Description

Technical Field

[0001] This invention relates to the field of vibratory compaction construction technology, specifically to a 100-meter-class pile frame vibratory compaction device. Background Technology

[0002] In some special infrastructure scenarios, such as the construction of large hydropower stations, the leakage of water into the ground after the reservoir is filled will cause the overall foundation to soften. In addition, the dam needs to withstand the strong water pressure generated by the accumulated water. During the construction of the dam, due to the different depths of the overburden layer of different dams, the depth of the vibro-compacting piles in the foundation becomes deeper and deeper.

[0003] Currently, the conventional vibratory compaction equipment construction process typically involves a crane lifting a vibratory compactor with a guide rod, which then vibrates and compacts the ground to create a hole. This is followed by backfilling with stone and compaction to enhance the foundation's bearing capacity. However, after the crane lifts the guide rod, the crane boom is tilted relative to the ground, and the overall length of the boom is limited, making it impossible to suspend excessively long guide rods. Furthermore, current guide rods are usually one-piece structures with limited overall length. As the hole depth increases, the overall construction cost and difficulty rise sharply. Therefore, due to these factors, in actual engineering construction scenarios, conventional vibratory compaction equipment can generally only construct vibratory piles with depths below 35 meters, with the highest recorded depth being within 80 meters. There is currently no mature, stable, and reliable vibratory compaction equipment available for ultra-deep pile construction, especially for piles exceeding 100 meters in depth, which conventional vibratory compaction equipment is completely inadequate for.

[0004] In light of the above background, this application is hereby submitted. Summary of the Invention

[0005] The purpose of this application is to provide a 100-meter-class vibratory compaction equipment to solve the problem that conventional vibratory compaction equipment is difficult to use for 100-meter-class vibratory compaction piles.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following solution:

[0007] 100-meter-class vibratory compaction equipment for pile driving includes:

[0008] The multi-segment sleeve and vibratory impactor are provided. The multi-segment sleeve includes at least two coaxially sleeved sleeves. The vibratory impactor is connected to the bottom end of the sleeve with the smallest diameter. The sleeves in the sleeve with the largest diameter are provided with circumferential annular grooves at the ends away from the vibratory impactor. The sleeves also include detachable lifting rings with the same number of circumferential annular grooves.

[0009] The multi-segment sleeve includes a working sleeve and a non-working sleeve:

[0010] The working sleeve is a sleeve that restricts the axial approach to the vibratory compactor. The working sleeve is directly connected to the vibratory compactor or is connected by gravity through the detached lifting ring. The working sleeve and the vibratory compactor together form the vibratory compactor body.

[0011] The non-working sleeve is a sleeve that can approach the vibratory impactor along the axial direction. After the non-working sleeve is connected to the detached lifting ring by gravity, it becomes a working sleeve and is restricted from approaching the vibratory impactor.

[0012] The overall design concept of this application is to replace the conventional one-piece guide rod with a multi-segment sleeve. This multi-segment sleeve, together with the detachable lifting ring, forms a vibratory compaction body with an updatable length. This updatable vibratory compaction body enables multi-segment vibratory drilling, achieving ultra-deep vibratory compaction construction with depths exceeding 100 meters. Compared to conventional vibratory compaction equipment, the length of a single sleeve in the multi-segment sleeve can be similar to the length of the guide rod in conventional vibratory compaction equipment, thus avoiding manufacturing and transportation difficulties.

[0013] One of the originalities of this application lies in the gravity connection structure formed by the multi-segment sleeve and the detached lifting ring, and the resulting length-updable vibratory compaction body. Specifically, the detached lifting ring in this application only restricts the sleeve it supports through gravity; that is, it only restricts the sleeve's downward movement towards the vibratory compactor, not its upward movement. Therefore, throughout the vibratory compaction process, a certain degree of freedom can be maintained between the detached lifting ring and the sleeve it supports, preventing damage to the connection structure from the vibratory compaction action. Another unique feature of the vibratory compaction equipment in this application is that the total weight of the vibratory compaction body formed by the working sleeve and the vibratory compactor changes with the vibratory compaction depth range. The deeper the vibratory compactor is located, the longer the working sleeve, and the greater the total weight of the multi-segment vibratory compaction body formed by the working sleeve and the vibratory compactor. This effectively overcomes the different resistances caused by different formation depths during vibratory compaction, improving the efficiency and quality of vibratory compaction.

