[0022] Specifically, please refer to Figures 1 to 5 , Figure 1 The schematic diagram of the overall cross-sectional structure of the prestressed pipe pile for easy pile delivery provided in the embodiment of the present application is as follows: Figure 2 for Figure 1 The enlarged view at A, Figure 3 for Figure 1 The enlarged view at B, Figure 4 for Figure 3 The enlarged view at C, Figure 5A schematic diagram of the local structure of the earth-breaking component provided in the embodiment of the present application. The prestressed pipe pile 100 for easy pile delivery includes a prestressed pipe pile 110, a buffer component 120 arranged on the top of the prestressed pipe pile 110, a earth-breaking component 130 arranged at the bottom of the prestressed pipe pile 110, and an unearthed pipe 140 arranged between the buffer component 120 and the earth-breaking component 130, wherein the prestressed pipe pile 110 is a prior art and has been fully disclosed, and will not be described in detail here. The buffer component 120 is used to buffer the impact force of the pile driver on the prestressed pipe pile 110 and reduce its hard damage to the prestressed pipe pile 110. The earth-breaking component 130 is used to break the ground and reduce the resistance encountered by the prestressed pipe pile 110 during the falling process. The unearthed pipe 140 is used to suck out part of the soil in the foundation to achieve the purpose of rapid pile delivery. The buffer component 120 includes a compression ring 121, and a first reserved groove 122 matching the prestressed pipe pile 110 is provided at the bottom of the compression ring 121. The compression ring 121 is clamped to the top of the prestressed pipe pile 110 through the first reserved groove 122. The size of the first reserved groove 122 can be designed according to the actual size of the prestressed pipe pile 110. The width of the first reserved groove 122 should be slightly larger than the wall thickness of the prestressed pipe pile 110, so that the compression ring 121 and the prestressed pipe pile 110 can be easily installed and disassembled. The earth-breaking component 130 includes a semicircular connecting platform 131, and a second reserved groove 132 is provided at the top of the connecting platform 131. The second reserved groove 132 is used to connect to the bottom wall of the prestressed pipe pile 110, and its specific structure is similar to the first reserved groove 122. A soil-breaking cone 133 is provided at the bottom, and the soil-breaking cone 133 is used to break the soil at the bottom of the prestressed pipe pile 110 to facilitate the placement of the prestressed pipe pile 110. A connection box 134 is provided on one side of the inner arc of the connection platform 131, and the interior of the connection box 134 has a cavity. A first threaded hole 134a is provided on the top of the connection box 134, and a soil suction port 134b is provided on the side of the connection box 134 away from the connection platform 131. The bottom end of the excavation pipe 140 is connected to the first threaded hole 134a through the first connecting piece 141, and the top end of the excavation pipe 140 is connected to the bottom of the pressure-resistant ring 121 through the second connecting piece 142. The pressure-resistant ring 121 is provided with a through wiring hole 121a. The top of the excavation pipe 140 is connected to an excavation hose 143, and the excavation hose 143 is connected along the wiring hole 121a. 1a penetrates to the outside of the anti-compression ring 121 and is connected to a negative pressure device. During operation, when the pile placement process is relatively slow and the density of the foundation soil is relatively high, a negative pressure device can be connected to the end of the excavation hose 143. After the negative pressure device is turned on, negative pressure can be formed inside the excavation hose 143 and the excavation pipe 140, so that excess soil is successively adsorbed into the excavation pipe 140 and the excavation hose 143 through the soil suction port 134b and discharged to the outer wall, thereby reducing the resistance encountered by the prestressed pipe pile 110 and accelerating the pile placement speed.

[0023] As can be seen from the above, during the working process of the embodiment of the present application, the buffer component 120 and the earth-breaking component 130 are sequentially installed at the top and bottom of the prestressed pipe pile 110, and then the excavation pipe 140 is connected. After the excavation hose 143 is connected to the excavation pipe 140, the end of the excavation hose 143 is led out from the wiring hole 121a. At this time, the prestressed pipe pile 110 is straightened, and a pile driver is used to align the buffer component 120 for hammering. After the earth-breaking component 130 breaks the soil at the bottom of the prestressed pipe pile 110, the prestressed pipe pile 110 falls into the foundation. During the continuous hammering process, the external negative pressure device can be opened to extract the soil inside the prestressed pipe pile 110 through the soil suction pipe. When the prestressed pipe pile 110 falls into the preset position, the buffer component 120 and the excavation pipe 140 are sequentially removed, and the earth-breaking component 130 is retained inside the foundation with the prestressed pipe pile 110.

