Description

  The present invention relates to a landfill production apparatus for producing a landfill for continuously mixing an anti-separation agent into a soil mixture and dropping it into water.

  Generally, when constructing artificial islands in rivers, lakes, and marine areas, earth and sand are thrown into land surrounded by steel sheet piles, steel pipe sheet piles, concrete walls, and the like. Since the property of the earth and sand used for such landfill influences the difficulty of construction and the quality after completion, it is preferable to use uniform earth and sand. For this reason, soil improvement materials (stabilizers, separation prevention materials, etc.) are mixed in advance with earth and sand to make landfill and embankment. Various types of mixers are used for the production of landfills and embankments made of this mixed material, such as drum-type continuous mixers for improved structural soils such as roadbeds. In addition, it is not suitable for large amounts of continuous mixing in terms of price, labor saving, automation, etc.

  Therefore, the present applicant has previously proposed a method for continuously mixing earth and sand and a soil improvement material and a plant for carrying out this method (see Patent Document 1). As described above, since the properties of earth and sand affect the difficulty of construction and the quality after completion, a method for more easily and uniformly mixing earth and sand with a soil quality improving material is required.

The earth and sand hopper 21 is provided with a discharge port 24 on a side surface, and an opening is provided at the bottom of the earth and sand hopper 21. The belt feeder 22 is disposed so as to receive the earth and sand through the opening and convey the earth and sand to the outside through the discharge port 24. The terminal portion of the belt feeder 22 is located above the starting end portion of the first belt conveyor 10, and the earth and sand conveyed by the belt feeder 22 falls from the terminal portion and is supplied to the starting end portion of the first belt conveyor 10.

Further, cement is supplied to the table feeder 33 from the cement hopper 32. The table feeder 33 discharges the cement to the outside so that the discharge amount per unit time is constant.

  In this embodiment, the table feeder 33 is used to supply a predetermined amount of cement. However, the present invention is not limited to this. For example, a screw feeder, a rotary feeder, or the like that can supply a predetermined amount of cement based on a set value may be used.

More specifically, the housing 41 is provided with a supply port 42 as an opening in the upper portion, and receives earth and sand and cement dropped from the terminal portion of the first belt conveyor 10 through the supply port 42. ing. A rotation shaft 44 is rotatably provided in the housing 41. A plurality of chains 45 are attached to the rotation shaft 44.

  When the rotation shaft 44 rotates, the chain 45 also rotates around the rotation shaft 44. In this state, when earth and sand and cement are supplied from the supply port 42, the earth and sand and cement are crushed and mixed by the chain 45 while falling in the housing 41. Hereinafter, the earth and sand mixed by the mixing device 40 are referred to as an earth and sand mixture. The earth and sand mixture is discharged from the mixing device 40 onto the second belt conveyor 50 disposed below the mixing device 40.

  In the present embodiment, the mixing device is crushed and mixed by the chain 45 that rotates at high speed.

  The 2nd belt conveyor 50 is arrange | positioned so that the earth and sand mixture discharged | emitted from the mixing apparatus 40 may be conveyed to a predetermined place. Further, two nozzle sprays 60 which are an example of spraying means for spraying the anti-separation agent solution to the earth and sand mixture falling from the terminal part are disposed below the terminal part of the second belt conveyor 50.

Each nozzle spray 60 is arrange | positioned at the both sides which oppose so that the earth-and-sand mixture which falls may be pinched | interposed, and it sprays the anti-separation agent solution from both sides of the earth-and-sand mixture. Thereby, the earth and sand mixture and the separation inhibitor solution are mixed almost uniformly.

  In the separation inhibitor dissolving liquid sprayed from the nozzle spray 60, a separation inhibitor having a predetermined ratio is dissolved with respect to the dry weight of the earth and sand contained in the earth and sand mixture. Thereby, a landfill material in which earth and sand, cement, and an antiseparation agent are mixed at a predetermined ratio is formed by spraying the separation inhibitor solution onto the earth and sand mixture falling from the second belt conveyor 50.

  Here, the separation preventing agent is a water-soluble polymer material that prevents separation of earth and sand and cement in water, and examples thereof include cellulose-based and acrylic-based water-soluble polymers. The separation inhibitor solution is formed as follows.

  FIG. 3 is a schematic configuration diagram of the landfill material manufacturing apparatus according to the present embodiment.

  As shown in the figure, the seawater tank 80 stores seawater pumped by a water pumping pump 81. Further, the separation preventing agent powder feeder 82 stores a powdered separation preventing agent.

  Seawater is supplied to the separation inhibitor dissolving tank 83 from the seawater tank 80 through the feed pump 84, and the separation inhibitor is supplied from the separation inhibitor powder feeder 82. Thereby, the separation inhibitor is dissolved in seawater to form a separation inhibitor solution. The separation inhibitor dissolving tank 83 is provided with a stirrer 85, and the stirrer 85 promotes the dissolution of the separation inhibitor into seawater by stirring. The anti-separation agent solution formed in the anti-separation agent dissolving tank 83 is supplied to the anti-separation agent solution storage tank 87 via the anti-separation agent solution pump 86.

