Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pile foundation, in particular to a green building reinforced concrete pile foundation structure. BACKGROUND

[0002] Concrete pile refers to the pile made of concrete (including ordinary reinforced concrete, prestressed concrete). It has the advantages of saving wood and steel, durability, low cost, etc. Concrete piles have been widely used in water conservancy construction, industrial construction, civil construction and bridge foundation engineering, and are often used in slope and foundation pit support anti-skid or water isolation engineering.

[0003] During the process of sinking the pile, unevenness of the foundation soil may be encountered, such as differences in the type, thickness, compactness and mechanical properties of the soil layer in different areas. When hard soil layers (such as sand and gravel layers, boulders, rock layers) and soft soil layers are alternately distributed, the stress on both sides of the pile body during the sinking process is easily unbalanced, resulting in tilting of the pile body. Once the pile body tilting exceeds the allowable range (according to the "Building Pile Foundation Technical Specification", the verticality deviation of the pile body is usually required to be not more than 1%), the bearing capacity of the pile foundation will be seriously affected, the stability of the building will be reduced, and the progress of the project will be delayed. SUMMARY

[0005] A protection mechanism fixedly connected to the outer wall of the pile body, the protection mechanism being used for protecting the pile body;

[0006] A stabilizing mechanism fixedly connected to the outer wall of the protection mechanism, the stabilizing mechanism being used for stabilizing the pile body;

[0007] An auxiliary mechanism fixedly connected to the outer wall of the pile body, the auxiliary mechanism being used for assisting in pile connection;

[0008] A pile body front cap fixedly connected to the outer wall of the pile body, a pile cap inner shell fixedly connected to the outer wall of the stabilizing mechanism, and a plurality of grooves formed in the outer wall of the pile cap inner shell.

[0009] Preferably, the protection mechanism comprises:

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

[0011] A protection assembly fixedly connected to the outer wall of the stabilizing mechanism.

[0012] Preferably, the stabilizing mechanism comprises:

[0013] The connecting assembly is fixedly connected with the outer wall of the pile body assembly at the outer wall thereof;

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

[0015] Preferably, the auxiliary mechanism comprises:

[0016] The auxiliary assembly is fixedly connected with the outer wall of the pile body at the inner wall thereof;

[0017] The pile connecting assembly is slidably connected with the inner wall of the pile body at the outer wall thereof.

[0018] Preferably, the pile body assembly comprises a plurality of fixing blocks fixedly connected with the outer wall of the hole, a connecting rod fixedly connected with the outer wall of the fixing blocks, and a rotating shaft rotatably connected with the inner wall of the connecting rod.

[0019] Preferably, the protection assembly comprises a probe rod fixedly connected with the outer wall of the rotating shaft, a pile cap outer shell fixedly connected with the outer wall of the pile cap inner shell, and a plurality of holes formed in the outer wall of the pile cap outer shell.

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

[0021] In use, first, the protection mechanism is placed at the front end of the pile body, at this time, the pile body is subjected to static pressure pile sinking by using a hydraulic pile driver, when the pile body enters the soil layer, the outer wall of the pile cap outer shell will first contact the soft soil layer on the surface of the soil layer, as the pile sinking proceeds, the pile cap outer shell will gradually penetrate into the soft soil layer, when the pile cap outer shell reaches the bearing layer in the soil layer, the pile cap outer shell will not be able to continue to sink under the action of the hydraulic machine due to the hardness of the bearing layer soil, at this time, as the pressure of the hydraulic machine on the pile body gradually increases, the strength of the pile cap inner shell will not be able to support, so that the pile cap inner shell will tear open, due to the existence of the groove, the crack will tear along the groove, when the groove tears open, the torn pile cap inner shell will rotate along the connection with the pile cap outer shell due to the fact that the top end thereof is always connected with the pile cap outer shell, at this time, the fixing block will also rotate, and thus the probe rod will also move, due to the existence of the hole, the probe rod will move along the hole towards the soil layer, when the pile body reaches the set soil depth, the hydraulic machine will stop pressing the pile body, and the probe rod will stop penetrating into the soil layer and stay in the bearing layer due to the fact that the probe rod will always penetrate into the soil layer along with the movement of the pile body before the soil depth is reached, so that when the pile sinking process stops, the existence of the probe rod will support the pile body, so as to reduce the additional support for the pile body, improve the construction efficiency, and save the construction time.