[0014] Preferred options also include:

[0015] The vertically installed support frame, and the guide structure and guide support structure that are slidably connected to the support frame vertically;

[0016] The guide structure is fixedly connected to the end of the sleeve with the largest diameter that is furthest from the vibratory impactor;

[0017] The guide support structure is used to support the sleeve in the non-working state or to guide the sleeve with the largest diameter. The guide support structure is set between the guide hanger structure and the vibratory impactor.

[0018] Preferably, it also includes a lifting assembly for pulling up the multi-segment sleeve, the lifting assembly including a first steel cable and a second steel cable respectively connected to the sleeve with the smallest diameter and the guide structure.

[0019] Preferably, the guide structure includes a guide assembly for guiding the sleeve with the largest diameter and at least one clamping assembly for gripping and supporting the sleeve in the non-working state, with the clamping assembly located below the guide assembly in the vertical direction.

[0020] Both the guide assembly and the clamping assembly include two openable C-shaped clamps. When the two C-shaped clamps are in the closed state, the guide assembly and the clamping assembly are coaxial.

[0021] The sleeves outside the smallest diameter sleeve are all provided with annular grooves or annular protrusions that are compatible with the clamping assembly at the end of the sleeve closest to the vibratory punch.

[0022] When there is more than one clamping component, two or more clamping components can simultaneously clamp and lift all non-working sleeves.

[0023] Preferably, both C-shaped clamps of the guide assembly and the clamping assembly are hydraulically driven;

[0024] The guide assembly consists of two C-shaped clamps forming an annular guide ring for guiding the sleeve with the largest diameter.

[0025] The two C-shaped clamps of the clamping assembly form an annular support ring for clamping and lifting the sleeve when it is not in operation. The annular support ring is adapted to the annular groove or annular protrusion.

[0026] Preferably, the multi-segment sleeve includes three coaxially sleeved sleeves, which are the sleeve with the smallest diameter, the second largest diameter, and the sleeve with the largest diameter, respectively. The number of the detachable lifting ring body is two, and the two detachable lifting ring bodies are respectively adapted to the circumferential ring grooves on the sleeve with the smallest diameter and the second largest diameter.

[0027] A separate lifting ring body adapted to the circumferential groove of the smallest diameter sleeve is used to support and limit the axial approach of the second diameter sleeve to the vibratory impactor.

[0028] The detachable lifting ring body, which is adapted to the circumferential groove of the second diameter sleeve, is used to support and limit the axial approach of the largest diameter sleeve to the vibratory impactor.

[0029] Preferably, the multi-segment sleeve consists of two coaxially fitted sleeves, which are the sleeve with the smallest diameter and the sleeve with the largest diameter, respectively. The number of the detachable lifting ring body is one, and the detachable lifting ring body is adapted to the circumferential annular groove on the sleeve with the smallest diameter.

[0030] A separate lifting ring body, adapted to the circumferential groove of the smallest diameter sleeve, is used to support and restrict the largest diameter sleeve from approaching the vibratory impactor axially.

[0031] Preferably, the length of a single sleeve in the multi-segment sleeve ranges from 17 meters to 30 meters.

[0032] Preferably, the inner and outer diameters of the working sleeve with the largest diameter are defined as A1 and A2, respectively, and the diameter of its circumferential groove is defined as A3.

[0033] The inner and outer diameters of the sleeve with the smallest diameter in the non-working state are defined as B1 and B2, respectively;

[0034] The inner and outer diameters of the lifting ring are defined as D1 and D2, respectively.

[0035] The working sleeve with the largest diameter, the non-working sleeve with the smallest diameter, the inner and outer diameters of the lifting ring body, and the diameter of the circumferential annular groove satisfy the following mathematical relationship:

[0036] Relationship 1: A1 < A3 = D1 < A2 < B1 < D2;

[0037] Relationship 2: A1 < A3 = D1 < A2 < B1 < B2.

