Description

Technical Field

[0001] This utility model relates to the field of anchor cable support technology in geotechnical engineering, and in particular to a grouting and sealing bag suitable for miscellaneous fill soil layers. Background Technology

[0002] In the field of geotechnical engineering, grouting and sealing of anchor cables is a crucial step in ensuring the anchoring effect. Miscellaneous fill layers, due to their complex composition (a mixture of various construction wastes, domestic waste, clay, sand, etc.), are characterized by high porosity, strong heterogeneity, and poor soil stability. Existing grouting and sealing bags often face numerous problems when applied to miscellaneous fill layers. For example, the bags are difficult to adapt to the complex soil structure and are prone to cracking or sealing failure when the soil undergoes uneven deformation. Conventional bag materials may not effectively resist the erosion of corrosive substances that may be present in the miscellaneous fill layer, leading to premature bag damage, which in turn affects the grouting and sealing quality of the anchor cable, reduces the anchoring force, and threatens the stability of the engineering structure. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-3 This utility model provides an embodiment of a grouting and sealing bag suitable for miscellaneous fill layers, comprising a steel strand 1, a sealing bag body 2 disposed on the outer right side of the steel strand 1, an exhaust hole 6 opened on the left side of the sealing bag body 2, and fixing bag clamps 3 disposed on both the outer left and right sides of the sealing bag body 2, and several isolation supports 7 evenly disposed on opposite sides of the steel strand 1, a grouting assembly disposed on the left side of the sealing bag body 2, the grouting including a first grouting pipe 4 fixedly connected to the front left side of the sealing bag body 2, a second grouting pipe 5 fixedly connected to the middle left side of the sealing bag body 2, the fixing bag clamps 3 being made of stainless steel, the fixing bag clamps 3 being fixedly connected to the sealing bag body 2 by adhesive, the sealing bag body 2 being fixedly connected to the anchor cable by the fixing bag clamps 3, and a sealing ring disposed at the open end of the sealing bag body 2, the sealing ring being made of silicone.

[0027] During the grouting construction of anchor cables in miscellaneous fill layers, the sealing bag body 2 is first fitted onto the anchor cable and pushed to the predetermined sealing position in the borehole through appropriate operation to ensure that the sealing bag body 2 is in an accurate position. Then, the sealing bag body 2 is firmly fixed with the fixing bag clamp 3 to ensure that it does not shift during the grouting process. Next, the grouting operation begins. During grouting, the sealing bag body 2 begins to expand under the action of high-pressure grout. As the expansion process proceeds, the sealing bag body 2 tightly adheres to the borehole wall and the surface of the anchor cable, ensuring that there are no gaps between the sealing bag and the borehole wall. In this process, the sealing ring and sealant play an important role. The sealing ring effectively prevents grout leakage, and the sealant further enhances the sealing effect, ensuring that the grout flows only through the predetermined channel, thereby achieving an efficient and reliable grouting and sealing effect. Through this precise operation procedure, the entire grouting process not only improves construction efficiency but also ensures the quality and safety of anchor cable grouting and sealing.

[0028] Reference Figures 1-3 The inner layer of the sealed bag body 2 is provided with a corrosion-resistant rubber layer 201, the middle layer of the sealed bag body 2 is provided with a high-strength fiber reinforcement layer 202, and the outer layer of the sealed bag body 2 is provided with a wear-resistant rubber layer 203. The high-strength fiber reinforcement layer 202 is made of aramid fiber, which significantly improves the overall strength of the bag.

[0029] The sealed bag body 2 employs a multi-layered material structure design to ensure excellent durability and damage resistance in complex environments. The inner corrosion-resistant rubber layer 201 effectively prevents external corrosive substances from eroding the sealed bag body 2, extending its service life and avoiding performance degradation and material damage caused by corrosion. The middle high-strength fiber-reinforced layer 202 possesses excellent pressure-bearing capacity, effectively resisting external pressure and deformation stress, ensuring the bag is not easily deformed or ruptured under heavy loads, further enhancing the overall structural stability and reliability. The outer wear-resistant rubber layer 203 provides protection, effectively preventing damage to the sealed bag body 2 caused by friction or scratching during use, enhancing its wear resistance, and enabling it to maintain its performance for a longer period in various working environments. Through this multi-layered composite structure, the durability and damage resistance of the sealed bag are comprehensively improved.

[0030] Working principle: When grouting of anchor cables in miscellaneous fill layers is required, the sealing bag body 2 is first placed on the anchor cable, and then the sealing bag body 2 is pushed to the predetermined sealing position of the borehole. The sealing bag body 2 is fixed by the fixing bag clamp 3, and then the grouting operation is carried out. During the grouting process, the sealing bag body 2 expands under the action of high pressure grout, tightly adhering to the borehole wall and anchor cable. The inner corrosion-resistant rubber layer 201 prevents the sealing bag body 2 from being corroded, the middle high-strength fiber reinforced layer 202 withstands pressure and deformation stress, and the outer wear-resistant rubber layer 203 prevents the sealing bag body 2 from being scratched and damaged. The sealing ring and sealant ensure that the grout will not leak, thereby achieving efficient and reliable grouting and sealing effect.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
