Description

Technical Field

[0001] This application relates to the field of geotechnical engineering technology, and in particular to a high-torque jet grouting and mixing pile construction device. Background Technology

[0002] Foundation refers to the soil or rock mass that supports the foundation of a building. Jet grouting is a commonly used method in foundation treatment, which involves rotating and jetting cement grout to mix with the soil to form a consolidated body, thereby improving the bearing capacity of the foundation.

[0003] Currently, traditional jet grouting pile construction equipment rotates the drill bit by rotating the drill rod during operation. However, traditional jet grouting pile construction equipment cannot level the drilling rig chassis in real time, which can easily lead to borehole tilting. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a high-torque jet grouting and mixing pile construction device, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0005] To achieve the above objectives, this application adopts the following technical solution: a high-torque jet grouting pile construction device, comprising a jet grouting pile construction platform, wherein four balancing mechanisms are provided on the surface of the jet grouting pile construction platform, the four balancing mechanisms being symmetrically distributed on the surface of the jet grouting pile construction platform, each balancing mechanism comprising a fixing block, the fixing block being fixedly connected to the jet grouting pile construction platform, a jack being fixedly connected inside the fixing block, a support block being fixedly connected to the telescopic end of the jack, an inclination sensor being fixedly connected to one side of the fixing block, a vibration mechanism being provided on one side of the jet grouting pile construction platform, a ground-penetrating radar being fixedly connected to the top of the jet grouting pile construction platform, and a receiving antenna and a transmitting antenna being provided on the outside of one side of the jet grouting pile construction platform, the receiving antenna and the transmitting antenna being symmetrically distributed on the surface of the jet grouting pile construction platform, and a height adjustment mechanism being provided at the top of each receiving antenna and the transmitting antenna.

[0006] In a preferred embodiment, the vibration mechanism includes a support rod, which is fixedly connected to the jet grouting pile construction platform. A second motor is fixedly connected inside the support rod, and a rotating rod is fixedly connected to the output end of the second motor. A striking block is fixedly connected to the surface of the rotating rod.

[0007] By adopting the above technical solution, the second motor is fixed by the support rod, and the output end of the second motor rotates to drive the rotating rod to rotate. The rotating rod then drives the striking block to rotate, and the striking block then strikes the drill rod of the jet grouting pile construction platform to make the drill rod vibrate, which makes it easier to pull the drill rod out of the drill pit. This method can better make the drill rod vibrate and facilitate the removal of the drill rod from the drill pit.

[0008] In a preferred embodiment, both the receiving antenna and the transmitting antenna are electrically connected to the ground-penetrating radar.

[0009] By adopting the above technical solution, with both the receiving and transmitting antennas electrically connected to the ground-penetrating radar, and the transmitting and receiving antennas working together with the ground-penetrating radar to detect underground obstacles, adjust the pile position, and avoid vibrations caused by sudden changes in drilling resistance, it is possible to better detect underground obstacles, adjust the pile position, and avoid vibrations caused by sudden changes in drilling resistance.

[0010] In a preferred embodiment, the height adjustment mechanism includes a sleeve rod, which is fixedly connected to the jet grouting pile construction platform. A motor is fixedly connected to the top of the sleeve rod, and a threaded rod is fixedly connected to the output end of the motor. A movable rod is threadedly connected to the external thread of the threaded rod, and the movable rod is slidably connected to the sleeve rod. A receiving antenna is fixedly connected to the bottom of the movable rod.

[0011] By adopting the above technical solution, the output end of motor one rotates to drive the threaded rod to rotate, and the rotation of the threaded rod causes the moving rod to slide inside the sleeve rod. The movement of the moving rod then drives the receiving antenna to move, thereby adjusting the distance between the receiving antenna and the ground. This allows for better adjustment of the distance between the receiving antenna and the ground.

[0012] In a preferred embodiment, the tilt sensor is electrically connected to the jack.

[0013] By adopting the above technical solution, the tilt sensor is electrically connected to the jack, and the tilt sensor controls the jack's switch, which allows for better control of the jack's operation.

[0014] In a preferred embodiment, a controller is fixedly connected to the surface of the jet grouting pile construction platform, and the controller is electrically connected to a motor.

[0015] By adopting the above technical solution, the controller is electrically connected to the second motor, and the controller controls the switch of the second motor, which can better control the switch of the second motor.

[0016] In a preferred embodiment, a protective layer, which is a rubber component, is fixedly connected to the surface of the striking block.

[0017] By adopting the above technical solution, a protective layer is fixedly connected to the surface of the striking block, and the striking block is protected by the protective layer, thus extending the service life of the striking block and providing better protection for it.

[0018] The beneficial effects of this application are: 1. This high-torque jet grouting and mixing pile construction device, by setting up jacks, fixing blocks, tilt sensors, and support blocks, uses fixing blocks to secure the jacks, and then the extension and retraction of the jacks to move the support blocks. The support blocks then contact the ground to level the jet grouting and mixing pile construction platform. The tilt sensors detect the flatness of the jet grouting and mixing pile construction platform in real time. This avoids the problem of traditional jet grouting and mixing pile construction devices being unable to level the drilling rig chassis in real time, which easily leads to borehole tilting, thus improving practicality.

[0019] 2. This high-torque jet grouting pile construction device, by setting up a support rod, a second motor, a rotating rod, and a striking block, fixes the second motor to the support rod. The output end of the second motor rotates, driving the rotating rod to rotate, which in turn drives the striking block to rotate. The striking block then strikes the drill rod of the jet grouting pile construction platform, causing the drill rod to vibrate. This avoids the problem in traditional jet grouting pile construction devices where residual cement slurry forms a solidified layer on the drill rod surface when it is pulled out of the drill pit, increasing frictional resistance and making it difficult to pull out the drill rod, thus improving practicality.

The tilt sensor 23 then detects the flatness of the jet grouting pile construction platform 1 in real time. After the construction is completed, the motor 42 is fixed by the support rod 41.
