Abstract
Description
Technical Field
[0001] This application relates to the field of water conservancy engineering technology, and in particular to a steel cage device for a continuous underground wall of an ultra-deep vertical shaft. Background Technology
[0002] With the rapid development of urban construction, underground engineering projects in various regions are also trending towards larger and deeper structures. In order to ensure construction safety, deeper underground continuous walls are needed as support structures.
[0003] Traditional diaphragm walls utilize interlocking pipes or steel joints, which suffer from slow construction efficiency and high risk of joint leakage. With advancements in machinery manufacturing processes, the emergence of twin-wheel trenching machines has offered a new solution to these problems. Based on this equipment, a milling joint process has been developed. This process relies on the interlocking of concrete to form dense diaphragm wall joints, offering significant advantages such as excellent joint waterproofing, stable trenching, high verticality, and minimal construction impact. These advantages have led to the widespread application of this technology in ultra-deep diaphragm wall projects.
[0004] However, when using the milling joint construction process for diaphragm walls, the lowering of the reinforcement cage in the first-order trench can easily encroach on the joint position. This can cause the double-wheel milling machine in the adjacent second-order trench to easily hit the reinforcement cage of the already cast-in-place trench section, resulting in equipment damage, construction delays, increased costs, and serious impact on trenching efficiency. Furthermore, it can affect the overall structural strength of the diaphragm wall and make it impossible to guarantee the quality of construction. Utility Model Content
[0005] To address or partially address the problems existing in related technologies, this application provides a steel cage device for ultra-deep vertical shaft underground continuous walls, which can ensure the overall structural strength of the steel cage wall after construction, effectively guarantee the quality of construction, and improve trenching efficiency.
[0006] This application provides a steel cage device for an ultra-deep vertical shaft underground continuous wall, including a steel cage body, and lowering limit devices are installed at intervals on the left and right sides of the steel cage.
[0007] The lowering limiting device includes: a limiting tube, a fixing plate, and a limiting plate;
[0008] The limiting tube is a cylindrical tube with a cross section, and the diameter of the limiting tube is the same as the width of the milling joint.
[0009] The fixing plate has bent right-angle clamps at both ends, and two fixing through holes are provided on the fixing plate. One end of the fixing plate passes through the limiting tube.
[0010] The limiting plate is provided with a limiting through hole and a limiting slot. The limiting plate is installed on both sides of the limiting tube through the limiting slot, and is connected and fixed to the fixing plate by bolts passing through the limiting through hole and the fixing through hole in sequence, so that the limiting tube is fixedly installed on the fixing plate.
[0011] Optionally, in some embodiments of this application:
[0012] The right-angle clip of the fixing plate is provided with a first pull ring hole;
[0013] The limiting plate has second pull ring holes at both ends.
[0014] Optionally, in some embodiments of this application:
[0015] The lowering limit device also includes: a pull rope;
[0016] The pull rope is installed in each of the first pull ring holes and the second pull ring holes.
[0017] Optionally, in some embodiments of this application:
[0018] The limiting tube is made of plastic.
[0019] The fixing plate and the limiting plate are made of steel.
[0020] Optionally, in some embodiments of this application:
[0021] The installation spacing of the upper limit devices on the left and right sides of the steel cage is 400mm.
[0022] The technical solution provided in this application may include the following beneficial effects:
[0023] This application utilizes limiting plates to fix the limiting tubes on the plates. By securing the limiting plates to both sides of the reinforcing cage, the limiting tubes can be vertically fixed to both sides of the cage. This vertical fixation of the limiting tubes on both sides of the reinforcing cage limits its movement during installation, ensuring the verticality of the cage's descent and meeting the width requirements of the milling joints. Furthermore, during the pouring of the adjacent trench, the concrete automatically fills the limiting tubes. When milling adjacent trenches, only the limiting tubes are milled away, without affecting the overall structural strength of the reinforcing cage wall after pouring. This effectively ensures construction quality and improves trenching efficiency.

[0038] When using milling joint construction technology for diaphragm walls, the lowering of the I-sequence trench reinforcement cage 1 can easily encroach on the joint position. This can cause the double-wheel milling machine in the adjacent II-sequence trench to easily hit the already cast-in-place section of reinforcement cage 1, resulting in equipment damage, construction delays, increased costs, and serious impact on trenching efficiency. Furthermore, it can affect the overall structural strength of the diaphragm wall and make it impossible to guarantee the quality of construction.
