Abstract

The invention relates to a method for filling sand in net bag, belonging to the technique that constructing tank in deep water. Wherein, said invention comprises sand bag, net bag and sling device; it is characterized in that: the size of sand bag is 2.8m*2.8m; the net bag is woven by nylon lines whose surface is coated by fishing net sheets and four angles are connected to slings; four slings are connected to three lifting rings, while two slings at one side are connected to one lifting ring, and another two slings are connected to two lifting rings; two lifting hooks are connected to two movable hooks; the loose hook of movable lifting hook is connected to the sling of another hook; when lifting the net bag, two lifting rings of net bag are suspended on the movable lifting hooks, and the mouth of movable lifting hook is closed, the lifting ring of two slings is suspended on another lifting hook, then using lifter to move the sand bag above the throw point, falling the movable lifting hook, to automatically release two lifting rings of movable lifting hook, utile the sand bag is fallen to the throw point.

Description

Technical field: [0001] The invention relates to a method for throwing and filling bagged sand for embankment construction in deep water. Background technique [0002] The bagged sand embankment core has good functions of retaining water and soil, and is widely used in hydraulic embankment construction. Firstly, sand bags need to be prepared for throwing and bagging sand. Currently, the huge sand bags used have a diameter of 4m and a length of 32m. The water gun is used to fill the bag with hydraulic sand, and the high-pressure water gun is used to quickly change the basically solid sand into fluid mud, and then use the mud pump to transport the mud to the pipeline, and finally open the pipeline valve, and insert the mud into the cuff of the bag body through the connecting pipe. Fill it into the bag, and after it is filled to a certain capacity, put the bag into the water, move the bag throwing boat to one side, and continue to fill the bag until the sand bag is completely ...

AI Technical Summary

Problems solved by technology

[0004] Rubble and sandbags are two different kinds of throwing objects. Because the net bag and throwing equipment of riprap are not suitable for the requirements of sandbag operation, when throwing sandbags, the bags will be stuck by slings or grids. Under the condition of uneven stress, the bag body is easily damaged and damaged. It has been proved by tests that the damage rate of the sand bag is as high as 2 / 3
