Description

Technical Field

[0001] The invention relates to the technical field of foundation pit support equipment, in particular to a fluidized silt soil foundation pit support system. Background Art

[0002] Foundation pit support refers to a series of structural reinforcement measures taken during the construction of underground projects to ensure the stability of the foundation pit and the safety of the surrounding environment. Its main purpose is to prevent soil collapse, control ground settlement, and ensure safety during construction. Among them, there are various forms of foundation pit support, including steel sheet piles, concrete retaining walls, underground continuous walls, soil nail walls, etc. These retaining structures effectively share the soil pressure by penetrating into the surrounding soil layers, thereby maintaining the stability of the foundation pit. At the same time, the support system (such as lateral steel supports and ground anchors) plays a lateral resistance role to prevent the soil from sliding and retreating. The foundation pit support design needs to be based on detailed soil surveys and mechanical analysis, and factors such as geological conditions, groundwater levels, construction depths, and loads on surrounding buildings should be considered. Engineers will develop detailed support plans during the design phase and conduct real-time monitoring during the construction process to cope with possible geological changes and structural deformations. Through scientific and reasonable support design and construction management, construction risks can be effectively reduced, construction safety and project quality can be ensured. In the construction of steel sheet piles, in order to ensure the correct axis of the pile position and the verticality of the pile, control the driving accuracy of the pile, prevent the buckling and deformation of the sheet pile and improve the penetration capacity of the pile, it is generally necessary to set a certain rigidity and sturdy guide frame, also known as a construction purlin.

[0003] A Chinese patent discloses a steel sheet pile driving device (patent application number 202410804509.5), which includes a steel sheet pile body, a plurality of steel sheet pile bodies are interlocked with each other, and guide rods are tightly attached to the side walls of the steel sheet pile body, and a supporting mechanism is provided on the side wall of the guide rod. A fixing mechanism is provided at both ends of the guide rod, and a moving mechanism is installed on the fixing mechanism, and a limiting mechanism is movably provided on the moving mechanism.

[0004] In the existing steel sheet pile installation process, in order to prevent the steel sheet piles from shifting when driven into the ground, manual cooperation with the crane is required to guide the steel sheet piles into the guide frame. This process has certain safety hazards. In order to address this problem, the above-mentioned patent clamps and guides the steel sheet piles through guide rods. However, the above-mentioned patent still requires cumbersome manual operations, which is inefficient. In addition, for some usage scenarios that require splicing of longer steel sheet piles, the longer guide rods are prone to bend when subjected to external forces, which may lead to a reduction in clamping force and a decrease in guiding accuracy, making it difficult to play a stable guiding role for the steel sheet piles. In order to solve these problems, a new foundation pit support system based on fluidized silt soil is proposed. Summary of the invention

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Example 1: Please refer to Figures 1 to 7 In an embodiment of the present invention, a fluidized silt foundation pit support system includes a clamping component 1, a directional component 2 for limiting the rotation direction of the clamping component 1, a limiting component 3 for preventing the directional component 2 from expanding in the opposite direction, a sliding component 4 for increasing the clamping force of the clamping component 1, a steel plate 6 for foundation pit support, and an oiling component 5 for filling the steel plate 6 with butter;

[0042] The directional component 2 is slidably connected to the left and right side walls of the clamping component 1, the limiting component 3 is located on the upper side of the clamping component 1, the sliding component 4 is located on the lower side of the clamping component 1, and the oil injection component 5 is located inside the clamping component 1, including the clamping component 1 and a steel plate 6 located on the lower side of the clamping component 1;

