Description

Geogrid bag with joint part and connection method thereof

The invention relates to a geotechnical sand sausage bag, in particular to a geotechnical sand bag with a joint portion and a connecting method thereof.

Geotechnical sand bags are usually used in river and sea engineering or environmental engineering, and can be used to construct marine structures such as breakwaters, jetties, dikes, etc., or to prevent sandstone from being washed away by river water or waves.

The geotechnical sand intestine bag is generally composed of geotextile weaving cloth, filled with sand stone, soil or other filling materials, and forms a flexible water-permeable structure after the filling is completed, which has the function of dissipating the impact force of the water flow.

Referring to Figures 1 and 2, the conventional geotechnical sand bag is processed by first forming a tubular bag body 91 by ground weaving, and then sewing the two ends of the bag body 91 with two sealing stitches 92 to close the mouth. closure.

Since the stitching manner causes the height of the bag body 91 adjacent to the sealing seam 92 to begin to decrease, if the two geotextile bags are to be joined, the ends of the two are overlapped ( See Figure 3), however, this approach will result in a gap and a height drop at the overlap, making it easier for the water flow to pass therethrough, thereby reducing the erosion control effect of the overall structure. And when the sand bags are stacked, the elevation difference at the end of the lower sand bag will cause the upper sand bag to collapse or protrude, which may result in discontinuous gaps, which is unfavorable. The stability of the overall structure.

In addition, since the left and right adjacent sand intestine bags cannot be closely connected and fixed, there may be misalignment between the front and the rear, which also makes the water flow easy to pass, which affects the erosion control effect of the overall structure.

In order to solve the problem of the connection of the sand bag in this place, the patent number US8777523 discloses a geotechnical sand bag, which comprises a tubular bag body, two in accordance with the tubular section of the bag body and respectively coupled to the bag body. The flat plates at both ends and the plurality of straps are connected to each other so that the flat plates of the two geotechnical sand sausage bags are butted together, and the sandbags are connected by the straps.

However, since the flat plates, the bag bodies and the straps of the single sand bag are separate elements, the joints are likely to form a weakness of the overall structure, taking the most commonly used stitching method as an example. During the suturing process of the flat plate and the bag body, the puncture of the needle needle inevitably causes damage to the fabric, so that the tensile strength of the stitching portion is lowered. Therefore, during the filling process, the stitching portion of the fabric will be pulled by the suture, and the force is relatively non-stitched. It is more concentrated, so it is easier to break down there. Therefore, in the patent, the flat plate and the bag body are respectively closed by the closed seam of the bag, and the stitching area is increased compared with the straight sealing method of FIGS. 1 and 2, so the probability of the damage of the ground sand bag is also Increase.

In addition, during the filling process, the bottom position of the flat sanding bag and the bag body is not only subjected to the filling pressure, but also needs to bear the gravity of the filling material, so there is a structural weakness at the place. At this time, the probability of destruction will increase greatly, so this method solves the aforementioned problem of discontinuous gap, but reduces the overall structural strength.

In addition, during the filling process, the ground sand intestine bag is often broken due to excessive filling pressure, and the sand bag is broken during filling, and the sand bag of the ground is broken when it is filled, except Leading to the failure of the whole item, and because the bag inside the sand bag is a high-pressure environment before the rupture, and the size of the bag is usually very large, the large amount of filling material that rushes after the rupture has a strong impact and will be around The safety of construction personnel and machinery poses a major threat.

Accordingly, it is an object of the present invention to provide a method for joining a sand bag with a joint portion and a method of joining the same.

Therefore, the present invention has a joint portion of a sand bag, comprising a bag unit, an auxiliary unit, an oral suture, and two auxiliary sutures.

The bag unit includes a surrounding portion around an axis, a substantially planar end disposed at one end of the surrounding portion along the axis, and a receiving space defined by the surrounding portion and the end portion The auxiliary unit is integrally connected to the end portion, and includes two connecting portions respectively connected to opposite sides of the end portion, and two buffer spaces respectively defined by the connecting portions, and the sealing suture is disposed at the end portion And the connecting portions respectively enclosing the accommodating space and the buffer spaces, wherein the auxiliary sutures are respectively disposed between the connecting portions and the end portions and intersecting the sealing sutures to isolate the buffer spaces and the Accommodate space.

The utility model has the advantages that: the sealing suture, the auxiliary sutures and the connecting portions integrally connected with the bag body unit are arranged, the end portion is presented after the filling of the sand bag in the ground Plane, to improve the tightness and bonding strength of the end of the sandbags of two adjacent places, and when the filling pressure is too large, the auxiliary stitches can be broken first to make the corresponding joints bulge, let Therefore, the user can obtain early warning after the warning, so as to avoid damage to the sand bag.