[0038] Preferably, the detachable lifting ring body includes at least two C-shaped sleeves, and the two or more C-shaped sleeves can be detachably connected and assembled into an annular detachable lifting ring body adapted to the circumferential annular groove.

[0039] The beneficial effects of this invention are:

[0040] This application, by setting up multiple sleeves and a detachable lifting ring, enables the multiple sleeves to switch between working and non-working states through the disassembly and assembly of the detachable lifting ring, thereby forming a vibratory compaction body with updatable length, realizing multi-segment vibratory compaction construction, achieving ultra-deep vibratory compaction construction with a depth of up to 100 meters, and solving the problem of ultra-deep vibratory compaction construction with a depth of over 100 meters.

[0041] The device of this application, in the vibratory compaction and filling stages at different depth ranges, with its multi-segment sleeve working state, detached lifting ring body, and vibratory compactor forming a vibratory compaction body by gravity, can provide different weights for the compaction and filling at different depth ranges, thereby overcoming the different resistances caused by the formation at different depth ranges during the vibratory compaction and filling process, and improving the quality and efficiency of the compaction.

Detailed Implementation

[0062] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0063] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "longitudinal," "lateral," "horizontal," "inner," "outer," "front," "rear," "top," and "bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use.

Therefore, they should not be construed as limitations on this invention.

[0064] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "have," "install," "connect," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0065] The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0066] Example 1:

[0067] like Figures 1 to 12 As shown, this embodiment provides a 100-meter-level vibratory compaction device for pile frames, including:

[0068] The multi-sleeve 1 and the vibratory impactor 2 are provided. The multi-sleeve 1 includes at least two coaxially sleeved sleeves. The vibratory impactor 2 is connected to the bottom end of the sleeve with the smallest diameter 11. The sleeves in the sleeve with the largest diameter 13 are provided with circumferential annular grooves 111 at the ends away from the vibratory impactor 2. The multi-sleeve 1 also includes detachable lifting rings 7 with the same number of circumferential annular grooves 111.

[0069] The multi-segment sleeve 1 includes a working sleeve and a non-working sleeve:

[0070] The working sleeve is a sleeve that restricts the axial approach to the vibratory impactor 2. The working sleeve is directly connected to the vibratory impactor 2 or connected by gravity through the detached lifting ring 7. The working sleeve and the vibratory impactor 2 form a vibratory impactor body.

[0071] The non-working sleeve is a sleeve that can approach the vibratory impactor 2 along the axial direction. After the non-working sleeve is connected to the detached lifting ring 7 by gravity, it becomes a working sleeve and is restricted from approaching the vibratory impactor 2.

[0072] The overall design concept of this application is to replace the conventional one-piece guide rod with a multi-segment sleeve 1. This multi-segment sleeve 1, together with the detachable lifting ring 7, forms a length-upgradable vibratory compaction body. This length-upgradable vibratory compaction body enables multi-segment vibratory drilling, thereby achieving ultra-deep vibratory compaction construction with depths exceeding 100 meters. Compared to conventional vibratory compaction equipment, the length of a single sleeve in the multi-segment sleeve 1 can be similar to the length of the guide rod in conventional vibratory compaction equipment, thus avoiding manufacturing and transportation difficulties.

[0073] One of the originalities of this application lies in the gravity connection structure formed by the multi-segment sleeve 1 and the detached lifting ring 7, and the vibration impact body whose length can be updated through this gravity connection structure. In particular, the detached lifting ring 7 in this application restricts the sleeve supported on it only through gravity. (Refer to...) Figure 5 As shown, after the detachable lifting ring 7 is installed into the circumferential annular groove 111, the sleeve above it can be limited. Under the action of gravity, the sleeve above it can be connected to the detachable lifting ring 7. That is, the detachable lifting ring 7 only restricts the sleeve supported by it from moving downwards towards the vibratory compactor 2, but does not restrict the sleeve supported by it from moving upwards. Therefore, during the entire vibratory compaction process, the detachable lifting ring 7 and the sleeve supported by it can be guaranteed to have a certain degree of freedom, which can avoid damage to the connection structure caused by the vibratory compaction action. In addition, another unique feature of the vibratory compaction equipment of this application is that the total weight of the vibratory compaction body formed by the working sleeve and the vibratory compactor 2 changes with the position of the vibratory compaction depth range. The deeper the depth range in which the vibratory compactor 2 is located, the longer the length of the working sleeve, and the greater the total weight of the multi-segment vibratory compaction body formed by the working sleeve and the vibratory compactor 2. This can effectively overcome the different resistance caused by different formation depths during vibratory compaction, and can improve the efficiency and quality of vibratory compaction.

