Description

Technical Field

[0001] The present invention relates to the technical field of pile foundations, in particular to a green building reinforced concrete pile foundation structure. Background Art

[0002] Concrete piles are made of concrete (including conventional reinforced concrete and prestressed concrete). They offer advantages such as saving wood and steel, durability, and low cost. Concrete piles are widely used in hydraulic structures, industrial buildings, civil buildings, and bridge foundations. They are also commonly used in slope and foundation pit support for anti-slip or water-blocking purposes.

[0003] During the pile sinking process, you may encounter uneven foundation soil, such as differences in soil type, thickness, density, and mechanical properties in different areas. When encountering alternating layers of hard soil (such as gravel, boulders, and rock) and softer soil, the forces on both sides of the pile can easily become unbalanced during the sinking process, causing the pile to tilt. Once the pile tilt exceeds the permitted range (according to the "Technical Specifications for Building Pile Foundations," the vertical deviation of the pile is generally required to be no more than 1%), it will seriously affect the bearing capacity of the pile foundation, reduce the stability of the building, and delay the project progress. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a green building reinforced concrete pile foundation structure, comprising a concrete connecting plate, a main reinforcement cage fixedly connected to the outer wall of the concrete connecting plate, a pile body fixedly connected to the outer wall of the concrete connecting plate, and further comprising:

[0005] A protection mechanism, wherein the outer wall of the protection mechanism is fixedly connected to the outer wall of the pile body, and the protection mechanism is used to protect the pile body;

[0006] A stabilizing mechanism, wherein the outer wall of the stabilizing mechanism is fixedly connected to the outer wall of the protecting mechanism, and the stabilizing mechanism is used to stabilize the pile body;

[0007] An auxiliary mechanism, the inner wall of which is fixedly connected to the outer wall of the pile body, and the auxiliary mechanism is used to assist in pile connection;

[0008] The outer wall of the pile body is fixedly connected with a pile body front cap, the outer wall of the stabilizing mechanism is fixedly connected with a pile cap inner shell, and the outer wall of the pile cap inner shell is provided with a plurality of grooves.

[0009] Preferably, the protection mechanism includes:

[0010] A pile body assembly, wherein the outer wall of the pile body assembly is fixedly connected to the outer wall of the pile body;

[0011] A protective component, wherein the outer wall of the protective component is fixedly connected to the outer wall of the stabilizing mechanism.

[0012] Preferably, the stabilizing mechanism comprises:

[0013] A connecting assembly, wherein the outer wall of the connecting assembly is fixedly connected to the outer wall of the pile assembly;

[0014] The supporting assembly is rotatably connected to the outer wall of the connecting assembly at the outer wall of the supporting assembly.

[0015] Preferably, the auxiliary mechanism includes:

[0016] An auxiliary component, wherein the inner wall of the auxiliary component is fixedly connected to the outer wall of the pile body;

[0017] The pile connecting assembly has an outer wall that is slidably connected to the inner wall of the pile body.

[0018] Preferably, the pile assembly includes a plurality of fixed blocks fixedly connected to the outer wall of the hole, the outer walls of the plurality of fixed blocks are fixedly connected to connecting rods, and the inner walls of the connecting rods are rotatably connected to rotating shafts.

[0019] Preferably, the protection assembly includes a probe rod fixedly connected to the outer wall of the rotating shaft, the outer wall of the pile cap inner shell is fixedly connected to the pile cap outer shell, and the outer wall of the pile cap outer shell is provided with a plurality of holes;

[0020] The outer wall of the probe rod is slidably connected to the inner wall of the hole.

