Description

Technical Field

[0001] The present invention relates to the technical field of foundation reinforcement devices, and in particular to a foundation reinforcement device and a reinforcement method thereof. Background Art

[0002] Foundation reinforcement devices refer to equipment used to increase soil bearing capacity and improve foundation stability. In construction projects, foundation reinforcement is particularly important, especially when the geological conditions are poor or when large structures such as high-rise buildings, bridges, and roads need to be built. The following are some foundation reinforcement methods and their corresponding devices:

[0003] Pile foundation: Precast piles, which are prefabricated concrete piles or steel piles, are driven into pre-dug pits by pile drivers; Cast-in-place piles, which are formed by pouring concrete after drilling holes on site; Screw piles, which are steel pipe piles with spiral blades, are driven to a predetermined depth by rotation;

[0004] Soil solidification: Cement mixing piles use cement as a curing agent, which is mixed with soil and hardened to form a column with a certain strength; chemical grouting, injecting chemical solutions into the soil layer to make it penetrate and react with soil particles to increase the density and strength of the soil.

[0005] Most of the existing precast piles only rely on the force at the bottom of the pile to provide support, but the support relying solely on the bottom cannot meet the support force required by the precast piles in some areas with poor geological conditions. In addition, the side walls of the precast piles are relatively smooth and cannot provide additional support for the precast piles, which will result in poor reinforcement effect of the precast piles on the foundation. Summary of the invention

[0033] S5: When the push rod moves to the limit distance, the liquid pressure in the installation shell continues to increase, so that the adjustment tube continues to move despite the resistance of the limit column. The adjustment tube moves, and when the second through hole on the adjustment tube is aligned with the next first through hole, water flows into the next installation shell. The above process is repeated. After all the sliding parts are extended, cement is injected into the pit and the device for reinforcement. At this point, the installation is completed.

[0034] The present invention has the following advantages: the present invention drives a plurality of sliding parts to move by hydraulic pressure, and the sliding parts drive adjacent breaking heads to move, and the breaking heads break the soil and insert into the soil, thereby providing vertical support for the device to improve the supporting capacity of the device, thereby improving the stability of the foundation and preventing the foundation from continuing to sink.

[0035] When the soil breaking head encounters a stone, the soil breaking head is rotated so that the soil breaking head continues to move close to the upper side of the stone, and the stability of the device is improved by the support of the stone.

[0036] A plurality of push rods are driven by hydraulic pressure to push adjacent extrusion bars to move respectively, so that the extrusion bars are embedded in the soil, thereby further increasing the supported points of the device, thereby further improving the stability of the device.

DETAILED DESCRIPTION

[0048] The embodiments of the present application will be described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and should not be construed as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

[0049] A foundation reinforcement device and a reinforcement method thereof, such as Figure 1-Figure 10 As shown, it includes: an outer shell 1; a plurality of mounting shells 2, all of which are rotatably connected to the outer shell 1, the mounting shell 2 is provided with a first slide groove 201, the mounting shell 2 is slidably connected to a sliding member 3, the sliding member 3 slides in the adjacent first slide groove 201, and the sliding member 3 is fixedly connected to a mounting rod 4; a breaking head 5, the number of which is consistent with the number of the mounting shells 2, and the plurality of breaking heads 5 are rotatably connected to adjacent mounting rods 4.

[0050] In the above scheme, it is intended to provide more support points for the device to improve the stability of the device. The outer shell 1 is made of metal, which provides higher strength for the device. Several threaded rods are arranged on the upper side of the outer shell 1 to connect with the foundation. There are five mounting shells 2 in the figure. The direction of each mounting shell 2 is different and there is no regularity. When the soil-breaking head 5 is inserted into the soil, a cavity is generated in the part it passes through, and the soil above the cavity falls. Through the irregular arrangement of the mounting shell 2, the remaining soil-breaking heads 5 on the upper side will not be located directly above the cavity, thereby reducing the impact of the cavity and improving the stability of the device. The soil-breaking head 5 is in the shape of an arrow, thereby reducing the resistance of the soil-breaking head 5 when it moves in the soil.

