Description

Technical Field

[0001] This utility model relates to the field of mine backfilling technology, and in particular to a self-standing reverse filter high-strength backfilling mold bag. Background Technology

[0002] Traditional retaining walls used for underground mine backfilling mainly include ordinary wooden retaining walls, brick retaining walls, concrete retaining walls, and flexible retaining walls. These retaining walls have complex construction processes, long construction periods, and expose workers to the goaf for extended periods, posing a high risk. The high cost of retaining wall materials and labor also increases backfilling costs. Currently, some retaining walls using geotextile bags for backfilling have emerged. However, these geotextile bags are made of flexible membrane material and have poor self-supporting properties after filling. They are fixed and supported by binding straps on the geotextile bags, but the point contact between the straps and the geotextile bags leads to stress concentration after filling, making them prone to tearing. Furthermore, the geotextile bags between the two binding points are prone to collapse after grouting. After filling, the solidified geotextile bag filling body has an irregular shape, poor sealing function, and is difficult to control during the filling process. The second method involves completely enclosing the geotextile bags within a sturdy support space. However, this method consumes a lot of materials and requires a large amount of support work. The third method involves sewing the support sleeves into the molded bags. However, this method requires all the molded bags to be placed on the support beforehand and then the support to be fixed. It requires accurate calculation of the number and size of the molded bags, has poor adjustability, and involves laying them first and then filling them layer by layer from bottom to top. This method is difficult to construct, and the support is wrapped in the filled molded bag body and cannot be recycled. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a self-standing reverse filter high-strength filling mold bag, which is suitable for the construction of mine filling retaining walls.

[0004] The technical solution of this utility model is as follows:

[0005] A self-standing reverse filter high-strength filling molded bag includes a filling molded bag body with filling cuffs and / or process pipe cuffs. The filling molded bag body has a plurality of sleeve channels for threading rods on at least one side. The sleeve channels include transversely arranged transverse rod sleeve channels and / or vertically arranged vertical rod sleeve channels.

[0006] In a further technical solution, the number of the transverse rod sleeves is ≥1.

[0007] In a further technical solution, the transverse rod sleeve channel is divided into at least one segment, and a transverse rod is respectively inserted in each segment of the transverse rod sleeve channel. The total length of the transverse rods in the transverse rod sleeve channel is greater than or equal to the maximum width of the layer position of the molded bag, so as to adapt to different cross-sectional size requirements.

[0008] In a further technical solution, the length of a single transverse rod is less than or equal to the width of the molded bag body, the length of a single transverse rod is less than or equal to the maximum width of the molded bag layering position, and the width of the molded bag body is greater than or equal to the maximum width of the molded bag layering position.

[0009] In a further technical solution, the rod is a rod-shaped object such as a steel pipe, reinforcing bar, or round steel with a certain rigidity, which can be recycled after the filling slurry in the filling mold bag has been cured to meet the design requirements.

[0010] In a further technical solution, the number of vertical rod sleeves is ≥1.

[0011] In a further technical solution, the filling bag body has a double-layer structure, with the outer layer being woven geotextile and the inner layer being knitted geotextile.

[0012] In a further technical solution, a pair of opposite sides of the filling mold bag body are provided with tie-up reinforcing cuffs for binding tie-up reinforcing ribs.

[0013] In a further technical solution, a steel mesh is fixed between the horizontal or vertical members.

[0014] In a further technical solution, the end of the tension reinforcing rib is a ring, and the outer diameter of the rod is smaller than the inner diameter of the ring, so that the transverse rod can pass through the ring. After the filling bag is filled, the tension reinforcing rib provides tension and also plays the role of strengthening the retaining wall.

[0015] In a further technical solution, the tension reinforcing bar is made of steel bars and rods.

[0016] The beneficial effects of this utility model are:

[0017] This utility model discloses a self-supporting, high-strength, reverse-filtering filling formwork bag. It adopts a rod-supported structure, ensuring robustness and easy assembly. The bag stands upright after filling. The filling formwork bag features a double-layer structure: the outer woven geotextile layer provides strength support, while the inner knitted geotextile layer acts as a filter, significantly improving the bag's strength. The structural members used can be recycled after the filling slurry inside the bag has cured to the design strength, making it economical and environmentally friendly. It is suitable for mine filling retaining wall construction, engineering enclosure and isolation, and the construction of structures requiring support. The members employ a prefabricated structural design. Members inserted into the sleeve can be fixed to columns or horizontal supports using member fasteners. Horizontal and vertical members can be assembled into a grid frame to enhance self-support. Force is transmitted through linear members and the filling formwork sleeve, resulting in more even stress distribution. Tension between the members ensures a more regular bag shape after filling.

