The construction of underground stations, sections, and passageways in urban rail transit primarily involves various methods, including open-cut, mining, shield, and pipe jacking. Waterproofing measures include full-cover flexible waterproofing, partial-cover flexible waterproofing, and self-waterproofing. The use of waterproofing membranes is primarily concentrated in open-cut and mining structures.

[0003] However, the existing pre-laid waterproof membranes have poor bonding strength, adhesion and impermeability at the lap joints, so we propose a mechanical connection structure for pre-laid waterproof membranes to solve the above problems. Utility Model Content

[0024] When it is necessary to use pre-laid waterproof membrane, the user can first lay the second polymer carcass 2 at the designated position, and then lay two identical first polymer carcasses 1 in a symmetrical manner on both sides of the top surface of the second polymer carcass 2, and through the sealing receiving port strip 5 on the second polymer carcass 2, it can be snap-fitted and connected with the sealing pressing port strip 6 on the first polymer carcass 1, so that the second polymer carcass 2 and the two first polymer carcasses 1 can be connected into a whole, and through the second adhesive layer 7 on the second polymer carcass 2, the connection strength and sealing of the overlap between the second polymer carcass 2 and the first polymer carcass 1 can be strengthened, and a high waterproof effect can be achieved. The user can also use two first polymer carcasses The bodies 1 are laid out in sequence, and the sealing pressing port strip 6 on one of the first polymer carcasses 1 is engaged with the sealing receiving port strip 5 on the first polymer carcass 1 located below, so that the two first polymer carcasses 1 can be overlapped and connected, and laid out in sequence, so that multiple first polymer carcasses 1 can be connected, and the second adhesive layer 7 on the first polymer carcass 1 located above can also bond the bottom side of the first polymer carcass 1 located below, so as to improve the connection strength and sealing at the overlap of the two adjacent first polymer carcasses 1. The first polymer carcass 1 can be protected by the pressure-sensitive adhesive layer 3 and the PE protective layer 4, thereby improving the service life of the first polymer carcass 1.

[0025] See Figures 1-4 The sealing receiving port strip 5 includes a U-shaped strip 51.

Since an inclined surface is provided on the inner side of the top of the claw 52, ​​the sealing press-in port strip 6 can be smoothly inserted into the U-shaped strip 51. At the same time, the inserted sealing press-in port strip 6 can be bonded through the first adhesive layer 53, thereby improving the stability of the sealing press-in port strip 6 after insertion. The first release film layer 54 can protect the first adhesive layer 53 and can be easily torn off when it is needed.

[0027] See Figure 1 、 Figure 5The sealing press-in port strip 6 includes a vertical strip 61, and a card strip 62 is integrally formed at the bottom end of the vertical strip 61. The main view of the card strip 62 is a square with missing edges;

[0030] During operation, when it is necessary to use the pre-laid waterproof membrane, the user can first lay the second polymer carcass 2 at the designated position, and then lay two identical first polymer carcasses 1 in a symmetrical manner on both sides of the top surface of the second polymer carcass 2, and through the sealing receiving port strip 5 on the second polymer carcass 2, it can be snap-fitted and connected with the sealing pressing port strip 6 on the first polymer carcass 1, so that the second polymer carcass 2 and the two first polymer carcasses 1 can be connected into a whole, and through the second adhesive layer 7 on the second polymer carcass 2, the connection strength and sealing of the overlap between the second polymer carcass 2 and the first polymer carcass 1 can be strengthened, and a high waterproof effect can be achieved. The user can also use two first polymer carcasses The sub-carcasses 1 are laid out in sequence, and the sealing pressing port strip 6 on one of the first polymer carcasses 1 is engaged in the sealing receiving port strip 5 on the first polymer carcass 1 located below, so that the two first polymer carcasses 1 can be overlapped and connected, and laid out in sequence, so that multiple first polymer carcasses 1 can be connected, and the second adhesive layer 7 on the first polymer carcass 1 located above can also bond the bottom side of the first polymer carcass 1 located below, so as to improve the connection strength and sealing at the overlap of the two adjacent first polymer carcasses 1. The first polymer carcass 1 can be protected by the pressure-sensitive adhesive layer 3 and the PE protective layer 4, thereby improving the service life of the first polymer carcass 1.

[0031] The U-shaped strip 51 in the sealing receiving port strip 5 can be attached to the pressure-sensitive adhesive layer 3 of the first polymer matrix 1 and the second polymer matrix 2, and can cooperate with the two claws 52 to clamp and limit the inserted sealing press-in port strip 6, so that the two can be connected together. Since an inclined surface is provided on the inner side of the top of the claw 52, ​​the sealing press-in port strip 6 can be smoothly inserted into the U-shaped strip 51. At the same time, the inserted sealing press-in port strip 6 can be bonded through the first adhesive layer 53, thereby improving the stability of the sealing press-in port strip 6 after insertion. The first release film layer 54 can protect the first adhesive layer 53 and can be easily torn off when it is needed.

[0032] The vertical strip 61 in the sealed press-fit port strip 6 can be attached to the bottom surface of the first polymer matrix 1, and can also be inserted into the U-shaped strip 51 through the card strip 62 whose main appearance is a square with missing edges. Under the action of the two claws 52, the card strip 62 can be locked and limited, thereby preventing the vertical strip 61 from falling off from the U-shaped strip 51, ensuring the stability of the engagement between the two. Since the second adhesive layer 7 is provided with a second release film layer 8 on the upper surface, the second adhesive layer 7 can be effectively protected, thereby ensuring that the bonding strength of the second adhesive layer 7 is maintained after the second release film layer 8 is torn off.
