Description

Technical Field

[0001] The present invention relates to the technical field of infrastructure construction, in particular to the technical field of special-shaped steel cage weaving in anti-seepage walls in anti-seepage wall casting construction technology, and specifically to a special-shaped steel cage weaving system and method. Background Art

[0002] The construction process of an anti-seepage wall primarily involves site preparation, guide wall construction, slot excavation, slurry wall protection, wall pouring, and quality inspection. Pre-construction requires site cleanup and surveying and layout. Subsequently, a guide wall is cast along the wall axis to secure the slot position and support the equipment. Slots are excavated in sections using equipment such as impact drills, hydraulic grabs, or slot saws. Slurry is circulated during the process to maintain the stability of the hole walls and prevent collapse. After the slots are completed, sediment is removed from the bottom of the hole using a sand pump or suction method, and fresh slurry is replaced. The wall is typically constructed of concrete or plastic concrete, poured continuously from bottom to top using a conduit method. Adjacent slot sections are connected using sleeves or flush joints to ensure continuous anti-seepage. After pouring, the wall is inspected and tested for integrity, impermeability, and overlap quality through core drilling, water injection testing, or geophysical exploration. Finally, the guide wall is backfilled and the surface restored to form a complete underground anti-seepage barrier. Strict control of verticality, slot spacing, and material mix is required throughout the construction process to ensure the integrity and durability of the anti-seepage wall.

[0003] Due to different geological conditions, different continuous wall structure designs are used, but the construction process is basically the same. According to the different locations of the continuous wall, it can be divided into node piles and continuous walls. Node piles generally refer to the convergence points of continuous walls in different directions in the anti-seepage wall. In actual construction, the node pile holes are generally excavated first, and then the node piles are cast. After the node piles solidify, the continuous wall trough is excavated, and finally the continuous wall is cast. Node piles are the key work of the entire anti-seepage wall construction. Due to different geological designs of continuous walls, there are node piles with different cross-sectional shapes at the node pile positions, so the steel cages of the node piles will also be different, such as cross-shaped, T-shaped, etc. It is formally based on a non-standard type and needs to be designed according to special geology. Therefore, the corresponding steel cage shapes and sizes are not available, and there are difficulties in the preparation of the steel cage. In the existing technology, two methods are generally used on the construction site: one is to make the tooling of special-shaped steel cages on site, manually arrange the steel bars according to the tooling, and then tie or weld them to fix them. After the basic shape is finalized, the tooling is taken out and then reinforced and fixed. The advantage of this method is that the manufactured steel cages are highly uniform. The disadvantage is that the cost investment is large, and the degree of mechanization and automation that can be achieved is low. The tooling is customized based on specific projects, and the subsequent reuse rate is low. The other is manual welding without tooling, which is to manually weld and fix the steel cages during weaving. While weaving and fixing, the size of the steel cages is measured. This method is less efficient than the first method, but the cost investment will be less. There is no need to make customized tooling, but the labor investment is large, and the steel cages are not uniform. When the steel cage units are subsequently combined or docked, it is easy to fail to dock and there are problems of misalignment. Summary of the Invention

[0047] Example 1:

[0048] See the instructions attached Figures 1-6 The illustrated system for weaving a special-shaped steel bar cage includes a feeding mechanism 10 for axially conveying bundles of steel bars to a sawing mechanism 20, which saws the steel bars according to a preset length; a feeding mechanism 30 for conveying individual steel bars, which have been sawn to the preset length, one by one to a feeding mechanism 80. A threading mechanism 40 and a smoothing mechanism 50 are mounted on one end of the feeding mechanism 30 for threading and flattening the ends of the individual steel bars; a storage mechanism 60 is provided next to the feeding mechanism 30 for temporarily storing steel bars that have been threaded and / or flattened; and a cage weaving mechanism 70 for weaving the steel bars into a steel cage using the steel bars that have been threaded and flattened.

[0049] The weaving cage mechanism 70 includes a weaving cage bracket 71, and an axial moving mechanism 72 for synchronously moving the steel bars is slidingly arranged along the length direction of the weaving cage bracket 71. A stirrup conveying mechanism 73 is installed above the position of the weaving cage bracket 71 near the end, and a clamping mechanism for temporarily fixing the steel bars is arranged on both sides. A weaving cage module 74 for fixing the intersections of the stirrups and the steel bars one by one is arranged at the corresponding position below.

[0050] The working principle of this embodiment and its differences from the prior art are described and explained below in conjunction with the accompanying drawings:

[0051] The weaving system provided in this embodiment uses bundles of steel bars delivered from the steel mill as processing raw materials, and obtains special-shaped steel cages through systematic processing. The existing steel cages are usually woven cylindrical steel cages, that is, the axial direction uses thicker diameter steel bars, generally threaded steel bars, which are installed on the tooling in a circular array, and then the smooth steel bars with smaller diameters are used as stirrups to wrap around the axial steel bars, and then tied into a cage. It is worth noting that the woven cage described in the present invention refers to the general term for the process of weaving and fixing discrete steel bars into a steel cage with a certain structural strength and shape. The fixing method can be binding, welding, or other existing methods or structures that can fix the relative positions between steel bars. The existing technology has the problem that the cage is slow to withdraw, and the tooling needs to be removed before the cage can be withdrawn; secondly, it can only be used for binding columnar steel cages, and is not suitable for special-shaped steel cages. For special-shaped steel cages, such as cross-shaped and T-shaped node piles used for the construction of grid-type continuous anti-seepage walls, all have corner node piles, and the existing cylindrical steel cages cannot meet the requirements. In response to this technical problem, this embodiment provides a woven cage module 74 that can move up, down, left, and right. See the structure. Figure 10-13 As shown, this structure is one of the key technical innovations of this embodiment. The overall processing process of the weaving cage of this embodiment is as follows:

