Description

Technical Field

[0001] This utility model belongs to the field of paving construction technology, and in particular relates to a flexible paving template for coal mines. Background Technology

[0002] In traditional coal mine roadway hardening construction, channel steel or profiles are often used for formwork. Because the formwork materials occupy a large space and are heavy, this increases the number of transport trips by material transport vehicles, leading to increased energy consumption. Before formwork erection, surveying and setting out, road leveling, and clearing of stones are required. After formwork erection, paving and road leveling are completed, and the formwork is removed after the road surface hardens. The surveying and setting out, and the road leveling before paving, are labor-intensive, and formwork erection is difficult on winding and uneven sections. The subsequent removal of formwork after road surface hardening places high demands on construction personnel, increasing construction costs, the number of workers, and workload. Solving these problems has become a technical challenge in this field. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a flexible paving template for coal mines, specifically solving the problems through the following technical means:

[0004] A flexible paving template for coal mines, characterized in that it comprises multiple interconnected flexible fabric bags, wherein: the flexible fabric bag is a hollow bag body with an isosceles trapezoidal cross-section; a casting hole is provided at the top of the flexible fabric bag, and the casting hole extends inward to form an inward flange; a central support pipe is vertically installed at the center of the flexible fabric bag; side support strips are symmetrically arranged on both sides of the flexible fabric bag; a horizontal support strip is provided at the top of the flexible fabric bag; the side support strips and the horizontal support strips are staggered; reinforcing bars are inserted into through holes in the central support pipe and the side support strips to fix the flexible fabric bags to the road surface; the horizontal support strips are used to connect adjacent flexible fabric bags.

[0005] Preferably, the assembly also includes clamps, sealing flanges, casting pipes, and bolts, wherein: the sealing flange is installed in the casting hole; the clamp connects the inner flange of the casting hole to the body of the sealing flange; multiple bottom bolt holes are symmetrically arranged on the sealing flange; multiple top bolt holes are symmetrically arranged on the base of the casting pipe; and the bolts connect the bottom bolt holes and the top bolt holes, thus connecting the sealing flange and the casting pipe into one unit.

[0006] Preferably, the side support strips and the cross support strips are perforated semi-circular structures.

[0007] Preferably, it also includes a U-shaped connecting piece, which consists of two parallel semi-circular bars and an end connecting arm. The U-shaped connecting piece can be inserted into adjacent transverse support strips to achieve a fixed connection between adjacent flexible fabric bags.

[0008] Preferably, multiple interconnected flexible cloth bags are arranged in parallel on the road surface, forming a discharge zone between the flexible cloth bags. After the concrete is poured into the discharge zone, it is smoothed by the top roller.

[0009] The flexible paving template for coal mines of this utility model has the following beneficial effects:

[0010] This flexible paving formwork uses flexible fabric bags, which are high-strength and have good water permeability. They ensure sufficient strength under concrete pressure while possessing excellent flexibility, greatly simplifying construction operations. Unlike traditional formwork, there's no need to consider reuse issues. It can also closely conform to curved and uneven roads, requiring less pre-formwork site leveling and lower technical skill levels for construction workers, reducing construction quality problems caused by human factors. Furthermore, it occupies little space, is lightweight, eliminates the need for secondary formwork removal, and has low requirements for road surface flatness before paving. This significantly simplifies construction steps, reduces the labor intensity of construction workers, and decreases the number of workers required, effectively achieving cost reduction and efficiency improvement.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0020] The present invention will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1 to 6 As shown, the flexible paving template for coal mines includes multiple interconnected flexible duct bags 1. In the figure: the flexible duct bag 1 is a hollow bag body with an isosceles trapezoidal cross-section. The top of the flexible duct bag 1 has a pouring hole 101, which extends inward to form an inward flange. A central support pipe 105 is vertically installed at the center of the flexible duct bag 1. Side support strips 102 are symmetrically arranged on both sides of the flexible duct bag 1. A horizontal support strip 103 is arranged at the top of the flexible duct bag 1. The side support strips 102 and the horizontal support strips 103 are staggered. Reinforcing bars are inserted into the through holes in the central support pipe 105 and the side support strips 102 to fix the flexible duct bag 1 to the road surface 6. The horizontal support strip 103 is used to connect adjacent flexible duct bags 1.

