Technical Field

[0001] The invention relates to the technical field of construction engineering, and in particular to a micro-precipitation construction device and method in a vertical shaft and horizontal passage. Background Art

[0002] In some underground projects, such as subways and tunnels, due to the complexity of geological conditions, groundwater may bring many problems to the construction, such as water gushing and landslides, which seriously affect the construction safety and progress. In order to solve these problems, effective precipitation measures are needed to lower the groundwater level to below the construction surface to ensure the smooth progress of the construction. Micro-precipitation construction in vertical shafts and horizontal passages usually adopts methods such as micro-stop wells in the tunnel. By setting precipitation wells in the tunnel, groundwater is pumped out to achieve the purpose of lowering the groundwater level. This method has the advantages of convenient construction and little impact on the surrounding environment. It can effectively solve the precipitation problem in underground engineering construction.

[0003] The micro-precipitation construction in the vertical shaft and horizontal passage requires the arrangement of precipitation wells. However, in the normal arrangement of precipitation wells, the precipitation wells are often arranged manually after drilling holes with a drilling rig, which requires a lot of manpower. In addition, the precipitation wells are large in size and heavy in weight. A slight carelessness may cause engineering accidents and injure workers. Therefore, there is an urgent need for a micro-precipitation construction device in the vertical shaft and horizontal passage. Summary of the invention

[0004] The object of the present invention is to provide a micro-dewatering construction device and method in a vertical shaft and a horizontal passage to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a micro-precipitation construction device and method in a vertical shaft horizontal passage, comprising a driving mechanism, the driving mechanism comprising a device housing, the front and rear sides of the device housing are fixedly connected to hydraulic telescopic rods, the front side of the device housing is fixedly connected to a counterweight block, the left side of the device housing is fixedly connected to a support block, the left top end of the device housing is fixedly connected to a mounting block, the bottom end of the device housing is installed with a driving assembly, and the inner wall of the device housing is provided with a moving unit; A clamping unit is provided on the surface of the mobile unit; The clamping unit includes a clamping shell, the inner wall of the clamping shell is fixedly connected to a cylinder, the output end of the cylinder is fixedly connected to a pushing block, the front and rear sides of the pushing block are rotatably connected to a transmission rod, the end of the transmission rod away from the pushing block is rotatably connected to a clamping arm, the inner wall of the clamping shell is rotatably connected to a rotating rod, and the front and rear sides of the clamping shell are fixedly connected to a slider.

[0006] The cylinder drives the push block to move to the left, and the push block drives the transmission rod to move during the movement, and the transmission rod drives the rotating connection of the clamping arm to move, so that the clamping arm can clamp, and at the same time, the push block moves forward and cooperates with the clamping arm to clamp to fix the precipitation well. The device can be moved through the driving assembly, and a receiver can be set up separately for remote control. At the same time, a hydraulic telescopic rod is provided to enable the device to run stably after arriving at the construction site, and a counterweight block is provided on the surface of the device casing to increase the stability of the device during construction.

[0008] The provision of anti-skid pad 1 and anti-skid pad 2 makes the clamping unit more stable during the clamping process. By limiting the rotation rod, the transmission rod can only move to both sides and the connection between the clamping arm and the transmission rod moves outward, so that the outer end of the clamping arm can clamp inward through the rotation rod as a lever.

[0009] As a preferred embodiment, the moving unit includes a first motor, the bottom end of the first motor is fixedly connected to a moving frame, the inner wall of the moving frame is rotatably connected to a lead screw 1, the inner wall of the moving frame is fixedly connected to a slide rail, the right side of the moving frame is fixedly connected to a rotating frame, the surface of the rotating frame is rotatably connected to an electric telescopic rod, the end of the electric telescopic rod away from the rotating frame is rotatably connected to a sliding rod, the front and rear ends of the sliding rod are both threadedly connected to a lead screw 2, the right end of the lead screw 2 is fixedly connected to a bevel gear 2, the surface of the bevel gear 2 is meshed with a bevel gear 1, the end of the bevel gear 1 away from the bevel gear 2 is fixedly connected to a dual-axis motor, and the right bottom end of the moving frame is fixedly connected to a connecting block.

