Description

Technical Field

[0001] This utility model relates to the field of pile driver construction technology, specifically a positioning support base for the construction of a three-axis cement mixing pile driver. Background Technology

[0002] The three-axis cement mixing pile machine is a type of long spiral pile machine. It has three spiral drilling holes. During construction, the three spiral drilling holes are drilled downwards simultaneously. It is an effective form of soft soil treatment. The mixing pile machine sprays cement into the soil and mixes it thoroughly, causing a series of physical and chemical reactions between the cement and the soil, which hardens the soft soil and improves the foundation strength.

[0003] Existing cement mixing piles mostly involve placing the equipment directly on the ground and supporting it with the equipment shell. This structure is relatively fixed, has low applicability, and is prone to damage during use, affecting user experience. In addition, the existing support bases are mostly unstable, and the verticality of the mixing pile needs to be precisely controlled during the use of the triaxial cement mixing pile machine to ensure drilling effect. Furthermore, the existing positioning support bases for the construction of triaxial cement mixing pile machines can only perform simple installation of the pile machine and cannot move the pile machine. Moreover, their applicability is limited, resulting in low practicality. Summary of the Invention

[0004] To address the shortcomings of the existing technology, this utility model provides a positioning support base for the construction of a three-axis cement mixing pile, which allows the pile driver to be moved, controls the verticality of the mixing pile to ensure drilling effect, forms a stable support, and is easy to use.

[0005] The technical solution provided by this utility model is as follows: a positioning support base for the construction of a three-axis cement mixing pile machine, including a bracket, a support plate connected to the surface of the bracket, multiple sets of positioning plates fixedly installed on the surface of the support plate, multiple sets of connection holes opened inside the positioning plate, an installation frame welded to the outer wall of the bracket, a total station installed on the installation frame, connecting columns fixedly installed on both sides of the bracket, a support column is provided on the surface of the connecting column through a hydraulic cylinder, a sleeve plate is fitted on the outer wall of the support column, and the sleeve plate is fixedly connected to the outer wall of the connecting column.

[0006] Furthermore, the connecting columns and the supporting columns are vertically distributed, and the connecting columns are symmetrically arranged at both ends of the bracket.

[0007] Furthermore, a support base plate is fixedly connected to the bottom end of the support column.

[0008] Furthermore, a rubber pad is connected to the bottom end of the support base plate via a telescopic spring, and the two ends of the rubber pad are connected to the support base plate via bolts.

[0009] Furthermore, a steel plate is connected to the bottom end of the rubber pad.

[0010] Furthermore, a guide post is provided through the telescopic spring, and the upper end of the guide post movably passes through the supporting base plate.

[0011] Furthermore, the bracket has an "II" shaped structure, and movable wheels are connected to both sides of the bracket.

[0012] The beneficial effects of this utility model are:

[0013] (1) In this utility model, by setting up an installation frame and a total station on one side of the support, the total station can be fixedly installed at the bottom of the base, which is convenient for checking and adjusting the vertical angle between the drill rod and the ground, ensuring that the verticality deviation is not greater than 1 / 300. At the same time, it is convenient to observe and record the drilling depth of the drill rod when it enters the soil, ensuring that the length of the mixing pile is not less than the designed pile length, ensuring the construction verticality of the three-axis cement mixing pile machine, ensuring the construction quality of the pile machine, and ensuring that the structure is simple and convenient.

[0014] (2) In this utility model, by setting the bottom of the support with moving wheels, the base can drive the pile driver to move flexibly on the construction site, which is convenient for positioning the pile driver.