[0043] The clamping assembly 1 includes a drive box 101, the lower inner wall of the drive box 101 is rotatably connected to two mutually meshing drive gears 102, a fixed plate 103 is fixedly connected inside the drive box 101, a motor 104 is fixedly connected to the upper side wall of the fixed plate 103, and the output end of the motor 104 is fixedly connected to one of the drive gears 102, and conductive rails 105 are arranged on the lower sides of the two drive gears 102, and the conductive rails 105 are both slidably connected with sliders 106 inside the two conductive rails 105, and the sliders 106 can be reciprocated on the conductive rails 105 by using the lead screw installed inside the conductive rails 105, and the sliders 106 are fixedly connected to the drive gears 102. When the sliders 106 are in the conductive rails 105, the sliders 106 are fixedly connected to the drive gears 102. When the two ends of the part are at the vertex position, the axis of the driving gear 102 and the axis between the convex pressure plate 107 or the concave pressure plate 108 on the lower side of the conductive slide rail 105 are exactly in the same vertical plane, and the lower side walls of the two conductive slide rails 105 are rotatably connected with the convex pressure plate 107 and the concave pressure plate 108, and the convex pressure plate 107 on the lower side of one conductive slide rail 105 corresponds to the concave pressure plate 108 on the lower side of the other conductive slide rail 105, and the convex pressure plate 107 on the lower side of the other conductive slide rail 105 corresponds to the concave pressure plate 108 under this conductive slide rail 105, so that the two convex pressure plates 107 and the two concave pressure plates 108 are divided into a front group of pressure plates and a rear group of pressure plates, and the shapes of the convex pressure plates 107 and the concave pressure plates 108 match the front and rear side walls of the steel plate 6;

[0044] When the motor 104 is started, it can drive the two driving gears 102 to rotate in different directions, so that the two driving gears 102 can simultaneously drive the two conductive slide rails 105 to rotate through the slider 106. When the conductive slide rail 105 rotates, it can drive a group of convex pressure plates 107 and concave pressure plates 108 on the rear side to move to the front side.

[0045] The directional assembly 2 includes two transverse plates 201, and the two transverse plates 201 are slidably connected to the rear side walls of the convex pressure plate 107 and the concave pressure plate 108. The rear side walls of the convex pressure plate 107 and the concave pressure plate 108 are fixedly connected with sliding strips, which are inserted into the sliding grooves of the rear side walls of the convex pressure plate 107 and the concave pressure plate 108 to achieve sliding connection. When the rear group of pressure plates rotates forward, the transverse plate 201 will be unfolded and the transverse plate 201 will be separated from the front group of pressure plates. Two sliding blocks 203 are slidably connected to the inner wall of the drive box 101, and a bracket 202 is fixedly connected between the sliding block 203 and the transverse plate 201. A thrust spring 204 is fixedly connected between the sliding block 203 and the inner side wall of the drive box 101. The directional assembly 2 also includes a support plate 205 fixedly connected to the inside of the drive box 101. The upper side wall of the support plate 205 is rotatably connected with a synchronous gear 206. The two sliding blocks 2 03 The opposite side walls are fixedly connected with racks 207 meshing with synchronous gears 206, and racks 207 are slidably connected to the inner wall of the drive box 101. When the rear pressure plate rotates to the front side, the convex pressure plate 107 and the concave pressure plate 108 will simultaneously push the cross plate 201 to unfold the cross plate 201. At this time, the cross plate 201 can effectively prevent the convex pressure plate 107 and the concave pressure plate 108 from rotating, so that the opposite side of the convex pressure plate 107 and the concave pressure plate 108 is always facing the steel plate 6. Through the synchronous gear 206, the two cross plates 201 can achieve the purpose of synchronous movement, making the structure run more stably. After the rear pressure plate rotates to the front side, it effectively clamps the new steel plate 6. The squeezing of the convex pressure plate 107 and the concave pressure plate 108 can be used to stably position the steel plate 6 and help the new steel plate 6 and the old steel plate 6 lock to correspond to each other.

