Description

本発明は、高含水比の泥土を注入して袋詰め脱水を行う際に使用される泥土の袋詰め脱水用袋及びその袋詰め脱水処理方法に関し、特に、環境汚染物質を含有する泥土の脱水に有効な技術に関する。   The present invention relates to a mud bag for dehydration used when performing dehydration by injecting mud with a high water content ratio, and a dehydration treatment method for the mud, and in particular, dehydration of mud containing environmental pollutants. Related to effective technology.

河川、湖沼、海洋などで浚渫された高含水比の泥土の脱水処理としては、布帛等からなり透水性を有する袋体に、高含水比泥土をポンプ等により圧送して充填してから、袋体を一定期間放置する、いわゆる、袋詰め脱水処理が広く採用されている(例えば、特許文献1参照)。このようにして脱水された処理土は、袋詰め状態で盛土や埋土として積み重ねられたり、あるいは、覆土などとして有効利用される。   For dehydration treatment of mud soil with a high water content dredged in rivers, lakes, oceans, etc., after filling the water-permeable bag body with a high water content mud with a pump, etc. A so-called bagging dehydration treatment in which the body is left for a certain period of time is widely adopted (see, for example, Patent Document 1). The treated soil dehydrated in this manner is stacked as embankment or buried soil in a packed state, or is effectively used as covering soil.

特許第2535302号公報Japanese Patent No. 2535302

前述の袋詰め脱水処理では、袋体内に充填された泥土は、その水分が袋体の表面から蒸発することにより脱水されるが、この袋体内の中心付近に位置しており袋体の表面から離れた泥土の水分は蒸発しにくいために、脱水処理が完了するまでに長い時間がかかるという問題があった。   In the above-described bagging and dewatering treatment, the mud filled in the bag body is dehydrated as its moisture evaporates from the surface of the bag body. Since the water in the separated mud is difficult to evaporate, there is a problem that it takes a long time to complete the dehydration process.

本発明の目的は、袋体内に充填された泥土をより速やかに脱水することが可能な袋詰め脱水用袋を提供することである。   An object of the present invention is to provide a bag for bag filling and dewatering that can dewater the mud filled in the bag more quickly.

課題を解決するための手段及び発明の効果Means for Solving the Problems and Effects of the Invention

第1の発明の泥土の袋詰め脱水用袋は、高含水比の泥土を注入して袋詰め脱水を行うための袋であって、透水性を有する布帛からなり、その内部に泥土を注入するための注入口を有する袋体と、前記袋体内にその内部空間を横切るように配設され、且つ、前記袋体内に開口する開口部を有する筒状排水材と、その一端部において前記袋体の注入口と接続されるとともに他端部に設けられた連通口が前記筒状排水材の内部に開口し、前記袋体の注入口と前記筒状排水材の内部とを連通させて前記注入口に注入された泥土を前記筒状排水材に導く、筒状の連通材と、を備えていることを特徴とするものである。
A mud bagging and dewatering bag according to a first aspect of the present invention is a bag for performing bagging and dewatering by injecting mud with a high water content ratio, and is made of a water-permeable fabric, and mud is injected into the bag. A bag body having an injection port, a cylindrical drainage material disposed across the interior space of the bag body and having an opening opening in the bag body, and the bag body at one end thereof inlet and communicating port provided in the other end portion is connected is open to the interior of the tubular drainage member, said communicated between the interior of the tubular drainage member and the inlet of the bag Notes And a tubular communication material that guides the mud injected into the inlet to the tubular drainage material .

この袋詰め脱水用袋は、袋体内に高含水比の泥土が充填された後、泥土が十分に脱水されるまで一定期間放置される。ここで、袋体の内部空間の中心付近に位置する泥土は、袋体の表面から離れているために、表面付近の泥土と比べて脱水されにくい。しかし、この第1の発明の脱水用袋においては、袋体内にその内部空間を横切るように筒状排水材が配設されているため、袋体内に泥土が充填された状態で、その中心付近の泥土から水分が筒状排水材を伝って袋体の表面へ移動し、外部へ排出されるため、脱水時間が短縮される。   The bag for dehydration is left for a certain period of time until the mud is sufficiently dehydrated after the bag is filled with mud with a high water content. Here, since the mud located near the center of the internal space of the bag body is away from the surface of the bag body, it is less likely to be dehydrated than the mud near the surface. However, in the dewatering bag according to the first aspect of the present invention, since the cylindrical drainage material is disposed so as to cross the internal space in the bag body, the bag body is filled with mud and near its center. Since the water moves from the mud to the surface of the bag body through the cylindrical drainage material and is discharged to the outside, the dehydration time is shortened.

また、筒状排水材は袋体内に開口する開口部を有し、この筒状排水材の内部は、連通材を介して袋体の注入口と連通しているため、注入口から注入された泥土は、連通材及び筒状排水材を通って、筒状排水材の開口部から袋体内に充填される。そのため、袋体内に泥土が注入されていくにつれ、筒状排水材の内部にも泥土が充填されて膨張することになり、筒状排水材がその外側の泥土により押し潰されることなく袋体内で筒状に保持されるので、筒状排水材が袋体の内面に押しつけられることがない。従って、袋体内の泥土に含まれる水分が筒状排水材を伝ってスムーズに表面まで移動するため、脱水時間がさらに短縮される。   In addition, the cylindrical drainage material has an opening that opens into the bag body, and the inside of the cylindrical drainage material communicates with the injection port of the bag body via the communication material, so that the cylindrical drainage material was injected from the injection port. The mud is filled into the bag body from the opening of the cylindrical drainage material through the communication material and the cylindrical drainage material. Therefore, as the mud is poured into the bag body, the mud is filled in the inside of the cylindrical drainage material and expands, and the cylindrical drainage material is not crushed by the mud on the outside of the bag. Since it hold | maintains at a cylinder shape, a cylindrical drainage material is not pressed on the inner surface of a bag body. Accordingly, the moisture contained in the mud in the bag body moves smoothly through the cylindrical drainage material to the surface, so that the dehydration time is further shortened.