Therefore, the method for joining the sandbags of the present invention is applied to join two ground sand sausage bags having the joints as described above, and the method firstly connects the joints of one of the sandbags to the other The connecting portions of the sandbags of one place are connected to each other, and finally a filler is filled in the sand bags of the respective sands.

The effect of the invention is that since the two adjacent sand bags can be joined before filling, the two can form a tight joint after filling.

Therefore, the method for joining the sandbags of the present invention is applied to join two ground sand sausage bags having the joints as described above, and the method first fills one of the sandbags with a filler, and then The connecting portions of the grit bag that have been filled with the filling are respectively connected to the connecting portions of another grit bag that has not been filled with the filling, and finally the filling has not been filled. Another ground sand bag fills the filling.

The effect of the invention is that since the two adjacent sand bags can be connected before the filling is completed, the two can be tightly combined after filling.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

Referring to Figures 4 and 5, a first embodiment of the present invention is a bag body unit 2, an auxiliary unit 3, an oral suture 4, and two auxiliary sutures 5.

The bag unit 2 includes a surrounding portion 21 surrounding an axis L, a substantially planar end 22 disposed at one end of the surrounding portion 21 along the axis L, and a surrounding portion 21 and the end portion 22 collectively around the defined containment space 23.

The auxiliary unit 3 is integrally connected to the end portion 22 and includes two connecting portions 31 respectively connected to opposite sides of the end portion 22, and two buffer spaces 32 respectively defined by the connecting portions 31.

The sealing suture 4 is disposed at the end portion 22 and the connecting portions 31 to respectively close the accommodating space 23 and the buffer spaces 32.

The auxiliary sutures 5 are respectively disposed between the connecting portions 31 and the end portions 22 and intersect the sealing sutures 4 to isolate the buffer spaces 32 and the accommodating spaces 23.

In the embodiment, the bag unit 2 and the auxiliary unit 3 are integrally formed, and the sealing suture 4 and the auxiliary suture 5 are subsequently sewn, and the sealing suture 4 is linear, each An auxiliary suture 5 is linear, the strength of each auxiliary suture 5 is lower than the strength of the sealing suture 4, and each auxiliary suture 5 is perpendicular to the sealing suture 4, and the end portion 22 is Similar to the shape of a rectangle.

When in use, the filling space 23 is filled with a filling (not shown). When the ground sand bag is filled, the end 22 will be filled after the filling of the sand bag. Presenting a plane, and the filler simultaneously presses the sealing suture 4 and the auxiliary suture 5, and when the pressing pressure exceeds the strength of one of the auxiliary sutures 5 to break the auxiliary suture 5, the filling A small portion will enter the corresponding buffer space 32 from the accommodating space 23, and the corresponding connecting portion 31 will be bulged. At this time, the user can visually observe the phenomenon that the connecting portion 31 bulges. Filling the warning of excessive pressure can further reduce the filling pressure or stop the filling before the sealing seam 4 breaks to avoid damage to the sand bag.

In addition, since the end portion 22 is substantially flat, it is easy to align and the bonding effect is better when the two sand bags are combined. In addition, after the sealing suture 4 disposed at the end portion 22 is combined in the two sand bags, the two end portions 22 of the opposite portion are in a force balance state, so the sealing stitch of the two ends 22 will not be stressed, as a whole, it can reduce the potential structural weakness of the sand bag.

It should be noted that the ends of the two adjacent sandbags can be made of the same size, and the ends 22 of the two can be completely overlapped at the same time, and the connecting portions 31 can be used. Align and fix to further enhance the combination of the two.

Referring to Figures 4, 6, and 7, when two geotextile bags with joints are to be joined, one of the two methods of joining the sand bags can be joined. The first method includes The following steps 71~72.

At step 71, the connecting portions 31 of one of the sandbags are respectively coupled to the connecting portions 31 of the other sandbags.

In this embodiment, the connecting portions 31 can be joined by stitching, bonding, adding holes, and binding by using a strap, since each connecting portion 31 is broken after the respective auxiliary stitch 5 is broken. It will only begin to play the role of warning, so even if it is stitched, it will not affect the original structural strength.

At step 72, the fillings are filled with the respective sand bags.

In this way, since the sandbags of the same sand are easily aligned and unbonded when the filler is not filled, the filler is filled after the combination, and the bulk of the filler can be avoided after being filled first. A problem that is difficult to fully align.