[0010] The double-axis motor drives the bevel gear 1 fixedly connected to the output end to rotate, and the bevel gear 2 is driven to rotate by the meshing of the bevel gear 1 and the bevel gear 2, which in turn drives the lead screw 2 to rotate. The rotation of the lead screw 2 can control the sliding rod to slide on its surface. When the electric telescopic rod is completely retracted, the double-axis motor drives the sliding rod and then drives the electric telescopic rod to move to the right so that the mobile frame can lie flat, making it convenient for workers to place the precipitation well in the clamping unit.

[0011] As a preferred embodiment, the left end of the lead screw 2 is rotatably connected to the device housing, the right end of the lead screw 2 passes through the device housing and is fixedly connected to bevel gear 1, and the surface of the dual-axis motor is fixedly connected to the device housing.

[0012] As a preferred implementation manner, the inner wall of the connecting block is rotatably connected to the mounting block, and the output end of the first motor is fixedly connected to the lead screw.

[0013] The movable frame can be controlled to rotate around the mounting block by the extension and retraction of the electric telescopic rod, and the first motor drives the lead screw to rotate.

[0014] As a preferred embodiment, the surface of the lead screw 1 is threadedly connected to the clamping shell, and the surface of the slide rail is slidably connected to the inner wall of the slider.

[0015] The first motor drives the lead screw to rotate so that the clamping unit slides on its surface, and the slide rail is used to limit the clamping unit so that it will not deviate from the running track.

[0016] The steps are as follows: S1: Geological survey: Before construction, a detailed survey of the geological conditions around the vertical shaft and horizontal passage is conducted to understand the groundwater level, aquifer distribution and other information to provide a basis for the design of the dewatering plan; S2: Dewatering well arrangement: Dewatering wells are arranged around the vertical shaft and horizontal passage according to the geological survey results; S3: Water pump installation: Install a water pump in the precipitation well to pump out the groundwater; S4: Laying of drainage pipes to discharge the pumped groundwater out of the shaft through the drainage pipes; S5: Precipitation monitoring: During the precipitation construction process, the groundwater level and ground subsidence are monitored, and the precipitation plan is adjusted in time to ensure construction safety; S6: Construction precautions: During the construction process, pay attention to safety to avoid accidents such as collapse and water seepage.

[0017] As a preferred implementation mode, in the arrangement of S precipitation wells, the precipitation wells are evenly distributed around the foundation pit or underground project to avoid precipitation blind spots. Taking the surrounding environment into consideration, the precipitation wells are avoided to be arranged near important facilities such as buildings, roads, and underground pipelines to avoid affecting them. Combined with the construction technology, according to the construction technology such as the foundation pit excavation sequence and the support form, the precipitation wells are reasonably arranged to facilitate construction and maintenance. On-site tests and monitoring are carried out. Before the actual construction, on-site pumping tests are carried out to determine the best precipitation well arrangement plan. At the same time, the groundwater level, ground subsidence, etc. should be monitored during the construction process, and the operation of the precipitation wells should be adjusted in time.

[0018] As a preferred implementation, during the installation of the S water pump, according to the location of the precipitation well and the drainage requirements, select a stable, dry place that is easy to operate and maintain to install the water pump, and ensure that the installation foundation is firm and flat and can withstand the weight of the water pump and the vibration generated during operation. Finally, carefully place the water pump on the installation foundation, and use bolts or other fixing devices to fix the water pump to ensure that the water pump is stable. The water inlet pipe should be connected to the precipitation well, and the water outlet pipe should be connected to the drainage pipe to ensure that the connection is tight and there is no water leakage. According to the electrical requirements of the water pump, correctly connect the water pump to the power supply, pay attention to the correctness and safety of the wiring, and avoid problems such as short circuit and leakage. After the installation is completed, debug and inspect the water pump, start the water pump, and check whether the water pump is operating normally, including water flow, pressure, noise, etc. At the same time, check whether there is water leakage at each connection point.