[0022] Preferably, the connecting assembly comprises two connecting blocks I fixedly connected to the outer wall of the pile cap, two connecting rods I rotatably connected to the outer wall of the two connecting blocks I, two connecting blocks II fixedly connected to the inner wall of the pile cap inner shell, and two connecting rods II rotatably connected to the outer wall of the two connecting blocks II.

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

[0024] During the pile sinking process, when the pile body sinks, due to different soil conditions in the soft soil layer, a local hard soil layer may be formed. When the front end of the pile body encounters the existing local hard soil layer, uneven stress may cause the pile body to tilt, resulting in pile sinking failure. The stabilizing mechanism is arranged to cause the outer wall of the pile cap inner shell to first contact the hard soil layer when the front end of the pile body encounters the local hard soil layer, thereby causing the pile cap inner shell to tilt towards the other side of the hard soil layer. At this time, the tilt of the pile cap inner shell causes the connecting blocks I and II to move closer to each other, thereby causing the connecting portion of the connecting rod I to move closer to the connecting portion of the connecting rod II, and causing the connecting portion of the connecting rod I to move towards the bottom of the pile cap inner shell.

[0025] Preferably, the supporting assembly comprises two pushing rods rotatably connected to the outer wall of the connecting rod II, a supporting rod I rotatably connected to the inner wall of the two pushing rods, a supporting rod II rotatably connected to the inner wall of the supporting rod I, a resistance block I slidably connected to the outer wall of the supporting rod I, and a resistance block II slidably connected to the outer wall of the supporting rod II.

[0026] The outer wall of the resistance block I is fixedly connected to the outer wall of the pile cap, and the outer wall of the resistance block II is fixedly connected to the inner wall of the pile cap inner shell.

[0027] The movement of the connecting portion of the connecting rod I and the connecting rod II causes the pushing rod to move together with the supporting rod I and the supporting rod II. Due to the presence of the resistance block I and the resistance block II, the contact portion of the supporting rod I and the resistance block I moves away from the contact portion of the supporting rod II and the resistance block II, thereby causing the pile cap and the pile cap inner shell to move away from each other. This reduces the impact of the local hard soil layer on the pile body and reduces the angle of inclination of the pile body, thereby reducing the probability of pile sinking failure, improving construction efficiency, and saving construction time.

[0028] Preferably, the auxiliary assembly comprises an auxiliary ring I fixedly connected to the outer wall of the pile body, an auxiliary ring II rotatably connected to the outer wall of the auxiliary ring I, a plurality of auxiliary connecting blocks fixedly connected to the outer wall of the auxiliary ring II, the plurality of auxiliary connecting blocks being paired into a group, a connecting shaft rotatably connected to the inner wall of the two auxiliary connecting blocks, and an auxiliary plate fixedly connected to the outer wall of the connecting shaft.

[0029] When the effective pile length is not enough for the construction requirements, the pile body of the sunk pile needs to be spliced, at this time, due to the large weight of the pile body, it is not easy to splice the two pile bodies with the aid of the machine, at this time, the bottom of the spliced pile body will first contact the outer wall of the auxiliary plate, when the spliced pile body 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 splicing will be limited inside the multiple auxiliary plates, thereby assisting the splicing work, saving the time of the pile and improving the construction efficiency;

[0030] Preferably, the pile splicing assembly comprises two connecting cavities opened at the inner wall of the pile body, the inner wall of the two connecting cavities is slidably connected with a pushing piston, the inner wall of the two connecting cavities is slidably connected with a blocking piston, and the inner wall of the pile body is slidably connected with a bolt.

[0031] When the two pile bodies are connected, the several bolts connected at the bottom of the spliced pile body will be inserted into the reserved hole in the pile body, as the splicing work proceeds, the bolt will gradually approach the pushing piston, when the bolt contacts the pushing piston and makes the pushing piston move towards the inside of the connecting cavity, since the connecting cavity is filled with hydraulic oil, the blocking piston will move towards the gap of the bolt, when the bolt reaches the limit, the blocking piston will completely invade the gap of the bolt, thereby the bolt is limited inside the pile body, the splicing work is completed, no additional work is needed for the two pile bodies, the construction time is saved, and the construction efficiency is improved;

