Description

  The present invention provides a fixing member for fixing a connecting structure formed by connecting a pair of tubular members by a connecting tool to a predetermined surface and a connecting structure formed by connecting a pair of tubular members by a connecting tool, Regarding a plurality of fixing members fixed to each other, in particular, a fixing member suitable for fixing a gas vent pipe provided on a slope of a waste treatment plant, and a plurality of gas vent tubes standing on a bottom surface of the waste treatment plant The present invention relates to a fixing member suitable for fixing.

  Tubular members with passages for fluids (including gases) are used in a wide variety of fields. The tubular member is used as a drain pipe and a gas vent pipe, for example, in a waste disposal site. Here, the “gas vent pipe” is a tubular member provided for releasing the gas generated from the buried waste into the atmosphere. A structure suitable for a gas vent pipe is, for example, a tubular member in which a flow path connecting an outer peripheral surface and an inner peripheral surface is formed on the entire wall in addition to a hollow portion (that is, a conduit) through which a fluid passes. More specifically, it is a network in which continuous filaments made of a thermoplastic resin are irregularly meandered and accumulated, and a flow path is formed by gaps between the filaments.

Providing a gas vent pipe in a waste disposal site is described in Patent Document 1, for example. In Patent Document 1, the vented perforated pipes are arranged in multiple stages on the laying surface of the water shielding sheet in the slope portion of the waste disposal site, extending in a direction intersecting the slope direction of the slope portion, There is disclosed a cover soil structure on the surface of a water shield sheet in which a water shield sheet is laid on the laying surface on which the perforated pipe is disposed, and the cover soil is deposited and held on the surface of the water shield sheet.

  When the tubular member has a circular cross section, it is slippery and difficult to attach to a predetermined surface. In particular, since the slope of the waste disposal site is covered with a plastic water shielding sheet having a smooth surface, it is very difficult to attach a tubular member such as a gas vent pipe on the slope. In particular, in a waste disposal site, it is not permitted to use metal members (eg, iron nails) and to make holes in the water shielding sheet. It is extremely difficult to fix. When the tubular mesh is used as a degassing pipe, the tubular mesh is bulky and has a relatively large outer diameter, and the outer surface thereof is not a continuous surface. The work of fixing to the slope of the field is very complicated.

  A plurality of the above-mentioned tubular nets can be bundled and erected near the center of the bottom surface of the waste disposal site to be used as a degassing structure. This degassing structure is an alternative to the degassing structure conventionally configured by stacking stones, and has the advantage that it can be easily constructed compared to the conventional structure. However, this degassing structure needs to be configured by bundling a plurality of tubular nets (that is, in a bundle) in order to discharge a relatively large amount of gas. This bundle operation is also complicated because it does not give a continuous surface.

  The present invention has been made in view of such circumstances, and a fixing member that makes it possible to attach a tubular member that is difficult to fix to a surface to a desired surface, particularly a waste disposal site. A fixing member that makes it possible to stably fix a tubular member on a water-impervious sheet laid on the surface, and a fixing member that is suitable for fixing a plurality of tubular members that are difficult to bundle themselves It is an issue to provide.

  In order to solve the above-mentioned problems, the present invention is a fixing member for fixing a connection structure formed by connecting a pair of tubular members to each other as a first fixing member, and inserting the connection tool. A fixing member is provided having a first portion having an opening and a second portion attached to the surface and being foldable between the first portion and the second portion. The fixing member inserts a connector into the opening formed in the first part, connects the tubular member to both ends of the fixed connector, and fixes the second part to the surface to which the tubular member is to be attached. Depending on the inclination of the mounting surface, it is used by being bent so that a desired angle, preferably a right angle, is formed between the first part and the second part. Specifically, the connection of the tubular member to the connector is performed by inserting the connector into the open end of the tubular member. This fixing member makes it possible to fix the tubular member connected by the connector to the desired surface by fixing the connector to the desired surface.

  The connecting structure fixed by the fixing member has a configuration in which the connecting tool is inserted into the opening of the fixing member, and the connecting tool is inserted into the opening end of the pair of opposing tubular members. When three or more tubular members are connected, a connecting tool is inserted into both open ends of each tubular member excluding the tubular members located at both ends, and depending on the length and mass of the tubular member, 1 Alternatively, a configuration is adopted in which a plurality or all of the couplers are inserted into the opening of the fixing member. Moreover, this connection structure will have the structure by which the 2nd part of the fixing member was bent in the state fixed to the predetermined surface.

