Water shutoff device

Abstract

This invention provides a water-stopping device, relating to the field of building waterproofing technology. The water-stopping device includes a water-stopping steel plate and a drain pipe arranged along the length of the water-stopping steel plate. The drain pipe has a drain outlet along its length, allowing groundwater that has seeped onto the upper surface of the water-stopping steel plate to flow into the drain outlet. By installing this water-stopping device, the water-stopping steel plate can be used to seal the interface joint between pre- and post-cast concrete. If the water-stopping steel plate fails to stop the water flow, and the seeping groundwater flows from the interface joint between the water-stopping steel plate and the concrete to the upper surface of the water-stopping steel plate, the seeping groundwater will flow into the drain pipe through the drain outlet and then into a nearby sump. This prevents groundwater seeping through the concrete interface joint from leaking onto the basement floor surface, making the water-stopping device an integrated blocking and draining system with multiple lines of water-stopping defense, significantly improving the water-stopping effect at the post-cast concrete joint.

Description

Technical Field

[0001] This invention relates to the field of waterproofing technology in building construction, and more specifically, to a water-stopping device. Background Technology

[0002] Water-stopping devices are mainly used in foundation engineering when concrete is cast in place, placed in construction joints and expansion joints to become an integral part of the concrete structure.

[0003] Currently, during basement construction, the steel waterstops attached to the post-cast strips of the basement floor slab are typically made of galvanized steel plates and are installed on the basement floor slab during concrete pouring. However, due to concrete shrinkage after pouring, an interface joint usually forms at the junction of the steel waterstop and the concrete. If there are defects in the subbase or waterproofing layer, groundwater can seep into the bottom surface of the basement structural members through these defects and then leak upwards through the defects at the post-cast strip interface. Upon encountering the waterstop steel plate, it will continue to leak upwards along the interface joint between the waterstop steel plate and the concrete or along any defects.

[0004] To address the inherent defects of steel plate waterstops, existing methods use water-swellable rubber waterstops instead of steel plate waterstops at the post-cast joints of basement slabs. These are also installed in the middle of the basement slab before the first concrete pour. However, during the first concrete pour, the water-swellable rubber waterstop absorbs moisture from the concrete before initial setting, easily leading to defects at the interface between the waterstop and the concrete. While the expansion of the rubber waterstop upon contact with water can fill some of these interface defects, it cannot guarantee that all defects will be filled. Furthermore, during later stages of the building's use, factors such as rising groundwater levels may cause repeated micro-deformations in the basement slab, potentially widening defects or interface joints at the waterstop's interface with the concrete, further affecting the waterstop's sealing effect.

[0005] Therefore, providing a new water-stopping device has become an urgent technical problem to be solved. Summary of the Invention

[0006] The present invention aims to provide, for example, a water-stopping device that can simultaneously stop water flow and drain water, thereby improving the situation where groundwater seeps through the interface joints of the post-cast strip of the base slab to the upper surface of the base slab, thus affecting the normal use of the basement.

The gap in the height direction of the overlapping part of the first component and the second component forms the drain outlet.

[0021] In an optional embodiment, a water inlet is provided in the area where the second component overlaps with the first component; and / or,

[0022] A deposition groove is formed by a downward recess in the middle of the area where the first component and the second component overlap in the width direction; and / or,

[0023] The water-stopping device also includes geotextile, which is disposed on the outside of the first component and the second component.

[0024] In an optional embodiment, the drain pipe includes a pipe body and a cover plate.

[0025] The pipe body has an M-shaped structure and is welded to the top of the water-stop steel plate. The top wall of the pipe body is provided with a flow hole.

[0027] In an optional embodiment, the pipe body includes a first connecting plate, a second connecting plate, a third connecting plate, a fourth connecting plate, a fifth connecting plate, a sixth connecting plate, and a seventh connecting plate connected sequentially. The first connecting plate and the seventh connecting plate are arranged opposite each other, and their bottom ends are both inclined outwards and connected to the water-stop steel plate. The second connecting plate and the sixth connecting plate are both horizontally arranged. The side of the third connecting plate away from the second connecting plate extends downwards at an incline. The side of the fifth connecting plate away from the sixth connecting plate also extends downwards at an incline. The fourth connecting plate is horizontally arranged and is lower than the second connecting plate and the sixth connecting plate.

[0053] Example

[0054] Please refer to Figures 1 to 7 This embodiment provides a water-stopping device 100, which integrates blocking and drainage to significantly improve the water-stopping effect.