[0029] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0030] Example 1:

[0031] A self-standing high-strength filling molded bag for reverse filter, such as Figure 1As shown, the filling mold bag body 10 includes a filling sleeve 20 and / or a process pipe sleeve. The sides of the filling mold bag body 10 are provided with several sleeve channels for threading rods. The rods are made of steel pipes, reinforcing bars, or round steel rods with a certain rigidity and can be recycled after the filling slurry inside the filling mold bag has cured to the design requirements. The sleeve channels include transversely arranged transverse rod sleeve channels 30 and / or vertically arranged vertical rod sleeve channels. The number of transverse rod sleeve channels 30 is ≥1, and each transverse rod sleeve channel 30 is divided into at least one segment. Each segment of the transverse rod sleeve channel 30 contains one transverse rod 40. The total length of all transverse rods 40 within the same transverse rod sleeve channel 30 is ≥ the maximum width of the mold bag's layering position to accommodate different cross-sectional size requirements. Furthermore, the length of a single transverse rod 40 is ≤ the width of the mold bag body, the length of a single transverse rod 40 is ≤ the maximum width of the mold bag's layering position, and the width of the mold bag body is ≥ the maximum width of the mold bag's layering position. The number of vertical rod sleeves is ≥1. The vertical rods 50 can make the horizontal rods 40 on one side of the filling mold bag body 10 located on a vertical surface, so that after the filling slurry is injected into the filling mold bag body 10, the side of the filling mold bag body 10 still remains vertical, and the height of the mold bag after filling with filling slurry is ≥ the height difference between the uppermost horizontal rod 40 and the lowermost horizontal rod 40.

[0032] In this embodiment, the filling bag body 10 has a double-layer structure. The outer layer is a woven geotextile, which serves as a strength support, and the inner layer is a knitted geotextile, which serves as a filter. The two layers are sewn together at the designed spacing to form a double-layer fabric, and then processed into a filling bag according to the designed shape.

[0033] The self-supporting high-strength filter filling mold bag of this embodiment can be specifically designed as a one-sided support type filling mold bag, as shown below. Figures 2-5 As shown, it can also be assembled with a double-sided support type filling mold bag, as detailed below. Figures 6-8 As shown.

[0034] In another embodiment, a steel mesh is fixed between the horizontal or vertical members.

[0035] In another embodiment, such as Figure 9 As shown, a set of opposite sides of the filling bag body 10 are provided with tie-up reinforcing ribs 60 for binding tie-up reinforcing ribs 60. The end of the tie-up reinforcing rib 60 is a ring, and the outer diameter of the rod is smaller than the inner diameter of the ring, so that the transverse rod 40 can pass through the ring. After the filling bag is filled, the tie-up reinforcing rib 60 provides tension and also plays the role of reinforcing the retaining wall.

[0036] In this embodiment, the tension rib 60 is made of steel bars and rods.

[0037] Example 2:

[0038] The assembly process of a self-supporting high-strength filling molded filter bag is as follows:

[0039] A transverse rod sleeve is sewn on one side of the filling mold bag. The number of transverse rod sleeves is ≥1. After the filling mold bag is laid, the transverse rod can be passed through it. To facilitate the laying of the filling mold bag, the length of the transverse rod is ≤ the width of the mold bag, and the length of the transverse rod is ≤ the maximum width of the layer position of the mold bag.

[0040] The transverse bar channel is divided into ≥1 segment, with one transverse bar inserted into each segment. The sum of the lengths of the transverse bars is greater than or equal to the maximum width of the layered position of the molded bag, to accommodate different cross-sectional size requirements.

[0041] In addition, vertical rod sleeves are sewn along the width of the filling mold bag, with ≥1 vertical rod sleeve. After the filling mold bag is laid, the vertical rods can be inserted to fix the horizontal rods, so that the horizontal rods on one side of the filling mold bag are in a vertical position. This ensures that after the filling slurry is injected into the filling mold bag, the side of the filling mold bag remains vertical, and the height of the mold bag after filling with slurry is ≥ the height difference between the uppermost and lowermost horizontal rods. Furthermore, to improve the self-supporting strength of the filling mold bag retaining wall, the two ends of the vertical rods are fixed to the upper and lower walls at the construction location of the filling retaining wall.

[0042] The left and right sides of the filling bag are sewn with tension reinforcing rib cuffs. The tension reinforcing ribs can pass through the tension reinforcing rib cuffs and the tension reinforcing rib cuffs are tied to the tension reinforcing ribs. The two ends of the tension reinforcing ribs are rings. The outer diameter of the horizontal member is smaller than the inner diameter of the ring. The horizontal member can pass through the ring. After the filling bag is filled, the tension reinforcing ribs provide tension and also play the role of reinforcing the retaining wall.

[0043] The width of the filling mold bag is greater than or equal to the maximum width of the layered position of the mold bag in the retaining wall section.

[0044] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
