Description

Technical Field

[0001] The present invention relates to the technical field of shaft construction, and in particular to a variable-section swirl shaft lining construction device and a construction method. Background Art

[0002] With the continuous construction and development of underground space, vertical shaft structures and their construction techniques have attracted widespread attention. During shaft construction, complex geological conditions and fluctuating ground stresses can lead to deformation and collapse of the shaft walls, seriously impacting construction progress and personnel safety. Consequently, shaft lining technology has emerged as a crucial means of ensuring shaft stability.

[0003] Shaft lining refers to a support structure built along the shaft wall, which prevents shaft wall collapse and enhances shaft stability and sealing. Currently, the slipform construction method is the primary method used for lining deep shafts. Variable-section swirl shafts, a special type of shaft, are a key component of hydropower station diversion and flood discharge systems. By varying the cross-sectional shape and size of the shaft, they can effectively regulate water flow velocity and pressure, reduce hydraulic losses, and improve water energy efficiency. Furthermore, variable-section swirl shafts are widely used in ventilation of urban underground pipeline corridors and auxiliary passages in transportation tunnels. However, for variable-section vortex shafts with complex shapes and high construction safety risks, the traditional slipform construction method has a series of problems such as complicated slipform manufacturing, inconvenient assembly and disassembly, difficulty in continuous construction and high investment. In addition, since the cross-sectional dimensions of the variable-section vortex shaft vary with depth, the conventional construction method is subject to space restrictions when supporting the formwork, and the lining formwork needs to be staggered when installed in groups, which takes up more space and is prone to collision and interference. In addition, the area below where the construction is completed usually needs support to ensure stability, and the larger lining formwork cannot pass through this area for the next stage of construction. In addition, the traditional construction method will cause the formwork to shift due to the concrete filling pressure, making it difficult to ensure construction accuracy and safety.

[0004] Therefore, exploring a continuous construction device and construction method suitable for lining concrete of large-hole, deep, and irregular-section vertical shafts to ensure efficient, accurate, and safe lining construction of variable-section swirl shafts has practical significance for the increasingly complex vertical shaft construction projects.

[0032] More specifically, the modular truss construction platform 22 is a welded steel frame structure assembled from modular truss sections, such as Figure 3 As shown, the modular truss construction platform 22 includes an inner ring truss 221 and an outer ring truss 222. The inner ring truss 221 is detachably connected to the outer side of the central truss column 12 through the transmission component 21.

A plurality of support rods 311 are provided on the main formwork 31, which are detachably connected to the telescopic member 223 through the support rods 311, and the telescopic member 223 is communicatively connected to the intelligent posture control mechanism 5. The docking formwork 32 is movably connected to the main formwork 31, and the auxiliary opening and closing assembly 33 is provided between the main formwork 31 and the docking formwork 32. The details are as follows: In order to better adapt to the lining pouring of the variable-section shaft 6, the main formwork 31 and the docking formwork 32 in this embodiment both adopt an inverted cone arc structure that is compatible with the end face of the shaft, and in order to facilitate the rapid splicing and installation operations between adjacent formworks, the main formwork 31 and the docking formwork 32 are hinged. The main formwork 31 and the docking formwork 32 both adopt assembled wooden formworks, which have good structural adaptability and can be processed and assembled according to the actual lining structure form. A splicing groove is provided on the side of the main formwork 31 away from the docking formwork 32, and a splicing ear is provided on the side of the docking formwork 32 away from the main formwork 31. The positions of the splicing ear and the splicing groove correspond and the structures are adapted to facilitate the splicing of the main formwork 31 and its unconnected docking formwork 32.

[0034] like Figure 6 As shown, the auxiliary opening and closing component 33 includes a driver 331 and a push-pull part 332. The two ends of the driver 331 are respectively connected to the main template 31 and the docking template 32. There are two groups of push-pull parts 332. The two groups of push-pull parts 332 are movably connected above and below the driver 331, and the main template 31 and the docking template 32 are respectively connected to the fixed platform 1 312 and the fixed platform 2 321. The push-pull parts 332 are respectively connected to the main template 31 and the docking template 32 through the fixed platform 1 312 and the fixed platform 2 321.

