Description

Technical Field

[0001] This invention relates to the field of concrete pile breaking technology, and more specifically, to a system and method for breaking the pile head of a cast-in-place concrete pile. Background Technology

[0002] When casting cast-in-place piles, the top elevation of the pile should be 0.5-1.0m higher than the designed top elevation to ensure the strength of the pile head concrete. However, the portion of the pile head that is higher than the designed top elevation must be removed during subsequent construction processes. The work of removing this portion of the pile head concrete is called breaking the pile head.

[0003] The general method for breaking up the pile head of a cast-in-place pile is as follows: the cutting elevation position of the pile head is determined manually, a cutting machine is used to make a circumferential cut at the cutting elevation position, a V-shaped opening is chiseled out of the cutting seam, a pneumatic pick is inserted to drill a hole, a steel chisel is inserted and a hammer is used to pry it open, a crane is used to lift the cut pile head concrete to the designated location, and then the cross-section of the cut pile head is corrected and cleaned with machinery. Since a large amount of dust is generated during the cutting of the pile head, a dust suppression fog cannon is usually used to spray dust at the designated construction site.

[0004] While traditional methods can cut the pile head, they can also endanger the health of construction workers. After the pile head is broken, the effective pile top surface is uneven, and loose stones and cement blocks are produced on the cut surface. These require manual repair, washing, and cleaning, making the process time-consuming and inefficient. Summary of the Invention

[0005] In view of this, the present invention provides a system and method for breaking up concrete cast-in-place pile heads, in order to solve the problem of low quality and efficiency in breaking up concrete cast-in-place pile heads in the prior art.

[0006] This invention proposes a system for breaking up the pile head of a cast-in-place concrete pile, comprising:

[0007] The system comprises a detection module for collecting data on pile head diameter and height, and the retraction speed of the hydraulic pile breaker; a processing module for setting the initial compression force of the hydraulic pile breaker based on the acquired pile head diameter and height; a control module for issuing commands to the hydraulic pile breaker based on the compression force set by the processing module; and an execution module for receiving the commands issued by the control module and determining whether to execute them.

[0008] The processing module is configured with a standard preset pile head diameter D0, a preset pile head diameter difference matrix D, and a preset initial compression force matrix N. The processing module is also used to calculate the pile head diameter difference ΔD based on the difference between the actual pile head diameter d obtained by the detection module and the standard preset pile head diameter D0, and to select a preset initial compression force as the initial compression force N of the hydraulic pile breaker based on the relationship between the pile head diameter difference ΔD and each preset pile head diameter difference D.

[0009] Further, the processing module sets D(D1, D2, D3, D4, D5), where D1 is the first preset pile head diameter difference, D2 is the second preset pile head diameter difference, D3 is the third preset pile head diameter difference, D4 ​​is the fourth preset pile head diameter difference, and D5 is the fifth preset pile head diameter difference, and D1 < D2 < D3 < D4 < D5; and sets N(N1, N2, N3, N4, N5), where N1 is the first preset initial compression force, N2 is the second preset initial compression force, N3 is the third preset initial compression force, N4 is the fourth preset initial compression force, and N5 is the fifth preset initial compression force, and N1 < N2 < N3 < N4 < N5.

[0010] Furthermore, the processing module selects a preset initial compression force as the initial compression force N of the hydraulic pile breaker based on the following conditions:

[0011] When (d-D0) < D1, the first preset initial compression force N1 is set as the initial compression force of the hydraulic pile breaker;

[0012] When D1≤(d-D0)<D2, the second preset initial compression force N2 is set as the initial compression force of the hydraulic pile breaker;

[0013] When D2≤(d-D0)<D3, the third preset initial compression force N3 is set as the initial compression force of the hydraulic pile breaker;

[0014] When D3≤(d-D0)<D4, the fourth preset initial compression force N4 is set as the initial compression force of the hydraulic pile breaker;

[0015] When D4≤(d-D0)<D5, the fifth preset initial compression force N5 is set as the initial compression force of the hydraulic pile breaker.

[0016] Furthermore, the processing module is also used to adjust the initial compression force of the hydraulic pile breaker based on the collected pile head height:

[0017] The pile head height collected by the detection module is set to h, and the pile head height matrix H and the first adjustment coefficient matrix X are preset.

