Description

Technical Field

[0001] The present invention relates to the technical field of foundation treatment, and in particular to a segmented foundation reinforcement device and method suitable for soft soil foundations. Background Art

[0002] In my country's coastal economically developed areas, soft soil foundations are widely distributed. Due to their various adverse engineering properties such as high porosity, high water content, high compressibility and low bearing capacity, they pose serious hazards to projects and need to be reinforced using soft soil foundation treatment methods.

[0003] Among all the soft soil foundation treatment methods, the drainage consolidation method is the most commonly used one, and among the traditional drainage consolidation methods, the most frequently used one is the plastic drain board foundation consolidation, that is, applying plastic drain boards on the soft soil layer, laying sand cushion layers on the soft soil surface, and applying loads on the sand cushion layers to perform drainage consolidation work on the soft soil foundation. Existing plastic drain boards are all pressed into the soil layer using high-strength stamping equipment. If there are hard materials in the foundation, it is easy to cause the hollow guide rod and the stamping head to break and damage, and it is impossible to achieve automatic connection and separation between the plastic drain board and the hollow guide rod; and when the existing plastic drain board construction equipment is under construction, there are also problems such as poor board insertion efficiency of the plastic drain board and the traditional board insertion equipment directly pulling the plastic drain board to be embedded, which is easy to cause scratches and damage to the surface of the plastic drain board.

[0004] The invention patent with the publication number CN113235554B discloses a soft soil foundation processing device, including a fixed frame, a mobile chassis and a cab, the mobile chassis is clamped at the bottom of the fixed frame, a winding vertical roller is installed on the top of the fixed frame, the outside of the winding vertical roller is rolled with a plastic drainage board, and a plug-in mechanism is arranged on one side of the outside of the fixed frame, the plug-in mechanism is used to continuously embed the plastic drainage board into the soft soil foundation for fixing, the plug-in mechanism includes a fixed support plate, a driving column, a hollow guide rod, an arc-shaped support slope, a fixed ring sleeve, an interlocking roller and a driving mechanism, so as to achieve a periodically stable and efficient plug-in. This patent solves the problem in the prior art that when high-strength stamping equipment is used to pre-press the drainage board, the presence of hard materials in the foundation easily causes the hollow guide rod and the punch head to break and be damaged, and the problem that the drainage board plug-in is inefficient and the surface is easily scratched and damaged. However, when the above-mentioned device is in use, only drainage boards can be used to treat the foundation. It is mainly used in the plastic drainage board combined with the loading method and the plastic drainage board combined with the vacuum preloading method, both of which belong to the drainage consolidation method. The drainage consolidation method alone has a poor reinforcement effect when reinforcing soft soil foundations, especially for soft soils with poor permeability. Drainage consolidation alone cannot achieve the desired effect.

[0005] In recent years, many new soft soil foundation treatment methods have been proposed, such as chemical reinforcement method, high vacuum compaction method, vacuum combined loading preloading method and electroosmotic consolidation method. Among them, the chemical reinforcement method is to use the curing agent to mix into the soft soil, and the curing agent interacts with the soft soil to reinforce the soft soil foundation; this method improves the physical and mechanical properties of the soft soil, can effectively improve the strength of the soft soil foundation, and the treated soil has the advantages of high strength and low permeability. It is widely used in national highways, airports, seawalls, ports, docks, water conservancy anti-seepage and other engineering projects; if the chemical reinforcement method can be combined with drainage reinforcement, the foundation reinforcement effect can be greatly increased. The existing technology cannot achieve the above purpose. In addition, the existing curing agent is transported to the mixing head at the front end of the excavator through a hose. The driver controls the excavator to make the mixing head go deep into the soft soil. While the mixing head rotates, the curing agent and the soft soil are fully mixed to achieve the expected curing effect. The existing curing agent addition method can only add the curing agent to the soft soil layer at the same depth, and cannot meet the curing agent addition of different soft soil layers.

[0006] Therefore, it is necessary to provide a soft soil reinforcement treatment device that can simultaneously treat the soft soil foundation through a plastic drainage board and a stabilizer, and can add a curing agent in sections and layers. Summary of the invention

