Description

Technical Field

[0001] This application belongs to the field of building waterproofing technology, and in particular relates to a building foundation waterproofing and reinforcement structure. Background Technology

[0002] Building foundations are divided into natural foundations and artificial foundations. A natural foundation is a foundation that can directly bear the load of a building without any treatment. Conversely, an artificial foundation is a foundation that requires treatment using foundation treatment techniques. To prevent groundwater from entering the structure or building and affecting its quality and safe use, waterproofing treatment must be carried out during the construction of artificial foundations. This is generally done by laying waterproof membrane at the bottom of the artificial foundation.

[0003] Existing methods for waterproofing and drainage in foundations require excessive time to construct, thus unexpectedly extending the construction period, resulting in a huge construction cost burden and economic losses due to delays. Therefore, there is an urgent need for a ground improvement method that can quickly, continuously, and smoothly drain and block water during foundation construction on excavated ground. Utility Model Content

[0004] The purpose of this application is to address the aforementioned technical problems by providing a building foundation waterproofing and reinforcement structure that can improve the waterproofing and drainage performance of the building foundation.

[0005] This application provides a waterproofing and reinforcement structure for building foundations, including a foundation pit, and further comprising:

[0006] The first permeable layer is spread at the bottom of the foundation pit;

[0007] The first filling layer is placed above the first permeation layer;

[0008] The second permeation layer is placed above the first filling layer;

[0009] The sand layer is placed above the second permeable layer;

[0010] A waterproof layer is placed on top of the sand layer;

[0011] The second filler layer is placed on top of the waterproof layer;

[0012] A drainage mechanism, connected to the second permeable layer, is used to drain water that has permeated upwards. The drainage mechanism includes a drainage component, a cover, and a support assembly. The drainage component and the cover are connected by fasteners.

[0013] The drainage component and the cover are respectively placed on both sides of the second permeable layer, and the drainage component is provided with a drainage groove for water flow.

[0014] The first permeable layer, made of non-woven or synthetic fiber fabric, is used to quickly remove water from gaps that drain onto the surface during the leveling process. Besides absorbing and guiding water upwards, it also acts as a horizontal drainage material when large amounts of water flow from the groundwater layer, providing a bypass path for the groundwater. Groundwater passing through the first permeable layer continues to be guided upwards into the first fill layer. This also facilitates the installation of drainage mechanisms within the first fill layer, which consists of backfilled soil from the excavated pit. The second permeable layer absorbs water from the sand layer and the first fill layer, and connects to the drainage mechanism to guide the water to… In the drainage mechanism, groundwater is quickly guided out through the drainage channel. The second permeable layer is sandwiched between the drainage component and the cover, and the drainage component and the cover are connected by fasteners such as bolts or screws to improve the connection stability between the drainage mechanism and the second permeable layer. The support components improve the structural stability between the drainage mechanism and the first filling layer. The sand layer has a low water absorption rate, which can inhibit the upward flow of water and improve the bearing capacity of the foundation. The waterproof layer is made of waterproof materials such as PE or PP. The waterproof layer completely blocks the flow of water between the sand layer and the second filling layer, so that the groundwater will not continue to flow upward.

[0015] Furthermore, the cover includes:

[0016] The protrusion is pressed down so that it abuts against the second permeable layer after the cover is installed, thereby securing the second permeable layer to the drainage mechanism.

[0017] The pressing protrusion is integrally connected to the cover. After the cover is installed and connected to the drainage component, the pressing protrusion abuts against the second permeable layer to securely connect the second permeable layer to the drainage mechanism, while also making it easy for water in the second permeable layer to drip into the drainage trough.

[0018] Furthermore, the drainage component includes:

[0019] The support is placed in the drainage groove and is used to connect with the cover.

[0020] The support and the drainage component are integrally connected. The support is used for the installation connection of the cover. The support has threaded holes that correspond to fasteners. The support improves the overall structural strength of the drainage component.

[0021] Furthermore, the support component includes:

[0022] Support column, connected to the bottom of the drainage component.

[0023] The support column is set at the bottom of the drainage component, which is placed above the first filling layer. The support column is inserted into the first filling layer to improve the connection stability between the drainage component and the first filling layer.

[0024] Furthermore, the support column and the drainage component are connected by threads or by welding.

[0025] If a threaded connection is used between the support column and the drainage component, it facilitates the movement and transportation of the support column and the drainage component. If a welded connection is used between the support column and the drainage component, it improves the stability of the connection between the support column and the drainage component.

[0026] Furthermore, the support component also includes:

[0027] The stepped base, placed on the support column, is used to enhance the support of the first filling layer for the support components.

[0028] At least three stepped seats are movably installed on the support column. During transportation, the stepped seats are aligned with each other and have the same axis. During use, the stepped seats are rotated to make them radiate outwards, further increasing the structural stability between the support column and the first filling layer.

[0029] Furthermore, the stepped base includes:

[0030] The movable part is located at the end of the step base and away from the support column.

[0031] The movable component is movably connected to the step base. When in use, the movable component extends from the end of the step base, further increasing the contact area between the step base and the first filling layer, and further improving the structural stability between the support column and the first filling layer.

[0032] Furthermore, the movable component is telescopically connected or hinged to the stepped base.

[0033] If the movable part and the step base are connected by a telescopic connection, the movable part extends from the end of the step base during use;

[0034] If the movable part is hinged to the step base, the movable part will rotate upward from the bottom end of the step base during use.

[0035] The beneficial effects of this application are:

[0036] 1. The second permeable layer is connected to the drainage mechanism to guide water into the drainage mechanism, and then the groundwater is quickly discharged through the drainage channel.

[0037] 2. The second permeable layer is sandwiched between the drainage component and the cover, and the drainage component and the cover are connected by fasteners such as bolts or screws, which improves the connection stability between the drainage mechanism and the second permeable layer.