[0074] In a preferred example embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, it also includes:

[0075] The vertically arranged support frame 6, and the guide structure 4 and guide support structure 5 that are slidably connected to the support frame 6 along the vertical direction;

[0076] The guide structure 4 is fixedly connected to the end of the sleeve 13 with the largest diameter that is furthest from the vibratory impactor 2;

[0077] The guide support structure 5 is used to support the sleeve in the non-working state or to guide the sleeve 13 with the largest diameter. The guide support structure 5 is set between the guide hanging structure 4 and the vibratory impactor 2.

[0078] In this embodiment, when both the secondary diameter sleeve 12 and the largest diameter sleeve 13 are in a non-working state, after the guide structure 5 locks the secondary diameter sleeve 12, since the top of the smallest diameter sleeve 11 is located inside the secondary diameter sleeve 12, the guide structure 5 can also simultaneously limit the smallest diameter sleeve 11, thus guiding it. When the secondary diameter sleeve 12 is connected to the smallest diameter sleeve 11 by gravity through the detachable lifting ring 7, the secondary diameter sleeve 12 becomes a working sleeve. At this time, the guide structure 5 holds and lifts the largest diameter sleeve. Sleeve 13, and since the top of the secondary diameter sleeve 12 is located inside the largest diameter sleeve 13, the guide support structure 5 can not only hold and lift the largest diameter sleeve 13, but also limit the secondary diameter sleeve 12, thereby achieving the guiding effect on the vibratory impact body. When the largest diameter sleeve 13 is connected to the secondary diameter sleeve 12 through the detachable lifting ring 7, the largest diameter sleeve 13 becomes a working sleeve. At this time, by using the guide support structure 5 and the guide hanging structure 4 to guide the largest diameter sleeve 13 at the same time, the vibratory impact body can be guided, avoiding deviation during the entire vibratory impact process.

[0079] In a preferred example embodiment, such as Figure 1As shown, it also includes a lifting assembly 3 for pulling up the multi-segment sleeve 1. The lifting assembly 3 includes a first steel cable 31 and a second steel cable 32 connected to the sleeve with the smallest diameter 11 and the guide structure 5, respectively. In this embodiment, two first steel cables 31 are provided. In some embodiments, three or more first steel cables 31 can be provided, and the three or more first steel cables 31 are evenly distributed along the circumference of the vibratory impactor 2. In this embodiment, the first steel cables 31 can lift up the sleeve with the smallest diameter 11 and the vibratory impactor 2. The working sleeves outside the sleeve with the smallest diameter 11 are all connected by gravity through the detached lifting ring 7. Therefore, by fixing the first steel cable 31 to the working sleeve with the smallest diameter, all the working sleeves and the detached lifting ring 7 can be lifted. Under the action of gravity, the working sleeves and the detached lifting ring 7 can form a whole vibratory impactor body for vibratory impact. In this embodiment, the second steel cable 32 can lift the guide support structure 5. After the guide support structure 5 holds and lifts the non-working sleeve, the second steel cable 32 can pull up the guide support structure 5, thereby making the non-working sleeve held and lifted on the guide support structure 5 in a suspended state. This prevents the non-working sleeve from falling down under the action of gravity during the vibration of the vibrating body and during the disassembly and assembly of the lifting ring body 7.

[0080] In a preferred example embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the guide support structure 5 includes a guide assembly 51 for guiding the sleeve 13 with the largest diameter and at least one clamping assembly 52 for clamping and supporting the sleeve in the non-working state. The clamping assembly 52 is located below the guide assembly 51 in the vertical direction.

[0081] Both the guide assembly 51 and the clamping assembly 52 include two openable C-shaped clamps 53. When the two C-shaped clamps 53 are in the closed state, the guide assembly 51 and the clamping assembly 52 are coaxial.