[0019] As a preferred implementation mode, during the laying of the S drainage pipe, the route and layout of the drainage pipe are planned according to the location, drainage volume and drainage direction of the precipitation well. According to the design requirements, the trench for the drainage pipe is excavated. The depth and width of the trench are determined according to the specifications of the pipe and the soil conditions to ensure that the bottom of the trench is flat and solid. The quality and specifications of the drainage pipe are checked to ensure that the pipe has no defects such as damage and cracks. The pipe is cut and connected as needed, and the drainage pipe is placed in the trench. It is laid according to the designed slope and direction. Note that the connection between the pipes must be tight to avoid water leakage. After the pipe is laid, the pipe is fixed in the trench with pipe clamps or other fixing devices to prevent the pipe from moving or floating. According to the length and layout of the drainage pipe, the inspection well is reasonably set. After the drainage pipe is laid and fixed, the trench is backfilled. The backfilling should be compacted in layers to ensure the density of the backfill soil to avoid ground subsidence. After the drainage pipe is laid, a water flow test is carried out to check whether the pipe is unobstructed and whether there is any water leakage.

[0020] Compared with the prior art, the beneficial effects achieved by the present invention are: First, the present invention effectively drives the push block to move smoothly to the left through the operation of the cylinder. In the process of the movement of the push block, it fully plays its role, driving the transmission rod to move accordingly. The movement of the transmission rod then drives the rotating connection of the clamping arm to produce corresponding displacement. In this process, with the help of the limiting function of the rotating rod, the transmission rod can only move in the directions of both sides, and the connection between the clamping arm and the transmission rod is extended outward. In this way, the outer end of the clamping arm uses the rotating rod as a lever support point to perform a clamping action inward. At the same time, the push block not only moves to the left, but also advances forward, cooperating with the clamping arm to jointly realize The precipitation well is firmly clamped, thereby achieving the purpose of fixing the precipitation well. By starting the first motor, the lead screw is driven to rotate at a uniform speed. The rotation of the lead screw enables the clamping shell to move in the up and down directions. At the same time, the slide rail plays a good limiting role on the clamping shell, ensuring the stability and accuracy of its movement. Through such a design, the clamping unit can smoothly carry out the installation of the precipitation well, improving the efficiency and quality of construction, and solving the problem that the precipitation well is often manually arranged after the hole is drilled by a drilling rig, which requires a lot of manpower, and the precipitation well is large in size and weight, and the slightest carelessness may cause engineering accidents and injuries to workers.

[0021] Secondly, the present invention starts to operate through a dual-axis motor, driving the bevel gear 1 fixedly connected to its output end to rotate at a uniform speed. During this process, bevel gear 1 and bevel gear 2 are meshed with each other, thereby driving bevel gear 2 to start rotating. As bevel gear 2 rotates, lead screw 2 is further driven to start rotating. Through the rotation of lead screw 2, the slide bar can be effectively controlled to slide smoothly on its surface. At the same time, with the help of the telescopic function of the electric telescopic rod, the rotation of the mobile frame can be controlled so that it can rotate around the mounting block. When the electric telescopic rod completes the contraction action, the dual-axis motor will drive the slide bar, and then drive the electric telescopic rod to move to the right. Such operation enables the mobile frame to be in a lying state, which provides great convenience for workers to place the precipitation well in the clamping unit. This design not only improves work efficiency, but also reduces the labor intensity of workers, making the entire operation process more convenient and efficient.

[0022] Third, the present invention enables the device to achieve a convenient mobile function through the action of the driving component. Moreover, in order to further improve the convenience of operation, a receiver can be separately provided to realize remote control of the device. In this way, the operator can accurately control the device from a certain distance, thereby improving the flexibility and efficiency of the work. At the same time, the device is equipped with a hydraulic telescopic rod. When the device arrives at the construction site, the hydraulic telescopic rod can be extended to form a solid support with the ground, thereby ensuring that the device can maintain stable operation during the construction process, avoiding shaking or displacement, etc., and providing reliable guarantee for the smooth progress of the construction. Counterweight blocks are arranged on the surface of the device casing. The presence of these counterweight blocks increases the overall weight of the device, thereby effectively improving the stability of the device during construction, especially in the face of some factors that may cause instability of the device, such as external force interference or uneven terrain, etc. The counterweight blocks can play an important role in enabling the device to maintain balance and stability, thereby ensuring the quality and safety of the construction.

