Description

Technical Field

[0001] This utility model relates to a soft soil foundation pile foundation correction device, and in particular to a soft soil foundation pile foundation correction device applied in the field of pile driving equipment. Background Technology

[0002] In soft soil foundation construction, the verticality and stability of the pile foundation support system directly affect the overall structural safety. The construction process of driving precast piles or cast-in-place piles into the underground soil layer using specialized pile driving equipment has the core function of transferring the load of the superstructure to the deep, solid soil or rock layer to solve the problem of insufficient bearing capacity in soft soil foundations and ensure the stability and safety of the building structure.

[0003] Chinese patent CN211549582U discloses an integrated drilling and piling machine for soft soil foundations containing rocks, specifically relating to the field of drilling and piling technology. It includes a cuboid to reduce the frictional resistance of the slider and the groove; the addition of a second fixed plate to allow the slide rod to swing; the addition of a first sliding sleeve, a second sliding sleeve, and the slide rod to allow the movable plate to drive the support rod to move; and the addition of a stabilizing block to increase the stability of the support rod.

[0004] Chinese patent CN201354458Y discloses a small-scale piling device, including a base, frame, winch, and pile hammer. The winch's wire rope is connected to the pile hammer via a guide pulley on the upper part of the frame. The frame is less than 2.20m high. Addressing the foundation settlement problem of equipment in substations with silt or soft soil foundations, this device overcomes the limitation of inconvenient piling for foundation reinforcement in the special construction environment of operating substations. It is simple to operate, compact in size, and also well-suited for foundation settlement reinforcement and correction of industrial production equipment.

[0005] Traditional piling equipment lacks a real-time monitoring mechanism and relies heavily on manual visual observation or post-construction measurement. It is difficult to detect tilting deviations in a timely manner during the piling process. Often, the deviation is only noticed after multiple steel sheet piles are spliced ​​together. At this point, correction requires removal and re-driving, which not only wastes materials and construction time but also exacerbates the damage to soft soil structures due to repeated disturbances. Utility Model Content

[0006] The technical problem that this utility model aims to solve in view of the above-mentioned prior art is that traditional piling equipment lacks a real-time monitoring mechanism and relies mostly on manual visual observation or post-event measurement. It is difficult to detect tilting deviations in a timely manner during the piling process. Often, the deviation is only noticed after multiple steel sheet piles are spliced ​​together. At this time, correction requires removal and re-driving, which not only wastes materials and construction time, but also aggravates the damage to soft soil structures due to repeated disturbance.

[0007] To address the aforementioned problems, this utility model provides a pile foundation correction device for soft soil foundations, comprising a pile driving equipment assembly, an angle monitoring assembly at the side of the pile driving equipment assembly, an accessory moving assembly outside the angle monitoring assembly, and a docking and stabilizing assembly within the accessory moving assembly. The pile driving equipment assembly includes a robotic arm, with a linkage plate rotatably connected to the lower end of the robotic arm. A sheet pile clamping head is mounted at the lower end of the linkage plate, and a sheet pile clamping head clamps a sheet pile strip at the lower end. Multiple sheet pile strips are horizontally interlocked and extend into the soil layer. The angle monitoring assembly includes an extension fixedly connected to the left side of the sheet pile clamping head. The lower end of extension rod one is fixedly connected to a fixed base, and the lower end of the fixed base is fixedly connected to an angle sensor one. The lower end of extension rod one is fitted with a movable locking plate seat that engages with the upper end of the previous sheet pile. The upper end of the movable locking plate seat is fixedly connected to an angle connector two. The lower end of angle connector two is slidably connected to a pair of limit clamps. The accessory moving component includes a motor fixedly connected to the lower end of the linkage plate. The output end of the motor is connected to the sheet pile clamping head. The right end of the sheet pile clamping head is fixedly connected to extension rod two. The lower ends of extension rod two are symmetrically fixedly connected to docking columns on the left and right sides.

