Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a modular water-retaining edge and a water-retaining system for foundation construction. Background Technology

[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] During the rainy season, the installation of water-retaining edges is indeed a key waterproofing measure during the foundation construction phase of a building project. Their function is to prevent surface water from seeping into the foundation pit, thus preventing soil soaking that could lead to slope instability or a decrease in the bearing capacity of the foundation. Water-retaining edges can form a continuous waterproof barrier around the top of the foundation pit, intercepting rainwater from flowing directly into it. They can also be integrated with drainage systems to guide surface water systematically to collection wells or municipal pipe networks. Furthermore, water-retaining edges can reduce the lateral pressure of rainwater on the support structure, lowering the risk of landslides.

[0004] However, the inventors discovered that some projects have many foundations, large spans between adjacent foundations, and short construction periods for individual foundations. After the foundation backfilling is completed, the water-retaining edge is basically unusable. In this case, setting up a formal water-retaining edge is costly and consumes a lot of manpower and resources. Temporary water-retaining cofferdams are ineffective, unsightly, and easily eroded by flowing water. Therefore, a modular water-retaining edge that is easy to set up and reusable is needed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a modular water-retaining edge and foundation construction water-retaining system that is reusable, easy to assemble and disassemble, and plug-and-play. It is not only aesthetically pleasing but also greatly improves the construction efficiency of foundation construction water-retaining systems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Firstly, this utility model provides a modular water-blocking edge.

[0008] A modular water-blocking edge includes: a water-blocking edge body that is rectangular in shape, the water-blocking edge body including a uniform thickness region and a gradually tapering thickness region that are both rectangular, the gradually tapering thickness region being located at the bottom of the uniform thickness region and integrally formed;

[0009] A metal rod is connected to the bottom of the uniform thickness zone. The metal rod passes through the uniform thickness zone and is fixedly connected to the uniform thickness zone. A tenon is provided on one side of the uniform thickness zone and a mortise is provided on the other side of the uniform thickness zone. The tenon and the mortise are respectively used to connect with the adjacent modular water-blocking edge.

[0010] As a further definition of the first aspect of this utility model, the thickness of the uniform thickness region is D1, and the thickness of the gradually tapering thickness region gradually decreases from D1 to D2.

[0011] As a further limitation of the first aspect of this utility model, the thickness D1 of the uniform thickness region is 10mm, and the thickness of the gradually tapering thickness region gradually decreases from 10mm to 2mm.

[0014] As a further limitation of the first aspect of this utility model, the metal rod is a steel rod, and the length of the steel rod is 300mm.

[0015] As a further limitation of the first aspect of this utility model, the steel rod passes through the tapering thickness region and is welded and fixedly connected to the tapering thickness region.

[0016] As a further definition of the first aspect of this utility model, the tenon protrudes from one side of the uniform thickness region, and the mortise is a groove that mates with the tenon, the groove being located on the other side of the uniform thickness region.

[0017] Secondly, this utility model provides a basic construction water-retaining system.

[0018] A basic construction water-retaining system includes multiple modular water-retaining edges as described in the first aspect of this utility model. Each modular water-retaining edge is connected sequentially by tenons and mortises to form a rectangular water-retaining system.

[0019] The right-angle section of the rectangular water-blocking system uses a 90° connecting plate to connect two adjacent modular water-blocking edges. The two sides of the 90° connecting plate are provided with mortises and tenons respectively.

[0020] As a further limitation of the second aspect of this utility model, a metal rod is connected to the bottom of the 90° connecting plate.

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0031] It should be noted that the following detailed description is exemplary and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0032] Where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0033] Example 1:

[0034] As described in the background section, traditional brick-built water-retaining edges cannot be reused, and their installation consumes too much manpower and resources. Temporary water-retaining dikes are ineffective, unsightly, and easily eroded by flowing water. Therefore, this implementation proposes a modular water-retaining edge, such as... Figure 1 and Figure 2 As shown, it includes: a water-blocking edge body that is rectangular in shape, the water-blocking edge body including a uniform thickness area and a gradually tapering thickness area that are both rectangular, the gradually tapering thickness area being located at the bottom of the uniform thickness area and being integrally formed;

[0035] A metal rod is connected to the bottom of the uniform thickness zone. The metal rod passes through the uniform thickness zone and is fixedly connected to the uniform thickness zone. A tenon is provided on one side of the uniform thickness zone and a mortise is provided on the other side of the uniform thickness zone. The tenon and the mortise are respectively used to connect with the adjacent modular water-blocking edge.

