Description

Technical Field

[0001] The utility model belongs to the field of coastal solidification construction, and specifically relates to a reef sand mold bag filling device. Background Art

[0002] With the continuous expansion of my country's infrastructure, continuous innovation in science and technology, the emergence of new technologies, and the diversification of construction market types, some projects are constructed in coastal areas. Due to limited site conditions, temporary construction projects of all sizes need to be arranged near the coastline. There are no permanent revetments, wave walls and other protective facilities in the temporary construction areas.

[0003] Traditional revetments are reinforced concrete retaining walls. The foundation construction is affected by tides and requires long-term drainage. The construction is difficult, time-consuming and costly. At the same time, anti-corrosion steel bars and concrete are required to increase the service life of the concrete retaining walls. The engineering traces are obvious and will cause ecological pollution to the surrounding sea areas. Therefore, the reef sand mold bag wave-breaking wall revetment was born. The mold bags are filled with sand and gravel. The natural sand and gravel can blend with nature without pollution.

[0004] For example, the Chinese invention patent with the authorization publication number CN105256817B discloses a construction method for underwater filling of large mold bags, which adopts the following steps: 1. The corner points of the mold bag are laid out and fixed; 2. Positioning piles are set, and the diagonal points and the edge lines are encrypted and fixed with steel pipes; 3. The mold bag is processed and made, and a double-layer cuff is sewn, and a positioning buoy is sewn on the top of the mold bag; 4. The mold bag is laid on the water, and the mold bag folded by the folding fan method is laid on the water surface, and the edges and corners are fixed on the positioning piles with wire rings; 5. The water-sand mixture is processed in the cabin of a suction dredger or a sand transport ship, and it is pumped into the bag body through a pipeline with a mud pump, and the bag mouth is connected to the bag elbow with an easy-to-detach clamp to easily change the filling direction; 6. The mold bag is horizontally overlapped and vertically layered and staggered to form a weir body. The present invention simplifies the number of pipe transfers during the filling process, overcomes the problems of uneven filling and difficult to control the underwater filling thickness, loose cuff tying and easy to burst, and improves the working efficiency of underwater filling mold bags.

[0005] However, in actual use, it is necessary to manually step on the filled mold bag to promote the discharge of water in the bag, and at the same time smooth the surface of the mold bag to prevent the occurrence of uneven height. The operation is cumbersome, and in some specific cases, underwater operation is required, which requires divers to operate repeatedly. It is inconvenient to use and reduces the operating efficiency. At the same time, most of the joints of sand and gravel require multiple fixing devices to connect. Since the conveyed material is sand and gravel, it is easy for sand and gravel to enter the connection, resulting in unstable connection. Utility Model Content
