Description

Technical Field

[0001] This invention relates to the field of shaft lining technology, and more specifically, to a template trolley device for shaft lining. Background Technology

[0002] In tunnel and underground engineering, shafts, as vertical channels connecting underground and the ground, are widely used in fields such as mine ventilation, municipal drainage, subway construction and hydropower projects. Due to the vertical characteristics of shaft structures and narrow and enclosed working spaces, secondary lining construction has long faced technical difficulties such as low mechanization, high reliance on manual labor, and difficulty in improving construction efficiency.

[0003] Currently, slipform construction is the primary method used for secondary lining of vertical shafts. This method involves suspending an integral formwork inside the shaft and using a hydraulic lifting system or winch to continuously slide the formwork along the shaft wall, enabling continuous concrete pouring. Some projects use an integral formwork trolley combined with a winch for traction, employing a wire rope system to raise, lower, and position the formwork within the shaft. However, regardless of whether it's slipform construction or a towed formwork trolley, workers must spend extended periods on the suspended platform inside the shaft. The installation, adjustment, and dismantling of the formwork require significant manual labor. Furthermore, existing technologies are limited by the lifting system's transport capacity and inter-process interference. The vertical concrete transport efficiency is affected by multiple factors such as elevation differences and pipeline layout, making it prone to problems like pipe blockage and segregation. When using a winch-tractioned formwork trolley, the raising and lowering of the formwork requires repeated adjustments to the wire rope tension, making precise positioning difficult. Additionally, after each formwork lining is completed, the concrete must reach a certain strength before the next cycle can begin, hindering overall construction speed. In existing technologies, the movement of the formwork system within the wellbore relies on hoisting equipment such as winches and jacks at the wellhead, with lifting achieved through a wire rope system. However, the force on the wire rope is difficult to control precisely, and long-distance flexible traction can easily cause the formwork to sway and deviate. Each time the formwork moves, the length and force of the wire rope must be readjusted, making the process cumbersome and time-consuming. After the formwork is in place, it lacks the ability to walk independently. If fine-tuning of its position is required, it can only rely on manual operation of chain hoists or jacks, making it difficult to guarantee accuracy. The demolding and erection of the formwork also depend on manual operation, which is not only inefficient but also results in poor coordination among multiple sets of equipment, easily leading to uneven force on the formwork, jamming, or even local structural damage. Therefore, there is an urgent need for a formwork trolley device for shaft lining to solve the above technical problems. Summary of the Invention

[0014] A method for constructing a formwork trolley device for shaft lining, comprising the following steps: S1. Formwork erection: The control system controls the movement of the intermediate formwork support beam assembly and the side formwork amplitude beam assembly, so that the formwork assembly unfolds to the designed lining contour. S2. Pouring: Pour concrete in layers into the space between the template assembly and the well wall, and vibrate to compact it until the lining of the current section is completed. S3, Demolding: After the concrete to be poured reaches the demolding strength, the control system controls the intermediate formwork support beam assembly and the side formwork amplitude beam assembly to move in opposite directions, causing the formwork assembly to shrink and detach from the surface of the poured concrete. S4. Self-propelled: The control system controls the lower support assembly to extend and tighten the lower well wall, while the upper support assembly retracts to release the tightening state; the telescopic drive mechanism drives the telescopic beam welded piece and the upper support assembly to lift one position upwards, the upper support assembly extends and tightens the upper well wall, at this time the lower support assembly retracts to release the tightening state, the telescopic drive mechanism pulls the template support beam welded piece, the template assembly and the lower support assembly to move one position upwards, thereby lifting the entire template trolley device to the next pouring section; S5. Cyclic operation: Repeat steps S1 to S4 until the lining construction of the entire shaft is completed.

[0015] In summary, compared with the prior art, the beneficial effects of the present invention are: This invention achieves automatic formwork erection and demolding of the formwork assembly through the coordinated action of the intermediate formwork support beam assembly and the side formwork variable amplitude beam assembly. Combined with the automated coordination control of the control system, it realizes fully mechanized operation of the secondary lining process in the shaft, significantly reducing the degree of manual intervention and operational intensity. Compared with traditional slipform construction, this invention eliminates the need for pre-embedded climbing rods as lifting tracks, avoiding the risk of falls caused by insufficient climbing rod strength or improper control of concrete setting time, thus significantly improving construction safety.