[0024] As can be seen from the above, in the embodiment of the present application, by setting up the earth-breaking component 130, the second reserved groove 132 on the connecting platform 131 is used to connect with the prestressed pipe pile 110, and the earth-breaking cone 133 is used to separate the soil at the bottom of the prestressed pipe pile 110, so as to facilitate the pile placement, thereby accelerating the pile placement speed of the prestressed pipe pile 110. By setting up the soil suction port 134b, the excavation pipe 140 and the excavation hose 143, the excess soil in the prestressed pipe pile 110 can be sucked out, thereby reducing the resistance of the soil to the prestressed pipe pile 110, and further improving the efficiency of pile placement. In addition, by setting up the buffer component 120, the force of the pile driver acting on it can be evenly applied to the top of the prestressed pipe pile 110, thereby effectively avoiding the phenomenon of the pile driver directly acting on the prestressed pipe pile 110 causing damage to the prestressed pipe pile 110.

[0025] In some embodiments, an elastic buffer 122a is disposed inside the first reserved groove 122, and the other end of the elastic buffer 122a abuts against the top wall of the prestressed pipe pile 110. In the embodiment of the present application, the elastic buffer 122a can be in various forms such as a leather pad. Through the above arrangement, a buffer function can be achieved between the compression ring 121 and the prestressed pipe pile 110, further preventing the prestressed pipe pile 110 from being damaged.

[0026] In some embodiments, the second connecting member 142 includes a sleeve part 142a fixed to the bottom of the anti-pressure ring 121, a buffer spring 142b is arranged in the sleeve part 142a, and the top end of the excavation tube 140 extends to the inside of the sleeve part 142a and abuts against the bottom end of the buffer spring 142b. In the embodiment of the present application, when the anti-pressure ring 121 is hit by a pile driver, the relative position between the anti-pressure ring 121 and the prestressed pipe pile 110 may change. Therefore, in the present application, through the above-mentioned setting, the elongation and compression of the buffer spring 142b are used to make the connection between the excavation tube 140 and the anti-pressure ring 121 have a certain buffering effect, so that the excavation tube 140 will not be damaged.

[0027] In some embodiments, the first connecting member 141 includes a double-ended sleeve 141a, and both ends of the double-ended sleeve 141a are screwed to the bottom end of the excavation pipe 140 and the first threaded hole 134a. The embodiment of the present application shows a specific arrangement of the first connecting member 141, and the excavation pipe 140 and the connection box 134 can be conveniently connected as a whole through the double-ended sleeve 141a.

[0028] In some embodiments, a weak structure is provided in the middle of the double-headed sleeve 141a, and the weak structure includes a neck groove 141b provided in the middle of the double-headed sleeve 141a. In the embodiment of the present application, the neck groove 141b can be formed in the form of a chip brush sleeve. Since the cross-sectional thickness at the neck groove 141b is lower than the rest of the double-headed sleeve 141a, a weak structure will be formed here, which is more prone to damage than other positions. By making the above-mentioned arrangement, the present application can prevent the prestressed pipe pile 110 from falling to a suitable position, and then the buffer component 120 can be removed first, and then the unearthed pipe 140 can be held and shaken. At this time, the weak structure of the double-headed sleeve 141a will first break, and the unearthed pipe 140 can be easily taken out at this time, which is convenient for subsequent reuse. It should be noted that in the embodiment of the present application, the double-headed sleeve 141a is a disposable consumable, and each prestressed pipe pile 110 needs to be replaced during the pile dropping process.

[0029] In some embodiments, there are two earth-breaking parts 130, and the two earth-breaking parts 130 are symmetrically arranged on both sides of the bottom of the prestressed pipe pile 110. In the embodiment of the present application, through the above arrangement, on the one hand, the two earth-breaking parts 130 will support the prestressed pipe pile 110 more stably, and on the other hand, by setting two earth-breaking parts 130, correspondingly, the earth-excavation pipe 140 and the earth-excavation hose 143 can also be set to two, thereby increasing the efficiency of soil suction.

[0030] In some embodiments, a plurality of friction protrusions 132a are provided on the bottom wall of the second reserved groove 132. In the embodiment of the present application, the friction between the bottom end of the prestressed pipe pile 110 and the second reserved groove 132 can be increased through the above arrangement, thereby preventing the earth-breaking component 130 and the prestressed pipe pile 110 from slipping during the pile placement process.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application is described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should all be included in the scope of the claims and specification of the present application. In particular, as long as there is no structural conflict, the various technical features mentioned in the embodiments can be combined in any way. The present application is not limited to the specific embodiments disclosed herein, but includes all technical solutions that fall within the scope of the claims.