[0018] For the preset pile head height matrix H, set H (H1, H2, H3, H4), where H1 is the first preset pile head height, H2 is the second preset pile head height, H3 is the third preset pile head height, H4 is the fourth preset pile head height, and H1 < H2 < H3 < H4;

[0019] For the preset primary adjustment coefficient matrix X, set X (X1, X2, X3, X4, X5), where X1 is the first preset primary adjustment coefficient, X2 is the second preset primary adjustment coefficient, X3 is the third preset primary adjustment coefficient, X4 is the fourth preset primary adjustment coefficient, and X1 < X2 < X3 < X4;

[0020] The processing module selects each preset primary adjustment coefficient according to the magnitude relationship between each preset pile head height and the pile head height h collected by the detection module.

[0021] Further, the processing module selects each preset primary adjustment coefficient according to the following relationship between each preset pile head height and the pile head height h collected by the detection module:

[0022] When h < H1, set the first preset primary adjustment coefficient X1 as the adjustment coefficient of the hydraulic pile breaker. At this time, the compression force of the hydraulic pile breaker is Ni × X1, i = 1, 2, 3, 4, 5;

[0023] When H1 ≤ h < H2, set the second preset primary adjustment coefficient X2 as the adjustment coefficient of the hydraulic pile breaker. At this time, the compression force of the hydraulic pile breaker is Ni × X2, i = 1, 2, 3, 4, 5;

[0024] When H2 ≤ h < H3, set the third preset primary adjustment coefficient X3 as the adjustment coefficient of the hydraulic pile breaker. At this time, the compression force of the hydraulic pile breaker is Ni × X3, i = 1, 2, 3, 4, 5;

[0025] When H3 ≤ h < H4, set the fourth preset primary adjustment coefficient X4 as the adjustment coefficient of the hydraulic pile breaker. At this time, the compression force of the hydraulic pile breaker is Ni × X4, i = 1, 2, 3, 4, 5.

[0026] Further, after the execution module obtains the instruction issued to the hydraulic pile breaker, when Ni × Xj = (μd 2 hg) / 4, the execution module permits the execution of the instruction issued by the control module to the hydraulic pile breaker, and the hydraulic pile breaker starts to contract towards the center of the cast-in-place pile to break the cast-in-place pile; when Ni × Xj < (μd 2 hg) / 4, the execution module prohibits the execution of the instruction issued by the control module to the hydraulic pile breaker;

[0027] Where μ is the coefficient of kinetic friction; d is the actual pile head diameter; h is the pile head height collected by the detection module; g is the gravitational acceleration; i = 1, 2, 3, 4, 5; j = 1, 2, 3, 4.

[0028] Furthermore, after the hydraulic pile breaker starts the breaking process, the processing module is also used to obtain the real-time retraction speed v of the hydraulic pile breaker, the preset retraction speed matrix V, and the secondary adjustment coefficient matrix Y;

[0029] For the preset contraction speed matrix V, V is set as V(V1, V2, V3, V4), where V1 is the first preset contraction speed, V2 is the second preset contraction speed, V3 is the third preset contraction speed, and V4 is the fourth preset contraction speed, and V1 < V2 < V3 < V4.

[0030] For the preset quadratic adjustment coefficient matrix Y, set Y(Y1, Y2, Y3, Y4, Y5), where Y1 is the first preset quadratic adjustment coefficient, Y2 is the second preset quadratic adjustment coefficient, Y3 is the third preset quadratic adjustment coefficient, and Y4 is the fourth preset quadratic adjustment coefficient, and Y1 < Y2 < Y3 < Y4.

[0031] The processing module selects preset secondary adjustment coefficients based on the relationship between the real-time contraction speed v of the hydraulic pile breaker and each preset contraction speed.

[0032] Furthermore, the processing module selects preset secondary adjustment coefficients according to the following conditions: when v < V1, the fourth preset secondary adjustment coefficient Y1 is set as the adjustment coefficient of the hydraulic pile breaker, and the compression force of the hydraulic pile breaker is Ni×Xj×Y4.

[0033] When V1≤v<V2, the third preset secondary adjustment coefficient Y3 is set as the adjustment coefficient of the hydraulic pile breaker. At this time, the compression force of the hydraulic pile breaker is Ni×Xj×Y3.

