Description

Technical Field

[0001] This invention relates to the field of inclined shaft lining and grouting construction technology, and in particular to a self-propelled peristaltic inclined shaft integrated construction equipment and construction method. Background Technology

[0002] In the construction of inclined shafts, lining trolleys are essential equipment for secondary lining operations, primarily used for concrete lining of the inner wall of the inclined shaft. Currently, concrete for steep inclined shafts is typically constructed using either full-span support frames for segmented pouring or slipform construction. Full-span support frame segmented pouring has been largely phased out in recent years due to its slow construction progress, significant safety hazards, large consumption of reusable materials, and difficulties in material turnover. Slipform construction offers significant advantages over full-span support frame segmented pouring in terms of construction progress and safety, but it also presents challenges such as large over-excavation and backfilling volumes in the upper curved section of the inclined shaft, high safety risks during slipform installation and lowering, failure to simultaneously handle concrete pouring in the upper curved section, high risks associated with the installation and dismantling of the sealing platform in the upper curved section, and the need for a separate grouting platform after concrete construction. Furthermore, slipform construction for inclined shaft concrete cannot be efficiently integrated with other processes. While slipform systems offer advantages for long-distance inclined shafts, their advantages are no longer significant for shorter, steep inclined shafts.

[0003] Therefore, this invention proposes a self-propelled peristaltic inclined shaft integrated construction equipment and construction method. Summary of the Invention

The top support frame 521 includes vertical support columns, horizontal connecting rods, and vertical connecting rods. The vertical support columns are symmetrically arranged on both sides of the horizontal beam on the front pin beam 11 and fixed by bottom connecting components to ensure that the columns can withstand vertical loads and provide stable support. Between the vertical support columns, several horizontal and vertical connecting rods are installed. These connecting rods are arranged in parallel and evenly distributed along the horizontal and vertical directions to strengthen the connection between the left and right columns, forming a stable frame structure to effectively resist lateral deformation and shear force. The side support frame 522 has the same structure as the top support frame 521. The vertical support columns are horizontally arranged on both sides of the longitudinal beam on the front pin beam 11 and fixed by bottom connecting components to ensure that the columns can withstand horizontal loads and provide stable support. like Figure 14 As shown, the rear stabilizing mechanism 53 includes a top support frame 521 and a side support frame 522.

The formwork 3 is connected to the bottom of the outer frame 22 via the screw jack 61, demolding cylinder 62, hanger base 341, and bottom formwork hanger 68. The formwork 3 is then moved to the predetermined position via the screw jack 61 and demolding cylinder 62. After the assembly, positioning, and debugging of the formwork 3 are completed, concrete is poured. Specifically, when the pouring position is reached, the lateral position of the inner frame 21 is adjusted by the translation cylinder 64. After the lateral position of the inner frame 21 is adjusted, the position of the outer frame 22 along the tunnel height direction is adjusted by the lifting cylinder 63. After the position of the outer frame 22 along the tunnel height direction is adjusted, the inner frame 21 is adjusted slightly by the horizontal hydraulic jack 65 to adjust the lateral position of the outer frame 22. Finally, after the outer frame 22 is adjusted horizontally and along the tunnel height, the vertical hydraulic jack 66 starts to work and bears part of the force of the outer frame 22; after the pouring is completed, the formwork 3 is removed in sequence. First, the screw jack 61 is disassembled, and the demolding cylinders 62 of the top formwork 31, the left formwork 32, and the right formwork 33 are recovered. The demolding cylinders 62, the bottom formwork hanger 68, and the anti-overturning device 5 are disassembled. Step 2) Equipment advancement: After the pouring is completed, the first set of locking claws 42 is released, the second and third sets of locking claws 42 are locked, and the equipment is driven by two sets of driving cylinders to move forward along the box track 44 to the next working section; after reaching the new position, the first set of locking claws 42 is locked, the second and third sets of locking claws 42 are unlocked, the hydraulic cylinder 67 is retracted, and after the hydraulic cylinder 67 is retracted, the second and third sets of locking claws 42 are locked, and the equipment enters the pouring state again and enters the next construction cycle until the straight section of the inclined shaft is completed. Step 3) Construction of the upper curved section of the inclined shaft: When the equipment reaches the upper bend section, the front needle beam 11, the middle needle beam 12 and the beam frame 2 are removed, leaving only the rear needle beam 13 and the walking system 4. Scaffolding is erected between the rear needle beam 13 and the inclined shaft wall as a working platform. One end of the main beam of the scaffolding is simply supported on the pre-reserved concrete groove of the inclined shaft wall, and the other end is fixed on the rear needle beam 13. After the main beam is erected, the secondary beam and the full-span support frame are erected to form the formwork support frame. After the working platform and the formwork support frame are erected, the upper bend section is poured. Step 4) Grouting construction of the straight section of the inclined shaft: After the upper curved section is poured, the scaffolding is removed, and the equipment is returned to the grouting start position of the straight section of the inclined shaft. The front needle beam 11 and the middle needle beam 12 are reconnected, and the three sets of locking claws 42 are locked. The equipment enters the grouting state, and the operators perform grouting hole drilling, grouting, and post-grouting inspection on the platform built on the middle needle beam 12. After completing a grouting section, the first set of locking claws 42 is released, and the second and third sets of locking claws 42 are locked. The equipment is driven to move forward along the box track 44 to the next grouting section by two sets of drive cylinders. After reaching the new grouting section, the first set of locking claws 42 is locked, and the second and third sets of locking claws 42 are unlocked. The hydraulic cylinder 67 is retracted. After the hydraulic cylinder 67 is retracted, the second and third sets of locking claws 42 are locked, and the equipment enters the grouting state again and enters the next construction cycle until the construction of the straight section of the inclined shaft is completed.
