Problems solved by technology

As the technology continues to mature, the shield tunneling method is generally used for tunnel excavation. The existing air shafts generally take into account the functions of the shield launching shaft, receiving shaft or construction shaft. In order to meet the function of shield tunneling or launching, The wind shaft project is large in scale and deep in depth. If the wind shaft is not reinforced in place, it will easily cause the subsequent wall to loosen or collapse, which not only poses certain safety hazards, but also increases the difficulty of construction.

Embodiment Construction

[0057] The present invention is a control construction method of ultra-deep wind shaft reinforcement control, comprising the following steps:

[0058] 1) Construction preparation

[0059] a. First, measure and set out the air shaft, measure the elevation, length and width of the air shaft, perform recheck measurement, and measure the verticality of each side of the air shaft, check with the design requirements, and use a drilling machine for the excess side Drill flat to ensure that the angle between each side matches the design requirements;

[0060] b. Then level the bottom surface and each side of the air shaft, remove the exposed stones on the bottom surface and sides, smooth it with mortar, use mortar to level the uneven bottom surface or side, and then use a tamping machine to level the air shaft The bottom and sides of the soil are compacted to compact the clay on the bottom or sides;

[0061] c. Then set up scaffolding in the air shaft, and fix the scaffolding with t...

Abstract

The invention discloses a method for controlling ultra-deep air shaft reinforcing construction. The method comprises the following steps: (1) construction preparation; (2) waterproof layer construction; (3) first-layer side plate supporting; (4) reinforcement cage laying; (5) second-layer side plate supporting; (6) reinforcing device construction; (7) concrete construction; and (8) completion acceptance. The reinforcing construction method can meet reinforcing construction of ultra-deep air shafts of different depths, using safety of the air shafts is improved greatly, collapse caused by the long time is prevented, the construction steps are simple and convenient, compared with existing air shafts, the reinforcing effect is better, and influences on the whole air shafts during shield construction are reduced.

Description

technical field [0001] The invention relates to a control construction method for super-deep air shaft reinforcement control. Background technique [0002] During the construction of underground tunnels, it is generally necessary to set up an air shaft in the middle of the construction section to meet the needs of air supply in the tunnel, and at the same time to meet the load-bearing weight of the shield machine during shield construction. As the technology continues to mature, the shield tunneling method is generally used for tunnel excavation. The existing air shafts generally take into account the functions of the shield launching shaft, receiving shaft or construction shaft. In order to meet the function of shield tunneling or launching, The air shaft project is large in scale and deep in depth. Inadequate reinforcement of the air shaft often easily leads to loosening or collapse of the subsequent walls, which not only poses certain safety hazards, but also increases th...
