Description

Technical Field

[0001] This utility model relates to the field of lining waterproofing testing technology, and in particular to a structure for testing the relaxation of lining waterproofing board. Background Technology

[0002] During tunnel construction, in the tunnel exit section located in a bedrock fissure water-rich area with slate interbedded with metamorphic sandstone, sudden or concentrated water inrushes may occur during tunnel excavation. Therefore, the quality of waterproofing and drainage construction is a key focus of tunnel construction. Currently, under the above conditions, frequent seepage and inrushes at the tunnel's initial support face and difficulty in controlling the flatness of the initial support face lead to poor quality of waterproofing membrane installation and voids behind the lining. During tunnel construction, these problems are generally solved by grouting and water plugging at the initial support face, as well as spraying, but the quality of the waterproofing membrane installation looseness still cannot be effectively controlled. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies in which the quality of the slack of the waterproofing membrane during tunnel construction in bedrock fissure water-weak and water-rich areas cannot be effectively controlled, and to provide a structure for detecting the slack of the lining waterproofing membrane.

[0004] In a first aspect, the present invention provides a structure for detecting the relaxation degree of a waterproof lining, comprising: A bow seat, wherein a first through hole is provided in the middle of the bow seat; A reference component, connected between the two ends of the bow seat, has a reference surface, and the opening direction of the first through hole is perpendicular to the reference surface; The measuring rod slides into the first through hole and is adapted to the first through hole.

[0005] The lining waterproofing membrane relaxation detection structure described in this application involves placing the two ends of the arch support against any two positions of the waterproofing membrane during construction. A first through hole is provided in the middle of the arch support, through which a measuring rod passes and slides. A reference member is connected between the two ends of the arch support, and a reference surface is provided on the reference member as a reference between the two ends of the arch support. The opening direction of the first through hole is perpendicular to the reference surface. Using the reference surface as a reference, the relaxation of the waterproofing membrane can be confirmed by observing the length of the measuring rod end protruding from the reference surface along the opening direction of the first through hole. This lining waterproofing membrane relaxation detection structure improves the construction quality of the waterproofing membrane, avoids rework of the waterproofing membrane later, reduces the frequency of voids behind the lining, and saves the cost of waterproofing membrane rework and subsequent grouting with formwork.

[0006] More specifically, during construction, when using the lining waterproofing membrane relaxation detection structure described in this application, the location where the relaxation of the waterproofing membrane may exceed the limit can be visually identified. The fixed ends of the bow seat are placed against the two convex surfaces of the waterproofing membrane, and a reference is formed between the two fixed ends by a reference component. Holding the bow seat, the relaxation of the waterproofing membrane is measured by sliding a graduated measuring rod relative to the first through hole. During the installation of the waterproofing membrane, the lining waterproofing membrane relaxation detection structure described in this application is used continuously to check the installation quality, ensuring that the convex and concave surfaces of the waterproofing membrane meet the requirement of D / L < 1 / 20 [D is the concave depth between the convex surfaces, L < 1.0m, L is the distance between the two convex surfaces], thereby improving the installation quality of the waterproofing membrane. In on-site construction, using the lining waterproofing membrane relaxation detection structure described in this application significantly improves the flatness of the waterproofing membrane installation, greatly reduces the voids behind the lining, and significantly reduces the cost of grouting with formwork.

[0007] Preferably, the bow seat includes a bow arm portion and a boom portion connected to both ends of the bow arm portion. The bow arm portion is arranged along the length direction of the reference member, and the boom portion is arranged along the opening direction of the first through hole. The reference member is connected to the boom portion.

[0008] Preferably, the bow arm includes a rectangular tube, which is hollow and forms the first through hole. Two sections of the rectangular tube are connected to grips, the cross-section of which is circular. The end of the grip away from the rectangular tube is connected to a first arm, which is integrally formed with the boom portion on the same side.

[0009] Using a rectangular tube makes the first through hole a rectangular hole (including square holes), so that the measuring rod can only slide with the first through hole and cannot rotate circumferentially, which facilitates practicality, reduces wear between the measuring rod and the first through hole, effectively ensures the fit between the measuring rod and the first through hole, and reduces the angular deviation when the measuring rod moves.

[0010] Preferably, the first arm has a first blind hole, the grip portion extends into the first blind hole and slides with the first blind hole, and a locking member is provided between the first arm and the grip, the locking member is used to fix the first arm and the grip relative to each other.

