Description

Technical Field

[0001] The present invention relates to the technical field of tunnel waterproofing, and more specifically, to a water stop belt positioning and connecting device and a construction method thereof. Background Art

[0002] After the tunnel is excavated and formed, shotcrete for the primary lining needs to be sprayed on the inner wall of the tunnel. After the primary lining concrete is formed, the secondary lining concrete is poured. To ensure the construction quality, the tunnel is divided into multiple sections according to a set length, and the construction is carried out in a sectional manner. During the construction process, construction joints will exist at the joints of two adjacent construction sections. During the pouring process of the secondary lining concrete, each construction section is also constructed in sections. Usually, the tunnel is cylindrical, and each construction section is also cylindrical. The pouring sequence of the secondary lining concrete for each construction section is the lower inverted arch and the upper circular arch, and there is a construction joint at the contact surface between the two. If the above-mentioned construction joints are not properly treated, water leakage may occur during the use of the tunnel.

[0003] To avoid affecting the normal use of the tunnel due to water leakage, a longitudinal water stop belt is arranged in the construction joint between the lower inverted arch and the upper circular arch. Usually, the part of the longitudinal water stop belt below the axis is placed in the end face of the lower inverted arch section, and the part of the longitudinal water stop belt above the axis is placed in the end face of the upper circular arch section. The longitudinal water stop belt is made of rubber material, and water stop ribs that can improve the deformation degree are arranged on the surface of the longitudinal water stop belt. Under the extrusion of the lower inverted arch and the upper circular arch, the longitudinal water stop belt may deform, resulting in the inability to achieve a tight connection between the construction joint between the lower inverted arch and the upper circular arch and the longitudinal water stop belt, and the hidden danger of water leakage still cannot be eliminated. At the same time, a circumferential water stop belt is arranged in the construction joint at the joint of two adjacent construction sections. The circumferential water stop belt includes an upper water stop belt and a lower water stop belt. The upper water stop belt is arranged between the upper circular arches of two adjacent construction sections, and the lower water stop belt is arranged between the inverted arches of two adjacent construction sections and is laid from the side of the previously constructed construction section; after the inverted arch construction is completed, it is necessary to reserve a sufficient length of the lower water stop belt, and then construct the upper circular section while installing the upper water stop belt. The upper water stop belt and the lower water stop belt need to be combined into an integral circular ring, and the lower water stop belt needs to be connected to the longitudinal water stop belt. Because the construction surface at the joint of the longitudinal water stop belt and the lower water stop belt is narrow, the connection difficulty is increased, the connection effect is poor, and the connection effect may be lost over time, and the hidden danger of water leakage cannot be eliminated.

[0004] Therefore, a water stop belt positioning and connecting device and a construction method are needed to solve the above problems. Summary of the Invention

[0005] In view of this, the object of the present invention is to provide a water stop belt positioning and connecting device and a construction method. By using the longitudinal water stop belt positioning and connecting device, the installation difficulty of the longitudinal water stop belt is reduced, the connection difficulty between the longitudinal water stop belt and the circumferential water stop belt is reduced, so that a tight connection is achieved between the construction joint and the water stop belt, and the hidden danger of water leakage is eliminated.

As Figures 1 to 6 shown, the water - stop positioning and connection device includes: an installation mechanism and two groups of connection mechanisms.

[0037] The installation mechanism includes two mounting plates 11, as well as a first connecting member and a first limiting member for locking the relative positions of the two mounting plates 11. The two mounting plates 11 are arranged oppositely and are respectively located at the top and bottom of the longitudinal waterstop 1. A first cavity is provided on the surface of each mounting plate 11 facing the longitudinal waterstop 1. The first cavities of the two mounting plates 11 face each other and enclose a first circumferential limiting cavity that fits the shape of at least a part of the longitudinal waterstop 1.