[0016] By alternating tension between the upper and lower support components, coupled with the step-by-step movement of the telescopic drive mechanism, this invention achieves stable self-propelled movement of the entire machine within the shaft. During the process, at least one set of support components remains taut, forming a mechanical self-locking mechanism that effectively prevents the equipment from falling. Simultaneously, the formwork assembly adopts a multi-ring spliced, segmented hinged structure. Each ring formwork unit is formed by hinged connections between the middle formwork and the side formwork, ensuring flexible and reliable erection and demolding actions. The extension and retraction stroke of the support arms can be adjusted to accommodate shaft lining construction of different diameters. Furthermore, the overall structure is compact. The welded components of the formwork support beam and the telescopic beam employ an inner and outer nested sliding design, resulting in a small volume in the retracted state, facilitating transportation and relocation. This reduces the requirements for on-site infrastructure construction and effectively shortens the construction preparation cycle. Attached Figure Description

Detailed Implementation

[0018] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments given herein are for illustration and explanation only and are not intended to limit the present invention.

[0019] like Figures 1 to 2 As shown, a formwork trolley device for shaft lining includes: The load-bearing frame 1 includes a template support beam welded component 11 and a telescopic beam welded component 12 that extend along the axial direction of the shaft and are coaxially arranged. The telescopic beam welded component 12 is slidably nested in the inner wall of the template support beam welded component 11 and slides relative to each other along the axis of the shaft. Template assembly 2 is installed on template support beam welded part 11 via support arm 3, and is used to pour concrete to form shaft lining; The lower support assembly 4 is installed at the lower part of the template support beam welded part 11 and is used to brace the lower well wall to provide support reaction force; The upper support assembly 5 is installed on the upper part of the telescopic beam welded part 12 to brace the upper well wall to provide support reaction force; At least one telescopic drive mechanism 7 is provided, which is arranged along the vertical shaft axis. Its first drive connection part is connected to the template support beam welded part 11, and its second drive connection part is connected to the telescopic beam welded part 12. The telescopic drive mechanism 7 drives the template support beam welded part 11 and the telescopic beam welded part 12 to move relative to each other along the axial direction. Control system, used for the automated control of the template trolley device.

[0020] In this invention, the template support beam welded component 11 and the telescopic beam welded component 12 adopt a coaxial sleeve structure. The telescopic beam welded component 12 is slidably nested in the inner wall of the template support beam welded component 11, forming a set of axial sliding pairs. This allows the two components to move relative to each other along the vertical shaft axis, while the radial direction is effectively constrained, thus ensuring the concentricity and verticality of the entire machine during self-propelled movement. In conjunction with the alternating tightening actions of the upper and lower support components, the telescopic drive mechanism 7 achieves the step-like self-propelled movement of the entire machine through its extension and retraction. During the upward lifting stage, the lower support component 4 tightens the lower shaft wall, the upper support component 5 retracts to release the tightening, and the telescopic drive mechanism 7 extends, driving the telescopic beam welded component 12, along with its upper support component 5, to move upward one position. During the upward traction stage, the upper support component 5 tightens the upper shaft wall, the lower support component 4 retracts to release the tightening, and the telescopic drive mechanism 7 retracts, tractioning the template support beam welded component 11, along with the template assembly 2 and the lower support component 4, to move upward one position. Once the above two stages are completed, the machine completes one stepping cycle and moves upward one workstation. Repeating this cycle will enable the machine to continuously move independently within the shaft.

[0021] Traditional shaft lining equipment, such as slipform construction, relies on external winches for lifting or pre-embedded climbing rods for sliding, and the equipment itself lacks mobility. This invention, through a combined design of "inner and outer nested sliding pairs + telescopic drive mechanism + alternating upper and lower supports," enables the formwork trolley device to achieve autonomous step-by-step movement, eliminating the need for external traction equipment. This reduces reliance on external lifting equipment such as shaft winches, simplifies equipment configuration on the construction site, and significantly improves the flexibility and efficiency of equipment movement within the shaft.

[0022] In terms of safety, at any given moment during the stepping movement, at least one set of support components is in a taut state, reliably fixing the entire machine to the well wall and ensuring that the telescopic drive mechanism 7 always operates with a fixed fulcrum. Unlike slipform construction, which relies on the strength of the climbing rod, this solution uses the mechanical tautness of the support components to form a self-locking mechanism. Even if the hydraulic system unexpectedly loses pressure, the balance valve on the support components can still remain taut, fundamentally eliminating the risk of equipment falling. Operators can work safely on the stable operating platform 124 without worrying about the equipment suddenly slipping.

