Description

Technical Field

[0001] This invention relates to the field of vibro-compaction construction technology, specifically to the construction process of 100-meter-class vibro-compaction piles. Background Technology

[0002] In some special infrastructure scenarios, such as the construction of large hydropower stations, the seepage 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. As the depth of the overburden layer varies from dam to dam, the vibro-compacted piles are made deeper and deeper during the dam construction process.

[0003] Conventional construction techniques typically involve using a crane to suspend a guide rod and a vibratory compactor. The vibratory compactor then creates the borehole, followed by filling and compaction processes to complete the pile driving. However, after the crane lifts the guide rod, its boom is tilted relative to the ground, limiting its overall length and making it unsuitable for suspending excessively long guide rods. Furthermore, current guide rods are usually one-piece structures with limited overall length. As the borehole depth increases, the overall construction cost and difficulty rise dramatically. Therefore, due to these factors, in actual engineering projects, the construction depth of conventional vibratory compaction piles is usually below 35 meters, with the highest recorded depth being less than 80 meters. There is currently no mature construction technology for ultra-deep vibratory compaction piles, especially for depths exceeding 100 meters; this area remains largely unexplored, and conventional construction techniques are completely inadequate.

[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 construction process for a 100-meter-class vibratory compaction pile, thereby solving the construction process problems of 100-meter-class vibratory compaction piles.

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

[0007] The construction process of 100-meter-class pile frame type vibratory compaction pile includes: multi-sleeve and vibratory compactor. The multi-sleeve includes at least two coaxially sleeved sleeves. The vibratory compactor is set at the bottom end of the sleeve with the smallest diameter. The sleeve in the sleeve with the largest diameter is provided with a circumferential groove at the end away from the vibratory compactor. It also includes a number of detachable lifting rings that are the same as the number of circumferential grooves.

[0008] The multi-segment sleeve includes a working sleeve inserted into the ground and a non-working sleeve suspended in the air. The working sleeve and the vibratory compactor together form a vibratory compactor body.

[0009] The construction process includes a multi-stage vibratory compaction hole-making process;

[0010] The multi-stage vibratory punching hole-making process includes M hole-making processes and N connection processes, where M is greater than or equal to 2 and N is greater than or equal to 1.

[0011] The hole-making process is as follows: using a vibratory punch to create holes;

[0012] The connection process is as follows: when the circumferential groove on the working sleeve of the vibratory impactor is exposed from the non-working sleeve, the detachable lifting ring body is inserted into the exposed circumferential groove, and the non-working sleeve with the smallest diameter is released to the side of the detachable lifting ring body away from the ground. The released non-working sleeve is connected to the working sleeve by the weight of the detachable lifting ring body and becomes a new working sleeve. The new working sleeve, the original working sleeve, and the vibratory impactor form a new vibratory impactor.

[0013] 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 compaction drilling, achieving ultra-deep vibratory compaction construction with depths exceeding 100 meters. Compared to conventional construction processes, the length of a single sleeve in the multi-segment sleeve can be similar to the length of the guide rod in conventional processes, thus avoiding manufacturing and transportation difficulties. In this embodiment, the drilling and connection processes are performed alternately. In this construction process, the height of the pile driver frame should be approximately 2 to 3 meters greater than the length of a single sleeve.

[0014] One of the originalities of this application lies in the gravity connection structure formed by the multi-segment sleeve and the detached lifting ring, which forms a vibratory compaction body with an updatable length. Based on this updatable vibratory compaction body, a multi-segment vibratory compaction construction process is implemented to form ultra-deep vibratory compaction holes with a depth of up to 100 meters. Another unique feature of this vibratory compaction construction process is that the total weight of the vibratory compaction body composed of the sleeve and vibratory compactor in the working state changes with the position of the vibratory compaction depth range. The deeper the vibratory compactor is in the depth range, the greater the total weight of the vibratory compaction body composed of the sleeve and vibratory compactor in the working state. This can effectively overcome the different resistance caused by different strata depths during vibratory compaction, and can improve the efficiency and quality of vibratory compaction.

[0015] Preferably, the multi-stage vibratory punching hole-making process further includes M hole-cleaning processes, which are the same number of times as the hole-making process, with each hole-cleaning process following the hole-making process;

[0016] The vibratory body includes a flushing port provided on the vibratory compactor;

[0017] The hole cleaning process involves repeatedly rinsing the vibratory holes created in the hole-making process using the flushing nozzle on the vibratory punch.

