[0019] The following description, in conjunction with the accompanying drawings, describes the precast soft-pack concrete wall suitable for use in roadway retaining.

[0020] In Embodiment 1 of this application, as Figures 1 to 3As shown, a precast soft-pack concrete wall suitable for use in roadway retaining structures includes a soft-pack 1, a soft-pack body 11, a top beam inclined steel wire rope 12, a soft-pack limiting steel wire rope 13, a concrete filling port 2, a concrete filling pipe fixing protrusion 21, a filling port pipe 22, a telescopic connecting rod 23, a sealing plate 24, a top ring 25, a top ring bracket 26, an external bracket 3, a top beam 31, an external upright plate 32, a pre-drilled hole for the filling port 33, a connecting sleeve 34, a connecting pin 35, an external upright plate connecting steel wire rope 36, and a supporting connecting rod 37. Two sets of external brackets 3 are installed at the front and rear of the soft-pack 1, respectively. The soft-pack 1 also includes a soft-pack body 11 and a soft-pack limiting steel wire rope 13. The soft-pack body 11 is secured to the outside of the external brackets 3 by straps or fabric. The soft-pack body 11 contains multiple external upright plates 32 sewn onto the outside of the soft-pack body 11. The steel connector at the end of the limiting steel wire rope 13 is connected to the external upright plate 32 by screws. The two external upright plates 32 are connected by the external upright plate connecting steel wire rope 36. The steel connector at one end of the top beam inclined steel wire rope 12 inside the soft package body 11 is connected to the top of the external upright plate 32 by screws, and the other end is connected to the installation position of the top beam 31 at the top of the soft package body 11 by screws. The soft package body 11 is provided with a cloth sleeve inserted into the top beam 31. The concrete filling port 2 passes through the reserved hole 33 of the filling port and is connected to the soft package body 11. The connecting sleeve 34 and connecting pin 35 are fixedly installed on both sides of the outer side of the external support 3 to facilitate the connection of the equipment end to end and further improve the support strength. The middle section of the soft package limiting steel wire rope 13 is tied with the built-in steel bar 14, and the width of the built-in steel bar 14 is the same as that of the external upright plate 32.

[0021] The utility model patent CN220539686U describes a concrete wall shaping device. This device uses a support plate set on one side of a flexible mold bag. The support plate has a guide structure, and guide components are movably mounted on the guide structure. The guide components are connected to the support column via a connecting component. The support column supports the support plate through the connecting component and the guide component, thereby shaping the concrete wall. However, this patent has a complex structure with many components, resulting in a large workload during installation. In addition, most components cannot be folded, leading to low transportation efficiency. In contrast, this invention replaces the traditional mesh plate with multiple external upright plates 32 and connecting steel wire ropes 36 for connecting the external upright plates. Combined with the top beam inclined steel wire rope 12 and the flexible package limiting steel wire rope 13 built into the flexible package body 11, and its matching top beam 31, the entire flexible package can be folded, allowing for convenient and quick transportation to the construction site and rapid unfolding.

[0022] This second embodiment is basically the same in structure as the first embodiment, the difference being that, as Figure 4As shown, the concrete filling port 2 includes a concrete filling pipe fixing protrusion 21 and a top ring bracket 26. The filling port pipe 22 is fixedly installed on the soft package body 11 by a flange or adhesive. Multiple recesses are opened at the rear of the filling port pipe 22, and a spring-loaded telescopic connecting rod 23 is installed inside each recess. A sealing plate 24 is fixedly connected to the outer end of the telescopic connecting rod 23. A top ring 25 is installed on the side of the sealing plate 24 facing the filling port pipe 22 via the top ring bracket 26. The concrete filling pipe fixing protrusion 21 is installed on the protruding part outside the filling port pipe 22. The automatically sealing concrete filling port 2 ensures a smooth and aesthetically pleasing wall surface and prevents concrete spillage. The sealing plate 24 is covered with rubber, which further improves the sealing performance and prevents incomplete sealing when concrete remains on the sealing plate 24 of the filling port pipe 22.

[0023] To further optimize the working efficiency of this application and enable the soft package to stand upright without the addition of concrete, a supporting connecting rod 37 is installed between the front and rear external supports 3 of the soft package 1 via a connector. To further improve the strength of the soft package 1, the outer layer of the soft package body 11 is canvas, and the sides and bottom of the canvas are provided with inner linings, which are thermoplastic polyurethane film or high-density polyethylene film.

[0024] When in use, it is suitable for the installation of precast soft-pack concrete walls along the goaf, and the equipment can then be used to add concrete.

[0025] When this utility model is used, its specific operation is as follows:

[0026] During transportation, the equipment is folded. After transportation to the designated location, the soft package 1 is unfolded. The external support 3 outside the soft package 1 provides support. Then, the external supports 3 at the front and rear of the soft package body 11 are connected by the support connecting rod 37 to provide support. The top beam inclined steel wire rope 12 and the soft package limiting steel wire rope 13 provide limiting. Then, the connecting pin 35 of the external support 3 of the next precast concrete wall soft package is inserted into the connecting sleeve 34 of the previous precast concrete wall soft package, so that multiple precast concrete wall soft packages are connected end to end. When unfolded, the soft package limiting steel wire rope 13 makes the internal reinforcing steel 14 vertical. After installation, concrete can be injected.

[0027] When injecting concrete, the concrete pipe is inserted into the injection port pipe 22. After insertion, the end of the pipe presses against the top ring 25. The top ring 25 drives the sealing plate 24 through the top ring bracket 26. The sealing plate 24 causes the spring of the telescopic connecting rod 23 to be stretched. At this time, the sealing plate 24 disengages from the injection port pipe 22, and the concrete begins to be injected. The continuously flowing concrete supports the soft package body 11 and makes the upper part of the soft package body 11 fit against the top plate. Due to the action of the top beam inclined steel wire rope 12 and the top beam 31, the upper part of the soft package body 11 can still be maintained with only a small amount of protrusion. The built-in steel bar 14 is also poured into the soft package body 11 to ensure sufficient overall strength. After the pouring is completed, the pipe is withdrawn, the spring of the telescopic connecting rod 23 retracts, and drives the sealing plate 24 to re-close the injection port pipe 22.

[0028] Both the top beam inclined steel wire rope 12 and the soft package limiting steel wire rope 13 have connecting blocks welded to their ends. The top of each connecting block has a screw hole, and the surface of the outer vertical plate 32 also has corresponding holes. Screws pass through these holes and are screwed into the screw holes of the top beam inclined steel wire rope 12 or the soft package limiting steel wire rope 13, connecting the soft package 1 and the outer support 3 into a single unit. During concrete pouring, the outer support 3 externally limits the entire soft package 1, ensuring a flat and aesthetically pleasing surface.

[0029] In summary, the precast soft-pack concrete wall panels of this utility model embodiment, applicable to tunnel-side clearance, replace the traditional mesh panels with multiple external vertical panels 32 and connecting steel wire ropes 36 for connecting the external vertical panels. Combined with the top beam inclined steel wire rope 12 and soft-pack limiting steel wire rope 13 built into the soft-pack body 11, the soft-pack can be folded as a whole, which can be conveniently and quickly transported to the construction site and quickly unfolded. At the same time, with the help of the automatically sealing concrete filling port 2, the wall surface can be ensured to be flat and beautiful and concrete spillage can be prevented.