[0051] Furthermore, it also includes: an adjusting shell 6, which is fixedly connected to the outer shell 1, the adjusting shell 6 is provided with a plurality of first through holes, a plurality of mounting shells 2 are respectively connected with the corresponding first through holes on the adjusting shell 6, and the adjusting shell 6 is connected with the water supply device; an adjusting cylinder 7, which is slidably connected to the adjusting shell 6, the adjusting cylinder 7 is provided with a second through hole, the adjusting cylinder 7 is sealed with the first through hole, the adjusting cylinder 7 is slidably connected with a limiting column 8, a first spring is provided between the limiting column 8 and the adjusting cylinder 7, and the adjusting shell 6 is provided with a plurality of grooves, and the limiting column 8 is limitedly matched with adjacent grooves.

[0052] In the above scheme, the aim is to automatically switch the installation shell 2 during injection. The lower side of the regulating shell 6 is provided with through holes in the same number as the number of the installation shells 2. Each installation shell 2 is connected to the corresponding first through hole on the regulating shell 6 through a pipeline. One side of the regulating shell 6 is connected with a pipeline, which penetrates the upper side of the outer shell 1, so that the water supply device injects water into the regulating shell 6. The water supply device is an existing device and will not be described in detail here. A small hole is opened on the other side of the regulating shell 6, which is connected to the outside world, so that when the regulating cylinder 7 moves, no additional resistance will be generated due to the increase in air pressure. When water is injected into the regulating shell 6, the water pressure acts on the regulating cylinder 7, thereby pushing the regulating cylinder 7 to move, so as to change the installation shell 2 connected to the regulating cylinder 7. The limit column 8 is composed of a hemisphere and a cylinder. The first spring is initially in a compressed state, so that the earth-breaking head 5 moves to the farthest distance before the regulating cylinder 7 moves.

[0053] Working process: When using the device to reinforce the foundation, after selecting the installation site, dig a deep pit with suitable diameter and depth from the site, then place the device in the pit and tamp it to prevent the bottom of the pit from sinking, and then inject water into the regulating shell 6 through the water supply device. After the water flows in, it passes through the second through hole of the regulating cylinder 7 and the first through hole of the regulating shell 6 and enters the corresponding mounting shell 2. The liquid in the mounting shell 2 increases and pushes the sliding member 3 to move, and the sliding member 3 drives the mounting rod 4 to move, and the mounting rod 4 drives the breaking head 5 to move, and the breaking head 5 is inserted into the soil. When the breaking head 5 moves to the limit position, the water pressure in the regulating shell 6 gradually increases. When it reaches a certain value, The adjusting cylinder 7 moves, and the adjusting cylinder 7 drives the limiting column 8 to move. When the limiting column 8 moves, it is squeezed by the adjusting shell 6, and the limiting column 8 compresses the first spring. When the second through hole on the adjusting cylinder 7 is aligned with the next first through hole on the adjusting shell 6, the water flows into the next installation shell 2. At this time, the water pressure drops, and the limiting column 8 is inserted into the adjacent groove under the action of the first spring. At this time, the corresponding breaking head 5 moves, and the above process is repeated. When the last breaking head 5 is inserted into the figure, the installation of the device is completed, and concrete can be injected into the outer shell 1 to further improve the structural strength of the device. Finally, the foundation is fixed to the upper side of the device to complete the reinforcement of the foundation.