[0035] Specifically, the driver 331 adopts an electric push rod, and the two ends of the driver 331 are respectively connected to the main template 31 and the docking template 32 through mounting columns, and the driver 331 is communicated with the intelligent posture control mechanism 5; like Figure 7-10As shown, the push-pull part 332 is a connecting rod structure, and each group of push-pull parts 332 is hinged to the driver 331, and each group of push-pull parts 332 includes a connecting rod 1 3321, a connecting rod 2 3322, a connecting rod 3 3323, a connecting rod 4 3324 and a connecting column 3325. The connecting rod 1 3321 and the connecting rod 2 3322 are hinged to the fixed platform 1 312 and the fixed platform 2 321 respectively. At the same time, the connecting rod 1 3321 and the connecting rod 2 3322 are hinged at one end close to each other, and the connecting rod 3 3323 is movably connected to the connecting rod 2 3322. A mounting block 333 is fixedly connected to the driver 331, and the connecting rod 4 3324 is hinged to the mounting block 333. The connecting rod 3 3323 and the connecting rod 4 3324 are connected by the connecting column 3325. After the driver 331 is opened, During the extension and retraction process, when the driver 331 is extended or shortened, the connecting rod four 3324 and the connecting rod three 3323 rotate simultaneously under the connection of the connecting column 3325, and the connecting rod three 3323 pushes the connecting rod two 3322, so that the connecting rod two 3322 drives the connecting rod one 3321 to rotate, breaking the connecting rod dead point or forming a connecting rod dead point. Specifically here: during the installation process, the driver 331 extends, and the connecting rod two 3322 pushes the connecting rod one 3321 to form a straight line to form a connecting rod dead point, thereby pushing the docking template 32 to rotate and dock with the adjacent main template 31; during the dismantling process, the driver 331 shortens, and the connecting rod two 3322 pulls the connecting rod one 3321 to form a bent state to break the connecting rod dead point, thereby pulling the docking template 32 to rotate and separate from the adjacent main template 31.

[0036] In this embodiment, an auxiliary guide assembly 334 is further provided between the main template 31 and the docking template 32 to facilitate a more accurate connection. Figure 8 As shown, the auxiliary guide assembly 334 includes an arc-shaped track groove 3341 and an L-shaped limiter 3342, the arc-shaped track groove 3341 is fixedly connected to the inner wall of the main template 31, the L-shaped limiter 3342 is connected to the inner wall of the docking template 32, and the arc-shaped track groove 3341 and the L-shaped limiter 3342 are respectively located on the side where the main template 31 and the docking template 32 are away from each other; specifically, the L-shaped limiter 3342 includes an L-shaped rod and a limiter ball, the L-shaped rod is connected to the docking template 32, the limiter ball is connected to the end of the L-shaped rod, and the limiter ball is connected to the arc-shaped track groove. The structure of 3341 is adapted, that is, when the docking template 32 is rotated to dock with the main template 31, the limiting ball will slide inward along the arc track groove 3341, so that the docking template 32 is spliced ​​with the adjacent main template 31, and through the cooperation of the limiting ball and the arc track groove 3341 (similar to a door bolt), the relative displacement of the docking template 32 and the adjacent main template 31 in the horizontal or vertical direction is limited. Only when the docking template 32 rotates, the limiting ball will disengage from the arc track groove 3341, thereby releasing the restriction between the docking template 32 and the adjacent main template 31.

[0037] like Figure 11-13As shown, the steering mechanism 4 is located between the upper truss column and the lower truss column. The steering mechanism 4 includes an upper disc 41 and a lower disc 42. A central gear 43 is provided on the upper disc 41. A plurality of universal wheels 44 are arranged in a ring at the lower end of the central gear 43. Each universal wheel 44 can slide along the track 46 on the lower disc 42. Four power components are arranged in a square on the lower disc 42. Each power component is engaged with the central gear 43. In this embodiment, the power component adopts a motor 45. Each motor 45 is connected to a rotating shaft 451, which is engaged with the central gear 43 through the rotating shaft 451. The motor 45 is communicated with the intelligent posture control mechanism 5. The intelligent posture control mechanism 5 controls the rotation of the motor 45, thereby rotating the upper truss column, and driving the modular truss construction platform 22 to rotate to the required construction position through the upper truss column. The ball slide rail 47 provided on the lower disc 42 is fixed to the upper disc 41, so that the adjusted modular truss construction platform 22 is locked.

[0038] Reference Figure 14 The intelligent posture control mechanism 5 includes multiple sensors, a computer 51, and an editable logic controller 52. The multiple sensors are displacement sensors and pressure sensors. The driver 331 and the telescopic member 223 are respectively equipped with displacement sensors. The displacement sensors are used to record and feedback the corresponding telescopic lengths of the driver 331 and the telescopic member 223. The telescopic member 223 is also equipped with a pressure sensor. The pressure sensor is used to monitor the liquid pressure in the telescopic member 223 (i.e., the hydraulic cylinder). The computer 51 can collect and analyze the various parameters collected by each sensor in real time. The editable logic controller 52 can receive electrical signals from each sensor and convert the electrical signals into digital signals, and then generate control instructions according to the established control logic, and then send the control instructions to the power component, telescopic member 223, servo motor 211, etc., to execute the corresponding instructions for adjustment.

