Embodiment Construction

[0021] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0022] Such as figure 1 , as shown in 2, the simulated turntable used for general wedge-shaped segment assembly point selection of the present invention includes an assembly point disk 1, an assembly situation disk 2 of the previous ring, an assembly situation disk 3 of the ring to be spliced ​​and a next ring that can be assembled. Assemble the situation plate 4.

[0023] The assembly point plate 1, the upper ring assembled state plate 2, the to-be-assembled ring assembled state plate 3 and the next ring assembled state plate 4 four discs with different diameters are concentrically layered through the single-head thin bolt 5 Wear them together, put ring gaskets 7 between the discs, and fix the tops of the single-head bolts 5 with nuts 6, thereby making a multi-circle concentric turntable that can rotate at will. Use the assembly point plate 1...

Abstract

The invention relates to a simulation rotating disc for universal wedge-shaped segment splicing point position selection, which comprises a splicing point position disc, a previous ring splicing condition disc, a to-be-spliced ring splicing condition disc and a next ring splicing condition disc, the assembling point position disc, the previous ring assembling condition disc, the to-be-assembled ring assembling condition disc and the next ring assembling condition disc are discs with different diameters and are concentrically penetrated together in a layered mode through the single-head thin bolts, the circular ring gaskets are placed between the discs, the tops of the single-head bolts are fixed through the nuts, and therefore the multi-circle concentric rotating disc capable of rotating at will is manufactured. According to the method, the splicing condition of each point position of the to-be-spliced ring segment can be conveniently and intuitively simulated and analyzed, and the condition that the splicing point position can be selected for the next ring segment is pre-judged, so that the optimal splicing point position is quickly selected. The method is applied to shield tunnel universal wedge-shaped duct piece splicing construction, manufacturing is easy, operation is convenient, and the duct piece splicing work efficiency can be improved.

Description

technical field [0001] The invention relates to an auxiliary device for selecting the assembling point of a segment, in particular to a simulated turntable for selecting the assembling point of a general wedge-shaped segment in a shield tunnel. Background technique [0002] With the rapid development of urban construction, more and more areas have adopted general-purpose wedge segments in the construction of shield tunnels. Compared with the traditional "straight line + turning ring" segment form, the universal wedge segment can choose the assembly point of the segment according to the construction needs, so that the wedge amount is distributed in different positions, so as to realize tunnel turning and slope changes more flexibly Isolinear changes. In actual construction, segment assembly needs to select the assembly point in consideration of shield tail clearance, segment attitude, jack travel difference, shield attitude, tunnel line shape, etc. There are 8 to 9 kinds of...