[0021] When in use, first place the protective mechanism at the front end of the pile body. At this time, use a hydraulic pile driver to sink the pile body using the static pressure method. When the pile body enters the soil layer, the outer wall of the pile cap shell will first contact the soft soil layer on the surface of the soil layer. As the pile is sunk, the pile cap shell will gradually penetrate into the soft soil layer. When the pile cap shell reaches the bearing layer in the soil layer, the pile cap shell will not be able to continue to sink under the action of the hydraulic press due to the hardness of the bearing layer soil. At this time, as the pressure of the hydraulic press on the pile body gradually increases, the strength of the pile cap inner shell will be unable to support it, causing the pile cap inner shell to tear open. Due to the presence of the groove, the crack will split along with the groove. When the groove cracks, its top has been in contact with the soil layer. The pile cap outer shell is connected, so that the cracked pile cap inner shell will rotate along the connection with the pile cap outer shell, which will drive the fixed block to rotate together, and then the probe rod will move accordingly. Due to the existence of the hole, the probe rod will move along the hole toward the soil layer. When the pile body reaches the set soil layer depth, the hydraulic machine will stop applying pressure to the pile body. However, the probe rod will continue to penetrate the soil layer with the movement of the pile body before reaching the soil layer depth. When the pile body stops moving, the probe rod will stop invading the soil layer and stay in the bearing layer. Therefore, when the pile sinking process stops, the presence of the probe rod will support the pile body, thereby reducing additional support for the pile body, improving construction efficiency, and saving construction time.

[0022] Preferably, the connection assembly includes two connection blocks 1 fixedly connected to the outer wall of the pile body front cap, two connection rods 1 rotatably connected to the outer walls of the two connection blocks 1, and two connection blocks 2 fixedly connected to the inner wall of the pile cap inner shell, and two connection rods 2 rotatably connected to the outer walls of the two connection blocks 2;

[0023] The inner wall of the two connecting rods 1 is rotatably connected to the outer wall of the two connecting rods.

[0024] When the pile is sunk, the pile will gradually move down, and the pile will not move due to any uneven force applied to it, which may cause the pile to tilt and fail to sink. When the front end of the pile encounters the local hard soil layer, the stabilizing mechanism will cause one side of the outer wall of the pile cap inner shell to first contact the hard soil layer, causing the pile cap inner shell to tilt toward the other side of the hard soil layer. At this time, the tilt of the pile cap inner shell will drive the connecting block 1 and the connecting block 2 to move closer to each other, thereby causing the connection between the connecting block 1 and the connecting rod 1 to move closer to the connection between the connecting block 2 and the connecting rod 2, causing the connection between the connecting rod 1 and the connecting rod 2 to move toward the bottom of the pile cap inner shell.

[0025] Preferably, the support assembly includes two push rods rotatably connected to the outer wall of the second connecting rod, the inner walls of the two push rods are rotatably connected to the first supporting rod, the inner wall of the first supporting rod is rotatably connected to the second supporting rod, the outer wall of the first supporting rod is slidably connected to the first resistance block, and the outer wall of the second supporting rod is slidably connected to the second resistance block;

[0026] The outer wall of the resistance block 1 is fixedly connected to the outer wall of the pile body front cap, and the outer wall of the resistance block 2 is fixedly connected to the inner wall of the pile cap inner shell.

[0027] The movement of the connection between the connecting rod 1 and the connecting rod 2 will cause the push rod to push the supporting rod 1 and the supporting rod 2 connected thereto to move together. Due to the existence of the resistance block 1 and the resistance block 2, the contact point between the supporting rod 1 and the resistance block 1 will be away from the contact point between the supporting rod 2 and the resistance block 2, thereby causing the front cap of the pile body and the inner shell of the pile cap to have a tendency to move away from each other, reducing the influence of the local hard soil layer on the pile body, causing the inclination angle of the pile body to have a tendency to decrease, thereby reducing the probability of pile sinking failure, improving construction efficiency, and saving construction time.

[0028] Preferably, the auxiliary component includes an auxiliary ring 1 fixedly connected to the outer wall of the pile body, an auxiliary ring 2 is rotatably connected to the outer wall of the auxiliary ring 1, a plurality of auxiliary connecting blocks are fixedly connected to the outer wall of the auxiliary ring 2, the plurality of auxiliary connecting blocks are grouped in pairs, a connecting shaft is rotatably connected to the inner walls of the two auxiliary connecting blocks, and an auxiliary plate is fixedly connected to the outer wall of the connecting shaft.