[0036] In this implementation, preferably, the thickness D1 of the uniform thickness region is 10mm, the thickness of the gradually tapering thickness region gradually decreases from 10mm to 2mm (i.e., D2), the length of the uniform thickness region is 1000mm, the height of the uniform thickness region is 300mm, and the height of the gradually tapering thickness region is 50mm.

[0037] Understandably, the thicknesses mentioned here are all schematic designs, i.e. preferred choices, not specific limitations. Those skilled in the art can modify them according to the specific usage environment. For example, the thickness of the uniform thickness zone can also be 15mm or 20mm, etc. The thickness of the tapering thickness zone needs to be tapered based on the thickness of the uniform thickness zone to ensure continuity. The length and height of the uniform thickness zone and the height of the tapering thickness zone can be selected according to the specific situation, which will not be elaborated here.

[0038] In this implementation, preferably, the metal rod is a steel rod with a length of 300mm. It is understood that the length of the steel rod can also be selected according to the specific working conditions. For example, 250mm or 350mm can be selected, etc. Those skilled in the art can select according to the specific working conditions, which will not be elaborated here.

[0039] In this implementation, preferably, the steel rod passes through the tapering thickness region and is welded and fixedly connected to the tapering thickness region. The welding and fixing method can ensure the strength when inserted into the soil. It is understood that in some other implementations, the steel rod can also be integrally formed with the tapering thickness region and the uniform thickness region, which will not be elaborated here.

[0040] In this implementation, preferably, the tenon protrudes from one side of the uniform thickness region, and the mortise is a groove that mates with the tenon, located on the other side of the uniform thickness region.

[0041] Traditional water-retaining edge construction costs approximately 400 yuan per linear meter (taking 30cm high as an example) (including labor and materials). Moreover, the water-retaining edge cannot be reused after the foundation pit construction is completed and can only be scrapped, resulting in a lot of waste. Modular water-retaining edge, including labor and materials, costs approximately 120 yuan per linear meter. It is reusable, easy to disassemble and assemble, and can be used immediately.

[0042] Taking a project with 100 10m x 10m foundation pits as an example, the cost of traditional water-retaining edges would exceed one million yuan, while modular water-retaining edges can be purchased in batches of 400 meters to meet the needs of the entire project, costing less than 50,000 yuan. Moreover, they can be used for the next project after the project is completed, achieving long-term use with a one-time investment. The construction of traditional water-retaining edges is time-consuming and labor-intensive. Two skilled workers can only complete the construction of one 10m x 10m foundation pit water-retaining edge in a whole day, while modular water-retaining edges can be set up by two laborers in about 30 minutes.

[0043] Example 2:

[0044] This implementation proposes a modular water-retaining edge. The other structures are the same as in Example 1, except that the structures of the tenon and mortise are specified, such as... Figure 3 As shown, the width of the head of the tenon 3 is greater than the width of the base. The structure of the mortise 4 matches the structure of the tenon 3, that is, the width of the inner groove of the mortise 4 is greater than the width of the outer groove. When in use, the tenon 3 of the modular water-blocking edge is inserted through the upper part of the mortise 4 of another modular water-blocking edge until the two modular water-blocking edges are flush.

[0045] Example 3:

[0046] This utility model embodiment 3 provides a basic construction water-retaining system, including multiple modular water-retaining edges as described in this utility model embodiment 1 or embodiment 2. Each modular water-retaining edge is connected in sequence by tenons and mortises to form a rectangular water-retaining system, preventing water from seeping into the foundation pit.

[0047] The right-angle section of the rectangular water-blocking system uses a 90° connecting plate (here, a steel plate is used) to connect two adjacent modular water-blocking edges. The two sides of the 90° connecting plate are provided with mortises and tenons respectively.

[0048] In this implementation, preferably, the bottom of the 90° connecting plate can also be connected to a metal rod (welded or integrally formed) to ensure the stability of the entire foundation construction water-blocking system.

[0049] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