[0082] The sleeves outside the smallest diameter sleeve 11 are all provided with annular grooves or annular protrusions that are compatible with the clamping assembly 52 at the end of the sleeves near the vibratory impactor 2.

[0083] When there is more than one clamping component, two or more clamping components can simultaneously clamp and lift all non-working sleeves. In this embodiment, the annular structure adapted to the clamping component 52 is an annular groove (not shown in the figure). In some embodiments, it can also be an annular protrusion.

[0084] It is understood that in this embodiment, by setting up a guide support structure 5 and a guide hanging structure 4, and the guide support structure 5 is provided with two clamping components 52, when the secondary diameter sleeve 12 and the maximum diameter sleeve 13 are in a non-working state, the two clamping components 52 of the guide support structure 5 can be used to clamp the secondary diameter sleeve 12 and the maximum diameter sleeve 13 simultaneously, so as to prevent the vibratory impact body from falling during the vibratory impact process and during the disassembly and assembly of the detachment lifting ring 7. At the same time, when the secondary diameter sleeve 12 is connected to the minimum diameter sleeve 11 by the force of the detachment lifting ring 7, the clamping component 52 that clamps the secondary diameter sleeve 12 is released first. When the maximum diameter sleeve 13 is connected to the secondary diameter sleeve 12 by the force of the other detachment lifting ring 7, the clamping component 52 that clamps the maximum diameter sleeve 13 is released again. Then, the guide component 51 of the guide support structure 5 is used for guidance. In this embodiment, the clamping component 52 clamps all non-working sleeves at the same time, and then releases the clamping component 52 in sequence according to the actual connection situation. This can avoid the guide structure 5 moving up and down repeatedly to clamp, and can effectively improve the connection efficiency and disassembly efficiency of the detached lifting ring 7.

[0085] In a preferred example embodiment, such as Figure 2 and Figure 3 As shown, both C-shaped clamps 53 of the guide assembly 51 and the clamping assembly 52 are hydraulically driven;

[0086] The two C-shaped clamps 53 of the guide assembly 51 form an annular guide ring for guiding the sleeve 13 with the largest diameter;

[0087] The two C-shaped clamps 53 of the clamping assembly 52 form an annular support ring for clamping and supporting the sleeve in the non-working state. The annular support ring is adapted to an annular groove or annular protrusion. In this embodiment, the C-shaped clamps 53 are semi-circular clamping structures. The inner wall shape of the two C-shaped clamps 53 of the guide assembly 51 is adapted to the annular groove or annular protrusion of the sleeve with the largest diameter. The annular support ring formed by the two C-shaped clamps 53 of the clamping assembly 52 is adapted to the outer wall shape of the sleeve in the non-working state.

[0088] When there is more than one clamping component 52, the clamping component 52 with the highest position is adapted to the annular groove or annular protrusion of the sleeve with the largest diameter 13, and the clamping components 52 with the successively lower positions are adapted to the annular groove or annular protrusion of the sleeve inside the sleeve with the largest diameter 13.

[0089] In this embodiment, the multi-segment sleeve 1 includes three coaxially sleeved sleeves, namely the sleeve with the smallest diameter 11, the sleeve with the second largest diameter 12 and the sleeve with the largest diameter 13. The number of the detached lifting ring body 7 is 2, and the 2 detached lifting ring bodies 7 are respectively adapted to the circumferential ring grooves 111 on the sleeve with the smallest diameter 11 and the sleeve with the second largest diameter 12.

[0090] A separate lifting ring 7, adapted to the circumferential groove 111 of the smallest diameter sleeve 11, is used to support and restrict the secondary diameter sleeve 12 from approaching the vibratory impactor 2 axially.

[0091] The detachable lifting ring 7, which is adapted to the circumferential groove 111 of the secondary diameter sleeve 12, is used to support and restrict the axial approach of the largest diameter sleeve 13 to the vibratory impactor 2.

[0092] In a preferred embodiment, the length of a single sleeve of the multi-sleeve 1 ranges from 17 meters to 30 meters. In this embodiment, the length of a single sleeve can be 17 meters, 20 meters, 25 meters, 30 meters, or other heights.

