[0047] Embodiment 1: This embodiment is an automatic acquisition method for segment opening amount during the shield construction stage, which specifically includes the following steps:

[0048] S100. Obtain the width e and wedge amount p of the segments in the section corresponding to the m-th ring of segments, as well as the number q of assembly positions and the assembly position i corresponding to the m-th ring.

[0049] S200. Respectively obtain the shield machine travel corresponding to the upper, lower, left, and right four feature points on the shield machine when advancing to the (m - 1)-th and m-th rings of segments, and the cylinder travel corresponding to each feature point.

[0050] In this embodiment, travel sensors are installed at the upper, lower, left, and right four feature points on a cross-section of the middle shield of the shield machine. Through the travel sensors at the upper, lower, left, and right four feature points, the shield machine travel corresponding to the four feature points is recorded in real time.

[0051] S300. Based on the width e and wedge amount p, as well as the number q of assembly positions and the assembly position i corresponding to the m-th ring, calculate the segment width corresponding to each feature point on the m-th ring of segments.

[0052] In this embodiment, the taper of the universal segment is p, there are q assembly points in total, and the width of the segment is e. Taking the segment with a conventional diameter of 6m as an example, the widest part is located at block B2, and the narrowest part is located at block F. The width difference between the two is the taper. As the assembly points of the segments are different, the widths of the segments in the up, down, left, and right directions are also different. When the segment is assembled at point i, the widths of the segments corresponding to the four characteristic points of the taper in the up, down, left, and right directions of the tunnel are as follows:

[0053]

[0054] Among them, g ms is the width of the segment corresponding to the upper characteristic point when the assembly point of the m-th ring of segments is at point i, g mx is the width of the segment corresponding to the lower characteristic point when the assembly point of the m-th ring of segments is at point i, g mz is the width of the segment corresponding to the left characteristic point when the assembly point of the m-th ring of segments is at point i, g my is the width of the segment corresponding to the right characteristic point when the assembly point of the m-th ring of segments is at point i.

[0055] S400. Based on the shield machine travel and cylinder travel corresponding to each characteristic point when advancing to the (m - 1)-th and m-th rings of segments, determine the segment travel corresponding to each characteristic point at the front end of the (m - 1)-th and m-th rings of segments.

[0056] S m = W m - x - a m

[0057] X m = U m - x - b m

[0058] Z m = Q m - x - c m

[0059] Y m = V m - x - d m

[0060] Among them, S m is the segment travel corresponding to the upper characteristic point at the front end of the m-th ring of segments, X m is the segment travel corresponding to the lower characteristic point at the front end of the m-th ring of segments, Z m is the segment travel corresponding to the left characteristic point at the front end of the m-th ring of segments, Y m is the segment travel corresponding to the right characteristic point at the front end of the m-th ring of segments, W m is the shield machine travel corresponding to the upper characteristic point when advancing to the m-th ring of segments, U m is the shield machine travel corresponding to the lower characteristic point when advancing to the m-th ring of segments, Qm To advance to the shield machine travel corresponding to the left feature point of the m-th segment ring, V m To advance to the shield machine travel corresponding to the right feature point of the m-th segment ring, x is the distance between the travel sensor and the front plane of the oil cylinder, a m To advance to the oil cylinder travel corresponding to the upper feature point of the m-th segment ring, b m To advance to the oil cylinder travel corresponding to the lower feature point of the m-th segment ring, c m To advance to the oil cylinder travel corresponding to the left feature point of the m-th segment ring, d m The oil cylinder travel to advance to the right feature point of the m-th segment ring.

[0061] S500. Determine the segment opening amount corresponding to each feature point between the m-th segment ring and the (m - 1)-th segment ring based on the segment travel corresponding to each feature point at the front end of the (m - 1)-th and m-th segment rings, and the segment width corresponding to each feature point on the m-th segment ring.

[0062]

[0063] The following is illustrated with a specific example:

[0064] Travel sensors are installed at four feature points, namely the upper, lower, left, and right, of the shield machine in a certain section. The segment width of this section is 1.2 m, the outer diameter of the segment is 6.2 m, the segment taper is 40 mm, and it is divided into 12 erection positions. After the 200th ring is advanced, the travel sensors at the four feature points of the upper, lower, left, and right are 246.183 m, 243.225 m, 247.636 m, and 244.512 m respectively, and the oil cylinder travels at the four feature points of the upper, lower, left, and right are 1793 mm, 1785 mm, 1798 mm, and 1781 mm respectively. The erection position of this segment ring is position 11.

[0065] After the 201st ring is advanced, the travel sensors at the four feature points of the upper, lower, left, and right are 247.426 m, 244.500 m, 248.899 m, and 245.749 m respectively, and the oil cylinder travels at the four feature points of the upper, lower, left, and right are 1823 mm, 1850 mm, 1836 mm, and 1831 mm respectively. The erection position of this segment ring is position 3.