[0018] Preferably, when M is 2, N is 1, and there are 2 sleeves, the two sleeves are the sleeve with the largest diameter and the sleeve with the smallest diameter, respectively. The multi-stage vibratory punching hole-making process is as follows:

[0019] S1, First-time hole making: The working sleeve and the vibratory punch form a vibratory punch body, which is used to make holes by vibratory punching. The working sleeve is the sleeve with the smallest diameter, and the sleeve with the largest diameter is the sleeve in the non-working state.

[0020] S2, 1st connection: When the circumferential groove on the smallest diameter sleeve is exposed from the largest diameter sleeve, the detached lifting ring body is inserted into the circumferential groove, and the largest diameter sleeve is released to the side of the detached lifting ring body away from the ground. The released largest diameter sleeve is connected to the smallest diameter sleeve by the weight of the detached lifting ring body and becomes a new working state sleeve. The largest diameter sleeve, the smallest diameter sleeve and the vibratory impactor form a new vibratory impactor body.

[0021] S3, Secondary Hole Formation: Using the new vibratory punch in S2, a secondary hole formation is performed based on the first hole formation.

[0022] Preferably, when M is 3, N is 2, and there are 3 sleeves, the 3 sleeves are the sleeve with the largest diameter, the sleeve with the second largest diameter, and the sleeve with the smallest diameter. The multi-stage vibratory punching hole-making process is as follows:

[0023] S1, Primary Hole Formation: The working sleeve and vibratory punch form a vibratory punching body, which is used to perform vibratory punching hole formation. The working sleeve is the sleeve with the smallest diameter, while the sleeve with the largest diameter and the second largest diameter sleeve are the sleeves in the non-working state.

[0024] S2, First connection: When the circumferential groove of the smallest diameter sleeve is exposed from the second diameter sleeve, the detached lifting ring body is inserted into the circumferential groove, and the second diameter sleeve is released to the side of the detached lifting ring body away from the ground. The released second diameter sleeve is connected to the smallest diameter sleeve by the weight of the detached lifting ring body and becomes a new working state sleeve. The smallest diameter sleeve, the second diameter sleeve and the vibratory impactor form a new vibratory impactor body.

[0025] S3, Secondary Hole Formation: Using the new vibratory punch in S2, a second hole formation is performed based on the first hole formation;

[0026] S4, Secondary Connection: When the circumferential groove of the secondary diameter sleeve is exposed, another detachable lifting ring body is inserted into the circumferential groove, and the largest diameter sleeve is released to the side of the detachable lifting ring body away from the ground. The released largest diameter sleeve is connected to the secondary diameter sleeve by the weight of the detachable lifting ring body and becomes a new working state sleeve. The three sleeves and the vibratory impactor form a new vibratory impactor body.

[0027] 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.

[0028] Preferably, it also includes a multi-stage vibratory compaction pile-making process:

[0029] The multi-stage vibratory compaction pile manufacturing process includes M filling processes and N disassembly processes, where M is greater than or equal to 2 and N is greater than or equal to 1.

[0030] Filling process: Fill the vibratory holes created by the vibratory punching body with filler material, and then use the vibratory punching body to vibrate and punch in the vibratory holes.

[0031] Disassembly process: When the detached lifting ring body, which is attached to the working sleeve of the vibratory impactor, rises to the preset height, the working sleeve with the largest diameter is lifted or lifted, and the detached lifting ring body is disassembled from the circumferential groove. The working sleeve with the largest diameter is transformed into a suspended non-working sleeve, and the original working sleeve is transformed into a new working sleeve. The new working sleeve and the vibratory impactor form a new vibratory impactor.

[0032] Preferably, when M is 2 and N is 1, the two sleeves are the sleeve with the largest diameter and the sleeve with the smallest diameter, and the multi-stage vibratory compaction pile-making process is as follows:

[0033] 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 and the sleeve with the smallest diameter are both working sleeves.

[0034] S7, 1st disassembly: When the detached lifting ring body, which is stuck on the smallest diameter sleeve, rises to the preset height, the largest diameter sleeve is lifted or lifted, and the detached lifting ring body is disassembled from the circumferential ring groove. The largest diameter sleeve becomes a suspended non-working sleeve, and the original working sleeve becomes the smallest diameter sleeve. The smallest diameter sleeve and the vibratory impactor form a new vibratory impactor.

