Technical Field

[0001] The present invention relates to the technical field of drainage in foundation construction, and in particular to drainage equipment and method for geotechnical engineering foundation construction. Background Art

[0002] Geotechnical engineering is to solve rock and soil engineering problems, including foundation and foundation, slope and underground engineering problems. At present, during the construction of engineering foundation, water is easily accumulated inside the foundation pit or groundwater leaks into the foundation pit. Drainage equipment is needed to pump out the water inside the foundation pit to facilitate subsequent construction. The most commonly used drainage equipment is the pumping device, which pumps out the accumulated water inside the foundation pit through a pipeline and performs corresponding discharge treatment. At present, drainage equipment has become intelligent and can automatically control various data such as pumping time. It is flexible and convenient to use. For example, the Chinese patent publication number is CN114183335A, which discloses a geotechnical engineering foundation construction intelligent drainage equipment and a method of use. The geotechnical engineering foundation construction intelligent drainage equipment provided by it is convenient for drainage of different depths, and can be filtered to reduce environmental pollution.

[0003] However, traditional drainage equipment has some shortcomings. For example, when pumping water inside the foundation pit, the pumping pipe at the water inlet of the water pump is inside the water pit or even at the bottom. This causes the water flow to stir up the dirt at the bottom of the foundation pit during pumping, causing the pumped sewage to have an adverse effect on the pumping equipment. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a drainage device and method for geotechnical engineering foundation construction.

[0005] The technical solution adopted by the present invention is as follows: Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.

[0006] This technical solution achieves efficient and stable drainage function under complex terrain through an arc-shaped installation track, a through-installation trough, a through-movable shaft, upper and lower movable connecting plates, an installed buoyancy plate, connecting pipes and extraction components, recoil components, and protective components. Specifically, the shape of the arc-shaped installation track can adapt to the complex terrain of the geotechnical engineering foundation, ensuring that the equipment can be stably installed and adapt to the curved surface of the foundation; the through-installation trough provides an installation and movement track, so that the equipment can flexibly adjust its position and posture; the through-movable shaft realizes dynamic adjustment of the equipment through its rotation and movement; the lower limit disc and the upper movable connecting plate serve as the bottom support and top connection point respectively to ensure the stability of the entire structure; the installed buoyancy plate utilizes the buoyancy of water to help the equipment remain stable in the water, while facilitating the lifting and adjustment of the equipment; the connecting fixed block is used to connect the buoyancy plate to ensure the integrity of the overall structure; the first connecting pipe is used to transport drainage liquid, and the recoil component regularly cleans the liquid in the pipe. The protective component is used to protect the pipeline from damage by the external environment and extend its service life; the driving component provides power so that the upper movable connecting plate and its connected parts can be moved and adjusted as needed; the lifting component lifts the installed buoyancy plate and its connected parts to realize the lifting function of the equipment; the extraction component extracts groundwater through the first connecting pipe to realize the drainage function; when a blockage occurs in the pipeline, the recoil component starts to use high-pressure water flow to clear the blockage in the pipeline to ensure smooth drainage; the installation of the buoyancy plate uses the buoyancy of water to provide additional support for the equipment, so that it remains stable in the water, and the stability and drainage efficiency of the equipment are adjusted by adjusting the position and number of the buoyancy plates. In summary, the entire equipment realizes a stable drainage function in complex terrain and changing environments through the coordinated work of various components.

[0007] In addition, the drainage equipment for geotechnical engineering foundation construction proposed in the present invention also has the following additional technical features: According to one embodiment of the present invention, the driving assembly includes a connecting mounting seat fixedly connected to one side of the upper movable connecting plate, the lower surface of the connecting mounting seat is fixedly connected to a servo motor, the output shaft of the servo motor is fixedly connected to a rotating connecting gear, the outer surface of the arc-shaped mounting track is fixedly connected to an arc-shaped fixed gear ring, and the rotating connecting gear is meshingly connected with the arc-shaped fixed gear ring.

[0008] The technical solution realizes the precise control and adjustment function of the whole drainage equipment through the driving of the servo motor, the transmission of the rotating connecting gear and the guiding effect of the arc-shaped mounting track. Specifically, the rotating connecting gear is directly fixed on the output shaft of the servo motor. When the servo motor is started, its output shaft will drive the rotating connecting gear to rotate together; the arc-shaped fixed gear ring is used as a matching component of the rotating connecting gear and is fixedly connected to the outer surface of the arc-shaped mounting track; when the servo motor is started, the rotating connecting gear will roll along the tooth surface of the arc-shaped fixed gear ring, thereby driving the whole upper movable connecting plate and the parts connected thereto to move on the arc-shaped mounting track; the servo motor is used as the power source of the driving assembly, and is started and stopped by receiving the control signal, and controls the rotation speed and direction of the rotating connecting gear; the rotating connecting gear is used as a transmission component to transmit the power of the servo motor to the whole driving assembly. When the rotating connecting gear rolls on the arc-shaped fixed gear ring, it synchronously drives the upper movable connecting plate and the parts connected thereto to move together; the arc-shaped mounting track is used as a guiding component of the driving assembly, and limits the moving trajectory of the driving assembly through its specific shape and size, thereby realizing precise control of the whole drainage equipment.