The driving mechanism 8 adopts a driving motor. The first bracket 1 and the second bracket 7 are used to support the device as a whole. A first transmission mechanism, a second transmission mechanism, a plug-in mechanism and a stabilizer extrusion mechanism 16 are set between the first bracket 1 and the second bracket 7. The plug-in mechanism includes a stopper 20 with a pointed bottom and two groups of drain board conveying mechanisms. A plastic drain board 18 is provided between the two groups of drain board conveying mechanisms. The front side of the stopper 20 is hinged to one group of the drain board conveying mechanisms, and the rear side is movably connected to the other group of the drain board conveying mechanisms. The bottom end of the plastic drain board 18 is located on the stopper 20; the driving mechanism 8 is transmission-connected to the two groups of drain board conveying mechanisms through the first transmission mechanism, and is used to control the insertion of the plastic drain board 18. A tube body 19 for storing stabilizer is installed on both sides of the plastic drain board 18. The tube body 19 is a square tube structure with a width matching that of the plastic drain board 18. A sealing plate 28 is provided at the bottom. The lower surface of the sealing plate 28 is flush with the lower surface of the plastic drain board 18. A plurality of discharge holes 22 are opened in the middle and lower part of the tube body 19. A rubber block 23 is installed on the discharge hole 22. A cross slit is provided in the middle of the rubber block 23. The discharge holes 22 are evenly distributed on the tube body 19. The rubber blocks 23 on the discharge holes 22 can spray stabilizer through the cross slit, so that the stabilizer can penetrate into the soft soil layer more efficiently, thereby enhancing the soft soil treatment effect of the device. Support components are provided on the tube bodies 19 on both sides. The stabilizer extrusion mechanism 16 includes a connecting cross bar 1601, two transmission plates 1602 and two pressure rods 1605 fixed at both ends of the connecting cross bar 1601 and matching with the tube body 19, and a pressure block 1604 is fixedly connected to the bottom of each pressure rod 1605, the second transmission mechanism is transmission-connected to the first transmission mechanism, the first transmission mechanism is transmission-connected to the two transmission plates 1602, and the two transmission plates 1602 are respectively connected to the connecting cross bar 1601 through fixed blocks 1603. When the two groups of drain board conveying mechanisms convey the plastic drain boards 18 downward, the stabilizer extrusion mechanism presses down to press the two pressure rods 1605 into the tube bodies 19 on both sides of the plastic drain boards 18, and the pressure blocks 1604 contact the inner wall of the tube body 19 and slide downward to squeeze the stabilizer in the tube body from the position of the discharge hole 22, so that the stabilizer reacts with the water in the soft soil layer to consolidate the soil, thereby achieving the purpose of adding stabilizer to the soil while inserting the drain boards.

[0046] The first embodiment provides a segmented foundation treatment device suitable for soft soil foundation, such as Figures 1 to 13As shown, the first transmission mechanism is provided with two groups, which are symmetrically arranged on the top of the two groups of drainage board conveying mechanisms. Each group of the first transmission mechanism includes a transmission gear 9 and a transmission shaft 11. The transmission shaft 11 is rotatably installed between the first bracket 1 and the second bracket 7. The transmission gear 9 is fixedly installed at the end of the transmission shaft 11, and the transmission gears 9 of the two groups of first transmission mechanisms are meshed with each other. The driving mechanism 8 is installed at the end of one of the groups of the first transmission mechanisms, and its output shaft is fixedly connected to the end of the group of transmission shaft 11; the two groups of first transmission mechanisms are simultaneously controlled to rotate by the driving mechanism 8. Each set of drainage board conveying mechanism includes a first transmission wheel 4, a second transmission wheel 5 and a clamping plate 15, wherein the first transmission wheel 4 and the second transmission wheel 5 are fixed on the transmission shaft 11 of the corresponding first transmission mechanism, the two sets of clamping plates 15 are located between the two sets of first transmission mechanisms, and clamp the plastic drainage board 18, each set of clamping plates 15 extends vertically downward along the plastic drainage board 18, and two transmission racks 10 respectively matching the first transmission wheel 4 and the second transmission wheel 5 are provided on each set of clamping plates 15, and the first transmission wheel 4 and the second transmission wheel 5 of each set of drainage board conveying mechanism are located on the outer surface of the corresponding clamping plate 15, and are connected to the corresponding transmission rack 10. A slide groove 12 is vertically provided in the middle of each set of clamping plates 15, and two sets of transmission racks are symmetrically distributed on both sides of the slide groove 12, and two transmission plates 1602 are respectively slidably embedded in the two slide grooves 12 and move up and down along the slide groove 12. The stopper 20 is located at the bottom of the two groups of clamping plates 15 , wherein the bottom of the front clamping plate 15 is rotatably connected to the stopper 20 via a rotating shaft, and a magnetic block 21 is provided at the bottom of the rear clamping plate 15 . The stopper 20 is made of magnetic metal and can be adsorbed by the magnetic block 21 . A plurality of pressing plates 1501 are provided on the top of the two groups of clamping plates 15 adjacent to the side of the plastic drain plate 18, and the plastic drain plate 18 is squeezed by the pressing plates 1501. The bottom of the rear clamping plate 15 is fitted with each other through the magnetic block 21 and the stopper 20. The front clamping plate 15 and the stopper 20 are rotatably connected. The magnetic block 21 can adsorb the stopper 20 so that the stopper 20 keeps the tip facing downward. At the same time, the adsorption and fitting of the magnetic block 21 and the stopper 20 facilitates the subsequent removal of the clamping plate 15 as a whole from the device. When the two groups of first transmission wheels 4 and second transmission wheels 5 rotate in opposite directions, they can abut against the corresponding transmission rack 10, driving the two groups of clamping plates 15 to move downward, thereby driving the plastic drain plate 18 to move downward as a whole. A first limiting plate 2 and a second limiting plate 3 are respectively provided on the side adjacent to the end of the transmission shaft of the first transmission wheel 4 and the second transmission wheel 5. The first limiting plate 2 and the second limiting plate 3 are used to limit the left and right sides of the clamping plate 15 to ensure that the clamping plate 15 moves vertically downward.