[0038] Two sets of connection mechanisms are respectively arranged on the opposite sides of the longitudinal waterstop 1. Each connection mechanism covers one of the two joints of the partial longitudinal waterstop 1 and the circumferential waterstop 2. Each set of connection mechanisms includes two connection plates 21, as well as a second connecting member and a second limiting member for locking the relative positions of the two connection plates 21. The connection plate 21 includes a first connection section 211 and a second connection section 212. The first connection sections 211 of the two connection plates 21 are arranged oppositely and are respectively located at the top and bottom of the longitudinal waterstop 1. A second cavity is provided on the surface of each first connection section 211 facing the longitudinal waterstop 1. The second cavities of the two first connection sections 211 face each other and enclose a second circumferential limiting cavity that fits the shape of at least a part of the longitudinal waterstop 1. The second connection sections 212 of the two connection plates 21 are arranged oppositely and are respectively located at the top and bottom of the joint close to the first connection section 211. A third cavity is provided on the surface of each second connection section 212 facing the joint. The third cavities of the two second connection sections 212 face each other and enclose a third circumferential limiting cavity that fits the shape of the joint.

[0039] The installation mechanism is used to install the longitudinal waterstop 1 in the construction joint. The connection mechanism is used to effectively connect the joints of the circumferential waterstop 2 and the longitudinal waterstop 1, and install them in the construction joint. The two mounting plates 11 of the installation mechanism respectively clamp the longitudinal waterstop 1 from the top and bottom. The contour of the cavity wall of the first circumferential limiting cavity matches the contour of the longitudinal waterstop 1, so that the two mounting plates 11 can be effectively limited with the longitudinal waterstop 1. Then, the positions of the two mounting plates 11 are limited by the first connecting piece and the first limiting piece, so that the two mounting plates 11 are tightly connected to the longitudinal waterstop 1. The first connecting sections 211 of the two connecting plates 21 of the connection mechanism respectively clamp the top and bottom of the longitudinal waterstop 1. The contour of the cavity wall of the second circumferential limiting cavity matches the contour of the partial longitudinal waterstop 1, so that the two first connecting sections 211 can be effectively limited with the partial longitudinal waterstop 1. Then, the positions of the two first connecting sections 211 are limited by the second connecting piece and the second limiting piece, so that the two first connecting sections 211 are tightly connected to the longitudinal waterstop 1. The circumferential waterstop 2 includes an upper circumferential belt and a lower circumferential belt, and the upper circumferential belt and the lower circumferential belt have two joints, which are respectively located on both sides of the longitudinal waterstop 1. The same connection mechanism covers the partial longitudinal waterstop and the joint on the same side as it, inserts the joint on this side into the second connecting sections 212 of the two connecting plates 21, and the end of the joint abuts against the end of the longitudinal waterstop 1. The two second connecting sections 212 respectively clamp the top and bottom of the joint. The contour of the cavity wall of the third circumferential limiting cavity matches the contour of the joint, so that the two second connecting sections 212 can be effectively limited with the joint. Then, the positions of the two second connecting sections 212 are limited by the second connecting piece and the second limiting piece, so that the two second connecting sections 212 are tightly connected to the joint. By adopting the above waterstop positioning and connecting device, the installation mechanism can reduce the installation difficulty of the longitudinal waterstop, and the connecting structure can reduce the connection difficulty and installation difficulty between the longitudinal waterstop 1 and the circumferential waterstop 2, so that the construction joint and the waterstop are tightly connected, eliminating the hidden danger of water leakage.