また、注入された泥土は袋体の内面に直接注入されず、連通材の内部及び筒状排水材の内部を経由して袋体の中に充填される。このため、注入された泥土の流れに乱れが発生せず、袋体の内面に形成された泥膜が破壊されないので、袋詰め脱水においてしばしば見られる注入開始直後の排出水の濁り(初期濁り)を効果的に抑えることができ、環境汚染物質を含有するような泥土の脱水に特に有効である。また、注入された泥土は、筒状排水材の中を通過する間に濾過されるので、これによっても濁りが除去される。   Moreover, the injected mud is not directly injected into the inner surface of the bag body, but is filled into the bag body through the inside of the communicating material and the inside of the cylindrical drainage material. For this reason, there is no turbulence in the flow of the injected mud, and the mud film formed on the inner surface of the bag body is not destroyed, so the turbidity of the discharged water immediately after the start of injection often seen in bagging dehydration (initial turbidity) This is particularly effective for dewatering mud containing environmental pollutants. Further, since the injected mud is filtered while passing through the cylindrical drainage material, the turbidity is also removed by this.

第2の発明の泥土の袋詰め脱水用袋は、前記第1の発明において、前記連通材の前記連通口は前記筒状排水材の一端部の内部に開口しており、前記開口部は前記筒状排水材の他端部に形成されていることを特徴とするものである。従って、注入口から連通材を介して筒状排水材の一端部内に流入した泥土は、この筒状排水材の内部を通って、他端部に形成された開口部から袋体内に流れる。そのため、袋体内に泥土が注入されていくにつれ、筒状排水材の内部に確実に泥土が充填されることから、筒状排水材が泥土により押し潰されることがなく筒状に保持され、袋体の中心付近の泥土に含まれる水分が筒状排水材を介してよりスムーズに袋体の表面へ移動し、外部へ排出される。 According to a second aspect of the present invention, there is provided a bag for dewatering and dewatering a mud according to the first aspect, wherein the communication port of the communication material is opened inside one end portion of the cylindrical drainage material, It is formed in the other end part of a cylindrical drainage material, It is characterized by the above-mentioned. Therefore, the mud that has flowed into one end portion of the cylindrical drainage material from the inlet through the communicating material flows into the bag body through the opening of the other end portion through the inside of the cylindrical drainage material. Therefore, as the mud is poured into the bag body, the mud is surely filled into the cylindrical drainage material, so that the cylindrical drainage material is held in a cylindrical shape without being crushed by the mud. Moisture contained in the mud near the center of the body moves more smoothly to the surface of the bag body through the cylindrical drainage material and is discharged to the outside.

第3の発明の泥土の袋詰め脱水用袋は、前記第1又は第2の発明において、前記袋体は、一方向に長い形状に形成されており、前記筒状排水材は、前記袋体の内部空間の中心付近を通って袋体の長手方向に延びていることを特徴とするものである。従って、袋体内に泥土が充填されて膨張した状態で、表面から最も離れた位置にある袋体の中心付近の泥土に含まれる水分が、筒状排水材を介して袋体の表面へ確実に移動し、外部へ排出される。また、袋体内で筒状排水材が短手方向に延びるように配設された場合と比べて、筒状排水材の長さが長くなるため、袋体内のより広い範囲の泥土から水分を表面まで移動させて排出することができるようになる。   According to a third aspect of the present invention, in the first or second aspect, the bag is formed in a shape that is long in one direction, and the cylindrical drainage material is the bag body. It extends in the longitudinal direction of the bag body through the vicinity of the center of the interior space. Therefore, in a state where the bag body is filled with mud and inflated, moisture contained in the mud near the center of the bag body farthest from the surface is surely transferred to the surface of the bag body through the cylindrical drainage material. It moves and is discharged outside. In addition, compared with the case where the cylindrical drainage material is disposed so as to extend in the short direction in the bag body, the length of the cylindrical drainage material is increased. It can be moved and discharged.

第4の発明の泥土の袋詰め脱水用袋は、前記第3の発明において、前記筒状排水材の長さは、泥土が充填された状態の前記袋体の長手方向の長さに略等しいことを特徴とするものである。そのため、袋体内に泥土が充填されたときには、袋体内部に配設された筒状排水材は袋体の長手方向に直線的に張った状態となるため、泥土に含まれる水分が筒状排水材を伝って確実に袋体の表面まで移動していく。   According to a fourth aspect of the present invention, there is provided the bag for dewatering and dewatering of mud according to the third aspect, wherein the length of the cylindrical drainage material is substantially equal to the length in the longitudinal direction of the bag body filled with mud. It is characterized by this. Therefore, when the mud is filled in the bag, the cylindrical drainage material disposed inside the bag is in a state of being stretched linearly in the longitudinal direction of the bag, so that the water contained in the mud is drained by the cylindrical drainage. It moves to the surface of the bag surely through the material.