[0034] When V2≤v<V3, the second preset secondary adjustment coefficient Y2 is set as the adjustment coefficient of the hydraulic pile breaker. At this time, the compression force of the hydraulic pile breaker is Ni×Xj×Y2.

[0035] When V3≤v<V4, the first preset secondary adjustment coefficient Y1 is set as the adjustment coefficient of the hydraulic pile breaker. At this time, the compression force of the hydraulic pile breaker is Ni×Xj×Y1.

[0036] Where i = 1, 2, 3, 4, 5; j = 1, 2, 3, 4.

[0037] This invention provides a system for breaking up the head of a cast-in-place concrete pile. Compared with existing technologies, its advantages are as follows:

[0038] By processing the preset pile head diameter D0, pile head diameter difference matrix D, and preset initial compression force matrix N within the module, the system can intelligently select an appropriate initial compression force based on the actual pile head diameter. This allows the system to flexibly adjust the operating parameters of the hydraulic pile breaker according to different pile head diameters, improving the system's intelligence and adaptability, and also contributing to improved breaking efficiency and quality.

[0039] On the other hand, the present invention provides a method for breaking up the pile head of a cast-in-place concrete pile, which is applied to the above-mentioned system for breaking up the pile head of a cast-in-place concrete pile, and includes:

[0040] The hydraulic pile breaker is placed on the cast-in-place pile. The initial compression force is set based on the diameter of the pile head, and then the initial compression force is adjusted once according to the height of the pile head.

[0041] The hydraulic pile breaker retracts towards the center of the cast-in-place pile, initiating the breaking process. At this point, the retraction force of the hydraulic pile breaker is adjusted a second time according to the retraction speed.

[0042] Furthermore, when the detection module detects that the retraction speed of the hydraulic pile breaker is 0, the retraction force is less than the minimum Newton force required to break the cast-in-place pile. After adjusting the compression force to the maximum value, if the retraction speed is still 0, the operation stops; if the retraction speed is not 0, the current state is maintained.

[0043] It is understandable that the above-mentioned concrete pile head breaking system and method have the same beneficial effects, and will not be elaborated further here. Attached Figure Description

[0044] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on the provided drawings without creative effort.

[0045] Figure 1 This is a functional framework diagram of the concrete-filled pile head breaking system in an embodiment of the present invention;

[0046] Figure 2 This is a flowchart of the method for breaking the pile head of a concrete cast-in-place pile in an embodiment of the present invention. Detailed Implementation

[0047] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] See Figure 1-2 As shown, a preferred embodiment of the present invention provides a concrete pile head breaking system, comprising: a detection module for acquiring pile head diameter and height, and the contraction speed of a hydraulic pile breaker; a processing module for setting the initial compression force of the hydraulic pile breaker based on the acquired pile head diameter and height; a control module for issuing commands to the hydraulic pile breaker according to the compression force set by the processing module; and an execution module for acquiring the commands issued by the control module to the hydraulic pile breaker and determining whether to execute them.

[0049] The processing module is set with a standard preset pile head diameter D0, and preset pile head diameter difference matrix D and preset initial compression force matrix N;

[0050] The processing module is also used to calculate the pile head diameter difference ΔD based on the difference between the actual pile head diameter d obtained by the detection module and the standard preset pile head diameter D0, and to select a preset initial compression force as the initial compression force of the hydraulic pile breaker based on the relationship between the pile head diameter difference ΔD and the preset pile head diameter differences.

[0051] Specifically: For the preset pile head diameter difference matrix D, the processing module sets D(D1, D2, D3, D4, D5), where D1 is the first preset pile head diameter difference, D2 is the second preset pile head diameter difference, D3 is the third preset pile head diameter difference, D4 ​​is the fourth preset pile head diameter difference, and D5 is the fifth preset pile head diameter difference, and D1 < D2 < D3 < D4 < D5;

[0052] For a preset initial compression force matrix N, set N(N1, N2, N3, N4, N5), where N1 is the first preset initial compression force, N2 is the second preset initial compression force, N3 is the third preset initial compression force, N4 is the fourth preset initial compression force, and N5 is the fifth preset initial compression force, and N1 < N2 < N3 < N4 < N5.

[0053] The processing module selects a preset initial compression force as the initial compression force of the hydraulic pile breaker based on the following conditions: when (d-D0) < D1, the first preset initial compression force N1 is set as the initial compression force of the hydraulic pile breaker.