[0023] This technology is independent of wellhead hoisting equipment, and the travel distance of the stepping movement can be flexibly set according to construction needs. Theoretically, it can be applied to vertical shafts of any depth, breaking through the technical bottleneck of "limited climbing rod length" in traditional slipform construction, and is particularly suitable for ultra-deep vertical shaft construction. In working conditions with uneven well walls and complex geological conditions, the support components are connected to the support shoes through universal ball joints 6, which can adapt to the undulations of the well wall surface and always maintain a surface contact and tight support state, providing stable and reliable support reaction force.

[0024] like Figures 3 to 9 As shown, in a preferred embodiment of the present invention, the template assembly 2 is composed of multi-ring template units spliced ​​along the shaft axis. Each ring template unit includes a middle template weldment 21, a first side template weldment 22, and a second side template weldment 23. The first side template weldment 22 and the second side template weldment 23 are respectively symmetrically hinged to the radial sides of the middle template weldment 21. The upper and lower adjacent ring template units are positioned and fixedly connected in a circumferential direction to form a continuous template working surface extending along the shaft axis.

[0025] The first side template weldment 22 and the second side template weldment 23 are symmetrically hinged on the radial sides of the middle template weldment 21, respectively. They can rotate relative to the middle template around the hinge axis, realizing the opening and closing of the template assembly 2. In the upright formwork state, the first side template weldment 22 and the second side template weldment 23 open outward around the hinge axis, forming a closed annular lining contour together with the middle template. Concrete can be poured at this time. In the demolding state, the first side template weldment 22 and the second side template weldment 23 close inward around the hinge axis, and the overall radial dimension of the template assembly 2 is reduced, separating from the poured concrete surface and providing space for the equipment to move on its own. Compared with slipform, the biggest difference is that the template can actively shrink, rather than relying on the relative sliding separation between the concrete and the template. This avoids the adhesion or cracking caused by improper control of the concrete setting time. The present invention enables the side templates to actively close through the hinge structure, realizing the complete separation of the template and the concrete. It eliminates the need for precise control of the initial setting time and slip speed of the concrete, reducing the difficulty of controlling construction parameters.

[0026] Among them, the upper and lower adjacent ring template units are positioned and fixedly connected in a one-to-one correspondence along the ring direction. Specifically, the middle template weldment 21 of the upper ring is connected to the middle template weldment 21 of the lower ring, the first side template weldment 22 of the upper ring is connected to the first side template weldment 22 of the lower ring, and so on. After splicing, a continuous template working surface extending along the shaft axis is formed.

[0027] In a preferred embodiment of the present invention, the support arm 3 includes several ring support components, the number of which corresponds to the template unit. Each ring support component includes a middle template support beam assembly 31 and two side template amplitude-changing beam assemblies 32. One end of the middle template support beam assembly 31 is mounted on the side wall of the template support beam welded part 11, and the other end is supported between two adjacent middle template welded parts 21, which is used to fix the radial position of the adjacent middle template welded parts 21. One end of one side template amplitude-changing beam assembly 32 of each ring support assembly is hinged to the side wall of the template support beam welded part 11, and the other end is hinged to the first side template welded part 22. One end of the other side template amplitude-changing beam assembly 32 is hinged to the side wall of the template support beam welded part 11, and the other end is hinged to the second side template welded part 23. The side template amplitude-changing beam assembly 32 is used to drive the erection and demolding actions of the first side template and the second side template.

[0028] During demolding, since the supporting end of the intermediate template support beam assembly 31 simultaneously contacts the intermediate template weldment 21 of the upper and lower rings, the radial position of the intermediate templates of the two rings can be fixed at the same time, ensuring a smooth transition between adjacent rings and effectively preventing radial misalignment caused by uneven force or installation errors between adjacent rings. This allows the multi-ring template unit to form an integral load-bearing structure during the pouring process, making it more resistant to the lateral pressure of concrete. The side template variable beam assembly 32 is connected to the first and second side template weldments and the template support beam weldment 11 by hinges, allowing the side template variable beam assembly 32 to automatically adjust its angle with the rotation of the first and second side template weldments during the expansion and contraction process. This avoids the jamming that may occur with rigid connections and adapts to the angle changes of the first and second side template weldments during the opening / closing process.

