DRAIN FORMING EQUIPMENT FOR REINFORCING SOFT
GROUND, AND METHOD AND STRUCTURE FOR
ARRANGING DRAINS
TECHNICAL FIELD
The présent invention relates to a technology of reinforcing softgrounds, and more particularly to a pack for molding a sand pile to form adrain, a pack guide casing for driving a pack underground, a pack filedriving apparatus which is used for driving a pack into a guide casing, anda drain structure and an alignment method thereof.
BACKGROUND ART A vertical draining method such as a flexible sand drain and/or apaper drain is generally used for reinforcing a soft ground. A conventionalvertical draining method drives a cylindrical guide casing underground,inserts a sand pack or a paper drain board into the guide casing, and then 10 removes the guide casing. FIG. 1 is a perspective view of a flexible sandpack and a guide casing which are used for a conventional vertical drainingmethod. As shown in FIG. 1, the conventional vertical draining method isaccomplished by burying a cylindrical guide casing 10 underground, andthen inserting a sand pile molding pack 20 into guide casing 10. The pack 15 20, which comprises a mesh-type texture, is formed by overlapping two sheets of the mesh-type textures such that side portions of these sheets form reinforcement portions 31 and 32 extending lengthwise by-connecting both ends or thermally melting them to attach to each other. Pack 20 010524 inscrted into guide casing 10 is filled with sand. and then guide casing 10 isremoved at the sand-filled State to form a drain.
However, the conventional sand pile molding pack has problems that.the manufacturing method is complicated and the manufacturing cost ishigh. Also, the conventional molding packs are susceptible to breakage orcut-off, or some discrepancy between latitude and longitude. Further, theconventional pack has a problem that the reinforcement portion 31 or 32 isfolded, such that a fine soil cannot pass, and a film is formed which lowersa draining effect. Also, since the conventional flexible drain is in acylindrical shape and the diameter of the drain is limited to a range within25cm, a draining contact area is small which lowers a draining effect.
The conventional guide casing is formed as only a cylindrical shape, toaccordingly rai se a phenomenon of twisting the pack when the pack i sinserted. Moreover, since the paper drain board is a structure of a thinplate when the paper drain is formed, many spac.es are formed therein.Thus, removal of the casing causes an excessive ground movement.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinbelow, preferred embodiments of the présent invention will bedescribed in detail with reference to the accompanying drawings. 7 010524 FIGs. 2A through 2C are views explaining a sand pile molding packaccording to one embodiment of the présent invention. The pack of theprésent invention is fabricated by a métal injection molding method. FIG.2A shows a sand pile molding pack material 50 having a reinforcementportion 51 at a constant interval which is obtained by the injection molding.A sand pile molding pack 60 shown in FIG. 2B is obtained by cutting packmaterial 50 of FIG. 2A to include at least one reinforcement portion 51 andcombining the eut pack materials with each other. FIG. 2C is a cross-sectional view of a reinforcement portion of a sandpile molding pack according to another embodiment of the présent invention.The reinforcement portion 51 in this embodiment includes an electricconductor 53 therein, which is for connecting an electrode when applying anelectric osmotic method thereto. One electric conductor can be installed for every reinforcement portion 51 of pack 60, or a plurality of conductors canbe separately installed in a single reinforcement portion. FIGs. 3A through 3F are plan views of sand pile molding packsaccording to yet another embodiments of the présent invention. It can beseen that the packs of the présent embodiments are extended lengthwise inthe same pattern despite no showing perspective views. FIGs. 3A and 3C show rectangular packs and FIGs. 3D and 3F showcylindrical packs. In these embodiments, the pack includes net portions 71and a plurality of reinforcement portions 72. The reinforcement portion 72can be attached to a sub-texture, and then the reinforcement portion 72attachcd to the sub-texture is formed to hâve a bending portion for drain.Thus, the packs according to these embodiments hâve a merit that a 8 010524 flexible sand drain and a paper drain can be simultaneously formed.