[0047] The first embodiment provides a segmented foundation treatment device suitable for soft soil foundation, such as Figures 1 to 13As shown, the second transmission mechanism includes two third transmission wheels 6 fixed on two transmission shafts 11, the third transmission wheels 6 are located between the first transmission wheel 4 and the second transmission wheel 5, and the two third transmission wheels 6 are respectively connected to the two transmission plates 1602. The transmission plate 1602 can adopt a rack structure, or the surface of the plate body is provided with a transverse convex pattern, which can be connected to the third transmission wheel 6. The third transmission wheel 6 is an eccentric wheel. When the third transmission wheel 6 performs eccentric circular motion, it will intermittently abut against the transmission plate 1602, so that the transmission plate 1602 intermittently slides downward, and the two groups of pressure rods 1605 and the pressure block 1604 connecting the left and right sides of the cross bar 1601 will intermittently move downward, and the pressure block 1604 can intermittently squeeze the stabilizer from the device later, so that each section of the soft soil layer can be squeezed into the stabilizer. The third transmission wheel 6 is connected to the transmission shaft 11 through a rubber plate connection structure. The third transmission wheel 6 is a hollow wheel body. The rubber plate connection structure includes a plurality of first rubber plates 13 fixed in the inner cavity of the third transmission wheel 6 and a plurality of second rubber plates 14 correspondingly fixed on the transmission shaft 11. A groove matching the second rubber plate 14 is opened at one end of the first rubber plate 13 adjacent to the transmission shaft 11. The plurality of second rubber plates 14 on the transmission shaft 11 are correspondingly embedded in the grooves on the plurality of first rubber plates 13 on the third transmission wheel 6. In the embodiment, the first rubber plates 13 and the second rubber plates 14 fit each other. The central axis of the third transmission wheel 6 is not on the same straight line as the central axis of the transmission shaft 11. The diameter of the third transmission wheel 6 is greater than that of the first transmission wheel 4 and the second transmission wheel 5. The first transmission wheel 4 and the second transmission wheel 5 are smaller in size, which is convenient for intermittent extrusion of the stabilizer in the subsequent process of the drainage plate moving downward. The first rubber plates 13 and the second rubber plates 14 that fit each other can slide or bend relative to each other, so that the third transmission wheel 6 can perform eccentric circular motion. When the two transmission shafts 11 rotate, the first rubber plate 13 and the second rubber plate 14 are intermittently bent or slide relative to each other, so that the third transmission wheel 6 can perform eccentric circular motion when rotating. Since the diameter of the third transmission wheel 6 is larger than the diameter of the first transmission wheel 4 and the second transmission wheel 5, the depth of the transmission plate 1602 moving downward when the third transmission wheel 6 abuts against the transmission plate 1602 will be greater than the depth of the first transmission wheel 4, the second transmission wheel 5 and the clamping plate 15 moving downward in the same time, so that the pressure rod 1605 and the pressure block 1604 on the left and right sides of the connecting cross bar 1601 move downward relative to the tube body 19, thereby squeezing the stabilizer in the tube body 19, so that the stabilizer is uniformly squeezed out from the multiple discharge holes 22 through the cross slits on the rubber block 23, and as the clamping plate 15 continues to move downward, and the transmission plate 1602 moves downward intermittently relative to the clamping plate 15, each height layer of the soft soil foundation can be uniformly squeezed into the stabilizer, thereby realizing the function of segmented consolidation of the soil.

