Description

Technical Field

[0001] This utility model relates to the field of ground structure technology, and in particular to a ground structure. Background Technology

[0002] Ground structures generally refer to the geological, geomorphological, and artificially modified structures on the surface and shallow underground within urban areas and areas of human activity.

[0003] Currently, to prevent ground subsidence and cracking, as well as to prevent leakage and dampness, the treatment methods used for the ancient Qin Dynasty's "Chidao" (imperial roads) are often adopted to handle the ground structure. For example, plain soil is backfilled and compacted to ensure that the foundation will not easily subside in the future.

[0004] However, during the construction process, some interior spaces also require the construction of ground structures. Due to the limited interior space, many interior spaces do not meet the conditions for construction, which means that the compaction of backfill soil must be done manually. This not only increases the requirements for compaction technology, but also easily leads to poor compaction results. In addition, the traditional ground surface layer is only equipped with a single layer of steel mesh, which limits its strength. As a result, over time, the ground surface layer is prone to hollowing or collapse (ground surface collapse) due to thermal expansion and contraction of the backfill layer. Utility Model Content

[0005] The main purpose of this utility model is to provide a ground structure that addresses the problem of hollowing or collapse of the floor surface in indoor spaces due to insufficient strength and poor compaction of the backfill layer.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A ground structure includes, from bottom to top, a backfill layer, a mortar layer, a concrete subbase layer, and a concrete surface layer. The concrete surface layer is provided with a steel mesh, and there are at least two steel meshes. A plurality of first supports and a plurality of second supports are provided between adjacent steel meshes, and each second support is detachably connected between adjacent steel meshes.

[0008] Furthermore, a waterproof layer is provided between the concrete subbase and the concrete surface layer.

[0009] Furthermore, the waterproof layer is provided with several pads.

[0010] Furthermore, each of the second trestles includes a first support arm, a second support arm, and an abutment beam, with each abutment beam rotatably connected between the first support arm and the second support arm.

[0011] Furthermore, each of the first support arms is fixedly connected to each abutment beam.

[0012] Furthermore, the second support arm is provided with a solidification groove, and the abutment beam is rotatably connected in the solidification groove.

[0013] Furthermore, each of the abutting beams is provided with a mating block at one end located in the solidification groove. Each mating block is rotatably connected to the solidification groove in a corresponding manner. The projection surfaces of each solidification groove and each mating block in the axial direction of the rotation axis of the abutting beam are all polygonal structures.

[0014] Furthermore, the longitudinal section of each of the pads is a "T" shaped structure.

[0015] Furthermore, each of the pads is provided with a reinforcing hole, and a reinforcing pin is provided in the reinforcing hole, and the reinforcing pin is slidably connected to the reinforcing hole.

[0016] Furthermore, each of the first trestles is provided with a first limiting block and a first limiting groove at both ends; each of the second trestles is provided with a second limiting block and a second limiting groove at both ends.

[0017] The working principle and beneficial effects of this utility model are as follows:

[0018] This utility model's technical solution strengthens the concrete surface layer (ground surface layer) by setting several steel meshes in it, thereby enhancing its plasticity and flexibility. This strengthens the rigidity and elasticity of the concrete surface layer, making it more resistant to the destructive effects of external forces (human trampling, thermal expansion and contraction of the backfill layer, etc.), and effectively avoids the problems of hollowing or collapse of the ground surface layer under the influence of the compaction effect of the backfill layer and the action of external forces.

[0019] Meanwhile, to ensure the effectiveness of each steel mesh, several first supports are installed between adjacent steel meshes. However, considering calculation errors, it may be found during later inspections that the pre-installed first supports provide limited support to the steel mesh, necessitating the dismantling of the steel mesh and the installation of additional supports, resulting in low construction efficiency for the ground structure. Therefore, this utility model solution also includes several second supports between adjacent steel meshes. Each second support is detachable and connectable to the adjacent steel meshes, allowing for the addition of supports without removing the steel meshes, effectively improving the construction efficiency of the ground structure.

