Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a high-pressure jet grouting pile correction device. Background Technology

[0002] High-pressure jet grouting piles use high-pressure rotating nozzles to inject cement grout into the soil layer and mix it with the soil to form a continuous, overlapping cement-reinforced structure. Construction requires less land, produces less vibration and noise, but it can easily pollute the environment and is more expensive. It is not suitable for special soil types where the injected grout cannot solidify.

[0003] High-pressure jet grouting piles are formed by drilling to the designed depth with a drill rod and then simultaneously lifting and jetting grout. During construction, improper operation, mechanical vibration, or displacement can easily cause the drill rod to deviate, affecting the quality of the pile. To solve this problem, a deviation correction device is needed. Existing deviation correction devices work by inserting a correction ring into the drill rod, thus correcting the deviation during drill rod use. However, because the correction ring in existing deviation correction devices can only be used with drill rods of one size, the flexibility of existing deviation correction devices is relatively low. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a high-pressure jet grouting pile correction device to solve the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: a high-pressure jet grouting pile correction device, including a correction ring. The outer ring surface of the correction ring has multiple adjustment ports in an annular structure. Each adjustment port has an adjustment column. One end of each adjustment column extends into the central hole of the correction ring and has an installation groove. Each installation groove has a pressure sensor installed in it. Each pressure sensor has a universal ball installed on its detection end. The surface of each adjustment column is recessed to form multiple positioning grooves in an arc shape. The surface of the correction ring has an annular groove communicating with the adjustment port. A positioning ring is provided in the annular groove, and one end of the positioning ring is inserted into the corresponding positioning groove.

[0006] As a preferred technical solution, a fixing plate is installed on the side of the correction ring away from the positioning ring. The fixing plate has a through hole in the middle that communicates with the center hole of the correction ring. Connecting seats are installed at both ends of the fixing plate, and the connecting seats have multiple screw holes.

[0007] As a preferred technical solution, a rotating ring is installed at one end of the positioning ring, and multiple grips are installed on the surface of the rotating ring in a ring structure.

[0008] As a preferred technical solution, the inner wall of the annular groove is provided with an internal thread, and the outer ring of the positioning ring is provided with an external thread. The positioning ring is connected to the internal thread in the annular groove through the engagement of the external thread.

[0009] As a preferred technical solution, a pipe is installed on the other end of the adjusting column, and the inside of the adjusting column is provided with wiring holes that connect the installation groove and the pipe.

[0010] As a preferred technical solution, the width of the positioning groove is matched with the thickness of the positioning ring.

[0011] As a preferred technical solution, both the adjustment port and the adjustment column have rectangular cross-sections.

[0012] The beneficial effects of this utility model are: This utility model has a simple structure and can change the position of the adjusting column according to the drill rod of different diameters. The movement of the adjusting column drives the pressure sensor and the universal ball, so that it can adapt to drill rods of different diameters. Furthermore, the positioning ring can synchronously position all the adjusting columns and pressure sensors. After the positioning ring rotates upward, the adjusting column can be quickly adjusted along the adjusting port, which increases the convenience of operation. Attached Figure Description

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0020] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0021] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a high-pressure jet grouting pile correction device of this utility model includes a correction ring 1. The outer ring surface of the correction ring 1 has multiple adjustment ports in an annular structure. Each adjustment port is provided with an adjustment column 2. One end of each adjustment column 2 extends into the central hole of the correction ring 1 and is provided with an installation groove. Each installation groove is provided with a pressure sensor 5. Each pressure sensor 5 is provided with a universal ball 6. Multiple positioning grooves 4 in an arc structure are formed by recesses on the surface of the adjustment column 2. The surface of the correction ring 1 is provided with an annular groove 12 that communicates with the adjustment ports. A positioning ring 13 is provided in the annular groove 12. One end of the positioning ring 13 is inserted into the corresponding positioning groove 4.

[0023] In this embodiment, a fixing plate 9 is installed on the side of the correction ring 1 away from the positioning ring 13. The middle of the fixing plate 9 is provided with a through hole 11 that communicates with the center hole of the correction ring 1. Connecting seats 10 are installed at both ends of the fixing plate 9. The connecting seats 10 are provided with multiple screw holes. The connecting seats can be connected to an external bracket, thereby fixing it to the outside of the drilling rig.

[0024] In this embodiment, a rotating ring 7 is installed at one end of the positioning ring 13. Multiple grips 8 are installed on the surface of the rotating ring 7 in a ring structure, which facilitates the rotation of the rotating ring by holding the grips.

[0025] In this embodiment, the inner wall of the annular groove 12 is provided with an internal thread, and the outer ring of the positioning ring 13 is provided with an external thread. The positioning ring 13 is connected to the internal thread in the annular groove 12 through the external thread.

[0026] In this embodiment, a pipe 3 is installed on the other end of the adjusting column 2. The inside of the adjusting column 2 is provided with wiring holes that connect the mounting groove and the pipe 3. The wires on the pressure sensor can pass through the wiring holes and pipes to extend to the outside and connect to the display device, so that the staff can know in time whether there is a deviation.

[0027] In this embodiment, the width of the positioning groove 4 is matched with the thickness of the positioning ring 13, so that after the positioning ring is inserted into the positioning groove, the adjusting column can be positioned back and forth, avoiding movement along the adjusting port and increasing stability.

[0028] In this embodiment, both the adjustment port and the adjustment column 2 have rectangular cross-sections, which allows the adjustment column to move only along the front and back of the adjustment port, thus avoiding rotation and increasing stability.

[0029] During use, the position of the adjusting column can be adjusted according to the diameter of the drill rod. During adjustment, the rotating ring is rotated directly by gripping the rod. The rotation of the rotating ring drives the positioning ring, allowing the positioning ring to move out of the positioning groove. After losing the limit of the positioning ring, the adjusting column can move along the adjustment port. The movement of the adjusting column drives the pressure sensor and the universal ball, allowing multiple universal balls to combine to form an annular detection area that matches the diameter of the drill rod. After moving into position, the positioning ring can be rotated in the opposite direction, allowing the positioning ring to be inserted into the corresponding positioning groove, thereby positioning the adjusting column, pressure sensor, and universal ball, greatly facilitating operation and making it easier to adjust the pressure sensor internally and externally.

[0030] In this system, if the drill rod deviates, it will come into contact with the universal ball on one side. The rotation of the universal ball prevents the drill rod from making direct rigid contact with the correction ring. The pressure applied to the universal ball can be immediately detected by the pressure sensor, thus enabling timely correction when the drill rod is in use.

[0031] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