[0054] Furthermore, it also includes: a rotating shell 9, the number of which is consistent with the number of the mounting shells 2, and the rotating shell 9 is hinged to the adjacent mounting rod 4; a sliding rod 10, the number of which is consistent with the number of the mounting shells 2, the sliding rod 10 is slidably connected to the adjacent rotating shell 9, the sliding rod 10 is hinged to the adjacent breaking head 5, the sliding rod 10 is slidably connected to a first limit block 11, a second spring is arranged between the first limit block 11 and the adjacent sliding rod 10, and the rotating shell 9 is provided with a plurality of first limit grooves, and the first limit block 11 is limitedly matched with the adjacent first limit grooves.

[0055] In the above scheme, the purpose is to make the earth-breaking head 5 avoid stones during the movement so that the earth-breaking head 5 can reach the farthest moving distance. The rotating shell 9 is located below the hinge of the mounting rod 4 and the earth-breaking head 5, so that when the sliding rod 10 moves out of the rotating shell 9, the earth-breaking head 5 rotates upward, and then when the earth-breaking head 5 is blocked by stones, it passes through the upper side of the stones, and with the support of the stones, the stability of the device itself is enhanced. The first limit block 11 is provided with an inclined surface. When the sliding rod 10 moves out of the rotating shell 9, it drives the first limit block 11 to move. The first limit groove squeezes the inclined surface of the first limit block 11 to move the first limit block 11. When the sliding rod 10 moves into the rotating shell 9, the first limit block 11 is blocked by the first limit groove and cannot move, so that the earth-breaking head 5 is locked after rotating and will not rotate again, so as to ensure the stability of the device.

[0056] Further, it also includes: a second limit block 12, the number of which is consistent with the number of the mounting shells 2, the mounting shell 2 is provided with a second slide groove 202, the second limit block 12 is slidably connected in the adjacent second slide groove 202, a third spring is provided between the second limit block 12 and the adjacent mounting shell 2, the second limit block 12 is provided with a connecting groove 1201, the rotating shell 9 is connected to the adjacent second slide groove 202 through a pipeline, the mounting shell 2 is provided with a first communicating groove 203, the first communicating groove 203 is connected to the adjacent first slide groove 201, the first communicating groove 203 is connected to the adjacent second slide groove 202 through a pipeline, the second limit block 12 is matched with two adjacent pipeline blockages, the sliding member 3 is provided with a round rod portion and a round pier portion, the round pier portion of the sliding member 3 is slidably connected to the mounting shell 2, the round pier portion of the sliding member 3 is provided with a second limit groove that is limited and matched with the adjacent second limit block 12, the round rod portion of the sliding member 3 is provided with a plurality of third limit grooves, and the second limit block 12 is limited and matched with the adjacent third limit groove.

[0057] In the above scheme, the purpose is to rotate the earth-breaking head 5 when the sliding member 3 cannot move further, so that the earth-breaking head 5 avoids the obstruction and the sliding member 3 continues to extend to the maximum extent. The connecting groove 1201 is a quadrangular prism, and the height of the connecting groove 1201 is greater than the depth of the third limiting groove on the sliding member 3, so that when the third limiting groove squeezes the second limiting block 12 to move, the two pipes adjacent to the second limiting block 12 are connected through the connecting groove 1201. When the round pier portion of the sliding member 3 squeezes the second limiting block 12 to move and the second limiting block 12 is inserted into the second limiting groove, the connecting groove 1201 is misaligned with the two pipes, and the second limiting block 12 blocks the two pipes.

[0058] Furthermore, it also includes: a blocking column 13, the mounting shell 2 is provided with a third slide groove 204, the blocking column 13 is slidably connected to the third slide groove 204, a fourth spring is provided between the blocking column 13 and the adjacent mounting shell 2, the blocking column 13 is blocked and cooperated with the adjacent first connecting groove 203, the third slide groove 204 is connected with the adjacent first connecting groove 203, the mounting shell 2 is provided with a second connecting groove 205, and the second connecting groove 205 connects the adjacent third slide groove 204 with the adjacent first slide groove 201.