[0030] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0032] like Figures 1-3As shown in the figure, this embodiment proposes a ground structure, mainly including a backfill layer 1, a mortar layer 2, a concrete cushion layer 3, and a concrete surface layer 4 distributed from bottom to top. The concrete surface layer 4 is equipped with a steel mesh 5. Before backfilling, the backfill soil in the backfill layer 1 should be sun-dried to effectively remove the moisture content and allow the organic matter and humus in the backfill soil to dry, preventing fermentation and expansion after backfilling. The concrete cushion layer 3 can prevent plant seeds in the backfill soil that have not been killed by sun exposure from germinating and breaking through the concrete cushion layer 3 above. It can also prevent groundwater from seeping into the ground due to excessive groundwater levels, causing mold and moisture. The presence of the mortar layer 2 can effectively support the relatively fragile concrete cushion layer 3 above it, preventing the concrete cushion layer 3 from sinking excessively and breaking under the pressure from above, ensuring that the concrete cushion layer 3 can provide strong support for the concrete surface layer 4 (ground surface layer) and the steel mesh 5 located inside it.

[0033] Meanwhile, a waterproof layer 8 is provided between the concrete subbase 3 and the concrete surface layer 4. The waterproof layer 8 is preferably an asphalt waterproof membrane. The physical waterproof properties of the waterproof layer 8 are used to further improve the ability of this embodiment to prevent dampness and water leakage.

[0034] Furthermore, several spacers 81 are provided on the waterproof layer 8, with each reinforcing mesh 5 located above the spacers 81. The physical barrier effect of the spacers 81 ensures sufficient spacing between the lower reinforcing mesh and the waterproof layer 8. This ensures adequate concrete between the waterproof layer 8 and the lower reinforcing mesh during concrete pouring, effectively guaranteeing the concrete's containment of the reinforcing mesh 5 after it hardens. Preferably, each spacer 81 is integrally formed with the waterproof layer 8 to ensure reliable connection between the two.

[0035] Preferably, in this embodiment, the longitudinal section of each pad 81 is a "T" shaped structure, so that after the concrete around each pad 81 solidifies, it can form a groove that fits into the pad 81, thereby fixing the pad 81 and the waterproof layer 8 that is fixedly connected to the pad 81.

[0036] To enhance the strength of the concrete surface layer 4, at least two reinforcing meshes 5 are installed within it. Furthermore, to ensure that each reinforcing mesh 5 maintains its designed position during concrete pouring and to prevent downward displacement due to construction loads or concrete impact, several first supports 6 are installed between adjacent reinforcing meshes 5. During installation and construction, due to the structure of the traditional supports (first supports 6), the installation sequence is limited to "lower reinforcing mesh - first supports 6 - upper reinforcing mesh." This sequence firmly confines the first supports 6 between adjacent reinforcing meshes 5. However, during actual installation (in the inspection phase), due to calculation errors and other reasons, some areas of the reinforcing mesh 5 cannot be effectively supported. Therefore, it is necessary to add supports to adjacent reinforcing meshes 5. Because of the traditional connection method between the supports and the reinforcing mesh 5, the upper reinforcing mesh needs to be dismantled when adding or supplementing the traditional supports, thus affecting the overall construction efficiency of the ground structure.

[0037] Therefore, in this embodiment, several second supports 7 are provided between adjacent steel meshes 5. Each second support 7 is detachably connected between adjacent steel meshes 5. By taking advantage of the detachable connection between the second support 7 and the steel mesh 5, the second support 7 can be added between adjacent steel meshes 5 without removing the upper steel mesh. This ensures both the structural strength of the ground surface layer (concrete surface layer 4) and the construction efficiency of the ground structure.

[0038] In this embodiment, the second support 7 does not directly contact the steel mesh 5. Instead, the two only come into contact when the steel mesh 5 is deformed to a certain extent. That is, the steel mesh 5 will come into contact with the second support 7 during the deformation process. In this way, the strength of the concrete surface layer 4 is indirectly improved by using the physical barrier effect of each second support 7 to limit the deformation of the steel mesh 5.