[0054] When D1≤(d-D0)<D2, the second preset initial compression force N2 is set as the initial compression force of the hydraulic pile breaker;

[0055] When D2≤(d-D0)<D3, the third preset initial compression force N3 is set as the initial compression force of the hydraulic pile breaker;

[0056] When D3≤(d-D0)<D4, the fourth preset initial compression force N4 is set as the initial compression force of the hydraulic pile breaker;

[0057] When D4≤(d-D0)<D5, the fifth preset initial compression force N5 is set as the initial compression force of the hydraulic pile breaker.

[0058] Understandably, by processing the preset pile head diameter difference matrix D and preset initial compression force matrix N within the module, the system can intelligently select the initial compression force based on the difference ΔD between the actual pile head diameter and the standard preset pile head diameter. This gives the system adaptability, allowing it to flexibly adjust the initial compression force of the hydraulic pile breaker according to the actual pile head conditions, improving pile breaking efficiency and adaptability, as well as breaking quality and efficiency. Through different stages of the preset initial compression force matrix N, the system selects the initial compression force in stages based on the magnitude of the difference ΔD between the actual pile head diameter and the standard preset pile head diameter. This helps adapt to pile heads with different diameter ranges, ensuring that the pile breaker can break piles with the optimal initial compression force under different working conditions, improving the accuracy and efficiency of pile breaking.

[0059] Traditional methods of breaking pile heads may require extensive manual labor, including positioning, cutting, and chiseling. This system, however, automatically collects the pile head diameter and height, and intelligently sets the initial compression force using a processing module, reducing reliance on manual operation. This not only improves operational safety but also reduces human error and alleviates the labor intensity for workers. Through intelligent, staged adjustments to the preset initial compression force, the system can adapt to pile heads of different diameters more quickly and accurately, thereby improving the operating efficiency of the hydraulic pile breaker. The system can dynamically adjust the compression force according to actual conditions during the breaking process, avoiding excessive or insufficient force application, thus improving overall operating efficiency.

[0060] The concrete pile head breaking system of the present invention is mainly applied to hydraulic pile breakers.

[0061] In some embodiments, it also includes:

[0062] The processing module is also used to adjust the initial compression force of the hydraulic pile breaker based on the collected pile head height:

[0063] The pile head height collected by the detection module is set to h, and the pile head height matrix H and the first adjustment coefficient matrix X are preset.

[0064] For the preset pile head height matrix H, set H (H1, H2, H3, H4), where H1 is the first preset pile head height, H2 is the second preset pile head height, H3 is the third preset pile head height, H4 is the fourth preset pile head height, and H1 < H2 < H3 < H4;

[0065] For the preset primary adjustment coefficient matrix X, set X (X1, X2, X3, X4, X5), where X1 is the first preset primary adjustment coefficient, X2 is the second preset primary adjustment coefficient, X3 is the third preset primary adjustment coefficient, X4 is the fourth preset primary adjustment coefficient, and X1 < X2 < X3 < X4;

[0066] The processing module selects each preset primary adjustment coefficient according to the size relationship between each preset pile head height and the pile head height h collected by the detection module.

[0067] In some embodiments, when h < H1, set the first preset primary adjustment coefficient X1 as the adjustment coefficient of the hydraulic pile breaker. At this time, the compression force of the hydraulic pile breaker is Ni × X1, i = 1, 2, 3, 4, 5;

[0068] When H1 ≤ h < H2, set the second preset primary adjustment coefficient X2 as the adjustment coefficient of the hydraulic pile breaker. At this time, the compression force of the hydraulic pile breaker is Ni × X2, i = 1, 2, 3, 4, 5;

[0069] When H2 ≤ h < H3, set the third preset primary adjustment coefficient X3 as the adjustment coefficient of the hydraulic pile breaker. At this time, the compression force of the hydraulic pile breaker is Ni × X3, i = 1, 2, 3, 4, 5;

[0070] When H3 ≤ h < H4, set the fourth preset primary adjustment coefficient X4 as the adjustment coefficient of the hydraulic pile breaker. At this time, the compression force of the hydraulic pile breaker is Ni × X4, i = 1, 2, 3, 4, 5.

[0071] It can be understood that during the construction of cast-in-place piles, the system can intelligently select a suitable primary adjustment coefficient according to the actually collected pile head height, so that the hydraulic pile breaker performs pile breaking with the optimal initial compression force within different height ranges. Such a design enhances the adaptability of the system to the change of pile head height and improves the efficiency and accuracy of pile breaking.