[0035] S8, secondary packing, utilizes the new vibratory impactor in S7 to perform secondary packing based on primary packing.

[0036] Preferably, when M is 3 and N is 2, the three sleeves are the sleeve with the largest diameter, the sleeve with the second largest diameter, and the sleeve with the smallest diameter, respectively. The multi-segment vibratory compaction pile-making process is as follows:

[0037] 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, the second largest diameter sleeve and the sleeve with the smallest diameter are all working sleeves.

[0038] S7, 1st disassembly: When the detached lifting ring body clamped on the secondary diameter sleeve rises to the preset height, the largest diameter sleeve is lifted or lifted, and the detached lifting ring body is disassembled from the circumferential ring groove. The largest diameter sleeve is transformed into a suspended non-working state sleeve, and the original working state sleeve is transformed into the smallest diameter sleeve and the secondary diameter sleeve. The smallest diameter sleeve, the secondary diameter sleeve and the vibratory punch form a new vibratory punch body.

[0039] S8, Secondary packing: Using the new vibratory impactor in S7, secondary packing is carried out on the basis of primary packing.

[0040] S9, 2nd disassembly: When the detached lifting ring body clamped on the smallest diameter sleeve rises to the preset height, the second diameter sleeve is lifted or lifted, and the detached lifting ring body is disassembled from the circumferential groove. The second diameter sleeve is transformed into a suspended non-working sleeve, and the original working sleeve is transformed into the smallest diameter sleeve. The smallest diameter sleeve and the vibratory impactor form a new vibratory impactor.

[0041] S10, 3rd packing, utilizes the new vibratory impactor in S9 to perform 3rd packing on the basis of 2nd packing.

[0042] Preferably, in the multi-segment vibratory drilling process and the multi-segment vibratory pile making process, it is necessary to use steel cables to lift the working sleeve with the smallest diameter. In the case of non-working sleeves, it is also necessary to use a guide support structure to support or / and a guide hanging structure to hang the non-working sleeves.

[0043] In the hole-making process of the multi-segment vibratory compaction hole-making process and the filling process of the multi-segment vibratory compaction pile-making process, in the absence of a non-working sleeve, it is also necessary to use a guide support structure or / and a guide hanger structure to guide the working sleeve with the largest diameter.

[0044] Preferably, in the multi-segment vibratory compaction drilling process and the multi-segment vibratory compaction pile making process, the depth of each drilling segment and the depth of each filling segment range from 17 meters to 30 meters.

[0045] Preferably, in the multi-stage vibratory punching hole-making process, before the initial hole-making process, all non-working sleeves need to be lifted up using a guide support structure, and the non-working sleeves with the smallest diameter are released sequentially in the subsequent connection process.

[0046] In the dismantling process of multi-stage vibratory compaction pile making, while the guide support structure holds all the non-working sleeves tightly, the guide support structure is used to lift the working sleeve with the largest diameter, thus transforming the working sleeve with the largest diameter into the non-working sleeve with the smallest diameter.

[0047] 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.

[0048] The inner and outer diameters of the sleeve with the smallest diameter in the non-working state are defined as B1 and B2, respectively;

[0049] The inner and outer diameters of the lifting ring are defined as D1 and D2, respectively.

[0050] 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:

[0051] Relationship 1: A1 < A3 = D1 < A2 < B1 < D2;

[0052] Relationship 2: A1 < A3 = D1 < A2 < B1 < B2.

[0053] The beneficial effects of this invention are:

[0054] This application, by setting up multiple sleeves, enables the multiple sleeves to switch between working and non-working states, thereby forming a vibratory compaction body with an 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.

[0055] This application utilizes the multi-segment sleeve working state, the detached lifting ring body, and the vibratory compactor to form a vibratory compactor body under gravity during the vibratory compaction and filling stages at different depths in the construction process. This allows for different weights to be provided for the drilling and vibratory compaction at different depths, thereby overcoming the different resistances caused by the strata at different depths during the drilling and filling process and improving the quality and efficiency of drilling.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0075] The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0076] Example 1:

[0077] like Figures 1 to 7 As shown, this embodiment provides a construction process for a 100-meter-level vibratory compaction pile. The 100-meter-level vibratory compaction pile includes: a multi-sleeve 1 and a vibratory compactor 2. The multi-sleeve 1 includes at least two coaxially sleeved sleeves. The vibratory compactor 2 is located at 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 grooves 111 at the ends away from the vibratory compactor 2. It also includes detachable lifting rings 7 in the same number as the circumferential grooves 111.