  Here, “fixing the tubular member to the surface” means that the position of the tubular member relative to the surface is not changed. The “tubular member” is a generic term for members having a passage penetrating substantially in the center, and the outer peripheral cross-sectional shape and the cross-sectional shape of the passage may be any shape such as a circle, a rectangle, or a triangle. A “connector” is a member that connects a pair of tubular members by inserting both ends or both halves thereof into the open ends of the pair of tubular members. The connector itself may be a tubular member, or may have a structure in which a groove is provided on the outer peripheral surface so as to form a passage with the inner wall of the tubular member when inserted into the tubular member. It's okay. The “surface” refers to a surface on which the fixing member is to be fixed, and refers to, for example, a wall surface of a building and a slope of a waste disposal site. The boundary between the first part and the second part does not necessarily have to be clearly defined before using the fixing member, and may be determined for the first time when bending is performed. Further, “bendable” means that an angle is formed between the first portion and the second portion in the final use form, and before using the fixing member, It means that it is not always required to be already bent.

  Although this fixing member has a very simple configuration, it is used to fix various tubular members to an arbitrary mounting surface by appropriately selecting the dimensions of the first and second portions and the opening. It has the feature that it can be.

  The tubular member connected by the connector is preferably a flow pipe in which a channel connecting the outer peripheral surface and the inner peripheral surface is formed on the entire wall. Such a distribution pipe is, for example, a tubular net-like body in which continuous filaments made of a thermoplastic resin described in the background art section are irregularly meandered and accumulated, and a flow path is formed by a gap between the filaments. . This tubular net is bulky and it is complicated or difficult to fix itself. However, if the fixing member of the present invention is used, the connector is fixed to a predetermined surface using the fixing member of the present invention. And it becomes possible to attach such a tubular mesh body to a desired surface by the comparatively simple operation | work of connecting a tubular member to the both ends of the fixed coupling tool.

  The present invention is a fixing member for fixing a plurality of connecting structures each having a pair of tubular members connected by a connecting tool as a second fixing member, and having an opening for inserting the connecting tool. A plurality of fixing members are provided. In other words, the second fixing member can give a structure in which a plurality of connection structures, which are elongated by connecting tubular members with a connector, are bundled. According to this fixing member, the coupling tool is inserted into each of the plurality of openings, and both ends or both halves of each coupling tool are inserted into the opening end of the tubular member. A configuration with a fixed fixed position is obtained. That is, when this fixing member is used, for example, a tubular member having a large diameter or a tubular member whose tube wall is a net-like member is bundled with each other, and a work of tying with a rope or the like is not necessary, and a tubular member having an arbitrary configuration can be obtained. It is possible to easily obtain a configuration that is bundled by the number of.

The present invention is also a method for fixing to a surface a connection structure formed by connecting a pair of tubular members by a connector.
(A) attaching the second portion of the first fixing member of the present invention to a surface;
(B) bending between the first part and the second part;
A method is provided that includes (c) inserting a connector into the opening of the securing member, and (d) inserting the connector into the opposed open ends of the pair of tubular members. As described above, this method is preferably implemented as a method for efficiently connecting and fixing large-diameter tubular members. The operations (a) to (d) do not need to be performed in this order. For example, after performing (c) first, after performing (d) to obtain a connection structure, the fixing member is moved. You may attach | subject to operation of (a) and (b). Further, by repeating the operations (a) to (d) twice or more, three or more tubular members can be connected and attached to a predetermined surface. In the method of the present invention, the tubular member connected by the connector is preferably a flow pipe in which a channel connecting the outer peripheral surface and the inner peripheral surface is formed on the entire wall.

  The above-described method of the present invention is particularly preferably performed when a tubular member is attached to the surface of a water shielding sheet laid on the slope of a waste disposal site. In that case, it is preferable that at least one of the materials constituting the fixing member and at least one of the materials constituting the water-impervious sheet be a similar resin, and more preferably a similar thermoplastic resin. The “same resin” refers to a resin included in a group called olefin, ester, amide, vinyl chloride, acrylic, and urethane. The similar resins can be bonded satisfactorily in both cases where the resin itself is softened or melted and bonded using an appropriate adhesive. In particular, since the thermoplastic resin melts or softens by heating and exhibits adhesiveness, if the fixing member and the water shielding sheet are composed of the same type of thermoplastic resin, the fixing member can be easily and satisfactorily formed into the water shielding sheet by the thermal bonding treatment. Can be attached to. Therefore, the method of the present invention is suitably implemented in a waste disposal site where the use of metal members is prohibited by appropriately selecting materials for the fixing member and the water shielding sheet.