[0040] In this embodiment, waterstop ribs are provided on both side surfaces of the longitudinal waterstop 1 in the width direction. A plurality of (such as 4) waterstop ribs are spaced along the length direction of the longitudinal waterstop 1 and are symmetrically distributed along the center line of the longitudinal waterstop 1. Waterstop ends are respectively provided at opposite ends of the longitudinal waterstop 1, and the cross section of the waterstop end is a horizontally placed isosceles trapezoid. Two through holes are provided on the longitudinal waterstop 1, respectively close to the two waterstop ends, and each through hole is used for the first connecting member and the first limiting member to penetrate and connect. A first groove is provided on the surface of the mounting plate 11 facing the longitudinal waterstop 1. A plurality of first grooves are spaced along the length direction of the mounting plate 11 and are symmetrically distributed along the center line of the mounting plate 11. Each first groove is used to accommodate a waterstop rib. Inclined surfaces matching the inclined lines of the waterstop ends are provided on both end faces of the mounting plate 11. Two first connection holes are provided on the mounting plate 11, respectively close to the two inclined surfaces. The surface of each mounting plate 11 facing away from the longitudinal waterstop 1 is a flat surface. The mounting plate 11 at the bottom of the longitudinal waterstop 1 abuts against the end face of the inverted arch through the flat surface, and the mounting plate 11 at the top of the longitudinal waterstop 1 abuts against the end face of the circular arch through the flat surface.

[0041] In this embodiment, the circumferential waterstop 2 includes an upper circumferential belt and a lower circumferential belt. The upper circumferential belt and the lower circumferential belt have two joints, respectively located on the left and right sides of the longitudinal waterstop 1 (such as Figure 4As shown in the figure, the first connecting section 211 on the left side can clamp and limit half of the longitudinal waterstop, and the first connecting section 211 on the right side can clamp and limit the other half of the longitudinal waterstop. Each half of the longitudinal waterstop includes waterstop ribs arranged oppositely on both side surfaces along the width direction, multiple (such as 2) waterstop ribs are spaced along the length direction of the longitudinal waterstop 1, and a waterstop end at the end. A through hole is also arranged between two waterstop ribs, and the through hole is used for the second connecting piece and the second limiting piece to pass through and connect. The left connecting mechanism and the right connecting mechanism are symmetrically distributed in a mirror image along the midline of the longitudinal waterstop 1. Taking the left connecting mechanism as an example, the surface of the first connecting section 211 facing the longitudinal waterstop 1 is provided with second grooves, and multiple second grooves are spaced along the length direction of the first connecting section 211. Each second groove is used to accommodate a waterstop rib; a limiting groove for accommodating the local waterstop end is also arranged on the first connecting section 211, and the cross section of the limiting groove is a right triangle; a second connecting hole is arranged between two second grooves of the first connecting section 211. The surface of the first connecting section 211 facing away from the longitudinal waterstop 1 is a flat surface. The first connecting section 211 at the bottom of the longitudinal waterstop 1 abuts against the invert end face through the flat surface, and the first connecting section 211 at the top of the longitudinal waterstop 1 abuts against the arch ring end face through the flat surface. The joint between the upper circumferential belt and the lower circumferential belt is straight, so the surface of the second connecting section 212 facing the joint is a flat surface, and a second connecting hole is arranged on the second connecting section 212 near the free end. The surface of the second connecting section 212 facing away from the joint is a flat surface. The second connecting section 212 at the bottom of the joint abuts against the invert end face through the flat surface, and the second connecting section 212 at the top of the joint abuts against the arch ring end face through the flat surface. Since the height of the joint is basically the same as the height of the belt body of the longitudinal waterstop, the surface of the second connecting section 212 facing the joint is flush with the surface of the first connecting section 211 facing the longitudinal waterstop 1.

[0042] In this embodiment, the first connecting piece and the first limiting piece include a first connecting piece 12 and a first limiting piece 13. A first connecting hole (not marked) is arranged on each mounting plate 11; the first connecting piece 12 can pass through the first connecting holes arranged oppositely on two mounting plates 11 and the longitudinal waterstop 1; the first limiting piece 13 can be connected to the first connecting piece 12 and is used to cooperate with the first connecting piece 12 to limit the distance between two mounting plates 11. When the longitudinal waterstop 1 is placed in the first circumferential limiting cavity formed by enclosing two mounting plates 11, the first connecting piece 12 passes through from top to bottom in sequence, and then the first limiting piece 13 is connected to the first connecting piece 12. The two cooperate to adjust the distance between two mounting plates 11, so that the mounting plates 11 can squeeze the longitudinal waterstop 1 to form a tight connection.