[0048] The transmission gear 9 is driven by the motor 8 to rotate, which drives the other group of transmission gears to rotate in the opposite direction, so that the two groups of transmission shafts 11 keep rotating in the opposite direction. Subsequently, the two groups of first transmission wheels 4 and second transmission wheels 5 at the front and rear of the device can be in contact with the clamping plate 15 to drive the clamping plate 15 to move continuously downward. The eccentric structure composed of the third transmission wheel 6 and the transmission shaft 11 makes the third transmission wheel 6 intermittently drive the stabilizer extrusion mechanism 16 to move downward during rotation, so as to intermittently squeeze the internal cavity of the tube body 19 subsequently. A plastic drain plate 18 is arranged between the two groups of clamping plates 15 and the stabilizer extrusion mechanism 16. The tube body 19 is installed on the left and right sides of the plastic drain plate 18. A plurality of support assemblies 24 are installed on the tube body 19. A plurality of vertical slots are evenly and equidistantly provided on the front and rear sides of the tube body 19, and each group of support assemblies 24 is correspondingly installed in each vertical slot.

[0049] In the embodiment, the support assembly 24 includes a rotating plate 2401 rotatably installed in the vertical slot, and the lower end of the rotating plate 2401 is rotatably connected to the side wall of the tube body 19, and a torsion spring 2403 is fixedly connected between the rotating plate 2401 and the tube body 19, and under the action of the torsion spring 2403, the rotating plate 2401 is located in the vertical slot and blocks the vertical slot; a protrusion 2402 is provided on the outer side of the upper end of the rotating plate 2401, and the protrusion 2402 extends out of the vertical slot. The rotating plate 2401 always tends to rotate outward under the action of the torsion spring 2403. When the tube body 19 moves downward, the soil provides an upward resistance, which causes the rotating plate 2401 to close and be placed in the vertical slot. After the tube body 19 is completely inserted into the soil layer, the torsion spring 2403 on the rotating plate 2401 causes the rotating plate 2401 to unfold, so that the rotating plate 2401 can be embedded in the soil layer after unfolding, making it difficult for the tube body 19 to be removed from the soft soil foundation, thereby ensuring the operation of the device.

[0050] like Fig.13 As shown, the top of the plastic drain plate 18 is connected with a guide pipe 25, a connecting rod 26 is fixedly arranged between two adjacent guide pipes 25, and a guide plate 27 is fixedly connected to the bottom of the connecting rod 26. By adding a stabilizer into the tube body 19, when the internal cavity of the tube body 19 is intermittently squeezed by the stabilizer squeezing mechanism 16, the stabilizer in the tube body 19 can be intermittently squeezed into the soft soil foundation to achieve the soil consolidation function. At the same time, the clamping plate 15 moves the plastic drain plate 18 into the soft soil foundation, and the water discharged from the two groups of plastic drain plates 18 can be diverted to the guide plate 27 for centralized collection through the guide pipe 25.

[0051] Embodiment 1 proposes a segmented foundation treatment device suitable for soft soil foundation, such as Figure 1 and Figure 3As shown, a plurality of stabilizing blocks 17 are fixedly connected to the bottom of the first bracket 1 and the second bracket 7. The plurality of stabilizing blocks 17 are evenly dispersed on the bottom surfaces of the first bracket 1 and the second bracket 7. The cross-sectional area of ​​each stabilizing block 17 decreases from top to bottom to form an inverted cone or an inverted quadrangular pyramid. The stabilizing blocks 17 can ensure that the first bracket 1 and the second bracket 7 are stably placed on the foundation surface, thereby enhancing the overall stability of the device.

[0052] The working process of the segmented foundation treatment device suitable for soft soil foundation in the first embodiment is as follows: First, Figure 1-Figure 6 As shown, the plastic drain board 18 between the first bracket 1 and the second bracket 7 is vertically placed on the soft soil foundation surface, a stabilizer is added into the tube body 19, and then the stabilizer extrusion mechanism is moved to the upper position of the clamping plate 15, and then the driving mechanism 8 drives the transmission gear 9 and the transmission shaft 11 on one side to rotate, driving the transmission gear and the transmission shaft 11 on the other side of the plastic drain board 18 to rotate in the opposite direction; at this time, the first transmission wheel 4 and the second transmission wheel 5 of the device rotate in opposite directions, and the first transmission wheel 4 and the second transmission wheel 5 are connected to the transmission rack 10 on the clamping plate 15, so that The clamping plate 15 is driven to move downward, and the pressure plates 1501 on the clamping plates 15 on the front and rear sides of the device press against the plastic drain board 18, and drive the plastic drain board 18 to move downward as a whole. The sealing plate 28 can prevent debris from entering the tube body 19, and the magnetic block 21 can absorb the block 20 made of magnetic metal material, so that the block 20 keeps the tip facing downward and fits with the bottom of the plastic drain board 18 to avoid clogging of the bottom of the plastic drain board 18, and at the same time, the device can easily press the block 20 downward, and the magnetic block 21 is absorbed by the block 20, so that the clamping plate 15 can be moved out from the front and rear sides of the plastic drain board 18 as a whole later.

