Problems solved by technology

[0004] However, in the process of shield tunneling, it is often necessary to enter the soil cabin of the shield tunneling machine for maintenance, inspection or replacement of the knives. In view of these problems, there are roughly two processing methods in the prior art: one is that the staff pass through the protective Entering the pressurized soil cabin of the shield machine for tool inspection or replacement, this method requires high physical fitness of the staff, and the staff need special training before they can work, and this method of const

Embodiment Construction

[0026] refer to figure 1 , figure 2 , image 3 and Figure 4 , the present invention is a soil reinforcement method for realizing the normal pressure opening of a shield machine, characterized in that:

[0027] Include the following steps:

[0028] 1. Stop the excavation of the shield machine, empty the muck in the soil compartment 2 of the shield machine, and seal the soil compartment 2 while discharging soil, and inflate and pressurize the soil compartment 2;

[0029] 1. After the soil discharge in the soil compartment 2 is completed, pour the mixed slurry into the soil compartment 2, and exhaust the soil compartment 2 at the same time until the soil compartment 2 is filled with the mixed slurry;

[0030] , Release the gas pressure in the soil cabin 2, and at the same time replenish the mixed slurry in the soil cabin 2 until the predetermined pressure is reached;

[0031] 1. After the mixed grout is solidified, the soil reinforcement is completed.

[0032] This invent...

Abstract

The invention discloses a soil consolidation method for realizing normal-pressure cabin opening of a shield machine. The method realizes the soil reinforcement by directly injecting mixed grout at a construction part by a shield machine, and solidifying the mixed grout to be plastic concretion with low intensity and small cohesive force on a construction face so as to finally realize normal-pressure cabin opening. The method can avoid the inconveniences caused by the soil reinforcement realized by constructing downwardly from ground or the soil reinforcement realized by injecting grout to form set cement with high intensity and large cohesive force, is favourable for the reduction of the construction cost effectively. The method is used in the field of engineering construction.

Description

technical field [0001] The invention relates to a soil reinforcement method, in particular to a soil reinforcement method for realizing normal-pressure opening of a shield machine. Background technique [0002] The shield machine is usually also called the shield tunnel boring machine, which is a kind of special engineering machinery used for tunnel boring. Excavating and cutting soil, transporting soil muck, assembling tunnel lining, measuring and guiding deviation correction, etc., and it is necessary to carry out "tailor-made" design and manufacture according to different geological conditions. The reliability requirements are extremely high. Shield tunneling machines have been widely used in subways, Railway, highway, municipal, hydropower and other tunnel projects. [0003] Tunnel construction with shield machine has the advantages of high degree of automation, saving manpower, fast construction speed, one-time hole formation, not affected by climate, control of ground...
