Detailed Description
The invention is described in further detail with reference to the figures and specific embodiments.
1. Optimizable point location analysis
The case engineering pipe piece adopts a universal double-faced wedge-shaped ring, as shown in fig. 3, and referring to fig. 1-2, each ring pipe piece is composed of 6 pipe pieces, wherein a top sealing block 1 (F), an adjacent block 2 (L1, L2) and a standard block 3 (B1, B2 and B3), the inner diameter of the ring pipe piece is 5900mm, the outer diameter is 6600mm, the width of the pipe piece is 1200mm, and an embedded sliding groove 2 is embedded in the top sealing block, the adjacent block or the standard block of the ring pipe piece 1.
The arrangement position of the support in the inner space formed by the ring segments is as follows:
a signal machine, a fire fighting pipe, a drain pipe and a plurality of types of cable brackets are arranged at the right side of 40-140 degrees;
an evacuation platform, a lighting lamp, a distribution box and a plurality of cable supports are arranged at 220-332 degrees on the left side.
Because the contact net support is not arranged in each ring, under the condition that the influence is not considered temporarily, the positions of the segment rings without the pre-buried chutes are-40 degrees (namely, the head space) and 140-220 degrees (namely, the bottom space).
When the ring pipe pieces are sequentially spliced into a cylinder with a curvature, the splicing of the ring pipe pieces has sixteen points F1-F16 according to the position of the capping block, and the method is shown in figure 4. Analyzing all point positions, marking the positions of the top blocks by black blocks, representing the area without setting pre-buried chutes by shadow parts, if a segment is completely in the range of the shadow parts, the segment can not set the pre-buried chutes under the point positions, and analyzing results are shown in figure 2
Two points of arches and arch bottoms (F16 and F8) which are relatively unfavorable in engineering are eliminated, four adjacent points of F1, F15, F7 and F9 are eliminated, and 10 optional assembly points are provided. The embedded chute optimization scheme of the ten points is shown in the following table 1, and the table 1 is a point-selectable segment optimization scheme table:
TABLE 1
| Segment assembly point | Optimized segment and position | Segment assembly point | Optimized segment and position |
| F2 | L2 (Top) | F10 | L2 (bottom) |
| F3 | B1 (bottom) | F11 | B1 (Top) |
| F4 | Is free of | F12 | Is free of |
| F5 | B2 (Top) | F13 | B2 (bottom) |
| F6 | L1 (bottom) | F14 | L1 (Top) |
It can be seen that besides two points F4 and F12, the other points are optimized by the embedded sliding grooves of one segment. During typesetting and construction, the positions of the pipe pieces which can be optimized are adopted as far as possible, and the overall optimized proportion is improved. The 8 optimized point positions are divided into four segment rings according to the difference of the optimized embedded chute positions.
And for the pre-buried sliding groove at the contact net, further optimizing according to the typesetting condition according to the rule that one part is arranged at each 7 rings.
2. Segment typesetting according to line and segment information
And (4) inputting basic information of the line and the segment, and typesetting by adopting the optimized point positions as much as possible within the allowable range of the fitting deviation. Since the layout calculation amount is large, the layout calculation is realized by software, as shown in fig. 5, fig. 5 is the setting of layout control parameters.
3. An optimizable segment statistics table is derived as shown in table 2. And (5) making a segment production plan according to the typesetting result, and constructing according to the typesetting result in the construction.
TABLE 2
The above-described embodiments are intended to illustrate the present invention, but not to limit the present invention, and any modifications, equivalents, improvements, etc. made within the spirit of the present invention and the scope of the claims fall within the scope of the present invention.