  The anti-separation agent solution storage tank 87 and the nozzle spray 60 are connected via a metering pump 88, and the anti-separation agent solution stored in the anti-separation agent solution storage tank 87 is brought to a predetermined pressure by the metering pump 88.

Similarly, the separation inhibitor dissolution tank 83 is supplied with seawater from the seawater tank 80 and separated from the separation inhibitor powder feeder 82 so that the amount of the separation inhibitor solution stored therein is constant. An inhibitor is supplied.

  In this embodiment, seawater is used as a solvent for the separation inhibitor solution, but water may be used.

  A series of operations of the above-described landfill material manufacturing apparatus will be briefly described. The first belt conveyor 10 is supplied with earth and sand from the earth and sand feeder device 20 and supplied with cement from the cement supply device 30. These earth and sand and cement are conveyed to the mixing device 40 by the first belt conveyor 10. And in the mixing apparatus 40, the earth and sand mixture is formed from earth and sand and cement. When the earth and sand mixture falls from the second belt conveyor 50, the separation inhibitor solution is sprayed from the nozzle spray 60, whereby the earth and sand mixture and the separation agent solution are mixed to form a landfill material.

  A part of the landfill production apparatus will be described in detail with reference to FIG. This figure is a schematic configuration diagram of a part of the landfill production apparatus of the present embodiment. As shown in FIG. 4, a regulating blade 51 that regulates the conveyed earth and sand mixture to a predetermined height is provided in the vicinity of the conveying surface of the second belt conveyor 50. The amount of the earth and sand mixture falling from the end of the belt conveyor 50 is kept constant by the regulation blade 51.

  Two nozzle sprays 60 (60 </ b> A, 60 </ b> B) are provided below the terminal end of the second belt conveyor 50 to inject the separation inhibitor solution into the earth and sand mixture falling from the second belt conveyor 50. The nozzle spray 60A and the nozzle spray 60B are arranged so as to sandwich the falling earth and sand mixture from both sides and be equidistant from each falling earth and sand mixture, that is, so as to face each other around the falling earth and sand mixture. Has been. These nozzle sprays 60 can spray the anti-separation agent solution from both sides of the earth and sand mixture, and mix the earth and sand mixture and the anti-separation agent solution almost uniformly. In addition, each nozzle spray 60 is provided in the position close | similar to the earth-and-sand mixture which falls, so that the force (henceforth contact pressure of an anti-separation-agent solution) which a separation-preventing agent solution collides with a sediment mixture may not fall.

  In addition, each nozzle spray 60 is configured to inject the separation inhibitor solution from a direction orthogonal to the falling direction of the earth and sand mixture.

  The shape of the separation inhibitor dissolving liquid sprayed from the nozzle spray 60 is preferably a shape that hardly spreads in the vertical direction, and particularly preferably a film shape that spreads in the horizontal direction. Since the spray pressure is not dispersed in the vertical direction, it can be concentrated in the horizontal direction, and the separation inhibitor solution can sufficiently enter the center of the falling earth and sand mixture.

  Here, determination of the injection state of the separation inhibitor solution taking into account the cross-sectional shape when the earth and sand mixture is dropped will be described.

  The cross-sectional shape of the earth and sand mixture at the time of dropping in the present invention refers to the horizontal cross-sectional shape at the time of dropping, and the size of the cross-section is also taken into consideration. And the determination of the spray state of the separation inhibitor solution is to select the type, number, and arrangement of the nozzle spray 60 in consideration of the cross-sectional shape when the earth and sand mixture falls, the spray pressure of the separation inhibitor solution, The control is to adjust the flow rate distribution in the width direction of the separation inhibitor solution, the injection width of the separation inhibitor solution, and the concentration of the separation inhibitor solution. The spray pressure of the separation inhibitor solution is a pressure when the separation agent solution flows into the nozzle spray 60. Further, the flow rate distribution in the width direction of the separation inhibitor solution is a horizontal flow distribution of the separation solution when contacting the falling earth and sand mixture. Is the width at which the anti-separation agent solution comes into contact with the falling earth and sand mixture.

