Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] The present invention mainly relates to a construction method for dismantling old tunnel segments and tunnel diameter expansion by using a tunnel expanding machine 10, see figure 1 and figure 2 As shown, the tunnel enlarging machine mainly includes: an inner shell 107 and an outer shell 106, between the inner shell 107 and the outer shell 106, a cutting cutter head 101 is arranged at the front end of the tunnel enlarging machine 10, and the inner shell A segment removal machine 104 is arranged at the front end of the inner side of the body 107, a segment assembly machine 105 is arranged at the rear of the inner housing 107, and a jack 102 is arranged at the tail of the tunnel expanding machine 10. The tunnel expanding machine 10 advances through the side of the new tunnel segment 31 supported by the jack 102 . The diameter of the inne...

Abstract

The invention provides a construction method for old tunnel segment detaching and tunnel expanding. The method includes the following steps that an originating terminal of a tunnel expanding machine is set up; the tunnel expanding machine is placed on the originating terminal and originates; the tunnel expanding machine is normally propelled, old tunnel segments are detached through a segment dismantling machine of the tunnel expanding machine, and meanwhile novel tunnel segments are spliced through a segment splicing machine of the tunnel expanding machine; a receiving terminal of the tunnel expanding machine is set up; the tunnel expanding machine enters the receiving terminal. The construction method has the advantages that according to the construction technology, a pipeline tunnel structure in site is dismantled and replaced, the diameter of an original tunnel is expanded, and the construction method is high in automation degree, safe and reliable.

Description

technical field [0001] The invention relates to a tunnel construction method, in particular to a construction method for removing old tunnel segments and expanding the diameter of the tunnel. Background technique [0002] In recent years, municipal pipeline tunnels, rail transit tunnels and other types of tunnels have developed rapidly in recent years. So many various types of tunnel projects determine that we will gradually transition from the current period of large-scale construction and development of tunnel projects to the period of repair, maintenance, reconstruction and expansion of various types of tunnels. Generally speaking, tunnel projects are relatively focused on new construction, and there is insufficient preparation and consideration for the maintenance of old tunnels or the need to expand and excavate tunnels due to increased traffic demand. Reconstruction and expansion tunnels are limited by the section space of the original tunnel, and the longitudinal and...