  The first fixing member of the present invention has a shape configuration including a first part having an opening for inserting a connector and a second part that can be bent from the first part and attached to a predetermined surface, By inserting the tool into the opening and fixing the tool to a predetermined surface, the pair of tubular members connected by the connector are fixed to the surface. Accordingly, by appropriately selecting the dimensions of the coupling tool according to the tubular member, and the first and second portions of the first fixing member and the opening, etc., a variety of tubular members are supported on the fixing member, The fixing member can be attached to the desired surface, thereby fixing the tubular member. Further, the fixing member is made of a material containing at least one thermoplastic resin as a constituent material, so that a desired surface, in particular, a surface made of a material containing a resin similar to the thermoplastic resin included in the fixing member can be heated. It can be attached by bonding. Therefore, if the first fixing member of the present invention is used, a hole is made in the water shielding sheet without using a metal member on the surface of the water shielding sheet laid on the slope of the waste disposal site. Instead, the fixing member can be attached using the thermal adhesiveness of the fixing member.

  The second fixing member of the present invention has a shape configuration having a plurality of openings into which the couplers are inserted, and a plurality of couplers are inserted into the openings to fix the positions of the pair, thereby forming a pair of tubular members. A plurality of connection structures (that is, a plurality of pairs of tubular members) formed by connecting members with a connector are fixed to each other. Therefore, according to this fixing member, it is possible to easily obtain a structure in which a plurality of various tubular members are bundled by appropriately selecting the size and the number of the connector and the opening according to the tubular member. it can.

Hereinafter, embodiments of the present invention will be described with reference to the drawings as necessary.
First, a first fixing member of the present invention, that is, a fixing member for fixing a tubular member connected by a connector to a predetermined surface, and a method for fixing the tubular member to a predetermined surface using the same will be described. . The 1st fixing member of this invention has the 1st part which has an opening part which inserts a coupling tool, and the 2nd part attached to a surface. The first portion and the second portion can be bent, and the boundary between the two portions is determined by the bending.

  The fixing member of the present invention is preferably a sheet-like material. The sheet-like material is thin and easy to handle, and is easy to bend. The sheet-like material may be, for example, a laminated sheet composed of a thermoplastic resin sheet, a nonwoven fabric sheet, a metal sheet, and two or more sheets selected from these sheets.

  Preferably, the fixing member of the present invention is a sheet-like material made of a thermoplastic resin. The thermoplastic resin is melted or softened by applying heat and pressure as necessary, and exhibits thermal adhesiveness. Therefore, the fixing member made of the thermoplastic resin is a predetermined operation by a simple operation using a hot air welder or the like. Can be attached to a surface. In particular, since the water shielding sheet of the waste disposal site is generally made of a thermoplastic resin, the fixing member made of the thermoplastic resin is suitable for fixing to the surface of the water shielding sheet by thermal bonding.

  Examples of the thermoplastic resin constituting the fixing member include homopolymers and copolymers of olefin monomers such as ethylene and propylene, and copolymers of olefins such as ethylene and propylene and monomers copolymerizable therewith. And olefin resins such as polyethylene terephthalate and polybutylene terephthalate, and amide resins such as nylon-6. These resins may be used alone or in combination of two or more. More specifically, the thermoplastic resin constituting the fixing member is selected from high density polyethylene, polyethylene polymerized by a metallocene catalyst (low density polyethylene), ethylene propylene diene rubber (EPDM), polypropylene and vinyl chloride 1 Or it is preferable that it is resin which has several resin as a main component. For example, when a fixing member is attached to the slope of a waste disposal site, it is preferable to use a polyethylene resin polymerized with a metallocene catalyst having a high tensile strength and a high thermal bonding strength.

  When the fixing member is attached to the water shielding sheet of the waste disposal site, it is preferable that at least one of the thermoplastic resins constituting the fixing member is the same as at least one of the thermoplastic resins constituting the water shielding sheet. . By using the same material for the surface to which the fixing member and the fixing member are attached, the thermal bonding strength can be further improved. Resin types are olefin type (polypropylene, polyethylene, ethylene propylene diene rubber, etc.), ester type (polyethylene terephthalate, polybutylene terephthalate), amide type (nylon 6, nylon 66), vinyl chloride type (polyvinyl chloride), urethane type (Polyurethane). For example, when the material constituting the water shielding sheet includes polypropylene which is an olefin resin, the fixing member is a material including polyethylene, polypropylene, or ethylene-propylene diene rubber polymerized by a metallocene catalyst which is an olefin resin. Are preferably formed. More preferably, the fixing member is made of the same material as that of the water-impervious sheet. Specifically, the fixing member is manufactured by appropriately processing a sheet-like material (that is, the original sheet of the water-impervious sheet) to be the water-impervious sheet It is preferable to do.

  The thickness of the sheet-like fixing member is not particularly limited, and is preferably 0.5 to 3 mm, for example. If the thickness of the fixing member is too small, the mechanical strength may be reduced and may be damaged during the operation of fixing the tubular member. If the thickness is too large, it may be difficult to bend. .

