[0002] PHC pipe piles, that is, prestressed high-strength concrete pipe piles, the hammer pile driving method mainly utilizes the instantaneous impact mechanical energy of the pile hammer when it falls, to overcome the side wall friction resistance of the pile body and the resistance of the soil layer at the pile end, so that its static equilibrium state is destroyed, causing the pile body to sink and reach a new static pressure equilibrium state.

[0003] The PHC pipe pile hammering construction process also has problems such as the difficulty in controlling the pile top elevation and the low first-time qualified rate of pile sinking. In addition, due to the large deviation of the pile top elevation, it is often necessary to cut or connect the piles. During the use of a single guiding pile delivery device, it is difficult to flexibly adjust the spacing of the device according to the needs of pile foundation burial, which affects the efficiency of pipe pile hammering.

A limit mechanism is arranged directly above the displacement mechanism. The limit mechanism adjusts and controls the height of the limit according to the size of the pipe pile and the need for pile cutting, so as to meet the requirements of docking and pile delivery of multiple groups of tank piles.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figures 1 to 5 As shown, a pile delivery device for hammer-driven pile driving of PHC pipe piles comprises a positioning frame 1. A displacement mechanism 5 is arranged on the outer side of the positioning frame 1. The displacement mechanism 5 adjusts the position of the guide frame 4, and then adjusts the distance of the pile driving according to the spacing of the pile foundation. A limiting mechanism 7 is arranged directly above the displacement mechanism 5. The limiting mechanism 7 adjusts and controls the height of the limit according to the size of the pipe pile and the demand for pile cutting, so as to meet the requirements of docking and pile delivery of multiple groups of tank piles.

[0023] In this embodiment, the displacement mechanism 5 includes a side guide groove 2, a vertical cone 3, a guide frame 4 and a positioning hole 12. The side guide groove 2 is symmetrically arranged on both sides of the positioning frame 1. The bottom end of the positioning frame 1 is symmetrically provided with a vertical cone 3. The outer sides of the positioning frame 1 and the guide frame 4 are penetrated by a positioning hole 12. The bottom end of the guide frame 4 is positioned by the vertical cone 3 to prevent the guide frame 4 from tilting.

[0024] In this embodiment, the guide frame 4 is connected to the arc-shaped bracket 8 through the external threaded column 6 symmetrically arranged at the top, and the arc-shaped bracket 8 is vertically guided by the external threaded column 6 to prevent the arc-shaped bracket 8 from tilting.

[0025] In this embodiment, the limiting mechanism 7 includes an external threaded column 6, an arc-shaped bracket 8, a spring column 9, a rubber disc 10, a feeding plate 11, a rubber ring gasket 13 and an outer groove 15. The external threaded column 6 is symmetrically arranged at the top of the guide frame 4. The outer side of the external threaded column 6 is connected to the rubber disc 10. The outer side of the rubber disc 10 is provided with an outer groove 15. The spring column 9 is symmetrically arranged directly above the rubber disc 10. The top of the spring column 9 is provided with both sides of the bottom end of the arc-shaped bracket 8. The feeding plate 11 is arranged directly above the arc-shaped bracket 8. The top of the feeding plate 11 is connected with a rubber ring gasket 13, and the outer side of the pipe pile is wrapped by the rubber ring gasket 13, thereby increasing the friction of the pipe pile.

[0026] In this embodiment, the rubber disc 10 is connected to the tail end of the spring column 9 through an outer groove 15 symmetrically opened on the surface. The bottom end of the spring column 9 is positioned by the outer groove 15 to avoid displacement of the tail end of the spring column 9 when pressed down.

[0027] In this embodiment, the outer sides of the feed plate 11 and the guide frame 4 are penetrated with feed holes 14, the outer sides of the pipe piles are positioned and guided by the feed plate 11 and the guide frame 4, and the friction of the pipe piles is increased by the rubber ring pad 13.

[0028] The practical application of this PHC pile hammer pile driving device includes the following work contents:

[0029] Step 1: The operator first places the positioning frame 1 directly on the construction land, and presses it into the land through the vertical cone 3 set at the bottom of the positioning frame 1. Through the vertical cone 3, the operator can pull the guide frame 4 to slide the guide frame 4 on the outside of the side guide groove 2 to adjust the position of the pile foundation, and insert the bolts into the inside of the positioning hole 12, and lock the connection between the guide frame 4 and the positioning frame 1 through the bolts;

[0030] Step 2: The operator installs the rubber ring gasket 13 inside the feeding through hole 14 according to the diameter of the pipe pile, and uses bolts to lock the rubber ring gasket 13 and the feeding plate body 11. The operator inserts the pipe pile into the feeding plate body 11 and the guide frame 4 in turn, and positions and guides the pipe pile through the feeding through hole 14 opened on the outside of the feeding plate body 11 and the guide frame 4. It is necessary to hit the top of the pipe pile so that the pipe pile is buried in the ground;

[0031] Step 3: When the pipe pile is vertically pressed, the feeding plate 11 lifts the bottom end of the arc bracket 8 through the spring column 9 arranged below as the pipe pile is pressed down, and decompresses the bottom end of the arc bracket 8 through the spring column 9 arranged through the penetrating spring column 9. At the same time, the rubber disc 10 is used to lift and position the bottom ends of the two groups of spring columns 9 to prevent the spring columns 9 from deflecting or tilting during the pressing process;

[0032] Step 4: During use, the rubber disc 10 can be held and rotated on the outside of the external threaded column 6 to adjust the height of the arc bracket 8, thereby facilitating the adjustment of the docking position of the pipe pile, and the connection of the pipe pile can be positioned through the clamp, and the downward pressure reduction force can be controlled according to the height of the feeding plate 11 and the spring column 9 of the corresponding diameter and length to avoid reducing the hammering force.

[0033] Therefore, the embodiments disclosed above are only illustrative in all aspects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