[0009] According to one embodiment of the present invention, the recoil assembly includes a plurality of branch nozzles fixedly connected to the outer surface of the first connecting pipe, the plurality of branch nozzles are arranged in a circular array, and a one-way valve is installed on the outer surface of the branch nozzle.

[0010] This technical solution realizes effective backwashing and cleaning of the drainage system through the annular array arrangement of the branch nozzles and the installation of the one-way valve, prevents the occurrence of blockage, improves the drainage efficiency, and ensures the long-term stable operation of the system. Specifically, the arrangement of the annular array of the branch nozzles ensures that the water flow can be evenly distributed during backwashing, forming an all-round flushing effect, improving the coverage of the flushing, and enhancing the uniformity and efficiency of the flushing; the one-way valve is used to control the flow direction of the water flow, ensuring that the water flow can only be ejected from the branch nozzles and cannot flow in the opposite direction, preventing sewage or impurities from flowing back into the first connecting pipe during the backwashing process, causing secondary pollution or blockage. When backwashing is required, high-pressure water is injected into the first connecting pipe and sprayed out through the branch nozzles. Since the branch nozzles are arranged in an annular array, the sprayed water will form an all-round flushing force, effectively removing dirt and impurities on the inner wall and surrounding of the first connecting pipe; the backwashing component removes dirt and impurities in the pipe through regular backwashing operations to keep the pipe unobstructed.

[0011] According to one embodiment of the present invention, the protection component includes a sleeve fixing plate fixedly connected to the outer surface of the first connecting pipe, the lower surface of the sleeve fixing plate is fixedly connected to a threaded mounting ring, and the outer surface of the threaded mounting ring is threadedly connected to a protection mesh cover.

[0012] This technical solution achieves effective protection and protection of the first connecting pipe through the close cooperation of the sleeve fixing plate, the threaded mounting ring and the protective mesh cover, while providing convenience for replacement. Specifically, the sleeve fixing plate is used to ensure that the protective component can be firmly installed on the pipe and is not easy to fall off or loosen; the protective mesh cover is firmly installed on the pipe, and the degree of fixation and tightness of the protective mesh cover can be controlled by adjusting the tightness of the threaded connection; the protective mesh cover is used to prevent debris from entering the first connecting pipe, thereby protecting the pipe and the internal fluid from contamination and damage; the fine mesh of the protective mesh cover can block most debris while allowing the fluid to pass smoothly.

[0013] According to one embodiment of the present invention, the extraction assembly includes a water pump body fixedly connected to the upper surface of the upper movable connecting plate, the inlet of the water pump body is fixedly connected to a second connecting pipe, the end of the second connecting pipe away from the water pump body is fixedly connected to a connecting telescopic hose, the end of the connecting telescopic hose away from the second connecting pipe is fixedly connected to the first connecting pipe, and the outlet of the water pump body is fixedly connected to a third connecting pipe.

[0014] This technical solution realizes the effective extraction and delivery of fluid through the close cooperation of the water pump body, the connecting pipe and the connecting telescopic hose. Specifically, when the water pump body is started, it will generate a negative pressure area, attracting the fluid in the first connecting pipe to enter the water pump body through the connecting telescopic hose and the second connecting pipe. Under the action of the water pump body, the fluid is compressed and output to the designated position through the third connecting pipe, realizing the extraction and delivery of the fluid. By using the connecting telescopic hose, the distance and angle between the first connecting pipe and the water pump body can be easily adjusted to adapt to different working environments and conditions.

[0015] According to one embodiment of the present invention, the lifting assembly includes a driving cylinder fixedly connected to the lower surface of the upper movable connecting plate, the piston end of the driving cylinder is fixedly connected to a fixed long rod, the end of the fixed long rod away from the driving cylinder is fixedly connected to an upward push mounting plate, and the upward push mounting plate is located below the buoyancy plate.