第5の発明の泥土の袋詰め脱水用袋は、前記第1〜第4の何れかの発明において、前記袋体が、複数本の経糸とこれら経糸に対してスパイラル状に連続して織り込まれた緯糸からなる継ぎ目のない筒状織物からなることを特徴とするものである。縫製からなる既存の袋体では、ポンプの注入圧力が袋体に作用しない範囲の高さまで(充填された泥土の自重による引張力のみが脱水用袋に作用している範囲内で)しか充填作業を行えないが、この第5の発明の袋体はその耐圧力が高いために、ポンプ等の注入圧力が作用しても袋体は容易に破断せず、袋体が泥土の注入圧力により膨張して張った状態となるまで泥土を充填できる。このため、脱水用袋1つあたりの泥土の充填量を増やすことができる。さらに、泥土が充填されて膨張した脱水用袋内の泥土には高い圧力が作用しているため、この状態で放置されたときに泥土からの脱水が促進される。   According to a fifth aspect of the present invention, there is provided a bag for dewatering a mud bag according to any one of the first to fourth aspects, wherein the bag body is continuously woven in a spiral shape with respect to a plurality of warps and these warps. It is characterized by comprising a seamless tubular woven fabric made of weft. For existing bags made of sewing, filling work only to the extent that the pump injection pressure does not act on the bag (within the range where only the tensile force due to the weight of the filled mud is acting on the dewatering bag) However, since the pressure resistance of the bag of the fifth invention is high, the bag does not easily break even when the injection pressure of a pump or the like is applied, and the bag expands due to the injection pressure of the mud. The mud can be filled until it is stretched. For this reason, the amount of mud filling per dehydration bag can be increased. Furthermore, since a high pressure is acting on the mud in the dewatering bag filled with mud and expanded, dehydration from the mud is promoted when left in this state.

第6の発明の袋詰め脱水処理方法は、前記第1〜第5の何れかの袋詰め脱水用袋を用いて高含水比の泥土の袋詰め脱水処理を行う方法であって、前記注入口から前記連通材の内部及び前記筒状排水材の内部を経由して前記袋体内に泥土を注入して、前記袋詰め脱水用袋内に泥土を充填し、この袋詰め脱水用袋を放置することにより、その内部に充填された泥土の脱水を行うことを特徴とするものである。   The bagging and dehydrating method of the sixth invention is a method for performing a bagging and dehydrating treatment of mud with a high water content ratio using the bag for bagging and dehydrating of any one of the first to fifth items, wherein the inlet The mud is injected into the bag body through the inside of the communication member and the cylindrical drainage material, the mud is filled in the bag for dehydration, and the bag for dehydration is left unattended. Thus, the mud filled in the inside is dewatered.

注入口から注入された泥土は、連通材及び筒状排水材を通って、筒状排水材の開口部から袋体内に充填される。そのため、袋体内に泥土が注入されていくにつれ、筒状排水材の内部にも泥土が充填されて膨張することになり、筒状排水材がその外側の泥土により押し潰されることなく袋体内で筒状に保持されるので、筒状排水材が袋体の内面に押しつけられることがない。従って、袋体内の泥土に含まれる水分が筒状排水材を伝ってスムーズに表面まで移動するため、脱水時間がさらに短縮される。また、注入された泥土は袋体の内面に直接注入されず、連通材の内部及び筒状排水材の内部を経由して袋体の中に充填される。このため、注入された泥土の流れに乱れが発生せず、袋体の内面に形成された泥膜が破壊されないので、袋詰め脱水においてしばしば見られる注入開始直後の排出水の濁り(初期濁り)を効果的に抑えることができ、環境汚染物質を含有するような泥土の脱水に特に有効である。また、注入された泥土は、筒状排水材の中を通過する間に濾過されるので、これによっても濁りが除去される。   The mud injected from the inlet passes through the communication material and the cylindrical drainage material, and is filled into the bag body from the opening of the cylindrical drainage material. Therefore, as the mud is poured into the bag body, the mud is filled in the inside of the cylindrical drainage material and expands, and the cylindrical drainage material is not crushed by the mud on the outside of the bag. Since it hold | maintains at a cylinder shape, a cylindrical drainage material is not pressed on the inner surface of a bag body. Accordingly, the moisture contained in the mud in the bag body moves smoothly through the cylindrical drainage material to the surface, so that the dehydration time is further shortened. Moreover, the injected mud is not directly injected into the inner surface of the bag body, but is filled into the bag body through the inside of the communicating material and the inside of the cylindrical drainage material. For this reason, there is no turbulence in the flow of the injected mud and the mud film formed on the inner surface of the bag body is not destroyed. This is particularly effective for dewatering mud that contains environmental pollutants. Further, since the injected mud is filtered while passing through the cylindrical drainage material, the turbidity is also removed by this.

第7の発明の袋詰め脱水処理方法は、前記第5の発明の袋詰め脱水用袋を用いて高含水比の泥土の袋詰め脱水処理を行う方法であって、前記袋体内に泥土を注入し、その注入圧力により袋体が膨張するまで前記袋詰め脱水用袋内に泥土を充填し、この袋詰め脱水用袋を放置することにより、その内部に充填された泥土の脱水を行うことを特徴とするものである。本発明の袋体の耐圧力は通常の縫製等により作製されたものよりも高いために、ポンプ等の注入圧力が作用しても袋体は容易に破断せず、袋体が泥土の注入圧力により膨張して張った状態となるまで泥土を充填できる。このため、脱水用袋1つあたりの泥土の充填量を増やすことができる。さらに、泥土が充填されて膨張した脱水用袋内の泥土には高い圧力が作用しているため、この状態で放置されたときに泥土からの脱水が促進される。   The bagging and dehydrating method of the seventh invention is a method for carrying out bagging and dehydrating processing of mud with a high water content using the bag for dehydrating of the fifth invention, wherein mud is injected into the bag body. The mud filled in the bag is filled with mud until the bag body is expanded by the injection pressure, and the mud filled in the bag is dehydrated by leaving the bag for dehydration. It is a feature. Since the pressure resistance of the bag body of the present invention is higher than that produced by ordinary sewing or the like, the bag body does not easily break even when the injection pressure of a pump or the like is applied, and the bag body is injected with mud. It can be filled with mud until it is expanded and stretched. For this reason, the amount of mud filling per dehydration bag can be increased. Furthermore, since a high pressure is acting on the mud in the dewatering bag filled with mud and expanded, dehydration from the mud is promoted when left in this state.