[0072] [[ID=第24]]In some embodiments, after the execution module obtains the instruction issued to the hydraulic pile breaker, it determines whether to start the breaking process by comparing the current compression force Ni × Xj of the hydraulic pile breaker with the relationship of (μd 2 hg) / 4;

[0073] Where μ is the coefficient of kinetic friction; d is the actual pile head diameter; h is the pile head height collected by the detection module; g is the acceleration due to gravity; i = 1, 2, 3, 4, 5; j = 1, 2, 3, 4.

[0074] In some embodiments, if Ni×Xj=(μd) 2 If hg) / 4, then the execution module allows the execution of the instructions issued by the control module to the hydraulic pile breaker, and the hydraulic pile breaker begins to retract towards the center of the cast-in-place pile to break it; if Ni×Xj<(μd) 2 If hg) / 4, then the execution module is prohibited from executing the instructions issued by the control module to the hydraulic pile breaker.

[0075] It should be noted that Ni×Xj represents the current compressive force of the hydraulic pile breaker, while (μd) 2 hg) / 4 is the minimum force required to ensure that the cast-in-place pile does not slip.

[0076] In some embodiments, the processing module is further configured to acquire the real-time contraction speed v of the hydraulic pile breaker, the preset contraction speed matrix V, and the secondary adjustment coefficient matrix Y of the hydraulic pile breaker after the hydraulic pile breaker starts the breaking process.

[0077] For a preset contraction speed matrix V, set V(V1, V2, V3, V4), where V1 is the first preset contraction speed, V2 is the second preset contraction speed, V3 is the third preset contraction speed, and V4 is the fourth preset contraction speed, and V1 < V2 < V3 < V4.

[0078] For a preset quadratic adjustment coefficient matrix Y, set Y(Y1, Y2, Y3, Y4, Y5), where Y1 is the first preset quadratic adjustment coefficient, Y2 is the second preset quadratic adjustment coefficient, Y3 is the third preset quadratic adjustment coefficient, and Y4 is the fourth preset quadratic adjustment coefficient, and Y1 < Y2 < Y3 < Y4.

[0079] The processing module selects preset secondary adjustment coefficients based on the relationship between the real-time retraction speed v of the hydraulic pile breaker and each preset retraction speed.

[0080] In some embodiments, when v < V1, a fourth preset secondary adjustment coefficient Y1 is set as the adjustment coefficient of the hydraulic pile breaker, and the compression force of the hydraulic pile breaker is Ni×Xj×Y4.

[0081] When V1≤v<V2, the third preset secondary adjustment coefficient Y3 is set as the adjustment coefficient of the hydraulic pile breaker. At this time, the compression force of the hydraulic pile breaker is Ni×Xj×Y3.

[0082] When V2≤v<V3, the second preset secondary adjustment coefficient Y2 is set as the adjustment coefficient of the hydraulic pile breaker. At this time, the compression force of the hydraulic pile breaker is Ni×Xj×Y2.

[0083] When V3≤v<V4, the first preset secondary adjustment coefficient Y1 is set as the adjustment coefficient of the hydraulic pile breaker. At this time, the compression force of the hydraulic pile breaker is Ni×Xj×Y1.

[0084] Where i = 1, 2, 3, 4, 5; j = 1, 2, 3, 4.

[0085] Understandably, by acquiring the real-time retraction speed of the hydraulic pile breaker, the system can instantly understand its working status during the pile breaking process. This helps the system make timely adjustments to meet actual work requirements. Based on the relationship between the real-time retraction speed of the hydraulic pile breaker and the preset retraction speed matrix, an appropriate secondary adjustment coefficient is selected. In this way, the system can individually adjust the compression force of the hydraulic pile breaker according to different retraction speeds. Specifically: when the retraction speed is fast (v < V1), the system applies a larger secondary adjustment coefficient Y4 to increase the compression force of the hydraulic pile breaker. As the retraction speed decreases, the secondary adjustment coefficient is gradually reduced, causing the compression force of the hydraulic pile breaker to decrease accordingly, better adapting to different retraction speeds. By dynamically adjusting the compression force of the hydraulic pile breaker according to real-time conditions, the system can more effectively break pile heads. This helps improve work efficiency and ensures that appropriate pressure is maintained under different conditions, thereby improving work safety and stability. By automatically adjusting the compression force of the hydraulic pile breaker, the system can reduce manual intervention by operators. This helps reduce operational complexity and improve the level of automation in construction.

