Abstract

The invention discloses a subsurface tunnel reverse shield receiving method. The subsurface tunnel reverse shield receiving method comprises the following steps that firstly, a subsurface tunnel is constructed in front of the preset receiving position of a shield; secondly, soil of the shield receiving section is reinforced; thirdly, after a shield tunneling machine tunnels to the shield receiving position, cover removing construction is conducted on the closed working face of the subsurface tunnel; fourthly, a section is excavated towards the shield receiving position along the subsurface tunnel, and excavating is conducted until a shield cutter disk is exposed out completely and part of a shield shell is exposed out; fifthly, end sealing is conducted on a tunnel face between an underground excavation primary support and the shield shell; sixthly, the interior of the subsurface tunnel is reinforced; seventhly, components, except the shield shell, of the shield tunneling machine are dismounted in the tunnel and conveyed out; eighthly, waterproof construction in the subsurface tunnel and waterproof construction in the shield shell are conducted, and then remaining secondary lining construction is conducted. The subsurface tunnel reverse shield receiving method solves the technical problems existing in disassembling, dismounting and conveying of the shield tunneling machine in a cave at the section without the condition of hoisting receiving.

Description

technical field [0001] The invention belongs to the technical field of shield tunneling, and in particular relates to a receiving method for back-excavating shield tunnels in buried tunnels. Background technique [0002] The Shield Method is a fully mechanized construction method in underground excavation construction. It propels the shield machine in the ground, and supports the surrounding rock through the shield casing and segments to prevent collapse into the tunnel. At the same time, a cutting device is used to excavate the soil in front of the excavation face, and it is transported out of the hole by an excavation machine, and it is jacked in the rear by a jack, and the prefabricated pieces are assembled to form a mechanized construction method of the tunnel structure. [0003] Compared with traditional construction methods, shield tunneling method is widely used in rail transit construction because of its high safety, fast construction speed and low cost. In traditio...