[0055] In this embodiment, the water-stopping device 100 includes a water-stopping steel plate 110 and a drain pipe 130 arranged along the length of the water-stopping steel plate 110. The drain pipe 130 is provided with a drain outlet 131 along the length, and water on the upper surface of the water-stopping steel plate 110 can flow into the drain outlet 131.

[0056] In this embodiment, by setting a water-stop steel plate 110, the joint can be sealed using the water-stop steel plate 110. If water flows into the upper surface of the water-stop steel plate 110 from the interface between the water-stop steel plate 110 and the concrete, the water will flow into the drain pipe 130 through the drain outlet 131 and then into the water collection pit. This can prevent water from seeping into the surface from the joint, so that the water-stopping device 100 forms a blockage and drainage system, forming multiple lines of defense and significantly improving the water-stopping effect.

[0057] Example 1

[0058] Please refer to Figure 1 and Figure 2 In this embodiment, the water-stop steel plate 110 includes a first water-stop steel plate 111 and a second water-stop steel plate 113. The first water-stop steel plate 111 and the second water-stop steel plate 113 are connected to both sides of the drain pipe 130, and the drain pipe 130 is located below the first water-stop steel plate 111 and the second water-stop steel plate 113. One of the first water-stop steel plate 111 and the second water-stop steel plate 113 extends over the other to form a shield above the drain outlet 131, and forms a flow gap 115 at intervals in the height direction. The flow gap 115 communicates with the drain outlet 131.

[0059] In this embodiment, the drain pipe 130 is positioned below the first water-stop steel plate 111 and the second water-stop steel plate 113, and one of the first water-stop steel plate 111 and the second water-stop steel plate 113 extends over the other to form a shield above the drain outlet 131. In this way, water will flow into the drain outlet 131 from the end face of the flow gap 115 and then be discharged into the water collection pit. The first water-stop steel plate 111 and the second water-stop steel plate 113 can form a shield above the drain outlet 131 and support the concrete, thereby preventing the slurry in the concrete from flowing into the drain outlet 131 during the pouring process and shielding the drain outlet 131.

[0060] Please refer to Figure 1 and Figure 2 In this embodiment, the drain pipe 130 includes a superior arc pipe section 133 and a inferior arc pipe section 135. The superior arc pipe section 133 is connected to the lower side of one side of the first water-stop steel plate 111 in the width direction and extends along the length direction of the first water-stop steel plate 111. The inferior arc pipe section 135 is connected to the lower side of one side of the second water-stop steel plate 113 in the width direction and extends along the length direction of the second water-stop steel plate 113. The superior arc pipe section 133 and the inferior arc pipe section 135 are detachably connected by fasteners.

[0061] This two-part configuration allows the first water-stop steel plate 111 to be pre-embedded during the initial pouring of the first section, and the second water-stop steel plate 113 to be installed during the subsequent pouring of the second section before concrete is poured. This also makes it easier to clean the inside of the drain pipe 130 after the first concrete pouring is completed.

[0062] Please refer to Figure 1 In this embodiment, the water-stopping device 100 also includes a spacing adjustment component. The first water-stopping steel plate 111 and the second water-stopping steel plate 113 are connected by the spacing adjustment component, which can adjust the gap size between the first water-stopping steel plate 111 and the second water-stopping steel plate 113.

[0063] Generally, the spacing adjustment component can be a bolt, a washer, etc., which can maintain a preset gap between the first waterstop steel plate 111 and the second waterstop steel plate 113 to prevent them from being squeezed by concrete and thus not fitting together.

[0064] Please refer to Figure 1 and Figure 2 In this embodiment, the water-stopping device 100 further includes a filter cloth 161, which is disposed between the first water-stopping steel plate 111 and the second water-stopping steel plate 113.

[0065] Laying a filter cloth can cover the opening of the flow gap to prevent particles from entering the flow gap 115 during pouring, and the filter cloth is permeable to water so that water can flow from the flow gap 115 into the drain pipe 130.

[0066] In this embodiment, the first water-stop steel plate 111 and the second water-stop steel plate 113 are 3mm galvanized steel plates or stainless steel plates.

[0067] In this embodiment, the bottom (back) surfaces of the first water-stop steel plate 111 and the second water-stop steel plate 113 are covered with water-swellable rubber 190. The water-swellable rubber 190 expands when exposed to water, thereby sealing the interface gaps and improving the water-stopping effect.

[0068] Example 2

[0069] Please refer to Figure 3 In this embodiment, the water-stop steel plate 110 is a single plate. The drain pipe 130 includes a first component 137 and a second component 139. The first component 137 and the second component 139 are spaced apart in the middle of the water-stop steel plate 110, and one side in the width direction is welded to the top of the water-stop steel plate 110. The other side in the width direction of the first component 137 bends and extends toward the second component 139, and the other side in the width direction of the second component 139 bends and extends toward the first component 137 to above the first component 137, and partially overlaps with the first component 137, forming a trapezoidal structure above the water-stop steel plate 110. The overlap of the first component 137 and the second component 139 forms a drain outlet 131 in the height direction.

