However, when encountering hard plastic dense clay soil during the construction of steel sheet piles, it is not possible to directly insert steel sheet piles into the soil.

[0003] The traditional method is to use a spiral drilling rig for pilot drilling, but this method has many problems, such as slow pilot drilling speed, large pilot drilling range which can easily lead to the displacement of steel sheet piles later, and a lot of dust brought out when the pilot drilling is completed, causing pollution.

[0004] Therefore, there is an urgent need for a device and system for drilling holes in hard plastic dense clay layers to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a device and system for pilot drilling in hard plastic dense clay layers, in order to solve the technical problems existing in the prior art where using a spiral drilling rig for pilot drilling results in slow pilot drilling speed, a large pilot drilling range that easily leads to subsequent steel sheet pile displacement, and excessive dust pollution caused by the large amount of dust brought out during the drilling process. 。 The various technical effects of the preferred technical solutions among the many technical solutions provided by this utility model are described in detail below.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] Example 1

[0029] Figure 1 This is a structural schematic diagram of this embodiment, as shown below. Figure 1 As shown, this embodiment provides a device for drilling in hard plastic dense clay layers, including a pile plate 4 and a flow guide 6. In this embodiment, the pile plate 4 is a pilot-hole steel sheet pile for pilot-hole drilling; the flow guide 6 is a seamless steel pipe with water flowing through it, used to soften the soil during pilot-hole drilling, play a lubricating role, reduce pile driving resistance, and enable the pile plate 4 to sink smoothly into the soil layer.

[0030] Specifically, in this embodiment, the pile plate 4 is connected to the pile driver 1 to facilitate drilling at the pilot hole position; the drainage component 6 is fixedly connected to the pile plate 4, and the drainage component 6 has a channel inside, with a nozzle assembly 8 at the end of the channel; the pipeline 5 is a hydraulic hose, one end of which is connected to the drainage component 6, and the other end can be connected to the liquid supply device for supplying liquid to the drainage component 6 through the liquid supply device.

[0031] This device for drilling in hard plastic dense clay layers involves fixing the diversion component 6 to the pile plate 4. The diversion component 6 has an internal channel with a nozzle assembly 8 at the end of the channel. A pipe 5 connects the diversion component 6 and the liquid supply device. When drilling at the drilling location using the pile plate 4, the high-pressure water flow in the nozzle assembly 8 can soften the soil during the drilling process, providing lubrication and greatly reducing the resistance to pile driving. This allows the pile plate 4 to sink smoothly into the soil layer. It is simple and convenient to use and has a good drilling effect.

[0032] As an optional implementation, this embodiment also includes a plurality of evenly distributed fixing structures 7.

[0033] Specifically, the fixing structure 7 uses a steel pipe fixing ring to fix the diversion component 6 to the pile plate 4 along the length of the pile plate 4. The ring structure can better limit the circumference of the diversion component 6 and ensure stable connection.

[0034] As an optional implementation method, Figure 2 This is a structural schematic diagram of the nozzle assembly in this embodiment, as shown below. Figure 2 As shown, the nozzle assembly 8 includes a first nozzle assembly 81, which is coaxially arranged with the guide member 6.

[0035] Figure 3 This is a schematic diagram of the nozzle structure in this embodiment, as shown below. Figure 3 As shown, the nozzle assembly 8 in this embodiment includes a nozzle 10, with multiple small holes 9 at the end of the nozzle 10 to create high pressure when the liquid supplied through the nozzle 10 is pressurized. The high-pressure water flow softens the soil during the pre-drilling process, providing lubrication and significantly reducing pile driving resistance, allowing the pre-drilled sheet piles to smoothly sink into the soil.

[0036] As an optional implementation, the nozzle assembly 8 may further include one or more second nozzle assemblies 82 disposed around the periphery of the first nozzle assembly 81 in order to provide a more uniform high-pressure liquid flow.

