Description

Technical Field

[0001] The utility model relates to the field of mold bag concrete construction, in particular to an underwater mold bag concrete mold bag laying fixing device. Background Art

[0002] Bag concrete is made by pouring concrete or cement mortar into a bag with a high-pressure pump. The thickness of the concrete or cement mortar is controlled by the length of the rebar bag and the rebar rope (polymer such as nylon) inside the bag. After the concrete or cement mortar solidifies, it forms a plate-like structure or other structure with a certain strength to meet the needs of the project.

[0003] Geotextile bags have the following characteristics: 1. The construction is formed by one-time spraying, which is simple and fast; 2. It can adapt to various complex terrains, especially deep-water revetment and bottom protection, which do not require cofferdams and can be directly constructed underwater. It has a high degree of mechanization, a large slope area, strong integrity, good stability, and a long service life; 3. It has a certain degree of water permeability. After the concrete or cement mortar is poured in, the excess water seeps out through the gaps in the fabric, which can quickly reduce the water-cement ratio, accelerate the solidification speed of the concrete, and increase the compressive strength of the concrete. Due to its excellent performance and relatively economical cost, it has been widely promoted and applied in the mold bag revetment project.

[0004] When laying traditional mold bags, the upper edge is fastened with channel steel, which is connected to the steel pipe pile by a chain hoist. The bottom edge and both sides are fastened with sewn tie straps to fasten the steel pipe so that the mold bag can be fully stretched. A series of ropes are fastened to the steel pipe to ensure that the mold bag is stretched and slowly lowered to the slope along the edge of the ship. When laying the mold bag, it is laid from upstream to downstream, and sandbags are laid at the bottom to fix it. There is no device to fix the mold bag in the middle. When laying the mold bag, it floats due to the influence of water flow, and it is impossible to ensure that the mold bag is close to the slope surface, which is not conducive to the straightness of the slope line after the mold bag concrete is formed, nor is it conducive to the positioning and forming of the slope foot. It is easy to cause rework, affecting the construction period and construction quality. Summary of the invention
