Description

Technical Field

[0001] The utility model belongs to the technical field of engineering construction, in particular to a geotechnical mold bag. Background Art

[0002] As a construction material, geobags are widely used in dam slope protection, revetment, harbor and dock protection projects in rivers, lakes and seas. In recent years, geobags have also been frequently used in construction projects that use soft soil, silt or construction waste as fill materials.

[0003] Traditional geobags are large, continuous bags made of two layers of geotextile fabric. The bags are filled with concrete, cement mortar, drained soft soil, or silt, and solidify into a fill material. The two layers are connected by a nylon rope of a certain length to control the thickness of the fill material. Although traditional geobags have a certain degree of permeability, allowing excess water to seep through the fabric voids after filling, because the fabric voids are located on the surface of the geobag, the outer fill material near the center of the geobag solidifies earlier than the inner fill material near the center. As the outer fill material solidifies, the moisture contained in the inner fill material becomes increasingly difficult to drain, affecting the overall curing efficiency. Therefore, the moisture content of the fill material must be controlled before filling. For soft soil and silt with high moisture content, drainage is usually required before filling, which increases the construction period.

[0004] Therefore, how to provide a geotextile bag suitable for high-water content fillings is a technical problem that urgently needs to be solved. Utility Model Content

[0005] In response to the above technical problems, the present invention provides a geotextile mold bag with a drainage channel inside, which can ensure the drainage effect of the internal filling material, is suitable for filling filling materials with high water content, and can effectively shorten the filling construction period.

[0006] The utility model provides a geotextile bag, comprising:

[0007] The bag body is surrounded by a mold bag cloth, and the mold bag cloth has a first drainage hole communicating the inner space of the bag body with the outer space;

[0008] Multiple drainage ribs are staggeredly arranged in the bag body, and the ends of the drainage ribs in the length direction are connected to the bag body; a drainage channel is opened in the drainage rib and penetrates the drainage rib along the length direction of the drainage rib, and a plurality of second drainage holes connected to the drainage channel are opened on the periphery of the drainage rib. The drainage channel is provided with drainage outlets at the end faces of both ends in the length direction of the drainage rib to connect with the first drainage holes of the bag body at the connection between the drainage rib and the bag body.

[0009] In some embodiments, the bag is in the shape of a tube with an open top.

[0010] In some embodiments, the drainage ribs include a plurality of transverse drainage ribs arranged along the transverse direction of the bag body and a plurality of longitudinal drainage ribs arranged along the longitudinal direction of the bag body. The two ends of the transverse drainage ribs are respectively connected to the two side surfaces of the bag body that are opposite to each other in the transverse direction, and the two ends of the longitudinal drainage ribs are respectively connected to the two side surfaces of the bag body that are opposite to each other in the longitudinal direction. The plurality of transverse drainage ribs and the plurality of longitudinal drainage ribs are staggered in the bag body.

[0011] In some embodiments, the drainage ribs also include a plurality of vertical drainage ribs arranged vertically along the bag body, and the plurality of vertical drainage ribs are distributed in the bag body and staggered with the transverse drainage ribs and the longitudinal drainage ribs; the upper part of the vertical drainage ribs intersects and connects with the transverse drainage ribs or the longitudinal drainage ribs, and the bottom end of the vertical drainage ribs is connected to the bottom surface of the bag body.

[0012] In some embodiments, the drainage ribs further include a plurality of oblique drainage ribs, which are arranged obliquely relative to the transverse drainage ribs and the longitudinal drainage ribs, and the two ends of the oblique drainage ribs are respectively connected to two obliquely opposite points of the bag body.

[0013] In some embodiments, the drainage rib is made of a flexible material.

Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features.

[0038] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0039] As attached Figure 1 and Figure 2 As shown, in an exemplary embodiment of the geotextile mold bag of the present invention, the geotextile mold bag includes a bag body 1 and a plurality of drainage ribs 2; the bag body 1 is surrounded by a mold bag cloth, and the mold bag cloth has a first drainage pore a connecting the interior space and the exterior space of the bag body 1; the plurality of drainage ribs 2 are staggeredly arranged in the bag body 1, and the ends of the drainage ribs 2 in the longitudinal direction are connected to the bag body 1; the drainage ribs 2 are provided with drainage channels c that pass through the drainage ribs 2 along the longitudinal direction, and the outer periphery of the drainage ribs 2 is provided with a plurality of second drainage pores b that are connected to the drainage channels c. The drainage channels c are provided with drainage ports d at both end surfaces of the drainage ribs 2 in the longitudinal direction, so as to connect the first drainage pores a of the bag body 1 at the connection between the drainage ribs 2 and the bag body 1. It should be noted that the size of the second drainage pores b is smaller than that of soft soil particles to prevent soft soil particles from entering the drainage channels c and blocking the drainage channels c.

[0040] The above-mentioned geotechnical mold bag has a plurality of drainage ribs 2 staggeredly arranged inside its bag body 1. When filling a high-water-content filler, a large amount of water contained in the filler can flow into the drainage channel c through the second drainage pores b of the drainage ribs 2, and be guided from the drainage channel c to the bag body 1 through the drainage port d, and seep out from the first drainage pores a of the bag body 1, achieving drainage while the filler is being filled. This can meet the direct filling requirements of the high-water-content filler without the need to drain the high-water-content filler in advance, and can effectively shorten the filling construction period. Moreover, the above-mentioned geotechnical mold bag, through the drainage ribs 2 arranged inside, makes the drainage of the internal filler unaffected by the solidification of the external filler, and can ensure the drainage effect of the internal filler. In addition, the drainage ribs 2 are arranged inside the bag body 1 of the above-mentioned geotechnical mold bag, which can strengthen the structural strength of the entire geotechnical mold bag.

