Description

Technical Field

[0001] The utility model belongs to the technical field of building construction equipment, and particularly relates to a gradient grouting device. Background Art

[0002] Gradient grouting is a specialized foundation treatment technique used to reinforce soil, increase foundation bearing capacity, or reduce soil permeability. The core of this technique is to control the grouting pressure and flow rate so that the grouting material gradually penetrates the soil according to predetermined design requirements, forming a reinforced area with a specific structural strength.

[0003] The patent document with the announcement number "CN220014581U" records "a wall structure gap grouting equipment, including frame one, frame two and frame three pivotally connected in sequence, and joint bearings are installed at the connections between frame one and frame two, frame two and frame three, and grouting pipes are installed in a cross-shaped manner on the outer sides of frame one, frame two and frame three. The end of the grouting pipe corresponding to frame one is connected to a feeding pipe, and the end of the grouting pipe corresponding to frame three is connected to a discharge pipe; frame one is rotatably installed with cylinder one near the lower side of frame two, and the output end of cylinder one is hinged to frame two, and frame two is rotatably installed with cylinder two at one end near frame three, and the output end of cylinder two is hinged to frame three. This equipment is reasonably designed and can realize grouting at different gradients, as well as grouting at different angles and ranges, which is beneficial to the injection of concrete slurry into wall gaps during construction, and is simple to operate and easy to use."

[0004] Due to the complexity and changeability of underground conditions, sometimes unexpected problems may be encountered even after detailed investigations. Artificial grouting will cause the foundation to be uneven in height, which requires personnel to level the concrete and easily causes gaps to appear inside the concrete. In rainy weather and changes in groundwater levels, operations will become more difficult. Utility Model Content

[0032] A gradient grouting device, comprising:

[0033] ladder frame 2;

[0034] Four hydraulic rods 1, the four hydraulic rods 1 are respectively fixedly connected to the lower ends of the four legs of the ladder frame 2;

[0035] The screw rod 8 and the two limiting rods 7 are fixedly connected to the inner walls of both sides of the trapezoidal frame 2 at their adjacent ends;

[0036] Funnel 4, funnel 4 is located on the upper side of the trapezoidal frame 2;

[0037] Two sliders 10, both of which are fixedly connected to the lower end of the funnel 4, and the two sliders 10 are slidably connected to the circumferential surfaces of the two limiting rods 7;

[0038] The threaded slider 11 is fixedly connected to the lower end of the funnel 4 and is threadedly connected to the circumferential surface of the screw rod 8;

[0039] Motor 5, the motor 5 is fixedly connected to one side end of the ladder frame 2, and one end of the screw rod 8 is fixed to the output shaft of the motor 5;

[0040] The pouring hopper 12 is fixed to the funnel 4 .

[0041] In a specific embodiment of the present invention, the trapezoidal frame 2 is made of steel material to ensure sufficient strength and stability. There are four hydraulic rods 1, which are fixed at the four corners of the bottom of the trapezoidal frame 2. By controlling the telescopic length of each hydraulic rod, the height of the entire device can be adjusted to meet the needs under specific working conditions. The screw rod 8 and the limit rod 7 provide a guiding function and also ensure stability during movement. The funnel 4 is used as a temporary storage container for grouting materials. There are two sliders 10 and a threaded slider 11 at the bottom. Among them, the two sliders 10 slide freely along the limit rod 7 for limiting and correction use, and the threaded slider 11 forms a threaded matching relationship with the screw rod 8 to achieve movement. The output shaft of the motor 5 is directly connected to the screw rod 8. When the motor 5 is started, the screw rod 8 can be driven to rotate to drive the funnel 4 to be accurately positioned in the horizontal direction. The pouring hopper 12 is mainly used to evenly introduce the material from the funnel 4 into the target area, and the concrete drops evenly from high to low. When pouring the foundation, it avoids the situation where there are gaps inside the concrete. Moreover, the device can work normally even on rainy days without unevenness, ensuring the stability of each layer of the foundation. It needs to be explained that the specific type of motor 5 and hydraulic rod 1 to be used is selected by relevant technicians familiar with this field, and the above-mentioned motor 5 and hydraulic rod 1 are all existing technologies, which will not be elaborated in this solution.

[0042] For details, please refer to Figure 1-Figure 3 Both side ends of the funnel 4 are fixedly connected with a slide plate 9, and the slide plate 9 is fitted with the upper end of the trapezoidal frame 2.

[0043] In this embodiment, the slide plate 9 increases the overall stability and carrying capacity of the device, and no shaking occurs when the funnel 4 moves.

[0044] For details, please refer to Figure 1-Figure 3 The lower end of the hydraulic rod 1 is fixedly connected to a universal wheel 3.

[0045] In this embodiment, the universal wheels 3 are convenient for people to push and can improve the mobility when the equipment needs to turn.

[0046] For details, please refer to Figure 1-Figure 3 Both side ends of the trapezoidal frame 2 are fixedly connected with guard plates 13, which are made of rubber and are flush with the legs of the trapezoidal frame 2.

[0047] In this embodiment: when the equipment is pouring concrete, the guard plate 13 can increase the stability of the device. Since the guard plate 13 is made of rubber, it will not shake when it comes into contact with an object, thereby enhancing stability.

[0048] For details, please refer to Figure 1-Figure 3 The lower inner wall of the funnel 4 is designed to be arc-shaped, and the inner walls on both sides of the funnel 4 are fixedly connected with an arc-shaped center plate 6.

[0049] In this embodiment, the arc-shaped lower inner wall of the funnel 4 can enhance the centering effect of the concrete. At the same time, under the centering effect of the arc-shaped centering plate 6, the concrete can be directly poured out through the pouring hopper 12.

[0050] For details, please refer to Figure 1-Figure 3 The arc-shaped center plate 6 is made of stainless steel.

[0051] In this embodiment, the arc-shaped center plate 6 is made of stainless steel, which is convenient for cleaning and can enhance its strength.

[0052] The working principle and usage process of the utility model are as follows: the overall height of the trapezoidal frame 2 is adjusted by controlling the telescopic length of the four hydraulic rods 1, and the motor 5 is turned on to make the screw rod 8 start to rotate. As the screw rod 8 rotates, the threaded slider 11 moves along the screw rod 8, driving the funnel 4 to move forward or backward in the horizontal direction. At the same time, the two sliders 10 slide on the limit rod 7 to keep the funnel 4 moving smoothly. According to the position of grouting required, the position of the funnel 4 is accurately adjusted until the ideal grouting point is reached. When the funnel 4 reaches the designated position, it is poured out through the pouring hopper 12, and the grouting material flows out of the pouring hopper 12 and flows evenly into the target area. The concrete drops evenly from high to low, avoiding the occurrence of vacancies inside the concrete when pouring the foundation. Moreover, the device can work normally even on rainy days, without unevenness, ensuring the stability of each layer of the foundation.

[0053] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