  The dimension of the fixing member is sufficiently large so that an opening having a desired dimension is formed according to the outer diameter of the coupling tool to be inserted, and the tubular member coupled by the coupling tool is arranged on a predetermined surface. It is determined in consideration of the dimensions and mass of the connecting member and the tubular member so that the fixing member includes a first portion having a thickness and a second portion having a size sufficient to be attached to a predetermined surface. . The diameter of the opening formed in the first part is the same as or slightly smaller than the outer diameter of the connector so that the connector is less slippery after the connector is inserted into the opening. It's okay. The first part has a distance between the boundary between the first part and the second part (i.e., the folding line) and the lower end of the opening (i.e., the position closest to the boundary in the outline of the opening), The dimension needs to be larger than the wall thickness of the tubular member connected by the connector. The first portion is also a portion corresponding to the distance when the tubular member connected by the connector should be located at a desired distance from the bent portion when the second portion is folded from the first portion. It is necessary to make the dimensions including. Moreover, when fixing a some tubular member (namely, several connection tool) at once, let the 1st part be a shape and a dimension that a some opening part is formed.

  A 2nd part is a part used for attachment, The dimension is suitably selected according to the attachment method, the dimension, mass, etc. of a connector and a tubular member. When the second portion is small, it is difficult to stably attach the fixing member to a predetermined surface, and the fixing member may come off or be damaged after being attached.

  As described above, the boundary between the first part and the second part may not be clearly defined before use, in which case the fold line formed in use is the boundary between the parts. Become. When the bent portion of the fixing member is curved and a clear bend line is not formed, the portion in contact with the mounting surface is defined as the second portion.

  FIG. 1 schematically shows one form of a fixing member of the present invention in a plan view, and FIG. 2 shows a fixing member shown in FIG. 1 attached to a predetermined surface, and a pair of tubular members are connected by a connector. A state in which the connecting structure is fixed is schematically shown in a side view of the vicinity of the connecting portion in a sectional view. A fixing member 10 shown in FIG. 1 is a rectangular sheet-like material having a first portion 2 and a second portion 4, and an opening 6 is provided in the first portion 2. The opening 6 is separated from the folding line f formed between the first part and the second part by a distance h. The fold line f is virtual in FIG. If necessary, the folding line may be displayed in advance, and in this case, the folding operation can be easily performed. As shown in FIG. 2, the fixing of the tubular member 28 by the fixing member 10 is performed by bending the fixing member 10 so as to form a bending line f, attaching the second portion 4 to a predetermined surface 22, and connecting the opening 6 to the connector. 20 is inserted, and the connector 20 is inserted into the open ends of the two tubular members 28. In FIG. 1, the distance indicated by the symbol h corresponds to the distance between the fixed surface 22 and the opening 6 in FIG. 2, and this distance h is the thickness of the wall of the tubular member 28 (more precisely, It is necessary to be larger than the combined length of the tubular member and the fixing member. If h is smaller than the wall thickness of the tubular member 28, the connector cannot be inserted into the tubular member.

  The fixing member 10 shown in FIG. 1 has a configuration in which both the first portion 2 and the second portion 4 have the same width when the direction parallel to the folding line f is the width direction. The first part and the second part do not necessarily have the same width, and as long as an opening is formed in the first part, the width of the first part may be smaller than the width of the second part, Or you may enlarge. FIG. 3 shows the fixing member 30 in which the width of the first portion 32 is narrower than the width of the second portion 34.

  Further, the first part and the second part may have a shape other than a rectangle, for example, one or both may be a triangle or a polygon. However, when the fixing member has a rectangular shape as shown in FIG. 1 as a whole, the fixing member can be manufactured at a lower cost and more efficiently.

  In FIG. 2, the tubular member 28 is shown as a general cylindrical tubular member with a generally circular passage therethrough. The pair of tubular members 28 are connected to each other by inserting a half of the tubular connector 20 into one open end. Or you may use a connection tool in the form that only the both ends are inserted in a tubular member, and a part is exposed. The connector 20 can be of any form depending on the type and size of the tubular member 28, and is not limited to the shape shown in the figure. In the illustrated form, the connector 20 has a flange 20a as an overhanging portion. The connector 20 having the flange 20a is preferably used because it can be easily positioned by the method in which the opening 6 is inserted until the flange contacts the fixing member 10 and is not easily displaced from the fixing member. It is preferable that the flange 20a has an annular shape or a polygonal shape such as a quadrangular outer peripheral shape. Alternatively, the flange 20a may be formed intermittently in the circumferential direction of the connector 20 by cutting a part of the annular shape in the radial direction. Alternatively, the protruding portion of the connector may not be a flange, but may be one or a plurality of protrusions, and the protrusion may be brought into contact with the periphery of the opening to perform positioning of the connector. The protruding portion of the connector may have any shape as long as it protrudes or expands from the outer periphery of the connector so as to contact the periphery of the opening of the fixing member.

