Description

Technical Field

[0001] This utility model relates to the field of cast-in-place pile technology, specifically a novel device for mud-wall cast-in-place piles. Background Technology

[0002] Currently, traditional mud-wall cast-in-place pile devices have many shortcomings during construction. First, the existing devices have a relatively complex structural design, resulting in cumbersome operation procedures. Workers need to undergo extensive training to master the devices, which not only increases labor costs but also reduces overall construction efficiency. Second, due to the large size of the equipment and the inflexibility of its moving parts, the transportation and positioning of the device are time-consuming when operating in narrow or complex terrain, affecting the project progress.

[0003] Therefore, in response to the above problems, we have developed a new type of device for mud wall grouting piles. This device solves the tedious work of manual grouting required for mud wall grouting and can also be used as a high-pressure jet grouting pile. This device can be used for mud wall grouting piles, high-pressure jet grouting piles, and cement mixing. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a novel device for mud-wall grouting piles, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel device for mud wall grouting piles, comprising a liquid tank and a chassis, wherein the liquid tank is installed at the upper rear end of the chassis, a submersible pump is installed inside the liquid tank, the liquid tank is connected to a fluid delivery pipe through the submersible pump, the fluid delivery pipe is connected to a pressurizing device, a delivery rod is connected to the lower end of the pressurizing device, and a high-pressure drill bit is installed at the lower end of the delivery rod.

[0006] Preferably, a mast is provided at the front end of the chassis, and pipe clamps are arranged vertically on the surface of the mast.

[0007] Preferably, the fluid delivery pipe is mounted and fixed to the mast using a pipe clamp.

[0008] Preferably, a power head is also provided on the mast of the chassis.

[0009] Preferably, the booster is installed on the top inner side of the power head, and the conveying rod is installed on the bottom inner side of the power head.

[0010] Preferably, a lifting motor is also installed above the power head, and the power head slides on the mast via the lifting motor.

[0011] Preferably, the bottom of the high-pressure drill bit has several bullet heads uniformly installed in a ring shape.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model develops a novel device for mud wall grouting piles. The chassis provides energy to the entire equipment and can move the entire equipment. A liquid tank is installed at the rear of the chassis, and a submersible pump is installed in the liquid tank. The submersible pump delivers liquid to the pressurization equipment through a fluid delivery pipe. The high-pressure liquid inside is sent to the high-pressure drill bit through a delivery rod. The high-pressure liquid is sprayed out while the high-pressure drill bit rotates and drills the hole. In summary, this utility model is simple to operate and solves the tedious work of manual injection for mud wall protection. While general equipment requires manual injection of liquid, this equipment automatically delivers liquid to the underground borehole through a liquid pipe and can move on its own, saving a lot of manpower and almost completely replacing it with machinery.

[0013] Meanwhile, this equipment can be used for various construction processes, such as mud wall grouting piles, high-pressure jet grouting piles, and cement mixing. It is versatile and can input liquids with pressures ranging from low to high 30 MPa, and can transport liquids such as water, cement, and mud. Attached Figure Description

[0015] The diagram shows the following labels: 1. Liquid tank; 2. Chassis; 3. Fluid delivery pipe; 4. Lifting motor; 5. Pressurization equipment; 6. Power head; 7. Delivery rod; 8. High-pressure drill bit. Detailed Implementation

[0016] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model. Example 1

[0017] like Figure 1 As shown, this embodiment discloses a novel device for mud wall grouting piles, including a liquid tank 1 and a chassis 2. The liquid tank 1 is installed at the upper rear end of the chassis 2. A submersible pump is installed inside the liquid tank 1. The liquid tank 1 is connected to a fluid delivery pipe 3 through the submersible pump. The fluid delivery pipe 3 is connected to a pressurizing device 5. A delivery rod 7 is connected to the lower end of the pressurizing device 5. A high-pressure drill bit 8 is installed at the lower end of the delivery rod 7.