[0008] In the aforementioned soft soil foundation pile foundation correction device, the pile driving equipment component in this solution precisely controls the driving of steel sheet piles, and the dual monitoring of the angle monitoring component provides reliable data to ensure the accuracy of verticality monitoring. When tilting is detected, the operator is promptly reminded to stop the machine for adjustment, which complies with safety regulations.

[0009] As a further improvement of this application, the movable locking plate base is symmetrically fixedly connected to the docking empty cylinders on the left and right sides, and the outer end of the docking column is provided with multiple annular grooves that are equidistantly arranged.

[0010] As a further improvement of this application, a miniature electric actuator is fixedly connected to the inner end of the groove, and an inner support bar is installed at the output end of the miniature electric actuator.

[0011] As a further improvement of this application, the outer end of the inner support strip is fixedly connected with an anti-slip outer layer, and the vertically corresponding docking column and docking empty cylinder are docked with each other.

[0012] As another improvement of this application, the docking stabilizing component includes an electrically strong magnetic block fixedly connected to the lower middle part of the movable locking plate base, and the electrically strong magnetic block is magnetically connected to the upper end of the steel sheet pile.

[0013] As a further improvement to this application, the lower end of the movable locking plate seat is symmetrically provided with strip grooves on both sides, and the two strip grooves and the corresponding limiting clamps are slidably connected.

[0014] As a further improvement to this application, a transverse spring is installed between the limiting clamp and the strip groove, and an arc-shaped insertion slope is provided on the lower side of the two limiting clamps at their close ends.

[0015] In summary, this solution utilizes piling equipment components to precisely control the driving of sheet piles, dual monitoring by angle monitoring components to provide reliable data and ensure accurate verticality monitoring. When tilting is detected, the system promptly alerts operators to stop and adjust, complying with safety regulations. Manual judgment prevents excessive automatic mechanical correction, adapting to the sudden shifting characteristics of soft soil foundations. Dynamic adjustment of accessory moving components ensures stable displacement, and secure docking components guarantee precise displacement. The overall solution achieves simultaneous piling and correction, improving piling efficiency and quality, ensuring the verticality of sheet piles, enhancing the stability and safety of soft soil foundation pile structures, reducing subsequent maintenance, and extending service life.

Detailed Implementation

[0018] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0019] First implementation method: Figures 1-6 This invention discloses a pile foundation correction device for soft soil foundations, comprising a pile driving equipment assembly 1, an angle monitoring assembly 2 disposed on the side of the pile driving equipment assembly 1, an accessory moving assembly 3 disposed outside the angle monitoring assembly 2, and a docking and stabilizing assembly 4 disposed within the accessory moving assembly 3. The pile driving equipment assembly 1 includes a robotic arm 100, a linkage plate 101 rotatably connected to the lower end of the robotic arm 100, a steel sheet pile clamping head 102 mounted on the lower end of the linkage plate 101, and a steel sheet pile strip 103 clamped at the lower end of the steel sheet pile clamping head 102. Multiple steel sheet pile strips 103 are horizontally inserted into each other and extend into the soil layer. The angle monitoring assembly 2 includes an extension rod 200 fixedly connected to the left side of the steel sheet pile clamping head 102, a fixing seat 201 fixedly connected to the lower end of the extension rod 200, and an angle sensor 202 fixedly connected to the lower end of the fixing seat 201. A BN model sensor can be selected. The C815 dual-axis tilt sensor has an extension rod 200 with a movable locking plate 203 that engages with the upper end of the previous sheet pile 103. An angle connector 205 is fixedly connected to the upper end of the movable locking plate 203. A BNC815-R data receiving module can be used, which supports RS485 communication. A pair of limit clamps 204 are slidably connected to the lower end of the angle connector 205 in conjunction with the angle sensor. The accessory moving component 3 includes a motor 300 fixedly connected to the lower end of the linkage plate 101. A Panasonic MSMD082G1U servo motor can be used. The output end of the motor 300 is connected to the sheet pile clamping head 102. An extension rod 201 is fixedly connected to the right end of the sheet pile clamping head 102. A docking column 302 is symmetrically fixedly connected to the lower left and right sides of the extension rod 201.

