Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete pouring technology for shaft guide walls, and in particular to a rapid layered concrete pouring device for shaft guide walls. Background Technology
[0002] Before constructing the trench for the diaphragm wall, a guide wall must be built. The guide wall is crucial to ensuring the accurate positioning of the diaphragm wall and the quality of the trench. During construction, the guide wall is frequently subjected to static and dynamic loads from the reinforcing cage, the tremie pipes used for pouring concrete, and the drilling rig. Therefore, careful design and construction are essential before the formal construction of the diaphragm wall can proceed. Due to the limited space at the site of the vertical shaft in urban water conservancy projects, ultra-deep guide walls under adverse geological conditions require layered vertical excavation and pouring, which presents the problem of misaligned layers and the inability to pour the upper and lower layers densely.
[0003] Therefore, a rapid layered concrete pouring device for shaft guide walls is needed to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a rapid layered concrete pouring device for vertical shaft guide walls to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A rapid concrete layering pouring device for a vertical shaft guide wall includes: several PVC conduits, iron wire, and wooden plugs. The wooden plugs are detachably connected to both ends of the PVC conduits. One end of the iron wire is fixedly connected to the PVC conduit, and the other end of the iron wire is fixedly connected to the guide wall reinforcement. The bottom of the PVC conduit extends out of the layering point of the guide wall, and the PVC conduit is located in the center of the guide wall.
[0007] Preferably, the connection end between the wooden plug and the PVC conduit is tapered.
[0008] Preferably, the plurality of PVC conduits are evenly arranged along the guide wall.
[0009] Preferably, the outer wall of the PVC conduit is provided with a marking line.
[0010] Preferably, the diameter of the PVC conduit is not less than 160 mm.
[0011] This utility model discloses a rapid layered concrete pouring device for vertical shaft guide walls, which has the following beneficial effects.
[0012] This invention utilizes a PVC conduit with a diameter of not less than 160mm installed during the pouring of the first layer of the guide wall. This conduit serves as a channel for pouring the second layer of concrete, shifting the pouring of the lower guide wall concrete from side pouring to top pouring. This ensures the density of the upper and lower layers of concrete in the guide wall and prevents misalignment between the upper and lower layers. The wooden plug of the device can be reused repeatedly. This device is simple to construct, easy to operate, and uses economical materials. It ensures construction safety and quality through a simple device. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0018] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Example 1
[0019] Reference Figures 1 to 2A rapid layered concrete pouring device for a vertical shaft guide wall includes: several PVC conduits 2, iron wires 3, and wooden plugs 1. The wooden plugs 1 are detachably connected to both ends of the PVC conduits 2. One end of the iron wire 3 is fixedly connected to the PVC conduit 2, and the other end is fixedly connected to the guide wall reinforcement 4. The bottom of the PVC conduits 2 extends through the layering point 5 of the guide wall and is positioned in the center of the guide wall 6. In this embodiment, the wooden plugs 1 can be reused repeatedly, and can also be temporarily replaced with tape on site, greatly improving on-site construction efficiency. By installing PVC conduits 2 with a diameter of not less than 160mm during the pouring of the first layer of the guide wall 6, serving as a channel for pouring the second layer of concrete, the pouring of the lower layer of the guide wall 6 is adjusted from side pouring to top pouring, ensuring the compactness of the upper and lower layers of concrete in the guide wall 6 and preventing misalignment between the upper and lower layers of the guide wall 6. When using the rapid concrete layering pouring device for the vertical shaft guide wall 6, after excavating the guide wall 6 to a certain depth and designated elevation (i.e., at the layering point 5), a PVC conduit 2 with a diameter of not less than 160mm is installed centered between the guide walls 6, evenly distributed along both sides of the guide walls 6. The PVC conduits 2 are fixed to the guide wall reinforcement 4 with iron wire 3 at designated intervals. After binding, wooden plugs 1 are used to seal both ends of the PVC conduits 2. Anti-clogging measures for PVC conduits 2: Before placing the PVC conduits 2, inspect them to ensure the pipe wall is smooth, without damage or holes. Wooden plugs 1 are used to seal both ends of the PVC conduits 2 to prevent the first layer of concrete from entering and blocking them, thus rendering the PVC conduits 2 unusable.
[0020] Preferably, in this embodiment, the connection end between the wooden plug 1 and the PVC conduit 2 is tapered.
[0021] Preferably, in this embodiment, several PVC conduits 2 are evenly arranged along the guide wall 6.
[0022] Preferably, in this embodiment, the diameter of the PVC conduit 2 is not less than 160 mm. Example 2
[0023] Please refer to Figure 3 Based on Embodiment 1, in this embodiment, as a preferred embodiment, a marking line is provided on the outer wall of the PVC conduit 2. In order to prevent the PVC conduit 2 from shifting during pouring, one PVC conduit 2 is connected to the guide wall reinforcement 4 by multiple iron wires 3. In order to make the spacing between the iron wires 3 uniform, the marking line is used to indicate the connection spacing of the iron wires 3, which facilitates construction. The marking line can be uniformly marked with ink lines when the PVC conduit 2 is cut.
[0024] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Substitutions may include replacements for some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the scope of protection of this utility model.
