Description

Technical Field

[0001] The invention relates to the technical field of building waterproof coiled materials, and in particular discloses a building waterproof coiled material with leakage positioning function and a tunnel water leakage monitoring system. Background Art

[0002] The construction of tunnels is developing in the direction of deep burial, large span, complex structure and diverse functions, which is a difficult test for tunnel waterproofing. Long-term dryness in the tunnel is one of the important conditions to ensure the normal operation of the tunnel. If the tunnel leakage can be discovered and sealed at the first time, it can not only improve the service life of the tunnel, but also effectively avoid accidents such as landslides.

[0003] Existing tunnels generally use composite linings, that is, a waterproof isolation layer is set between the support layer and the concrete lining. The waterproof layer uses a polymer waterproof membrane, which is not only waterproof, but also isolates and lubricates the initial sprayed concrete and the secondary lining cast concrete, reducing the constraint of the initial support sprayed concrete on the secondary lining concrete, effectively avoiding cracks in the cast concrete, and improving the anti-seepage capacity of the secondary lining concrete. The waterproof layer is usually composed of a cushion layer and a waterproof board, among which the waterproof board is the core of tunnel waterproofing technology, and the manufacturing material is generally polypropylene. In tunnel waterproofing, if there is a leak in the waterproof board, the initial support layer, the waterproof board and the secondary lining are not tightly attached, and the leakage will fill the gap between the waterproof board and the secondary lining, making the tunnel's waterproof system ineffective, which will not only greatly reduce the service life of the tunnel, but also easily cause danger.

[0004] At present, the inspection of leaks mainly adopts manpower, and the leaks are blocked after being found. However, this method is not only time-consuming and labor-intensive, but also difficult to find some smaller leaks, which poses a safety hazard. At present, there is an urgent need for a system that can accurately monitor leaks, which is low-cost and has a wide range of applications. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, the present invention provides a building waterproofing membrane with leakage locating function and a tunnel water leakage monitoring system to solve the problem of timely monitoring of tunnel water leakage points.

[0006] To achieve the above object, the technical solution of the present invention is:

This facilitates the connection between two adjacent layers when multiple layers of the building waterproof membrane with leakage locating function are arranged, and can ensure that the building waterproof membrane with leakage locating function fits the support of the tunnel.

[0014] Preferably, the upper hinge seat is arranged outside the isolation film; the lower hinge seat is arranged outside the tire base layer. This facilitates the connection between two adjacent building waterproof coiled materials with leakage positioning functions.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Embodiment 1

[0035] As Figures 1-4As shown in the figure, a building waterproofing coil with a leakage positioning function includes a base layer 1, an anti-sticking layer 4 and an isolation film 5. It is characterized in that a protective layer is provided between the bottom surface of the anti-sticking layer 4 and the top surface of the base layer 1; the protective layer includes an anti-aging layer 2 and a buffer layer 3, which can increase the service life; the anti-aging layer 2 is arranged on the top surface of the base layer 1; the buffer layer 3 is arranged on the top surface of the anti-aging layer 2; a longitudinal wire 6 is arranged inside the buffer layer 3. An isolation film 5 is arranged outside the anti-sticking layer 4; several transverse wires 7 are arranged inside the base layer 1; a sensing component is arranged at the intersection of the longitudinal wire 6 and the transverse wire 7; the sensing component is used to detect whether there is water leakage. The longitudinal wire 6 and the transverse wire 7 have the same structure, both including a wire and an insulating layer coated outside the wire, and several notches are arranged on the insulating layer to facilitate the setting of the sensing component; the notches are arranged at the intersection of the longitudinal wire 6 and the transverse wire 7 and are in contact with the sensing component. The longitudinally and transversely staggered wires 6 and 7 can cover a large area, and the sensing component is used to detect the resistance change caused by water leakage at the intersection of the two, so as to monitor the water leakage point in time.

[0036] In the above setting, the sensing component includes a fixed frame 8 and a water-absorbing conductive material 9 arranged inside the fixed frame 8; the fixed frame 8 is integrally arranged in a cuboid frame structure; the base layer 1 is arranged at the bottom surface of the fixed frame 8; the anti-sticking layer 4 is arranged on the top surface of the fixed frame 8. The fixed frame 8 includes a top plate 801 and a bottom plate 802; the top plate 801 and the bottom plate 802 are arranged at intervals and are parallel to each other; the corners of the top plate 801 and the bottom plate 802 are connected by support rods 803; the water-absorbing conductive material 9 is arranged between the top plate 801 and the bottom plate 802, which further ensures the stability of the setting of the water-absorbing conductive material 9 and ensures the monitoring accuracy of the resistance change at the intersection of the longitudinal wire 6 and the transverse wire 7. Two upper circular ring plates 804 are fixedly arranged on the bottom surface of the top plate 801; the two upper circular ring plates 804 are coaxially arranged; two lower circular ring plates 805 are fixedly arranged on the top surface of the bottom plate 802; the two lower circular ring plates 805 are coaxially arranged; the axial directions of the upper circular ring plate 804 and the lower circular ring plate 805 are perpendicular to each other; several blocking rods 806 are arranged between the support rods 803. The setting of the upper circular ring plate 804 and the lower circular ring plate 805 ensures the stability of the fixed frame 8 on the longitudinal wire 6 and the transverse wire 7. The setting of the blocking rods 806 further ensures the stability of the setting of the water-absorbing conductive material 9. The setting of the water-absorbing conductive material 9 can ensure that the resistance becomes smaller after absorbing water, and can timely monitor the resistance change at the intersection of the longitudinal wire 6 and the transverse wire 7.

[0037] Among them, the base layer 1 is a polyethylene or polypropylene waterproof board; the anti-sticking layer 4 is a butyl rubber replacing asphalt. The water-absorbing conductive material 9 is a polymer-based waterborne conductive material, which is a conductive polymer.

[0038] Embodiment 2

[0039] As Figures 5-7As shown, the difference from Embodiment 1 is that two layers of the building waterproof coiled material with leakage positioning function are provided; to facilitate the connection between the two layers, on the basis of Embodiment 1, an upper hinge seat 807 is fixedly arranged on the top surface of the top plate 801; a lower hinge seat 808 is fixedly arranged on the bottom surface of the bottom plate 802; the upper hinge seat 807 is arranged outside the isolation film 5; the lower hinge seat 808 is arranged outside the carcass layer 1; the upper hinge seat 807 of one fixing frame 8 can be hinged to the lower hinge seat 808 of another fixing frame 8 by a pin shaft 11, which can ensure that the two layers of the building waterproof coiled material with leakage positioning function fit the support 12 of the tunnel.

The processing terminal of this tunnel leakage monitoring system can receive the resistance change (decrease or directly become zero resistance) of the water-absorbing and conductive material and judge the water seepage point.

[0042] When water leakage occurs, it will cause the water-absorbing and conductive material 9 in the sensing component of the building waterproof coiled material with leakage positioning function to absorb water and the resistance to decrease. The signal detection and conversion component 10 sends the detected resistance change information to the processing terminal 14 for processing, and then the specific position of the leakage point is obtained according to the resistance change corresponding to the serial numbers of the transverse wire 6 and the longitudinal wire 7.

[0043] Although the present invention has been described in detail by referring to the accompanying drawings and in combination with the preferred embodiments, the present invention is not limited thereto.

Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
