Embodiment Construction
[0027] The specific embodiments of the present invention are described below so that those skilled in the art can understand the present invention, but it should be clear that the present invention is not limited to the scope of the specific embodiments. For those of ordinary skill in the art, as long as various changes Within the spirit and scope of the present invention defined and determined by the appended claims, these changes are obvious, and all inventions and creations using the concept of the present invention are included in the protection list.
[0028] Such as Figure 1 to Figure 4 , the present invention provides a filter press device for treatment of shield tunneling muck, which includes a plurality of filter presses 2 arranged in the cabin 1 of the shield tunneling machine. The filter press 2 is preferably but not limited to a side bar filter press 2 .
[0029] Each filter press 2 includes a first feed port 3, the first feed port 3 is used to communicate with t...

The invention provides a filter pressing device for shield muck treatment and a muck filter pressing method thereof.The filter pressing device comprises a plurality of filter presses, each filter press comprises a first feeding opening, the first feeding openings communicate with a muck discharging opening of a spiral conveyor, a clear water outlet pipe and a conveying belt are arranged below the filter presses, and a water guide groove is formed below the clear water outlet pipe; a residue discharging channel inclining towards the conveying belt is arranged below the filter press and used for discharging residue soil obtained after filter pressing to the conveying belt, the filter press extrudes and separates water in the residue soil, the separated water flows to the water guiding groove through the clear water outlet pipe, the residue soil obtained after filter pressing enters the conveying belt through the residue discharging channel, and the residue soil enters the conveying belt through the conveying belt. The conveying belt conveys the residue soil subjected to filter pressing to the outside of the cabin of the shield tunneling machine, the filter pressing device can directly conduct solid-liquid separation on the residue soil in a plastic flow state, recycling of the shield residue soil is facilitated, recycling of clean water is achieved, the problem that the shield residue soil is inconvenient to transport is greatly solved, and meanwhile the device is more environmentally friendly.
Description
technical field [0001] The invention relates to the technical field of shield tunneling equipment, in particular to a filter press device and a filter press method for dregs of a shield tunneling machine. Background technique [0002] Due to the advantages of high construction efficiency, wide applicable strata, low cost and relative safety, the shield machine is widely used in urban subway construction. At the same time, due to many reasons such as the addition of bentonite during the tunneling process of the shield machine and the water content of the stratum itself, the muck generated during the construction process contains a lot of water, and some muck is even in a flow-plastic state. At present, the treatment method of shield machine dregs is mainly to directly transport outwards and then carry out centralized accumulation treatment, but because of its high moisture content, the dregs are in a flow-plastic state, which is not convenient for transportation, which leads ...
