Description

Technical Field

[0001] This application relates to the field of shaft construction, and in particular to a method for one-time lifting of a large-diameter deep shaft with a gradient surface structure using integral slipforming. Background Technology

[0002] The raw water pipeline project of the water plant mainly addresses the problem of insufficient urban water supply. This is achieved by setting up water intake towers at reservoir locations, constructing vertical shafts at various locations throughout the city, and connecting them with pipelines. Water from the intake towers is pumped to nearby vertical shafts, and the water is then transported through pipelines to these shafts throughout the city. Pumping stations are located within the vertical shafts to extract water from the shafts and use it for urban water supply. The vertical shafts near the water intake towers are large in diameter and deep, and also serve as TBM (Toyota Burmester Machine) launch shafts. These large-diameter, deep shafts are functionally divided into areas such as an intake forebay, drainage pump room, stairwell, elevator shaft, and ventilation shaft.

[0003] In the construction steps of large-diameter deep shaft, the outline of the shaft is first installed at the construction location of the large-diameter deep shaft to construct a continuous wall and enclose the shaft construction area. Then, the soil inside the shaft is excavated to form a shaft construction pit. Then, the formwork is erected and the concrete is poured to finally form a large-diameter deep shaft with multiple compartments. The water intake pool is separated from other working compartments by a central partition wall.

[0004] The aforementioned technologies have the following drawbacks: In actual deep shaft applications, the water pressure is greater at deeper locations within the shaft, so the central partition wall needs to be thicker to improve its structural strength. However, this also requires a large amount of concrete and steel reinforcement, resulting in high material costs. In addition, the installation and dismantling of conventional formwork is cumbersome, affecting the overall construction efficiency of deep shafts. Therefore, there is still room for improvement. Summary of the Invention

[0005] In order to improve the construction efficiency of deep vertical shafts and reduce the amount of concrete and steel reinforcement materials used, this application provides a method for the one-time lifting construction of a large-diameter deep vertical shaft with a gradient surface structure using integral slipforming.

[0006] This application provides a method for the integral slipforming and one-time lifting construction of a large-diameter deep vertical shaft gradient surface structure, which adopts the following technical solution:

[0007] A method for integral slipforming and single-lifting construction of a large-diameter deep vertical shaft with a gradient surface structure includes:

[0008] S1: Arrange material feeding pipes around the construction pit of the deep vertical shaft, and hoist the finished steel bars to the bottom of the construction pit and tie and fix them.

[0009] S2: After the first section of steel reinforcement is tied, a slipform equipment is installed in the construction pit of the deep shaft. The slipform equipment includes the formwork structure of the inlet pool and the formwork structure of multiple working chambers, as well as a climbing system. The construction gap between the outer side of the formwork structure of the inlet pool and the inner wall of the deep shaft construction pit, as well as the construction gap between the outer side of the formwork structure of the working chambers and the inner wall of the deep shaft construction pit, are used to pour and form the main body of the deep shaft. The construction gap between the formwork structure of the inlet pool and the formwork structure of multiple working chambers is used to pour and form the central partition wall. The formwork structure of the inlet pool includes a fixed formwork, a movable formwork, and an adjustable formwork. The fixed formwork extends along the outline of the inner wall of the deep shaft construction pit, the movable formwork extends along the length of the central partition wall, and the adjustable formwork is used to seal the gap between the movable formwork and the fixed formwork. The fixed formwork, the movable formwork, and the adjustable formwork together enclose the formwork structure of the circumferentially closed inlet pool.

[0010] S3: Concrete is poured into the construction pit of the deep shaft through the material discharge pipe to form the first section of the main body of the deep shaft;

[0011] S4: After the concrete reaches a certain strength, a section of finished steel bar is hoisted down and tied and fixed. Then, the slipform equipment is driven by the climbing system to climb upward, so that the outer side of the movable template of the slipform equipment is always in close contact with the side wall of the cast concrete structure. Then, the position of the movable template is adjusted away from the fixed template to reduce the distance between the movable template and the working chamber template structure. Then, the position of the adjustment template is adjusted accordingly to fill the gap between the movable template and the fixed template and maintain the sealing state of the pre-intake pool template structure.

