Embodiment Construction

[0044] Specific embodiments of the present invention will be described below with reference to the accompanying drawings. like Figure 1 to Figure 14 Shown: A construction method for rapid reception and translation of shield machines in a cavern, which is carried out in sequence according to the following steps:

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

[0046] Step 2: According to the elevation of the tunnel axis and the structure size of the receiving platform of the shield machine, determine the elevation ...

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 construction, in particular to a construction method for rapid reception and translation of a shield machine in a cavern. Background technique [0002] With the continuous development of shield construction technology, the proportion of shield in construction is also increasing. The origin and reception of the shield are two important links in the construction of the shield. Usually, the origin and reception of the shield are completed by using the completed station terminal or the receiving well for the origin of the shield. However, in the urban subway, limited by land acquisition and tight urban land, the receiving of the shield machine will also use the method of originating and receiving from the cavern. [0003] Shield construction is generally divided into two lines, left and right. In order to achieve shield reception, first, a shield hoisting shaft is constructed above the position where one line o...