[0066] Substitute the above shield parameter information into the formula

[0067]

[0068] We get: △S m = 13 mm, that is, the upper opening amount between the 200th ring and the 201st ring of segments is 8 mm.

[0069] Similarly, we get: △X m= 10 mm, △Z m = 5 mm, △Y m = 7 mm, that is, the opening at the lower part between the 200th and 201st segments is 10 mm, 5 mm on the left side, and 7 mm on the right side.

[0070] Embodiment 2: This embodiment is an automatic acquisition method for the opening of segments during the shield tunneling construction stage, which specifically includes the following steps:

[0071] S100. Obtain the diameter D, width e, and taper p of the segments within the corresponding section of the m-th segment, as well as the number q of assembly points and the assembly point i corresponding to the m-th segment.

[0072] S200. Obtain the shield machine strokes corresponding to the upper, lower, left, and right four feature points on the shield machine when advancing to the (m - 1)-th and m-th segments, as well as the cylinder strokes corresponding to each feature point.

[0073] S210. Obtain the cutter head center stroke T of the shield machine when advancing to the (m - 1)-th segment (m-1) , as well as the horizontal trend K of the shield machine (m-1)s and the vertical trend K (m-1)c .

[0074] S220. Obtain the cutter head center stroke T of the shield machine when advancing to the m-th segment m , as well as the horizontal trend K of the shield machine ms and the vertical trend K mc .

[0075] S230. Based on the cutter head center strokes T (m-1) and T m , the horizontal trends K (m-1)s and K ms , the vertical trends K (m-1)c and K mc , as well as the diameter D of the segments, determine the shield machine strokes of each feature point on the cutter head of the shield machine.

[0076] T ms = T m - D * K mc / 2

[0077] T mx = T m + D * K mc / 2

[0078] T mz = T m + D * K ms / 2

[0079] T my = T m - D * K ms / 2

[0080] Among them, T ms is the shield machine travel corresponding to the characteristic point on the upper part of the cutter head of the shield machine when advancing to the m-th segment ring, T mx is the shield machine travel corresponding to the characteristic point on the lower part of the cutter head when advancing to the m-th segment ring, T mz is the shield machine travel corresponding to the characteristic point on the left side of the cutter head when advancing to the m-th segment ring, T my is the shield machine travel corresponding to the characteristic point on the right side of the cutter head when advancing to the m-th segment ring.

[0081] S300. Calculate the segment width corresponding to each characteristic point on the m-th segment ring based on the width e and the wedge amount p, as well as the number q of segment assembly positions and the assembly position i corresponding to the m-th ring.

[0082]

[0083] Among them, g ms is the segment width corresponding to the upper characteristic point when the segment assembly position of the m-th segment ring is at point i, g mx is the segment width corresponding to the lower characteristic point when the segment assembly position of the m-th segment ring is at point i, g mz is the segment width corresponding to the left characteristic point when the segment assembly position of the m-th segment ring is at point i, g my is the segment width corresponding to the right characteristic point when the segment assembly position of the m-th segment ring is at point i.

[0084] S400. Determine the segment travel corresponding to each characteristic point at the front end of the (m - 1)-th and m-th segment rings based on the shield machine travel and the cylinder travel corresponding to each characteristic point when advancing to the (m - 1)-th and m-th segment rings.

[0085] S m = T ms - l - a m = T m - D * K mc / 2 - l - a m

[0086] X m = T mx - l - b m = T m + D * K mc / 2 - l - b m

[0087] Z m = T mz - l - c m = T m + D * K ms / 2 - l - c m

[0088] Ym = T my - l - d m = T m - D * K ms / 2 - l - d m

[0089] Wherein, S m is the segment travel corresponding to the upper front feature point of the m-th segment ring, X m is the segment travel corresponding to the lower front feature point of the m-th segment ring, Z m is the segment travel corresponding to the left front feature point of the m-th segment ring, Y m is the segment travel corresponding to the right front feature point of the m-th segment ring, W m is the shield machine travel corresponding to the upper feature point of the m-th segment ring being pushed to, l is the sum of the lengths of the cutter head, front shield, and middle shield (the distance from the cutter head to the front end face of the cylinder), a m is the cylinder travel corresponding to the upper feature point of the m-th segment ring being pushed to, b m is the cylinder travel corresponding to the lower feature point of the m-th segment ring being pushed to, c m is the cylinder travel corresponding to the left feature point of the m-th segment ring being pushed to, d m is the cylinder travel corresponding to the right feature point of the m-th segment ring being pushed to.

[0090] S500. Based on the segment travels corresponding to the respective feature points at the front ends of the (m - 1)-th and m-th segment rings, and the segment widths corresponding to the respective feature points on the m-th segment ring, determine the segment opening amounts corresponding to the respective feature points between the m-th segment ring and the (m - 1)-th segment ring.

