Description

Technical Field

[0001] This utility model relates to the field of diaphragm wall casting technology, and in particular to a diaphragm wall concrete casting support. Background Technology

[0002] The diaphragm wall is a foundational engineering project. On the ground, trenching machinery is used to excavate a narrow, deep trench along the perimeter axis of the deep excavation project, under the condition of grout wall protection. After cleaning the trench, a steel cage is suspended in the trench, and then underwater concrete is poured using the tremie method to form a unit trench segment. This process is carried out segment by segment to build a continuous reinforced concrete wall underground, which serves as a water interception, seepage prevention, load-bearing, and water-retaining structure.

[0003] When the existing equipment is pouring concrete, the hopper machine is prone to shaking, which causes uneven concrete drop. This can easily lead to unevenness and segregation of the diaphragm wall pouring surface, affecting the wall's density and strength, reducing its impermeability and load-bearing capacity, and creating potential structural safety hazards. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] The diaphragm wall concrete pouring support disclosed in this utility model is mainly used in scenarios where, during the pouring of existing equipment, the hopper machine is prone to shaking, causing uneven concrete drop, resulting in an uneven diaphragm wall pouring surface, affecting the wall performance, and creating potential safety hazards.

[0032] Reference Figures 1-5 The diaphragm wall concrete pouring support includes:

[0033] Workbench 1, with multiple support legs 2 fixedly connected to the bottom end of workbench 1;

[0034] The hopper 3 is located above the workbench 1, and the workbench 1 has a round hole located directly below the hopper 3.

[0035] The gantry frame 4 is fixedly connected to the top of the workbench 1, and the hopper machine 3 is located inside the gantry frame 4;

[0036] Two hopper stabilizing components 11 are located on both sides of the hopper machine 3. The hopper stabilizing components 11 are used to provide stable support for the hopper machine 3 during concrete pouring.

[0037] Two ground adsorption and stabilization components 7 are symmetrically arranged on opposite sides of the outrigger 2. The ground adsorption and stabilization components 7 are used to stabilize the ground on both sides during concrete pouring to prevent displacement.

[0038] Reference Figure 1 , Figure 2 and Figure 3 In a preferred embodiment, the hopper stabilizing assembly 11 includes:

[0039] Stabilizing plate 1108, which is attached to one side of the hopper machine 3;

[0040] The push plate 1105 is located on the side of the stabilizing plate 1108 away from the hopper machine 3;

[0041] The connector 1101 is located on the side of the push plate 1105 away from the stabilizing plate 1108, and the bottom end of the connector 1101 is fixedly connected to the top of the workbench 1.

[0042] In this design, a connecting frame 1107 is fixedly connected to the side of the stabilizing plate 1108 away from the hopper machine 3. A connecting rod 1106 is fixedly connected inside the connecting frame 1107. The outer side of the connecting rod 1106 is movably connected to the inner side of the top of the push plate 1105. The telescopic end of the electric telescopic rod 1104 is fixedly connected to the side of the push plate 1105 away from the stabilizing plate 1108.

Two spring rods 1103 are fixedly connected to the side of the connector 1101 near the electric telescopic rod 1104. The ends of the spring rods 1103 away from the connector 1101 are all fixedly connected to the side of the push plate 1105 near the electric telescopic rod 1104.

[0043] The stabilizing plate 1108 in the hopper stabilizing component 11 is attached to the hopper machine 3, providing reliable lateral support to offset the impact of concrete and the shaking of the hopper itself during pouring, so that the hopper machine 3 is always accurately aligned with the pouring port, ensuring that the concrete falls continuously and stably, avoiding missed pouring or uneven pouring, and ensuring the integrity of the diaphragm wall pouring.

[0044] Reference Figures 1-4 In a preferred embodiment, the ground adsorption and retention component 7 includes:

[0045] The fixing plate 701 is fixedly connected to the opposite side of the outrigger 2;

[0046] The movable plate 706 is located below the fixed plate 701;

[0047] Multiple suction cups 708 are fixedly connected to the bottom of the movable plate 706, and the suction cups 708 are used to adhere to the ground.

