Description

Technical Field

[0001] The present invention relates to the technical field of communication channel construction, in particular to a large fault-tolerant anti-surge receiving device and a method for identifying the position of a communication channel through-hole. Background Art

[0002] The freezing method is an important construction method for traversing complex strata and water-rich soft soil. It uses artificial refrigeration to freeze the water in the soil into ice, forming a solid, closed frozen soil ring (frozen wall) to resist water and soil pressure and isolate groundwater. Excavation and construction can then be carried out under the protection of the frozen wall. During the freezing process, freezing pipes are drilled into the stratum, and salt water circulates inside the freezing pipes to freeze the stratum. During the construction process, it is usually necessary to drill through holes to transfer salt water, cables, etc. from one tunnel to the other. These holes also circulate salt water and serve as freezing pipes.

[0003] During the through-hole construction using the artificial freezing method, the drill bit penetrates the tunnel segment on the non-excavation side. If the drill bit penetrates the bolt hole of the tunnel segment or the seam between the tunnel segments, the through-hole sealing device will fail, causing water-conducting cracks between the stratum and the segments, which will cause water and sand gushing accidents under the action of high water pressure.

DETAILED DESCRIPTION

[0030] Example 1

[0031] The large fault-tolerant anti-surge receiving device in this embodiment is as follows: Figure 1-2 As shown, it includes a standard corner module 1 and an extended connection module 2. The standard corner modules 1 are arranged on all four sides of the position where the through holes on the tunnel segment pass through. The standard corner modules 1 are arranged on the tunnel segment along the drilling direction of the through holes on the tunnel segment. The first end of the standard corner module 1 is sealed and fixedly connected to the surface of the tunnel segment. At least one extended connection module 2 is arranged between two adjacent standard corner modules 1. The first end of the extended connection module 2 is sealed and fixedly connected to the surface of the tunnel segment. The two side walls of the extended connection module 2 are respectively sealed and fixedly connected to the standard corner modules 1 on both sides. The standard corner module 1 and the extended connection module 2 are sequentially connected to each other to form a circumferentially closed anti-surge receiving space. One end of the anti-surge receiving space is sealed in contact with the tunnel segment, and the other end of the anti-surge receiving space is open.

[0032] During the actual drilling construction process, the drilling position of the drill bit can be accurately measured. When the drill bit is drilling in the formation, it is disturbed by various environmental factors, causing the drill bit's drilling position to deviate to a certain extent, and the deviated position is often impossible to judge completely and accurately. The large-tolerance anti-surge receiving device in this embodiment adopts an anti-surge receiving space within a larger range. Even if the drill bit's drilling position deviates to a certain extent, it can still enter the anti-surge receiving space to play a protective role.

[0033] like Figure 3 As shown, the standard corner module 1 includes a first corner connecting vertical plate 101, a first fixed flange 104 and a first connecting flange 105. The first corner connecting vertical plate 101 is bent along its middle position, and the bending line of the first corner connecting vertical plate 101 is set along the through-hole drilling direction. The first fixed flange 104 is fixedly connected to the first end of the first corner connecting vertical plate 101, and the first fixed flange 104 extends to the outside of the anti-surge receiving space. The first fixed flange 104 is fixedly connected to the tunnel segment by bolts. The first connecting flange 105 is fixedly connected to both sides of the first corner connecting vertical plate 101, and the side of the first corner connecting vertical plate 101 is fixedly connected to the side of the extended connection module 2 through the first connecting flange 105.

[0034] like Figure 4As shown, the extended connection module 2 includes a first extended vertical plate 201, a second fixed flange 204 is fixedly connected to the first end of the first extended vertical plate 201 in a direction away from the anti-surge receiving space, and second connecting flanges 205 are fixedly connected to both sides of the first extended vertical plate 201 in a direction away from the anti-surge receiving space, the second fixed flange 204 is fixedly connected to the tunnel segment by bolts, the second connecting flange 205 is fixedly connected to the first connecting flange 105 by bolts, and a sealing strip is installed between the second connecting flange 205 and the first connecting flange 105.