  The tubular member fixed by the connector is preferably a flow pipe in which a channel connecting the outer peripheral surface and the inner peripheral surface is formed on the entire wall. Such a flow pipe is a tubular member whose pipe wall is made of a porous material having a high porosity. The flow pipe is preferably a tubular network in which continuous filaments made of a thermoplastic resin are irregularly meandered and accumulated, and the flow path is formed on the entire wall by gaps between the filaments. A perspective view of such a tubular mesh is schematically shown in FIG. 5, and an apparatus for manufacturing the same is schematically shown in FIG.

  As shown in FIG. 4, the tubular net-like body is disposed in an outer restricting tool 302 having a cylindrical through hole 306 penetrating in the vertical direction, and an upper end opening of the through hole 306 of the outer restricting tool 302. Manufactured using a restricting tool 300 including a cylindrical inner restricting tool 304. Specifically, the melted thermoplastic resin filament melted and kneaded by an extruder is irregularly meandered in the space formed between the opposed inner surfaces of the inner and outer restricting devices 300 and 304. While supplying and accumulating. Next, the assembly is sent downward from the outer restricting tool 302 through the lower opening, cooled in the cooling water tank, continuously taken out by the take-up machine, and taken out from the cooling water tank. As a result, a tubular (cylindrical) flow pipe 200 having a constant wall thickness is manufactured. As shown in FIG. 5, the circulation pipe 200 provides a large number of flow paths 202 in which gaps formed between filaments connect the outer peripheral surface and the inner peripheral surface. Therefore, the flow pipe 200 can flow a fluid such as a liquid or a gas from the inner side to the outer side of the flow pipe 200 or from the outer side to the inner side of the flow pipe 200 through the flow path 202.

  An example of a connection tool particularly suitable for connecting the tubular mesh is shown in FIG. The connector 100 is formed in a cylindrical shape having an outer diameter substantially matching the inner diameter of the flow pipe 200 and having a flow hole 110 penetrating in the length direction, and both end portions 110 in the length direction are slightly reduced in diameter. It is in a state.

  An annular partition 104 having a constant width and a constant thickness in contact with the opening end surface of the flow pipe 200 is located at the center in the length direction of the connector main body 102 with respect to the outer peripheral surface of the connector main body 102. The connector main body 102 is formed in a direction orthogonal to each other, and the appearance of the connector main body 102 is half of the partition 104 (in FIG. 6A, the lower portion of the partition 104 in the connector main body 102). , And the other half (in FIG. 6A, the upper part of the partition 104 in the connector main body 102). In addition, it is preferable that the partition part 104 is an annular | circular shape or polygonal shape, such as a square in outer periphery shape. Alternatively, the partition 104 may be formed intermittently in the circumferential direction of the connector main body 102 by cutting a part of the annular shape in the radial direction. The partition portion 104 can function as the above-described protruding portion when the connector 100 is fixed by a fixing member.

  Further, on the outer peripheral surface of the connector main body 102, a number of locking projections 120, 120 ',... For locking in the flow path 202 provided on the wall of the flow pipe 200 are formed. Specifically, all the locking projections 120 and 120 ′ are formed in a truncated quadrangular pyramid shape, and the insertion-side end surface 121 of the locking projection 120 into the opening end portion 204 of the flow pipe 200 of the connector main body 102. The peripheral end surfaces 122 and 122 of the connector main body 102 are formed as inclined guide surfaces having an obtuse angle with respect to the outer peripheral surface of the connector main body 1, while the central end surface 123 of the locking projection 120 is connected. The angle formed with respect to the outer peripheral surface of the tool main body 1 is formed on a locking surface having an acute angle (see FIGS. 6B and 6C). These locking projections 120, 120 ′,... Are formed by obliquely cutting the connector body 102 at an angle a with respect to the axis X of the connector body 102, as shown in FIG. Three or more (six in FIG. 7) are provided on the four elliptical virtual lines 130 that are parallel to each other with a predetermined interval. In the illustrated coupling tool, a locking projection 120 ′ is further provided at a portion other than the imaginary line 130, but the locking projection 120 ′ may not be provided. As described above, since the locking projections 120 and 120 ′ are formed in a state of being dispersed on the outer peripheral surface of the connector main body 102, the locking protrusion 120 of the connecting device 100 of the flow pipe is set to the length of the connector main body 102. Can be locked to the flow path 202 of the flow pipe 200 without deviation in the direction and the circumferential direction, and one half or the other half of the connector 100 of the flow pipe 200 is entirely within the open end 204 of the flow pipe 200. It can be fixed stably.