[0093] In a preferred embodiment, a sealing structure 14 is further provided between the smallest diameter sleeve 11 and the second largest diameter sleeve 12, and between the second largest diameter sleeve 12 and the largest diameter sleeve 13. The sealing structure 14 can prevent mud from entering the sleeve.

[0094] In this embodiment, the inner diameter and outer diameter of the working sleeve with the largest diameter are defined as A1 and A2, respectively, and the diameter of its circumferential groove 111 is defined as A3.

[0095] The inner and outer diameters of the sleeve with the smallest diameter in the non-working state are defined as B1 and B2, respectively;

[0096] The inner and outer diameters of the lifting ring are defined as D1 and D2, respectively.

[0097] The working sleeve with the largest diameter, the non-working sleeve with the smallest diameter, the inner and outer diameters of the lifting ring body, and the diameter of the circumferential annular groove 111 satisfy the following mathematical relationship:

[0098] Relationship 1: A1 < A3 = D1 < A2 < B1 < D2;

[0099] Relationship 2: A1 < A3 = D1 < A2 < B1 < B2.

[0100] In this embodiment, refer to Figure 5 and Figure 6 As shown, D2 is less than B2. In some embodiments, D2 may also be equal to B2, and in some embodiments, D2 may also be greater than B2.

[0101] In a preferred embodiment, the detachable lifting ring 7 includes at least two C-shaped sleeves 73, which are detachably connected and can be assembled into an annular detachable lifting ring 7 that fits the circumferential annular groove 111. In this embodiment, as... Figure 6As shown, the C-shaped sleeve 73 is a semi-circular sleeve. Both ends of the C-shaped sleeve 73 are provided with end through holes 731 that are perpendicular to its end face. Two C-shaped sleeves 73 can be assembled into a circular three-dimensional lifting ring by connecting and fixing them with bolts and nuts.

[0102] like Figure 13 As shown, when using the vibratory compaction equipment of this embodiment for pile making, the entire process includes: a multi-stage vibratory compaction hole-making process and a multi-stage vibratory compaction pile-making process. The multi-stage vibratory compaction hole-making process specifically includes:

[0103] S1, Primary Hole Formation: The working sleeve and the vibratory punch 2 form a vibratory punch body, which is used to perform vibratory punching to create holes. The working sleeve is the smallest diameter sleeve 11, and the largest diameter sleeve 13 and the second largest diameter sleeve 12 are non-working sleeves.

[0104] S2, First connection: When the circumferential groove 111 of the smallest diameter sleeve 11 is exposed from the second diameter sleeve 12, the detached lifting ring 7 is inserted into the circumferential groove 111, and the second diameter sleeve 12 is released to the side of the detached lifting ring 7 away from the ground. The released second diameter sleeve 12 is connected to the smallest diameter sleeve by gravity through the detached lifting ring 7 and becomes a new working state sleeve. The smallest diameter sleeve 11, the second diameter sleeve 12 and the vibratory impactor 2 form a new vibratory impactor.

[0105] S3, Secondary Hole Formation: Using the new vibratory punch in S2, a second hole formation is performed based on the first hole formation;

[0106] S4, Secondary Connection: When the circumferential groove 111 of the secondary diameter sleeve 12 is exposed, another detachable lifting ring 7 is inserted into the circumferential groove 111, and the largest diameter sleeve 13 is released to the side of the detachable lifting ring 7 away from the ground. The released largest diameter sleeve 13 is connected to the secondary diameter sleeve 12 by gravity through the detachable lifting ring 7 and becomes a new working sleeve. The three sleeves and the vibratory impactor 2 form a new vibratory impactor.

[0107] S5, Third-stage hole making: Using the new vibratory punch in S4, a third-stage hole making is performed based on the second-stage hole making;

[0108] like Figures 1 to 9 As shown, during the first drilling, the depth of the vibratory drilling is within a certain area, forming a first-section vibratory hole. During the second drilling, the depth of the vibratory drilling is within a second-section area. After the drilling is completed, a vibratory hole consisting of one section and two sections is formed. During the third drilling, the depth of the vibratory drilling is within a third-section area. After the drilling is completed, a vibratory hole consisting of one section, two sections, and three sections is formed. The depth of a vibratory hole consisting of one section, two sections, and three sections can reach hundreds of meters.