[0012] S5: Repeat S3 and S4 to finally form the main body of the deep vertical shaft in the construction pit, and form a central partition wall structure with gradually changing thickness between the working chamber and the water inlet pool. The cross-section of the central partition wall structure gradually narrows from bottom to top.

[0013] By adopting the above technical solution, climbing formwork equipment is manufactured for multi-compartment structures in deep vertical shafts. The formwork structure corresponding to the inlet pool is composed of fixed formwork, movable formwork, and adjustable formwork. The movable formwork can move relative to the fixed formwork. As the slipform equipment is gradually raised, the distance between the movable formwork and the formwork structure of the working compartment decreases, and the thickness of the intermediate partition wall formed by pouring also gradually decreases. This allows the intermediate partition wall to adapt to the water pressure at the corresponding depth, reducing the amount of concrete and steel reinforcement materials used and reducing material costs. The deformable slipform equipment can be adjusted in real time according to the climbing height, which is beneficial to improving the construction efficiency of deep vertical shafts.

[0014] Preferably, in the slipform equipment installation step of S2, a support truss is installed inside the fixed template, and a heightening truss is installed on the top of the support truss and on the top of the multiple work compartment template structures, and the fixed template and the multiple work compartment template structures are fixed by the heightening truss.

[0015] By adopting the above technical solution, the supporting truss reinforces the fixed template with a large degree of bending, and at the same time serves as a connecting component to cooperate with the heightened truss to complete the connection between the fixed template and the template structure of multiple working compartments. This keeps the relative positions of the fixed template and the template structure of multiple working compartments stable, and together they serve as the main frame of the slipform equipment, which helps to improve the overall structural stability of the slipform equipment.

[0016] Preferably, in the slipform equipment installation step of S2, several sets of vertically distributed adjusting cylinders are hingedly installed at the support truss, and the telescopic ends of the adjusting cylinders are hingedly installed on the inside of the movable template. The adjusting cylinders are used to adjust the position and angle of the movable template.

[0017] By adopting the above technical solution, the movable template can be moved under the action of adjusting the extension and retraction of the hydraulic cylinder. At the same time, the tilt angle of the movable template can be changed, which facilitates the formation of the tilted side wall of the partition wall and the formation of the gradient surface structure of the partition wall.

[0018] Preferably, the adjusting template includes an adjusting block and an arc-edge adjusting mold and a straight-edge adjusting mold respectively disposed on both sides of the adjusting block; an adjusting mechanism is installed between the fixed template and the adjusting block and between the movable template and the adjusting block to adjust the position and angle of the movable template between the fixed template and the movable template; the inner side of the straight-edge adjusting mold is sealed tightly against the outer side of the movable template, and the arc-edge adjusting mold is sealed tightly against the outer side of the fixed template; in the movable template displacement step of S4, the adjusting block moves and adjusts under the guidance of the guide beam, the straight-edge adjusting mold slides on the outer side of the movable template, and the arc-edge adjusting mold slides on the outer side of the fixed template, so that the gap between the ends of the movable template and the fixed template is always kept closed.

[0019] By adopting the above technical solution, the adjusting block in the adjusting template is used as a movable part. The angle and position of the movable block are adjusted by the adjusting mechanism. At the same time, in conjunction with the arc-edge adjusting mold and the straight-edge adjusting mold, a sealed connection between the fixed template and the movable template is achieved. While improving the flexibility of the adjusting template, the straight-edge adjusting mold and the outer side of the movable template are kept in close contact, and the arc-edge adjusting mold and the outer side of the fixed template are kept in close contact. This ensures that the gap between the ends of the movable template and the fixed template is always kept closed, which is beneficial to improving the deformation stability and adjustment efficiency of the slipform equipment.

[0020] Preferably, in the slipform equipment installation step of S2, the climbing system includes several climbing rods and several climbing jacks used in conjunction with the climbing rods. The climbing rods are vertically arranged in the construction pit of the deep shaft and distributed circumferentially, and the climbing jacks are installed on the top of the slipform equipment.

