[0024] As Figures 1-4 shown:

[0025] A light high-strength flexible static load counter-pressure structure comprises a bearing table 101 arranged at the top of a pile to be tested;

[0026] The top of the bearing table 101 is sequentially stacked with a plurality of groups of geotextile bodies 102, the geotextile body 102 comprises a bag body 1021 in an open structure and a sealing surface 1022 integrally arranged at the four sides of the opening of the bag body 1021;

[0027] The opposite sealing surfaces 1022 are respectively fixed with a plurality of groups of hook-faced magic tapes 1024 and fuzzy-faced magic tapes 1023, the hook-faced magic tapes 1024 and the fuzzy-faced magic tapes 1023 correspond to each other, and the hook-faced magic tapes 1024 and the fuzzy-faced magic tapes 1023 are used for connecting and locking the mutually corresponding sealing surfaces 1022 through the adhesion of the fuzzy-faced magic tapes 1023 and the hook-faced magic tapes 1024;

[0028] The inner cavity bottom of the bag body 1021 is fixed with a main body belt 1026 in a cross structure, the four end surfaces of the main body belt 1026 are all fixed with first connecting belts 1027, the inside of the bag body 1021 is provided with a fixed belt 1030, the top end of the fixed belt 1030 is fixed with a handle pull ring 1029, one end of the first connecting belt 1027 is fixedly connected with the fixed belt 1030, the inner cavity bottom of the bag body 1021 is fixed with four groups of second connecting belts 1028 in a cross structure, and one end of the second connecting belt 1028 is fixed with the first connecting belt 1027;

[0029] The second connecting belt 1028 corresponds to the position of the main body belt 1026, and the bottom of the bag body 1021 is fixed with a reinforcing sheet 1025 for enhancing the bearing capacity of the bottom of the bag body 1021;

[0030] The geotextile body 102 is made of flexible material, the flexible material is woven from non-woven geotextile, and is designed to collect and package sand, stone and soil materials at a construction site to form counterweights.

[0031] In the embodiment, when the counterweight is stacked on the top of the bearing table 101 in use;

[0032] As Figure 5As shown: first, the geotextile bag body 102 is placed in the support template frame, through the setting of the support template frame, the geotextile bag body 102 can better adapt to and fill the specific space shape, and at the same time, the material can be better filled into the geotextile bag body 102;

[0033] After the bag body 1021 of the geotextile bag body 102 is placed in the support template frame, the sealing surface 1022 is spread out to facilitate the addition of materials, then the handle pull ring 1029 is pulled up, the rod (not shown in the figure) passes through the handle pull ring 1029, and the rod is placed on the support template frame to limit the handle pull ring 1029, so that the handle pull ring 1029 is not buried in the material during the addition of the material later, and the hoisting in the later period is not facilitated;

[0034] Then, the filling device (not shown in the figure) in the test area is used to fill sand, stone, soil and other materials in the bag body 1021. After the material filling in the bag body 1021 is completed, the opposite sealing surface 1022 is stacked, and the rough magic tape 1023 is bonded on the hook magic tape 1024, which is used to connect and lock the two groups of sealing surfaces 1022. Then, the other two groups of sealing surfaces 1022 are connected and locked, and the materials in the bag body 1021 are blocked by the folding of the four groups of sealing surfaces 1022, so that the material packaging is completed;

[0035] The hoist of the hoisting device is connected with the handle pull ring 1029, and the geotextile bag body 102 and the filled material are hoisted on the bearing table 101 by the hoisting device (not shown in the figure) for stacking;

[0036] Through the test area, the on-site materials can be used to save costs, especially for small and medium-sized static load in remote areas, which can enhance the competitiveness and reduce the cost and increase the effect of the structure;

[0037] Through the setting of the main body belt 1026, the first connecting belt 1027 and the second connecting belt 1028, the connection strength of the fixed belt 1030 and the bag body 1021 is increased. When the hoisting device lifts the handle pull ring 1029, the main body belt 1026, the first connecting belt 1027 and the second connecting belt 1028 are pulled upward by the fixed belt 1030. At this time, the bottom of the bag body 1021 forms a groove. When the geotextile bag body 102 is stacked and stacked, the groove structure can increase the friction and embedding effect between the geotextile bag bodies 102, improve the stability of the stacked and stacked structure, reduce the structural instability caused by movement or vibration, disperse and bear the pressure of the upper geotextile bag body 102, thereby improving the bearing capacity of the whole structure, making the erection more stable;

[0038] The bottom of the bag body 1021 is provided with a reinforcing piece 1025 in the shape of a cross. The reinforcing piece 1025 can increase the support area at the bottom of the bag body 1021, distribute and transfer weight, thereby improving the load-bearing capacity of the bag body 1021.

[0039] The working principle and usage process of this utility model are as follows: When using this lightweight, high-strength, flexible static load counter-pressure structure, after adding counterweights to the top of the support platform 101, firstly, the geotextile bag body 102 is placed inside the support template frame, and the sealing surface 1022 is unfolded to facilitate material addition. Then, the handle pull ring 1029 is pulled upwards. Next, materials such as sand, stone, and soil can be used to fill the bag body 1021 through the test area using a filling device (not shown in the figure). After filling the bag body 1021, the opposing sealing surfaces 1022 are stacked, and the hook and loop fasteners 1023 are attached. The hook and loop fastener 1024 is attached to the two sets of sealing surfaces 1022 for connection and locking. Then, through this operation, the other two sets of sealing surfaces 1022 are connected and locked. By folding and covering the four sets of sealing surfaces 1022, the material inside the bag body 1021 is sealed, thereby completing the material encapsulation. The lifting device is connected to the handle pull ring 1029. The geotextile bag body 102 and the filling material are lifted onto the support platform 101 by the lifting device (not shown in the figure) and stacked. This operation can be carried out by using materials on-site in the test area, which can make full use of the on-site materials as a reaction system device.

[0040] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
