Description

Technical Field

[0001] This utility model relates to the field of geotechnical materials technology, and in particular to non-destructive composite geomembranes. Background Technology

[0002] Composite geomembrane is a geosynthetic material widely used in engineering fields such as water conservancy, transportation, and environmental protection. It mainly plays the roles of seepage prevention, isolation, and reinforcement. In the actual construction and laying process, in order to adapt to different terrains and coverage area requirements, it is often necessary to cut the standard-sized composite geomembrane.

[0003] However, after cutting, the cut surface of existing composite geomembranes is often directly exposed. Since composite geomembranes are composed of multiple layers of materials such as membrane material and geotextile, the exposed cut surface may cause the membrane and fabric to separate during handling, installation and stress. This not only damages the integrity of the material, but also makes it difficult to seal the joints, seriously affecting the seepage prevention effect and construction quality of the project.

[0004] Furthermore, in actual applications of composite geomembranes, the environments they face are often quite harsh. Sharp stones or plant roots that have not been cleaned up are often present on the laying surface, which can puncture the membrane and cause leakage. At the same time, some geomembranes need to be exposed to the outdoors for a long time. High temperatures can accelerate the aging and degradation of the material, damaging the physical properties of the geomembrane. Under certain geological conditions, soil settlement or displacement can generate large tensile stresses. If the geomembrane itself has insufficient tensile strength or lacks a reinforcing structure, it will be torn and destroyed. Existing geomembranes often have only one function and lack a structural design that can simultaneously solve the problem of cutting and sealing as well as provide comprehensive protection such as puncture resistance, heat insulation, and tensile strength.

[0005] Therefore, this invention proposes a non-destructive composite geomembrane to address the shortcomings of existing technologies. Utility Model Content

[0006] In view of the problems in the existing composite geomembrane technology, such as the exposed cut during cutting and installation leading to membrane separation, and the lack of comprehensive protection against sharp objects, high temperature and tensile force during use, resulting in damage, this utility model aims to provide a non-damaging composite geomembrane with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a non-damaging composite geomembrane, comprising: a composite geomembrane body, a preventive mechanism disposed at the right end of the composite geomembrane body, and a protective mechanism embedded in the interior of the composite geomembrane body.

[0008] The protective mechanism includes a position groove 1 inside the composite geomembrane, a scratch-resistant cloth fixedly connected inside the position groove 1, a position groove 2 inside the scratch-resistant cloth, a heat insulation film fixedly connected to the upper end of the position groove 2, and a metal mesh fixedly connected to the lower end of the position groove 2.

[0009] Furthermore, the prevention mechanism includes a quick-sealing block disposed on the cut surface of the composite geomembrane, and a groove is provided in the middle of the left end of the quick-sealing block, and the cut surface of the composite geomembrane is slidably engaged with the inside of the groove.

[0010] Preferably, the prevention mechanism further includes guide grooves at the upper and lower ends of the outer side of the composite geomembrane, and the upper and lower ends of the quick-sealing block are provided with structures that match the guide grooves, and the quick-sealing block can slide along the guide grooves.

[0011] Preferably, a protrusion is fixedly connected to the outer side of the anti-scratch cloth, and multiple grooves are provided on the inner wall of the position groove, with the protrusion engaging with the grooves.

[0012] Preferably, the heat insulation film is made of high-temperature resistant heat-insulating aluminum foil.

[0013] Preferably, the metal mesh is a stainless steel wire mesh, and the metal mesh is laid flat at the bottom of the second position groove.

[0014] This utility model has the following beneficial effects: 1. This utility model solves the problem of membrane separation caused by exposed cut surfaces after cutting of composite geomembrane in the prior art by setting a quick-sealing block with a sliding groove. The quick-sealing block slides and engages with the cut surface of the composite geomembrane. It achieves the effect of effectively covering and sealing the cut surface, preventing structural delamination, and facilitating on-site construction. 2. This utility model solves the problems of composite geomembranes being punctured by sharp objects, damaged by high temperatures, or torn by external forces by setting a protective mechanism inside the composite geomembrane body. The protective mechanism integrates anti-scratch cloth, heat insulation film and metal mesh.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0018] Example: Please refer to Figures 1 to 4 This utility model provides a non-damaging composite geomembrane, which aims to solve the problems in the prior art where the cut of the composite geomembrane is exposed during cutting and installation, leading to separation of the membrane and fabric, and the sliding is unstable during fixing. In use, it lacks comprehensive protection against sharp objects, high temperature and tensile force, resulting in damage.