[0029] When the effective pile length is not enough for the construction requirement, it is necessary to connect the pile bodies that have been sunk. At this time, due to the heavy weight of the pile bodies, it is not easy to connect the two pile bodies when connecting them with the assistance of a machine. At this time, the bottom of the pile body of the connected pile will first contact the outer wall of the auxiliary plate. When the pile body of the connected pile continues to approach the pile head of the sunk pile, the auxiliary plate will rotate around the connection with the auxiliary connecting block. At this time, under the action of multiple auxiliary plates, the connected pile will be restricted inside the multiple auxiliary plates, thereby assisting the pile connection work, saving time for pile setting and improving construction efficiency.

[0030] Preferably, the pile connection assembly includes two connecting cavities opened on the inner wall of the pile body, the inner walls of the two connecting cavities are slidably connected with a pushing piston, the inner walls of the two connecting cavities are slidably connected with a blocking piston, and the inner wall of the pile body is slidably connected with a bolt.

[0031] When two pile bodies are connected, several bolts connected at the bottom of the connecting pile will be inserted into the holes reserved in the pile body. As the pile connection work proceeds, the bolts will gradually approach the pushing piston. When the bolts contact the pushing piston and make the pushing piston move toward the inside of the connecting cavity, since the inside of the connecting cavity is filled with hydraulic oil, the blocking piston will move toward the gap between the bolts. When the bolts reach the limit, the blocking piston will completely penetrate the gap between the bolts, thereby restricting the bolts inside the pile body, completing the pile connection work. No additional work is required on the two pile bodies, saving construction time and improving construction efficiency.

[0032] The present invention has the following beneficial effects:

[0033] (1) In order to solve the problem of the pile body tilting caused by the local hard soil layer in the soft soil layer during the pile sinking process, the present invention is provided with a stabilizing mechanism. When the front end of the pile body encounters the local hard soil layer, the outer wall of the pile cap inner shell will first contact the hard soil layer, thereby causing the pile cap inner shell to tilt toward the other side of the hard soil layer. At this time, the tilt of the pile cap inner shell will drive the connecting block 1 and the connecting block 2 to approach each other, and then cause the connection between the connecting block 1 and the connecting rod 1 to approach the connection between the connecting block 2 and the connecting rod 2, so that the connection between the connecting rod 1 and the connecting rod 2 is toward the pile cap inner shell. The bottom of the pile moves. At this time, the movement of the connection between the connecting rod 1 and the connecting rod 2 will cause the push rod to push the supporting rod 1 and the supporting rod 2 connected thereto to move together. Due to the existence of the resistance block 1 and the resistance block 2, the contact point between the supporting rod 1 and the resistance block 1 will be away from the contact point between the supporting rod 2 and the resistance block 2, thereby causing the front cap of the pile body and the inner shell of the pile cap to have a tendency to move away from each other, reducing the influence of the local hard soil layer on the pile body, making the inclination angle of the pile body tend to decrease, thereby reducing the probability of pile sinking failure, improving construction efficiency, and saving construction time;

[0034] (2) The present invention is to solve the problem that during construction, when the pile body enters the soft soil layer, it may encounter obstacles such as boulders, which will affect the strength of the pile body and thus reduce the construction efficiency. In addition, the pile body needs to be supported after the pile sinking is completed, which affects the construction efficiency. A protection mechanism is provided. When the pile cap shell reaches the bearing layer in the soil layer, the pile cap shell will not be able to continue to sink under the action of the hydraulic press due to the hardness of the bearing layer. At this time, as the pressure of the hydraulic press on the pile body gradually increases, the strength of the pile cap inner shell will be unable to support it, so that the pile cap inner shell will be torn apart. Due to the presence of the groove, the crack will split along with the groove. When the groove splits, its top is always connected to the pile cap shell. The probe rod is connected to the pile cap, so that the cracked pile cap inner shell will rotate along the connection with the pile cap outer shell, which will drive the fixed block to rotate together, and then the probe rod will move accordingly. Due to the existence of the hole, the probe rod will move along the hole toward the soil layer. When the pile body reaches the set soil layer depth, the hydraulic machine will stop applying pressure to the pile body. However, the probe rod will continue to penetrate the soil layer with the movement of the pile body before reaching the soil layer depth. When the pile body stops moving, the probe rod will stop invading the soil layer and stay in the bearing layer. Therefore, when the pile sinking process stops, the presence of the probe rod will support the pile body, thereby reducing additional support for the pile body, improving construction efficiency, and saving construction time.