[0029] like Figures 10 to 12As shown, in a preferred embodiment of the present invention, the intermediate template support beam assembly 31 includes a first outer beam weldment 311, a first telescopic beam weldment 312, and a demolding cylinder 313. The first telescopic beam weldment 312 is slidably nested within the first outer beam weldment 311, and the demolding cylinder 313 is used to drive the first telescopic beam weldment 312 to extend and retract relative to the first outer beam weldment 311. The side template luffing beam assembly 32 includes a second outer beam weldment 321, a second telescopic beam weldment 322, and a luffing cylinder 323. The second telescopic beam weldment 322 is slidably nested within the second outer beam weldment 321, and the luffing cylinder 323 is used to drive the second telescopic beam weldment 322 to extend and retract relative to the second outer beam weldment 321.

[0030] like Figures 3 to 9 As shown, in a preferred embodiment of the present invention, the intermediate template weldment 21 includes a third arc-shaped panel 211, two third arc-shaped connecting plates 212, two third end connecting plates 213, and several third intermediate stiffeners 214. The outer arc surface of the third arc-shaped panel 211 is used to form the inner wall of the lining. The two third arc-shaped connecting plates 212 have long arc segments that match the curvature of the ends of the third arc-shaped panel 211. The long arc segments of the two third arc-shaped connecting plates 212 are respectively fixed to the upper and lower ends of the third arc-shaped panel 211.

The outer arc surface of the first arc-shaped panel 221 is used to form the inner wall of the lining. The first arc-shaped panel 221 and the first arc-shaped connecting plates 222 are matched with the end curvature of the third arc-shaped panel 211. The long arc segments of the two first arc-shaped connecting plates 222 are respectively fixed to the upper and lower ends of the first arc-shaped panel 221. A first connecting seat weldment 225 is provided on the radial inner side plate surface of each first arc-shaped connecting plate 222 for hinged connection with the support arm 3. Two first end connecting plates 223 extend along the vertical shaft axis and are respectively fixed at the left and right ends of the first arc panel 221, and are located between the upper and lower first arc connecting plates 222. Four first hinge ear plates 226 are fixed on the side of the first end connecting plate 223 near the middle template weldment 21 away from the first arc panel 221, and are arranged at intervals along the vertical shaft axis. Each pair forms a hinge connection with the third hinge ear plate 216 of the middle template weldment 21. Several first intermediate stiffening plates 224 extend along the vertical shaft axis and are fixed at intervals along the arc length of the first arc panel 221 on the inner arc surface of the first arc panel 221. The second side template weldment 23 includes a second arc-shaped panel 231, two second arc-shaped connecting plates 232, two second end connecting plates 233, and several second intermediate stiffening plates 234. The outer arc surface of the second arc-shaped panel 231 is used to form the inner wall of the lining. The curvature of the second arc-shaped panel 231 and the second arc-shaped connecting plates 232 are matched with the end curvature of the third arc-shaped panel 211. The long arc segments of the two second arc-shaped connecting plates 232 are respectively fixed to the upper and lower ends of the second arc-shaped panel 231. A second connecting seat weldment 235 is provided on the radial inner side plate surface of each second arc-shaped connecting plate 232 for hinged connection with the support arm 3. Two second end connecting plates 233 extend along the vertical shaft axis and are fixedly installed at the left and right ends of the second arc panel 231, respectively, and are located between the upper and lower second arc connecting plates 232. Four second hinge ear plates 236 are fixedly installed on the side of the second end connecting plate 233 near the middle template weldment 21 away from the second arc panel 231, which are spaced apart along the vertical shaft axis. Each pair forms a hinge connection with the third hinge ear plate 216 of the middle template weldment 21.

Concrete pouring holes 24 are provided on the first arc-shaped panel 221, the second arc-shaped panel 231, and the third arc-shaped panel 211.

[0031] The intermediate template weldment 21 forms an annular end frame through the third arc-shaped connecting plate 212 fixed at both ends. Two bent connecting plates 215 spaced apart on the radial inner side of the third arc-shaped connecting plate 212 form support points and are fixedly connected to the intermediate template support beam assembly 31, so that the support beam assembly can simultaneously support the two adjacent intermediate template weldments 21, thereby accurately fixing their radial position and preventing joint misalignment. The third end connecting plate 213 fixed at both ends of the third arc-shaped panel 211 and the two third hinge ear plates 216 spaced apart along the vertical shaft axis provide precise hinge connection points for the side template.