[0021] By adopting the above technical solution, and using multiple climbing jacks in conjunction with multiple climbing rods, it is beneficial to stabilize the climbing of the slipform equipment.

[0022] Preferably, a hand chain hoist is slidably connected to the bottom of the heightened truss, and the top of the movable template is fixedly connected to the traction end of the hand chain hoist.

[0023] By adopting the above technical solution, the hand-operated hoist, as a connecting component between the movable template and the heightened truss, can transfer the load of the movable template to the heightened truss, which is beneficial to improving the stability of the movable template. At the same time, the hand-operated hoist can move with the movable template, and the height of the movable template can be adjusted by lifting it, which is beneficial to improving the flexibility of adjusting the movable template.

[0024] Preferably, an operating platform is installed at the bottom of the supporting truss, with the operating platform close to the side wall of the central partition wall and the inner wall of the deep shaft.

[0025] By adopting the above technical solution, an operating platform is installed at the bottom of the supporting truss to facilitate concrete curing, surface finishing, embedded part treatment, and door opening formwork removal.

[0026] Preferably, the operating platform includes booms and an auxiliary plate. When installing the operating platform below the movable template, one pair of booms is fixed to the inner side of the bottom of the movable template, and the other pair of booms is slidably installed at the bottom of the supporting truss.

[0027] By adopting the above technical solution, the hanger, as a connecting component between the movable template and the auxiliary plate, can transfer the load of the movable template to the movable template and the supporting truss, which is beneficial to improving the stability of the auxiliary plate. At the same time, the hanger on the supporting truss can move with the movable template, which is beneficial to improving the flexibility of the operating platform.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. For the construction of climbing formwork equipment for multi-compartment deep vertical shaft structures, the formwork structure corresponding to the water intake pool is composed of fixed formwork, movable formwork, and adjustable formwork. The movable formwork can move relative to the fixed formwork. As the slipform equipment is gradually raised, the distance between the movable formwork and the formwork structure of the working compartment decreases, and the thickness of the intermediate partition wall formed by pouring also gradually decreases. This allows the intermediate partition wall to adapt to the water pressure at the corresponding depth, while reducing the amount of concrete and steel reinforcement materials used, thus reducing material costs. The deformable slipform equipment can be adjusted in real time according to the climbing height, which is beneficial to improving the construction efficiency of deep vertical shafts.

[0030] 2. By setting up an adjusting cylinder, the movable template can be moved under the action of the adjusting cylinder's extension and retraction. At the same time, the tilt angle of the movable template can be changed, which facilitates the formation of the tilted side wall of the partition wall and the formation of the gradient surface structure of the partition wall.

[0031] 3. The adjusting block in the adjusting template is a movable part. The angle and position of the movable block can be adjusted by the adjusting mechanism. At the same time, it works with the arc-edge adjusting mold and the straight-edge adjusting mold to achieve a sealed connection between the fixed template and the movable template. While improving the flexibility of the adjusting template, the straight-edge adjusting mold and the outer side of the movable template are kept in close contact, and the arc-edge adjusting mold and the outer side of the fixed template are kept in close contact. This keeps the gap between the ends of the movable template and the fixed template closed, which helps to improve the deformation stability and adjustment efficiency of the slipform equipment.

[0041] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0042] This application discloses a method for one-time slipform lifting of a large-diameter deep vertical shaft with a gradient surface structure, referring to... Figures 1 to 3 This includes the following steps:

[0043] S1: Eight material unloading pipes are arranged around the construction pit of the deep vertical shaft. Eight 3-ton stable trucks are used to suspend the material unloading pipes, and each material unloading pipe controls a 10-meter diameter working range. A slipform rebar processing plant is set up at the site outside the construction pit of the deep vertical shaft. The finished rebar is transferred from the site by a 25-ton truck crane to the control area of ​​the gantry crane, and then the finished rebar is hoisted to the bottom of the construction pit and tied and fixed.