[0078] The multi-segment sleeve 1 includes a working sleeve inserted into the ground and a non-working sleeve suspended in the air. The working sleeve and the vibratory compactor 2 form a vibratory compactor body.

[0079] The construction process includes a multi-stage vibratory compaction hole-making process;

[0080] The multi-stage vibratory punching hole-making process includes M hole-making processes and N connection processes, where M is greater than or equal to 2 and N is greater than or equal to 1.

[0081] The hole-making process is as follows: using a vibratory punch to create holes;

[0082] The connection process is as follows: when the circumferential groove 111 on the working sleeve of the vibratory impactor is exposed from the non-working sleeve, the detachable lifting ring 7 is inserted into the exposed circumferential groove 111, and the non-working sleeve with the smallest diameter is released to the side of the detachable lifting ring 7 away from the ground. The released non-working sleeve is connected to the working sleeve by gravity through the detachable lifting ring 7 and becomes a new working sleeve. The new working sleeve, together with the original working sleeve and the vibratory impactor 2, forms a new vibratory impactor.

[0083] 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-updatable vibratory compaction body. This length-updatable vibratory compaction body enables multi-segment vibratory compaction drilling, achieving ultra-deep vibratory compaction construction with depths exceeding 100 meters. Compared to conventional construction processes, the length of a single sleeve in the multi-segment sleeve 1 can be similar to the length of the guide rod in conventional processes, thus avoiding manufacturing and transportation difficulties. In this embodiment, the drilling and connection processes are performed alternately. In this construction process, the height of the pile driver frame 6 is approximately 2 to 3 meters greater than the length of a single sleeve.

[0084] 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. This gravity connection structure forms a vibratory compaction body with an updatable length. Based on this updatable vibratory compaction body, a multi-segment vibratory compaction construction process is implemented to form ultra-deep vibratory compaction holes with a depth of up to 100 meters. Another unique feature of this vibratory compaction construction process is that the total weight of the vibratory compaction body formed by the sleeve and vibratory compactor 2 in the working state changes with the position of the vibratory compaction depth range. The deeper the vibratory compactor 2 is in the depth range, the greater the total weight of the vibratory compaction body formed by the sleeve and vibratory compactor 2 in the working state. This can effectively overcome the different resistance caused by different strata depths during vibratory compaction, and can improve the efficiency and quality of vibratory compaction.

[0085] In a preferred example embodiment, such as Figure 1 As shown, the multi-stage vibratory punching hole-making process also includes M hole-cleaning processes, which are the same number of times as the hole-making process, with each hole-cleaning process following the hole-making process.

[0086] The vibratory body includes a flushing port provided on the vibratory mixer 2;

[0087] The hole cleaning process involves repeatedly rinsing the vibratory holes created during the hole-making process using the flushing nozzle on the vibratory punch 2. This hole cleaning process, performed after the hole-making process, avoids the need for repeated connection and disassembly of multiple sleeve sections compared to the conventional method of cleaning after completing the entire hole-making process.

[0088] In a preferred embodiment, when M is 3, N is 2, and there are 3 sleeves, the 3 sleeves are the sleeve with the largest diameter 13, the sleeve with the second largest diameter 12, and the sleeve with the smallest diameter 11. The multi-segment vibratory punching hole-making process is as follows:

[0089] 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.

[0090] 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.

[0091] S3, Secondary Hole Formation: Using the new vibratory punch in S2, a second hole formation is performed based on the first hole formation;

[0092] 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 transforms into a new working sleeve. The three sleeves and the vibratory impactor 2 form a new vibratory impactor.

[0093] 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.

[0094] like Figures 1 to 7 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.

[0095] In a preferred example embodiment, such as Figure 1 As shown, the hole cleaning process is performed three times, and the three hole cleaning processes are as follows:

[0096] 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;

[0097] 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;

[0098] 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.

[0099] 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.

[0100] In a preferred embodiment, a multi-stage vibratory compaction pile-making process is also included:

[0101] The multi-stage vibratory compaction pile manufacturing process includes M filling processes and N disassembly processes, where M is greater than or equal to 2 and N is greater than or equal to 1.

[0102] Filling process: Fill the vibratory holes created by the vibratory punching body with filler material, and then use the vibratory punching body to vibrate and punch in the vibratory holes.