  FIG. 8 schematically shows a state in which this connecting tool is fixed to a predetermined surface by the fixing member of the present invention, and two tubular nets are connected by the connecting tool. FIG. 8 shows the vicinity of the connecting portion in a sectional view and a side view of other portions. The fixing member 40 shown in FIG. 8 has the same configuration as the connector shown in FIG. The connector 100 passes through the opening 46 provided in the first portion 42, and the partition portion 200 is in contact with the first portion 42 at the opening 46. The second portion 44 is bent and attached to the surface 48. Both halves of the connector 100 are inserted into the tubular mesh 200, and the locking protrusions in the connector are locked into the through holes of the flow tube, so that the flow tubes are connected in series.

  As described above, the distance h between the opening 46 and the surface 48 in the fixing member after being bent needs to be larger than the thickness of the flow pipe 200 that is positioned around the opening h. If h is smaller than the wall thickness of the flow pipe 200, the connector cannot be inserted into the flow pipe.

  As shown in FIG. 11 described later, the outer peripheral shape of the tubular mesh used as the flow pipe 200 is preferably rectangular. The tubular net having a rectangular outer peripheral shape has the advantage that it is difficult to roll during construction and can be stably fixed to the mounting surface because the area of the portion close to the mounting surface is large. Furthermore, the tubular net-like body having a rectangular outer peripheral shape can be stably bundled when two or more bundles are used as will be described later.

  In one preferred embodiment, the fixing member of the present invention may have a plurality of openings in the first portion, and fix the plurality of connectors and the tubular member to a predetermined surface at a time. Examples of such a fixing member are shown in FIGS. 9 (a) and 9 (b). The fixing member 50 shown in FIG. 9A has a first portion 52 provided with three openings 56. The fixing member 50 is also bent at the folding line f, and the second portion 54 is attached to the mounting surface for use. The fixing member 70 shown in FIG. 9B has a first portion 72 provided with two openings 76. The fixing member 70 is also bent at the folding line f and the second portion 74 is attached to the mounting surface for use. The number of openings can be arbitrarily selected according to the number of tubular members to be fixed. Moreover, when using the fixing member which has a some opening part, it is necessary to take sufficient space | interval between opening parts in consideration of the thickness of the tubular member located around a coupling tool. In FIG. 9, the virtual line which divides | segments a 1st part is shown with the broken line, and the dimension which the tubular member connected by a connection pipe can take is represented.

The circulation pipe, particularly when used as a degassing pipe at a waste disposal site, is covered with a biodegradable nonwoven fabric with its outer peripheral surface (that is, the outer surface parallel to the longitudinal direction) covered with a connector. It is preferable to be connected and fixed by the fixing member of the present invention. Immediately after starting the accumulation of waste at the waste disposal site, the waste tends to flow because it contains a lot of liquid such as water, and may block the flow path of the distribution pipe. As a result, it may be difficult to release the gas generated from the waste into the atmosphere. Covering the outer peripheral surface of the flow pipe with a biodegradable nonwoven fabric effectively prevents the waste from flowing into the flow path, although the passage of gas from waste to the flow pipe is somewhat reduced in the initial stage. The This biodegradable nonwoven fabric is biodegraded when the waste water is discharged as the waste deposit progresses, and the waste becomes hard. Is hardly affected. Thus, use of a biodegradable nonwoven fabric makes it possible to more effectively utilize the function of the distribution pipe. Covering the outer peripheral surface of the flow pipe with a biodegradable nonwoven fabric may be carried out by sticking a plurality of non-woven fabrics, or simply wrapping one non-woven fabric around the outer peripheral surface of the flow pipe and Accordingly, a part of the nonwoven fabric may be fixed to the flow pipe. As the biodegradable nonwoven fabric, for example, a hydroentangled nonwoven fabric made of rayon and having a basis weight of about 10 to 100 g / m ² can be used.

Next, a method for fixing the tubular member to a predetermined surface using the fixing member of the present invention will be described. As described above, the fixing method of the present invention includes:
(A) attaching the second part of the first fixing member of the present invention to the surface;
(B) bending between the first part and the second part;
(C) inserting the connector into the opening of the securing member, and (d) inserting the connector into the opposed open ends of the pair of tubular members.

  The second portion of the securing member may be attached to the mounting surface using, for example, an adhesive, a nail, or a screw. When the fixing member is made of a thermoplastic resin and the attachment surface has a property of adhering to the thermoplastic resin, it is preferable to attach the second portion of the fixing member to the attachment surface by thermal bonding. Thermal bonding may be performed, for example, using a hot air welder (eg, a Leister hot air welder). Alternatively, thermal bonding may be performed using an ultrasonic welder or a high frequency welder.

  The step of bending between the first part and the second part is preferably performed at the construction site. Alternatively, the bending step may be performed before the second portion is attached to the predetermined surface (that is, as a preparation step). The bending may be performed, for example, while pressing the second part simultaneously with the attachment of the second part. When the fixing member is thick and difficult to bend, a shallow cut may be made along the folding line of the fixing member to facilitate bending. For example, when the second portion is attached to the slope of the waste disposal site, the second portion may be attached so as to be positioned above the first portion, or may be attached so as to be positioned below.