[0109] The multi-stage vibratory compaction pile-making process specifically includes:

[0110] S6, 1st filling: Fill the vibratory hole created by the vibratory punching body with filler material, and then use the vibratory punching body to vibrate and punch in the vibratory hole. The sleeve with the largest diameter 13, the second largest diameter sleeve 12 and the sleeve with the smallest diameter 11 are all working sleeves.

[0111] S7, 1st disassembly: When the detached lifting ring 7, which is stuck on the secondary diameter sleeve 12, rises to the preset height, the largest diameter sleeve 13 is lifted or lifted, and the detached lifting ring 7 is disassembled from the circumferential ring groove 111. The largest diameter sleeve 13 is transformed into a suspended non-working sleeve, and the original working sleeve is transformed into the smallest diameter sleeve 11 and the secondary diameter sleeve 12. The smallest diameter sleeve 11, the secondary diameter sleeve 12, and the vibratory impactor 2 form a new vibratory impactor.

[0112] S8, Secondary packing: Using the new vibratory impactor in S7, secondary packing is carried out on the basis of primary packing.

[0113] S9, 2nd disassembly: When the detached lifting ring 7, which is stuck on the smallest diameter sleeve 11, rises to the preset height, the second diameter sleeve 12 is lifted or lifted up, and the detached lifting ring 7 is disassembled from the circumferential annular groove 111. The second diameter sleeve 12 is transformed into a suspended non-working sleeve, and the original working sleeve is transformed into the smallest diameter sleeve 11. The smallest diameter sleeve 11 and the vibratory impactor 2 form a new vibratory impactor.

[0114] S10, 3rd packing, utilizes the new vibratory impactor in S9 to perform 3rd packing on the basis of 2nd packing.

[0115] In some preferred embodiments, the vibratory compactor includes a flushing port on the vibratory compactor 2; the multi-segment vibratory compaction hole-making process also includes a hole-cleaning process with the same number of iterations as the hole-making process, with each hole-cleaning process following the hole-making process. The hole-cleaning process following the hole-making process avoids the repeated connection and disassembly of the multi-segment sleeve 1, compared to the conventional method of cleaning the hole after the entire hole-making process is completed.

[0116] In this embodiment, as Figure 13 As shown, the hole cleaning process is as follows:

[0117] S11: First cleaning of the hole, using the flushing port on the vibratory punch 2 to repeatedly flush a section of vibratory punch hole created in the hole-making process;

[0118] S31: Second cleaning of the hole, using the flushing port on the vibratory punch 2 to repeatedly flush the first and second vibratory punch holes made in the hole making process;

[0119] S51: Three-stage hole cleaning: The first, second, and third-stage vibratory holes created in the hole-making process are repeatedly flushed using the flushing nozzle on the vibratory punch 2.

[0120] Example 2:

[0121] like Figures 14 to 18 As shown, in this embodiment, the multi-sleeve sleeve consists of 12 coaxially sleeved sleeves, two of which are the sleeve with the smallest diameter 11 and the sleeve with the largest diameter 13. The number of the detachable lifting ring 7 is 1, and the detachable lifting ring 7 is adapted to the circumferential annular groove 111 on the sleeve with the smallest diameter 11.

[0122] The detachable lifting ring 7, which is adapted to the circumferential groove 111 of the smallest diameter sleeve 11, is used to support and restrict the largest diameter sleeve 13 from approaching the vibratory impactor 2 axially.

[0123] In this embodiment, the guide support structure 5 includes a guide assembly 51 for guiding the sleeve 13 with the largest diameter and a clamping assembly 52 for clamping and supporting the sleeve in the non-working state. The clamping assembly 52 is located below the guide assembly 51 in the vertical direction.

[0124] Both the guide assembly 51 and the clamping assembly 52 include two openable C-shaped clamps 53. When the two C-shaped clamps 53 are in the closed state, the guide assembly 51 and the clamping assembly 52 are coaxial.