[0053] like Figure 4 and Figure 8-Figure 15 As shown, after the arrangement of the plastic drain board 18 is completed, the clamping plate 15 and the stabilizer squeezing mechanism 16 are taken out, and the front clamping plate 15 can pull the block 20 so that the block 20 is separated from the magnetic block 21. When the clamping plate 15 and the stabilizer squeezing mechanism 16 move upward, the tube body 19 will be driven upward. During the upward movement of the tube body 19, the protrusion 2402 is subjected to upward resistance, which will drive the rotating plate 2401 to rotate and expand so that it can be embedded in the soil layer. The tube body 19 and the plastic drain board 18 are not easily removed from the soft soil foundation, thereby keeping the plastic drain board 18 and the tube body 19 in the soft soil. By bonding the guide pipe 25, the connecting rod 26 and the guide plate 27 on the top of the two groups of plastic drain boards 18, the water in the soft soil is discharged to the guide plate 27 for collection.

[0054] Embodiment 2 provides a segmented foundation treatment method applicable to a soft soil foundation, using the segmented foundation treatment device applicable to a soft soil foundation described in Embodiment 1, specifically comprising the following steps:

[0055] S1: The plastic drain board 18 between the first bracket 1 and the second bracket 7 is vertically placed on the surface of the soft soil foundation. The stabilizing block 17 can be inserted into the soft soil for stabilization to prevent the device from sinking. A stabilizer is added into the tube body 19, and then the stabilizer extrusion mechanism 16 is moved to the upper position of the clamping plate 15. Then, one set of transmission gears 9 and the transmission shaft 11 are driven to rotate by the driving mechanism 8; the two transmission gears 9 are meshed with each other, thereby driving the transmission gear 9 and the transmission shaft 11 on the other side of the plastic drain board 18 to rotate in the opposite direction; the two transmission shafts 11 rotate, and the first transmission wheel 4 and the second transmission wheel 5 on the transmission shaft 11 rotate along the transmission shaft, and the third transmission wheel 6 performs eccentric movement along the transmission shaft 11;

[0056] S2: The first transmission wheels 4 and the second transmission wheels 5 on the two transmission shafts 11 are in frictional contact with the transmission racks 10 on the two clamping plates 15, respectively, so that the two sets of clamping plates 15 continue to move downward, and move the plastic drainage plates 18 downward and insert them into the soft soil layer; the third transmission wheels 6 on the two transmission shafts 11 are in frictional contact with the two transmission plates 1602, respectively, and the two transmission plates 1602 intermittently move downward under the action of the eccentric structure of the third transmission wheels 6, thereby driving the pressure rods 1605 and the pressure blocks 1604 on both sides to move downward intermittently;

[0057] S3: Since the initial position of the clamping plate 15 is located below the transmission plate 1602, when the clamping plate 15 drives the drainage plate to move to the soft soil layer, the pressure rod 1605 and the pressure block 1604 can squeeze the internal cavity of the tube body 19 during the intermittent downward movement, so that the stabilizer in the tube body 19 seeps out from the discharge hole 22, reacts with the water in the soft soil, and consolidates the soil;

[0058] S4: After the clamping plate 15 moves to the bottom, the clamping plate 15 on the side that is rotatably connected to the stopper 20 is pulled, so that the clamping plate 15 on the other side can be separated from the stopper 20; then, the driving mechanism 8 is rotated in the opposite direction or the two groups of clamping plates 15 and the two groups of transmission plates 1602 are directly pulled out, and the clamping plates 15 and the transmission plates 1602 will slide upward on the plastic drain plate 18. During the upward movement of the clamping plates 15 and the transmission plates 1602, the tube body 19 is driven upward. When the tube body 19 moves upward, the protrusion 2402 is subjected to upward resistance, and it will drive the rotating plate 2401 to rotate and expand and embed into the soil layer. The tube body 19 and the plastic drain plate 18 are not easily removed from the soft soil foundation, thereby keeping the plastic drain plate 18 and the tube body 19 in the soft soil;

[0059] S5. After the plastic drain plates 18 are installed, the water in the soft soil is discharged to the guide plates 27 for collection by bonding the guide pipes 25, the connecting rods 26 and the guide plates 27 on the tops of two adjacent sets of plastic drain plates 18.

[0060] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
