SUMMARY

[0004] The utility model solves the technical problems that the prior art lacks, and provides an improved plugging device for a shield segment hoisting hole or a reserved grouting hole.

[0005] To solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A plugging device for a shield segment hoisting hole or a reserved grouting hole includes a material cylinder containing sealing material, a pre-embedded part arranged in a hole to be plugged in the segment, and a base, an adjusting component, and a material pressing component detachably connected to the pre-embedded part. The base has a through channel communicating with the hole and matching the material cylinder. The material cylinder passes through the through channel and extends into the hole. The adjusting component adjusts the base and drives the center line of the through channel to be parallel or coincident with the center line of the hole. The material pressing component includes a material pressing module inserted into the material cylinder and an operating member mounted on the base and capable of driving the material pressing module to move axially along the material cylinder to drive the sealing material to be pressed into the hole.

[0007] According to one specific implementation and preferred aspect of the utility model, the end of the material cylinder extending into the hole is provided with a sealing plate, and a filling area of the sealing material is formed between the sealing plate and the inner wall of the hole. Here, the filling area formed between the sealing plate and the inner wall of the hole ensures that the filled sealing material is concentrated in a fixed area, improving the packing density.

[0008] Preferably, the outer diameter of the sealing plate is smaller than the inner diameter of the through channel. Here, the gas in the hoisting hole (reserved grouting hole) can be smoothly discharged, and the packing density is ensured.

[0009] According to another specific implementation and preferred aspect of the utility model, the adjusting part includes a plurality of adjusting columns distributed on the base in a circumferential interval around the penetrating channel, wherein each adjusting column abuts on the wall surface of the segment from one end and adjusts the spacing between the corresponding part on the base and the wall surface of the segment.

[0010] According to another specific implementation and preferred aspect of the utility model, the base includes a seat body, a connecting sleeve with the penetrating channel formed therein, wherein the connecting sleeve is fixedly connected with the embedded part, and the seat body is sleeved on the connecting sleeve.

[0011] Preferably, the connecting sleeve includes a first pipe body and a second pipe body, wherein one end of the first pipe body is threadedly connected with the embedded part, the other end penetrates through the seat body and is threadedly connected with the second pipe body. Here, based on the connection of the first pipe body with the embedded part, the spacing between the seat body and the wall surface of the segment is adjusted by the plurality of adjusting columns, and finally the second pipe body is connected with the end of the first pipe body to press the seat body towards the segment to achieve fixation.

[0012] According to another specific implementation and preferred aspect of the utility model, the operating part includes a support rod fixedly connected on the base, a connecting rod rotatably connected on the support rod through a first bearing, and an action rod rotatably connected between the connecting rod and the material pressing module through a second bearing and a third bearing respectively, wherein the action rod synchronously drives the material pressing module to reciprocate along the material cylinder in an axial direction as the connecting rod swings around the first bearing.

Here, the filling direction is more accurate, and the friction between the material pressing module, the material cylinder and the penetrating channel is reduced, prolonging the service life.

[0015] Preferably, the center lines of the push rod, the material pressing module and the material cylinder coincide.

[0016] Thanks to the implementation of the above technical solutions, the utility model has the following advantages compared with the prior art:

[0017] Existing technologies only allow filling sealing material into the hoisting hole or pre-reserved grouting hole using a material cylinder. Due to the curved surface of the tunnel segment wall, installing the material cylinder is difficult, and the filling direction cannot be precisely controlled, resulting in poor sealing performance as the sealing material cannot penetrate deeply to the bottom of the hole. This application, however, provides a comprehensive design for the sealing device of the shield tunnel segment hoisting hole or pre-reserved grouting hole, cleverly overcoming the shortcomings and defects of existing technologies. With this sealing device, the material cylinder containing the sealing material is passed through the insertion channel on the base and inserted into the hole. Then, the base is adjusted by adjusting components so that the center line of the insertion channel is parallel or coincident with the center line of the hole to be sealed, and the base is fixedly connected to the embedded parts in the hole to be sealed. Finally, the pressing module is inserted into the material cylinder, and the pressing module is driven by the operating components to move axially along the material cylinder to force the sealing material into the hole, completing the sealing. Therefore, compared with the prior art, this utility model has two advantages. First, it is based on the adjustment of the base to keep the insertion channel parallel or coincident with the center line of the hole, so that the material cylinder can pass through the insertion channel and penetrate into the hole to accurately fill the material and effectively improve the sealing effect. Second, it is simple and convenient to install and can be reused. Attached Figure Description

[0033] Embodiment 1

[0034] As shown in Figure 1 and Figure 2 The present embodiment relates to a shield segment hoisting hole or a reserved grouting hole sealing device, which comprises a material cylinder 1 with sealing material built-in, a base 2, an adjusting component 3 and a pressing component 4. A pre-embedded part J is arranged in the hole of the shield segment P hoisting hole or the reserved grouting hole.