[0052] See also Figure 1 The illustrated embodiment depicts a feeding mechanism 10 and a sawing mechanism 20. The feeding mechanism 10 is used to place, support, and transport bundles of rebar. The bundles are then fed to the sawing mechanism 20 for securing and sawing. The sawing serves two purposes: 1. to align the ends of uneven rebar cages; 2. to saw the finished rebar bundles to the same length as the cage braiding, facilitating subsequent processing and cage braiding. The sawing mechanism 20 in this embodiment is essentially identical to conventional sawing devices. It utilizes a high-speed rotating saw blade to saw the bundles of rebar, achieving the purpose of sawing and feeding. The unloading mechanism 30 serves as a temporary storage mechanism for finished rebar. It sequentially feeds the rebar to the feeding mechanism 80, which then feeds it to the threading mechanism 40 and the smoothing mechanism 50 at each end for threading and smoothing. The threaded and smoothed rebar is then flipped over by the feeding mechanism 80 and transferred to the storage mechanism 60 for temporary storage. After completing the above process, the processing of the steel bars is completed. The next step is the most important steel bar unit weaving, that is, using the processed steel bars to weave into steel bar units with a certain structural strength and shape. However, the steel bar unit is not a steel cage, but only provides standard components for the subsequent final steel cage, which is conducive to the rapid weaving and combination of the steel cage. Figure 10-13As shown, the axial reinforcement is placed along the cage support 71 and the end is fixedly connected to the axial movement mechanism 72. The connection method is clamping or threading, preferably threaded threading. After the arrangement and installation, the axial reinforcement arrangement is completed. The stirrups are transported one by one using the stirrup conveying mechanism 73. The stirrups are temporarily fixed using the clamping mechanism set on both sides of the cage support 71 to avoid displacement during the fixing process, such as welding or tying, which is not conducive to the precise execution of the cage. When fixing the cage, the cage module 74 that can move up and down and left and right is used to weld or tie the intersection of the axial reinforcement and the stirrups, finally forming a fixed structure steel unit.

[0053] Example 2:

[0054] In order to achieve efficient, accurate and rapid weaving and fixing of the steel cage, this embodiment further improves the cage module 74 on the basis of embodiment 1. Specifically, the cage module 74 includes a gantry fixedly mounted on the ground or the cage support 71, and the gantry includes vertical columns on both sides, and a lifting module 742 driven by a lifting driver 741 is slidably provided on the column, and the two lifting modules 742 are connected by a horizontal screw rod 743 and a horizontal guide rail 744 provided in parallel; and a welding module 746 or a threading module slidably provided on the horizontal screw rod 743 and the horizontal guide rail 744. The threading module can adopt the existing threading / tying mechanism to replace welding fixation, which belongs to the prior art, but the strength of the welding structure is usually better, so the following is explained by taking welding as an example: See Figure 12 As shown, the welding module 746 is capable of vertically moving up and down under the drive of the lifting drive 741. The welding module 746 includes a horizontal drive 745 that drives the welding module 746 back and forth along the horizontal screw 743. Driven by the horizontal drive 745, the welding module 746 moves along the horizontal screw 743. This allows the welding module 746 to move freely up, down, left, and right within the plane of the cross-section of the steel bar, enabling welding of the intersections of the axial steel bars and stirrups arranged at the top and sides, as well as a second welding head 748 for welding the horizontally arranged steel bars and a first welding head 747 for welding the vertically arranged steel bars. After welding a stirrup to an axially arranged main bar, the axial movement mechanism 72 drives the stirrup along the length of the main bar, moving a distance equal to the spacing between adjacent stirrups. The welding process is then repeated until all stirrups required for welding are completed. To facilitate the rapid placement of the axial main bars, the end of the weaving cage mechanism 70 is provided with multiple guide funnels 711 for guiding the steel bars. See also Figure 10 shown.

[0055] In order to meet the requirements of weaving and fixing the steel cage with different stirrup spacing, in this embodiment, the axial movement mechanism 72 includes a power box, and a set of driving gears and driven gears are respectively provided on both sides of the power box, as well as a threaded joint 723 for threading the steel bar head. The threaded joint 723 can be electric or a manually threaded structure, as long as it can meet the requirements of the detachable fixed connection of the main reinforcement; the two sides of the weaving cage bracket 71 are fixedly installed with a translation rack 721 that meshes with the driving gear 722 and the driven gear. When the current stirrup welding is completed, the driving gear 722 meshes with the translation rack 721 under the action of the driving force, driving the entire axial movement mechanism 72 to move along the length direction of the main reinforcement. The amount of movement is determined by a preset control unit and can be determined according to actual construction needs and the spacing and density of the steel cage stirrup design; the axial movement mechanism 72 is only an execution end and is not affected by the actual spacing.
