Translation construction structure of shield machine, and translation method

Abstract

The invention discloses a translation construction structure of a shield machine, and a translation method. The translation construction structure of the shield machine comprises two guide rails arranged at the bottom of a tunnel translation construction section, a plurality of rolling wheels with the same mounting height and a driving device for pushing the shield which needs to be translated to move forwards; the plurality of rolling wheels are arranged on a shield body of the shield machine; a pair of rolling wheels are arranged on each of a front shield and a tail shield of the shield machine; at least two pairs of rolling wheels are arranged on a middle shield of the shield machine; the driving device comprises a thrust mechanism and a counter-force mechanism. The translation method comprises the following steps: 1, determining the pavement length of the guide rails; 2, paving the guide rails; 3, translating the shield machine. The rolling wheels are directly fixed on the shield machine, a bracket trolley is replaced, the height required by translation of the shield machine is reduced, secondary construction of the existing tunnel is avoided, the problem that the supporting strength is reduced caused by change of a supporting structure is solved, the problem of translation of the shield machine is solved, and the construction process is simple and high in speed.

Description

technical field [0001] The invention belongs to the technical field of shield machine construction, and in particular relates to a shield machine translational construction structure and translation method. Background technique [0002] The earth pressure balance shield machine is referred to as the shield machine. It is a common tunnel boring machine for full-section excavation in soft rock or soil surrounding rock. During the excavation process of the shield machine, the shield machine passes or replaces the work. The shield machine needs to be translated during tunneling, and the tunnel section where the shield machine is translated becomes the translation construction section, such as figure 1 As shown, the translation of the existing shield machine is to translate the shield machine through the bracket trolley 11, but when the translation is carried out in the underground excavation tunnel, the tunnel height h of some sections of the tunnel is less than Working height ...

Problems solved by technology

[0002]Earth pressure balance shield machine, referred to as shield machine, is a common tunnel boring machine for full-section excavation in soft rock or soil surrounding rock. During the excavation process of the tunnel, the shield machine needs to be translated when the shield machine passes the station or replaces the working tunnel, and the tunnel section where the shield machine is translated becomes the translation construction section, such as Figure 1 shows that the translation of the existing shield machine is to translate the shield machine through the bracket trolley 11, However, when translation is carried out in the underground excavation tunnel, due to the technical method of the underground excavation tunnel, the tunnel height h of some sections of the tunnel is less than the working height H1 when using the carriage trolley 11, the working height is the distance between the top of the shield machine and the bottom of the tunnel when the shield machine is moving in translation. At this time, if the carriage trolley 11 is to be used to move the shield machine in translation, it is necessary to expand the tunnel segment with the tunnel height h. During the chiseling process, not only time-consuming and labor-intensive seriously affect the construction progress, but also affect the existing support of the tunnel, reduce the stability and strength of the tunnel support, and cause great difficulties to the translation of the shield machine