[0011] By sliding the lever with the first blind hole, the range of movement of the probe along the length of the reference piece is expanded, thereby increasing the detection range of the probe.

[0012] Preferably, the reference member is provided with a first scale portion to measure the displacement of the measuring rod relative to the center position.

[0013] Preferably, the end face of the boom portion away from the bow portion is the first end face, and the reference surface is flush with the first end face. This facilitates the installation accuracy of the reference component.

[0014] Preferably, the measuring rod has a second end face, which is arranged parallel to the reference plane.

[0015] Preferably, a first adjusting block is detachably connected to the first end face, and the side of the first adjusting block away from the first end face is spherical.

[0016] Preferably, a second adjusting block is detachably connected to the second end face, and the side of the second adjusting block away from the second end face is spherical.

[0017] Preferably, along the opening direction of the first through hole, the thickness D1 of the portion of the first adjusting block located on the outer side of the boom is equal to the thickness D2 of the portion of the second adjusting block located on the outer side of the measuring rod.

[0018] By setting a first adjusting block and a second adjusting block, with the side of the first adjusting block away from the first end face being spherical and the side of the second adjusting block away from the second end face being spherical, scratches on the waterproof membrane by the bow seat and the measuring rod can be avoided. At the same time, if the first adjusting block or the second adjusting block is worn after a period of use, the first adjusting block or the second adjusting block can be replaced separately without replacing the entire lining waterproof membrane relaxation detection structure described in this application, thereby saving construction costs.

[0019] Preferably, a first threaded hole is provided on the first end face, the first adjusting block includes a first threaded rod and a first mushroom head connected together, the side of the first mushroom head away from the first threaded rod is spherical, and the first threaded hole is threadedly connected to the first threaded rod.

[0020] When wear occurs later, a first shim can be set between the first end face and the first mushroom head. The first shim is sleeved on the first threaded rod to adjust the thickness D1 of the first adjusting block located on the outer part of the boom.

[0021] Preferably, a second threaded hole is provided on the second end face, the second adjusting block includes a second threaded rod and a second mushroom head connected together, the side of the second mushroom head away from the second threaded rod is spherical, and the second threaded hole is threadedly connected to the second threaded rod.

[0022] When wear occurs later, a second shim can be set between the second end face and the second mushroom head. The second shim is sleeved on the second threaded rod to adjust the thickness D2 of the second adjusting block located on the outer part of the measuring rod.

[0023] Preferably, the second mushroom head has the same thickness as the first mushroom head.

[0024] Preferably, the measuring rod has a second scale section along its length, with the second end face as the starting point of the scale. This allows for accurate measurement of the vertical distance between the convex and concave surfaces of the waterproof membrane.

[0025] Compared with the prior art, the beneficial effects of this utility model are as follows: The lining waterproofing membrane relaxation detection structure described in this application involves placing the two ends of the arch support against any two positions of the waterproofing membrane during construction. A first through hole is provided in the middle of the arch support, through which a measuring rod passes and slides. A reference member is connected between the two ends of the arch support, and a reference surface is provided on the reference member as a reference between the two ends of the arch support. The opening direction of the first through hole is perpendicular to the reference surface. Using the reference surface as a reference, the relaxation of the waterproofing membrane can be confirmed by observing the length of the measuring rod end protruding from the reference surface along the opening direction of the first through hole. This lining waterproofing membrane relaxation detection structure improves the construction quality of the waterproofing membrane, avoids rework of the waterproofing membrane later, reduces the frequency of voids behind the lining, and saves the cost of waterproofing membrane rework and subsequent grouting with formwork.

[0041] Example 1 like Figure 1-5 As shown, this utility model provides a structure for detecting the relaxation degree of a waterproof lining, comprising: Bow seat 1, wherein a first through hole 11 is provided in the middle part; The reference component 2 is connected between the two ends of the bow seat 1 and has a reference surface 21. The opening direction of the first through hole 11 is perpendicular to the reference surface 21. The measuring rod 3 is slidably engaged with the first through hole 11 and is adapted to the first through hole 11.

