Description

Technical Field

[0001] The present invention relates to the technical field of communication channel construction, and more specifically to a large fault-tolerant anti-spurting 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 crossing complex strata and water-rich soft soil strata. 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, and excavation and construction are carried out under the protection of the frozen wall. During the freezing process, freezing pipes are drilled into the strata, and salt water circulates inside the freezing pipes to freeze the strata. During the construction process, it is usually necessary to drill through holes to transmit salt water, cables, etc. from one tunnel to the other tunnel. The through holes also circulate salt water and are used 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 at this time, the through-hole sealing device will fail, causing water-conducting cracks between the stratum and the segment, 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 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 enclose a circumferentially closed anti-surge receiving space. One end of the anti-surge receiving space is sealed and fitted 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 determined. 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 accurately judge. 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 upright plate 101, a first fixed flange 104 and a first connecting flange 105. The first corner connecting upright plate 101 is bent along its middle position, and the bending line of the first corner connecting upright plate 101 is arranged along the through hole drilling direction. The first fixed flange 104 is fixedly connected to the first end of the first corner connecting upright 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, and the first connecting flange 105 is fixedly connected to both sides of the first corner connecting upright plate 101. The side edges of the first corner connecting upright plate 101 are fixedly connected to the side edges 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 the two 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 inner retracted plate 102 is fixedly connected to the second end of the first corner connecting vertical plate 101, and the second inner retracted plate 202 is fixedly connected to the second end of the first extended vertical plate 201. The first inner retracted plate 102 and the second inner retracted plate 202 both extend toward the center of the anti-spurting receiving space. The first connecting protrusions 105 are also fixedly connected to both sides of the first inner retracted plate 102, and the second connecting protrusions 205 are also fixedly connected to both sides of the second inner retracted plate 202. The side edges of the first inner retracted plate 102 and the side edges of the second inner retracted plate 202 are sealed and fixedly connected. By providing the first inner retracted plate 102 and the second inner retracted plate 202, the opening size of the open end of the anti-spurting receiving space is reduced, and when water gushing occurs, it is convenient to quickly carry out plugging construction.

[0036] like Figure 4 As shown, the first inner retracted plate 102 is fixedly connected to the end portion extending toward the center of the anti-spurting receiving space with the second corner connecting vertical plate 103, and the second inner retracted plate 202 is fixedly connected to the end portion extending toward the center of the anti-spurting receiving space with the second extended vertical plate 203. The second corner connecting vertical plate 103 and the second extended vertical plate 203 are both arranged along the through-hole drilling direction; the second corner connecting vertical plate 103 is also fixedly connected to the two sides with the first connecting flange 105, and the second extended vertical plate 203 is also fixedly connected to the two sides with the second connecting flange 205, and the side edges of the second corner connecting vertical plate 103 and the side edges of the second extended vertical plate 203 are connected to each other. 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, the steel plate is directly welded to the surrounding of the anti-gushing receiving space to quickly seal it. Then the grouting equipment is used to inject grout into the gushing position to achieve the effect of blocking water.

Point A2 is the calculated position of the through hole, and the connection line between points A1 and A2 is parallel to the connection line between points O1 and O2; use the total station to find the point A1′ with the same coordinates as the hole position of point A1 on the fixed structure behind point A1, which is the backsight point of A1.

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

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