[0035] like Figure 3 As shown, the first inward-retracting plate 102 is fixedly connected to the second end of the first corner connecting upright 101, and the second inward-retracting plate 202 is fixedly connected to the second end of the first extended upright 201. The first inward-retracting plate 102 and the second inward-retracting plate 202 both extend toward the center of the anti-surge receiving space. The first connecting flanges 105 are also fixedly connected to both sides of the first inward-retracting plate 102, and the second connecting flanges 205 are also fixedly connected to both sides of the second inward-retracting plate 202. The side edges of the first inward-retracting plate 102 and the side edges of the second inward-retracting plate 202 are sealed and fixedly connected. The provision of the first inward-retracting plate 102 and the second inward-retracting plate 202 reduces the size of the open end of the anti-surge receiving space, facilitating rapid sealing in the event of water inrush.

[0036] like Figure 4 As shown, the second corner connecting vertical plate 103 is fixedly connected to the end of the first inward-facing plate 102 extending toward the center of the anti-surge receiving space, and the second extended vertical plate 203 is fixedly connected to the end of the second inward-facing plate 202 extending toward the center of the anti-surge receiving space. The second corner connecting vertical plate 103 and the second extended vertical plate 203 are both arranged along the through-hole drilling direction. The first connecting flange 105 is also fixedly connected to both sides of the second corner connecting vertical plate 103, and the second extended vertical plate 203 is also fixedly connected to both sides of the second extended vertical plate 203. The side edges of the second corner connecting vertical plate 103 and the side edges of the second extended vertical plate 203 are interconnected. By providing the second corner connecting vertical plate 103 and the second extended vertical plate 203, the receiving space can be further increased. In actual application, quick cement is filled in the anti-gushing receiving space. When water gushes out, the steel plate is directly welded to the periphery of the anti-gushing receiving space to quickly seal it. Grouting equipment is then used to inject grout into the gushing position to achieve the effect of blocking water.

[0037] Example 2

[0038] The method for identifying the position of a communication channel through-hole in this embodiment includes the following steps:

[0039] Step A: Using a total station to observe known points P1 and P2 in the excavated tunnel, determine the three-dimensional coordinate point P0 of the total station in the excavated tunnel space, convert the three-dimensional coordinate point P0 into the communication channel coordinates, and establish the total station;

[0041] Step C: Based on the connecting line of O1 and O2, start the total station laser irradiation, illuminate the excavated side tunnel to obtain point A1, and obtain the coordinates of the laser point A1. Point A1 is the through hole drilling position in the excavated side tunnel, and point A1 is marked on the tunnel segment. In the same way, use the total station in the trenchless side tunnel to obtain the through hole drilling position A2, and mark point A2 on the tunnel segment. Point A2 is the calculated position of the through hole. The connecting line of points A1 and A2 is parallel to the connecting line of points O1 and O2. Use the total station to find a point A1′ on the fixed structure behind point A1 with the same coordinates as the hole position of point A1, which is the backsight point of A1. The connecting line of A1′ and A1 is parallel to the connecting line of points O1 and O2, and auxiliary verification is performed through A1′.

[0042] Step D: Conduct through-hole drilling from point A1 to point A2 in the excavated tunnel;

[0043] Step E: After the drill bit rubs against the trenchless tunnel segment, an acoustic imager is placed in the exit area to accurately determine the through-hole exit location;

[0044] Step F: Installing the large fault-tolerant anti-surge receiving device described in Example 1 at the through-hole exit position on the tunnel segment to provide protection, and filling the anti-surge receiving space of the large fault-tolerant anti-surge receiving device with quick cement;

[0045] Step G: Continue drilling until the drill bit penetrates the trenchless side tunnel pipe, completing the through-hole construction.

[0046] In step C, .

[0047] In step C, a total station is used to find a point A1′ on the fixed structure behind point A1 with the same coordinates as the hole position of point A1. This point is the backsight point of A1. The line connecting A1′ and A1 is parallel to the line connecting points O1 and O2.