[0019] Please refer to Figure 1 , Figure 2 and Figure 3 The non-damaging composite geomembrane includes a composite geomembrane body 1, a prevention mechanism 2 located at the right end of the composite geomembrane body 1, and a protective mechanism 3 embedded inside the composite geomembrane body 1. The protective mechanism 3 is a multi-layer composite structure. The protective mechanism 3 includes a position groove 301 opened inside the composite geomembrane body 1, an anti-scratch cloth 302 fixedly connected inside the position groove 301, a second position groove 303 opened inside the anti-scratch cloth 302, and a heat insulation film 304 fixedly connected to the upper end of the second position groove 303. A metal mesh 305 is fixedly connected to the lower end of the inner side of the groove 303. The anti-scratch cloth 302 is used to prevent external sharp objects from piercing the composite geomembrane 1. The heat insulation film 304 is used to block external high temperature. The metal mesh 305 is used to enhance tensile strength. The prevention mechanism 2 includes a quick-sealing block 202 set on the cut surface of the composite geomembrane 1. A sliding groove 203 is opened in the middle of the left end of the quick-sealing block 202. The cut surface of the composite geomembrane 1 is slidably engaged in the inside of the sliding groove 203 to cover and seal the cut surface and prevent the membrane from separating.

[0020] Please refer to Figure 3 and Figure 4The following is a detailed description of the cooperative structure of the prevention mechanism 2 and the protection mechanism 3. To achieve stable installation of the quick-sealing block 202, the prevention mechanism 2 also includes guide grooves 201 at the upper and lower ends of the outer side of the composite geomembrane 1. The upper and lower ends of the quick-sealing block 202 are provided with structures that match the guide grooves 201. The quick-sealing block 202 can slide along the guide grooves 201. This guiding structure ensures that the quick-sealing block 202 can be stably and accurately aligned when installed on the cut surface of the composite geomembrane 1, preventing installation deviation. At the same time, to further enhance the fixing firmness, the outer side of the anti-scratch cloth 302 of the protection mechanism 3 is fixedly connected with a protrusion 205. Corresponding to the protrusion 205, the inner wall of the position groove 301 is provided with multiple grooves 204. In the assembled state, the protrusion 205 and the groove 204 are engaged. This concave-convex cooperation structure increases the connection firmness between the anti-scratch cloth 302 and the composite geomembrane 1 by shape locking, effectively avoiding unstable fixing or relative sliding caused by smooth surface.

[0021] As a preferred embodiment, please refer to Figure 1 and Figure 4 The prevention mechanism 2 also includes guide grooves 201 opened at the upper and lower ends of the outer side of the composite geomembrane 1. The upper and lower ends of the quick-sealing block 202 are provided with structures that match the guide grooves 201. The quick-sealing block 202 can slide along the guide grooves 201 through sliding connection with the guide grooves 201, which facilitates the alignment and advancement of the quick-sealing block 202 when it is installed on the cutting surface.

[0022] As another preferred embodiment, please refer to Figure 3 and Figure 4 To enhance the fixing effect of the anti-scratch cloth 302, a protrusion 205 is fixedly connected to the outer side of the anti-scratch cloth 302. Corresponding to the protrusion 205, multiple grooves 204 are opened on the inner wall of the position groove 301. The protrusion 205 and the groove 204 are engaged and matched. This structure increases the connection between the anti-scratch cloth 302 and the composite geomembrane 1 and prevents relative sliding.

[0023] As a preferred embodiment, please refer to Figure 3 The heat insulation membrane 304 is made of high-temperature resistant heat insulation aluminum foil material. This material can effectively reflect and block external heat, preventing high temperature from causing structural damage to the composite geomembrane 1.

[0024] As a preferred embodiment, please refer to Figure 3 Metal mesh 305 is stainless steel wire mesh. Metal mesh 305 is laid flat at the bottom of position groove 2 303. Utilizing the high tensile strength of stainless steel wire mesh, it provides additional tear resistance to the composite geomembrane 1, preventing it from breaking due to external pulling.

[0025] Working principle: When it is necessary to cut and seal the composite geomembrane 1, the staff uses the prevention mechanism 2. The quick-sealing block 202 can slide along the guide groove 201 opened at the upper and lower ends of the outer side of the composite geomembrane 1, and slide the cut surface of the composite geomembrane 1 into the sliding groove 203 in the middle of the left end of the quick-sealing block 202. Through the covering of the quick-sealing block 202, the cut surface is covered and sealed, thus avoiding the exposure of the cut after cutting and preventing the membrane from separating. When the composite geomembrane 1 is laid and used, the internal protective mechanism 3 provides comprehensive protection. Position groove 301 is opened inside the composite geomembrane 1. The anti-scratch cloth 302 inside the position groove 301 is used to prevent sharp objects on the laying surface from puncturing the composite geomembrane 1. In the position groove 303 opened inside the anti-scratch cloth 302, the heat insulation film 304 at the upper end of the position groove 303 is used to block the external high temperature and prevent the high temperature from damaging the structure of the composite geomembrane 1. The metal mesh 305 at the lower end of the position groove 303 provides high tensile strength when the composite geomembrane 1 is subjected to external tension, preventing the composite geomembrane 1 from being torn and damaged. During the installation and fixing process, the protrusion 205 on the outer side of the anti-scratch cloth 302 engages with the groove 204 on the inner wall of the position groove 301. Through this interlocking of concave and convex shapes, the anti-scratch cloth 302 and the composite geomembrane 1 are firmly fixed, avoiding slippage and instability.