本発明の実施の形態について図1〜図5を参照して説明する。
図1、図2に示すように、本実施形態の泥土の袋詰め脱水用袋1(以下、脱水用袋1という)は、その内部に泥土を注入するための注入口2aを有する袋体2と、この袋体2内にその内部空間を横切るように配設された筒状排水材3と、袋体2の注入口2aと筒状排水材3の内部とを連通させる筒状の連通材4とを有する。
Embodiments of the present invention will be described with reference to FIGS.
As shown in FIGS. 1 and 2, a mud bagging and dewatering bag 1 (hereinafter referred to as a dewatering bag 1) of the present embodiment has a bag body 2 having an inlet 2 a for pouring mud into the bag. A tubular drainage material 3 disposed in the bag body 2 so as to cross the internal space thereof, and a tubular communication material for communicating the inlet 2a of the bag body 2 with the interior of the tubular drainage material 3 4.

袋体2は、その両端部が夫々縫製により閉塞された、透水性を有する筒状織物10(布帛)からなり、その筒長方向(図2の左右方向)に長い形状に形成されている。この筒状織物10は、複数本の並列した経糸と、これらの経糸に対してスパイラル状に連続して織り込まれた緯糸からなる、継ぎ目のない筒状織物である。そのため、この袋体2は高い破断圧力を有しており、後述のように袋体2内にポンプ等の注入手段により泥土を加圧注入して膨張させても、袋体2が容易に破断しない。また、この袋体2は、その内部に泥土が充填されたときに(図5参照)、その短手方向(径方向)に膨張し、これによって、その長手方向(筒長方向)に収縮する。図1、図2に示すように、袋体2を構成する筒状織物10の一方の端部は折り曲げられた状態で縫製されており、この端部には、棒状の吊り具20が挿通される筒状の吊り部2bが形成されている。また、袋体2の上部の略中央部には注入口2aが形成されており、この注入口2aにおいて袋体2に後述の連通材4が接続されている。   The bag body 2 is formed of a water-permeable tubular woven fabric 10 (fabric) having both ends closed by sewing, and is formed in a shape that is long in the tube length direction (left-right direction in FIG. 2). The tubular woven fabric 10 is a seamless tubular woven fabric composed of a plurality of parallel warps and wefts woven continuously in a spiral shape with respect to these warps. Therefore, the bag body 2 has a high breaking pressure, and the bag body 2 can be easily broken even when mud is pressurized and inflated into the bag body 2 by an injection means such as a pump as will be described later. do not do. Further, when the mud is filled in the bag body 2 (see FIG. 5), the bag body 2 expands in the short direction (radial direction) and thereby contracts in the longitudinal direction (cylinder length direction). . As shown in FIGS. 1 and 2, one end of the tubular fabric 10 constituting the bag body 2 is sewn in a folded state, and a rod-like lifting tool 20 is inserted into this end. A cylindrical suspension 2b is formed. Further, an injection port 2a is formed at a substantially central portion of the upper portion of the bag body 2, and a communication material 4 described later is connected to the bag body 2 at the injection port 2a.

筒状排水材3は筒状に丸められた不織布からなり、図2に示すように、膨張状態の袋体2内において、その内部空間の中心付近を通って袋体2の長手方向(図2の左右方向)に延びるように配設されている。この筒状排水材3の長さは、泥土が充填された膨張状態の袋体2の長手方向の長さに略等しくなっており、筒状排水材3の両端部は、夫々、閉塞された状態で袋体2の両端部の内面に縫製等により固定されている。従って、袋体2内に泥土が充填されて、袋体2が短手方向に膨張するとともに長手方向に収縮したときには、その内部の筒状排水材3は袋体2の長手方向に直線的に張った状態となる(図5参照)。また、筒状排水材3の一端部(図2における左端部)には、次述の連通材4の端部が挿入されるスリット3aが形成されている。一方、筒状排水材3の他端部(図2における右端部)には、袋体2内へ開口するスリット3b(開口部)が形成されている。   The cylindrical drainage material 3 is made of a non-woven fabric rolled into a cylindrical shape. As shown in FIG. 2, the longitudinal direction of the bag body 2 passes through the vicinity of the center of the inner space in the inflated bag body 2 (FIG. 2). In the left-right direction). The length of the cylindrical drainage material 3 is substantially equal to the length in the longitudinal direction of the inflated bag body 2 filled with mud, and both end portions of the cylindrical drainage material 3 are closed. In the state, it is fixed to the inner surfaces of both end portions of the bag body 2 by sewing or the like. Therefore, when the mud is filled in the bag body 2 and the bag body 2 expands in the lateral direction and contracts in the longitudinal direction, the tubular drainage material 3 inside thereof is linear in the longitudinal direction of the bag body 2. It becomes a stretched state (see FIG. 5). Moreover, the slit 3a in which the edge part of the following communicating material 4 is inserted is formed in the one end part (left end part in FIG. 2) of the cylindrical drainage material 3. As shown in FIG. On the other hand, a slit 3 b (opening) that opens into the bag body 2 is formed at the other end (right end in FIG. 2) of the cylindrical drainage material 3.

