Four-foot hollow block with concaved outer side faces of convex feet and construction method of four-foot hollow block

Abstract

A four-foot hollow block with concaved outer side faces of convex feet comprises a block body, wherein a ventilation hole is formed in the center position of the block body, the upper part and the lower port of the ventilation hole communicate with each other, the four sides of the block body are concaved, the four corners of the upper surface and the lower surface of the block body are respectively provided with one overhead convex foot, each convex foot is provided with an outer side face connected with an adjacent block body, the lower section of each outer side face is chamfered, and the upper section of each outer side face is a concaved section; and when the two adjacent four-foot hollow blocks are tightly connected, a protection gap used for preventing the convex feet from being crushed is formed between the concaved sections of the convex feet of the two four-foot hollow blocks. The invention provides a construction method of the four-foot hollow block with the concaved outer side faces of the convex feet. According to the four-foot hollow block with the concaved outer side faces of the convex feet and the construction method of the four-foot hollow block with the concavedouter side faces of the convex feet, the possibility of crushing of the convex feet is effectively reduced, and the service life is prolonged.

Description

technical field [0001] The invention relates to a four-legged hollow square, which is suitable for the field of wave-dissipating protection on slopes of hydraulic engineering, port engineering, and marine engineering, and is mainly used in water conservancy, port and shipping, marine and other industries in coastal areas. Or the improvement of the newly poured four-legged hollow square to avoid crushing of the protruding feet. Background technique [0002] The four-legged hollow square in the existing specification is prefabricated by concrete. There is a suspended protruding "foot" at the four corners of the upper and lower sides of the block, and the outer surface of each "foot" is vertical. On the surface, the central part of the block is a square, circular or other shaped hole, and the surrounding of the block is concave, so that there are holes between adjacent blocks after placement. As a slope wave-dissipating facility, the block structure has been widely used in wat...