  Inserting the connector into the opening of the fixing member is performed so that the connector is arranged at a predetermined position. For this purpose, for example, the protruding portion may be provided on the connecting tool, and the connecting tool may be positioned by bringing the protruding portion into contact with the first portion.

  The insertion of the connector into the opening of the fixing member is preferably carried out so that the half of the connector extends equally on both sides of the first part of the fixing member. For this reason, the overhanging portion (corresponding to the partition portion in the coupling device described with reference to FIG. 6A) is provided at a substantially half position of the coupling tool, and the coupling tool is brought into contact with the first portion. Is preferably inserted.

  A pair of (ie, two) tubular members are connected by inserting a connector into each open end to form a single connection structure. For example, the tubular member may be advanced to a position where it contacts the first portion of the fixing member. As described above, the pair of tubular members to be connected is preferably a flow pipe in which a channel connecting the outer peripheral surface and the inner peripheral surface is formed on the entire wall.

  By repeating the operations (a) to (d), it is possible to connect three or more tubular members and extend the tubular members over a long distance. In that case, in the second and subsequent operations, one of the pair of tubular members is already connected to another tubular member with the connecting tool already inserted into one open end (d) above. It is attached to the connecting operation. Thus, for example, to smoothly connect the tubular members A, B, and C, after connecting A and B, the connector is inserted into the open end of B, and then one half of the connector is fixed. It is preferable to insert into the opening of the member (which may already be folded), fix the fixing member to the mounting surface, and then insert the other half of the connector into the tubular member C. Thus, when fixing the tubular member using the connector, the operations (a) to (d) are not necessarily performed in this order. Depending on the mass and length of the tubular member and the state of the attachment surface, it is not always necessary to insert all the coupling tools into the fixing member. In this case, the operation (c) may not be performed.

  In the method including the operations (a) to (d) described above, preferably, a fixing member is attached to the surface of the water shielding sheet laid on the slope of the waste disposal site, and a desired tubular member is fixed to the surface. It is preferable that the method is implemented. In particular, the tubular member connected by the connector is the above-described tubular mesh described with reference to FIGS. 4 and 5, and the connector has the structure described with reference to FIGS. 6 (a) and 7. The connected structure acts as a degassing pipe for releasing the gas generated from the waste into the atmosphere.

  When using a tubular mesh (or other distribution pipe), as described above, the outer peripheral surface of the tubular mesh is biodegraded to prevent clogging at the start of waste accumulation. It is preferable to cover with a conductive nonwoven fabric. The operation of covering the tubular mesh body with the biodegradable nonwoven fabric is performed by a method of attaching a plurality of nonwoven fabrics to the outer peripheral surface of the tubular mesh body, or winding one nonwoven fabric. Whichever method is used, it is preferable from the viewpoint of efficiency that the operation is performed before the coupling tool is inserted into the open end of the tubular mesh. The biodegradable nonwoven fabric is preferably the rayon hydroentangled nonwoven fabric described above.

  FIG. 10 and FIG. 11 schematically show, in a cross-sectional view and a perspective view, a configuration in which a degassing pipe is fixed to a slope of a waste disposal site using a tubular mesh body and a connector. The slope 300 has a structure in which, for example, two inclined faces 300a having a slope of 1: 2 and a height of 5 m are connected by a small step 300b having a width of about 2 m. On the slope 300 and the bottom surface 302, a lower protective mat 60, a lower water shielding sheet 62, an intermediate protective mat 64, and a surface side water shielding sheet 66 are laid in this order. The connector 100 is fixed by the fixing member 70, and both halves of the connector 100 are inserted into the tubular mesh 200, whereby the tubular mesh 200 is connected to form a long gas vent tube. . In the form shown in the figure, the connected nets are composed of two types, a straight net 200a and a bent net 200b corresponding to the bent part of the small step 300b. A light shielding protective mat 68 is laid on the surface of the gas vent pipe.

  As schematically shown in FIG. 11, the tubular network 200 has, for example, a square outer shape of 100 mm × 100 mm, a flow path having a diameter of 50 mm in the center, and the length per one is, for example, 4m or 2m. For example, two tubular nets are arranged and fixed at intervals of about 10 m using a fixing member having two openings.