[0039] like Figures 3-7 As shown, each second support trestle 7 includes a first support arm 71, a second support arm 72, and an abutment beam 73. Each abutment beam 73 is rotatably connected between the first support arm 71 and the second support arm 72, meaning the second support trestle 7 has a modular design. During installation, the first support arm 71 or the second support arm 72 can be rotated so that the abutment surfaces of the first support arm 71 or the second support arm 72 and the abutment beam 73, which are used for abutting the upper layer of reinforcing mesh, are parallel to each other. This prevents the presence of the first support arm 71 or the second support arm 72 from interfering with the rotational movement of the second support trestle 7 with the reinforcing bars of the lower layer of reinforcing mesh as the center. The second support trestle 7 can then rotate with the reinforcing bars of the lower layer of reinforcing mesh as the center until the bottom surface of the second support trestle 7 is parallel to the lower layer of reinforcing mesh. Afterward, the previously rotated first support arm 71 or the second support arm 72 returns to its original position, and the second support trestle 7 moves along the axial direction of the reinforcing bars until it is above the pad block 81, thus completing the installation of the second support trestle 7.

[0040] Correspondingly, considering that the spacer 81 and the waterproof layer 8 are integrally formed, the spacer 81 itself is relatively soft and is prone to deformation when subjected to pressure (such as the force from the second trestle 7 and the steel mesh 5), which reduces or even eliminates the space between the spacer 81 and the waterproof layer 8 for concrete to flow in, resulting in a decrease in the fixing effect of the concrete surface layer 4 on the waterproof layer 8.

[0041] Therefore, each pad 81 is provided with a reinforcing hole 82, and a reinforcing pin 9 is provided in the reinforcing hole 82. The reinforcing pin 9 is slidably connected to the reinforcing hole 82. In this way, when the reinforcing pin 9 is inserted inside the reinforcing hole 82, the reinforcing pin 9 can be used to resist the pressure from above and reduce the degree of deformation of each pad 81.

[0042] Each first support arm 71 is fixedly connected to each abutment beam 73, meaning that the operator can rotate the first support arm 71 and the abutment beam 73 simultaneously, which effectively improves the adjustment efficiency between the modules of the second trestle 7, and thus effectively improves the installation efficiency of the second trestle 7 in this embodiment.

[0043] The second support arm 72 is provided with a solidification groove 721, and the abutment beam 73 is rotatably connected to the solidification groove 721. That is, the second support arm 72 has a space for concrete to flow in. In this way, when pouring concrete, concrete will flow into the interior of the second support arm 72, forming a block between the abutment beam 73 and the solidification groove 721, restricting the rotational movement between the second support arm 72 and the abutment beam 73, thereby ensuring the overall structural stability of the second support 7 after cement is poured.

[0044] Correspondingly, each abutting beam 73 is provided with a mating block 731 at one end of the solidification slot 721. Each mating block 731 is rotatably connected to the solidification slot 721, that is, the block is located between the mating block 731 and the solidification slot 721. At the same time, the projection surfaces of each solidification slot 721 and each mating block 731 in the axial direction of the rotation axis of the abutting beam 73 are all polygonal structures. That is, the projection surface of the block between the mating block 731 and the solidification slot 721 also presents a polygonal structure, so that there is a rigid constraint effect between the three, which strengthens the fixing effect of the solidified concrete (block) on the second support arm 72.

[0045] like Figure 4 , Figure 7 As shown, each of the first supports 6 has a limiting block 61 and a limiting groove 62 at both ends. The limiting block 61 is located on the side of the first support 6 away from the waterproof layer 8, so that when the steel mesh 5 needs to be added in sequence, the corresponding first supports 6 can be interlocked with each other, thereby constraining the position of each steel mesh 5 and ensuring the positional stability between each steel mesh 5.

[0046] If necessary, after the concrete surface layer 4 has solidified, the base tiles can be laid on the concrete surface layer 4 to ensure the aesthetics of this embodiment.