[0059] In the above scheme, the blocking column 13 is intended to release the blocking of the adjacent first connecting groove 203 when the earth-breaking head 5 is blocked. The blocking column 13 is used to block the first connecting groove 203. When the earth-breaking head 5 is not blocked, the earth-breaking head 5 continues to move in the horizontal direction, so that the sliding member 3 is extended to the longest in the horizontal state, and the fourth spring is initially in a compressed state, thereby preventing the water pressure from directly pushing the blocking column 13 to move.

[0060] Working process: when water is injected into the installation shell 2, the water in the installation shell 2 pushes the sliding member 3 to move, and the sliding member 3 drives the earth-breaking head 5 to move. When the earth-breaking head 5 is blocked by stones, the water pressure in the installation shell 2 continues to increase. At this time, the water pressure in the installation shell 2 transmits the pressure to the blocking column 13 through the second connecting groove 205, thereby pushing the blocking column 13 to move. The blocking column 13 moves and compresses the fourth spring, and the blocking column 13 releases the blockage of the first connecting groove 203, so that the water flows from the first connecting groove 203 through the pipeline into the connecting groove 1201, and then enters the rotating shell 9 through the pipeline. The increased liquid in the rotating shell 9 pushes the sliding rod 10 to move, thereby causing the earth-breaking head 5 to deflect upward. When the moving direction of the earth-breaking head 5 is offset from the stone, the resistance of the sliding member 3 to the movement of the earth-breaking head 5 is reduced. At this time, the blocking column 13 is reset under the action of the fourth spring, so that the earth-breaking head 5 stops rotating. The sliding member 3 continues to drive the earth-breaking head 5 to move until it is extended to the longest state. The round mound part of the sliding member 3 squeezes the second limit block 12, so that the second limit block 12 limits the sliding member 3.

[0061] Furthermore, it also includes: extrusion bars 14, which have a plurality of them and are fixed between adjacent mounting rods 4 and adjacent breaking heads 5; fixed shells 15, which have a plurality of them and are respectively fixed to adjacent mounting rods 4, the fixed shells 15 are slidably connected to the pushing rods 16 fixed to the adjacent extrusion bars 14, the fixed shells 15 are connected to the adjacent first slide grooves 201 through pipelines, and also include: third limit blocks 17, the number of which is the same as the number of the pushing rods 16, the third limit blocks 17 are slidably connected to the adjacent pushing rods 16, a fourth spring is arranged between the third limit blocks 17 and the adjacent pushing rods 16, and the fixed shell 15 is provided with a plurality of fifth limit grooves that cooperate with the adjacent third limit blocks 17.

[0062] In the above scheme, the purpose is to improve the support of the device in the soil and prevent the device from sinking in the soil. The two adjacent extrusion bars 14 in the figure are symmetrically distributed, and the back sides of the two adjacent extrusion bars 14 are thin and the facing sides are thick, so that the extrusion bars 14 are easier to insert into the soil. The extrusion bars 14 have high flexibility in the horizontal direction and high hardness in the vertical direction, so that the extrusion bars 14 can be smoothly inserted into the soil and can withstand the force in the vertical direction. The resistance of the fifth limit groove to the third limit block 17 is greater than the resistance encountered by the soil-breaking head 5 when it moves, so that when the soil-breaking head 5 is extended to the longest state, the push rod 16 is moved.

[0063] Working process: when the breaking head 5 is extended to the longest state, the liquid pressure in the mounting shell 2 increases, and the liquid in the mounting shell 2 enters the fixed shell 15. The increase in liquid in the fixed shell 15 pushes the push rod 16 to move, and the push rod 16 drives the third limit block 17 to move. When the third limit block 17 moves, it is squeezed by the fifth limit groove, and the third limit block 17 compresses the fourth spring. The third limit block 17 pushes the extrusion strip 14 to deform, and the middle part of the extrusion strip 14 moves outward. When the push rod 16 moves to the limit distance, the third limit block 17 is inserted into the fifth limit groove under the action of the fourth spring, thereby preventing the third limit block 17 from moving in the opposite direction. At this time, the liquid pressure in the mounting shell 2 continues to increase, so that the adjusting cylinder 7 overcomes the resistance of the limit column 8 and continues to move.

