[0039] The application will be further described in detail below with reference to the accompanying drawings.

[0040] The embodiment provides a quick disassembly and quick assembly type waterproof system for underground structure deformation joint, which can form multiple waterproof lines at the deformation joint position of the underground engineering, has good waterproof effect, is easy to install and replace, and is suitable for deformation joint waterproof of various underground structures.

[0041] As shown in the drawings, Figure 1 The quick disassembly and quick assembly type waterproof system for underground structure includes a fixed clamping plate group, a fixed clamping plate anchoring rib 2, a water-swelling sealing strip A 3, a connecting plate 4, a cover connecting plate 5, a cover plate 6, a water-swelling sealing strip B 7 and a compression bolt 8. The fixed clamping plate group includes two fixed clamping plates 1 which are structurally identical.

[0042] The fixed clamping plate 1, the connecting plate 4, the cover connecting plate 5 and the cover plate 6 are all made of corrosion-resistant metal materials, and in this example, the fixed clamping plate 1, the connecting plate 4, the cover connecting plate 5 and the cover plate 6 are all made of aluminum alloy materials.

[0043] In this example, the water-swelling sealing strip A 3 is a water-swelling rubber sealing strip with a water-drop-shaped cross section, as shown in the drawings. Figure 3 The water-swelling sealing strip B 7 is a pasting type water-swelling rubber sealing strip, which is directly pasted on the fixed clamping plate 1 when used.

[0044] As shown in the drawings,

[0045] Figure 2 ​As shown, the fixed clamping plate 1 is a double-layer structure, the inner layer is a flat plate structure, and the outer layer is a rectangular tooth structure parallel to the inner layer (i.e. rectangular grooves are uniformly spaced along the length direction of the upper layer structure of the fixed clamping plate 1, thereby forming a uniformly spaced rectangular tooth structure). In use, the rectangular tooth structures of the two fixed clamping plates 1 are opposite to each other and are respectively arranged on both sides of the deformation joint of the underground structure (the distance between the two fixed clamping plates 1 is the width of the deformation joint), thereby forming a fixed clamping plate group. During pouring of the underground structure, the two fixed clamping plates 1 are poured together with the fixed plate anchoring rib 2 and the steel reinforcement cage of the underground structure to form the installation base of the waterproof system.

[0046] A water-swelling sealing strip B7 is pasted in the gap between the inner and outer layers of each fixed clamping plate 1, and the size of the water-swelling sealing strip B7 is consistent with the size of the surface of the lower flat plate structure of the fixed clamping plate 1 (i.e. completely covers the surface of the inner flat plate structure of the fixed clamping plate 1).

[0047] As shown in Figure 3 The water-swelling sealing strip A3, the connecting plate 4 and the cover plate 6 together form a waterproof unit, and in actual use, the three are a prefabricated integrated structure. The middle part of the cover plate 6 has a protrusion as a water receiving box; the middle part of the protrusion is connected with the small end of the water-swelling sealing strip A3 through the connecting plate 4. The transverse ends of the cover plate 6 are respectively provided with rectangular teeth matching the upper layer rectangular tooth structure of the fixed clamping plate 1. During installation, the rectangular tooth parts at the transverse ends of the cover plate 6 are clamped between the upper layer rectangular tooth structure of the fixed clamping plate 1 and the water-swelling sealing strip B7, so that the middle protrusion of the cover plate 6 corresponds to the position of the deformation joint, and the serrations at the ends of the cover plate 6 correspond to the upper layer rectangular tooth structure of the fixed clamping plate 1 at the corresponding position (i.e. tooth-tooth and groove-to-groove). The connecting plate 4 and the water-swelling sealing strip A3 are located inside the deformation joint, and the connecting plate 4 can make the water-swelling sealing strip A3 located at a specified position in the thickness direction of the deformation joint, so that when the water-swelling sealing strip A3 ages and causes the deformation joint to seep water, the seeped water can slowly enter the water receiving box of the cover plate 6 along the connecting plate 4.

