Molding die and molding method for deposition promotion dyke hollow block

Abstract

The invention belongs to the technical field of sea enclosing deposition promotion, in particular to a molding die and a molding method for a deposition promotion dyke hollow block. The molding die comprises a vertical core die (6) positioned in the center and having a rectangular cross section and a first side plate (2), a second side plate (5), a third side plate (8) and a four side plate (9) which are positioned around the vertical core die (6); the four side plates define a frame with a rectangular cross section, and every two adjacent side plates are fixedly connected at a jointed edge; rectangular drawer holes (3) are formed in centers of the first side plate (2), the second side plate (5), the third side plate (8) and the four side plate (9); the molding die also comprises four drawer type core dies (4) which are transversely inserted into the inner cavity of the frame from the drawer holes (3) of all side plates and have rectangular sections; after complete insertion, the inner end surface of each drawer type core die (4) is abutted against the middle of the corresponding outer wall of the vertical core die (6) respectively. The invention also relates to a method which adopts the molding die to mold a hollow block.

Description

technical field [0001] The invention belongs to the technical field of silting promotion by sea reclamation, and in particular relates to a forming mold and a forming method of a hollow block for silting promoting embankment. Background technique [0002] Sea reclamation is an effective way to solve the contradiction of land resource shortage in coastal areas. With the dwindling of high beach resources and the increasing engineering experience, sea reclamation projects are gradually developing from tidal flat areas to shallow sea areas. Before land reclamation construction in shallow sea areas, the silt-promoting project is generally carried out first. The silt-promoting project can accelerate the sedimentation effect of the sediment. The silt-promoting dike project can reduce project investment and reduce project risks. Therefore, the silt-promoting dike project has become a sea reclamation project One of the keys to geoengineering. [0003] Existing silt-promoting project...

AI Technical Summary

Problems solved by technology

There are relatively obvious defects in the above-mentioned silting promotion projects: a large amount of rocks are required in the construction of the project, and the amount of throwing is huge, so that in areas where the supply of rocks is tight, there will be a problem of increased construction costs due to the difficulty in obtaining construction materials; After the block stones are thrown, the silt-promoting embankment formed by it has a low porosity and a large self-weight. In this way, in the construction of silt-promoting soft soil foundation, because the block stone silt-promoting embankment has potential compressive damage to the foundation, so before construction It is necessary to carry out high-level pretreatment on the soft soil foundation, resulting in an increase in project investment; the individual volume and weight of the block stones are small, and the shape is irregular. The surface that is subjected to the erosion of waves needs to be equipped with a wind and wave protection structure to avoid damage to the embankment caused by long-term wind and wave erosion, which undoubtedly increases the complexity of construction and the cost of the project
