Description

Technical Field

[0001] The utility model belongs to the technical field of foundation reinforcement, and in particular relates to a novel reinforced foundation. Background Art

[0002] At present, reinforced foundation refers to the bearing layer composed of reinforcement materials laid layer by layer in the fill soil under the foundation. Compared with unreinforced foundation, reinforced foundation can significantly improve the bearing capacity of foundation, reduce the settlement and uneven settlement of foundation. In recent years, with the development and application of geosynthetics (such as geogrids, geocells, geotextiles, geobelts and geonets, etc.), geosynthetics reinforced soil foundation has been widely used in many engineering fields such as construction, transportation, water conservancy, etc. At present, many scholars at home and abroad have carried out experiments and numerical simulations to study the deformation and bearing performance of reinforced foundations, and explored the optimal reinforcement arrangement parameters to achieve the best reinforcement effect of reinforcement materials. In terms of theoretical research, most scholars use limit equilibrium or limit analysis methods to derive the calculation formulas for settlement and bearing capacity of reinforced foundations. However, in the current research, the reinforcement materials in the reinforced foundation are all the same kind of reinforcement materials, which have the same length, stiffness and strength, and each layer of reinforcement materials maintains the same interlayer spacing during the laying process. In the design of reinforced foundation, the same kind of reinforcement with the same stiffness, strength and length is used according to the research results, and the interlayer spacing is consistent. However, through experiments and numerical simulation studies, it is found that not every layer of reinforcement in the reinforced foundation can fully exert its own reinforcement effect, and the tension of each layer of reinforcement is not equal. Therefore, setting each layer of reinforcement to the same length, stiffness, strength and interlayer spacing will cause material waste and increase engineering costs. In view of this, there is an urgent need for a new reinforced foundation structure that can maximize the reinforcement effect of each layer of reinforcement in the reinforced foundation and save costs.

[0003] Existing technology: traditional reinforced foundation technology

[0004] Traditional reinforced foundation technology mainly involves laying a single type of reinforcement material (usually geosynthetics) in the foundation fill to improve the bearing capacity and stability of the foundation. This method usually uses reinforcement materials of standard size and strength, and fixed laying spacing.

[0005] Existing technical problems:

[0006] 1) Lack of reinforcement diversity: Traditional technologies usually use only a single type or specification of reinforcement, which limits its applicability and reinforcement effect under different soil and loading conditions.

[0007] 2) Lack of flexibility: Due to the single type of reinforcement material and laying method, this traditional technology lacks flexibility when dealing with complex or changing geological conditions and may not achieve the best reinforcement effect.

[0008] 3) Bearing capacity limitations: Under certain special engineering conditions, such as extremely soft soil or high load requirements, a single type of reinforcement may not be able to meet the bearing requirements of the project.

[0009] 4) Engineering adaptability issues: Due to the lack of reinforcement material optimization for specific engineering needs, traditional reinforced foundation technology may not be able to fully exert its potential reinforcement effect, especially in complex engineering geological environments.

[0010] In summary, although the traditional reinforced foundation technology can effectively improve the stability of the foundation under normal circumstances, it has certain limitations in terms of the diversity, flexibility, bearing capacity and engineering adaptability of the reinforcement materials. These problems limit its application effect under more complex and special engineering conditions. Utility Model Content

[0019] 2) Optimized interlayer spacing: The interlayer spacing of each layer of reinforcement is different, providing greater flexibility and adjustment space. This allows the foundation design to be optimized according to specific geological and loading conditions, thereby more effectively improving the overall performance of the foundation.

[0020] 3) Construction flexibility: The new reinforced foundation allows different layer spacing and reinforcement lengths to be adjusted according to design requirements during the actual construction process.

[0027] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail in combination with the embodiments below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0028] In the present invention, the reinforced foundation uses reinforcement materials (usually geosynthetics) to increase the overall stability, bearing capacity and deformation resistance of the foundation. The following are two specific application examples:

[0029] Example 1: Highway roadbed reinforcement

[0030] In highway construction, especially in soft soil areas, the roadbed needs additional reinforcement to ensure stability and bearing capacity. For this application, high stiffness (J1) and high strength (T1) reinforcement can be selected, as well as a larger length (L1) to ensure the stability of the entire roadbed structure.

