Description

Technical Field

[0001] The present invention relates to the technical field of inclined shaft lining and grouting construction, in particular to self-propelled creeping inclined shaft full-process integrated construction equipment and a construction method. Background Art

[0002] During inclined shaft construction, lining trolleys are essential equipment for secondary lining operations, primarily used to apply concrete to the shaft's interior walls. Currently, concrete for high- and steep-slope inclined shafts is typically poured in sections using full-frame support frames or using slipforms. Full-frame support frame pouring has been largely eliminated in recent years due to slow construction progress, significant safety hazards, and the high volume and difficulty of recyclable materials. While slipform construction significantly outperforms full-frame support frame pouring in terms of construction progress and safety, it also presents challenges such as large over-excavation and backfill in the upper bend of the inclined shaft, high safety risks associated with slipform installation and lowering, a failure to adequately consider concrete pouring in the upper bend, high risks associated with installing and removing the sealing platform for the upper bend, and the need for a separate grouting platform after concrete construction is completed. Furthermore, slipform construction for inclined shafts cannot be efficiently integrated with other processes. While the advantages of the slipform system can be realized for long inclined shafts, the advantages of slipform technology are less pronounced for shorter, steeply sloped inclined shafts.

After the locking claws 42 reach the predetermined position, the positive and negative triangular claws 423 need to be manually moved to engage the ends of the positive and negative triangular claws 423 with the bayonet holes on the upper surface of the box-shaped track 44. In this embodiment, the positive and negative triangular claws 423 are provided with a column to facilitate the rotation of the positive and negative triangular claws 423.

This ensures that the fully integrated construction equipment remains stable during the pouring process and prevents tilting.

[0032] When the pouring operation is completed, the four short diagonal braces 511 are retracted and the large rear diagonal brace 512 is removed; and when the self-propelled peristaltic inclined shaft full-process integrated construction equipment moves to the next pouring position, the large rear diagonal brace 512 is re-anchored to ensure that it still has good stability in the new position.

Between the vertical support columns, a number of horizontal and vertical connecting rods are installed. These connecting rods are arranged in parallel and evenly distributed in 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.

[0034] Based on Example 1, this embodiment provides a construction method for an underground cavern group during the construction period, which is applied to the above-mentioned self-propelled peristaltic inclined shaft full-process integrated construction equipment, including the following steps: Step 1) Casting of the straight section of the inclined shaft: At the bottom of the inclined shaft, a self-propelled peristaltic inclined shaft full-process integrated construction equipment and an anti-overturning device 5 are installed. After installation, when the equipment is in a stationary state, the three sets of locking claws 42 are locked, and the ends of the positive and negative triangular claws 423 engage with the upper surface of the box track 44, entering the pouring state. The formwork 3 is connected to the bottom of the outer frame 22 through the screw jack 61, the demoulding cylinder 62, the hanger base 341 and the bottom form hanger 68. The formwork 3 is moved to the predetermined position through the screw jack 61 and the demoulding cylinder 62. After the assembly, positioning and debugging of the formwork 3 are completed, concrete pouring is carried out. 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 to the right position, the lifting cylinder 63 is used to adjust the position of the outer frame 22 along the height direction of the tunnel. After the position of the outer frame 22 along the height direction of the tunnel is adjusted to the right position, the horizontal hydraulic jack 65 is used to slightly adjust the inner frame 21 to adjust the lateral position of the outer frame 22. Finally, when the horizontal and vertical positions of the outer frame 22 are adjusted, the vertical hydraulic jack 66 starts working to bear 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 removed, and the demoulding cylinders 62 of the top form 31, the left form 32, and the right form 33 are recovered. The demoulding cylinder 62, the bottom form hanger 68, and the anti-overturning device 5 are removed; Step 2) Equipment promotion: After pouring is completed, the first set of locking claws 42 are 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 are locked, the second and third sets of locking claws 42 are unlocked, and 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 pouring state again and enters the next construction cycle until the construction of the straight section of the inclined shaft is completed; Step 3) Casting 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; a scaffolding is set up between the rear needle beam 13 and the inclined shaft wall as a working platform, one end of the scaffolding main beam is simply supported on the 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 built, the secondary beam and the full-floor support frame are built to form a formwork support frame. After the working platform and the formwork support frame are built, the upper bend section is poured; Step 4) Grouting construction of the straight section of the inclined shaft: After the pouring of the upper bend section is completed, the scaffolding is removed, and the equipment returns to the grouting starting position of the straight section of the inclined shaft, the front needle beam 11 and the middle needle beam 12 are reconnected, the three groups of locking claws 42 are locked, and the equipment enters the grouting state. The operating personnel carry out grouting and hole making, grouting and post-grouting inspection on the platform built on the middle needle beam 12; after completing a section of grouting, the first group of locking claws 42 are released, the second and third groups of locking claws 42 are locked, and the equipment is driven by two groups of driving cylinders to move forward along the box track 44 to the next grouting section; after reaching the new grouting section, the front first group of locking claws 42 are locked, the second and third groups of locking claws 42 are unlocked, and the hydraulic cylinder 67 is retracted. After the hydraulic cylinder 67 is retracted, the second and third groups 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.