[0043] In this embodiment, the first connection hole includes, but is not limited to, a countersunk hole. When the first connecting member 12 and the first limiting member 13 can be respectively installed in the countersunk holes of the two mounting plates 11, it can be avoided from protruding out of the surface of the mounting plate 11, so as to seal the construction joint.

[0044] In this embodiment, the first connecting member 12 and the first limiting member 13 are connected by threads. Threaded connection is a kind of detachable connection method, which is convenient for disassembly and assembly, and has good connection stability at the same time; moreover, the threaded connection can improve the adjustment accuracy and accurately adjust the external force intensity applied to the mounting plate 11.

[0045] In this embodiment, the first connecting member 12 includes, but is not limited to, a screw rod, and the first limiting member 13 includes, but is not limited to, a nut.

[0046] Preferably, the installation mechanism further includes: a first gasket 14. The first gasket 14 is arranged on the surface of the mounting plate 11 facing away from the longitudinal waterstop 1, and a first through hole (not marked) for installing the first connecting member 12 is arranged on the first gasket 14. By providing the first gasket 14, the sealing performance of the first connection hole of the mounting plate 11 can be enhanced, and the waterproof performance can be further improved.

[0047] In this embodiment, the first gasket 14 is made of a metal material to improve wear resistance and extend the service life.

[0048] The number of the first gaskets 14 is the same as the number of the first connecting member and the first limiting member, and is set according to the number of the first connection holes on the mounting plate 11. In this embodiment, the number of the first connection holes is four and is arranged in a 2×2 array on the mounting plate 11.

[0049] Preferably, a first sealant layer (not shown) is arranged on the surface of the mounting plate 11 facing the longitudinal waterstop 1. By providing the first sealant layer, the connection strength between the mounting plate 11 and the longitudinal waterstop 1 can be improved, and the waterproof property of the installation mechanism can also be improved, further achieving the purpose of waterproofing.

[0050] In this embodiment, the second connecting member and the second limiting member include a second connecting member 22 and a second limiting member 23. Second connection holes (not labeled) are provided on both the first connection section 211 and the second connection section 212 of each connecting plate 21. The number of the second connecting members and the second limiting members is multiple. At least one second connecting member 22 can penetrate through the relatively arranged second connection holes of the two first connection sections 211 and the longitudinal waterstop 1. At least one second connecting member 22 can penetrate through the relatively arranged second connection holes of the two second connection sections 212 and the joint. The second limiting member 23 can be connected to the second connecting member 22 and is used to cooperate with the second connecting member 22 to limit the distance between the two connecting plates 21. When the longitudinal waterstop 1 is placed in the second circumferential limiting cavity formed by the enclosure of the two connecting plates 21, the second connecting member 22 penetrates from top to bottom in sequence, and then the second limiting member 23 is connected to the second connecting member 22. The two cooperate with each other to adjust the distance between the two connecting plates 21, so that the connecting plates 21 can squeeze the longitudinal waterstop 1 to form a tight connection. When the joint of the circumferential waterstop 2 is placed in the third circumferential limiting cavity formed by the enclosure of the two connecting plates 21, the second connecting member 22 penetrates from top to bottom in sequence, and then the second limiting member 23 is connected to the second connecting member 22. The two cooperate with each other to adjust the distance between the two connecting plates 21, so that the connecting plates 21 can squeeze the joint of the circumferential waterstop 2 to form a tight connection.

[0051] In this embodiment, the second connection hole includes but is not limited to a countersunk hole. When the second connecting member 22 and the second limiting member 23 can be respectively installed in the countersunk holes of the two connecting plates 21, it can be avoided from protruding from the surface of the connecting plates 21, so as to seal the construction joint.

[0052] In this embodiment, the second connecting member 22 and the second limiting member 23 are connected by threads. Thread connection is one of the detachable connection methods, which is convenient for disassembly and assembly, and has good connection stability at the same time. Moreover, thread connection can improve the adjustment accuracy and accurately adjust the external force intensity applied to the connecting plate 21.