[0070] In this embodiment, the drain pipe 130 formed by the first component 137 and the second component 139 is located above the water-stop steel plate 110. The other side of the second component 139 in the width direction bends and extends towards the first component 137 to the top of the first component 137 and partially overlaps with the first component 137. This ensures that the formed drain outlet 131 is located on the side and will not be blocked by concrete, and concrete will not enter the interior of the drain pipe 130 and block the drain pipe 130.

[0071] Please refer to Figure 3 In this embodiment, a water inlet 141 is provided in the area where the second component 139 overlaps with the first component 137. The water inlet 141 can be blocked vertically by the first component 137 below, thereby preventing concrete from flowing into the drain pipe 130.

[0072] In this embodiment, the water-stopping device 100 further includes a geotextile 166, which is disposed on the outside of the first component 137 and the second component 139.

[0073] Covering with geotextile 166 can prevent concrete particles from entering the overlapping area between the second component 139 and the first component, thereby preventing the drain outlet 131 from being blocked.

[0074] In this embodiment, a deposition groove 143 is formed by a downward recess in the middle of the area where the first component 137 and the second component 139 overlap in the width direction.

[0075] During concrete pouring, water in the concrete carries cement and other materials through the geotextile 166 into the gaps and deposits within them. Drying can then block the drain outlet 131. In this embodiment, a sedimentation tank 143 is provided so that cement particles entering the gaps can be deposited in the sedimentation tank 143, thereby avoiding blockage of the area at the end of the first component 137.

[0076] Please refer to Figure 3 In this embodiment, the two side walls of the sedimentation tank 143 are inclined trapezoids, which facilitates the deposition of cement in the sedimentation tank 143 after water and cement particles flow into the sedimentation tank 143.

[0077] In this embodiment, the water-stop steel plate 110 is a single piece, which is a galvanized steel plate or a stainless steel plate.

[0078] Secondly, regarding the water-stopping device 100 provided in the above two embodiments, this embodiment also provides a construction method for the water-stopping device 100, the method including:

[0079] Pour the concrete of the first section and install the water-stop device 100 at the joint, with the width portion of the water-stop device 100 being poured into the concrete layer of the first section;

[0080] A water collection pipe is connected to the end of the drain pipe 130 so that the drain pipe 130 is connected to the water collection pit.

[0081] After pouring the post-cast strip concrete layer, other water-stopping devices 100 are poured into the post-cast strip concrete layer.

[0082] This allows for both water blocking and better drainage.

[0083] Example 3

[0084] Please refer to Figures 4 to 6 In this embodiment, the water-stop steel plate 110 is a single plate. The drain pipe 130 includes a pipe body 145 and a cover plate 147. The pipe body 145 has an M-shaped structure and is welded to the top of the water-stop steel plate 110. The top wall of the pipe body 145 is provided with a flow hole 149. The cover plate 147 covers the top of the pipe body 145, and drain outlets 131 are respectively provided between the two sides of the cover plate 147 and the two sides of the pipe body 145 at intervals.

[0085] When using this water-stopping device 100 to stop water, the steel water-stopping plate 110 can block the joint. When water seeps to the top of the water-stopping plate 110, the water will flow in through the drain port 131, pass through the flow hole 149 and flow into the pipe formed by the pipe body 145 and the water-stopping plate 110, and then be discharged into the sump through the pipe to achieve drainage.

[0086] In this embodiment, the pipe body 145 includes a first connecting plate 151, a second connecting plate 152, a third connecting plate 153, a fourth connecting plate 154, a fifth connecting plate 155, a sixth connecting plate 156, and a seventh connecting plate 157 connected sequentially. The first connecting plate 151 and the seventh connecting plate 157 are arranged opposite each other, and their bottom ends are both inclined outwards and connected to the water-stop steel plate 110. The second connecting plate 152 and the sixth connecting plate 156 are both arranged horizontally. The side of the third connecting plate 153 away from the second connecting plate 152 extends downwards at an angle, and the side of the fifth connecting plate 155 away from the second connecting plate 152 extends downwards at an angle. The sixth connecting plate 156 extends downward at an angle on one side, and the fourth connecting plate 154 is set horizontally and is lower than the second connecting plate 152 and the sixth connecting plate 156; the third connecting plate 153, the fourth connecting plate 154 and the fifth connecting plate 155 form a U-shaped blocking groove, and each of the third connecting plate 153, the fourth connecting plate 154 and the fifth connecting plate 155 is provided with a flow hole 149; the cover plate 147 is set above the second connecting plate 152 and the sixth connecting plate 156, and a drain outlet 131 is formed between the second connecting plate 152 and the sixth connecting plate 156;