[0041] In order to facilitate the filling of fillings, such as Figure 1 As shown, the bag body 1 is cylindrical with an open top. During filling, the bag is filled directly from the top opening, allowing direct docking with transportation equipment and high-intensity filling rates of up to several hundred cubic meters per hour (for example, direct dumping from vehicles, or direct dumping or blow-filling from water dredging equipment). This significantly increases the filling speed of the mold bag compared to traditional processes.

[0042] In order to facilitate the full drainage of internal fillings, such as Figure 1 As shown, the drainage ribs 2 include a plurality of transverse drainage ribs 21 arranged transversely along the bag body 1 and a plurality of longitudinal drainage ribs 22 arranged longitudinally along the bag body 1. The two ends of the transverse drainage ribs 21 are respectively connected to the two side surfaces of the bag body 1 arranged opposite to each other in the transverse direction, and the two ends of the longitudinal drainage ribs 22 are respectively connected to the two side surfaces of the bag body 1 arranged opposite to each other in the longitudinal direction. The plurality of transverse drainage ribs 21 and the plurality of longitudinal drainage ribs 22 are staggered in the bag body 1.

[0043] Further, such as Figure 1 As shown, the drainage ribs 2 also include a plurality of vertical drainage ribs 23 arranged vertically along the bag body 1. The plurality of vertical drainage ribs 23 are distributed in the bag body 1 and are staggered with the transverse drainage ribs 21 and the longitudinal drainage ribs 22. The upper part of the vertical drainage ribs 23 intersects and connects with the transverse drainage ribs 21 or the longitudinal drainage ribs 22, and the bottom end of the vertical drainage ribs 23 is connected to the bottom surface of the bag body 1.

[0044] In order to further realize the omnidirectional drainage of the internal filling, in the second embodiment of the present utility model, as Figure 3 As shown, the drainage ribs 2 also include multiple oblique drainage ribs 24, which are inclined relative to the transverse drainage ribs 21 and the longitudinal drainage ribs 22. The two ends of the oblique drainage ribs 24 are respectively connected to two obliquely opposite points of the bag body 1.

[0045] It should also be noted that the drainage ribs 2 are preferably made of flexible materials, such as rubber, resin, fiber or metal, etc. When a high-water content filler is poured into the mold bag, the bag body 1 expands outwards and the drainage ribs 2 are tightened, limiting the amount of expansion of the bag body 1.

[0046] In some embodiments, in order to facilitate the maintenance of the expanded state of the bag body 1 when filling the filler, as shown in FIG. Figure 4 and Figure 5 As shown, a suspending member 3 for suspending the bag 1 is provided on the outer periphery of the top opening of the bag 1. When filling, the bag 1 is lifted by the suspending member 3 so that the top opening of the bag 1 is always facing upward and remains in position to prevent the bag 1 from being pulled down by the gravity of the filling during filling, which would affect the filling process.

[0047] Specifically, such as Figure 4 As shown, the suspending member 3 includes a first cloth cover 31 symmetrically connected to opposite edges of the top opening of the bag body 1. The axis of the first cloth cover 31 is arranged in the horizontal or vertical direction of the top opening of the bag body 1. When filling, the first cloth cover 31 is placed over the transverse support member to prop open the top opening of the bag body 1 and keep it open. At the same time, the first cloth cover 31 withstands the downward pull of the bag body 1 during filling, maintaining the position of the top opening of the bag body 1 for easy filling.

[0048] Furthermore, in some embodiments, Figure 5 As shown, the suspending member 3 further includes a plurality of second cloth sleeves 32 connected to the outer periphery of the bag body 1. The axis direction of the second cloth sleeves 32 is arranged along the vertical direction of the bag body 1. The plurality of second cloth sleeves 32 are distributed outside the bag body 1 and are arranged near the top opening of the bag body 1. When filling with high-water content fillings, the second cloth sleeves 32 are placed outside the vertical support member to utilize the second cloth sleeves 32 to withstand the impact force of the water flow on the bag body 1, thereby maintaining the position of the bag body 1 and preventing the bag body 1 from shaking significantly.

[0049] In addition, it should be noted that the mold bag cloth is preferably made of fabric, and the gaps between the fabrics generated during weaving serve as the first drainage pores a. Figure 6 As shown, the method for making the geotextile mold bag is as follows: a mold bag cloth is connected around a vertical axis to form a cylindrical shape, which serves as a vertical mold bag cloth 11; another piece of mold bag cloth is unfolded in the horizontal direction, which serves as a transverse mold bag cloth 12; the edge of the transverse mold bag cloth 12 is connected to the lower edge of the vertical mold bag cloth 11 to form a bag body 1; the drainage rib 2 is placed in the bag body 1, and the end of the drainage rib 2 is connected to the bag body 1 to form a geotextile mold bag.

[0050] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0051] The above embodiments are only used to illustrate the technical solution of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention. They should all be included in the scope of the technical solution for which protection is requested in the present invention.
