなかろう。降雨、降雪などによる
表面水（エロージヨン）、浸透水（締固めの軟弱
化によるエロージヨン、間〓水圧によるせん断抵
抗の低下および粘着力の減少など）が原因となつ
た、または原因となりそうな不安定要素をもつた
盛土法面には当然防護工が必要となる。防護工は
エロージヨン防止のための植生工は必要不可欠と
しても、法面不安定の要因たる水を処理する積極
的な防護工が必要である。コンクリートブロツク
による被覆工、格子枠工あるいは竹その他の編柵
は、浸透した水を処理することができない消極的
な防護工と言わざるを得ない。 It is no exaggeration to say that there is only one factor that can disrupt the stability of an embankment slope: water. Instability caused or likely to be caused by surface water (erosion) due to rain, snowfall, etc., seepage water (erosion due to weakening of compaction, decrease in shear resistance and decrease in adhesive strength due to water pressure, etc.) Naturally, protection works are required for embankment slopes with elements. As for protection works, although vegetation works are essential to prevent erosion, active protection works are needed to treat water, which is a cause of slope instability. Covering with concrete blocks, latticework, or bamboo or other woven fences must be considered negative protection works that cannot treat infiltrating water.

As shown in FIG. 5, the fitting parts 6 and 7 can be fitted into each other, and the height can be changed by fitting a plurality of stages (two stages in this example) together. . The net 8 made of synthetic resin or the like is the first
It is used by being fitted between the linear edges of the upper wall A, the first lower wall B, and the second upper wall Aa and second lower wall Ba that extend downwardly from the first lower wall B. This serves as a filter to prevent soil particles from entering the waterways 2, 2a when the soil is backfilled.
The water collection surface 16 formed by the first upper wall A, the net 8 and the first lower wall B is inclined forward at an angle θ with respect to the plate-like body 15 of the fence body 1.

However, only a slight amount of deflection occurs. The first and second support protrusions 3 and 3a prevent the first upper wall A and the second upper wall Aa from bending inward due to earth pressure. In addition, the first and second support protrusions 5, 5a similarly prevent the first and second lower walls B, Ba from bending inward, and ensure a sufficient drainage area of the first and second water channels 2, 2a. established for the purpose of

傾斜形成するものとしている。 Since the water collection surface 16 is formed at an angle θ with respect to the plate-shaped body 15, in terms of water collection efficiency, it is best to provide it perpendicularly to the slope where slope collapse is to be prevented. However, from an actual construction point of view, it is often difficult to construct multiple tiers such as 2 or 3 tiers, so we decided to form the sloping structure in consideration of two aspects: construction and water collection efficiency.

である。 FIG. 6 is an enlarged side view of the fence body 1. A receiving portion C that extends upward along the longitudinal plate-like body 15 is formed at the tip portion of the guide portion 18 into which the net 8 of the first lower wall B fits. The purpose of forming this receiving part C is that since the amount of water that permeates on the slope is too small to flow, the water that flows down along the fine mesh is absorbed by the surface tension on the mesh 8. It forms a thin film,
This prevents water from entering the water channels 2 and 2a, so the purpose is to serve as a drain to prevent this.

The figure is a lateral sectional view of the connecting portion, and FIG. 9 is a longitudinal sectional view of the connecting portion. The stakes 9 are made of pine logs, synthetic resin, etc., and are used as retaining stakes for earth retaining. The water collected by the water collection surfaces 16 of both the left and right fence bodies 1 buried in a figure eight shape is
Each water is collected in a collection pipe 10 and an underdrain drainage pipe 11.
This allows the water to flow down from the top to the bottom of the slope 17. The underdrain drain pipe 11 is made of a perforated pipe or a narrow pipe, and is surrounded by crushed stone 20 such as finely crushed gravel and is provided at the lowest part of the water collection pipe 10. After construction is completed, an embankment 21 is placed on the water collection pipe 10 so that grass and the like can easily grow there. The water thus collected by the underdrain drain pipe 11 of the water collection pipe 10 is discharged to the outside of the slope 17 by the drain pipe 12 at the lowest part.

る。 10 and 11 are a sectional view and a plan view of another embodiment of the present invention. If a large amount of rain or the like falls on the slope 17 when grass and the like are not sufficiently grown, the surface layer of the slope 17 is often destroyed by the sweeping force. As a countermeasure against this problem, various types of lattice frames are currently being used, such as concrete lattice blocks and resin lattice frames. A dovetail groove 22 having the same shape as the fitting part 7 of the fence body 1 is formed on one surface of the L-shaped member 13, and the other fitting part 6 of the fence body 1 is fitted into this dovetail groove 22. integrated,
It is buried within the inclined surface 17. By doing so, the L-shaped member 13 can form the reservoir waterway portion 23. This L-shaped member 13 and the fence body 1 are connected together using the connecting member 14 shown in FIGS. 12 and 13.
They can be inserted in any direction without water leakage, combined in a diagonal grid pattern, and placed on an inclined surface. The connecting member 14 has fitting holes 24a, 24b, 24c, and 24d on its side, into which the ends of the fence body 1 fit, and these fitting holes 24a to 24d are arranged at right angles to each other in the connecting part 25. It's communicating. The fitting holes 24a to 24d are marked with reference numbers 13a, 13b, 13c, and 13d in FIG.
The L-shaped member shown in is partially fitted. L-shaped members 13a to 13d in this fitted state
The free ends of are designated by reference numerals 26a to 2 in FIG.
6d. In the axial direction of the connecting member 14,
An insertion hole 27 is formed into which a stake is inserted.
The pile is driven into the soil through the insertion hole 27. An L-shaped projection 29 is formed on the top 28 of the connecting member 14, and this projection 29 connects the L-shaped members 13a to 1.
It connects to the protrusion formed in 3d. Therefore, the water flowing down from rain flows through the protrusion 29 and the L-shaped members 13a to 1.
It flows down along the protrusion 30 of 3d, and does not flow all at once from the upper part of the slope to the lower part, and the reservoir waterway part 2
3 flows. In addition, the infiltrated water is removed from the water channel 2 of the fence body 1.
2a, on the slope and inside the slope.
It becomes possible to treat water at certain locations. Therefore, the sweeping force of the water flowing down the slope 17 can be reduced, making it possible to prevent the slope from collapsing.

It also prevents clogging, and since the net is installed at an angle and comes with a drainer, it is possible to further improve the water collection effect.In addition, retaining piles for earth retention are driven at the same time, making it easier to use underdrains. As a result, earth retaining materials that also serve as soil retaining materials can be obtained.