[0044] S2: After the first section of reinforcing steel is tied, a slipform equipment is installed in the construction pit of the deep shaft. The slipform equipment includes the formwork structure of the inlet pool 3, the formwork structure of multiple working chambers 4, and the climbing system 10 (e.g., Figure 8As shown, the construction gap between the outer side of the template structure of the inlet pool 3 and the inner wall of the deep shaft construction pit, as well as the construction gap between the outer side of the template structure of the working chamber 4 and the inner wall of the deep shaft construction pit, are used to pour and form the main body 1 of the deep shaft. The construction gap between the template structure of the inlet pool 3 and the template structures of multiple working chambers 4 are used to pour and form the central partition wall 2.

[0045] Reference Figure 4 and Figure 5 The template structure of the inlet pool 3 includes a fixed template 5, a movable template 6, and an adjustable template 9. The fixed template 5 extends along the outline of the inner wall of the deep vertical shaft construction pit, the movable template 6 extends along the length of the central partition wall 2, and the adjustable template 9 is used to seal the gap between the movable template 6 and the fixed template 5. The fixed template 5, the movable template 6, and the adjustable template 9 together enclose the template structure of the inlet pool 3 in a circumferentially closed manner.

[0046] A support truss 51 is installed inside the fixed template 5 to reinforce the fixed template 5 which is bent significantly. A heightening truss 7 is installed on top of the support truss 51 and on top of the template structures of the multiple working chambers 4. The support truss 51, in conjunction with the heightening truss 7, connects the fixed template 5 with the template structures of the multiple working chambers 4, ensuring their relative positions remain stable. Together, they form the main frame of the slipform equipment, which helps improve the overall structural stability of the slipform equipment.

[0047] Several sets of vertically distributed adjusting cylinders 52 are hinged at the supporting truss 51. The adjusting cylinders 52 can swing up and down to adjust their orientation. Then, the telescopic ends of the adjusting cylinders 52 are hinged to the inside of the movable template 6. The movable template 6 is moved under the telescopic action of the adjusting cylinders 52. At the same time, the tilt angle of the movable template 6 can be changed to form the inclined side wall of the partition wall 2, which facilitates the formation of the gradient surface structure of the partition wall 2.

[0048] In this embodiment, there are two adjustment templates 9, which are placed at both ends of the fixed template 5. Each adjustment template 9 includes an adjustment block 91 and an arc-edge adjustment mold 93 and a straight-edge adjustment mold 92 respectively disposed on both sides of the adjustment block 91. Furthermore, an adjustment mechanism 8 is installed between the fixed template 5 and the adjustment block 91, and between the movable template 6 and the adjustment block 91, for adjusting the position and angle of the movable template 6 between the fixed template 5 and the movable template 6.

[0049] Reference Figure 6 and Figure 7Specifically, the adjustment mechanism 8 includes two guide beams 82 and two adjustment support rods 81. The two guide beams 82 are respectively installed and fixed at both ends of the adjustment block 91. The two guide beams 82 are located inside the straight-edge adjustment mold 92 and the arc-edge adjustment mold 93, respectively. The two adjustment support rods 81 are respectively hinged to the inside of the two guide beams 82, and the ends of the two adjustment support rods 81 away from the guide beams 82 are arranged in a staggered manner and respectively hinged to the end of the fixed template 5 and the end of the movable template 6. The two guide beams 82 slide along the extension direction of the end of the movable template 6 and the extension direction of the end of the fixed template 5, respectively. The adjustment support rods 81 have telescopic and self-locking functions. In this embodiment, the adjustment support rod 81 includes a bidirectional screw and two threaded sleeves threaded to both ends of the bidirectional screw. The threaded sleeves are hinged to the hinge seats at the guide beams 82. The length of the adjustment support rod 81 can be adjusted by rotating the bidirectional screw. The angle and position of the adjustment block 91 are adjusted by the two sets of adjustment support rods 81 to adapt to the changes in the relative position of the movable template 6 and the fixed template 5. The inner side of the straight-edge adjusting mold 92 is tightly sealed against the outer side of the movable template 6, and the outer side of the arc-edge adjusting mold 93 is tightly sealed against the outer side of the fixed template 5, so that the gap between the ends of the movable template 6 and the fixed template 5 is always kept closed, which helps to improve the deformation stability and adjustment efficiency of the sliding mold equipment.

