Embodiment Construction

[0017] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0018] In the urban tunnel and subway industry, the shield construction method is a special method for constructing tunnels in soft ground. During the shield construction process, a large amount of shield muck will be produced, and a large amount of shield muck contains gravel and larger particles. , a large amount of shield muck is difficult to dispose of. In order to solve the problem of shield muck disposal, such as Figure 1 to Figure 2 Shown, the present invention has preferred a kind of shield dregs harmless treatment method, such as figure 1 As shown, the specific steps are as follows:

[0019] 1. The shield mud generated during rail transit construction is sent to the slurry separation...

Abstract

The invention discloses an innocent treatment method for shield tunneling residue soil. The innocent treatment method comprises the following steps: hydraulically flushing the shield tunneling residue soil by virtue of residue slurry separation equipment so as to separate mud and cleaned gravel particulate matters; processing mud by virtue of a mud treatment process so as to form muddy water and mud blocks; and purifying the muddy water by virtue of a muddy water treatment system. The gravel particulate matters formed after the shield tunneling residue soil is processed can be used as a concrete aggregate, so that the waste is recycled, and the economic value is increased; the mud blocks with low sand content and moisture content can be used as a brick-making material, so that a made brick is good in quality; and the muddy water can be reused after being treated. The matters formed after the shield tunneling residue soil is processed are valuable, the gravel particulate matters can be used as the concrete aggregate, the made brick is good in quality, and the water can be reused, so that the reclamation, reduction and innocent treatment of the shield tunneling residue soil can be realized, the land consumption is reduced, and the natural environment is protected.

Description

technical field [0001] The invention relates to the field of shield machine dregs treatment, in particular to a harmless treatment method for shield machine dregs. Background technique [0002] With the vigorous construction of cities, the development of urban-rural integration, and the construction of urban tunnels and subways, a large amount of shield muck, construction waste, and shield muck production have increased significantly during the construction process. The number and storage capacity of the existing treatment facilities can no longer meet the requirements for the disposal of shield dregs, construction waste, and shield dregs at the present stage, and the phenomenon of illegal spoils still exists. In order to solve the sharp increase in the output of urban shield muck, the number and storage capacity of existing treatment facilities are insufficient, in order to fully implement the scientific development concept, and work together to build a "two-type leading ci...
