[0002] As is well - known, whether it is industrial or civil construction, or bridge and tunnel engineering, etc., it often cannot do without foundation and sub - foundation treatment. For foundations and sub - foundations, pile foundations are sometimes used. There are many common forms of pile foundations. Among them, long - helix grouting cast - in - place concrete piles under different geological conditions and current grouting piles using concrete instead of mixture (abbreviated as CFG piles) are more commonly used; long - helix grouting cast - in - place concrete piles and concrete grouting piles are widely used in high - rise buildings or railway high - speed bridge piers due to advantages such as fast operation progress and high pile - forming quality. At present, after the above - mentioned two types of piles are drilled to the design elevation, the construction link is to lift the drill and pour concrete.

However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0024] Please refer to Figures 1-4 , the present utility model provides a technical solution: a construction device for long spiral drilled cast-in-place piles, including a ground fixing device 1 and a frame 2. A power device 5 is provided on the front surface of the frame 2. An installation plate 7 is fixedly connected to the outer surface of one side of the power device 5, and a travel switch 8 is provided on the front surface of the installation plate 7; a moving assembly 3 is fixedly connected to the outer surface of the frame 2. The moving assembly 3 includes a fixing frame 301. A fixing plate 302 is fixedly connected to the front surface of the fixing frame 301. An electric telescopic rod 303 is fixedly connected to the rear surface of the fixing plate 302. The telescopic end of the electric telescopic rod 303 is fixedly connected to a moving plate 304. A plurality of blocking rods 305 are equidistantly and fixedly connected to the front surface of the moving plate 304.

[0025] As Figure 1 shown, the fixing frame 301 is fixedly connected to the outer surface of one side of the frame 2. The frame 2 is fixedly connected to the top of the ground fixing and ground fixing device 1. By fixedly connecting the frame 2 with the ground fixing device 1, a supporting effect is achieved.

[0026] As Figures 1-3 shown, a long-arm screw drill rod 9 is provided at the bottom of the power device 5. The long-arm screw drill rod 9 is in communication with the power device 5, which facilitates driving the long-arm screw drill rod 9 to rotate and drill holes under the action of the power device 5. During the process of lifting the drill, concrete is injected downward through the hollow interior of the long-arm screw drill rod 9.

[0027] As Figures 1-2 shown, a grouting pipe 10 is provided on the front surface of the power device 5. The grouting pipe 10 is in communication with the power device 5, which facilitates the concrete in the pump truck to enter the long-arm screw drill rod 9 through the grouting pipe 10 when the grouting pipe 10 is connected to an external pump truck.

[0028] As Figures 2-3 and Figure 5 shown, slide rails 4 are symmetrically and fixedly connected to the front surface of the frame 2. Chute grooves 6 are symmetrically formed on the rear surface of the power device 5. The chute grooves 6 are in a matching setting with the slide rails 4, which facilitates the power device 5 to slide synchronously on the outer surface of the slide rails 4 through the chute grooves 6 formed on its surface during the up and down movement of the power device 5 driven by an external power, playing a role of limiting.

[0029] As Figure 4As shown, the telescopic end of the electric telescopic rod 303 slides through the outer surface of the fixed plate 302, and the outer surfaces of multiple blocking rods 305 all slide through the outer surface of the fixed frame 301, facilitating the synchronous sliding of the multiple blocking rods 305 between the inner walls of the fixed frame 301 under the telescopic action of the electric telescopic rod 303.

[0030] As Figure 4 shown, a plurality of guide rods 306 are fixedly connected to the rear surface of the moving plate 304 at equal intervals, and the outer surfaces of the plurality of guide rods 306 all slide through the outer surface of the fixed plate 302. When the moving plate 304 moves back and forth, the plurality of guide rods 306 fixedly connected to its rear surface slide synchronously in the inner wall of the fixed plate 302, playing a guiding role.

[0031] Usage method and working principle of this device: During the pressure grouting pile, the external power drives the power device 5 to descend, and the power device 5 drives the long-arm screw drill rod 9 to descend to drill the working site. The chutes 6 symmetrically arranged on the rear surface of the power device 5 slide synchronously along the outer surfaces of the two slide rails 4 arranged on the front surface of the frame 2, playing a limiting role. After the drilling is completed, the electric telescopic rod 303 extends, and the telescopic end of the electric telescopic rod 303 slides forward in the inner wall of the fixed plate 302, pushing the moving plate 304 forward. The plurality of guide rods 306 fixedly connected to the rear surface of the moving plate 304 slide synchronously in the inner wall of the fixed plate 302, playing a limiting role, keeping the moving plate 304 moving forward smoothly, and further enabling the plurality of blocking rods 305 to slide through the outer surface of the fixed frame 301 and extend outward. The power device 5 drives the long-arm screw drill rod 9 to move upward for the drill lifting action. The toggle lever of the travel switch 8 fixed to the power device 5 through the mounting plate 7 will first be toggled and triggered by the blocking rod 305 in the lowermost position. After the travel switch 8 is triggered and reset, it will send an instruction to the external driving device to stop lifting the power device 5. At this time, the external pump truck starts to work, and conveys the concrete to the hollow long-arm screw drill rod 9 through the pressure grouting pipe 10. Under the action of pressure, the concrete breaks through the one-way switch at the bottom of the long-arm screw drill rod 9 and starts to inject the concrete into the drilled hole. Repeat the above pressure grouting steps. When the travel switch 8 rises, the toggle lever of the travel switch 8 will be sequentially toggled and triggered by the plurality of blocking rods 305 from bottom to top, making the lifting distance of each drill fixed, ensuring the effective progress of the construction link of lifting the drill and pouring concrete, avoiding the need for operators to observe the lifting distance of the drill in real time, and having a high degree of automation.

[0032] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the content of the technical solution of the present utility model still fall within the protection scope of the technical solution of the present utility model.