[0035] (3) In order to solve the problem that it is not easy to connect two pile bodies with the assistance of a machine due to the heavy weight of the pile body when connecting the piles, the present invention is provided with an auxiliary component. The bottom of the pile body of the connected pile will first contact the outer wall of the auxiliary plate. When the pile body of the connected pile continues to approach the pile head of the pile, the auxiliary plate will rotate around the connection with the auxiliary connecting block. At this time, under the action of multiple auxiliary plates, the pile connection will be restricted to the interior of the multiple auxiliary plates, thereby assisting the pile connection work, saving the time of piling, and improving the construction efficiency.

[0036] (4) The present invention solves the problem that two pile bodies need to be connected when connecting piles. Since welding and other pile connection methods have complicated procedures and take a long time, a pile connection assembly is provided. Several bolts connected to the bottom of the pile are inserted into the holes reserved in the pile body. As the pile connection work proceeds, the bolts gradually approach the pushing piston. When the bolt contacts the pushing piston and causes the pushing piston to move toward the inside of the connecting chamber, since the inside of the connecting chamber is filled with hydraulic oil, the blocking piston will move toward the gap of the bolt. When the bolt reaches the limit, the blocking piston will completely invade the gap of the bolt, and then the bolt will be confined inside the pile body, completing the pile connection work. No additional work needs to be done on the two pile bodies, saving construction time and improving construction efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0052] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0053] For example 1, please refer to Figures 1-12 The present invention is a green building reinforced concrete pile foundation structure, comprising a concrete connecting plate 13, a main steel cage 14 fixedly connected to the outer wall of the concrete connecting plate 13, a pile body 15 fixedly connected to the outer wall of the concrete connecting plate 13, and further comprising:

[0054] The outer wall of the protection mechanism 1 is fixedly connected to the outer wall of the pile body 15, and the protection mechanism 1 is used to protect the pile body;

[0055] The stabilizing mechanism 2 is fixedly connected to the outer wall of the protecting mechanism 1 at its outer wall, and is used to stabilize the pile body;

[0056] Auxiliary mechanism 3, the inner wall of the auxiliary mechanism 3 is fixedly connected to the outer wall of the pile body 15, and the auxiliary mechanism 3 is used to assist in pile connection;

[0057] A pile body front cap 111 is fixedly connected to the outer wall of the pile body 15 , a pile cap inner shell 112 is fixedly connected to the outer wall of the stabilizing mechanism 2 , and a plurality of grooves 113 are formed on the outer wall of the pile cap inner shell 112 .

[0058] Protection agency 1 includes:

[0059] The pile body assembly 11, the outer wall of the pile body assembly 11 is fixedly connected to the outer wall of the pile body 15;

[0060] The protection component 12 has an outer wall fixedly connected to the outer wall of the stabilizing mechanism 2 .

[0061] The stabilizing mechanism 2 includes:

[0062] A connecting component 21, wherein the outer wall of the connecting component 21 is fixedly connected to the outer wall of the pile body component 11;

[0063] The supporting assembly 22 is rotatably connected to the outer wall of the connecting assembly 21 at its outer wall.

[0064] Auxiliary mechanism 3 includes:

[0065] An auxiliary component 31, the inner wall of the auxiliary component 31 is fixedly connected to the outer wall of the pile body 15;

[0066] The pile connecting assembly 32 has an outer wall that is slidably connected to the inner wall of the pile body 15 .