  The connector 100 has, for example, the shape shown in FIGS. 6A and 7, and has a width at the center of a cylindrical connector body 102 having an inner diameter of 40 mm, an outer diameter of 50 mm, and a length of 250 mm. Has a configuration in which an annular partition 104 having a thickness of 10 mm and a thickness of 2 mm is formed in a direction orthogonal to the outer peripheral surface of the connector main body 102. The locking projection 120 is formed by, for example, two elliptical virtual lines parallel to each other formed by obliquely cutting the connector body 102 at an angle of 25 ° with respect to the axis X of the connector body 102. Six pieces are formed on each of 130. Further, the distal end portion and the base end portion (side closer to the partition portion) of the outer peripheral surface of each half portion of the connector main body 101 are positioned 180 ° in the circumferential direction of the connector main body 102 in a state of being detached from the virtual line 130. Two locking protrusions 120 ′ may be provided with a phase difference.

  For example, as shown in FIG. 9B, the fixing member 70 is a square of 20 cm × 20 cm as a whole, and can be bent substantially in half. The first portion 72 and the second portion 74 each have a dimension of 20 cm × 10 cm. In the first portion 72, an opening 76 having a diameter substantially the same as the outer diameter of the connector main body is provided at the center of each region obtained by dividing the first portion 72 so as to correspond to the cross sections of the two tubular nets. Provided.

  The fixing member 70 is preferably attached to the surface-side water-impervious sheet 66 by a method in which the second portion of the fixing member is melted or softened with hot air and is thermally bonded or thermocompression bonded. In order to strengthen such thermal bonding or thermocompression bonding, at least one of the materials constituting the fixing member 70 is a thermoplastic resin, and is similar to at least one of the thermoplastic resins constituting the surface-side water-impervious sheet 66. It is preferable.

  The lower protective mat 60, the lower water-impervious sheet 62, the intermediate protective mat 64, and the front-side water-impervious sheet 66 are arbitrarily selected from non-woven fabrics or sheets that are normally used when constructing a waste disposal site.

  In the above, the method of using the fixing member of the present invention for fixing the degassing pipe of the waste disposal site has been described. The use of the fixing member of the present invention is not limited thereto, and in general civil engineering work, a desired tubular member (for example, an exhaust pipe, a drain pipe, an air supply pipe, a water supply pipe) is installed on a desired surface. Can be used.

  Next, a second fixing member according to the present invention, that is, a fixing member in which a plurality of connecting structures formed by connecting a pair of tubular members with a connecting tool are bundled will be described. The second fixing member needs to have a plurality of openings for inserting the communication tool. In the second fixing member, the interval between the openings will be described with reference to FIG. As described above, it is necessary to make the tubular member sufficiently wide in consideration of the thickness of the tubular member.

  The second fixing member is the same as the first fixing member except that a plurality of openings are required and the second portion is not necessarily required. Therefore, the second fixing member is also preferably formed as a sheet using the materials mentioned in relation to the first fixing member. Unlike the first fixing member, since the second fixing member is not attached to the surface, it is not necessary to select the material of the second fixing member in consideration of the material (for example, resin) constituting the surface. However, when a plurality of tubular members are bundled with the second fixing member to constitute a degassing structure of the waste disposal site, the second fixing member is preferably made of a material other than metal, It is preferable to use the resin exemplified above. Moreover, also when using this fixing member, it is preferable to provide an overhang | projection part in a connection tool.

  The second fixing member as a bundle member for bundling a plurality of connection structures is, for example, a gas vent formed by bundling a plurality of (for example, four) connection structures of the above-described connector and a tubular mesh-like body connected thereto It is preferably used when the structure is installed at the center of the bottom surface of the waste. FIG. 12 schematically shows a gas vent structure formed by bundling four connecting structures using the fixing member of the present invention. In the illustrated gas vent structure 400, the connecting tool 100 is inserted into the opening 82 of the fixing member 80, and both ends of the inserted connecting tool 100 are inserted into the opening end of the tubular mesh 200 to connect the connecting structure. 800 is formed. In the illustrated form, each connection structure 800 is configured by sequentially connecting short (for example, about 1 to 2 meters) tubular members with a connector. Moreover, in each connection structure, the connection tool is being fixed with respect to the connection tool of another connection structure by the fixing member of this invention. Therefore, the amount of deflection generated in each connection structure is relatively small. On the other hand, when a long tubular member (that is, a continuous tubular member without using a connector) is bundled at a time, the tubular member may be greatly bent, and the bundling operation may be difficult. Therefore, the second fixing member of the present invention is also useful in that it is possible to obtain a structure in which a plurality of tubular members are bundled in a stable form with good workability.

  The first fixing member of the present invention makes it possible to easily fix tubular members that are difficult to fix to a slope or a vertical surface to those surfaces, and is laid on a slope, particularly in a waste disposal site. It is useful as a member for fixing the gas vent pipe to the surface of the water-impervious sheet. In addition, the second fixing member of the present invention makes it possible to stably construct a structure in which long tubular members are bundled, and is formed at the center of the bottom surface particularly in a waste disposal site. This is useful as a member for fixing a plurality of gas vent pipes constituting the gas vent structure to be fixed together.