  First, the nozzle spray 60 selects a kind, a number, and arrangement | positioning suitably considering the magnitude | size of the cross section of the earth-and-sand mixture which falls. In the present embodiment, since the height of the earth and sand mixture on the second belt conveyor 50 is restricted using the restriction blade 51, the cross-sectional shape of the falling earth and sand mixture is rectangular. . As shown in FIG. 5, in the case of a relatively small rectangular shape, the two nozzle sprays 60A and the nozzle spray 60B may be provided so as to face each other as described above. At this time, since the cross-sectional shape of the earth and sand mixture is rectangular, the nozzle spray 60A and the nozzle spray 60B have substantially uniform contact pressure in the width direction of the separation inhibitor solution, and the width direction of the separation solution. Select a uniform flow rate distribution. Moreover, as shown in FIG. 6, when the cross-sectional shape of the falling earth-and-sand mixture is a comparatively small ellipse, what is necessary is just to provide the two nozzle sprays 60C and the nozzle spray 60D so as to oppose each other. At this time, a nozzle spray is selected in which the spray pressure at the center portion in the width direction of the separation inhibitor solution is strong and the spray amount at the center portion in the width direction of the separation solution is increased. Although not shown, when the width of the cross-sectional shape of the falling earth and sand mixture is large, it is preferable to use a large number of nozzle sprays. At this time, the number of nozzle sprays is an even number, and the nozzle sprays are arranged so as to face each other centering on the falling earth and sand mixture. Moreover, each nozzle spray is arrange | positioned so that it may be in the state which mutually injects a little so that there may be no injection leakage in the width direction of a cross-sectional shape.

  And it sets so that the injection width | variety of a separation inhibitor solution may become more than the maximum width of the cross-sectional shape of the earth-and-sand mixture which falls. As shown in FIGS. 5 and 6, when two opposing nozzle sprays are used, the spray width of the anti-separation agent solution in each nozzle spray is equal to or greater than the maximum width of the cross-sectional shape of the falling earth and sand mixture. To. When a large number of nozzle sprays are used, the distance between the end portions in the width direction of the spray of the nozzle spray is set to be equal to or greater than the maximum width of the cross-sectional shape of the falling soil mixture. In addition, the spread of the anti-separation agent solution sprayed from each nozzle spray 60 in the cross-sectional direction, that is, the spray angle of the anti-separation agent solution is not particularly limited, but is preferably 60 to 90 °, for example. This is because if the spray angle becomes too small, it is necessary to narrow the fall width of the earth and sand mixture to reduce the throughput per unit time or to use many nozzle sprays. On the other hand, if the spray angle becomes too large, the contact pressure of the separation inhibitor solution cannot be sufficiently secured at the end in the width direction of the cross-sectional shape, and the thickness direction of the earth and sand mixture (the direction perpendicular to the width direction) This is because the anti-separation agent solution may not reach the center.

  The injection pressure of the separation inhibitor solution is generally proportional to the injection amount, but is set so that the separation inhibitor solution sufficiently reaches the center of the cross-sectional shape. That is, the injection pressure is adjusted in consideration of not only the amount of the earth / sand mixture dropped per unit time but also the cross-sectional shape of the earth / sand mixture. For example, even when the amount of the earth / sand mixture dropped per unit time is the same, if the cross-sectional shape of the earth / sand mixture spreads in the thickness direction (direction perpendicular to the width direction), the injection pressure is set high. Thereby, the separation inhibitor solution can reach the inside in the thickness direction of the central portion in the width direction of the earth and sand mixture. Further, when a large number of nozzle sprays are used, the spray pressures of the nozzle sprays may be the same or different. When the cross-sectional shape of the earth and sand mixture is rectangular, the spray pressure of each nozzle spray should be the same. When the cross-sectional shape of the earth and sand mixture is elliptical, the end in the width direction What is necessary is just to make the injection pressure of the nozzle spray arrange | positioned in the center part of the width direction larger than the injection pressure of the nozzle spray arrange | positioned in this.

  As described above, when the injection pressure and flow rate distribution of the separation inhibitor solution are determined in consideration of the cross-sectional shape of the earth and sand mixture, the injection amount of the separation inhibitor solution per unit time is determined. On the other hand, the mixing ratio of the earth and sand mixture and the separation inhibitor solution is set to a predetermined ratio within a range of, for example, a weight ratio of 20: 1 to 10: 1. In this way, the concentration of the anti-separation agent solution is determined in consideration of the injection amount of the anti-separation agent solution per unit time, the falling amount of the earth and sand mixture per unit time, and the mixing ratio of the anti-separation agent and the earth and sand mixture. To do. For example, when the injection pressure of the separation inhibitor solution is increased and the injection amount of the separation inhibitor solution per unit time is increased, the concentration of the separation inhibitor solution is set low.

  As described above, by determining the injection state of the separation inhibitor dissolving liquid in consideration of the cross-sectional shape at the time of dropping, the earth and sand mixture and the separation inhibitor can be uniformly mixed at a predetermined mixing ratio.

  By using the landfill production apparatus of this embodiment, a large amount of landfill can be obtained in which the earth and sand mixture and the separation inhibitor are uniformly mixed.

  In addition, in this embodiment, although the fall state of the earth and sand mixture was regulated using the regulation blade 51, the regulation means of the fall state of the earth and sand mixture is not limited to this. For example, by providing a restriction plate at the upper end of the second belt conveyor 50, or by providing a hollow cylindrical body or rectangular parallelepiped restriction device at the upper end of the second belt conveyor 50, the falling state of the sediment mixture can be reduced. It may be regulated. In addition, the fall state of the earth and sand mixture does not necessarily need to be regulated. In this case, for example, the amount of the earth and sand mixture discharged from the mixing device is adjusted to be constant.