[0023] Reference Figures 1-4A positioning support base for a three-axis cement mixing pile driving machine includes a bracket 1, a support plate 2, a positioning plate 3, a connecting hole 4, a connecting column 5, a sleeve plate 6, a support column 7, a hydraulic cylinder 8, a support base plate 9, a moving wheel 10, an installation frame 11, a total station 12, a telescopic spring 13, a rubber pad 14, and a steel plate 15. The bracket 1 has an "II" shaped structure and is welded from steel. Considering the stability of the pile driver, a support plate 2 is connected to the surface of the bracket 1. In order to achieve the installation effect of the pile driver on the surface of the support plate 2, multiple sets of positioning plates 3 are fixedly installed on the surface of the support plate 2 to facilitate the positioning plates 3 to limit the pile driver on the surface of the support plate 2. At the same time, the positioning plates 3... Multiple sets of connection holes 4 are opened inside the support plate 2 to facilitate the connection of the pile driver with the positioning plate 3 through the connection holes 4. Taking a real estate triaxial cement mixing pile driver of model JB180 as an example, positioning plates 3 can be set on both sides of the support plate 2 to facilitate the positioning plates 3 to limit the pile driver on both sides. At the same time, the bottom of the pile driver is tied to the positioning plate 3 through the connection holes 4 to ensure the installation stability of the pile driver. In addition, considering the movement effect and mobility of the pile driver on the construction site after installation, moving wheels 10 are connected to both sides of the support plate 1 to facilitate the base to drive the pile driver to move through the moving wheels 10, which is conducive to realizing large-area construction of the pile driver and improving the construction efficiency of the pile driver.

[0024] The verticality of the three-axis cement mixing pile machine during operation is a key challenge in pile construction. After the support 1 moves the pile machine to the precise position, the pile machine is positioned smoothly and safely. An installation frame 11 is welded to the outer wall of the support 1, and a total station 12 is installed on the surface of the installation frame 11. The model of the total station 12 is CX-52. In order to improve the accuracy of the test, two total stations 12 can be set at a 90° angle. The total station 12 can check and adjust the vertical angle between the drill rod and the ground to ensure that the verticality deviation is no more than 1 / 300. At the same time, it is convenient to observe and record the drilling depth of the drill rod when it enters the soil, ensuring that the length of the mixing pile is not less than the designed pile length.

[0025] Considering the stability of the support frame 1 at the pile driver construction site, a connecting column 5 is fixedly installed on the outer wall of the support frame 1, and the connecting column 5 is symmetrically arranged at both ends of the support frame 1. In order to support the support frame 1, a support column 7 is telescopically installed on the surface of the connecting column 5 through a hydraulic cylinder 8. Under the action of the hydraulic cylinder 8, the support column 7 can flexibly move up and down on one side of the connecting column 5, and the connecting column 5 and the support column 7 are vertically distributed to ensure the support effect of the support column 7 on the ground. At the same time, in order to ensure the movement path of the support column 7, a sleeve plate 6 is fitted on the outer wall of the support column 7, and the sleeve plate 6 is fixedly connected to the outer wall of the connecting column 5, which facilitates the lifting and lowering of the support column 7 inside the sleeve plate 6. Through this arrangement, the support column 7 can stably support the support frame 1 on both sides under the action of the hydraulic cylinder 8, ensuring the stability of the support frame 1 on the ground. Moreover, by extending the support column 7 to the outside of the support frame 1 through the connecting column 5, the support range of the support column 7 is increased, which is beneficial for the surface of the support frame 1 to be applicable to different types of pile drivers, thus improving the applicability of the base.

[0026] In one embodiment, since the base may be used on soft ground, in order to enhance the support effect of the support column 7, a support base plate 9 is fixedly connected to the bottom end of the support column 7, and the support base plate 9 is connected between the two sets of support columns 7, which increases the bottom support area of ​​the base. In order to improve the stability of the support base plate 9, a rubber pad 14 is connected to the bottom end of the support base plate 9 through a telescopic spring 13, and the two ends of the rubber pad 14 are connected to the support base plate 9 by bolts. Under the action of the telescopic spring 13, the rubber pad 14 can adapt to uneven ground at the bottom of the support base plate 9, ensuring the support effect of the support base plate 9. A guide column runs through the telescopic spring 13, and the upper end of the guide column moves through the support base plate 9 to prevent the telescopic spring 13 from shaking. At the same time, in order to increase the service life and support stability of the rubber pad 14, a steel plate 15 is connected to the bottom end of the rubber pad 14, ensuring the bottom support strength of the support base plate 9 and providing good protection for the rubber pad 14.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