[0022] In this embodiment, the side support strip 102 and the transverse support strip 103 are perforated semi-circular structures. In addition, a U-shaped connecting piece 104 is also included. The U-shaped connecting piece 104 is composed of two parallel semi-circular bars and an end connecting arm. The U-shaped connecting piece 104 can be inserted into adjacent transverse support strips 103 to achieve a fixed connection between adjacent flexible fabric bags 1.

[0023] Specifically, this flexible paving formwork uses flexible fabric bags. These bags are high-strength and have good water permeability, ensuring sufficient strength under concrete pressure while possessing excellent flexibility. This greatly simplifies construction operations, eliminating the need for reuse considerations like traditional formwork. It also fits snugly against uneven roads, reducing the requirements for site leveling before formwork erection and the technical skills of construction workers. This reduces construction quality issues caused by human factors. Furthermore, it occupies little space, is lightweight, eliminates the need for secondary formwork removal, and has low requirements for road surface flatness before paving. This significantly simplifies construction steps, reduces the labor intensity of construction workers, and decreases the number of workers required, effectively achieving cost reduction and efficiency improvement.

[0024] The figure also includes clamp 2, sealing flange 3, casting pipe 4 and bolt 5. The sealing flange 3 is installed in the casting hole 101. The clamp 2 connects the inner flange of the casting hole 101 to the body of the sealing flange 3. Multiple bottom bolt holes 301 are symmetrically arranged on the sealing flange 3. Multiple top bolt holes 401 are symmetrically arranged on the base of the casting pipe 4. The bolt 5 connects the bottom bolt holes 301 and the top bolt holes 401, connecting the sealing flange 3 and the casting pipe 4 into one unit.

[0025] It should be noted that the pouring pipe 4 is detachably connected to the sealing flange 3, and the sealing flange 3 is detachably installed on the pouring hole 101 by means of clamp 2. The above structure can be flexibly adjusted in size to adapt to different specifications of templates and laying requirements.

[0026] In practical applications, multiple interconnected flexible formwork bags 1 are arranged parallel to each other on the road surface 6, forming a discharge area 7 between the flexible formwork bags 1. After the concrete is poured into the discharge area 7, it is smoothed by the top roller 8. Specifically, the formwork is laid based on the boundary lines and elevation control points determined by the surveying and setting out. Starting from the beginning of the construction area, the flexible formwork bags are unfolded sequentially along the marked lines. Depending on the actual shape of the site, such as curves and slope changes, the formwork can be moderately bent and adjusted due to its good flexibility. The flexible formwork can be fixed simply by inserting the reinforcing bars into the holes of the formwork reinforcement bars and inserting them into the leveled road surface. At the connection of two single flexible formwork bags, the reinforcing bars inserted into the holes of the formwork reinforcement bars are simply wrapped together with steel wire, eliminating the need for complex on-site splicing as with traditional formwork.

[0027] It should be further explained that the concrete pump outlet is connected to the pouring port, allowing concrete to be delivered into the flexible formwork. After pouring, the pouring port is removed, and the concrete at the sealing flange is leveled. After drying and the reinforcing steel is removed, the road surface can be paved. After the formwork is erected and the reinforcing steel is removed on both sides of the road, the concrete pumping equipment pours the concrete into the unloading area, where construction workers use rollers to level the road surface. Uneven areas can be manually filled. The above describes the implementation method of using multi-section flexible formwork to replace traditional formwork in coal mine road hardening construction, reducing costs, increasing efficiency, and reducing the labor intensity of construction workers.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
