Description

Technical Field

[0001] This utility model relates to the field of underground engineering leakage point sealing technology, specifically a sealing structure for leakage point holes in underground engineering. Background Technology

[0002] Underground engineering refers to underground civil engineering projects built deep below the ground to develop and utilize underground space resources. Generally, it includes underground houses and underground structures, underground railways, highway tunnels, underwater tunnels, underground utility tunnels, and pedestrian underpasses. Due to the importance of underground engineering construction, various retaining structures are used during the construction process for safety reasons.

[0003] Due to the use of the enclosure structure, leakage points or leakage lines often occur during normal use. In order to deal with these leakage points and holes, it is necessary to seal them. This requires the use of a sealing structure to complete the work. However, if grouting is used for sealing, it will easily affect the convenience of on-site operation and affect the progress of the sealing process. Utility Model Content

[0004] The purpose of this utility model is to provide a sealing structure for seepage points and holes in underground engineering, so as to solve the problem mentioned in the background art that in order to deal with these seepage points and holes, it is necessary to seal them, which requires the use of a sealing structure to complete the work. However, if grouting is used for sealing, it will easily affect the convenience of on-site operation and the progress of the sealing process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sealing structure for seepage points in underground engineering, comprising a sealing plate and a base plate. The sealing plate has a second guide hole at both its top and bottom ends, and a first guide hole at each of its top and bottom ends near the second guide holes. An adjustment groove is formed between the first and second guide holes. Guide rails are fixed to the top and bottom ends of the inner wall of the adjustment groove. Guide blocks are connected to the outer walls of the guide rails. A buffer column is fixed between the guide blocks. A pad is fixed to one side of the buffer column. A second positioning groove is formed inside the pad. A first positioning groove is located at the top of the second positioning groove. A buffer spring is connected to the outer wall of one side of the buffer column.

[0006] Preferably, the second guide holes are symmetrically distributed about the horizontal central axis of the sealing plate, and the first guide holes are symmetrically distributed about the horizontal central axis of the sealing plate.

[0007] Preferably, the second positioning groove and the first positioning groove are symmetrically distributed about the horizontal central axis of the pad, and the adjusting groove is symmetrically distributed about the horizontal central axis of the sealing plate.

[0008] Preferably, the guide rails are symmetrically distributed about the horizontal central axis of the adjusting groove, a sliding connection is formed between the guide rails and the guide block, and one side of the buffer spring is elastically connected to one side of the sealing plate.

[0009] Preferably, a sealing block is fixed at the middle position on one side of the sealing plate, and a sealing groove is formed inside the sealing block. A first guide post is installed on one side of the base plate near the top and bottom ends, and a second guide post is installed on one side of the base plate near the first guide post. An installation bolt is installed on the other side of the base plate.

[0010] Preferably, the first guide posts are symmetrically distributed about the central axis of the base plate, the second guide posts are symmetrically distributed about the central axis of the base plate, and the mounting bolts are symmetrically distributed about the central axis of the base plate.

[0011] Preferably, a reserved groove is provided in the middle of the interior of the base plate, an elastic block is fixed to the inner wall of the reserved groove, and a sealing ring is fixed to one end of the elastic block.

[0012] Preferably, both the sealing plate and the base plate have a shaping plate fixed inside. One end of the shaping plate is fixed with a positioning seat, and both sides of the positioning seat are fixed with fixing blocks. The positioning seat has an installation groove inside, and a support ball is fixed inside the installation groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the sealing structure for seepage points in underground engineering not only improves the sealing effect, but also improves the sealing capacity and strength of the sealing structure.

[0014] (1) The base plate is fixed by using the mounting bolts, so that the position of the permeation hole is located in the reserved groove. This ensures the stability of the base plate and the contact surface after installation. Then, the sealing plate is used, so that the second guide hole of the sealing plate is inserted into the first guide post, and the first guide hole is inserted into the second guide post. The sealing block is made to pass through the reserved groove, so that the permeation hole is sealed by the sealing block. During the insertion process, the base plate will contact the pad first. Therefore, the first guide post will pass through the first positioning groove first, and the second guide post will pass through the second positioning groove first. At the same time, the buffer spring contracts and the buffer post moves inside the adjustment groove. Therefore, when the sealing plate is connected to the base plate, the pad is used for cushioning protection, which also plays a buffering role during installation and improves operability. After the corresponding insertion is completed, the sealing plate and the base plate are fixed by screws, which improves convenience.

[0015] (2) By positioning the permeation hole at the location of the pre-reserved groove, and then allowing the sealing block to pass through the pre-reserved groove, the permeation hole is sealed by the sealing block. When sealing, the inner wall of the pre-reserved groove is fixed with a sealing ring and an elastic block, thus providing a certain elastic sealing effect, thereby improving the overall sealing ability during operation.

[0016] (3) By installing and fixing the shaping plate inside the sealing plate, the shaping plate is used for initial support. Then, the positioning seats are evenly distributed between the shaping plates inside the base plate. Subsequently, the position of the positioning seats is fixed by the fixing block. Then, the support ball is connected and installed between the positioning seats, which improves the overall strength of the work. Attached Figure Description

The sealing block 2 is ensured to pass through the reserved groove 10, thereby sealing the permeation hole. During the installation process, the base plate 7 will first contact the pad 11. Therefore, the first guide post 6 will first pass through the first positioning groove 12, and the second guide post 9 will first pass through the second positioning groove 13. At the same time, the buffer spring 14 contracts, and the buffer post 15 moves inside the adjustment groove 18.