[0032] The first and second side template weldments adopt a curvature design that matches that of the intermediate template weldment 21. The first and second arc-shaped connecting plates at their upper and lower ends form an end frame. The first and second connecting seat weldments on the radially inner side plate provide hinge mounting points for the side template luffing beam assembly 32, facilitating the opening and closing of the first and second side template weldments. Four first and second hinge ear plates are fixed on the first and second end connecting plates near the intermediate template weldment 21, spaced apart along the shaft axis. Each pair is hinged to the third hinge ear plate 216 of the intermediate template weldment 21 via pins, forming a double-hinge connection structure. This structure can effectively transmit radial and tangential forces while allowing the first and second side template weldments to rotate around the hinge axis, achieving smooth erection and demolding under the drive of the luffing cylinder 323. In addition, the intermediate stiffening plates extending along the shaft axis and spaced along the arc length form a grid-like reinforcement structure on the inner arc surface of the panel, significantly improving the overall rigidity and deformation resistance of the template, ensuring that the template maintains its designed curvature when subjected to concrete lateral pressure. The segmented structure and modular design make each template lightweight and small in size, facilitating processing, manufacturing, transportation, hoisting, and on-site assembly. At the same time, if a template is damaged, it can be replaced individually, significantly reducing maintenance costs.

[0033] like Figures 13 to 18 As shown, in a preferred embodiment of the present invention, the template support beam welding component 11 includes a first main beam welding component 111 extending along the shaft axis. A plurality of intermediate template support mounting base welding components 112, which are spaced apart along the shaft axis, are fixed on the outer peripheral wall of the first main beam welding component 111 for mounting intermediate template support beam assembly 31. Each intermediate template support mounting base welding component 112 has a side template variable beam hinge ear plate 113 on each circumferential side for hinged to one end of the side template variable beam assembly 32. A plurality of lower support mounting base welding components 114 are also fixed on the lower outer peripheral wall of the first main beam welding component 111 for mounting lower support assembly 4. The first main beam welding component 111 is also provided with a first drive mechanism mounting base welding component 115 for connecting with the first drive connection part of the telescopic drive mechanism 7, and a plurality of reinforcing structural components welded to the first main beam welding component 111. The telescopic beam welded component 12 includes a second main beam welded component 121 extending along the vertical shaft axis. The outer wall size of the second main beam welded component 121 matches the inner wall size of the first main beam welded component 111. The second main beam welded component 121 is slidably nested in the inner cavity of the first main beam welded component 111. Several upper support mounting base welded components 122 are fixed on the upper outer peripheral wall of the second main beam welded component 121 for mounting the upper support assembly 5. The second main beam welded component 121 is also provided with a second drive mechanism mounting base welded component 123 for connecting with the second drive connection part of the telescopic drive mechanism 7, and an operating platform 124 set at the top of the second main beam welded component 121.

[0034] Through the integrated layout of "intermediate template support mounting seat welded part 112 + hinged ear plate 113 of circumferential side template amplitude beam" on the outer periphery of the first main beam welded part 111, the space reuse of multi-point support and multi-point drive is realized. The installation of all template support and drive mechanisms is completed on the limited outer periphery area, resulting in a compact structure and balanced force.

[0035] In a preferred embodiment of the present invention, the lower support assembly 4 includes at least three sets of lower support cylinders 41, which are evenly distributed along the circumference of the template support beam welded part 11. The cylinder body end of each set of lower support cylinders 41 is fixed to the outer peripheral wall of the template support beam welded part 11, and the piston rod end is connected to the lower support shoe 42 through a universal ball joint 6. The lower support shoe 42 is used to contact and tighten the lower well wall when the lower support cylinder 41 extends outward along the vertical shaft radially. The upper support assembly 5 includes at least three sets of upper support cylinders 51, which are evenly distributed along the circumference of the telescopic beam welded part 12. The cylinder body end of each set of upper support cylinders 51 is fixed to the outer peripheral wall of the telescopic beam welded part 12, and the piston rod end is connected to the upper support shoe 52 through a universal ball joint 6. The upper support shoe 52 is used to contact and tighten the upper well wall when the upper support cylinder 51 extends outward along the vertical shaft radially.

[0036] The upper and lower support components 4 directly transfer the weight of the entire machine and the construction load to the well wall through the support shoes. The load-bearing frame 1 mainly bears axial pressure and bending moment, rather than tension. Compared with the traditional slipform "climbing rod tension" scheme, the stress distribution method of this scheme is more in line with the mechanical properties of steel, and the structural stress distribution is more reasonable and reliable.