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

[0033] (1) The present application is used for solving the pile body inclination caused by the local hard soil layer in the soft soil layer during the pile sinking process, the stabilizing mechanism is provided, when the front end of the pile body meets 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 incline to the other side of the hard soil layer, at this time, the inclination of the pile cap inner shell will drive the connection block one and the connection block two to move close to each other, thereby causing the connection between the connection rod one and the connection block one to move close to the connection between the connection block two and the connection rod two, and the connection between the connection rod one and the connection rod two moves towards the bottom of the pile cap inner shell, at this time, the movement of the connection between the connection rod one and the connection rod two will cause the pushing rod to push the support rod one and the support rod two to move together, and due to the existence of the resistance block one and the resistance block two, the contact between the support rod one and the resistance block one will move away from the contact between the support rod two and the resistance block two, thereby the pile body cap and the pile cap inner shell have a mutual moving away trend, the influence of the local hard soil layer on the pile body is reduced, the inclination angle of the pile body has a reducing trend, thereby the probability of pile sinking failure is reduced, the construction efficiency is improved, and the construction time is saved;

[0034] (2) The present application is to solve the problem that the pile body may encounter obstacles such as boulders when it enters the soft soil layer during construction, which affects the strength of the pile body and reduces the construction efficiency. In addition, the pile body needs to be supported after the pile sinking is completed, which affects the construction efficiency. The protection mechanism is provided. When the pile cap shell reaches the bearing layer in the soil layer, the pile cap shell cannot continue to sink under the action of the hydraulic machine due to the hardness of the bearing layer soil. At this time, as the pressure of the hydraulic machine on the pile body gradually increases, the strength of the pile cap inner shell cannot be supported, causing the pile cap inner shell to tear open. Due to the existence of the groove, the crack will tear along the groove. When the groove is torn, the torn pile cap inner shell will rotate along the connection with the pile cap shell. At this time, the fixed block will also rotate, and the probe rod will also move. Due to the existence of the hole, the probe rod will move along the hole towards the soil layer. When the pile body reaches the set soil layer depth, the hydraulic machine will stop pressing the pile body. Before the soil layer depth is reached, the probe rod will always penetrate into the soil layer along with the movement of the pile body. When the pile body stops moving, the probe rod will stop penetrating into the soil layer and stay in the bearing layer. Therefore, when the pile sinking process stops, the existence of the probe rod will support the pile body, thereby reducing the additional support for the pile body and improving the construction efficiency and saving the construction time.

[0035] (3) The present application is to solve the problem that the weight of the pile body is too large when connecting the piles, and it is not easy to connect the two pile bodies with the help of the machine. The auxiliary assembly is provided. The bottom of the pile to be connected will first contact the outer wall of the auxiliary plate. When the pile to be connected continues to approach the pile head of the pile to be sunk, 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 to be connected will be limited inside the multiple auxiliary plates, thereby assisting the pile connection work, saving the time for connecting the piles and improving the construction efficiency.

[0036] (4) The present application is to solve the problem that two pile bodies need to be connected when connecting the piles, and the welding method for connecting the piles is complicated and time-consuming. The pile connecting assembly is provided. The plurality of bolts connected at the bottom of the pile to be connected will be inserted into the hole reserved in the pile body. As the pile connecting work proceeds, the bolt will gradually approach the push piston. When the bolt contacts the push piston and makes the push piston move towards the inside of the connecting cavity, the hydraulic oil filled in the connecting cavity will make the blocking piston move towards the gap of the bolt. When the bolt reaches the limit, the blocking piston will completely invade the gap of the bolt, thereby limiting the bolt inside the pile body and completing the pile connecting work. No additional work is needed for the two pile bodies, saving the construction time and improving the construction efficiency. BRIEF DESCRIPTION OF DRAWINGS

[0068] The protection assembly 12 comprises a probe rod 121 fixedly connected with the outer wall of the rotating shaft 116, a pile cap outer shell 122 fixedly connected with the outer wall of the pile cap inner shell 112, and a plurality of holes 123 formed in the outer wall of the pile cap outer shell 122.