[0053] In this embodiment, the second connecting member 22 includes but is not limited to a screw rod, and the second limiting member 23 includes but is not limited to a nut.

[0054] Second gaskets 24. The number of the second gaskets 24 is multiple. At least one second gasket 24 is arranged on the surface of the first connection section 211 of the connecting plate 21 on the side facing away from the longitudinal waterstop 1. At least one second gasket 24 is arranged on the surface of the second connection section 212 of the connecting plate 21 on the side facing away from the joint. Second through holes (not labeled) for installing the second connecting member 22 are provided on the second gaskets 24. By arranging the second gaskets 24, the sealing performance of the second connection holes of the connecting plates 21 can be enhanced, and the waterproof performance can be further improved.

[0055] In this embodiment, the second gasket 24 is made of a metal material, which improves wear resistance and extends the service life.

[0056] The number of the second gaskets 24 is the same as the number of the second limiting connectors, and both are set according to the number of the second connection holes on the connection plate 21. In this embodiment, the number of the second connection holes is four, which are arranged in two on the first connection section 211 and the second connection section 212 respectively. Among them, two second connection holes are arranged at intervals along the width direction of the first connection section 211 and are arranged close to the free end of the first connection section 211, and the other two second connection holes are arranged at intervals along the width direction of the second connection section 212 and are arranged close to the free end of the second connection section 212.

[0057] In addition, preferably, a second sealant layer (not shown) is provided on the surface of the first connection section 211 of the connection plate 21 facing the longitudinal waterstop 1, and a third sealant layer (not shown) is provided on the surface of the second connection section 212 of the connection plate 21 facing the connection part. By providing the second sealant layer, the connection strength between the longitudinal waterstop 1 and the second connection section 212 can be improved. By providing the third sealant layer, the connection strength between the connection part of the circumferential waterstop 2 and the second connection section 212 can be improved. By providing the second sealant layer and the third sealant layer, the waterproof property of the connection mechanism can also be improved, further achieving the purpose of waterproofing.

[0058] In this embodiment, the mounting plate 11 and / or the connection plate 21 are made of a rubber material. The rubber material is elastic and deforms under an external force, which helps to achieve a tight connection. Moreover, the rubber material has the advantages of water isolation, wear resistance, and long service life. When the longitudinal waterstop 1 is installed between two oppositely arranged mounting plates 11, the first connecting piece and the first limiting piece provide an external force for the mounting plate 11, and deformation occurs between the longitudinal waterstop 1 and the mounting plate 11, so that a tight connection can be formed. Similarly, when the longitudinal waterstop 1 and the circumferential waterstop 2 are in contact with each other and are located between two connection plates 21, the second limiting connector provides an external force for the connection plate 21, and deformation occurs between the longitudinal waterstop 1 and the first connection section 211, so that a tight connection can be formed; deformation occurs between the connection part and the second connection section 212, so that a tight connection can be formed.

[0059] In this embodiment, both the longitudinal waterstop 1 and the circumferential waterstop 2 are made of a rubber material, and both the mounting plate 11 and the connection plate 21 are made of a rubber material.

[0060] The following further introduces the using process of the waterstop positioning and connecting device.

[0061] A first sealant layer is provided on the surface of the mounting plate 11 facing the longitudinal waterstop 1. The two mounting plates 11 are respectively clamped from the top and bottom of the longitudinal waterstop 1. Each waterstop rib is inserted into the corresponding first groove, and the inclined surface abuts against the waterstop end. Then, the longitudinal waterstop 1 is placed in the first circumferential limiting cavity. A first gasket 14 is installed on the side of the two mounting plates 11 facing away from the longitudinal waterstop 1. The first connecting member 12 sequentially passes through the first connection holes of the mounting plate 11 at the top, the through holes of the longitudinal waterstop 1, and the first connection holes of the mounting plate 11 at the bottom.