[0039] During the intelligent posture control process, each sensor can monitor the displacement, pressure and other information during the construction process in real time, and transmit these signals to the editable logic controller 52. The editable logic controller 52 performs logical judgment through the built-in program according to the preset height and angle. When the displacement or pressure exceeds the normal range, the editable logic controller 52 outputs a control signal to control the servo motor 211, telescopic part 223, limiter 123, etc. to perform corresponding actions to adjust the posture of the construction device. At the same time, the computer 51 is connected to the editable logic controller 52 via industrial Ethernet to display various parameters in real time, record historical data, and perform data analysis. The operator can remotely monitor the operating status of the construction site on the computer 51, adjust the control parameters of the editable logic controller 52, and realize intelligent regulation of the postures of various mechanisms of the construction device.

[0040] Example 2: Reference Figure 15 As shown, the present invention also discloses a variable cross-section swirl shaft lining construction method, and the specific construction steps are as follows: 1. The vertical shaft 6 is excavated into a hole, and sprayed concrete is constructed on the shaft wall for initial support. A concrete base plate is poured at the bottom of the shaft and positioning bolts 14 are pre-embedded; 2. Build the foundation base 11 and the central truss column 12, calibrate the center point of the central truss column 12 to ensure that the axis of the central truss column 12 coincides with the axis of the shaft 6, install the retractable truss construction mechanism 2 and the lining template mechanism 3 on the central truss column 12, and then install the intelligent posture control mechanism 5. And perform functional debugging on each sensor editable logic controller 52; 3. Operate the intelligent posture control mechanism 5, adjust the transmission assembly 21 and the steering mechanism 4, raise the modular truss construction platform 22 to a suitable height for steel bar tying, perform adaptive debugging on the modular truss construction platform 22, adjust the relative positions of the inner ring truss 221 and the outer ring truss 222, and after appropriate adjustments, fix the inner ring truss 221 and the outer ring truss 222 with positioning high-strength bolts 224 to ensure that the radial length of the modular truss construction platform 22 is suitable for steel bar tying operations. During the steel bar tying construction process, the full-section operation of the shaft 6 can be achieved by adjusting the orientation of the steering mechanism 4; 4. After completing the steel bar binding, lower the modular truss construction platform 22, connect the telescopic member 223 with the support rod 311 to install the lining formwork mechanism 3, and lift the modular truss construction platform 22 to a suitable height for concrete pouring again. Operate the intelligent posture control mechanism 5, and drive the telescopic member 223 to extend through the control command sent by the editable logic controller 52, so as to push the main formwork 31 to abut parallel to the constructed well wall to reach a predetermined dimension. Then, the driver 331 receives the control command and operates according to the predetermined program. When the driver 331 extends, Connecting rod four 3324 and connecting rod three 3323 rotate simultaneously, and connecting rod three 3323 drives connecting rod two 3322 to rotate, and connecting rod two 3322 drives connecting rod one 3321 to move until the two are collinear to form a connecting rod dead point. At this time, the docking template 32 and the adjacent main template 31 are docked, and the limiting ball at the end of the L-shaped rod enters the arc-shaped track groove 3341, strengthening the limiting effect between the docking template 32 and the adjacent main template 31, and enhancing the stability of the template connection during concrete pouring. After the construction safety inspection, the lining concrete of this section is poured; Fifth, after the concrete strength of the section reaches a predetermined value, the intelligent posture control mechanism 5 is operated to separate the lining formwork mechanism 3 from the concrete surface. Specifically, the driver 331 receives a control instruction from the editable logic controller 52 to shorten the driver 331. At this time, the connecting rod 4 3324 and the connecting rod 3 3323 rotate simultaneously, causing the connecting rod 2 3322 to rotate and break the connecting rod dead point with the connecting rod 3 3323. The connecting rod 2 3322 thereby drives the docking formwork 32 to rotate and separate from the adjacent main formwork 31. Then, the control instruction sent by the editable logic controller 52 drives the telescopic member 223 to shorten, and the telescopic member 223 drives the main formwork 31 to move toward the center truss column 12 and separate from the concrete surface. Then, the wall connecting rod 7 is installed between the constructed lining concrete and the center truss column 12 below for support. 6. Repeat steps 3 to 5 above and pour the subsequent stages in sequence until the lining concrete pouring of shaft 6 is completed.