[0016] This technical solution realizes the stable lifting and lowering operation of the buoyancy board through the close cooperation of the driving cylinder, the fixed long rod and the push-up mounting plate. Specifically, when the driving cylinder receives the start signal, its piston will begin to extend. Since the fixed long rod is fixedly connected to the piston end, the extension of the piston will drive the fixed long rod and the push-up mounting plate to move upward together; when the push-up mounting plate contacts the buoyancy board, it will continue to lift it up until it reaches a predetermined position; after the buoyancy board is lifted up, the push-up mounting plate will provide stable support for it, and when the buoyancy board needs to be lowered, it is only necessary to control the piston of the driving cylinder to retract, and the buoyancy board can be slowly lowered through the fixed long rod and the push-up mounting plate; in the lifting assembly, the piston of the driving cylinder, the fixed long rod and the push-up mounting plate are performed in sequence, and the thrust generated by the cylinder is transmitted to the push-up mounting plate through the fixed long rod, and then transmitted to the buoyancy board by the push-up mounting plate.

[0017] According to an embodiment of the present invention, three connecting rods are fixedly connected to the lower surface of the arc-shaped mounting rail, and the three connecting rods are equidistantly distributed.

[0018] In this technical solution, three connecting rods ensure that the rail can evenly distribute the load when it is stressed, avoiding deformation or damage caused by local overload. The connecting rods are easy to disassemble and reinstall, so when the arc-shaped installation rail fails, maintenance and replacement work can be carried out quickly, which not only improves installation efficiency but also reduces installation costs.

[0019] To achieve the above-mentioned purpose, the present invention also provides a drainage method for geotechnical engineering foundation construction.

[0020] A drainage method for geotechnical engineering foundation construction comprises the following steps: S1. The arc-shaped installation track is installed on the outer periphery of the top of the foundation pit through three connecting rods, and the buoyancy board is installed inside the foundation pit. The buoyancy board floats on the water surface inside the foundation pit. Before pumping water from the foundation pit, the water in the foundation pit is allowed to settle for a period of time. After the water surface is clear, the pumping pump body is started. Through the action of the pumping pump body, the water inside the foundation pit enters the second connecting pipe through the first connecting pipe and the connecting telescopic hose, and is finally discharged through the third connecting pipe; S2. Regularly open the one-way valve on the branch nozzle to allow part of the water entering the first connecting pipe to be sprayed out through the branch nozzle. The water sprayed out from the branch nozzle rushes toward the protective mesh to reduce floating objects gathered at the protective mesh; S3, start the driving cylinder, the piston end of the driving cylinder brings the fixed long rod up, the fixed long rod brings the push-up mounting plate up, the push-up mounting plate brings the mounting buoyancy plate up, so that the mounting buoyancy plate brings the first connecting pipe up, so that the first connecting pipe and the protective net cover are separated from the water surface; S4. Restart the servo motor, and the output shaft of the servo motor rotates with the rotating connecting gear. Since the rotating connecting gear is meshed with the arc-shaped fixed gear ring, the rotating connecting gear rotates and moves at the same time, so that the upper movable connecting plate moves on the surface of the arc-shaped mounting track, and the first connecting pipe and the protective mesh cover are moved to another water surface. The driving cylinder is started again to lower the installation buoyancy plate, so that the installation buoyancy plate floats on the water surface again, and the water pump body is started again to pump water.

[0021] This technical solution uses three connecting rods to firmly install the arc-shaped installation track on the outer periphery of the top of the foundation pit, ensuring the stability and reliability of the entire drainage system; after installing the buoyancy plate to float on the water surface inside the foundation pit, let the water settle for a period of time to remove impurities, and then start the pump body. Using the strong suction of the pump body, the water inside the foundation pit passes through the first connecting pipe and the connecting telescopic hose, and finally smoothly enters the second connecting pipe, and is effectively discharged through the third connecting pipe; by regularly operating the one-way valve on the branch nozzle, the sprayed water flow is used to flush the protective mesh cover, effectively reducing the floating objects gathered at the mesh cover, and ensuring the continuous and efficient operation of the drainage system; by starting the driving cylinder, the piston end of the cylinder is used to drive the fixed long rod The push-up mounting plate rises, thereby raising the mounting buoyancy plate and the first connecting pipe as a whole, realizing the smooth separation of the first connecting pipe from the protective mesh cover, which not only avoids the friction and loss between the pipe and the mesh cover, but also improves the flexibility and efficiency of drainage; by starting the servo motor, the output shaft of the motor is used to drive the rotating connecting gear to rotate. Due to the meshing connection between the gear and the arc-shaped fixed gear ring, the rotating connecting gear can move while rotating, thereby driving the upper movable connecting plate and the first connecting pipe to move along the arc-shaped mounting track to another water surface, and starting the driving cylinder again to lower the mounting buoyancy plate, so that the buoyancy plate floats on the water surface again, and starting the water pump body again to pump water, which not only expands the drainage range, but also improves the drainage efficiency and uniformity.