[0033] In the arrangement of S2 precipitation wells, the precipitation wells should be evenly distributed around the foundation pit or underground project to avoid precipitation blind spots. The surrounding environment should be taken into consideration to avoid arranging precipitation wells near important facilities such as buildings, roads, underground pipelines, etc. to avoid affecting them. Combined with the construction technology, according to the construction technology such as the foundation pit excavation sequence and support form, the precipitation wells should be reasonably arranged to facilitate construction and maintenance. On-site tests and monitoring should be carried out. Before actual construction, on-site pumping tests should be carried out to determine the best precipitation well arrangement plan.

[0034] When installing the S3 water pump, according to the location of the precipitation well and drainage requirements, choose a stable, dry place that is easy to operate and maintain to install the water pump, and ensure that the installation foundation is firm and flat, and can withstand the weight of the water pump and the vibration generated during operation. Finally, carefully place the water pump on the installation foundation, and use bolts or other fixing devices to fix the water pump to ensure that the water pump is stable. The water inlet pipe should be connected to the precipitation well, and the water outlet pipe should be connected to the drainage pipe to ensure that the connection is tight and there is no water leakage. According to the electrical requirements of the water pump, correctly connect the water pump to the power supply, pay attention to the correctness and safety of the wiring, and avoid problems such as short circuit and leakage. After the installation is completed, debug and inspect the water pump, start the water pump, and check whether the water pump is operating normally, including water flow, pressure, noise, etc. At the same time, check whether there is any leakage at each connection point.

[0035] During the laying of S4 drainage pipes, the route and layout of the drainage pipes shall be planned according to the location, drainage volume and drainage direction of the precipitation wells. The trenches for the drainage pipes shall be excavated according to the design requirements. The depth and width of the trenches shall be determined according to the specifications of the pipes and the soil conditions to ensure that the bottom of the trenches is flat and solid. The quality and specifications of the drainage pipes shall be checked to ensure that the pipes are free of defects such as damage and cracks.

[0036] Working principle: Through the operation of the cylinder 202, the push block 203 is effectively driven to move smoothly to the left. In the process of the movement of the push block 203, it fully plays its role, driving the transmission rod 204 to move accordingly. The movement of the transmission rod 204 then drives the rotating connection of the clamping arm 205 to produce corresponding displacement. In this process, with the help of the limiting function of the rotating rod 208, the transmission rod 204 can only move in the two directions, and the connection between the clamping arm 205 and the transmission rod 204 is extended outward. In this way, the outer end of the clamping arm 205 uses the rotating rod 208 as a lever support point to clamp inward. Action, at the same time, the pushing block 203 not only moves to the left, but also moves forward, cooperating with the clamping arm 205 to achieve a stable clamping of the precipitation well, thereby achieving the purpose of fixing the precipitation well. By starting the first motor 301, the lead screw 304 is driven to rotate at a uniform speed. The rotation of the lead screw 304 enables the clamping shell 201 to move in the up and down directions. At the same time, the slide rail 303 has a good limiting effect on the clamping shell 201, ensuring the stability and accuracy of its movement. Through such a design, the clamping unit 20 can smoothly carry out the installation of the precipitation well, thereby improving the efficiency and quality of the construction. In addition, the dual-axis motor 308 can start running, driving the bevel gear 1 309 fixedly connected to its output end to rotate at a uniform speed. During this process, the bevel gear 1 309 and the bevel gear 2 310 are meshed with each other, thereby driving the bevel gear 2 310 to start rotating. As the bevel gear 2 310 rotates, the lead screw 2 311 is further driven to start rotating. Through the rotation of the lead screw 2 311, the slide bar 307 can be effectively controlled to slide smoothly on its surface. At the same time, with the help of the telescopic function of the electric telescopic rod 306, the rotation of the movable frame 302 can be controlled so that it can rotate around the mounting block 104. When the electric telescopic rod 306 completes the contraction action, the dual-axis motor 308 will drive the slide bar 307, and then drive the electric telescopic rod 306 to move to the right. Such operation enables the movable frame 302 to be in a lying state, which provides great convenience for workers to place the precipitation well in the clamping unit 20. This design not only improves work efficiency, but also reduces the labor intensity of workers, making the entire operation process more convenient and efficient.