Further, since the pack is in a rectangular shape, a draining area is30% greater than a cylindrical pack which consumes the same amount ofsand as that of the rectangular pack. That is. the rectangular pack hascircumferential length of more than 30% at the same area compared withthe cylindrical pack. Thus. an increased draining effect of more than 30%can be obtained, even though the same amount of sand is used.
Furthermore, the conventional flexible pack is continuously producedwithout any marking in the same shape and color, and then i$ measuredand eut by necessary lengths in use. The drain which is constructed byusing such a pack has an exposed portion of the same shape and color.Thus. to ascertain whether the underground drain has been constructed upto a target depth, construction drawings or records should be checked or itshûuld be measured using other equipment.
Thus, the pack of the présent invention has markings which canidentify the length of the pack. That is, when the pack is produced,various colors or figures are marked on the pack. Alternatively,reinforcement portions having the identified patterns are made and attachedto the pack to advantageously permit the identification of the length byhuman vision. Thus, after construction, identification of the markings of theexposed drain can make a judgement of whether such a construction wasproperly done. Accordingly, poor construction can be prevented, and easyconstruction, or effective construction control can be performed. FIGs. 4 A and 4B are perspective view s of a drain according toembodiments of the présent invention. The drain of the présent invention 010524 includes at least one or more reinforcement members 82 for drainingaccélération at the inside of the sand drain 81. A drain board or a suctionfiber of water can be used as a reinforcement member 82 for drainingaccélération. Thus, This drain can expedite highly drain efficiency andmaintain a certain operation for a long-term time, compared with theconventional paper drain or sand drain. FIGs. 5A and 5B are perspective views of a weighl material which isused for dropping a reinforcement member for draining accélération whenforming a drain. The weight material is fabricated with a rigid materialsuch as concrète, each of which forms a certain number of connectons 84according to the number of the reinforcement member for drainingaccélération. Connectors 84 are connected to the bottom of reinforcement member for draining accélération. The weight matériels can be variedaccording to a shape of the guide casing. Protrusions 86 of FIG. 5A are.intended to drop a reinforcement member without occurrence of twist, whichare coupled to a guide groove at the inside of the guide casing (not shown). FIG. 6 is a perspective view showing a dropping device of areinforcement member for draining accélération according to one embodimentof the présent invention. A dropping unit includes a casing 87, at the topand bottom of which piercing holes 88 and 89 are respectively formed, andalso forms a gâte 90 capable of opening and shutting for putting in and outreinforcement members. To one end of reinforcement member 82 afastening member 91 is coupled. Fastening member 91 which is disposed atthe outer of the top piercing hole 88 of casing 87, is designed _to hâve apredetermined size not to allow it to pass through piercing holes, and to 10 010524 form thc drain by filling with sand after fixing the upper end of thereinforcement member to an inlet for sand. Since fastening member 91 isfor combining the ends of reinforcement member 82, the member 91 doesnot dépend on any spécifie shapes as well as format as shown in the 5 drawing. The other end of reinforcement member 82 is connected to weightmaterial 92 as shown in FIG. 5, so that reinforcement member 82 can beswiftly dropping into the inside of a casing for drain formation through thelower piercing hole 89 without any separate device. FIG. 7 is a perspective view of a guide casing according to one 10 embodiment of the présent invention.
