[0025] As shown in Figure 1 and Figure 2 In an embodiment of the utility model, a corner reinforced concrete cage includes a first frame 1 and a second frame 2 perpendicular to each other, a shaping limiting piece 3 is arranged in the first frame 1 and the second frame 2, one end of the shaping limiting piece 3 is connected with the first frame 1, the other end of the shaping limiting piece 3 is connected with the second frame 2, a limiting part 301 is arranged on the shaping limiting piece 3, and the limiting part 301 is used for limiting a pouring guide pipe 4.

[0026] When the reinforcement cage is made: according to the design size, a first frame 1 and a second frame 2 perpendicular to each other are made respectively, and it is ensured that the specifications meet the construction requirements of the corner width of the underground continuous wall. After the production is completed, the shaping and limiting part 3 is installed in the first frame 1 and the second frame 2. When installing, one end of the shaping and limiting part 3 needs to be firmly connected with the first frame 1, and the other end is also stably connected to the second frame 2, generally by welding connection, the single-sided welding length is greater than 10 times the diameter of the reinforcement, the double-sided welding length is greater than 5 times the diameter of the reinforcement, to ensure the reliability of the connection, so that it can effectively play a shaping role. Because the shaping and limiting part 3 is provided with a limiting part 301, the position and size of the limiting part 301 need to be designed according to the actual specifications and installation requirements of the pouring guide pipe 4, to ensure that the subsequent pouring guide pipe 4 can be accurately limited.

[0027] In the embodiment, by setting the shaping and limiting part 3, on the one hand, the shaping and limiting part 3 connects the first frame 1 and the second frame 2, enhances the overall structural strength of the reinforcement cage, changes the situation that the two sides of the corner width reinforcement cage are easy to deform when hoisting, effectively reduces the construction difficulty, and ensures that the reinforcement cage can be accurately placed into the corresponding slot section, improves the construction quality and progress of the underground continuous wall. On the other hand, the limiting part 301 on the shaping and limiting part 3 can stably position the pouring guide pipe 4, solve the problem of the setting of the inclined reinforcement affected by the auxiliary instrument in the past, make the pouring guide pipe 4 more reasonable, and further ensure the smooth progress of the concrete pouring and other links in the construction process, improve the efficiency and quality of the entire underground space construction.

[0028] As shown in Figure 1 In a preferred example, the limiting part 301 is annular, the inner ring of the limiting part 301 is the same as the cross-sectional shape of the pouring guide pipe 4, and a plurality of pairs of connecting rods 302 are arranged on the outer side of the limiting part 301. Each pair of connecting rods 302 is coaxially arranged, one end of the connecting rod 302 is connected with the limiting part 301, and the other end of the connecting rod 302 is connected with the first frame 1 or the second frame 2.

[0029] A reinforcing rib 303 is arranged between the connecting rod 302 and the limiting part 301.

[0030] In the embodiment, the limiting part 301 is annular and the inner ring is the same as the cross-sectional shape of the pouring guide pipe 4, which can realize accurate limiting of the pouring guide pipe 4, reduce the displacement or shaking of the pouring guide pipe 4 in the construction process, thereby ensuring that the concrete pouring operation can be stably and uniformly carried out, improving the quality of the concrete pouring, and avoiding problems such as pouring not dense caused by deviation of the guide pipe position.

[0031] Secondly, a plurality of pairs of coaxial connecting rods 302 are arranged outside the limiting part 301, and the connecting rods 302 are respectively connected with the limiting part 301 and the first frame 1 or the second frame 2, further enhancing the stability of the entire structure. Through these connecting rods 302, the limiting part 301 and the frame part of the reinforcement cage form a stable whole, which not only better limits the pouring guide pipe 4, but also enables the external force borne by the pouring guide pipe 4 during work to be evenly dispersed to the frame of the reinforcement cage, avoiding the case of excessive local stress.

[0032] Furthermore, the reinforcing ribs 303 arranged between the connecting rods 302 and the limiting part 301 further strengthen the strength of the connecting part. The reinforcing ribs 303 can effectively resist external forces such as vibration and pressure generated during the operation of the pouring guide pipe 4, prevent the connecting point between the limiting part 301 and the connecting rod 302 from loosening or being damaged, thereby prolonging the service life of the entire reinforcement cage and related auxiliary structures, and ensuring the continuous stability of the construction process.

[0033] As shown in the drawings, Figure 2 In a preferred example, a plurality of shaped limiting parts 3 are arranged in the vertical direction, and connecting pieces 304 are arranged between adjacent shaped limiting parts 3. The connecting pieces 304 can be annularly arranged connecting ribs, or helically arranged connecting ribs.

[0034] In this embodiment, from the aspect of improving structural strength, the plurality of shaped limiting parts 3 and the connecting pieces 304 jointly construct a stable support system. The annular connecting ribs are arranged around adjacent shaped limiting parts 3, like a "reinforcing ring" closely connected one by one, evenly dispersing and transmitting stress in various directions, enhancing the stability of the entire corner reinforcement cage in the vertical direction and the overall structure. The helical shape of the helically arranged connecting ribs forms an installation track, facilitating the placement of the pouring guide pipe 4.