[0039] To address the aforementioned issues, this application provides a steel cage 1 device for ultra-deep vertical shaft underground continuous wall, which can ensure the overall structural strength of the steel cage 1 wall after construction, effectively guarantee the construction quality, and improve trenching efficiency.

[0048] See Figure 1-7 A steel cage 1 device for an ultra-deep vertical shaft underground continuous wall includes a steel cage 1 body, and a lowering limit device 2 is installed at intervals on the left and right sides of the steel cage 1.
[0049] The lowering limiting device 2 includes: a limiting tube 3, a fixing plate 4, and a limiting plate 5.
[0050] The limiting tube 3 is a cylinder with a cross section 301, and the diameter of the limiting tube 3 is the same as the width of the milling joint.
[0051] The fixing plate 4 has two bent right-angle clamping plates 401 at both ends, and two fixing through holes 402 on the fixing plate 4. One end of the fixing plate 4 passes through the limiting tube 3.
[0052] The limiting plate 5 is provided with a limiting through hole 501 and a limiting slot 502. The limiting plate 5 is installed on both sides of the limiting tube 3 through the limiting slot 502, and is connected and fixed to the fixing plate 4 by bolts passing through the limiting through hole 501 and the fixing through hole 402 in sequence, so that the limiting tube 3 is fixedly installed on the fixing plate 4.
[0053] In this embodiment, by using the limiting plate 5, the limiting tube 3 can be fixedly installed on the limiting plate 5. By clamping and fixing the limiting plate 5 on both sides of the reinforcing cage 1, the limiting tube 3 can be vertically fixed on both sides of the reinforcing cage 1. By vertically fixing the limiting tube 3 on both sides of the reinforcing cage 1, the reinforcing cage 1 can be limited during installation, ensuring the verticality of the lowering of the reinforcing cage 1 and meeting the width requirements of the milling joint. At the same time, during the pouring of the sequential trench, the concrete will automatically fill the limiting tube 3. When milling the adjacent sequential trench, only the limiting tube 3 will be milled off, without affecting the overall structural strength of the reinforcing cage 1 wall after pouring. This effectively ensures the quality of construction and improves the trenching efficiency.
[0054] Specifically: the limiting tube 3 is made of plastic, specifically HDPE pipe; the fixing plate 4 and the limiting plate 5 are made of steel.
[0055] In this embodiment, HDPE pipe is used. It is lightweight, has high strength, and a certain degree of toughness. The circular surface of the limiting pipe 3 has a small contact area with the groove wall, making it less likely to get stuck during lowering. The installation is simple and fast.
[0056] Specifically: the right-angle clamping plate 401 of the fixing plate 4 is provided with a first pull ring hole 4011; the two ends of the limiting plate 5 are provided with second pull ring holes 503.
[0057] Specifically, the lowering limit device 2 also includes a pull rope.
[0058] The pull rope is a steel rope (not shown in the attached diagram), and the pull rope is installed in each of the first pull ring holes 4011 and the second pull ring holes 503.
[0059] In this embodiment, after the limiting plate 5 is clipped onto both sides of the reinforcing cage 1, it can be fixed to the reinforcing bars of the reinforcing cage 1 by pulling ropes, facilitating quick installation by construction personnel and improving construction efficiency. Specifically, to ensure the installation stability of the limiting plate 5, after fixing the limiting plate 5 to the reinforcing bars of the reinforcing cage 1 by pulling ropes, the limiting plate 5 is further fixed by welding.
[0060] Specifically, the installation spacing of the upper limit devices on the left and right sides of the steel cage 1 is 400mm.
[0061] In this embodiment, by setting an appropriate installation spacing, the time wasted due to adjusting the position of the limiting device can be reduced, effectively improving construction efficiency.
[0062] The technical solutions in this application have the following beneficial effects:
[0063] This application utilizes a limiting plate 5 to fix the limiting tube 3 onto the limiting plate 5. By clamping and fixing the limiting plate 5 to both sides of the reinforcing cage 1, the limiting tube 3 can be vertically fixed to both sides of the reinforcing cage 1. By vertically fixing the limiting tube 3 to both sides of the reinforcing cage 1, the reinforcing cage 1 can be limited during installation, ensuring its verticality and meeting the width requirements of the milling joint. Simultaneously, during the pouring of the sequential trench, the concrete automatically fills the limiting tube 3. When milling adjacent sequential trenches, only the limiting tube 3 is milled away, without affecting the overall structural strength of the reinforcing cage 1 wall after pouring. This effectively ensures construction quality and improves trenching efficiency.