The casing of the présent invention is driven by a predetermined depth into a soft ground and comprises a first member 95 having a polygonalbody. The casing includes also a second member 96, which is connected tothe bottom of pack P, for guiding swiftly pack P into the inside of first 15 member 95. Second member 96 has the same angle as first member 95.Accordingly, when second member 96 is dropped into the inside of firstmember 95, the twist and distortion of pack P is prevented. FIG. 8 is a plan view of the guide casing according to anotherembodiment of the présent invention. As shown in FIG. 8, guide casing 100 20 in this embodiment is integrated with at least one or more reinforcementmembers 101. The reinforcement member 101 is for bending a paper drainboard 102 and guiding it into the inside of casing 100 or preventing thebending of a casing. It is more préférable that paper drain board 102 ismade of easily bendable materials at the portions which are -shown as 25 dotted lines. As described above, since paper drain board 102 is bent and o m 2 a 11 installée! by reinforcement member 101, a wider drain board can be drivenwith a smaller cross-sectional area than in the linearly installed case.Accordingly, a draining effect is largely enhanced and the ground movementis reduced when driven. FïGs. 9A through 9D are plan views of guide casings according todifferent embodiments of the présent invention. As shown in FIGs. 9Athrough 9D, guide casings 110 in these embodiments hâve at least one outerprotrusion 111, respectively. Such protrusions 111 are to prevent bending ofguide casings .1.10 when guide casings 110 are buried underground, 10 respectively. In particular, FIG. 9A is a plan view of guide casings 110consisted of a H-type steel. Here, an intermediate member of H-type Steelplay s a part of a reinforcement member 101. FIG. 10 is a plan view of the pack guide casings in which a pluralityof the pack guide casings are simultaneously buried underground. As can 15 be seen from the drawing, a plurality of the pack guide casings 160 aremutually connected by first connectors 161. Thus, bending of the casing canbe prevented when a plurality of the guide casings are simultaneouslydriven underground, The dotted lines in the drawing represent secondconnectors 162 for effectively preventing the bending of the casing. 20 FIG. 11 is a conceptual view for explaining a drain arranging method according to the présent invention. As shown in the drawing, the drainingmethod according to the présent invention has professes of maintaining avirtua] line which connects a center point of each drain in four rectangulardrains adjacent to each other to form a square, and of arranging a 25 longitudinal axis of each drain perpendicular to the longitudinal axis of an 010524 12 adjacent drain at the center. Thus, an effective draining radius is balancedand a ground sink is also expedited since a draining interval is compact. FIG. 12A is a front view of a driving apparatus according to theprésent invention, and FIG. 12B is a cross-sectional view taken along a 5 direction of I-I of FIG. 12A. As shown in the drawings, the drivingapparatus comprises a guide bar 170, which is vertically installed and towhich a driving member 172 is combined.
At the lower end of driving member 172 a driving block 173 isinstalled, to which an approximately rectangular shape of a holding plate 174 10 is fixed. To holding plate 174 a plurality of guide casings 175A-175D arefixed, which are connected each other with a reinforcement connection plate176, to thus prevent distortion of a casing and maintain its vertical State,thereby constructing a drain having the highest depth. On the other hand,a guide 177 is coupled to guide bar 170 and forms a ho!e that allows guide 15 casings and reinforcement connection plate 176 to pass therethrough, andplays a rôle of guiding the direction when guide casings are buriedunderground, Therefore, at the upper end of holding plate 174 according tothe driving apparatus, a device for providing sand or a drain board isoptionally installed according to use purpose. 20 FIG. 12B is a cross-sectional view taken along a direction of I-I ofFIG. 12A. As can be known in the drawing, the driving apparatus of the.présent invention provides such a device which can drive simultaneously aplurality of drains according to the arrangement type of drains shown inFIG. 11. 25 FIG. 13A is a perspective view of a conventional flexible drain. The 010524 13 flexible drain is in a cylindrical shape and the diameter of the cylindricalshape is limited to a the range between 5cm~25cm. The reason why thesize of the diameter is limited in a fact that normal draining is not attainedif the diameter is less than 5cm, and the flexibility of the drain is inadéquateif the diameter is greater than 25cm. FIG. 13B is a perspective view of a drain structure according to theprésent invention. The structure of the présent invention is in arectangular shape, in which the rectangular shape should hâve a lengthbetween 5cm and 25cm i.n both sides. Thus, the draining solves theinadequacy of the flexibility of the drain. Accordingly, when compared withthe conventional apparatus, the présent invention provides effects that offersexcellent draining, forms a drain with flexibility in horizontal and verticaldirections, and increases a draining contact surface area with cûnsumptionof a small quantity of sand. That is, under the assumption of the sameheight in view of the size shown in the drawings, the drains of FIGs. 13Aand 13B hâve nearly the same volume, but the FIG. 1.3B drain bas muchlarger surface area in view of the circumferential length.