[0125] The sleeves outside the smallest diameter sleeve 11 are all provided with annular grooves or annular protrusions that are adapted to the clamping assembly 52 at the end near the vibratory impactor 2. When the smallest diameter sleeve 11 and the vibratory impactor 2 move downwards, or when the detachable lifting ring 7 is disassembled or assembled, the clamping assembly 52 is used to hold or lift the largest diameter sleeve 13 to prevent the largest diameter sleeve 13 from falling. In some embodiments, the guide structure 4 is also used to hang the largest diameter sleeve 13. After the largest diameter sleeve 13 is connected to the detachable lifting ring 7 by gravity, the guide assembly 51 of the guide structure 4 and the guide support structure 5 is used to guide the largest diameter sleeve 13 to prevent the vibratory impactor from deviating during the vibratory impact process.

[0126] The remaining structures in this embodiment are the same as those in Embodiment 1 above, and will not be described again here.

[0127] When using the vibratory compaction equipment of this embodiment for pile making, the process flow diagram of vibratory compaction pile making is as follows: Figure 18 As shown, when using the vibratory compaction equipment of this embodiment for pile making, the entire process includes: a multi-stage vibratory compaction hole-making process and a multi-stage vibratory compaction pile-making process. The multi-stage vibratory compaction hole-making process specifically includes:

[0128] S1, 1st hole making: The working sleeve and the vibratory punch 2 form a vibratory punch body, and the vibratory punch body is used to make holes by vibratory punching. The working sleeve is the sleeve with the smallest diameter 11, and the sleeve with the largest diameter 13 is the sleeve in the non-working state.

[0129] S2, First connection: When the circumferential groove 111 on the smallest diameter sleeve 11 is exposed from the largest diameter sleeve 13, the detached lifting ring body 7 is inserted into the circumferential groove 111, and the largest diameter sleeve 13 is released to the side of the detached lifting ring body 7 away from the ground. The released largest diameter sleeve 13 is connected to the smallest diameter sleeve 11 by gravity through the detached lifting ring body 7 and becomes a new working state sleeve. The largest diameter sleeve 13, the smallest diameter sleeve 11 and the vibratory impactor 2 form a new vibratory impactor body.

[0130] S3, Secondary Hole Formation: Using the new vibratory punch in S2, a second hole formation is performed based on the first hole formation;

[0131] The multi-stage vibratory compaction pile-making process specifically includes:

[0132] S6, 1st filling: Fill the vibratory hole created by the vibratory punching body with filler material, and then use the vibratory punching body to vibrate and punch in the vibratory hole. The sleeve with the largest diameter 13 and the sleeve with the smallest diameter 11 are both working sleeves.

[0133] S7, 1st disassembly: When the detached lifting ring 7, which is stuck on the smallest diameter sleeve 11, rises to the preset height, the largest diameter sleeve 13 is lifted or lifted, and the detached lifting ring 7 is disassembled from the circumferential annular groove 111. The largest diameter sleeve 13 is transformed into a suspended non-working sleeve, and the original working sleeve is transformed into the smallest diameter sleeve 11. The smallest diameter sleeve 11 and the vibratory impactor 2 form a new vibratory impactor.

[0134] S8, secondary packing, utilizes the new vibratory impactor in S7 to perform secondary packing based on primary packing.

[0135] In some preferred embodiments, the vibratory compactor includes a flushing port on the vibratory compactor 2; the multi-segment vibratory compaction hole-making process also includes a hole-cleaning process with the same number of iterations as the hole-making process, with each hole-cleaning process following the hole-making process. The hole-cleaning process following the hole-making process avoids the repeated connection and disassembly of the multi-segment sleeve 1, compared to the conventional method of cleaning the hole after the entire hole-making process is completed.

[0136] In this embodiment, as Figure 18 As shown, it also includes two hole cleaning processes following the hole-making process. The hole cleaning process is as follows:

[0137] S11: First cleaning of the hole, using the flushing port on the vibratory punch 2 to repeatedly flush a section of vibratory punch hole created in the hole-making process;

[0138] S31: Second cleaning of the hole, using the flushing port on the vibratory punch 2 to repeatedly flush the first and second vibratory punch holes created in the hole-making process.

[0139] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, and the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