[0022] Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention starts the servo motor, and the output shaft of the servo motor rotates with the rotating connecting gear. Since the rotating connecting gear is meshed and connected with the arc-shaped fixed gear ring, the rotating connecting gear rotates and moves, so that the upper movable connecting plate moves on the surface of the arc-shaped mounting track, and the first connecting pipe and the protective net cover are moved to another water surface. The driving cylinder is started again to lower the mounting buoyancy plate, so that the mounting buoyancy plate floats on the water surface again, and the pump body is started again to pump water, so that the first connecting pipe moves to other places for extraction, which can avoid long-term pumping in one place, and the water flow is always stirred, causing the accumulated water in that place to become turbid; (2) The present invention starts the driving cylinder, and the piston end of the driving cylinder drives the fixed long rod to rise, the fixed long rod drives the push-up mounting plate to rise, the push-up mounting plate drives the mounting buoyancy plate to rise, so that the mounting buoyancy plate drives the first connecting pipe to rise, so that the first connecting pipe and the protective net cover are separated from the water surface, thereby allowing the first connecting pipe to move away from the water surface, ensuring that the first connecting pipe does not stir the water surface when moving; (3) The present invention periodically opens the one-way valve on the branch nozzle so that part of the water entering the first connecting pipe is sprayed out through the branch nozzle. The water sprayed out from the branch nozzle rushes toward the protective mesh cover, thereby reducing floating objects gathered at the protective mesh cover and avoiding blockage at the water pumping point.

S2, regularly open the one-way valve on the branch nozzle 17, so that part of the water entering the first connecting pipe 13 is sprayed out through the branch nozzle 17, and the water sprayed from the branch nozzle 17 rushes to the protective net cover 16, thereby reducing the floating objects gathered at the protective net cover 16; S3, start the driving cylinder 22, the piston end of the driving cylinder 22 brings the fixed long rod 23 up, the fixed long rod 23 brings the push-up mounting plate 24 up, the push-up mounting plate 24 brings the mounting buoyancy plate 11 up, so that the mounting buoyancy plate 11 brings the first connecting pipe 13 up, so that the first connecting pipe 13 and the protective net cover 16 are separated from the water surface; S4, restart the servo motor 7, the output shaft of the servo motor 7 rotates with the rotating connecting gear 8, and since the rotating connecting gear 8 is meshed and connected with the arc-shaped fixed gear ring 9, the rotating connecting gear 8 rotates and moves, so that the upper movable connecting plate 4 moves on the surface of the arc-shaped mounting track 1, and the first connecting pipe 13 and the protective net cover 16 are moved to another water surface, and the driving cylinder 22 is started again to lower the installation buoyancy plate 11, so that the installation buoyancy plate 11 floats on the water surface again, and the water pump body 18 is started again to pump water.

[0041] like Figures 1 to 6 As shown, the present technical solution securely mounts the arc-shaped mounting track 1 on the outer periphery of the top of the foundation pit through three connecting plug rods 25, thereby ensuring the stability and reliability of the entire drainage system; after installing the buoyancy plate 11 to float on the water surface inside the foundation pit, the water is allowed to settle for a period of time to remove impurities, and then the pump body 18 is started. By utilizing the strong suction force of the pump body 18, the water inside the foundation pit passes through the first connecting pipe 13 and the connecting telescopic hose 20, and finally smoothly enters the second connecting pipe 19, and is effectively discharged through the third connecting pipe 21; by regularly operating the one-way valve on the branch nozzle 17, the sprayed water flow is used to flush the protective mesh cover 16, effectively reducing the floating objects gathered at the mesh cover, and ensuring the continuous and efficient operation of the drainage system; by starting the driving cylinder 22, the piston end of the cylinder is used to drive the fixed long rod 23 and the upward mounting plate 24 rise, thereby causing the mounting buoyancy plate 11 and the first connecting pipe 13 to rise as a whole, thereby achieving smooth separation of the first connecting pipe 13 from the protective mesh cover 16, which not only avoids friction and loss between the pipe and the mesh cover, but also improves the flexibility and efficiency of drainage; by starting the servo motor 7, the output shaft of the motor is used to drive the rotating connecting gear 8 to rotate. Due to the meshing connection between the gear and the arc-shaped fixed gear ring 9, the rotating connecting gear 8 can move while rotating, thereby driving the upper movable connecting plate 4 and the first connecting pipe 13 to move along the arc-shaped mounting track 1 to another water surface, and starting the driving cylinder 22 again to lower the mounting buoyancy plate 11, so that the buoyancy plate floats on the water surface again, and starting the water pump body 18 again to pump water, which not only expands the drainage range, but also improves the drainage efficiency and uniformity.
