【００２９】
【発明の実施の形態】
以下、本発明に係る実施の形態を詳細に説明する。
本実施の形態に係る地盤振動対策用土２０は、土砂を主材とし、水（又は例えば調整水）、固化材としてのセメント、混和剤を加えて混練して形成したソイルモルタルに、添加物として弾性材（例えばゴムチップ片又は古タイヤのチップ片等）及び／又はプラスチックの発泡ビーズ（例えば発泡スチロール又は発泡ウレタン等）を混練し、バインダーとしてラテックス（例えば合成ゴム製等）を混練して構成している。
【００３０】
一般的なソイルモルタルとは、建設現場で発生した土等に固化材を混合して建設資材として再利用する方法の用いるためのものであり、例えば単に土とセメントを混合したものをいう。
【００３１】
主材である土砂は、主に公知の処理を施した土、土砂、或いは高含水比の粘土、シルト等を用いるが、これに限らず広く一般の発生土自体を用いることもできる。
【００３２】
前記調整水とは、各材の分離を防止するために比重を調整した水である。また、この場合、主材である土が砂質土系の土の場合、各材の分離を防止するために比重を調整した水を添加し、一定量の細粒分を確保して処理したような比重を調整した水も使用できる。
【００３３】
また、地盤振動対策用土２０を構成する各材の配合比は、適用される地盤の地質や、発生する振動の想定値等によって種々に変更されるものである。
【００３４】
バインダーとしてのラテックス（変成ＳＢ中スチレン）は、例えば液状のラテックス（合成ゴム微粒子を水中に分散したもの）を使用する。
このラテックスとしては、例えば、全固形分４５（％）、ｐＨ１０．０、比重約０．９９、粘度２０（ｍＰａ・ｓ）、表面長力（ｍＮ／ｍ）、平均粒径２００（ｎｍ）、Ｔｇ−１５（℃）のものを用いる。
バインダーとしてのラテックスは、この他、粉状、エマルジョンのラテックスを用いることができる。
【００３５】
ラテックスは、地盤振動対策用土２０の各材を分離させることなく接着する性質を有し、且つ、当該各材の弾性作用を阻害しない機能やクラック発生を防止する機能等を発揮する。
【００３６】
本実施の形態では、前記ソイルモルタルと弾性材（例えばゴムチップ片又は古タイヤのチップ片等）及び／又はプラスチックの発泡ビーズ（例えば発泡スチロール又は発泡ウレタン等）との分離をなくすためには、固化材としてのセメントだけでは不十分であることからラテックスを用い、しかも、ソイルモルタルを極端に硬化又は固化したのでは振動吸収作用を発揮させることができなくなるが、ラテックスの弾性作用でかかる不都合を無くし、各材の接着作用をも発揮しながら、効率よく振動吸収可能とするものである。
【００３７】
そして、図１に示すように、例えば、線路６又は道路１とビル２との間において、地盤１０に、線路６又は道路１に沿うようにして所定深さの充填穴３を掘削し、この充填穴３内に、本実施の形態に係る地盤振動対策用土２０を打設し、固化させる。これにより、前記線路６又は道路１とビル２との間に地盤振動対策用土２０からなる地盤振動対策地中壁１１が構築される。
この場合、地盤振動対策地中壁１１は、後記するように充填穴３の周囲の他底面にも用いることができる。
【００３８】
上述のようにして構築した地盤振動対策地中壁１１において、鉄道車輛７又は車輛４の走行に伴って道路１に発生した振動が地盤１０へ伝播し、前記地盤振動対策地中壁１１へ至り、更にビル２側へと伝播するが、地盤振動対策地中壁１１を構成する地盤振動対策用土２０中のバインダーとしてのラテックスにより本来の機能を保持されたゴムのチップ片や古タイヤのチップ片、発泡スチロール又は発泡ウレタン等の弾性作用で、前記振動が効果的に吸収されることにより、前記振動がビル２側へ伝播することが抑制される。
【００３９】
また、古タイヤのチップ片、廃材からなる発泡スチロールを用いて地盤振動対策用土２０を構成した場合、地盤振動対策用土２０を廃材を利用して低価格で構成できる利点がある。
【００４０】
本実施の形態において示した各構成材の諸形状や寸法等は用途等に基づき種々変更可能である。
本発明では、本実施の形態に係る地盤振動対策用土の適用対象としては、図１に示す他、図２に示すように、例えば、ビル２の地下周囲の地盤１０に、所定深さの充填穴３を掘削し、この充填穴３内に、本実施の形態に係る地盤振動対策用土２０を打設し、固化させることにより、例えば地下鉄５が惹起する振動に対処するためのものとして地盤振動対策用土２０からなる地盤振動対策地中壁・底壁３１が構築される。
【００４１】
この場合の地盤振動対策地中壁・底壁３１は、ビル２の地下部分の周囲及び底面全体を含むものである。
【００４２】
この場合においても前記したと同様に、振動が効果的に吸収されることにより、この振動がビル２側へ伝播することが抑制される。
【００４３】
本実施の形態に係る適用対象としては、上下水道、ガス管、電力ケーブル、通信ケーブル等のライフラインの共同溝、地下駐車場、地下構造物、トンネル等を挙げることができる。
【００４４】
【発明の効果】
請求項１乃至６記載の各発明によれば、バインダーとしてラテックスを用いることにより、ゴムチップ片又は古タイヤのチップ片、廃材からなる発泡スチロール又は発泡ウレタンの弾性作用で優れた振動抑制作用を有し、しかも、廃材利用による低価格の地盤振動対策用土を得ることができる。
【００４５】
請求項７乃至１９記載の各発明によれば、前記請求項１乃至６記載の低価格の地盤振動対策用土を用いることによって、車輛等の走行に伴って道路等の地盤に発生する振動が、隣接する地盤へ伝播することを効果的に抑制することができる地盤振動対策地中壁・底壁及びその施工法を実現することができる。

[0029]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments according to the present invention will be described in detail.
