Description

Technical Field

[0001] This utility model relates to the field of molded bag technology, and in particular to a hinged bottom protective molded bag. Background Technology

[0002] Bottom protection bags are large-area continuous bagged materials made of geotextiles. Concrete or cement mortar is filled into the bags using a high-pressure pump, and after solidification, they form an integral concrete slab. After solidification, they form a plate-like structure or other structure with a certain strength, used to protect riverbeds, dam foundations, and other parts that are susceptible to water erosion.

[0003] Current bottom protection bags mainly rely on their own weight and the density of the filling material to maintain stability. If they are subjected to strong water flow, they may slide or even shift due to insufficient friction at the bottom or the impact force being greater than their own weight. Therefore, in order to solve the above defects, the inventors propose a hinged bottom protection bag. Utility Model Content

[0004] The main purpose of this utility model is to provide a hinged bottom protection mold bag, which can effectively solve the problem of slippage or even displacement of the bottom protection mold bag in the prior art due to insufficient bottom friction or impact force greater than its own weight.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A hinged bottom protection bag includes a bag body and a nylon rope. Multiple connecting fabrics are fixedly installed on the outer bottom surface of the bag body, and an outer tube is fixedly installed on the bottom surface of the connecting fabrics. An inner rod is slidably connected inside the outer tube. A fixing hole is opened on one side of the outer surface of the outer tube, and multiple adjustment holes are opened at equal intervals on one side of the outer surface of the inner rod. Two mounting holes are opened on both the left and right sides of the outer top surface of the bag body.

[0007] Preferably, a spring is fixedly installed inside the adjustment hole, a baffle is fixedly installed at one end of the spring, and a silicone ring is fixedly installed on the side of the baffle.

[0008] Preferably, a sealing ring is embedded on one side of the inner side of the outer tube, a protective ring is fixedly installed on the outer surface of the outer tube on the side of the fixing hole, and a sealing ring is fixedly installed on the inner wall of the protective ring.

[0009] Preferably, two connecting holes are opened on the left side of the outer surface of the bag body, and a guide sleeve is fixedly installed inside each of the two connecting holes. A magnet is fixedly installed inside the guide sleeve. Two guide rods are fixedly installed on the right side of the outer surface of the bag body, and an iron plate is fixedly installed at the end of the two guide rods away from the bag body.

[0010] Preferably, the top surface of the bag has multiple filling openings, and multiple sealing cloths are fixedly connected to the outer surface of the bag on one side of the filling openings.

[0011] Preferably, the bag body includes an inner layer, an intermediate layer is fixedly installed on the outer surface of the inner layer, and an outer layer is fixedly installed on the side of the intermediate layer away from the inner layer.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This utility model discloses a hinged bottom-protecting molded bag. By setting an outer tube, during actual operation, when laying the bag, the inner rod is manually pulled to move inside the outer tube, thereby adjusting the length of the inner rod extending outside the outer tube. After adjustment, the bolt is inserted through the protective ring and rotated into the overlapping fixing hole and adjustment hole. The bolt will push the baffle to compress the spring, thus completing the bolt installation and fixing the adjusted inner rod. This allows the bag to be inserted into the laying position. Therefore, when the bag is subjected to strong water flow impact, it can effectively prevent slippage or even displacement due to insufficient bottom friction or water flow impact force exceeding its own weight, thereby improving the stability of the bag.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] This utility model discloses a hinged bottom protective mold bag, such as Figure 1-10 As shown, the bag includes a bag body 1 and a nylon rope 3. Multiple connecting fabrics 401 are fixedly installed on the outer bottom surface of the bag body 1. The connecting plate is fixedly connected to the outer layer 1031 of the outer bottom surface of the bag body 1 by sewing.

[0027] Furthermore, an outer tube 4 is fixedly installed on the bottom surface of the connecting cloth 401, and an inner rod 406 is slidably connected inside the outer tube 4. The inner wall of the outer tube 4 and the outer wall of the inner rod 406 are sandblasted to increase the surface roughness, making it difficult for mud and sand to adhere. In addition, the surfaces of the outer tube 4 and the inner rod 406 are coated with a nano-level silica coating. By utilizing the hydrophobicity of the nanoparticles, the adhesion between mud and sand and metal is further reduced.

[0028] The inner rod 406 can move inside the outer tube 4, thereby adjusting the length of the portion of the inner rod 406 extending outside the outer tube 4 to adapt to the burial depth requirements of different geological conditions.

[0029] A fixing hole 403 is provided on one side of the outer surface of the outer tube 4. The inner wall of the fixing hole 403 is threaded so as to be threaded to the external bolt. A plurality of adjusting holes 4061 are provided at equal intervals on one side of the outer surface of the inner rod 406. The size of the adjusting holes 4061 is the same as the size of the fixing holes 403. When the inner rod 406 moves inside the outer tube 4, the plurality of adjusting holes 4061 will coincide with the fixing holes 403 in sequence. The external bolt is inserted into the overlapping fixing holes 403 and adjusting holes 4061 to fix the adjusted inner rod 406. Two mounting holes 2 are provided on the left and right sides of the outer top surface of the bag body 1.

[0030] After the bag 1 is filled, pass one end of the nylon rope 3 through the mounting hole 2 of the first bag 1, pull the nylon rope 3 towards the adjacent bag 1, pass it through the corresponding mounting hole 2 of the second bag 1, adjust the distance between the two bags to the design value, and then tie knots at both ends of the nylon rope 3 to fix it. Use a double overhand knot or a fisherman's knot to fix it, and the two bags 1 can be hinged together by the nylon rope 3. In this way, multiple bags 1 can be hinged together by the nylon rope 3.