[0037] Optionally, two second nozzle assemblies 82 are provided, and the two second nozzle assemblies 82 and the guide member 6 form a Y-shaped structure.

[0038] This configuration allows the end of the diversion component 6 to be set as a fork-shaped nozzle. In this embodiment, three small holes 9 are opened at the end of the nozzle to provide high-pressure water flow, making the soil soften more evenly and avoiding water waste.

[0039] In some embodiments, three second nozzle assemblies 82 may be provided, and the three second nozzle assemblies 82 may form a W-shaped structure.

[0040] Example 2

[0041] Figure 4This is a structural schematic diagram of this embodiment, as shown below. Figure 4 As shown, this embodiment provides a system for drilling holes in stiff plastic dense clay layers. Unlike Embodiment 1, this embodiment, based on the device for drilling holes in stiff plastic dense clay layers in Embodiment 1, further includes a pile driver 1 and a liquid supply device. The pile driver 1 is connected to the pile plate 4, and the liquid supply device is connected to the pipeline 5.

[0042] Specifically, the liquid supply device in this embodiment includes a water truck 2 and a water pump 3 installed inside the water truck 2. The pipeline 5 is connected to the water pump 3, wherein the water pump 3 is a high-pressure water pump.

[0043] By employing this system for pilot holes in hard plastic dense clay layers, the combination of the pilot hole device, the pile driver 1, and the liquid supply device allows high-pressure water flow to soften the soil during the pilot hole process, providing lubrication and significantly reducing pile driving resistance. This enables the pilot hole pile plate 4 to smoothly sink into the soil layer. Furthermore, by installing nozzles, high-pressure water flow can be provided, making the soil softening more uniform and avoiding water waste.

[0044] Example 3

[0045] This embodiment provides a method for drilling holes in stiff plastic dense clay layers, using the system for drilling holes in stiff plastic dense clay layers from Embodiment 2, and includes the following steps:

[0046] S1: Pre-construction preparations, including:

[0047] S11: Process the pile plate and fix the diversion component 6 to the pile plate 4; specifically, process the pile plate 4 of appropriate size before construction, and use the fixing structure 7, i.e., the fixing ring, to fix the diversion component 6 made of seamless steel pipe. The nozzle 10 is welded to the end of the diversion component 6.

[0048] S12: Connecting pipe 5 and draining component 6; specifically, connecting the hydraulic hose to the end of the seamless steel pipe, ensuring the stability of the connection to make it safer and more reliable during use.

[0049] S13: Connect pipeline 5 to the liquid supply device and conduct a pressure test; specifically, this includes connecting the hydraulic hose to the high-pressure water pump, placing the water pump into the water truck 2, and conducting a pressure test.

[0050] S2: Pre-hole construction.

[0051] After the pressure test is passed, the pile driver 1 is used to align the pile sheet 4 with the pilot hole position, and the high-pressure water pump is turned on so that the water flows through the small holes 9 on the nozzle 10 to form a high-pressure water flow to cut the soil, thereby quickly completing the pilot hole. After the pilot hole is completed, the pile driver 1 is used to insert the steel sheet pile.

[0052] Specifically, it includes:

[0053] S21: Align the pile plate 4 with the pilot hole using the pile driver 1;

[0054] S22: Liquid supply, which allows the liquid to enter the nozzle assembly 8 through the guide 6, and the liquid is sprayed out through the nozzle assembly 8 to cut the soil.

[0055] S23: Insert the pile plate 4 through the pilot hole position of pile driver 1;

[0056] S3: Repeat steps S1 and S2 to complete the pilot hole drilling for the hard plastic dense clay layer;

[0057] S4: After completing the pilot hole, pull out the pile sheet 4 and insert the steel sheet pile into the pilot hole.

[0058] Repeat the above process to complete the support construction of the steel sheet piles.

[0059] By adopting the above method, the drilling effect is better, and the offset of the sheet pile is small and the efficiency is high.