[0087] A pipe body 145, consisting of a first connecting plate 151, a second connecting plate 152, a third connecting plate 153, a fourth connecting plate 154, a fifth connecting plate 155, a sixth connecting plate 156, and a seventh connecting plate 157 connected in sequence, is formed, resulting in high structural strength. When used in conjunction with a cover plate 147, it can block the top of the flow hole 149, thus providing support for the concrete. The drainage outlets formed between the cover plate 147 and the second connecting plate 152, and between the cover plate 147 and the sixth connecting plate 156, allow water to flow in. In this embodiment, to prevent blockage of the drain outlet 131 formed at the bottom of the cover plate 147, the water-stopping device 100 also includes an elastic element 171 and a connecting element 173. The second connecting plate 152 and the cover plate 147, as well as the sixth connecting plate 156 and the cover plate 147, are connected by connectors 173. Elastic members 171 are provided between the second connecting plate 152 and the cover plate 147, and between the sixth connecting plate 156 and the cover plate 147, allowing the second connecting plate 152 and the cover plate 147, and the sixth connecting plate 156 and the cover plate 147, to be spaced apart and floatingly connected. The water-stopping device 100 also includes a stop cloth 165, which covers the outside of the cover plate 147, the first connecting plate 151, and the seventh connecting plate 157.

[0088] The baffle cloth 165 can block particulate matter to prevent it from clogging the drain outlet 131. The elastic element 171 also ensures the unobstructed flow of the drain outlet 131. Specifically, during the pouring process, when the vibrating equipment applies vibration force to the cover plate 147, the cover plate 147 can float relative to the water-stop steel plate 110, allowing stones or deposited cement slurry stuck in the drain outlet 131 to flow away, thus ensuring unobstructed flow. Secondly, it is simple to manufacture; it can be produced through bending and punching, resulting in low cost.

[0089] Please refer to Figures 4 to 6 In this embodiment, the connector 173 is a bolt, and the elastic element 171 is a spring. The bolt connects the second connecting plate 152 and the cover plate 147, and the spring is sleeved on the bolt, with its top abutting against the cover plate 147 and its bottom abutting against the steel waterstop plate 110. In this way, the spring can achieve a floating connection of the cover plate 147, or it can separate the cover plate 147 to form a gap. Furthermore, this makes the steel waterstop plate 110 a single unit, which is more conducive to water blocking.

[0090] Example 4

[0091] Please refer to Figure 7 The water-stopping device 100 also includes multiple baffles 159. The water-stopping steel plate 110 is bent and recessed in the middle of its width direction to form a drain pipe 130. The multiple baffles 159 are sequentially and partially stacked in the width direction, with a drain outlet 131 spaced apart between adjacent stacked baffles 159. Two baffles 159 located on either side are respectively connected to the water-stopping steel plate 110.

[0092] This type of water-stop steel plate 110 is integrally formed, resulting in better water-blocking effect. It also facilitates drainage.

[0093] Specifically, the recessed drain pipe 130 has a U-shaped structure. Of course, in other embodiments of this application, it can also be V-shaped. There are three baffles 159, which are partially stacked sequentially in the width direction. A pad is provided between the stacked portions of two adjacent baffles 159 to create a gap in height between the two baffles, which serves as a drain outlet 131.

[0094] The first baffle 159 and the third baffle 159 are connected to the upper surface of the waterstop steel plate 110 and are spaced apart from the waterstop steel plate 110.

[0095] Furthermore, to prevent cement mortar from blocking the drain outlet 131, geotextile 166 can be laid on the upper surface of the waterstop steel plate 110, which can prevent cement mortar from entering the gap.

[0096] In summary, the working materials and beneficial effects of the water-stopping device 100 provided in this embodiment of the invention include:

[0097] In this embodiment, by setting a water-stop steel plate 110, the joint can be sealed using the water-stop steel plate 110. If water flows into the upper surface of the water-stop steel plate 110 from the interface between the water-stop steel plate 110 and the concrete, the water will flow into the drain pipe 130 through the drain outlet 131 and then into the water collection pit. This can prevent water from seeping into the surface from the joint, so that the water-stopping device 100 forms a blockage and drainage system, forming multiple lines of defense and significantly improving the water-stopping effect.

[0098] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