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

[0070] In use, first, the protection mechanism 1 is placed at the front end of the pile body 15, at this time, the pile body is subjected to static pressure method pile sinking by using the hydraulic pile driver, when the pile body enters the soil layer, the outer wall of the pile cap outer shell 122 will first contact the soft soil layer on the surface of the soil layer, with the pile sinking, the pile cap outer shell 122 will gradually penetrate into the soft soil layer, when the pile cap outer shell 122 reaches the bearing layer in the soil layer, the pile cap outer shell 122 will not be able to continue to sink under the action of the hydraulic machine due to the hardness of the bearing layer soil layer, at this time, with the gradual increase of the pressure of the hydraulic machine on the pile body, the strength of the pile cap inner shell 112 cannot be supported, so that the pile cap inner shell 112 will tear open, due to the existence of the groove 113, the crack will tear along the groove 113, when the groove 113 is torn, due to the fact that the top end is always connected with the pile cap outer shell 122, the torn pile cap inner shell 112 will rotate along the connection with the pile cap outer shell 122, at this time, the fixed block 114 will also rotate, and then the probe rod 121 will also move, due to the existence of the hole 123, the probe rod 121 will move along the hole 123 towards the soil layer, when the pile body 15 reaches the set soil layer depth, the hydraulic machine will stop pressing the pile body, and the probe rod 121 will stop penetrating into the soil layer and stay in the bearing layer before the soil layer depth is reached, when the pile body 15 stops moving, the probe rod 121 will stop penetrating into the soil layer and stay in the bearing layer, so that 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 the construction efficiency and saving the construction time.

[0071] In example two, please refer to Figures 2-12 The green building reinforced concrete pile foundation structure comprises a pile body, a pile cap outer shell, a pile cap inner shell, a fixed block, a probe rod and a hole.

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

[0073] When the pile body 15 encounters a local hard soil layer during sinking, the pile body 15 may be inclined due to uneven force, and the pile sinking fails. When the pile body 15 encounters a local hard soil layer, the outer wall of the pile cap inner shell 112 is first in contact with the hard soil layer, so that the pile cap inner shell 112 is inclined to the other side of the hard soil layer. At this time, the inclination of the pile cap inner shell 112 drives the connecting block one 211 and the connecting block two 213 to move closer to each other, so that the connecting part of the connecting rod one 212 and the connecting rod two 214 moves towards the bottom of the pile cap inner shell 112.

[0074] The support assembly 22 comprises two push rods 221 rotatably connected to the outer wall of the connecting rod two 214, the inner wall of the two push rods 221 is rotatably connected with a support rod one 222, the inner wall of the support rod one 222 is rotatably connected with a support rod two 223, the outer wall of the support rod one 222 is slidably connected with a resistance block one 224, and the outer wall of the support rod two 223 is slidably connected with a resistance block two 225.

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

[0076] The movement of the connecting part of the connecting rod one 212 and the connecting rod two 214 drives the push rod 221 to move together with the support rod one 222 and the support rod two 223. Due to the existence of the resistance block one 224 and the resistance block two 225, the contact part of the support rod one 222 and the resistance block one 224 is away from the contact part of the support rod two 223 and the resistance block two 225, so that the pile body front cap 111 and the pile cap inner shell 112 have a tendency to move away from each other, reducing the influence of the local hard soil layer on the pile body 15, reducing the inclination angle of the pile body 15, and reducing the probability of pile sinking failure, improving the construction efficiency and saving the construction time.

[0077] The auxiliary assembly 31 comprises an auxiliary ring one 311 fixedly connected to the outer wall of the pile body 15, an auxiliary ring two 312 rotatably connected to the outer wall of the auxiliary ring one 311, a plurality of auxiliary connecting blocks 313 fixedly connected to the outer wall of the auxiliary ring two 312, the plurality of auxiliary connecting blocks 313 are two by two, the inner wall of the two auxiliary connecting blocks 313 is rotatably connected with a connecting shaft 314, and the outer wall of the connecting shaft 314 is fixedly connected with an auxiliary plate 315.

[0078] When the effective pile length is not enough for the construction requirements, the pile body 15 of the sunk pile needs to be spliced. At this time, due to the large weight of the pile body 15, it is not easy to splice the two pile bodies 15 with the assistance of the machine. At this time, the bottom of the spliced pile body 15 will first contact the outer wall of the auxiliary plate 315. When the spliced pile body 15 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 multiple auxiliary plates 315, the splicing will be limited inside the multiple auxiliary plates 315, thereby assisting the splicing work, saving the time of the pile, and improving the construction efficiency;

[0079] The splicing assembly 32 includes two connecting cavities 321 opened at the inner wall of the pile body 15. The inner wall of the two connecting cavities 321 is slidably connected with a pushing piston 322, and the inner wall of the two connecting cavities 321 is slidably connected with a blocking piston 323. The inner wall of the pile body 15 is slidably connected with a bolt 324.