[0046] The limiting assembly 3 includes a limiting cylinder 301 fixedly connected to the upper side wall of the driving box 101, a moving plate 302 is slidably connected inside the limiting cylinder 301, a second gear 304 is rotatably connected to the lower inner wall of the limiting cylinder 301, a first gear 303 is rotatably connected to the lower inner wall of the moving plate 302, a square telescopic rod 305 and a return spring 306 are fixedly connected between the first gear 303 and the second gear 304, a third gear 307 meshing with the first gear 303 is rotatably connected to the upper inner wall of the moving plate 302, a square rod 309 is fixedly connected to the lower side wall of the third gear 307, and a socket matching the square rod 309 is drilled on the upper side wall of the synchronous gear 206. When the synchronous gear 206 rotates, the synchronous gear 206 will also drive the second gear 304 to rotate, the second gear 304 drives the first gear 303 to rotate, and the first gear 303 drives the third gear 307 to rotate. Therefore, when the synchronous gear 206 rotates, the third gear 307 will rotate synchronously in the same direction. As long as the square rod 309 and the socket of the synchronous gear 206 are in a corresponding state, this mechanism will allow the third gear 307 to move up and down at will, and the square rod 309 can be inserted into the synchronous gear 206. A one-way bearing 308 is fixedly connected between the third gear 307 and the inner wall of the limiting cylinder 301. The inner wall is fixedly connected with an electromagnet 310 which is magnetically connected to the moving plate 302. When the motor 104 drives the conductive slide rail 105 to rotate to the second half, the electromagnet 310 is in a starting state, so that the electromagnet 310 generates a magnetic force to push the moving plate 302 downward, so that the square rod 309 can be inserted into the synchronous gear 206, and then the one-way bearing 308 realizes the one-way rotation function of the synchronous gear 206. When the convex pressure plate 107 and the concave pressure plate 108 clamp the new steel plate 6, the cross plate 201 will also change from the original expanded state to the closed state under the elastic force of the thrust spring 204. When the steel plate 6 is being hammered, the synchronous gear 20 The one-way rotation function of 6 can effectively prevent the two horizontal plates 201 from unfolding at this time, so that the two horizontal plates 201 can better resist the convex pressure plate 107 and the concave pressure plate 108. When the steel plate 6 is driven into the specified depth underground, the slider 106 is driven by the conductive slide rail 105 to move, so that the drive box 101 moves further forward and the whole becomes the initial state. When the motor 104 drives the conductive slide rail 105 to rotate in the first half, the horizontal plate 201 is in the unfolded state. At this time, the electromagnet 310 is in the off-state, and the square rod 309 will no longer be inserted into the synchronous gear 206. At this time, the synchronous gear 206 will no longer be in the one-way rotation state.

[0047] The sliding assembly 4 includes a slide groove 401 excavated on the upper ends of the convex pressure plate 107 and the concave pressure plate 108, and the lower side wall of the driving box 101 is fixedly connected to a fixed block 403, and the left and right side walls of the fixed block 403 are fixedly connected to a Z-shaped slide plate 402, and the Z-shaped slide plate 402 is fixedly connected inside the slide groove 401. During the movement of the driving box 101, the driving box 101 will also drive the fixed block 403 to move, so that the fixed block 403 drives the Z-shaped slide plate 402, prompting the Z-shaped slide plate 402 to move from the slide groove 401 in the rear group pressure plate to the slide groove 401 in the front group pressure plate.

[0048] It is worth noting that the front end of the Z-shaped slide plate 402 is configured to be an outwardly expanding Z-shaped structure, which not only enables the Z-shaped slide plate 402 to be inserted into the front slide groove 401, but also enables the inclined plate of the Z-shaped slide plate 402 to better apply the clamping force between the convex pressure plate 107 and the concave pressure plate 108, so that the clamping force between the convex pressure plate 107 and the concave pressure plate 108 can prevent the clamping assembly 1 from falling on the steel plate 6; in addition, when the clamping assembly 1 initially needs to be fixed on a single steel plate 6, it is first necessary to hang the clamping assembly 1 on the rear side of the steel plate 6, and then use the aforementioned method of clamping the steel plate 6 to fix the clamping assembly 1 on the steel plate 6.

