Description

Technical Field

[0001] The present application relates to the technical field of ground waterproofing, and in particular to a pre-laid reverse-adhesive waterproofing structure for underground engineering. Background Art

[0002] In engineering construction, the ground needs to be waterproofed in advance. There are many traditional treatment methods, such as casting concrete or laying waterproof membranes. The former needs to be demolished if the engineering is modified later, which is time-consuming and laborious. Although the latter is easier to dismantle, it is not easy to lay and is prone to damage. The waterproof membrane will be contaminated after use and is difficult to reuse or recycle. It is usually discarded as waste, which easily causes environmental pollution. Prefabricated panels are also used in the prior art, but in order to ensure the waterproof ability, glue is filled between the prefabricated panels, which is also time-consuming and laborious to dismantle. Summary of the invention

[0003] The purpose of the present application is to provide a pre-laid reverse-adhesive waterproof structure for underground engineering which is easy to disassemble and assemble and can be reused.

[0004] To achieve the above objectives, the present application provides a pre-laid reverse-adhesive waterproof structure for underground projects: comprising a rectangular plate, wherein the rectangular plate has a first lower card plate and a second upper card plate on a pair of opposite sides, the upper surface of the first lower card plate is flush with the lower surface of the second upper card plate, and the rectangular plate has a second lower card plate and a first upper card plate on another pair of opposite sides, the upper surface of the second lower card plate is flush with the lower surface of the first upper card plate, and the second lower card plate has an extension plate at one end facing the second upper card plate, and the end of the extension plate is flush with the side of the second upper card plate, so that adjacent card plates can fit tightly together.

[0005] Preferably, an upper sealing strip is fixedly connected to the upper surface of the first lower card plate, and a lower sealing groove is provided on the lower surface of the second upper card plate, which is suitable for fitting with the upper sealing strip of the other anti-adhesive waterproof structure to prevent liquid from overflowing from the gap.

[0006] Preferably, the extension direction of the upper sealing strip is parallel to the length direction of the first lower card board, and the two ends of the upper sealing strip are flush with the two ends of the first lower card board; the extension direction of the lower sealing groove is parallel to the length direction of the second upper card board, and the two ends of the lower sealing groove are flush with the two ends of the second upper card board, completing the missing part of the reverse-adhesive waterproof structure after splicing.

[0007] Preferably, an upper sealing groove is provided on the upper surface of the second lower card plate, and a lower sealing strip is fixedly connected to the lower surface of the first upper card plate, which is suitable for fitting with the upper sealing groove of another reverse-adhesive waterproof structure, and is also used to achieve water blocking.

[0008] Preferably, the extension direction of the upper sealing groove is parallel to the length direction of the second lower card plate, and the two ends of the upper sealing groove are flush with the end of the second lower card plate and the end of the extension plate respectively; the extension direction of the lower sealing strip is parallel to the length direction of the first upper card plate, and the two ends of the lower sealing strip are flush with the two ends of the first upper card plate, so that the sealing strip can completely intercept the splicing gap.

[0009] Preferably, the lower surface of the rectangular plate has ribs, and the side of the first lower card plate facing away from the rectangular plate has a downwardly extending anti-slip edge, and the length direction of the ribs is perpendicular to the length direction of the anti-slip edge, so that the anti-sticking waterproof structure will not move after it is close to the ground.

[0010] As a preference, the thickness of the first lower card plate and the second upper card plate are both half of the thickness of the rectangular plate, and except for the fitting surfaces, the other surfaces of the upper and lower card plates are flush with the rectangular plate.

[0011] Preferably, the thickness of the second lower card plate and the first upper card plate are both half of the thickness of the rectangular plate. Similarly, except for the fitting surfaces, the other surfaces of the upper and lower card plates are flush with the rectangular plate.

[0012] Compared with the prior art, the beneficial effects of this application are:

[0013] (1) By setting a cardboard structure on the side of the prefabricated board and reasonably setting the direction of each cardboard, a step structure that blocks water flow is formed between the prefabricated boards, which has good laying stability and water blocking properties. The step structure is easier to align during the laying process and is convenient for installation;