[0067] The pile assembly 11 includes a plurality of fixed blocks 114 fixedly connected to the outer wall of the hole 123 . A connecting rod 115 is fixedly connected to the outer wall of the plurality of fixed blocks 114 . A rotating shaft 116 is rotatably connected to the inner wall of the connecting rod 115 .

[0068] The protection assembly 12 includes a probe rod 121 fixedly connected to the outer wall of the rotating shaft 116, a pile cap outer shell 122 fixedly connected to the outer wall of the pile cap inner shell 112, and a plurality of holes 123 are formed on the outer wall of the pile cap outer shell 122;

[0069] The outer wall of the probe rod 121 is slidably connected to the inner wall of the hole 123 .

[0070] When in use, first place the protection mechanism 1 at the front end of the pile body 15. At this time, use a hydraulic pile driver to sink the pile body by static pressure. When the pile body enters the soil layer, the outer wall of the pile cap shell 122 will first contact the soft soil layer on the surface of the soil layer. As the pile is sunk, the pile cap shell 122 will gradually penetrate into the soft soil layer. When the pile cap shell 122 reaches the bearing layer in the soil layer, the pile cap shell 122 will not be able to continue to sink under the action of the hydraulic press due to the hardness of the bearing layer. At this time, as the pressure of the hydraulic press on the pile body gradually increases, the strength of the pile cap inner shell 112 will be unable to support it, so that the pile cap inner shell 112 will tear open. Due to the presence of the groove 113, the crack will split along with the groove 113. When the groove 113 splits, its top will always be in contact with the pile cap shell 122. When the pile body 15 stops moving, the probe rod 121 stops invading the soil layer and stays in the bearing layer. When the pile driving process stops, the existence of the probe rod 121 supports the pile body 15, thereby reducing the extra support for the pile body 15, improving the construction efficiency and saving the construction time.

[0071] For example 2, please refer to Figure 2-Figure 12 The present invention is a green building reinforced concrete pile foundation structure. Based on Example 1, the connection assembly 21 includes two connection blocks 211 fixedly connected to the outer wall of the pile body front cap 111, two connection rods 212 rotatably connected to the outer walls of the two connection blocks 211, two connection blocks 213 fixedly connected to the inner wall of the pile cap inner shell 112, and two connection rods 214 rotatably connected to the outer walls of the two connection blocks 213;

[0072] The inner wall of the two connecting rods 212 is rotatably connected to the outer wall of the two connecting rods 214.

[0073] During the pile sinking process, when the pile body 15 is sinking, due to the different soil conditions in the soft soil layer, a local hard soil layer may appear. When the front end of the pile body 15 encounters the existing local hard soil layer, the pile body 15 may tilt due to uneven force, thereby causing pile sinking failure. When the front end of the pile body 15 encounters the local hard soil layer, the stabilizing mechanism 2 will cause one side of the outer wall of the pile cap inner shell 112 to first contact the hard soil layer, thereby causing the pile cap inner shell 112 to tilt toward the other side of the hard soil layer. At this time, the tilt of the pile cap inner shell 112 will drive the connecting block 1 211 and the connecting block 2 213 to approach each other, thereby causing the connection between the connecting block 1 211 and the connecting rod 1 212 to approach the connection between the connecting block 2 213 and the connecting rod 2 214, so that the connection between the connecting rod 1 212 and the connecting rod 2 214 moves toward the bottom of the pile cap inner shell 112;

[0074] The support assembly 22 includes two push rods 221 rotatably connected to the outer wall of the second connecting rod 214, the inner walls of the two push rods 221 are rotatably connected to the first support rod 222, the inner wall of the first support rod 222 is rotatably connected to the second support rod 223, the outer wall of the first support rod 222 is slidably connected to the first resistance block 224, and the outer wall of the second support rod 223 is slidably connected to the second resistance block 225;

[0075] The outer wall of the resistance block 1 224 is fixedly connected to the outer wall of the pile body front cap 111 , and the outer wall of the resistance block 2 225 is fixedly connected to the inner wall of the pile cap inner shell 112 .