[0064] A reinforcement method for a foundation reinforcement device can be applied to a foundation reinforcement device, and the reinforcement method of the device comprises the following steps:

[0065] S1: First, select the installation site and dig a deep pit, then place the device in the pit and tamp it, then place the device in the pit, then inject water into the regulating shell 6, the water flows into the installation shell 2, the liquid in the installation shell 2 increases and pushes the sliding member 3 to move, and the sliding member 3 drives the earth-breaking head 5 to move;

[0066] S2: When the earth-breaking head 5 is blocked by a stone, the blocking column 13 moves and compresses the fourth spring, and the blocking column 13 releases the blockage of the first connecting groove 203, allowing water to flow into the rotating shell 9. The liquid in the rotating shell 9 increases and pushes the sliding rod 10 to move, thereby causing the earth-breaking head 5 to deflect upward;

[0067] S3: When the moving direction of the earth-breaking head 5 is offset from the stone, the blocking column 13 is reset under the action of the fourth spring, so that the earth-breaking head 5 stops rotating, and the sliding member 3 continues to drive the earth-breaking head 5 to move until it reaches the longest state;

[0068] S4: When the earth-breaking head 5 is extended to the longest state, the liquid pressure in the mounting shell 2 increases and pushes the push rod 16 to move, the push rod 16 drives the extrusion strip 14 to deform, and the middle part of the extrusion strip 14 moves outward;

[0069] S5: When the push rod 16 moves to the limit distance, the liquid pressure in the installation shell 2 continues to increase, so that the adjustment cylinder 7 overcomes the resistance of the limit column 8 and continues to move. The adjustment cylinder 7 moves. When the second through hole on the adjustment cylinder 7 is aligned with the next first through hole, the water flows into the next installation shell 2. The above process is repeated. After all the sliding parts 3 are extended, cement is injected into the pit and the device for reinforcement. At this point, the installation is completed.

8. A method for reinforcing a foundation reinforcement device, characterized in that: According to the foundation reinforcement device of claim 7, the specific method of use is as follows: S1: First, the installation site is selected and a deep pit is dug. Then, the device is placed in the pit and compacted. Then, water is injected into the regulating shell (6). The water flows into the installation shell (2). The liquid in the installation shell (2) increases and pushes the sliding member (3) to move. The sliding member (3) drives the earth-breaking head (5) to move. S2: When the soil-breaking head (5) is blocked by a stone, the blocking column (13) moves and compresses the fourth spring, and the blocking column (13) releases the blockage of the first connecting groove (203), allowing water to flow into the rotating shell (9). The liquid in the rotating shell (9) increases and pushes the sliding rod (10) to move, thereby causing the soil-breaking head (5) to deflect upward; S3: When the moving direction of the soil-breaking head (5) deviates from the stone, the blocking column (13) is reset under the action of the fourth spring, so that the soil-breaking head (5) stops rotating, and the sliding member (3) continues to drive the soil-breaking head (5) to move until it reaches the longest state; S4: When the soil-breaking head (5) is extended to its longest state, the liquid pressure in the mounting shell (2) increases and pushes the push rod (16) to move, the push rod (16) drives the extrusion strip (14) to deform, and the middle part of the extrusion strip (14) moves outward; S5: When the push rod (16) moves to the limit distance, the liquid pressure in the installation shell (2) continues to increase, so that the adjustment cylinder (7) overcomes the resistance of the limit column (8) and continues to move, and the adjustment cylinder (7) moves. When the second through hole on the adjustment cylinder (7) is aligned with the next first through hole, water flows into the next installation shell (2). The above process is repeated. After all the sliding parts (3) are extended, cement is injected into the pit and the device for reinforcement. At this point, the installation is completed.