図2、図3に示すように、筒状の連通材4は、小径部11aとこの小径部11aから径が拡大しながら延びる径拡大部11bとを有する、異径筒状織物11からなる。そして、この連通材4は、その径拡大部11bにおいて袋体2の注入口2aに縫製により接続されている。このように、連通材4は、径拡大部11bにおいて袋体2の注入口2aに接続されているため、この連通材4と袋体2との接続状態が自然なものとなり、後述のように、袋体2内に泥土30が注入されて袋体2が膨張するときに、袋体2が局所的に膨張することがない。   As shown in FIGS. 2 and 3, the tubular communication member 4 is formed of a different-diameter tubular woven fabric 11 having a small-diameter portion 11 a and a diameter-enlarged portion 11 b that extends from the small-diameter portion 11 a while expanding in diameter. And this communication material 4 is connected to the inlet 2a of the bag body 2 by sewing in the diameter expansion part 11b. Thus, since the communication material 4 is connected to the inlet 2a of the bag body 2 at the enlarged diameter portion 11b, the connection state between the communication material 4 and the bag body 2 becomes natural, and will be described later. When the mud 30 is injected into the bag body 2 and the bag body 2 expands, the bag body 2 does not expand locally.

一方、小径部11aは、内側に折り返されて袋体2の内部に入り込んでいる。そして、小径部11aが折り返されて形成された折り返し部4aは、袋体2の注入口2aから上方へ突出しており、この折り返し部4aには泥土注入用の注入ホース21(図4参照)が挿入される。また、小径部11aの端部は、スリット3aから筒状排水材3の一端部(図2の左端部)内に挿入されている。さらに、図2、図3に示すように、筒状排水材3内に入り込んだ小径部11aの端部にはスリット4bが形成されており、このスリット4bを介して連通材4と筒状排水材3とが連通している。また、小径部11aの先端部は、袋体2を形成する筒状織物10の、吊り部2bと反対側の端部と一緒に縫製されて、先端が閉塞された状態で固定されている。そして、この連通材4を介して袋体2の注入口2aと筒状排水材3の内部とが連通した状態となっている。   On the other hand, the small diameter portion 11 a is folded inward and enters the bag body 2. The folded portion 4a formed by folding the small diameter portion 11a protrudes upward from the injection port 2a of the bag body 2, and an injection hose 21 for mud injection (see FIG. 4) is provided in the folded portion 4a. Inserted. Moreover, the edge part of the small diameter part 11a is inserted in the one end part (left end part of FIG. 2) of the cylindrical drainage material 3 from the slit 3a. Further, as shown in FIGS. 2 and 3, a slit 4b is formed at the end of the small diameter portion 11a that has entered the cylindrical drainage material 3, and the communication material 4 and the cylindrical drainage are connected via the slit 4b. The material 3 communicates. Moreover, the front-end | tip part of the small diameter part 11a is sewn together with the edge part on the opposite side to the suspension part 2b of the cylindrical fabric 10 which forms the bag body 2, and is fixed in the state by which the front-end | tip was obstruct | occluded. Then, the inlet 2 a of the bag body 2 and the inside of the tubular drainage material 3 are in communication with each other through the communication material 4.

次に、この脱水用袋1を用いた高含水比の泥土30の袋詰め脱水処理について説明する。
まず、図4に示すように、折り返し部4aの内部に注入ホース21を挿入し、この注入ホース21から袋体2内に泥土30を注入していく。ここで、泥土30が注入されて袋体2が膨張したときに、注入ホース21が押し上げられることがないように、注入ホース21により袋体2を少し吊り上げて、袋体2の内部に空間が生じている状態で泥土30を注入することが好ましい。
Next, the bagging and dewatering treatment of the high moisture content mud 30 using the dewatering bag 1 will be described.
First, as shown in FIG. 4, the injection hose 21 is inserted into the folded portion 4 a and the mud 30 is injected into the bag body 2 from the injection hose 21. Here, when the mud 30 is injected and the bag body 2 expands, the bag body 2 is slightly lifted by the injection hose 21 so that the injection hose 21 is not pushed up, and there is a space inside the bag body 2. It is preferable to inject the mud 30 in the generated state.

このとき、図4に示すように、注入ホース21から注入された泥土30は、連通材4を通ってスリット4bから筒状排水材3の一端部(図2の左端部)内に流入する。さらに、この泥土30は、筒状排水材3内を通って他端部(図2の右端部)に形成されたスリット3aから袋体2内へ流れ込み、袋体2の内部に泥土30が堆積していく。そして、泥土30は袋体2の下部から徐々に充填され、注入圧力により袋体2はその短手方向(径方向)に膨張するとともに、長手方向(筒長方向)に収縮する。   At this time, as shown in FIG. 4, the mud 30 injected from the injection hose 21 flows into the one end portion (the left end portion in FIG. 2) of the cylindrical drainage material 3 from the slit 4 b through the communication material 4. Further, the mud 30 flows into the bag body 2 from the slit 3 a formed at the other end (the right end in FIG. 2) through the cylindrical drainage material 3, and the mud 30 accumulates inside the bag body 2. I will do it. And the mud 30 is gradually filled from the lower part of the bag body 2, and the bag body 2 expands in the short side direction (radial direction) by the injection pressure and contracts in the longitudinal direction (cylinder length direction).

このように、注入された泥土は袋体2の内面に直接注入されず、連通材4の内部及び不織布からなる筒状排水材3の内部を経由して袋体2の中に充填されていく。そのため、注入された泥土の流れに乱れが発生せず、袋体2の内面に形成された泥膜が破壊されることがないので、特に注入初期において袋体2から排出される水の濁り(初期濁り)を効果的に抑えることができ、環境汚染物質を含有するような泥土の脱水にも有効である。また、注入された泥土30は、筒状排水材3内を通過する間に濾過されるので、これによっても濁りが除去される。   Thus, the injected mud is not directly injected into the inner surface of the bag body 2, but is filled into the bag body 2 via the inside of the communication material 4 and the inside of the cylindrical drainage material 3 made of nonwoven fabric. . Therefore, the flow of the injected mud is not disturbed, and the mud film formed on the inner surface of the bag body 2 is not destroyed. (Early turbidity) can be effectively suppressed, and it is also effective for dewatering mud containing environmental pollutants. Moreover, since the injected mud 30 is filtered while passing through the cylindrical drainage material 3, turbidity is also removed by this.