[0035] Specifically, the base 2 is detachably connected with the pre-embedded part J, wherein a through channel t is formed on the base 2 and communicates with the hole and matches the material cylinder 1, and the material cylinder 1 passes through the through channel t and extends into the hole.

[0036] In order to facilitate implementation, an end portion of the material cylinder 1 extending into the hole is provided with a sealing plate 10, and a filling area of the sealing material is formed between the sealing plate 10 and the inner wall of the hole. Here, the filling area formed between the sealing plate and the inner wall of the hole is used to ensure that the filled sealing material is concentrated in the fixed area and improve the filling density. At the same time, the outer diameter of the sealing plate 10 is smaller than the inner diameter of the through channel t. Here, it can be ensured that the gas in the hoisting hole (reserved grouting hole) is smoothly discharged, and the filling density is ensured. Further, the material cylinder 1 is spaced apart from the inner wall of the through channel t, so as to facilitate the adjustment of the depth of the hole.

[0037] In this example, the base 2 comprises a seat body 20 with a rectangular cross section, and a connecting sleeve 21 with the through channel t, wherein the connecting sleeve 21 is fixedly connected with the pre-embedded part J, and the seat body 20 is sleeved on the connecting sleeve 21.

[0038] Specifically, the connecting sleeve 21 comprises a first pipe body 211 and a second pipe body 212, wherein the first pipe body 211 is inserted into the embedded part J at one end and is threadedly connected with the inner wall of the embedded part J at the outer periphery, and the other end is threaded out of the seat body 20 and is threadedly connected with the second pipe body 212.

[0039] In this example, the adjusting component 3 is used to adjust the base 2 and drive the center line of the insertion channel t to be parallel or coincident with the center line of the hole.

[0040] In some embodiments, the adjusting component 3 comprises a plurality of adjusting columns 30 distributed on the base 2 in a circumferential direction around the insertion channel t, wherein each adjusting column 30 abuts against the wall of the pipe piece at one end and adjusts the spacing between the corresponding part of the base 2 and the wall of the pipe piece. Each adjusting column 30 is provided with a bolt for facilitating the adjusting operation. Here, after the first pipe body is connected with the embedded part, the spacing between the seat body and the wall of the pipe piece is adjusted by the plurality of adjusting columns, and finally the first pipe body is connected with the end of the second pipe body to press the seat body towards the pipe piece to achieve fixation.

[0041] In this example, the pressing component 4 comprises a pressing module 40 capable of being inserted into the material cylinder 1, an operating member 41 mounted on the base 2 and capable of driving the pressing module 40 to move axially along the material cylinder 1 to drive the sealing material to be pressed into the hole.

[0042] In some embodiments, the operating member 41 comprises a support rod 410 fixedly connected to the base 2, a connecting rod 411 rotatably connected to the support rod 410 through a first bearing c1, and an acting rod 412 rotatably connected between the connecting rod 411 and the pressing module 40 through a second bearing c2 and a third bearing c3, respectively. When the connecting rod 411 swings around the first bearing c1, the acting rod 412 synchronously drives the pressing module 40 to move axially along the material cylinder 1 reciprocally.

[0043] In addition, the length of the part of the connecting rod 411 between the first bearing c1 and the second bearing c2 is 0.15-0.3 times the total length of the connecting rod 411, and in this embodiment, the preferred value is 0.2 times. Here, the operation is labor-saving.

[0044] In summary, after the plugging device is taken, the material cylinder with the plugging material is inserted through the insertion channel on the base and extends into the hole; then the base is adjusted by the adjusting component to make the center line of the insertion channel parallel to or coincide with the center line of the hole to be plugged, and the base is fixedly connected with the embedded part in the hole to be plugged; finally, the pressing module is inserted into the material cylinder, and the pressing module is driven to move axially along the material cylinder by the operating component to drive the plugging material to be pressed and filled into the hole, and the plugging is completed. Therefore, compared with the prior art, on the one hand, the adjustment based on the base is used to keep the insertion channel parallel to or coincide with the center line of the hole, so that the material cylinder can be inserted through the insertion channel and deep into the hole, and the filling material can be accurately implemented, and the plugging effect is effectively improved; on the other hand, the installation is simple and convenient, and the repeated use can be realized; on the third hand, the gas in the lifting hole (the reserved grouting hole) can be smoothly discharged, and the filling density is ensured, and further, the material cylinder is separated from the inner wall of the insertion channel, so that the depth of extending into the hole can be adjusted; on the fourth hand, the operation is convenient and labor-saving.

Here, the filling direction is more accurate, and the friction between the pressing module, the material cylinder and the insertion channel is reduced, and the service life is prolonged.

[0048] In some specific embodiments, the center lines of the push rod 414, the pressing module 40 and the material cylinder 1 coincide.