[0086] In some embodiments, when v=0, the processing module sets the compression force of the hydraulic pile breaker to N5×X4×Y4 and determines whether v is 0;

[0087] If the judgment result is not 0, the hydraulic pile breaker will maintain its current working state; if the judgment result is 0, the hydraulic pile breaker will be terminated.

[0088] In summary, the pile breaking system of this invention can intelligently select the initial compression force based on the difference ΔD between the actual pile head diameter and the standard preset pile head diameter. During the breaking process, by acquiring the real-time contraction speed v of the hydraulic pile breaker and adjusting it according to the preset contraction speed matrix V and the secondary adjustment coefficient matrix Y, the compression force of the hydraulic pile breaker can be monitored and adjusted in real time. This helps ensure that the system can dynamically adapt to changes in the pile head during different stages of pile breaking, improving the system's stability and operational controllability. The processing module adjusts the initial compression force of the hydraulic pile breaker based on the collected pile head height. Through the preset pile head height matrix H and the preset primary adjustment coefficient matrix X, the system can intelligently adjust the initial compression force of the hydraulic pile breaker according to the pile head height. In this way, the system has a certain degree of adaptability when dealing with pile heads of different heights, improving the system's applicability and operational flexibility. By collecting parameters such as pile head diameter, pile head height, and the contraction speed of the hydraulic pile breaker through the detection module, and combining them with the intelligent processing and control module, the system can achieve precise control of the hydraulic pile breaker's operation during the pile breaking process. This helps improve the efficiency of pile breaking, reduce energy consumption, and ensure the safety and stability of the operation.

[0089] This invention also provides a method for breaking up the head of a cast-in-place concrete pile, applied in the aforementioned system for breaking up the head of a cast-in-place concrete pile, comprising:

[0090] The hydraulic pile breaker is placed on the cast-in-place pile. The initial compression force is set based on the diameter of the pile head, and then the initial compression force is adjusted once according to the height of the pile head.

[0091] The hydraulic pile breaker retracts towards the center of the cast-in-place pile, initiating the breaking process. At this point, the retraction force of the hydraulic pile breaker is adjusted a second time according to the retraction speed.

[0092] In some embodiments, when the detection module detects that the contraction speed of the hydraulic pile breaker is 0, the contraction force is less than the minimum Newton force required to break the cast-in-place pile. After adjusting the compression force to the maximum value, if the contraction speed is still 0, the work is stopped; if the contraction speed is not 0, the current state is maintained.

[0093] The relevant parts of the method embodiments and the system embodiments described above can be referred to each other, and will not be repeated here.

[0094] First, by collecting parameters such as pile head diameter, pile head height, and the contraction speed of the hydraulic pile breaker through the detection module, a comprehensive understanding of the actual condition of the cast-in-place pile can be obtained. This helps to more accurately determine the initial compression force of the hydraulic pile breaker, improving the efficiency and accuracy of the breaking process. Second, the processing module's preset standard pile head diameter D0, pile head diameter difference matrix D, and preset initial compression force matrix N, as well as the method of calculating the pile head diameter difference ΔD based on the difference between the actual pile head diameter and the standard preset pile head diameter, can intelligently select an appropriate initial compression force according to specific circumstances. In this way, the system can better adapt to cast-in-place concrete piles of different specifications and conditions.

[0095] Furthermore, the processing module adjusts the initial compression force of the hydraulic pile breaker based on the collected pile head height. By using a preset pile head height matrix H and a preset primary adjustment coefficient matrix X, the system exhibits a degree of adaptability. This helps adjust the compression force of the hydraulic pile breaker under different pile head conditions, improving the system's flexibility and applicability. Finally, after the hydraulic pile breaker begins the breaking process, the system acquires the real-time contraction speed v and adjusts it according to a preset contraction speed matrix V and a secondary adjustment coefficient matrix Y, enabling more intelligent control of the hydraulic pile breaker's operation. In this way, the system can adjust the compression force in real time during the breaking process, ensuring a smooth pile breaking process and improving operational safety and controllability.