The soil vibration countermeasure soil 20 according to the present embodiment includes soil and sand as a main material, water (or adjusted water, for example), cement as a solidifying material, and a soil mortar formed by kneading with an admixture as an additive. An elastic material (for example, a rubber chip piece or an old tire chip piece) and / or a plastic foam bead (for example, polystyrene foam or urethane foam) is kneaded, and a latex (for example, made of synthetic rubber) is kneaded as a binder. Yes.
[0030]
A general soil mortar is used for a method of mixing a solidified material with soil generated at a construction site and reusing it as a construction material. For example, the soil mortar is simply a mixture of soil and cement.
[0031]
As the earth and sand as the main material, soil, earth and sand, or clay having a high water content, silt or the like subjected to a known treatment is mainly used, but not limited to this, widely generated earth itself can also be used.
[0032]
The said adjustment water is water which adjusted specific gravity in order to prevent isolation | separation of each material. In this case, when the soil that is the main material is sandy soil-based soil, water with adjusted specific gravity was added to prevent separation of each material, and a certain amount of fine particles were ensured and processed. Water with adjusted specific gravity can also be used.
[0033]
Further, the mixing ratio of each material constituting the soil vibration countermeasure soil 20 is variously changed depending on the geology of the applied ground, the assumed value of the generated vibration, and the like.
[0034]
As the latex (styrene in the modified SB) as the binder, for example, a liquid latex (a synthetic rubber fine particle dispersed in water) is used.
Examples of the latex include a total solid content of 45 (%), a pH of 10.0, a specific gravity of about 0.99, a viscosity of 20 (mPa · s), a surface strength (mN / m), an average particle size of 200 (nm), The thing of Tg-15 (degreeC) is used.
In addition to this, latex in the form of powder or emulsion can be used as the binder.
[0035]
Latex has a property of bonding each material of the soil vibration countermeasure soil 20 without separating them, and exhibits a function of not inhibiting the elastic action of each of the materials, a function of preventing cracks, and the like.
[0036]
In the present embodiment, in order to eliminate the separation between the soil mortar and the elastic material (for example, rubber chip pieces or old tire chip pieces) and / or plastic foam beads (for example, polystyrene foam or urethane foam), a solidified material is used. As the cement alone is not enough, latex is used, and if the soil mortar is extremely hardened or solidified, it will not be able to exert vibration absorbing action, but the elastic action of latex will eliminate such inconvenience, The vibration can be efficiently absorbed while exhibiting the adhesive action of each material.
[0037]
Then, as shown in FIG. 1, for example, between the track 6 or the road 1 and the building 2, the ground 10 is excavated with a filling hole 3 having a predetermined depth along the track 6 or the road 1. The ground vibration countermeasure soil 20 according to the present embodiment is placed in the filling hole 3 and solidified. Thereby, a ground vibration countermeasure underground wall 11 composed of the ground vibration countermeasure soil 20 is constructed between the track 6 or the road 1 and the building 2.
In this case, the ground vibration countermeasure underground wall 11 can also be used on the other bottom surface around the filling hole 3 as described later.
[0038]
In the ground vibration countermeasure ground wall 11 constructed as described above, the vibration generated on the road 1 as the railway vehicle 7 or the vehicle 4 travels propagates to the ground 10 and reaches the ground vibration countermeasure ground wall 11. Further, the rubber chip piece and the old tire chip piece that have been originally functioned by latex as a binder in the soil vibration countermeasure soil 20 constituting the ground vibration countermeasure underground wall 11 are further propagated to the building 2 side. The vibration is effectively absorbed by an elastic action such as polystyrene foam or urethane foam, so that the vibration is suppressed from propagating to the building 2 side.
[0039]
In addition, when the ground vibration countermeasure soil 20 is configured using chip pieces of old tires and foamed polystyrene made of waste material, there is an advantage that the ground vibration countermeasure soil 20 can be configured at low cost using the waste material.
[0040]
Various shapes, dimensions, and the like of each constituent material shown in the present embodiment can be variously changed based on applications.
In the present invention, as an application target of the ground vibration countermeasure soil according to the present embodiment, as shown in FIG. 2, for example, the ground 10 around the basement of the building 2 is filled to a predetermined depth as shown in FIG. 2. By excavating the hole 3 and placing and solidifying the ground vibration countermeasure soil 20 according to the present embodiment in the filling hole 3, the ground vibration is used to deal with vibration caused by the subway 5, for example. A ground vibration countermeasure underground wall / bottom wall 31 composed of the countermeasure soil 20 is constructed.
[0041]
The ground vibration countermeasure underground wall / bottom wall 31 in this case includes the periphery and the entire bottom surface of the underground portion of the building 2.
[0042]
Also in this case, as described above, the vibration is effectively absorbed, so that the vibration is suppressed from propagating to the building 2 side.
[0043]