[0018] In this embodiment, the liquid tank 1 can store water, mud, cement, etc., and is equipped with a submersible pump. The submersible pump delivers the liquid to the pressurization device 5 through the fluid delivery pipe 3. The pressurization device 5 can pressurize the liquid to 30 MPa, and the high-pressure liquid inside is delivered to the high-pressure drill bit 8 through the delivery rod 7. At the same time, while the high-pressure drill bit 8 is rotating and drilling, high-pressure liquid is sprayed out. If the process is high-pressure jet grouting pile, the fluid can be replaced with cement. If the process is cement mixing, the liquid does not need to be pressurized.

[0019] In this embodiment, the high-pressure drill bit 8 is equipped with a bullet head, which can cut through harder gravel geological layers. If it is necessary to drill in a harder geological layer, the fluid can be replaced with water, which can cool the drill bit during the drilling process.

[0020] In this embodiment, the booster device 5 is installed inside the power head 6. The power head 6 can drive the booster device 5 to rotate. At the same time, a lifting motor 4 is installed above the power head 6, which can move the power head 6 up and down. Together with the rotation of the power head 6, the purpose of drilling is achieved. Example 2

[0021] like Figure 1 As shown, this embodiment discloses a novel device for mud wall grouting piles, including a liquid tank 1 and a chassis 2. The liquid tank 1 is installed at the upper rear end of the chassis 2. A submersible pump is installed inside the liquid tank 1. The liquid tank 1 is connected to a fluid delivery pipe 3 through the submersible pump. The fluid delivery pipe 3 is connected to a pressurizing device 5. A delivery rod 7 is connected to the lower end of the pressurizing device 5. A high-pressure drill bit 8 is installed at the lower end of the delivery rod 7.

[0022] In this embodiment, the chassis 2 provides power to the entire device and can move the entire device. A mast is provided at the front end of the chassis 2. Pipe clamps are arranged vertically on the surface of the mast. The fluid delivery pipe 3 is installed and fixed on the mast through the pipe clamps. A power head 6 is also provided on the mast of the chassis 2. A pressurization device 5 is fixedly installed on the top inner side of the power head 6, and a delivery rod 7 is coaxially installed on the bottom inner side of the power head 6.

[0023] In this embodiment, a booster device 5 is fixedly installed on the top inner side of the power head 6, and a conveying rod 7 is coaxially installed on the bottom inner side of the power head 6; a lifting motor 4 is installed above the power head 6, and the power head 6 is driven by the lifting motor 4 to achieve precise up and down sliding along the guide rail preset on the surface of the mast; the fluid conveying pipe 3 is firmly installed by the pipe clamps distributed on the mast and keeps its direction straight to ensure the stability of fluid conveying; several hard alloy bullets are uniformly welded in a ring at the bottom of the high-pressure drill bit 8 to enhance the rock breaking ability of the drill bit.

[0024] Working principle: Once the device is moved to the construction location, the operator starts the power system of chassis 2 to provide energy to the entire equipment; During filling, firstly, the submersible pump in the liquid tank 1 starts working to draw out the stored liquid through the fluid delivery pipe 3; the fluid delivery pipe 3 is fixed by the pipe clamp on the mast to ensure a stable delivery path; The liquid then enters the pressurization device 5, which can adjust the pressure to a range of 0-30MPa according to process requirements, for example, pressurizing to 30MPa in high-pressure jet grouting piles; The pressurized high-pressure liquid flows through the conveyor rod 7 and reaches the high-pressure drill bit 8; at the same time, the power head 6 slides up and down along the mast under the drive of the lifting motor 4, and drives the conveyor rod 7 and the high-pressure drill bit 8 to rotate. The cemented carbide bullet at the bottom of the high-pressure drill bit 8 cuts through the geological layers during rotation, forming a borehole; During drilling, high-pressure fluid is ejected from the drill bit: If used for mud-wall cast-in-place piles, the sprayed mud can immediately form a protective layer. If used for high-pressure jet grouting piles, the cement slurry mixes with the soil under high pressure to form a solidified body; if used for cement mixing, the low-pressure liquid promotes the uniform mixing of cement and soil. The fluid spraying also cools and lubricates the drill bit, which can improve drilling efficiency, especially in hard rock formations. After drilling is completed, the lifting motor 4 drives the power head 6 to retract the drill bit, and the chassis 2 can be easily moved to the next work position to achieve continuous operation, significantly improve construction efficiency and reduce manual intervention.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