[0042] The lining waterproofing membrane relaxation detection structure described in this application involves placing the two ends of the arch support 1 against any two positions of the waterproofing membrane during construction. A first through hole 11 is provided in the middle of the arch support 1. A measuring rod 3 passes through the first through hole 11 and slides in cooperation with it. A reference member 2 is connected between the two ends of the arch support 1. A reference surface 21 is provided on the reference member 2 as a reference between the two ends of the arch support 1. The opening direction of the first through hole 11 is perpendicular to the reference surface 21. Using the reference surface 21 as a reference, the relaxation of the waterproofing membrane can be confirmed by observing the length of the measuring rod 3 protruding from the reference surface 21 along the opening direction of the first through hole 11. The lining waterproofing membrane relaxation detection structure described in this application provides auxiliary detection of the relaxation of the waterproofing membrane, improves the construction quality of the waterproofing membrane, avoids rework of the waterproofing membrane later, reduces the frequency of voids behind the lining, and saves the cost of waterproofing membrane rework and subsequent grouting with formwork.

[0043] More specifically, during construction, when using the lining waterproofing membrane relaxation detection structure described in this application, the location where the relaxation of the waterproofing membrane may exceed the limit can be visually identified. The fixed ends of the bow seat 1 are placed against the two convex surfaces of the waterproofing membrane, and a reference is formed between the two fixed ends by a reference piece 2. Holding the bow seat 1, the relaxation of the waterproofing membrane is measured by sliding a graduated measuring rod 3 relative to the first through hole 11. During the installation of the waterproofing membrane, the lining waterproofing membrane relaxation detection structure described in this application is used continuously to check the installation quality, ensuring that the convex and concave surfaces of the waterproofing membrane meet the requirement of D / L < 1 / 20 [D is the depth of concavity between convex surfaces, L < 1.0m, L is the distance between the two convex surfaces], thereby improving the installation quality of the waterproofing membrane. Using the lining waterproofing membrane relaxation detection structure described in this application during on-site construction significantly improves the flatness of the waterproofing membrane installation, greatly reduces the voids behind the lining, and significantly reduces the cost of grouting with formwork.

[0044] In one or more embodiments, the bow base 1 includes a bow arm portion 12 and a boom portion 13 connected to both ends of the bow arm portion 12. The bow arm portion 12 is arranged along the length direction of the reference member 2, and the boom portion 13 is arranged along the opening direction of the first through hole 11. The reference member 2 is connected to the boom portion 13.

[0045] In one or more embodiments, the boom portion 12 includes a rectangular tube 121, which is hollow and forms the first through hole 11. Two ends of the rectangular tube 121 are connected to grips 122, which have a circular cross-section for easy gripping by construction workers. The end of the grip 122 away from the rectangular tube 121 is connected to a first arm 123, which is integrally formed with the boom portion 13 on the same side.

[0046] Using a rectangular tube 121 makes the first through hole 11 a rectangular hole (including a square hole), so that the measuring rod 3 can only slide with the first through hole 11 and cannot rotate circumferentially, which is convenient for practical use, reduces wear between the measuring rod 3 and the first through hole 11, effectively ensures the fit between the measuring rod 3 and the first through hole 11, and reduces the angular deviation when the measuring rod 3 moves.

[0047] In one or more embodiments, a first blind hole is provided on the first arm 123, and the grip 122 extends into the first blind hole and slides with the first blind hole. A locking member 124 is provided between the first arm 123 and the grip 122, and the locking member 124 is used to fix the first arm 123 and the grip 122 relative to each other.

[0048] By sliding the lever 122 with the first blind hole, the range of movement of the measuring rod 3 along the length of the reference member 2 is expanded, thereby expanding the detection range of the measuring rod 3.

[0049] In one or more embodiments, the reference member 2 is provided with a first scale portion 22 to measure the displacement of the measuring rod 3 relative to the center position.

[0050] In one or more embodiments, the end face of the boom portion 13 away from the bow portion 12 is a first end face 14, and the reference surface 21 is flush with the first end face 14. This is to facilitate the installation accuracy of the reference member 2 as a reference.

[0051] In one or more embodiments, the measuring rod 3 has a second end face 31, which is arranged parallel to the reference surface 21.

[0052] In one or more embodiments, a first adjusting block 19 is detachably connected to the first end face 14, and the side of the first adjusting block 19 away from the first end face 14 is spherical.

[0053] In one or more embodiments, a second adjusting block 30 is detachably connected to the second end face 31, and the side of the second adjusting block 30 away from the second end face 31 is spherical.