[0035] In terms of positioning of the pouring guide pipe 4, the limiting parts 301 on the plurality of shaped limiting parts 3 originally play a role of multi-point positioning for the pouring guide pipe 4. The connecting pieces 304 laterally constrain the pouring guide pipe 4, ensuring that the pouring guide pipe 4 always remains in the ideal vertical position, preventing it from deviating in the horizontal direction during pouring, ensuring that the concrete pouring can be carried out along the predetermined path, improving the quality and uniformity of the concrete pouring, and providing a solid guarantee for the construction quality of the underground continuous wall.

[0036] As shown in the drawings, Figure 2 In a preferred example, the first frame 1 and the second frame 2 are respectively provided with scissors 102 in the vertical plane.

[0037] The scissors brace 102 is arranged in a cross shape in the vertical plane of the frame, which can effectively change the force transmission path. When the reinforcement cage is subjected to external forces such as tension during hoisting, extrusion during placement into the slot section, and the like, the scissors brace 102 can disperse these external forces to the entire frame system. Through its own triangular stable structure characteristics, the deformation resistance of the frame in the vertical plane is enhanced, effectively preventing local sagging, twisting or bending of the frame, and improving the overall stability and load-bearing capacity of the reinforcement cage.

[0038] As shown in the drawings, Figure 1 In one preferred example, the first frame 1 and / or the second frame 2 are provided with chamfers 101 at the vertical edges of the empty ends.

[0039] In this embodiment, the chamfer 101 enables the reinforcement cage to be placed more smoothly when inserted into the joint box, reducing the risk of jamming and collision due to the straight edges, reducing the construction difficulty and operation time, and improving the construction efficiency.

[0040] As shown in the drawings, Figure 1 and Figure 2 In one preferred example, the first frame 1 and the second frame 2 are provided with a protective layer positioning member 5 on the outer side, and the protective layer positioning member 5 includes a pivot shaft 501 connected to the first frame 1 or the second frame 2, and a positioning disc 502 rotatably sleeved on the pivot shaft 501.

[0041] During hoisting of the reinforcement cage, the positioning disc 502 can roll, on the one hand, to maintain the spacing between the reinforcement cage and the slot wall, effectively avoiding jamming caused by scratching and collision between the reinforcement cage and the slot wall during hoisting; on the other hand, rolling reduces the frictional resistance between the two, making the placement process more smooth and efficient, reducing the construction difficulty and improving the construction efficiency.

[0042] During the concrete pouring stage, the positioning disc 502 continues to play a positioning role, continuously and stably maintaining the spacing between the reinforcement cage and the slot wall, ensuring that the reinforcement cage is always in the middle area of the slot section, ensuring that the concrete can uniformly wrap the reinforcement cage during pouring, avoiding problems such as uneven concrete pouring and inconsistent protective layer thickness caused by the offset of the reinforcement cage, improving the pouring quality, and ensuring the structural stability and durability of the underground continuous wall.

[0043] As shown in the drawings, Figure 2 In one preferred example, the first frame 1 and the second frame 2 are provided with first lifting lugs 103 at the top and second lifting lugs 104 at the middle.

[0044] In the embodiment, the first lifting lug 103 provides a stable force point for the main hoist, and the second lifting lug 104 provides a stable force point for the auxiliary hoist. In the initial stage of hoisting, the main hoist and the auxiliary hoist cooperate to smoothly lift the reinforcement cage from the ground, ensuring the stability of the initial stage of the entire hoisting process. During the hoisting process, the auxiliary hoist cooperates with the main hoist to adjust the posture and angle of the reinforcement cage, ensuring that the reinforcement cage is in a vertical state, and then the auxiliary hoist is loosened, and the main hoist hoists the reinforcement cage into the corresponding slot section.

[0045] As shown in Figure 2 In a preferred example, the top and / or bottom of the first frame 1 and the second frame 2 are provided with threaded joints 105.

[0046] Each threaded joint 105 is divided into groups, and each group of threaded joints 105 is arranged at different heights.

[0047] For a deep diaphragm wall project, due to the corresponding deep enclosure structure, if the reinforcement cage is made and hoisted as a whole, the operation difficulty and risk will increase dramatically due to the excessive weight. By segmenting the reinforcement cage and using threaded sleeves to connect the threaded joints 105 of adjacent reinforcement cages, this problem is effectively solved. The arrangement of the threaded joints 105 provides a reliable and convenient way for the connection of the reinforcement cage, and the stable threaded connection can ensure that each segment of the reinforcement cage forms a tight and solid whole after splicing, thereby ensuring the mechanical properties of the entire enclosure structure. The segmented and staggered arrangement of the threaded joints 105 avoids the concentration of the joints at the same height, making the stress distribution at the connection of the reinforcement cage more uniform, thereby improving the stability and carrying capacity of the reinforcement cage as a whole. In the construction process, this design not only reduces the construction difficulty and improves the construction efficiency, but also ensures the construction quality and safety of the deep diaphragm wall enclosure structure.

[0048] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application.