この泥土30の注入中、筒状排水材3の内部に泥土30が充填されて、筒状排水材3が膨張していく。ここで、前述したように、筒状排水材3の長さは、泥土30が充填されて径方向に膨張した状態での、袋体2の長手方向長さに略等しい。そのため、筒状排水材3の内部に泥土30が充填されていくと、図5に示すように、筒状排水材3は、袋体2の長手方向に張った状態で筒状に保持され、袋体2の内面に押しつけられたり、周囲の泥土30に押し潰されることがない。   During the pouring of the mud 30, the mud 30 is filled in the cylindrical drainage material 3, and the cylindrical drainage material 3 expands. Here, as described above, the length of the cylindrical drainage material 3 is substantially equal to the length in the longitudinal direction of the bag body 2 in a state where the mud 30 is filled and expanded in the radial direction. Therefore, when the mud 30 is filled into the cylindrical drainage material 3, as shown in FIG. 5, the cylindrical drainage material 3 is held in a cylindrical shape in a state stretched in the longitudinal direction of the bag body 2, It is not pressed against the inner surface of the bag 2 or crushed by the surrounding mud 30.

さらに、袋体2内に泥土30を注入していくと、図5に示すように、袋体2の上部まで堆積してきた泥土30が、折り返し部4a及び袋体2の内部に入り込んだ小径部11aの一方側(図5における小径部11aの右側の空間)に集中して充填される。すると、袋体2内に入り込んだ小径部11aがこの泥土30により圧迫されて袋体2の内面に押しつけられ、小径部11aが閉塞される。従って、泥土30が袋体2内に充填された後に、連通材4の折り返し部4aから外部へ泥土30が逆流しないようになる。尚、泥土30を袋体2内に充填した後に、袋体2を圧縮しながら、注入ホース21側から連通材4の内部を減圧することにより、小径部11aをその周囲の泥土30によりさらに確実に押し潰して完全に閉塞することが好ましい。   Further, when the mud 30 is poured into the bag body 2, the mud 30 deposited up to the upper part of the bag body 2 is turned into the folded portion 4 a and the small diameter portion into the bag body 2 as shown in FIG. 5. Filling is concentrated on one side of 11a (the space on the right side of the small diameter portion 11a in FIG. 5). Then, the small diameter part 11a that has entered the bag body 2 is pressed by the mud 30 and pressed against the inner surface of the bag body 2, and the small diameter part 11a is closed. Therefore, after the mud 30 is filled in the bag body 2, the mud 30 does not flow backward from the folded portion 4 a of the communication material 4 to the outside. In addition, after filling the mud 30 into the bag body 2, the inside of the communication material 4 is decompressed from the injection hose 21 side while compressing the bag body 2, so that the small-diameter portion 11 a is more reliably secured by the surrounding mud 30. It is preferable to crush it to completely close it.

このようにして袋体2内に泥土30を充填した後に、その泥土30を脱水するために、脱水用袋1を一定期間放置する。ここで、袋体2内の泥土30は、袋体2の表面から離れた中心付近に位置している部分ほど、その水分が袋体2の表面まで移動しにくく、外部へ排出されにくいため、脱水に時間がかかる。しかし、本実施形態の脱水用袋1においては、図5に示すように、泥土30が充填された膨張状態の袋体2内には、その内部空間の中心付近を横切る筒状排水材3が袋体2の長手方向に延びた状態で配設されている。そのため、袋体2内の中心付近に位置する泥土30の水分は筒状排水材3を伝って袋体2の表面まで速やかに移動し、外部へ排出される。この場合には、泥土中の水分が短時間で袋体2の表面へ移動して外部へ排出されるため、脱水時間が短縮される。また、膨張した袋体2内の泥土には高い注入圧力が作用しているため、袋体2が放置されたときの泥土からの脱水が促進される。   After the mud 30 is filled in the bag body 2 in this manner, the dewatering bag 1 is left for a certain period in order to dehydrate the mud 30. Here, since the mud 30 in the bag body 2 is located near the center away from the surface of the bag body 2, its moisture is less likely to move to the surface of the bag body 2 and is not easily discharged to the outside. Dehydration takes time. However, in the dewatering bag 1 of the present embodiment, as shown in FIG. 5, the tubular drainage material 3 that crosses the vicinity of the center of the inner space is placed in the inflated bag body 2 filled with the mud 30. The bag body 2 is disposed so as to extend in the longitudinal direction. Therefore, the moisture of the mud 30 located near the center in the bag body 2 quickly moves to the surface of the bag body 2 through the cylindrical drainage material 3 and is discharged to the outside. In this case, since the water in the mud moves to the surface of the bag body 2 in a short time and is discharged to the outside, the dehydration time is shortened. Moreover, since the high injection | pouring pressure is acting on the mud in the expanded bag body 2, the dehydration from the mud when the bag body 2 is left is promoted.