[0103] Disassembly process: When the detached lifting ring 7, which is attached to the working sleeve of the vibratory compactor, rises to the preset height, the working sleeve with the largest diameter is lifted or raised, and the detached lifting ring 7 is disassembled from the circumferential groove 111. The working sleeve with the largest diameter becomes a suspended non-working sleeve, and the original working sleeve becomes a new working sleeve. The new working sleeve and the vibratory compactor 2 form a new vibratory compactor. In the filling process of the multi-segment vibratory compaction pile making process, for every meter of filling, the vibratory compactor needs to vibrate downwards by half a meter so that the vibratory compactor 2 can squeeze the filling material into the stratum around the vibratory compaction hole, ensuring the quality of the vibratory compaction pile. In this embodiment, the overall depth of the vibratory compaction pile formed by the three-segment vibratory compaction pile, the two-segment vibratory compaction pile, and the one-segment vibratory compaction pile can reach 100 meters. In this embodiment, the filling process and the disassembly process are performed alternately.

[0104] Preferably, when M is 3 and N is 2, the three sleeves are the sleeve with the largest diameter 13, the sleeve with the second largest diameter 12, and the sleeve with the smallest diameter 11, respectively. The multi-segment vibratory compaction pile-making process is as follows:

[0105] 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.

[0106] 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.

[0107] S8, Secondary packing: Using the new vibratory impactor in S7, secondary packing is carried out on the basis of primary packing.

[0108] 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.

[0109] S10, third-stage packing, utilizes the new vibratory compactor in S9, performing third-stage packing based on second-stage packing. For example... Figures 1 to 7 As shown, during the first filling, the vibratory compaction depth of the filling is within the three-section area, forming a three-section vibratory compaction pile. During the second filling, the vibratory compaction depth of the filling is within the two-section area. After the hole is drilled, a vibratory compaction pile is formed that integrates the three-section and the two-section sections. During the third filling, the vibratory compaction depth of the filling is within the one-section area. After the filling is completed, a vibratory compaction pile that integrates the one-section, two-section, and three-section sections is formed. The depth of a vibratory compaction pile that integrates the one-section, two-section, and three-section sections can reach 100 meters.

[0110] Preferably, in the multi-segment vibratory compaction drilling process and the multi-segment vibratory compaction pile driving process, the steel cable 3 needs to lift the working sleeve with the smallest diameter. In the case of a non-working sleeve, the guide support structure 5 and / or the guide hanging structure 4 are also needed to support and hang the non-working sleeve. In this embodiment, two steel cables 3 are provided. In some embodiments, three or more steel cables 3 can be provided, and the three or more steel cables 3 are evenly distributed along the circumference of the vibratory compactor 2. During the construction processes of the first drilling process, the second drilling process, the first filling process, and the second filling process, as well as during the connection and disassembly processes, the guide support structure 5 and / or the guide hanging structure 4 are needed to support and hang the non-working sleeve to prevent it from sliding directly to the ground under gravity.

[0111] In this embodiment, as Figure 2 As shown, the guide structure 4 is fixedly connected to the top of the sleeve 13 with the largest diameter, and both the guide structure 4 and the guide support structure 5 are slidably connected to the pile in the vertical direction. The column is a conventional technology and will not be described in detail here.

[0112] Understandably, during the first drilling and third filling processes, as well as the first connection and second disassembly processes, the guide support structure 5 needs to lift the non-working secondary diameter sleeve 12, and the guide hanging structure 4 needs to hang the non-working largest diameter sleeve 13 to prevent the non-working sleeve from sliding to the ground under gravity. During the second drilling and second filling processes, as well as the second connection and first disassembly processes, the guide support structure 5 and guide hanging structure 4 need to lift and hang the non-working largest diameter sleeve 13 to prevent it from sliding to the ground. During the third drilling and third filling processes, the guide support structure 5 and guide hanging structure 4 need to guide the largest diameter working sleeve. During the multiple hole-making and filling processes, the guide support structure 5 and the guide hanging structure 4 lift and hang the non-working sleeve. Since a part of the working sleeve with the largest diameter is inside the non-working sleeve, the working sleeve can be guided, thus preventing the vibratory compactor 2 from shifting during the hole-making and filling processes, which would affect the vibratory compaction quality and efficiency during the hole-making and filling processes.