[0049] Example 2: Please refer to Figures 8 to 10 Based on Example 1, the oil injection assembly 5 includes a mounting groove 501 excavated inside the convex pressure plate 107, the mounting groove 501 is provided with a mounting frame 502 fixedly connected to the convex pressure plate 107, a rubber cylinder 503 is rotatably connected to the mounting frame 502, and the left and right side walls of the mounting frame 502 are rotatably connected to a disk 504 fixedly connected to the rubber cylinder 503, and the inner wall of the mounting groove 501 is fixedly connected to two pressurizing cylinders 505, and the two pressurizing cylinders 505 are slidably connected with pistons 506 inside, and a hinged rod 507 is hinged between the piston 506 and the disk 504, and an oil storage chamber 508 is excavated inside the convex pressure plate 107, and a one-way pipe 509 is connected between the oil storage chamber 508 and the pressurizing cylinder 505, and the two pressurizing cylinders 505 are connected with the same The oil storage cylinder 510 has one-way oil drain pipes 511 connected to its left and right side walls, and the one-way oil drain pipes 511 are arranged through the convex pressure plate 107. When the steel plate 6 is moved by being hammered, the steel plate 6 will contact the rubber cylinder 503, and the steel plate 6 drives the rubber cylinder 503 to rotate under the action of friction, so that the rubber cylinder 503 drives the piston 506 to move back and forth through the hinge rod 507, and then cooperates with the one-way fluidity of the one-way pipe 509 and the one-way oil drain pipe 511, so that the butter inside the oil storage chamber 508 can be drawn into the pressure cylinder 505 through the one-way pipe 509, and then discharged from the one-way oil drain pipe 511 through the oil storage cylinder 510, so that the butter discharged from the one-way oil drain pipe 511 is just opposite to the locking mouth of the steel plate 6, thereby improving the installation efficiency of the steel sheet piles.

[0050] It is worth noting that, since the rubber tube 503 is made of rubber material, the rubber tube 503 itself has a certain elastic force, which can effectively prevent the concave pressure plate 108 from affecting the clamping of the steel plate 6 .

[0051] The working principle of the present invention is:

[0052] First, when in use, the staff uses a crane to hang the steel plate 6 between the two horizontal plates 201, and then starts the motor 104. The motor 104 drives the two driving gears 102 to rotate, so that the two driving gears 102 simultaneously drive the two conductive slide rails 105 to rotate through the slider 106. When the conductive slide rail 105 rotates, it can drive the convex pressure plate 107 and the concave pressure plate 108 of the rear side to move to the front side. In this process, the convex pressure plate 107 and the concave pressure plate 108 of the rear side push the two horizontal plates 201 to unfold. When the convex pressure plate 107 and the concave pressure plate 108 rotate, the convex pressure plate 107 and the concave pressure plate 108 can only move but not rotate through the horizontal plate 201. In this way, they can play a stable clamping role on the hung steel plate 6, and use the concave and convex surfaces of the convex pressure plate 107 and the concave pressure plate 108 to effectively position the steel plate 6.

[0053] When the convex pressure plate 107 and the concave pressure plate 108 clamp the steel plate 6, the cross plate 201 changes from the expanded state to the closed state under the thrust of the thrust spring 204. In the process of changing to the closed state, when the output end of the motor 104 rotates to the range of 90 degrees to 180 degrees, the electromagnet 310 is in the starting state. This monitoring and driving process is a prior art and will not be repeated here. The electromagnet 310 after startup generates a magnetic force to push the movable plate 302 downward, so that the square rod 309 can be inserted into the synchronous gear 206, and then the one-way rotation function of the synchronous gear 206 is realized through the one-way bearing 308. In this way, the two cross plates 201 can better resist the convex pressure plate 107 and the concave pressure plate 108, thereby improving the stability of the clamping of the steel plate 6 and further reducing the probability of the steel plate 6 being offset during hammering.

[0054] When the steel plate 6 is hammered by the vibrating hammer, the friction force will drive the rubber cylinder 503 to rotate, so that the rubber cylinder 503 drives the piston 506 to move back and forth through the hinge rod 507, and then cooperates with the one-way flowability of the one-way tube 509 and the one-way oil discharge pipe 511, so that the butter inside the oil storage chamber 508 can be drawn into the pressure cylinder 505 through the one-way tube 509, and then discharged from the one-way oil discharge pipe 511 through the oil storage cylinder 510, so that the butter discharged from the one-way oil discharge pipe 511 is just opposite to the lock mouth of the steel plate 6.

[0055] When the steel plate 6 is driven into the ground to a specified depth, the conductive slide rail 105 drives the drive box 101 to move forward through the slider 106, so that the clamping assembly 1 can continuously move forward in units of one steel plate 6. When the steel plate 6 needs to be installed again, just repeat the above steps.

[0056] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