また、前述したように、泥土30の注入中に筒状排水材3内にも泥土30が充填されて、筒状排水材3は、泥土30に押し潰されることなく、袋体2内でその長手方向に張った状態で筒状に保持されるので、筒状排水材3が袋体2の内面に押しつけられたりすることがない。そのため、袋体2内の泥土30に含まれる水分は、筒状排水材3を伝ってスムーズに袋体2の表面まで移動するため、脱水時間がさらに短縮される。   In addition, as described above, the mud 30 is also filled in the cylindrical drainage material 3 during the pouring of the mud 30, and the cylindrical drainage material 3 is not crushed by the mud 30, and the Since it is held in a cylindrical shape in a state stretched in the longitudinal direction, the cylindrical drainage material 3 is not pressed against the inner surface of the bag body 2. Therefore, the moisture contained in the mud 30 in the bag body 2 moves smoothly to the surface of the bag body 2 through the cylindrical drainage material 3, so that the dehydration time is further shortened.

さらに、本実施形態の脱水用袋1では、筒状排水材3は袋体2内の内部空間の中心付近を通ってその長手方向に延びている。この場合には、筒状排水材3が短手方向に延びている場合と比べて筒状排水材3の長さが長くなるため、袋体2内のより広い範囲の泥土30から筒状排水材3を伝って水分が表面へ排出されることになり、泥土30の脱水がさらに効率よく行われる。   Furthermore, in the dewatering bag 1 of the present embodiment, the cylindrical drainage material 3 extends in the longitudinal direction through the vicinity of the center of the internal space in the bag body 2. In this case, since the length of the cylindrical drainage material 3 becomes longer than the case where the cylindrical drainage material 3 extends in the short direction, the cylindrical drainage from the mud 30 in a wider range in the bag body 2. Moisture is discharged to the surface through the material 3, and the mud 30 is dehydrated more efficiently.

尚、図5に示すように、泥土30の脱水がほぼ完了した状態の脱水用袋1は、扁平な断面形状を有し、安定性がよいため、この脱水用袋1を土嚢などに利用することができる。この場合には、図1に示すように、脱水用袋1を、吊り部2bに挿通された吊り具20を介してクレーン等により引き上げることにより、所定の場所へ運搬することが可能である。   As shown in FIG. 5, the dewatering bag 1 in a state where the dewatering of the mud 30 has been almost completed has a flat cross-sectional shape and good stability. Therefore, the dewatering bag 1 is used as a sandbag or the like. be able to. In this case, as shown in FIG. 1, the dehydration bag 1 can be transported to a predetermined place by pulling it up with a crane or the like through the suspension tool 20 inserted through the suspension portion 2 b.

次に、本実施形態の脱水用袋1による効果を、具体的に検証した実施例について説明する。
本実施例においては、まず、袋体2として、直径1.0m、長さ2.5mで、ポリエステル繊維製の目付527g/m2、内容積1.3m3の筒状織物10からなるものを使用する。筒状織物10は、前述の通り円周方向に継ぎ目のない筒状織物であって、この筒状織物10からなる袋体2は、0.1MPaという高い耐圧力を有している。また、筒状排水材3としては、直径約50cm、厚さ2mm、長さ2.2mで、目付165g/m2の不織布を筒状に丸めたものを使用した。尚、この筒状排水材3の長さは、袋体2が膨張してその長さ方向に収縮したときの長さにほぼ一致している。さらに、連通材4としては、小径部11aの径が100mm、径拡大部11bの最大径が200mmのものを使用した。
Next, an example in which the effect of the dehydration bag 1 of the present embodiment is specifically verified will be described.
In this embodiment, first, the bag 2 is made of a tubular woven fabric 10 having a diameter of 1.0 m, a length of 2.5 m, a polyester fiber basis weight of 527 g / m 2 , and an internal volume of 1.3 m 3. use. As described above, the tubular fabric 10 is a seamless tubular fabric in the circumferential direction, and the bag body 2 made of the tubular fabric 10 has a high pressure resistance of 0.1 MPa. Further, as the cylindrical drainage material 3, a non-woven fabric having a diameter of about 50 cm, a thickness of 2 mm, a length of 2.2 m, and a basis weight of 165 g / m 2 was used. In addition, the length of this cylindrical drainage material 3 is substantially equal to the length when the bag body 2 expands and contracts in the length direction. Further, as the communication material 4, a material having a diameter of the small diameter portion 11a of 100 mm and a maximum diameter of the diameter enlarged portion 11b of 200 mm was used.

ここで、縫製により筒状に作製された既存の脱水用袋はその耐圧力が低いため、泥土注入時の破断を防ぐために、ポンプの注入圧力が袋体に作用しない範囲の高さまで(充填された泥土の自重による引張力のみが脱水用袋に作用している範囲内で)しか充填作業を行えない。例えば直径1.0mの袋体の場合、50cm程度の高さまでしか充填できない(充填量 約1.2m3)ことがわかっている。しかし、前述の袋体2は0.1MPaもの高い耐圧力を有しているため、注入圧0.03〜0.05MPaで泥土を注入したところ、直径1.0mの袋では、泥土が充填された直後の膨張状態で袋体2の高さが90cm程度(充填量 約1.3m3)に達していたが、袋体2には破断等の問題は全く見られなかった。このことから、既存の同一寸法の袋よりも1袋あたりの充填量を増やせる(本実施例では、約1割増し)ことが実証された。 Here, since the pressure resistance of the existing dewatering bag made into a cylindrical shape by sewing is low, in order to prevent breakage at the time of mud pouring, the pump is filled (filled up to a height that does not act on the bag body). Only when the tensile force due to the weight of the mud is acting on the dewatering bag). For example, in the case of a bag having a diameter of 1.0 m, it is known that the bag can only be filled up to a height of about 50 cm (filling amount is about 1.2 m 3 ). However, since the above-described bag body 2 has a pressure resistance as high as 0.1 MPa, when mud is injected at an injection pressure of 0.03 to 0.05 MPa, the bag with a diameter of 1.0 m is filled with mud. In the inflated state immediately after, the height of the bag body 2 reached about 90 cm (filling amount: about 1.3 m 3 ), but the bag body 2 did not show any problems such as breakage. From this, it was proved that the filling amount per bag can be increased as compared with the existing bags of the same size (in this embodiment, about 10% increase).