[0091]

[0092] The following is illustrated with a specific example:

[0093] The segment width of a certain section is 1.5 m, the outer diameter of the segment is 6 m, the taper is 34 mm. After the 100th ring is pushed, the cutter head travel is 161.751 m. At this time, the horizontal trend of the shield machine is 5 mm / m, and the vertical trend is 7 mm / m. There are 12 segment assembly points in this section. The assembly point of the 100th segment ring is point 2. The upper, lower, left, and right cylinder travels are 1873 mm, 1864 mm, 1881 mm, and 1853 mm respectively.

[0094] After the 101st ring is pushed, the cutter head travel is 163.177 m. At this time, the horizontal trend of the shield machine is 2 mm / m, and the vertical trend is 12 mm / m. The segment assembly point of the 101st ring is point 5. The upper, lower, left, and right cylinder travels are 1761 mm, 1813 mm, 1773 mm, and 1783 mm respectively.

[0095] Substitute the above shield parameters into the formula

[0096]

[0097] We get: △S m = 8.3 mm, that is, the opening between the upper parts of the 100th and 101st segments is 8 mm.

[0098] Similarly, we get: △X m = 6.7 mm, △Z m = 16.5 mm, △Y m = 13.5 mm, that is, the opening between the lower parts of the 100th and 101st segments is 6.7 mm, 16.5 mm on the left side, and 13.5 mm on the right side.

[0099] Example 3: This example is basically the same as Example 2, the only difference being that this example refines and supplements the calculation of the opening when the tunnel enters the circular curve section (when the mth segment is in the circular curve section), including:

[0100] When the tunnel enters the circular curve section, the influence of the deflection amount in the turning section on the four characteristic points needs to be considered. Taking a right turn as an example, with the turning radius being R, the deflection amount (△h) when the shield tunneling is consistent with the segment width is:

[0101]

[0102] However, it is usually difficult for the shield machine to ensure that the propulsion length of each ring is consistent with the segment width. Therefore, it is necessary to convert the deflection amount, that is:

[0103]

[0104] Where △h m is the actual deflection amount after the shield has advanced the mth ring, positive for a right turn and negative for a left turn; T m-1 is the center travel of the cutterhead of the (m - 1)th ring. Then the left and right side travels of the cutterhead in the circular curve section are:

[0105]

[0106] Then the opening amounts of the left and right side segments are:

[0107]

[0108] Similarly, when the shield is in the vertical curve section, the opening amounts of the upper and lower segments are:

[0109]

[0110] Example 4: This example is basically the same as Example 2, except that in this example, the calculation of the opening amount is refined and supplemented when the tunnel enters the transition curve section (when the m-th segment is in the transition curve section), including:

[0111] The deflection amount of the segments in the transition curve section increases uniformly as the straight-transition point changes to the transition-circular point, until it is consistent with the deflection amount in the circular curve section. When the length of the transition curve section is t, when the segments are assembled to the m-th ring, and the length from the segment to the starting point of the curve section is j (0 < j < t), and the turning radius of the circular curve section is R, then the deflection amount of each ring in the circular curve section is:

[0112]

[0113] The deflection amount per meter of the circular curve is:

[0114]

[0115] Then the deflection amount per meter of the segments assembled to length j on the transition curve is:

[0116]

[0117] Then the deflection amount of each segment assembled to length j on the transition curve is:

[0118]

[0119] However, it is usually difficult for the shield machine to ensure that the propulsion length of each ring is consistent with the segment width. Therefore, it is necessary to convert the deflection amount, that is:

[0120]

[0121] Then the opening amounts of the segments at the four characteristic points in the transition curve section are:

[0122]

[0123] Example 5: This example is an automatic acquisition device for the opening amount of segments during the shield construction stage, specifically including:

[0124] A segment information acquisition module, used to acquire the width e and wedge amount p of the segments in the corresponding interval of the m-th segment, as well as the number q of assembly points and the assembly point i corresponding to the m-th ring;

[0125] A propulsion information acquisition module, always used to acquire the shield machine travel corresponding to multiple characteristic points on the shield machine when propelling to the (m - 1)-th and m-th segments, as well as the cylinder travel corresponding to each characteristic point, where the multiple characteristic points include upper, lower, left, and right characteristic points;

[0126] The segment width calculation module is used to calculate the segment widths corresponding to the characteristic points on the m-th ring segment based on the width e, the wedge amount p, the number q of assembly points, and the assembly point i corresponding to the m-th ring.

[0127] The segment travel calculation module is used to determine the segment travels corresponding to the front-end characteristic points of the (m - 1)-th and m-th ring segments based on the shield machine travels and the cylinder travels corresponding to the characteristic points when the shield machine advances to the (m - 1)-th and m-th ring segments.

[0128] The opening amount calculation module is used to determine the segment opening amounts corresponding to the characteristic points between the m-th ring segment and the (m - 1)-th ring segment based on the segment travels corresponding to the front-end characteristic points of the (m - 1)-th and m-th ring segments and the segment widths corresponding to the characteristic points on the m-th ring segment.