[0076] The movement of the connection between the first connecting rod 212 and the second connecting rod 214 will cause the push rod 221 to push the support rod 1 222 and the second support rod 223 connected thereto to move together. Due to the existence of the first resistance block 224 and the second resistance block 225, the contact point between the first supporting rod 222 and the first resistance block 224 will be away from the contact point between the second supporting rod 223 and the second resistance block 225, thereby causing the pile body front cap 111 and the pile cap inner shell 112 to have a tendency to move away from each other, reducing the influence of the local hard soil layer on the pile body 15, causing the inclination angle of the pile body 15 to have a tendency to decrease, thereby reducing the probability of pile sinking failure, improving construction efficiency, and saving construction time.

[0077] The auxiliary component 31 includes an auxiliary ring 1 311 fixedly connected to the outer wall of the pile body 15, an auxiliary ring 2 312 is rotatably connected to the outer wall of the auxiliary ring 1 311, a plurality of auxiliary connecting blocks 313 are fixedly connected to the outer wall of the auxiliary ring 2 312, and the plurality of auxiliary connecting blocks 313 are grouped in pairs. A connecting shaft 314 is rotatably connected to the inner walls of the two auxiliary connecting blocks 313, and an auxiliary plate 315 is fixedly connected to the outer wall of the connecting shaft 314.

[0078] When the effective pile length is not enough for the construction requirement, it is necessary to connect the pile bodies 15 that have been sunk. At this time, due to the heavy weight of the pile bodies 15, it is not easy to connect the two pile bodies 15 when connecting the two pile bodies 15 with the assistance of the machine. At this time, the bottom of the pile body 15 of the connected pile will first contact the outer wall of the auxiliary plate 315. When the pile body 15 of the connected pile continues to approach the pile head of the sunk pile, the auxiliary plate 315 will rotate around the connection with the auxiliary connecting block 313. At this time, under the action of the multiple auxiliary plates 315, the connected pile will be restricted to the inside of the multiple auxiliary plates 315, thereby assisting the pile connection work, saving the time of piling and improving the construction efficiency.

[0079] The pile connection assembly 32 includes two connecting cavities 321 opened on the inner wall of the pile body 15 , the inner walls of the two connecting cavities 321 are slidably connected to push pistons 322 , the inner walls of the two connecting cavities 321 are slidably connected to blocking pistons 323 , and the inner wall of the pile body 15 is slidably connected to bolts 324 .

[0080] When the two pile bodies are connected, the several bolts 324 connected at the bottom of the pile will be inserted into the holes reserved in the pile body 15. As the pile connection work proceeds, the bolts 324 will gradually approach the pushing piston 322. When the bolts 324 contact the pushing piston 322 and make the pushing piston 322 move toward the inside of the connecting chamber 321, since the inside of the connecting chamber 321 is filled with hydraulic oil, the blocking piston 323 will move toward the gap between the bolts 324. When the bolts 324 reach the limit, the blocking piston 323 will completely invade the gap between the bolts 324, thereby restricting the bolts 324 to the inside of the pile body 15, completing the pile connection work. No additional work is required on the two pile bodies, saving construction time and improving construction efficiency.

[0081] A specific application of this embodiment is: when in use, the protection mechanism 1 is first placed at the front end of the pile body 15. At this time, a hydraulic pile driver is used to sink the pile body by static pressure. When the pile body enters the soil layer, the outer wall of the pile cap shell 122 will first contact the soft soil layer on the surface of the soil layer. As the pile is sunk, the pile cap shell 122 will gradually penetrate into the soft soil layer. When the pile cap shell 122 reaches the bearing layer in the soil layer, the pile cap shell 122 will not be able to continue to sink under the action of the hydraulic press due to the hardness of the bearing layer. At this time, as the pressure of the hydraulic press on the pile body gradually increases, the strength of the pile cap inner shell 112 will be unable to support it, so that the pile cap inner shell 112 will tear open. Due to the presence of the groove 113, the crack will split along with the groove 113. When the groove 113 splits, its top will always be in contact with the soil layer. The pile cap outer shell 122 is connected, so that the cracked pile cap inner shell 112 will rotate along the connection with the pile cap outer shell 122, and at this time, the fixed block 114 will be driven to rotate together, and the probe rod 121 will also move accordingly. Due to the existence of the hole 123, the probe rod 121 will move along the hole 123 toward the soil layer. When the pile body 15 reaches the set soil layer depth, the hydraulic machine stops applying pressure to the pile body, and the probe rod 121 will continue to penetrate the soil layer with the movement of the pile body 15 before reaching the soil layer depth. When the pile body 15 stops moving, the probe rod 121 will stop invading the soil layer and stay in the bearing layer. Therefore, when the pile sinking process stops, the existence of the probe rod 121 will support the pile body 15, thereby reducing the additional support for the pile body 15, improving construction efficiency, and saving construction time.