また、袋体2内に泥土を充填してから脱水が終了するまでの時間(袋体高さがほぼ一定となるまでの時間)を、筒状排水材3がない場合と筒状排水材3がある場合でそれぞれ測定して比較した結果を図6に示す。図6に示すように、筒状排水材3がない場合では、袋体2の高さがほぼ一定の高さ(約470mm程度)となるまでに約15日かかるのに対して、筒状排水材3がある場合では約5日しかかかっておらず、筒状排水材3を設けることにより、排水性能が格段に向上することが実証された。   Further, the time from when the mud soil is filled in the bag body 2 until the dehydration is completed (the time until the bag body height becomes substantially constant) is determined when the cylindrical drainage material 3 is not present and when the cylindrical drainage material 3 is FIG. 6 shows the results of measurement and comparison in some cases. As shown in FIG. 6, in the case where there is no cylindrical drainage material 3, it takes about 15 days for the bag 2 to reach a substantially constant height (about 470 mm), whereas the cylindrical drainage In the case where the material 3 is present, it takes only about 5 days, and it was proved that the drainage performance is remarkably improved by providing the cylindrical drainage material 3.

さらに、泥土の注入中において袋体2からの排出される排水の濁度を、筒状排水材3がない場合と筒状排水材3がある場合でそれぞれ測定して比較した結果を図7に示す。図7に示すように、筒状排水材3がある場合では、筒状排水材3がない場合に比べて、特に、充填開始から1時間経過するまでに排出される排水の濁度がかなり小さくなっている。このことから、筒状排水材3を設けることにより、排水の初期濁りを抑制する機能が向上することが実証された。   Furthermore, the turbidity of the drainage discharged from the bag 2 during the mud injection is measured and compared in the case where there is no cylindrical drainage material 3 and in the case where the cylindrical drainage material 3 is present, and FIG. Show. As shown in FIG. 7, in the case where the cylindrical drainage material 3 is present, the turbidity of the drainage discharged until 1 hour elapses from the start of filling is considerably smaller than the case where the cylindrical drainage material 3 is not present. It has become. From this, it was demonstrated that the function of suppressing the initial turbidity of the drainage is improved by providing the cylindrical drainage material 3.

次に、前記実施形態に種々の変更を加えた変更形態について説明する。但し、前記実施形態と同様の構成を有するものについては、同じ符号を付して適宜その説明を省略する。
1]前記実施形態の脱水用袋1においては、連通材4の一端部(小径部11a)が袋体2内に折り返されているが、図8に示す脱水用袋31のように、連通材34が、折り返されることなく袋体2の注入口2aに接続されていてもよい。この場合でも、袋体2内に入り込んだ連通材34の部分は袋体2内の泥土により圧迫されるため、袋体2からの泥土の逆流はある程度防止される。
Next, modified embodiments in which various modifications are made to the embodiment will be described. However, components having the same configuration as in the above embodiment are given the same reference numerals and description thereof is omitted as appropriate.
1] In the dehydrating bag 1 of the above-described embodiment, one end portion (small-diameter portion 11a) of the communication member 4 is folded back into the bag body 2. However, like the dehydrating bag 31 shown in FIG. 34 may be connected to the inlet 2a of the bag body 2 without being folded back. Even in this case, since the portion of the communication material 34 that has entered the bag body 2 is pressed by the mud in the bag body 2, the backflow of the mud from the bag body 2 is prevented to some extent.

2]連通材の端部が筒状排水材3の内部に挿入されている必要は必ずしもなく、図9に示す脱水用袋41のように、連通材44が、穴3aを介して筒状排水材3の内部に連通した状態で、筒状排水材3に縫製等により直接接続されていてもよい。   2] It is not always necessary that the end of the communication material is inserted into the cylindrical drainage material 3, and the communication material 44 is connected to the cylindrical drainage via the hole 3a as in the dewatering bag 41 shown in FIG. You may connect directly to the cylindrical drainage material 3 by sewing etc. in the state connected to the inside of the material 3. FIG.

3]筒状排水材と、連通材や袋体の内部を連通させる連通部は、前記実施形態のスリット3a,3b(図2参照)で構成されている必要は必ずしもなく、例えば、スリットよりも大きく開口した略円形状の穴であってもよい。この場合には、連通材4から筒状排水材3を介して袋体2内へ泥土を注入しやすくなる。   3] The tubular drainage material and the communication part that communicates the inside of the communication material or the bag body do not necessarily need to be configured by the slits 3a and 3b (see FIG. 2) of the above-described embodiment. It may be a substantially circular hole with a large opening. In this case, it becomes easy to inject mud into the bag body 2 from the communication material 4 through the tubular drainage material 3.

4]筒状排水材3は、袋体2内でその長手方向に延びている必要は必ずしもなく、例えば、短手方向に延びていてもよいし、あるいは、袋体2内を斜めに横切るように延びていてもよい。但し、袋体2の表面から離れた位置にあるほど泥土は脱水されにくいため、筒状排水材3は、泥土が充填された膨張状態の袋体2内において、その内部空間の中心付近を通るように配設されていることが好ましい。   4] The cylindrical drainage material 3 does not necessarily have to extend in the longitudinal direction in the bag body 2, for example, may extend in the lateral direction, or may cross the bag body 2 obliquely. It may extend to. However, since the mud is less likely to be dehydrated the further away from the surface of the bag body 2, the cylindrical drainage material 3 passes through the vicinity of the center of the internal space in the inflated bag body 2 filled with mud. It is preferable that they are arranged as described above.