[0080] When the two pile bodies are connected, the several bolts 324 connected at the bottom of the splicing pile will be inserted into the reserved hole in the pile body 15. As the splicing work proceeds, the bolt 324 will gradually approach the pushing piston 322. When the bolt 324 contacts the pushing piston 322 and makes the pushing piston 322 move towards the inside of the connecting cavity 321, since the connecting cavity 321 is filled with hydraulic oil, the blocking piston 323 will move towards the gap of the bolt 324. When the bolt 324 reaches the limit, the blocking piston 323 will completely invade the gap of the bolt 324, thereby making the bolt 324 be limited inside the pile body 15, completing the splicing work, without the need for additional work on the two pile bodies, saving construction time and improving construction efficiency;

[0081] One specific application of the embodiment is: in use, first place the protection mechanism 1 at the front end of the pile body 15, at this time, use the hydraulic pile driver to carry out static pressure method pile sinking, 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, with the progress of pile sinking, 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 machine due to the hardness of the bearing layer soil, at this time, with the gradual increase of the pressure of the hydraulic machine on the pile body, the strength of the pile cap inner shell 112 will not be able to support, so that the pile cap inner shell 112 will tear open, due to the existence of the groove 113, the crack will tear along the groove 113, when the groove 113 is torn, due to its top end is always connected with the pile cap shell 122, so that the torn pile cap inner shell 112 will rotate along the connection with the pile cap shell 122, at this time it will drive the fixed block 114 to rotate, so that the probe rod 121 will also move, due to the existence of the hole 123, it will cause the probe rod 121 to move along the hole 123 towards the soil layer, when the pile body 15 reaches the set soil depth, the hydraulic machine will stop pressing the pile body, while the probe rod 121 will always penetrate into the soil layer with the movement of the pile body 15 before reaching the soil depth, when the pile body 15 stops moving, the probe rod 121 will stop invading the soil layer and stay in the bearing layer, so that when the pile sinking process stops, the existence of the probe rod 121 will support the pile body 15, so as to reduce the additional support for the pile body 15, improve the construction efficiency and save the construction time;

[0082] When the pile body 15 encounters a local hard soil layer during sinking, the pile body 15 may be inclined due to uneven stress, and the pile sinking may fail. When the pile body 15 encounters a local hard soil layer, the outer wall of the pile cap inner shell 112 on one side is first in contact with the hard soil layer, so that the pile cap inner shell 112 is inclined to the other side of the hard soil layer. At this time, the inclination of the pile cap inner shell 112 causes the connecting block one 211 and the connecting block two 213 to move closer to each other, and the connecting block one 211 and the connecting rod one 212 are connected to the connecting block two 213 and the connecting rod two 214, so that the connecting rod one 212 and the connecting rod two 214 are connected to the bottom of the pile cap inner shell 112. At this time, the movement of the connecting rod one 212 and the connecting rod two 214 causes the pushing rod 221 to push the support rod one 222 and the support rod two 223 to move together. Due to the presence of the resistance block one 224 and the resistance block two 225, the contact between the support rod one 222 and the resistance block one 224 is away from the contact between the support rod two 223 and the resistance block two 225, so that the pile body front cap 111 and the pile cap inner shell 112 are inclined to each other, reducing the influence of the local hard soil layer on the pile body 15, and reducing the inclination angle of the pile body 15, thereby reducing the probability of pile sinking failure, improving the construction efficiency, and saving the construction time.

[0083] When the effective pile length is not enough for construction requirements, the pile body 15 needs to be connected to the pile. At this time, due to the large weight of the pile body 15, it is not easy to connect the two pile bodies 15 with the help of the machine. At this time, the bottom of the pile body 15 will first contact the outer wall of the auxiliary plate 315. When the pile body 15 continues to approach the pile head, the auxiliary plate 315 will rotate around the connection with the auxiliary connecting block 313. At this time, under the action of multiple auxiliary plates 315, the pile connection is limited inside the multiple auxiliary plates 315, so as to assist the pile connection work, save the pile time, and improve the construction efficiency.

[0084] When the two piles are connected, the several bolts 324 connected at the pile bottom of the pile spliced pile are inserted into the reserved hole of the pile body 15, and as the pile splicing work is carried out, the bolts 324 gradually approach the pushing piston 322, when the bolts 324 contact the pushing piston 322 and make the pushing piston 322 move towards the inside of the connecting cavity 321, because the connecting cavity 321 is filled with hydraulic oil, the blocking piston 323 moves towards the gap of the bolt 324, when the bolt 324 reaches the limit, the blocking piston 323 completely invades the gap of the bolt 324, so that the bolt 324 is limited in the inside of the pile body 15, the pile splicing work is completed, and additional work is not needed for the two piles, construction time is saved, and construction efficiency is improved;
