[0019] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present disclosure. Rather, they are merely examples of devices consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0020] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, this embodiment proposes an adjustable foundation micropile driving device, including a reaction frame 1, a threaded hole is opened on the upper surface of the reaction frame 1, and an assembly bolt for fixing a manual hoist 2 is passed through the internal thread of the threaded hole. The bottom of the manual hoist 2 is hoisted with a lifting ring 3 through a hook, and the lower surface of the lifting ring 3 is fixedly connected to a reaction beam 4. Through the setting of the manual hoist 2, it is more labor-saving and convenient for personnel to adjust the height of the reaction beam 4 later, and the difficulty of operation is reduced. A top iron 5 is provided on the lower surface of the top iron 5, and a hydraulic jack 6 is provided on the lower surface of the top iron 5. Both the top iron 5 and the hydraulic jack 6 are placeable, and whether to use the top iron 5 as an auxiliary can be considered according to the pile driving height and the position of the pile body 12.

[0022] There are holes on both sides of the reaction frame 1, and A bolts for fixing the push rod 7 are passed through the inside of the holes. When the hydraulic jack 6 is started, the push rod 7 is used to resist the reaction beam 4, so that the hydraulic jack 6 can smoothly push the pile body 12 downward to move, and the position of the push rod 7 can be adjusted by removing the A bolt to control the position of the reaction beam 4.

[0023] A support 8 is welded to the bottom end of the reaction frame 1, and an embedded bolt 9 is inserted into the interior of the support 8. The top of the embedded bolt 9 is threadedly connected with a hexagonal nut. By directly embedding the bolt 9, the installation support of the support 8 and the reaction frame 1 is more stable, and the integrated type has a long service life and is not easy to be damaged, which is convenient for turnover.

[0024] The bottom of the embedded bolt 9 is fixedly connected to a base 10, and a pile hole is opened in the middle of the base 10. The interior of the pile hole is fixedly connected to an embedded sleeve 11. The embedded sleeve 11 can be cast according to the pile diameter of the pile body 12 to keep the pile body 12 vertical when it descends and improve the molding degree of the pile body 12.

[0025] The embedded casing 11 is internally plugged with a pile body 12, the top of the pile body 12 is against the bottom of the hydraulic jack 6, and the bottom of the pile body 12 is provided with a pointed cone for easy insertion into the ground. After a pile body 12 is inserted to a suitable position, the hydraulic jack 6 can be retracted and then put into the pile body 12. This operation is repeated to keep the depth of the pile body 12 meeting the requirements.

[0026] A hydraulic pipe 13 is fixedly mounted on the surface of the hydraulic jack 6 , and a numerically controlled oil pump 14 is fixedly mounted on one end of the hydraulic pipe 13 .

[0027] Specifically, when the adjustable foundation micro-pile driving device is working / in use: when in use, the device is moved to the pile driving position, and then the pile body 12 is inserted into the base 10, and then the hydraulic jack 6 and the top iron 5 are placed. By starting the hydraulic jack 6 and the reaction force of the reaction beam 4, the pile body 12 is pressed into the soil layer to achieve the pile driving operation, which solves the problem that traditional pile drivers are difficult to enter the construction site and there are many hidden dangers in manual digging, which makes it difficult for the pile body to meet the subsequent construction requirements and consumes more time and manpower, thereby greatly improving the efficiency of indoor space pile foundation construction.

[0028] The electrical components appearing in this article are all connected to an external main controller and 220V AC power, and the main controller can be a conventional known device that controls a computer, etc. The specific implementation method of this disclosure omits the detailed description of known functions and known components.