[0014] (2) There is a sealing strip structure between the joints, which can have a very good anti-overflow performance without using glue. Therefore, the pre-laid reverse-adhesive waterproof structure is easy to disassemble without destroying the assembly unit and can be recycled and reused. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0025] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0026] like Figure 1-6The pre-laid anti-adhesive waterproof structure for underground engineering shown in the figure includes a rectangular plate 1. In this embodiment, the upper and lower surfaces of the rectangular plate 1 are both squares. The thickness of the rectangular plate 1 is not large, so the sides are all long rectangular strips. The lower surface of the rectangular plate 1 has ribs 101, which can be embedded in the muddy ground to prevent the rectangular plate 1 from moving in a direction perpendicular to the ribs 101. The rectangular plate 1 has a first lower card plate 2 and a second upper card plate 5 on a pair of opposite sides, respectively, and the two have a fitting structure, wherein the first lower card plate 2 has a downwardly extending anti-movement card edge 202 on the side facing away from the rectangular plate 1, so the anti-movement card edge 202 can also be embedded in the muddy ground to prevent the anti-movement waterproof structure from moving in a direction perpendicular to the anti-movement card edge 202. The length direction of the ribs 101 is perpendicular to the length direction of the anti-movement card edge 202. Therefore, after the anti-movement waterproof structure is attached to the ground, it is difficult to move in any direction and has a high attachment stability.

[0027] The upper surface of the first lower card plate 2 is flush with the lower surface of the second upper card plate 5, and the thickness of the first lower card plate 2 and the second upper card plate 5 is half of the thickness of the rectangular plate 1. In fact, the lower surface of the first lower card plate 2 is flush with the lower surface of the rectangular plate 1, and the upper surface of the second upper card plate 5 is flush with the upper surface of the rectangular plate 1. The upper surface of the first lower card plate 2 is fixedly connected with an upper sealing strip 201, and the extension direction of the upper sealing strip 201 is parallel to the length direction of the first lower card plate 2. Both ends of the upper sealing strip 201 are parallel to the length direction of the first lower card plate 2. The two ends of the first lower card plate 2 are flush; a lower sealing groove 501 is opened on the lower surface of the second upper card plate 5, and the extension direction of the lower sealing groove 501 is parallel to the length direction of the second upper card plate 5. The two ends of the lower sealing groove 501 are flush with the two ends of the second upper card plate 5, and just fit with the other upper sealing strip 201 of the reverse-adhesive waterproof structure. The upper sealing strip 201 is made of soft and elastic waterproof material, such as rubber. After fitting with the lower sealing groove 501, it will have an interference fit and close contact, and has a good water-blocking effect.

[0028] The rectangular plate 1 has a second lower card board 3 and a first upper card board 4 on another pair of opposite side surfaces, respectively. Therefore, the length direction of the first lower card board 2 and the second upper card board 5 is perpendicular to the length direction of the first lower card board 2 and the second upper card board 5. Similarly, the upper surface of the second lower card board 3 is flush with the lower surface of the first upper card board 4, and the thickness of the second lower card board 3 and the first upper card board 4 is half of the thickness of the rectangular plate 1. Therefore, the lower surface of the second lower card board 3 is flush with the lower surface of the rectangular plate 1, and the upper surface of the second upper card board 5 is flush with the upper surface of the rectangular plate 1. The second lower card board 3 has an extension plate 302 at one end facing the second upper card board 5, and the end of the extension plate 302 is flush with the side surface of the second upper card board 5, which is used to make up for the length deficiency of the second lower card board 3, so that the reverse-adhesive waterproof structure can be completely assembled after splicing. The ground is covered without being exposed. An upper sealing groove 301 is provided on the upper surface of the second lower card plate 3. The extension direction of the upper sealing groove 301 is parallel to the length direction of the second lower card plate 3. The two ends of the upper sealing groove 301 are flush with the end of the second lower card plate 3 and the end of the extension plate 302 respectively; a lower sealing strip 401 is fixedly connected to the lower surface of the first upper card plate 4. The extension direction of the lower sealing strip 401 is parallel to the length direction of the first upper card plate 4. The two ends of the lower sealing strip 401 are flush with the two ends of the first upper card plate 4, which just fits with the upper sealing groove 301 of the other anti-adhesive waterproof structure. Similarly, the lower sealing strip 401 is also made of elastic and soft waterproof material, which fits tightly with the upper sealing groove 301, and plays a good water-blocking role to prevent water from flowing through the splicing gap of the anti-adhesive waterproof structure.

[0029] Working principle: as attached Figure 5 and 6 After the waterproofing is finished, the second upper and second lower plates 3 are put on the second lower plate 3 of the anti-adhesive waterproof structure, and the second lower plates 3 are put on the second lower plate 3 of the anti-adhesive waterproof structure.