[0031] A spring 4062 is fixedly installed inside the adjusting hole 4061. A baffle 4063 is fixedly installed at one end of the spring 4062, and a silicone ring 4064 is fixedly installed on the side of the baffle 4063. When the external bolt is inserted into the adjusting hole 4061, it will push the baffle 4063 to move, causing it to squeeze the spring 4062. However, since the threaded connection between the bolt and the fixing hole 403 has self-locking properties, the squeezed spring 4062 cannot push the baffle 4063 to reset.

[0032] Under normal conditions, the baffle 4063 will block the opening of the adjustment hole 4061, and the silicone ring 4064 will contact the inner wall of the adjustment hole 4061. When the inner rod 406 extends to the outside of the outer tube 4 and is inserted into the geological environment, it can effectively prevent soil from entering the adjustment hole 4061.

[0033] A sealing ring 402 is embedded on one side of the inner tube 4. The sealing ring 402 is made of fluororubber, which can increase the sealing between the outer tube 4 and the inner rod 406. A protective ring 404 is fixedly installed on the outer surface of the outer tube 4 on one side of the fixing hole 403. A sealing ring 405 is fixedly installed on the inner wall of the protective ring 404. The sealing ring 405 is also made of fluororubber. The external bolt can be inserted into the protective ring 404 and pass through the protective ring 404 to be inserted into the overlapping fixing hole 403 and adjusting hole 4061.

[0034] The sealing ring 405 on the inner wall of the protective ring 404 can effectively prevent mud and sand from entering the gap between the bolt and the fixing hole 403.

[0035] Two connecting holes 101 are opened on the left side of the outer surface of the bag body 1, and guide sleeves 102 are fixedly installed inside the two connecting holes 101. Magnets 103 are fixedly installed inside the guide sleeves 102. Two guide rods 1021 are fixedly installed on the right side of the outer surface of the bag body 1, and iron pieces 1022 are fixedly installed at the ends of the two guide rods 1021 away from the bag body 1. When the guide rods 1021 move to the accessory of the guide sleeves 102, the magnets 103 will attract the iron pieces 1022, thereby allowing the guide rods 1021 to be inserted into the guide sleeves 102, so that the bags 1 can be quickly aligned when multiple bags 1 are connected to each other.

[0036] The top surface of the bag body 1 has multiple filling ports 104. Mortar can be injected into the interior of the bag body 1 through the filling ports 104. Multiple sealing cloths 105 are fixedly connected to the outer surface of the bag body 1 on one side of the filling ports 104. After the mortar is injected, the sealing cloths 105 can be sewn to the bag body 1 to cover the filling ports 104.

[0037] The bag body 1 is made of two layers of fabric, which are stitched together in a cross shape to form an initial block structure. High-strength warp threads are horizontally embedded in the middle layer of the double fabric. The high-strength warp threads are made of polyester fiber and serve as reinforcement in the thickness direction. Their function is to constrain the expansion of the mold bag when filling mortar, ensure that the block height is uniform and controllable, and avoid the mold bag from being excessively bulging or deformed due to mortar pressure.

[0038] The upper and lower fabrics include an inner layer 1033, an intermediate layer 1032 fixedly installed on the outer surface of the inner layer 1033, and an outer layer 1031 fixedly installed on the side of the intermediate layer 1032 away from the inner layer 1033. The outer layer 1031 is made of aramid fiber woven geotextile with a polyurethane coating to improve puncture resistance and aging resistance. The intermediate layer 1032 is made of polypropylene woven geotextile and is bonded to the outer layer 1031 by hot pressing to form a composite base. The inner layer 1033 is made of short fiber needle-punched nonwoven geotextile with a rough surface to enhance the adhesion to the filling mortar.

[0039] The working principle of this utility model is as follows: After the staff transports the bag 1 to the designated location, they use a high-pressure pump to fill the mortar into the inside of the bag 1 through the filling port 104. After filling, the sealing cloth 105 is installed on the outer surface of the bag 1 by sewing to seal the filling port 104.

[0040] After the bag 1 is filled, pass one end of the nylon rope 3 through the mounting hole 2 of the first bag 1, pull the nylon rope 3 towards the adjacent bag 1, pass it through the corresponding mounting hole 2 of the second bag 1, adjust the distance between the two bags to the design value, and then tie knots at both ends of the nylon rope 3 to fix it. Use a double overhand knot or a fisherman's knot to fix it, and the two bags 1 can be hinged together by the nylon rope 3. In this way, multiple bags 1 can be hinged together by the nylon rope 3.

[0041] Then, depending on the actual situation, manually pull the inner rod 406 to move it inside the outer tube 4 to adjust the length of the inner rod 406 extending to the outside of the outer tube 4. After adjustment, insert the bolt through the protective ring 404 and rotate it into the overlapping fixing hole 403 and adjustment hole 4061. The bolt will push the baffle 4063 to compress the spring 4062, thus completing the bolt installation and fixing the adjusted inner rod 406. Then, insert it into the position where the bag body 1 is laid.

[0042] All of the above-mentioned components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0043] The specific models and specifications of the bolts, nylon ropes 3, and magnets 103 proposed in this application need to be selected and determined according to the actual specifications of the device. The specific selection calculation method, circuit connection method and control method all adopt the existing technology in this field, and the power supply is also common knowledge in this field, so it will not be described in detail.