[0048] In this design, a connecting frame 703 is fixedly connected to the top of the fixed plate 701, and a telescopic drive rod 704 is fixedly connected inside the connecting frame 703. A through hole is provided on the fixed plate 701, and the outer side of the telescopic drive rod 704 is movably connected to the inside of the through hole. The telescopic end of the telescopic drive rod 704 is fixedly connected to the top of the movable plate 706. Two moving rods 702 are fixedly connected to the top of the movable plate 706. Two slots are provided on the fixed plate 701, and the moving rods 702 are movably connected inside the slots. A vacuum pump 705 is fixedly connected to the top of the fixed plate 701, and a vacuum tube 707 is fixedly connected to the vacuum end of the vacuum pump 705. The bottom end of the vacuum tube 707 is fixedly connected to the top of the suction cup 708, and the outer side of the vacuum tube 707 is fixedly connected to the inner side of the movable plate 706.

[0049] The ground adsorption and fixation component 7 uses a vacuum pump 705 to create a vacuum adsorption between the suction cup 708 and the ground, generating a strong adsorption force to firmly fix the equipment. This effectively counteracts external forces such as the impact of the hopper machine 3 and equipment vibration during concrete pouring, preventing displacement and shaking of the work platform, ensuring stability during the pouring process, and allowing for precise and continuous concrete placement.

[0050] Reference Figures 1-3In a preferred embodiment, a placement frame 8 is fixedly connected to the top of the workbench 1, a motor frame 10 is fixedly connected to the top of the workbench 1, a drive motor 6 is fixedly connected inside the motor frame 10, the power output shaft of the drive motor 6 is connected to a rotating rod 9 via a coupling, the outer sides of the rotating rod 9 are movably connected to both ends inside the placement frame 8, and a wire rope 5 is movably connected to the outer sides of the rotating rod 9. Two connecting plates 14 are fixedly connected to the top inner side of the gantry frame 4, a fixing rod 16 is fixedly connected to the opposite side of the connecting plates 14, a rotating shaft 15 is movably connected to the outer side of the fixing rod 16, the wire rope 5 passes through the outer side of the rotating shaft 15, a ring buckle frame 13 is fixedly connected to the bottom end of the wire rope 5, a hanging rope 12 is fixedly connected to the bottom end of the ring buckle frame 13, and the bottom ends of the hanging ropes 12 are all fixedly connected to the top of the hopper machine 3.

[0051] Working principle: The workbench 1 is supported by the support legs 2 and is positioned at a preset position directly above the pouring opening, providing an operating plane for subsequent operations. The drive motor 6 drives the rotating rod 9 to rotate. When the rotating rod 9 rotates, the outer steel wire rope 5 is retracted and extended. The rotating shaft 15 on the fixed rod 16 fixed by the connecting plate 14 on the inner side of the top of the gantry frame 4 assists in guiding the steel wire rope 5, changing the direction of the force, so that the steel wire rope 5 is lowered smoothly. As the steel wire rope 5 is lowered, the hopper 3 slowly descends, and finally the hopper 3 is precisely positioned directly above the round hole of the workbench 1, in preparation for pouring.

[0052] When the electric telescopic rod 1104 starts to extend, it pushes the push plate 1105 to move towards the hopper 3. Under the continuous extension of the electric telescopic rod 1104, the push plate 1105 moves closer to the hopper 3. The connecting rod 1106 can rotate to the inner side of the top of the push plate 1105 to adapt to the angle, so that the stabilizing plate 1108 close to the outer side of the hopper 3 can accurately fit the surface of the hopper 3. The electric telescopic rod 1104 maintains extension, and the spring rod 1103 provides elastic support to stabilize the hopper and prevent shaking during pouring.

[0053] The telescopic drive rod 704 extends, pushing the movable plate 706 downward along the guide rod 702. The movable rod 702 slides in the slot of the fixed plate 701 to ensure directional stability, so that the suction cup 708 is in contact with the ground. Then the vacuum pump 705 starts, and the air between the suction cup 708 and the ground is drawn out through the vacuum tube 707 to form a vacuum. Atmospheric pressure is used to make the suction cup 708 firmly adhere to the ground. The telescopic drive rod 704 cooperates to maintain the fixed position and prevent the equipment from shifting.

[0054] After the hopper machine (3) is hoisted, positioned, and stabilized, and after the ground is adsorbed and fixed, the bottom unloading structure of the hopper machine 3 is opened. The concrete is subjected to gravity and falls into the pouring port below through the round hole of the workbench 1. During the pouring process, the hopper stabilizing component 11 continuously provides lateral support to offset the impact force of the falling concrete. The ground adsorption and fixing component 7 ensures the overall stability of the equipment, so that the concrete is poured evenly and continuously until the pouring operation of this section of the diaphragm wall is completed.

[0055] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of 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 protection scope of this utility model.
