Embodiment Construction

[0044] The specific implementation manner of the present invention will be described below with reference to the accompanying drawings. Such as Figure 1 to Figure 14 Shown: A construction method for rapid reception and translation of the shield machine in the cavern, which is carried out in sequence according to the following steps:

[0045] Step 1: Build the hoisting shaft 1 of the right line and the receiving chamber 2 of the left line, the two are connected through the transverse passage 3, and the receiving chamber 2 of the left line is also connected with the segment tunnel 4, and the receiving chamber 2 of the left line The excavation part on one side is canceled, and the excavation part on the right side is extended at the same time, so that the cross-section of the cross passage 3 and the receiving chamber 2 on the left line forms an L-shape.

[0046] Step 2: Determine the elevation data of the shield receiving floor according to the elevation of the tunnel axis and ...

Abstract

The invention discloses a rapid receiving transverse moving construction method of a shield tunneling machine in a chamber. Firstly, a right line lifting vertical shaft and a left line receiving chamber are built and are in communication through a transverse channel, the left line receiving chamber communicates with a pipe piece tunnel, an underground excavation part on one side of the left line receiving chamber is omitted, meanwhile, a right side underground excavation part is extended in an equal-length manner, and the transverse channel and the cross section of the left line receiving chamber form the L shape. Through adjusting the layout and structure manner of the receiving chamber of the shield tunneling machine, shield body whole rotating transverse moving lifting out can be achieved, the dismantling separation condition of the shield tunneling machine in the chamber can be avoided, the dismantling workloads can be reduced, the shield body transverse moving lifting-out time isshortened, through setting of two receiving platform applications, receiving work of the shield body and the later matched trolley can be synchronously carried out, the shield machine whole receivingwork flow and link are compressed, and work construction time is shortened.

Description

technical field [0001] The invention relates to the field of shield tunneling construction, in particular to a fast receiving translation construction method of a shield tunneling machine in a cavern. Background technique [0002] With the continuous development of shield tunneling technology, the proportion of shield tunneling in construction is also increasing. The launch and reception of shield tunneling are two important links in shield tunneling construction. Usually, the launch and reception of shield tunneling are completed by using the completed station end or the launch and reception shaft of shield tunneling. However, in urban subways, limited by land acquisition and tight urban land use, the reception of the shield machine will also adopt the method of starting and receiving in the cavern. [0003] Shield construction is generally divided into two lines on the left and right. In order to realize the reception of the shield machine, firstly, a shield hoisting shaf...
