Embodiment Construction

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0036] The core of the present invention is to provide a TBM cutter head, which can reduce the difficulty of slag removal of the TBM in the tunneling of the front shaft method. Another core of the present invention is to provide a construction method for an inclined shaft, which is less difficult to extract slag.

[0037] It should be noted that when an element is referred to as "fixing" another element, it may be directly on the other element or there may be ...

Abstract

The invention discloses a TBM cutter head and an inclined shaft construction method. The TBM cutter head comprises a cutter head body, wherein the cutter head body comprises a panel, a back plate andan annular side plate; the panel and the back plate are sequentially arranged from front to back in the axial direction; the edge of the panel and the edge of the back plate are connected to the sideplate; a front slag discharging channel is arranged between the panel and the back plate; a first slag inlet is formed in the panel in a penetrating mode; a first bucket is correspondingly arranged onthe first slag inlet; the middle of the panel penetrates through a panel through hole; the first slag inlet communicates with the panel through hole through the front slag discharging channel; and the panel is gradually inclined towards the rear part in the axial direction from the panel through hole to the edge. Based on the arrangement of the front slag discharging channel and the panel throughhole in the TBM cutter head, a middle pilot tunnel which is excavated in a soil body in advance can be used as a slag discharging channel for slag discharging, slag conveying structures such as conveying equipment for uploading slag soil do not need to be additionally arranged in a TBM, and the slag discharging operation is greatly facilitated.

Description

technical field [0001] The invention relates to the technical field of tunneling equipment, in particular to a TBM cutter head and a construction method for an inclined shaft. Background technique [0002] In the fields of coal mines and water conservancy projects, many oblique tunnels with large inclination angles need to be built, especially in the field of diversion tunnel engineering for pumped storage power stations, the demand for tunnels with large inclination angles is increasing day by day. At present, TBM is used to excavate such large-slope inclined shaft tunnels, and most of them are excavated by the front shaft method. [0003] The front shaft method means that the TBM tunnels obliquely from top to bottom, but this type of construction method is more difficult to remove slag such as slag removal from the cutter head of the roadheader, which affects its scope of application. [0004] Therefore, how to reduce the difficulty of slagging out of the TBM in the tunne...