When a plurality of geotechnical gut bags are to be stacked, since each end portion 22 of each geotechnical gut bag has a rectangular shape, each of the geotechnical gut bags will have a shape resembling a cuboid. Easy to stack, so there are no discontinuities.

Referring to Figures 4, 6, and 8, the second joining method includes the following steps 81-83.

At step 81, one of the ground sand bags is filled with the filling.

At step 82, the connecting portions 31 of the geotextile bag that have been filled with the filling are respectively coupled to the connecting portions 31 of another grit bag that has not been filled with the filling.

At step 83, the fill is filled with another ground sausage bag that has not been filled with the fill.

In this way, after filling one of the sandbags in the first place, the other sandbags that have not been filled can be unfolded and then filled, and the filling can be avoided during the filling process. The gravity of the object cannot be unfolded.

It should be noted that, in this embodiment, the bag unit 2 is sealed with a suture on the other side opposite to the end portion 22, but in other embodiments, it may be made. The same structure as the end portion 22 can achieve the same effect.

Referring to Figure 9, a second preferred embodiment of the present invention is similar to the first preferred embodiment in that:

Each connecting portion 31 has two dividing stitches 311 intersecting the sealing stitch 4, and the dividing stitches 311 divide the corresponding buffer space 32 into three compartments 321 .

The strength of the auxiliary suture 5 corresponding to the connecting portion 31 is lower than the strength of each of the dividing stitches 311 of the connecting portion 31.

The strength of the separation stitch 311 in each connecting portion 31 along the sealing seam 4 that is relatively far from the respective auxiliary suture 5 is greater than the auxiliary suture in the connecting portion 31 along the sealing suture 5. The strength of the separation stitch 311 of 5.

In use, when the pressing pressure exceeds the strength of one of the auxiliary sutures 5 to break the auxiliary suture 5, a small portion of the filler enters the adjacent compartment area 321 from the accommodating space 23 when When the squeezing pressure continues to rise, the adjacent dividing suture 311 is broken, and the strength of the separating suture 311 located outside the auxiliary suture 5 is gradually increased, so that it is equivalent to breaking at the sealing suture 4 There will be multiple warnings before to avoid damage to the sand bag.

Thus, the second preferred embodiment can achieve the same objects and effects as the first preferred embodiment described above.

Referring to Figure 10, a third preferred embodiment of the present invention is similar to the first preferred embodiment in that:

The sealing suture 4 is linear, each auxiliary suture 5 is linear, and each auxiliary suture 5 is not perpendicular to the sealing suture 4, and the end portion 22 has a trapezoidal shape, so that the The geotechnical sand sausage bag is easy to stack. The ramped surface of the end portion 22 can guide the impinging water flow upward to reduce the foundation of the water flow and to help maintain the stability of the structure.

Thus, the third preferred embodiment can achieve the same purpose and effect as the first preferred embodiment described above.

Referring to Figure 11, a fourth preferred embodiment of the present invention is similar to the first preferred embodiment in that:

The sealing suture 4 is linear, and each auxiliary suture 5 has an arc shape, and the end portion 22 has an elliptical shape.

Since the shape of the ellipse can make the stress distribution received during filling, the strength of the sand bag is improved.

Thus, the fourth preferred embodiment can achieve the same objects and effects as the first preferred embodiment described above.

Referring to Figure 12, a fifth preferred embodiment of the present invention is similar to the second preferred embodiment in that:

The sealing suture 4 is linear, each auxiliary suture 5 is a two-segment straight line bent away from the other auxiliary suture 5, each connecting portion 31 has two and the auxiliary suture 5 and the sealing seam The line 4 intersects the split stitches 311 which divide the corresponding buffer space 32 into three compartments 321 which are in the shape of a hexagon.

Since the shape of the hexagon can make the stress distribution received when filling, the strength of the sand bag is improved.

In the present embodiment, each of the auxiliary sutures 5 and the corresponding two separate sutures 311 are formed by directly sewing two intersecting sutures on the bag body unit 2 and the auxiliary unit 3 which are integrally formed.

Thus, the fifth preferred embodiment can achieve the same objects and effects as the second preferred embodiment described above.

In summary, by the arrangement of the connecting portions 31 and the auxiliary sutures 5, when the filling pressure is too large, the auxiliary sutures 5 can be broken first and the corresponding connecting portions 31 can be bulged. Therefore, the user can obtain early warning after the warning is obtained, and the damage of the sand bag is avoided. Further, since the end portion 22 is substantially flat, the sealing stitch 4 disposed at the end portion 22 is squeezed. The pressure will be relatively small and therefore less susceptible to damage, so the object of the invention can be achieved.