[0065] (1) Place the installation mechanism on the invert end face. The installation mechanism includes two mounting plates 11, a first connecting member, and a first limiting member. Set the first cavities of the two mounting plates 11 opposite to each other, and respectively located at the top and bottom of the longitudinal waterstop 1. Place the longitudinal waterstop 1 in the first circumferential limiting cavity formed by the two mounting plates 11, and use the first connecting member and the first limiting member to lock the relative positions of the two mounting plates 11;

[0066] (2) Set two groups of connecting mechanisms on the opposite sides of the longitudinal waterstop 1 respectively. Each connecting mechanism covers one of the two joints of the partial longitudinal waterstop 1 and the circumferential waterstop 2. The connecting mechanism includes two connecting plates 21, a second connecting member, and a second limiting member;

[0068] (4) Repeat step (3) to install the other group of connecting mechanisms.

[0069] The installation mechanism is used to install the longitudinal waterstop 1 in the construction joint. The connection mechanism is used to effectively connect the joints of the circumferential waterstop 2 and the longitudinal waterstop 1, and to install them in the construction joint. The two mounting plates 11 of the installation mechanism respectively clamp the longitudinal waterstop 1 from the top and bottom. The contour of the cavity wall of the first circumferential limiting cavity coincides with the contour of the longitudinal waterstop 1, so that the two mounting plates 11 can be effectively limited with the longitudinal waterstop 1. Then, the positions of the two mounting plates 11 are limited by the first connecting piece and the first limiting piece, so that the two mounting plates 11 are tightly connected to the longitudinal waterstop 1. The first connecting segments 211 of the two connecting plates 21 of the connection mechanism respectively clamp the top and bottom of the longitudinal waterstop 1. The contour of the cavity wall of the second circumferential limiting cavity coincides with the contour of the partial longitudinal waterstop 1, so that the two first connecting segments 211 can be effectively limited with the partial longitudinal waterstop 1. Then, the positions of the two first connecting segments 211 are limited by the second connecting piece and the second limiting piece, so that the two first connecting segments 211 are tightly connected to the longitudinal waterstop 1. The circumferential waterstop 2 includes an upper circumferential belt and a lower circumferential belt, and the upper circumferential belt and the lower circumferential belt have two joints, which are respectively located on both sides of the longitudinal waterstop 1. The same connection mechanism covers the partial longitudinal waterstop 1 and the joint on the same side as it, inserts the joint on this side into the second connecting segments 212 of the two connecting plates 21, and the end of the joint abuts against the end of the longitudinal waterstop 1. The two second connecting segments 212 respectively clamp the top and bottom of the joint. The contour of the cavity wall of the third circumferential limiting cavity coincides with the contour of the joint, so that the two second connecting segments 212 can be effectively limited with the joint. Then, the positions of the two second connecting segments 212 are limited by the second connecting piece and the second limiting piece, so that the two second connecting segments 212 are tightly connected to the joint. By adopting the construction method of the above waterstop positioning and connecting device, the installation mechanism can reduce the installation difficulty of the longitudinal waterstop 1, and the connection structure can reduce the connection difficulty and installation difficulty of the longitudinal waterstop 1 and the circumferential waterstop 2, so that the construction joint and the waterstop are tightly connected, eliminating the hidden danger of water leakage.

The second limiting member 23 can be connected to the second connecting member 22 and is used to cooperate with the second connecting member 22 to limit the distance between the two connection plates 21. When the longitudinal water stop 1 is placed in the second circumferential limiting cavity formed by the enclosure of the two connection plates 21, the second connecting member 22 penetrates from top to bottom in sequence, and then the second limiting member 23 is connected to the second connecting member 22. The two cooperate with each other to adjust the distance between the two connection plates 21, so that the connection plates 21 can squeeze the longitudinal water stop 1 to form a tight connection. When the joint of the circumferential water stop 2 is placed in the third circumferential limiting cavity formed by the enclosure of the two connection plates 21, the second connecting member 22 penetrates from top to bottom in sequence, and then the second limiting member 23 is connected to the second connecting member 22.