[0037] As a preferred embodiment of the present invention, the control system includes a controller, a first pressure sensor disposed on the upper support assembly 5 and a second pressure sensor disposed on the lower support assembly 4. The first pressure sensor is used to detect the contact pressure between the upper support assembly 5 and the well wall, and the second pressure sensor is used to detect the contact pressure between the lower support assembly 4 and the well wall. The controller adjusts the cylinder stroke of the upper support assembly 5 and the lower support assembly 4 respectively according to the feedback signals of the first pressure sensor and the second pressure sensor.

[0038] As a preferred embodiment of the present invention, the telescopic drive mechanism 7 is one or more combinations of a lifting cylinder, an electric push rod mechanism, a wire rope winch mechanism, or a screw and nut mechanism.

[0039] like Figures 19 to 20 As shown, a method for constructing a formwork trolley device for shaft lining, the formwork trolley device for shaft lining includes the following steps: S1. Formwork erection: The control system controls the movement of the intermediate formwork support beam assembly 31 and the side formwork amplitude beam assembly 32, so that the formwork assembly 2 unfolds to the designed lining outline. S2. Pouring: Pour concrete in layers into the space between the formwork assembly 2 and the well wall, and vibrate to compact it until the lining of the current section is completed. S3, Demolding: After the concrete to be poured reaches the demolding strength, the control system controls the intermediate formwork support beam assembly 31 and the side formwork amplitude beam assembly 32 to move in opposite directions, so that the formwork assembly 2 shrinks and detaches from the surface of the poured concrete. S4, Self-propelled: The control system controls the lower support component 4 to extend and tighten the lower well wall, while the upper support component 5 retracts and releases the tightening state; the telescopic drive mechanism 7 drives the telescopic beam welded part 12 and the upper support component 5 to lift one position upwards, the upper support component 5 extends and tightens the upper well wall, at this time the lower support component 4 retracts and releases the tightening state, the telescopic drive mechanism 7 pulls the template support beam welded part 11, the template assembly 2 and the lower support component 4 to move one position upwards, thereby lifting the entire template trolley device to the next pouring section; S5. Cyclic operation: Repeat steps S1 to S4 until the lining construction of the entire shaft is completed.

[0040] The hoisting and overall assembly of the template trolley device is as follows: the template support beam welded component 11 is hoisted into the bottom of the shaft and installed in place. The lower support component 4, the side template variable beam component 32, and the middle template support beam component 31 are installed sequentially on the template support beam welded component 11. Each template unit of the template assembly 2 is hoisted into the shaft in sequence and assembled in the order of the middle template welded component 21, the first side template welded component 22, and the second side template welded component 23. Adjacent template units are positioned and fixedly connected in a circumferential direction to form a continuous template working surface extending along the shaft axis. The telescopic drive mechanism 7 is hoisted and its first drive connection part is installed on the template support beam welded component 11. Then, the telescopic beam welded component 12 is hoisted and its outer wall is slidably nested into the inner wall of the template support beam welded component 11. The second drive connection part of the telescopic drive mechanism 7 is installed on the telescopic beam welded component 12. Finally, the support component 5 and the hydraulic and electrical system are hoisted and installed to complete the assembly of the whole machine.

[0041] After assembly, the overall axis is adjusted. The stroke of the support cylinders of each lower support assembly 4 is adjusted to ensure that the stroke of all lower support cylinders 41 is consistent, thus ensuring the concentricity of the lining. The stroke of the demolding cylinders 313 of all intermediate template support beam assemblies 31 is adjusted to ensure that the stroke of all demolding cylinders 313 is consistent, thus preventing template jamming and local structural cracking. The stroke of the luffing cylinders 323 of all side template luffing beam assemblies 32 is adjusted to ensure that the stroke of all luffing cylinders 323 is consistent, thus preventing template jamming and local structural cracking. The upper support assembly 5 detects the contact pressure with the initial lining well wall through the first pressure sensor. The control system adjusts the stroke of each upper support cylinder 51 according to the pressure feedback signal until the stroke of all upper support cylinders 51 is consistent after sensing the set pressure, thus completing the axis adjustment.

[0042] It should be understood that the above embodiments are one or more embodiments of the present invention. There are many other embodiments and variations based on the present invention. Any variations and modifications made by those skilled in the art without making pioneering innovations are within the protection scope of the present invention.