[0020] The movable locking plate base 203 is symmetrically fixedly connected to the docking empty cylinder 303 on both sides. The outer end of the docking column 302 is provided with multiple annular grooves 304 arranged at equal intervals. The inner end of the groove 304 is fixedly connected to a miniature electric actuator 305, which can be a TOLOMATICEA-05 miniature electric actuator. The output end of the miniature electric actuator 305 is equipped with an inner support strip 306. The outer end of the inner support strip 306 is fixedly connected to an anti-slip outer layer 307. The vertically corresponding docking column 302 and docking empty cylinder 303 are docked with each other.

[0021] Figures 1-6During pile driving operations, the pile driving equipment component 1, acting as the core actuator, adjusts the posture of the linkage plate 101 driven by the robotic arm 100. The sheet pile clamping head 102 clamps the sheet pile strips 103, pressing multiple horizontally interlocked sheet pile strips 103 into the soft soil layer segment by segment. An extension rod 200 fixed to the left side of the sheet pile clamping head 102 is equipped with an angle sensor 202 via a lower fixing seat 201 to collect the verticality data of the current sheet pile strip 103 in real time. Simultaneously, a movable locking plate seat 203, which engages with the upper end of the previous sheet pile strip 103, interacts with the angle sensor 202 via an upper angle connector 205 to provide a basis for correction. When the angle monitoring component 2 detects a tilt deviation in the sheet pile strip 103, it sends a signal to the operator's cabin connected to the robotic arm 100 to remind the operator to stop pile driving and adjust the pile verticality until both are restored. Once the machine returns to the normal range, it can continue to press down. When tilting is detected, a signal is sent to the cockpit to remind the operator to stop and adjust. This complies with the safety regulations for manual intervention. Especially in soft soil foundations, where sudden deviations are prone to occur, manual judgment can avoid over-adjustment problems that may occur when the machine is automatically corrected. When the next pile needs to be driven after this stage of pile driving is completed, the accessory moving component 3 starts dynamic adjustment. The motor 300 at the lower end of the linkage plate 101 drives the steel sheet pile clamping head 102 to rotate. At the same time, the docking column 302 at the lower end of the extension rod 2 301 is inserted into the docking empty cylinders 303 on both sides of the movable locking plate seat 203. The miniature electric push rod 305 in the groove 304 pushes the inner support strip 306 outward, so that the anti-slip outer layer 307 tightly abuts against the inner wall of the docking empty cylinder 303, lifts it up, and moves it above the next pile, ensuring that the steel sheet pile strip 103 remains vertical in the soft soil to complete the pile driving.

[0022] Second implementation method: Figure 4 , Figure 7 This invention discloses a pile foundation correction device for soft soil foundations. The docking stabilization component 4 includes an electrically strong magnetic block 403 fixedly connected to the lower middle part of a movable locking plate base 203. The electrically strong magnetic block 403 is magnetically connected to the upper end of a steel sheet pile strip 103. The lower ends of the movable locking plate base 203 are symmetrically provided with strip-shaped grooves 400. Two strip-shaped grooves 400 are slidably connected to corresponding limiting clamps 204. A transverse spring 401 is installed between the limiting clamps 204 and the strip-shaped grooves 400. The lower side of the end of the limiting clamp 204 that is close to each other has an arc-shaped easy-insertion inclined surface 402. The docking and stabilizing component 4 can facilitate the placement stability when the angle docking device 205 is moved. The electric strong magnetic block 403 at the lower end of the movable locking plate seat 203 is magnetically attracted to the upper end of the steel sheet pile strip 103. With the sliding connection between the strip groove 400 and the limiting clamp 204, the displacement accuracy of the movable locking plate seat 203 is guaranteed, and the steel sheet pile strip 103 is kept vertical in the soft soil to complete the piling.

[0023] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