[0054] In one or more embodiments, along the opening direction of the first through hole 11, the thickness D1 of the portion of the first adjusting block 19 located outside the boom portion 13 is equal to the thickness D2 of the portion of the second adjusting block 30 located outside the measuring rod 3.

[0055] By setting a first adjusting block 19 and a second adjusting block 30, with the side of the first adjusting block 19 away from the first end face 14 being spherical and the side of the second adjusting block 30 away from the second end face 31 being spherical, scratches on the waterproof membrane by the bow seat 1 and the measuring rod 3 are avoided. At the same time, if the first adjusting block 19 or the second adjusting block 30 is worn after a period of use, the first adjusting block 19 or the second adjusting block 30 can be replaced individually without replacing the entire lining waterproof membrane relaxation detection structure described in this application, thereby saving construction costs.

[0056] In one or more embodiments, a first threaded hole 16 is provided on the first end face 14, and the first adjusting block 19 includes a first threaded rod 17 and a first mushroom head 18 connected to each other. The side of the first mushroom head 18 away from the first threaded rod 17 is spherical, and the first threaded hole 16 is threadedly connected to the first threaded rod 17.

[0057] When wear occurs later, a first shim can be provided between the first end face 14 and the first mushroom head 18. The first shim is sleeved on the first threaded rod 17 to adjust the thickness D1 of the portion of the first adjusting block 19 located on the outer side of the boom portion 13.

[0058] In one or more embodiments, a second threaded hole 33 is provided on the second end face 31, and the second adjusting block 30 includes a second threaded rod 34 and a second mushroom head 35 connected to each other. The side of the second mushroom head 35 away from the second threaded rod 34 is spherical, and the second threaded hole 33 is threadedly connected to the second threaded rod 34.

[0059] When wear occurs later, a second shim can be provided between the second end face 31 and the second mushroom head 35. The second shim is sleeved on the second threaded rod 34 to adjust the thickness D2 of the second adjusting block 30 located on the outer part of the measuring rod 3.

[0060] In one or more embodiments, the second mushroom head 35 has the same thickness as the first mushroom head 18.

[0061] In one or more embodiments, the measuring rod 3 has a second scale portion 32 along its length, with the second end face 31 as the starting point of the scale. This allows for the accurate measurement of the vertical distance between the convex and concave surfaces of the waterproof membrane.

[0062] To address the frequent water seepage and gushing at the tunnel's initial support surface, which makes it difficult to control the surface smoothness and leads to poor waterproofing membrane installation quality and voids behind the lining, this embodiment studies a structure for detecting the relaxation of the waterproofing membrane. Through frequent inspections and rectification during construction, the first-time pass rate of the waterproofing membrane is improved, the construction quality is enhanced, rework is avoided, the frequency of voids behind the lining is reduced, and the costs of rework and subsequent grouting with formwork are saved. Furthermore, it also has the following beneficial effects: 1. This prevents the frequent occurrence of waterproofing membrane failures and rework due to insufficient slack in the membrane.

[0063] 2. The application of the lining waterproofing membrane relaxation detection structure described in this embodiment reduces the void rate behind the lining and improves the lining construction quality.

[0064] 3. The reduction in the lining void rate also reduces the cost of grouting with formwork, which has a positive effect on the construction quality of tunnel waterproofing and drainage and the cost of defect remediation.

[0065] 4. The lining waterproofing membrane relaxation detection structure described in this embodiment is suitable for improving the quality control of drainage and waterproofing construction in water-rich tunnels.

[0066] The lining waterproof membrane relaxation detection structure described in this embodiment has fixed ends 13 at both ends and movable ends 3 in the middle measuring rod 3. The measuring rod 3 has a scale on it, and the flatness of the waterproof membrane is measured by the reciprocating movement of the measuring rod 3.

[0067] During construction, the lining waterproofing membrane relaxation detection structure described in this embodiment is used in conjunction with quality standards and control measures: 1. The overlap width of the waterproof membrane should not be less than 20cm. For waterproof membranes laid in sections, at least 60cm of overlap allowance should be reserved at the edge. The joints of the waterproof membranes should be staggered from the construction joints by more than 1m, with an allowable deviation of -10mm.

[0068] The waterproof membrane's convex and concave surfaces must satisfy the condition D / L < 1 / 20 [D is the depth of the concave surface between the convex surfaces, L is the depth of the concave surface between the convex surfaces].