[0031] 1) Reinforcement material selection: Select reinforcement with high strength (T1) and high stiffness (J1), and a length (L1) sufficient to span the entire width of the roadbed.

[0032] 2) Interlayer spacing: Depending on the depth of the soft soil layer and the design load of the roadbed, a smaller interlayer spacing (h1) may be required to provide more support.

[0033] 3) Construction steps:

[0034] The first layer of reinforcement is laid at the bottom of the pre-compacted fill 4.

[0035] Add 4 layers of new fill and compact.

[0036] Continue to alternately lay 3 layers of reinforcement and 4 layers of fill until the designed height is reached.

[0037] 4) After completion: the pavement structure layer is laid on the fill surface 2, and then the pavement paving work can be carried out.

[0038] Example 2: Building foundation reinforcement

[0039] In construction projects, reinforced foundations can provide additional support for buildings that require higher foundation bearing capacity, such as multi-story buildings or heavy industrial facilities.

[0040] 1) Reinforcement material selection: Select reinforcement materials with different stiffness (J2, J3) and strength (T2, T3). The length (L2, L3) is determined according to the size of the foundation.

[0041] 2) Interlayer spacing: The interlayer spacing (h2, h3) is determined based on the expected load of the building and the properties of the foundation soil, and may require a closer reinforcement arrangement to meet higher load-bearing requirements.

[0042] 3) Construction steps:

[0043] Lay the first layer of reinforcement material at the bottom of the foundation fill 4.

[0044] Compact the new fill layer and continue laying the reinforcement.

[0045] After each layer of reinforcement is laid, the soil needs to be compacted.

[0046] Repeat the above process until the desired height is reached.

[0047] 4) Upon completion: the building's foundation structure 1 is constructed on the top fill surface 2.

[0048] In both embodiments, the length, stiffness, strength and layer spacing of the reinforcement are customized according to the foundation conditions and structural load requirements. By adjusting these parameters, suitable reinforcement solutions can be provided for different engineering needs to ensure the stability and safety of the structure.

[0049] like Figure 1 As shown, the new reinforced foundation provided by the embodiment of the utility model includes: reinforcement material 3 and foundation fill 4. In the structure, the reinforcement material 3 is a geosynthetic material with different lengths L1, L2, L3, different stiffness J1, J2, J3 and different strengths T1, T2, T3, and the interlayer spacing of each layer of reinforcement material is different h1, h2, h3. During the construction process of the reinforced foundation, the reinforcement material 3 should be laid layer by layer in the foundation fill 4 according to the actual design requirements, and the foundation fill 4 needs to be compacted. After the construction of the reinforced foundation is completed, the foundation 1 can be placed on the fill surface 2. In the actual construction process, different interlayer spacings h1, h2, h3 and reinforcement material lengths L1, L2, L3 can be adjusted according to the design requirements, and reinforcement materials with corresponding stiffness J1, J2, J3 and strength T1, T2, T3 that meet the requirements can be selected.

[0050] The working principle of the utility model is that during the construction of the reinforced foundation, the reinforcement material 3 should be laid layer by layer in the foundation fill 4 according to the actual design requirements and the foundation fill 4 needs to be compacted. After the construction of the reinforced foundation is completed, the foundation 1 can be placed on the fill surface 2.

[0051] The working principle of the reinforced foundation of the utility model mainly involves the following key aspects:

[0052] 1) Use of reinforcement:

[0053] Diversity: The reinforcement 3 is made of geosynthetics with different lengths L1, L2, L3, different stiffnesses J1, J2, J3 and different strengths T1, T2, T3. These reinforcements with different characteristics can be selected and matched according to the specific requirements of the land and the building.

[0054] Layered laying: The reinforcement is laid in layers in the foundation fill 4, and the spacing h1, h2, h3 between each layer of reinforcement can be adjusted according to the project requirements. This layered arrangement enhances the overall stability and bearing capacity of the foundation.

[0055] 2) Compaction of foundation fill:

[0056] In the process of laying the reinforcement, the foundation fill 4 needs to be properly compacted. Doing so helps to improve the density of the fill, so that the reinforcement and the soil are better combined, thereby improving the bearing capacity and stability of the foundation.