[0038] 3. Improve the structural stability between the drainage mechanism and the first filling layer by using support components. Attached Figure Description

[0045] The embodiments of this application are described in detail below with reference to the accompanying drawings, through specific examples and application scenarios.

[0046] Example 1:

[0047] like Figure 1 , Figure 2 As shown in the figure, this application embodiment provides a building foundation waterproofing and reinforcement structure, including a foundation pit 100, and further including:

[0048] The first permeable layer 200 is spread at the bottom of the foundation pit 100;

[0049] The first filling layer 300 is placed above the first permeable layer 200;

[0050] The second permeation layer 400 is placed above the first filling layer 300;

[0051] The sand layer is 500mm thick and placed above the second permeable layer of 400mm.

[0052] A 600mm waterproof layer is placed on top of a 500mm sand layer;

[0053] The second filler layer 700 is placed on top of the waterproof layer 600;

[0054] A drainage mechanism 800, connected to the second permeable layer 400, is used to drain water that has permeated upwards. The drainage mechanism 800 includes a drainage component 810, a cover 820, and a support assembly 830. The drainage component 810 and the cover 820 are connected by fasteners.

[0055] The drainage component 810 and the cover 820 are respectively placed on both sides of the second permeable layer 400, and the drainage component 810 is provided with a drainage groove 811 for water flow.

[0056] The first permeable layer 200, made of non-woven or synthetic fiber fabric, can be used to quickly remove water from gaps that drain onto the surface during the leveling process. Besides absorbing and guiding water upwards, the first permeable layer 200 also acts as a horizontal drainage material when large amounts of water flow in from the groundwater layer, providing a bypass path for the groundwater. Groundwater passing through the first permeable layer 200 continues to be guided upwards through the first filling layer 300. This also facilitates the installation of the drainage mechanism 800 within the first filling layer 300, which includes backfilling the soil excavated from the foundation pit 100. The second permeable layer 400 absorbs water from the sand layer 500 and the first filling layer 300. The second permeable layer 400 connects to the drainage mechanism 800, thus guiding the water to the drainage mechanism 800. In the middle, the groundwater is then quickly guided out through the drainage channel 811. The second permeable layer 400 is sandwiched between the drainage component 810 and the cover 820, and the drainage component 810 and the cover 820 are connected by fasteners such as bolts or screws, which improves the connection stability between the drainage mechanism 800 and the second permeable layer 400. The support component 830 improves the structural stability between the drainage mechanism 800 and the first filling layer 300. The sand layer 500 has a low water absorption rate, which can inhibit the upward guidance of water. The sand layer 500 can also improve the bearing capacity of the foundation. The waterproof layer 600 is made of waterproof materials such as PE or PP. The waterproof layer 600 completely blocks the flow of water between the sand layer 500 and the second filling layer 700, so that the groundwater will not continue to be guided upward.

[0057] Furthermore, the cover 820 includes:

[0058] The protrusion 821 is pressed down so that after the cover 820 is installed, it abuts against the second permeable layer 400 to securely connect the second permeable layer 400 to the drainage mechanism 800.

[0059] The pressing protrusion 821 is integrally connected with the cover 820. After the cover 820 is installed and connected with the drainage component 810, the pressing protrusion 821 abuts against the second permeable layer 400 to securely connect the second permeable layer 400 with the drainage mechanism 800, and at the same time make it easy for the water in the second permeable layer 400 to drip into the drainage groove 811.

[0060] Furthermore, the drainage component 810 includes:

[0061] The support part 812 is placed in the drainage groove 811 and is used to connect with the cover 820.

[0062] The support part 812 is integrally connected with the drainage part 810. The support part 812 is used for the installation connection of the cover 820. The support part 812 has threaded holes that correspond to fasteners. The support part 812 improves the overall structural strength of the drainage part 810.

[0063] Example 2:

[0065] The support column 831 is connected to the bottom of the drainage component 810.

[0066] The support column 831 is located at the bottom of the drainage component 810, which is positioned above the first filling layer 300. The support column 831 is inserted into the first filling layer 300 to improve the connection stability between the drainage component 810 and the first filling layer 300.

[0067] Furthermore, the support column 831 and the drainage component 810 are connected by threads or by welding.

[0068] If a threaded connection is used between the support column 831 and the drainage component 810, it facilitates the movement and transportation of the support column 831 and the drainage component 810. If a welded connection is used between the support column 831 and the drainage component 810, it improves the stability of the connection between the support column 831 and the drainage component 810.

[0069] Furthermore, the support component 830 also includes:

[0070] The stepped seat 832 is placed on the support column 831 to enhance the support of the first filling layer 300 to the support component 830.

[0071] At least three stepped seats 832 are movably installed on the support column 831. During transportation, the stepped seats 832 are aligned with each other and have the same axis. During use, the stepped seats 832 are rotated to make them radiate outwards, further increasing the structural stability between the support column 831 and the first filling layer 300.

[0072] Furthermore, the stepped base 832 includes:

[0073] The movable part 833 is located at the end of the step seat 832 and away from the end of the support column 831.

[0074] The movable part 833 is movably connected to the step base 832. When in use, the movable part 833 extends from the end of the step base 832, further increasing the contact area between the step base 832 and the first filling layer 300, and further improving the structural stability between the support column 831 and the first filling layer 300.

[0075] Furthermore, the movable component 833 is telescopically connected or hinged to the stepped base 832.

[0076] If the movable part 833 and the step seat 832 are connected by a telescopic connection, the movable part 833 extends from the end of the step seat 832 during use;

[0077] If the movable part 833 and the step seat 832 are hinged, the movable part 833 will rotate upward from the bottom end of the step seat 832 during use.
