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 necessa...

Embodiment Construction

[0022] In order to further understand the content of the invention, characteristics and effects of the present invention, the following examples are described in detail as follows:

[0023] See figure 2 , the present invention includes a top plate 5, a bottom plate 19 and a plurality of columns 8 between them, and each column 8 constitutes a middle frame with a rectangular cross section. In actual use, the middle frame is vertically inserted into the two vertical holes of the hollow block 20 , and the bottom end protrudes from the lower hole.

[0024] In this embodiment, the number of columns 8 is set to four, and the cross-section of the middle frame formed is rectangular. In terms of material, the column 8 can be made of angle steel, which can reduce the weight of the spreader itself while ensuring the overall structural strength. In order to facilitate vertical insertion of the hanger into the hole of the hollow block 20 , in this embodiment, the bottoms of the columns 8...

Abstract

The invention belongs to the technical field of the coastal reclamation and siltation promotion and in particular relates to a perforated block lifting appliance for the construction of a siltation promotion embankment. The perforated block lifting appliance comprises a top plate, a bottom plate and multiple stand columns arranged between the top plate and the bottom plate, wherein all the stand columns form a middle frame with a rectangular cross section, multiple lifting lugs are fixedly connected on the upper surface of the top plate, a vertical supporting plate is fixedly connected at the edge of one side of the upper surface of the top plate, a horizontal shaft sleeve is fixedly connected at the edge of the other side of the upper surface of the top plate, a lever is articulated at the top part of the supporting plate, the inner end of the lever is extended to the central line of the middle frame, the outer end of the lever is fixedly connected with a handle, and a pin is arranged in the shaft sleeve; a left overturning plate and a right overturning plate are articulated at the edges of the left side and the right side of the bottom plate respectively, and tension springs are both connected at the inner sides of the left overturning plate and the right overturning plate; the perforated block lifting appliance also comprises a sling, the top end of the sling is connected with the inner end of the lever, the bottom end of the sling is connected with the inner ends of two tension springs, a center hole is formed in the middle of the top plate, and the center hole penetrates through the middle-upper part of the sling and a lantern ring is arranged at the position of the middle-upper part of the sling.

Description

technical field [0001] The invention belongs to the technical field of silting promotion by sea reclamation, and in particular relates to a hollow block spreader for construction of siltation promoting dikes. 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 projects generally throw...