[0048] In order to further ensure the reliable positioning of the waterproof unit and withstand a large enough water pressure, a compression bolt 8 is installed at each rectangular serration of the fixed clamping plate 1, which compresses the fixed clamping plate 1 and the cover plate 6 through the compression bolt 8; thereby the fixed clamping plate 1 and the cover plate 6 can further compress the water-swelling sealing strip B7.

[0049] A plurality of waterproof units are sequentially installed on the fixed clamping plate group along the length direction of the deformation joint to form a continuous waterproof line.

[0050] The waterproof system can form multiple waterproof lines, and can effectively ensure the waterproof performance of the deformation joint; when the groundwater reaches the water-swelling sealing strip A3 through the deformation joint, the water-swelling sealing strip A3 swells and adheres to the two side walls to prevent the groundwater from entering the water-swelling sealing strip A3, thereby forming a first waterproof line; when the water-swelling sealing strip A3 ages, the groundwater reaches the water-swelling sealing strip B7 and the cover plate 6 to form a sealing position, thereby forming a second waterproof line.

[0051] Meanwhile, the waterproof unit and the water-swelling sealing strip B7 in the system are real-time replaceable, and can be quickly disassembled and installed and replaced at any time according to the aging or damage of the component, so that the construction speed is fast, and the waterproof performance of the deformation joint part can be effectively ensured during the entire normal use period.

[0052] The quick-disassembly and quick-assembly type underground structure waterproof system is beneficial to the popularization and application of the internal waterproof system in underground engineering, and plays a promoting role in solving the waterproof effect of industrialization and industrialization of underground engineering.

[0053] Example 2

[0054] When the waterproof unit is installed in the underground limited space, the rectangular teeth on the two sides of the cover plate connecting plate 5 are staggered with the rectangular teeth on the corresponding side of the fixed clamping plate 1, then the cover plate connecting plate 5 is pushed into the gap between the outer layer of the fixed clamping plate 1 and the water-swelling sealing strip B7 along the direction perpendicular to the fixed clamping plate 1, and then the cover plate connecting plate 5 is pushed upward or downward, so that the rectangular teeth on the two sides correspond to the rectangular teeth on the fixed clamping plate 1; and in this way, only the length of a rectangular tooth needs to be pushed along the length direction in the gap to realize the installation of the cover plate connecting plate 5, so that the installation method is simple (the water-swelling sealing strip B7 is made of rubber material and is relatively soft, if the cover plate connecting plate 5 is pushed from top to bottom, the water-swelling sealing strip B7 will be deformed and loose or cannot be pushed, so that the installation is not convenient).

[0055] When the above installation method is used, a gap with a width of a rectangular tooth slot will be formed between the first and last waterproof units after all the waterproof units are installed, and a continuous waterproof line cannot be formed; based on this, the cover plate connecting plate 5 as shown in Figure 5 is designed; the middle part of the cover plate connecting plate 5 has a protrusion, which serves as a water receiving box; the middle part of the protrusion is connected to the small end of the water-swelling sealing strip A3 through the connecting plate 4. When installed, the cover plate connecting plate 5 with the water-swelling sealing strip A3 and the connecting plate 4 installed thereon is fixed (welded in this example) between the first and last waterproof units, so that two continuous waterproof lines and a continuous water receiving box are formed.

[0057] The construction method of the underground structure waterproof system in the above examples 1 or 2 is given.

[0058] S1, when pouring the underground structure, the fixed clamping plate 1 is poured together with the fixed plate anchor bar 2 and the underground structure reinforcement cage;

[0059] S2, the water-swelling sealing strip B7 is pasted on the fixed clamping plate 1;

[0060] S3, the waterproof unit composed of the factory prefabricated water-swelling sealing strip A3, the connecting plate 4 and the cover plate 6 is installed in place, the water-swelling sealing strip A3 is inserted into the deformation joint, and the cover plate 6 is clamped with the fixed clamping plate 1 for fixation, and the compression bolt 8 is further used for compaction.

[0061] S4, the cover plate connecting plate 5 connected with the water-swelling sealing strip A3 and the connecting plate 4 is used to connect the adjacent two waterproof units with gaps by welding, so as to form a continuous waterproof line and a water receiving box.