[0113] Understandably, in the hole-making and filling processes, the working sleeve with the largest diameter is pressed against the first top surface 72 of the detached lifting ring 7, and the first bottom surface 71 of the detached lifting ring 7 is pressed against the bottom surface of the circumferential annular groove 111. Therefore, a force connection is formed inside the working sleeve in the direction of gravity. The steel cable 3, fixed to the working sleeve with the smallest diameter, can lift all the working sleeves and the detached lifting ring 7. Under the action of gravity, the working sleeves and the detached lifting ring 7 can form a single vibratory body for vibratory compaction. For example... Figure 5 As shown in this embodiment, after being installed on the inner cylinder groove, the lifting ring body has a circular shape.

[0114] In a preferred embodiment, in the hole-making process of the multi-segment vibratory compaction hole-making process and the filling process of the multi-segment vibratory compaction pile-making process, in the absence of a non-working sleeve, it is necessary to use the guide support structure 5 and / or the guide hanger structure 4 to guide the working sleeve with the largest diameter. It is understood that during the three hole-making processes and three filling processes, the guide support structure 5 and the guide hanger structure 4 can be used directly to guide the working sleeve with the largest diameter.

[0115] Preferably, in the multi-segment vibratory compaction drilling process and the multi-segment vibratory compaction pile making process, the depth of each drilling segment and the depth of each filling segment range from 17 meters to 30 meters. In this embodiment, the height of the first-segment vibratory compaction hole, the second-segment vibratory compaction hole, the third-segment vibratory compaction hole, the first-segment vibratory compaction pile, the second-segment vibratory compaction pile, and the third-segment vibratory compaction pile can be 17 meters, 20 meters, 25 meters, 30 meters, or other heights.

[0116] Preferably, in the multi-stage vibratory punching hole-making process, before the initial hole-making process, all non-working sleeves need to be lifted up using the guide support structure 5, and the non-working sleeves with the smallest diameter are released sequentially in the subsequent connection process.

[0117] In the dismantling process of the multi-stage vibratory pile driving process, while the guide support structure 5 holds all the non-working sleeves tightly, the guide support structure 5 is used to lift the working sleeve with the largest diameter, thus transforming the working sleeve with the largest diameter into the non-working sleeve with the smallest diameter.

[0118] In this embodiment, all non-working sleeves are lifted up at once before the initial hole-making process of the multi-segment vibratory compaction pile-making process, and the smallest diameter non-working sleeves are released sequentially in the subsequent connection process. This avoids adjusting the position of the guide support structure 5 in the connection process, thus improving connection efficiency. In the disassembly process of the multi-segment vibratory compaction pile-making process, while the guide support structure 5 holds all the non-working sleeves, it also lifts the largest diameter working sleeve. This allows the guide support structure 5 to lift the largest diameter working sleeves sequentially in the multi-segment vibratory compaction pile-making process and transform the largest diameter working sleeve into the smallest diameter non-working sleeve, thereby improving disassembly efficiency.

[0119] 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 111 is defined as A3;

[0120] The inner and outer diameters of the sleeve with the smallest diameter in the non-working state are defined as B1 and B2, respectively;

[0121] The inner and outer diameters of the lifting ring are defined as D1 and D2, respectively.

[0122] 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:

[0123] Relationship 1: A1 < A3 = D1 < A2 < B1 < D2;

[0124] Relationship 2: A1 < A3 = D1 < A2 < B1 < B2.

[0125] In this embodiment, refer to Figure 4 and Figure 5 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.

[0126] Example 2:

[0127] like Figures 11 to 14As shown, in this embodiment, M is 2, N is 1, and there are two sleeves: the sleeve with the largest diameter (13) and the sleeve with the smallest diameter (11). The multi-segment vibratory punching hole-making process is as follows:

[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 secondary hole formation is performed based on the first hole formation.

[0131] In a preferred example embodiment, such as Figure 11 As shown, it also includes two hole cleaning processes, which are specifically as follows:

[0132] 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;

[0133] 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.

[0134] In a preferred embodiment, when M is 2, N is 1, and the two sleeves are the sleeve with the largest diameter 13 and the sleeve with the smallest diameter 11, the multi-segment vibratory compaction pile-making process is as follows:

[0135] 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.

[0136] 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.

[0137] S8, secondary packing, utilizes the new vibratory impactor in S7 to perform secondary packing based on primary packing.

[0138] 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.
