Four-foot hollow square block with inclined side walls and construction method thereof

Abstract

The four-foot hollow square block with the inclined side walls comprises a block body, the center of the block body is provided with a vent hole which is communicated up and down, the four side walls of the block body are concave from the upper and lower surfaces of the block body, the four corners of the upper and lower surfaces of the block body are respectively provided with a suspended convex foot. The side wall of the protruding part of at least one edge of the periphery of the block body is a backward or forward inclined face or a curved face comprising the inclined face and obliquely intersects with the upper face and the lower face of the block body, and when every two adjacent four-foot hollow square blocks are connected, the inclined faces of the opposite side walls of the two four-foot hollow square blocks incline in the same direction. Therefore, when the four-foot hollow square block moves towards any direction above the block body, the four-foot hollow square block is blocked by other four-foot hollow square blocks on the periphery. The invention further provides a construction method of the four-foot hollow square block with the inclined side walls. According to the four-foot hollow square block with the inclined side walls and the construction method of the four-foot hollow square block, the embedding and clamping force between block bodies of the four-foot hollow square block is effectively increased, the anti-jumping capacity of the block bodies is improved, and extrusion and breakage of convex feet are effectively reduced.

Description

Technical field [0001] The present invention relates to a four-foot hollow square, suitable for watermakers, Hong Kong workers, and sea industries, mainly used in coastal area water conservancy, portal, ocean and other industrial dams, surrendy slope has been built. Or improvements in the newly poured four-foot hollow squares, avoiding the flushing, blocking, and improving the resistance of the block. Background technique [0002] The four-foot hollow square in the existing specification is prefabricated, and the four angles in the top of the block have a floating "foot", and the outer side of each "foot" is vertical. The center portion of the block is square, circular, and the like aperture, the block is concave in the four-week side of the side, so that there are holes between adjacent blocks after placing, and the four-week side wall of the block is perpendicular to the upper and lower surfaces of the block. . As a slope, the structure has been generally applied to water conse...

Problems solved by technology

As a slope wave-dissipating facility, the block structure has been widely used in water conservancy, port waterway, ocean and other industries, and relevant industry standards have stipulated the design of its structural size; The outer walls of the blocks are uniformly perpendicular to the upper and lower sides of the block. When encountering a sufficiently large external force such as a wave force perpendicular to the upper and lower sides of the block, the block will jump out and become unstable, which will reduce the wave dissipation protection ability of the block. , affect the safety of project operation

[0003] For the "four-legged hollow cubes" designed according to the existing codes on the coastal dykes, the conventional method of improving the fortification standard in the engineering field is to remove all the four-legged hollow cubes on the slope and redesign a heavier four-legged hollow cube. Hollow squares with feet or other special-shaped blocks with stronger wind and wave resistance, the original four-legged hollow squares are no longer used, not only waste of resources, but also high project cost