[0057] 3) Improvement of foundation bearing capacity:

[0058] The main purpose of reinforced foundation is to enhance the bearing capacity of the foundation. By laying reinforcement materials layer by layer in the fill soil, the load can be effectively dispersed, the foundation settlement can be reduced, and the overall stability of the foundation can be improved.

[0059] 4) Adaptability and flexibility:

[0060] The design of the reinforced foundation allows the length, spacing, stiffness and strength of the reinforcement to be flexibly adjusted according to the design requirements and site conditions during the actual construction process. This flexibility makes the reinforced foundation suitable for a variety of soil types and load conditions.

[0061] In summary, the reinforced foundation of the utility model effectively improves the stability and bearing capacity of the foundation by using reinforcement materials with different characteristics and laying and compacting them in layers in the foundation fill. This reinforced foundation structure is suitable for various land conditions and construction requirements, and provides a more reliable and efficient foundation solution for infrastructure construction.

[0062] The specific implementation method of the utility model is as follows:

[0063] Step 1: Choose the right reinforcement material

[0064] 1) Selection of reinforcement materials:

[0065] According to the engineering design requirements, geosynthetics with different lengths L1, L2, L3, different stiffnesses J1, J2, J3 and different strengths T1, T2, T3 are selected as reinforcement materials.

[0066] Determine the specific parameters of each reinforcement material to adapt to different geological conditions and load-bearing requirements.

[0067] Step 2: Determination of interlayer spacing

[0068] 1) Layer spacing design:

[0069] The interlayer spacing h1, h2, and h3 of each layer of reinforcement is designed to ensure the overall stability of the reinforced foundation and uniform force distribution.

[0070] The design of the layer spacing should be based on the depth of the foundation, the required bearing capacity and the soil conditions.

[0071] Step 3: Laying the reinforcement

[0072] 1) Preparation for laying:

[0073] Before starting to lay the reinforcement, carry out preparatory work for the foundation fill to ensure that the ground is level.

[0074] 2) Layered laying:

[0075] Lay reinforcement materials of different specifications in sequence according to the predetermined layer spacing h1, h2, and h3 to ensure that each layer of reinforcement material is evenly laid and tightly combined with the fill.

[0076] Step 4: Filling and compacting the foundation

[0077] 1) Filling and compaction:

[0078] After laying each layer of reinforcement, the foundation is filled and moderately compacted to enhance the interaction between the reinforcement and the soil.

[0079] Repeat this process until all layers of reinforcement are laid.

[0080] Step 5: Implement inspection and adjustment

[0081] 1) Inspection and adjustment:

[0082] After the reinforced foundation is constructed, the structural integrity and stability are checked.

[0083] If necessary, make appropriate adjustments to the reinforcement arrangement or compaction degree based on actual conditions.

[0084] Through the above steps, a reinforced foundation can be realized which is adjusted according to specific engineering requirements and has reinforcement materials of different lengths, stiffnesses and strengths, thereby improving the bearing capacity and stability of the foundation.

[0085] Geosynthetics are a type of material used in civil engineering to reinforce soil and improve the bearing capacity of land. They are mainly used in roadbed reinforcement, dam construction, landslide control, foundation reinforcement, drainage systems, and environmental protection projects. The following are examples of geosynthetics that can be used in this utility model:

[0086] 1) Geotextiles: This material has good water permeability and can be used for separation, filtration, reinforcement, protection and drainage. It is divided into two categories: non-woven geotextiles and woven geotextiles.

[0087] 2) Geonets: A three-dimensional mesh material used for drainage that can effectively collect and discharge liquids and gases.

[0088] 3) Geogrids: This material is mainly used for foundation reinforcement and roadbed reinforcement. It has high tensile strength and can effectively disperse the load and increase the stability of the foundation.

[0089] 4) Geocells: A three-dimensional mesh structure made of high-strength strips welded together. After being filled with soil, stone or concrete, it can be used to reinforce roadbeds, embankments, slope protection, etc.

[0090] 5) Geocomposites: These are products that combine two or more different types of geosynthetics, such as geotextiles and geogrids, which can simultaneously achieve the functions of isolation, permeability and reinforcement.