[0082] During the pile sinking process, when the pile body 15 is sinking, due to the different soil conditions in the soft soil layer, a local hard soil layer may appear. When the front end of the pile body 15 encounters the existing local hard soil layer, the pile body 15 may tilt due to uneven force, thereby causing pile sinking failure. When the front end of the pile body 15 encounters the local hard soil layer, the stabilizing mechanism 2 will cause one side of the outer wall of the pile cap inner shell 112 to first contact the hard soil layer, thereby causing the pile cap inner shell 112 to tilt toward the other side of the hard soil layer. At this time, the tilt of the pile cap inner shell 112 will drive the connecting block 1 211 and the connecting block 2 213 to approach each other, thereby causing the connection between the connecting block 1 211 and the connecting rod 1 212 to approach the connection between the connecting block 2 213 and the connecting rod 2 214, so that The connection point between the first connecting rod 212 and the second connecting rod 214 moves toward the bottom of the pile cap inner shell 112. At this time, the movement of the connection point between the first connecting rod 212 and the second connecting rod 214 will cause the pushing rod 221 to push the supporting rod 1 222 and the second supporting rod 223 connected thereto to move together. Due to the existence of the resistance block 124 and the second resistance block 225, the contact point between the supporting rod 1 222 and the resistance block 1 224 will be away from the contact point between the supporting rod 2 223 and the resistance block 2 225, thereby causing the pile body front cap 111 and the pile cap inner shell 112 to have a tendency to move away from each other, reducing the influence of the local hard soil layer on the pile body 15, making the inclination angle of the pile body 15 tend to decrease, thereby reducing the probability of pile sinking failure, improving construction efficiency, and saving construction time;

[0083] When the effective pile length is not enough for the construction requirement, it is necessary to connect the pile bodies 15 that have been sunk. At this time, due to the heavy weight of the pile bodies 15, it is not easy to connect the two pile bodies 15 when connecting the two pile bodies 15 with the assistance of the machine. At this time, the bottom of the pile body 15 of the connected pile will first contact the outer wall of the auxiliary plate 315. When the pile body 15 of the connected pile continues to approach the pile head of the sunk pile, the auxiliary plate 315 will rotate around the connection with the auxiliary connecting block 313. At this time, under the action of the multiple auxiliary plates 315, the connected pile will be restricted to the inside of the multiple auxiliary plates 315, thereby assisting the pile connection work, saving the time of piling and improving the construction efficiency.

[0084] When the two pile bodies are connected, the several bolts 324 connected at the bottom of the pile will be inserted into the holes reserved in the pile body 15. As the pile connection work proceeds, the bolts 324 will gradually approach the pushing piston 322. When the bolts 324 contact the pushing piston 322 and make the pushing piston 322 move toward the inside of the connecting chamber 321, since the inside of the connecting chamber 321 is filled with hydraulic oil, the blocking piston 323 will move toward the gap between the bolts 324. When the bolts 324 reach the limit, the blocking piston 323 will completely invade the gap between the bolts 324, thereby restricting the bolts 324 to the inside of the pile body 15, completing the pile connection work. No additional work is required on the two pile bodies, saving construction time and improving construction efficiency.