[0050] Reference Figure 4 and Figure 8 A hand-operated hoist 12 is slidably connected to the bottom of the raised truss 7, and the top of the movable template 6 is fixedly connected to the traction end of the hand-operated hoist 12. The hand-operated hoist 12, as a large-diameter connecting component between the movable template 6 and the raised truss 7, can transfer the load of the movable template 6 to the raised truss 7, which helps improve the stability of the movable template 6. Simultaneously, the hand-operated hoist 12 can move with the movable template 6, and the height of the movable template 6 can be adjusted by lifting it, which improves the flexibility of adjusting the movable template 6.

[0051] To further improve the stability of the movable template 6, an adjusting screw 53 can be installed between the movable template 6 and the supporting truss 51. The adjusting screw 53 has a length adjustment function and a self-locking function.

[0052] An operating platform 11 is installed at the bottom of the supporting truss 51, close to the side wall of the central partition wall 2 and the inner wall of the deep shaft main body 1. The operating platform 11 includes hangers 111 and an auxiliary plate 112. When installing the operating platform 11 below the movable formwork 6, one pair of hangers 111 is fixed to the inner bottom of the movable formwork 6, while the other pair of hangers 111 is slidably installed at the bottom of the supporting truss 51. The auxiliary plate 112 provides a standing area for construction personnel to perform concrete curing, finishing, embedded part processing, and door opening formwork removal.

[0053] In this embodiment, the climbing system 10 includes several climbing rods 101 and several climbing jacks 102 used in conjunction with the climbing rods 101. The climbing rods 101 are vertically arranged in the construction pit of the deep shaft and distributed circumferentially. The climbing jacks 102 are installed on top of the slipform equipment via F-type climbing frames 511. Before installing the climbing rods 101, the steel pipes should be grouted in advance to ensure that the climbing rods 101 have sufficient strength. During the initial installation, ensure that the bottom of the climbing rods 101 is flush with the bottom plate and in perpendicular contact with the bottom plate surface. When installing the slipform equipment, ensure that the template edge line coincides with the design edge line, the slipform climbing rods 101 are vertical, and the entire template is horizontal.

[0054] S3: Concrete is poured into the construction pit of the deep shaft through the discharge pipe to form the first section of the main body of the deep shaft. The concrete should be poured symmetrically, with each pour height controlled between 200 and 300 mm, and efforts should be made to ensure that the concrete surface is at the same horizontal level.

[0055] S4: After the concrete reaches a certain strength, a section of finished steel bar is hoisted down and tied and fixed. Then, the slipform equipment climbs upward under the driving action of the climbing system 10, so that the outer side of the movable template 6 of the slipform equipment is always in close contact with the surface of the poured concrete structure. Then, the position of the movable template 6 is adjusted away from the fixed template 5 to reduce the distance between the movable template 6 and the template structure of the working chamber 4. Then, the position of the adjusting template 9 is adjusted accordingly to fill the gap between the movable template 6 and the fixed template 5, and maintain the sealed state of the template structure of the pre-intake pool 3. In the movable template 6 relocation step, the adjusting block 91 moves and adjusts under the guidance of the guide beam 82. The straight edge adjusting mold 92 slides on the outside of the movable template 6, and the arc edge adjusting mold 93 slides on the outside of the fixed template 5, so that the gap between the ends of the movable template 6 and the fixed template 5 is always kept closed.

[0056] S5: Repeat S3 and S4 to finally form the main body 1 of the deep vertical shaft in the construction pit, and form a middle partition wall 2 structure with gradually changing thickness between the working chamber 4 and the water inlet pool 3. The cross-section of the middle partition wall 2 structure gradually narrows from bottom to top.

[0057] Reference Figure 6 and Figure 7 It should be noted that when the moving distance of the movable template 6 exceeds the adjustment range of the adjustable template 9, the adjustment mechanism 8 can be temporarily removed first, and the end of the support truss 51 and the end of the fixed template 5 can be extended. Then the adjustment mechanism 8 can be reinstalled, and then the position and angle of the adjustment block 91 can be readjusted.

[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
