Building block shaped like Chinese character 'qu', sinking mattress system of building blocks shaped like Chinese character 'qu' and construction method of sinking mattress system of building blocks shaped like Chinese character 'qu'

Abstract

The invention discloses a curved block, a curved block sinking system and a construction method thereof. The block includes a block body, and the block body is divided into upper and lower parts. The cross-section of the upper part A The shape is a trapezoidal structure, and the cross-sectional shape of the lower half B is a rectangular structure. There is a first through hole in the center of the block body, and a second through hole on one side of the first through hole. There are two third through holes on the other side, two first self-locking tenons are symmetrically arranged on the front side of the block main body, and two second self-locking tenons are arranged on the rear side of the block main body corresponding to the first self-locking tenons. A self-locking concave mortise, the left side of the main body of the block is provided with a second self-locking tenon, the right side of the main body of the block is provided with a second self-locking concave mortise, the upper half A of the main body of the block and the lower half There are two transverse reinforcement holes in the self-locking tenon at the intersection of part B. The process steps include making a solid row platform, laying geotextiles, arranging curved blocks, threading reinforcement, overall sinking and rowing, and solid rowing.

Description

technical field [0001] The invention discloses a zigzag block, a sinking and drainage system and a construction method using the zigzag block for protection of embankments of rivers, lakes and seas. Background technique [0002] As we all know, one of the most common reasons for the bank collapse of rivers, lakes and seas is the impact of water flow at the foot of the underwater bank slope. In order to stop this impact, ancient river control ancestors and modern water conservancy engineers have adopted sinking and drainage measures to protect the bottom . [0003] The sinking row generally needs to meet the following characteristics: 1) It has continuity, that is, the sinking row should extend from the water edge of the embankment to the underwater bank bottom; 2) It has firmness, that is, it has enough strength to resist the impact of the water flow; 3) It has a disguised form. Compatibility, i.e. being flexible enough to conform to the topography of the submerged slope bo...

Problems solved by technology

[0009] The object of the present invention is to provide a zigzagging block, zigzag block sinking and drainage system and construction method thereof. The sinking row formed after the block is assembled by a special construction method is used as a soft row for river bottom protection ( Slope) to meet the requirements of safety, environmental protection and ecological trinity of embankment engineering, overcome the poor durability of existing technology sinking and drainage, need frequent maintenance, sinking and discharging on the surface of the protected soil, does not have reverse filter function, sinking and discharging for a long time After the impact of water flow and tidal wave washing and suction, the protected soil particles are easily taken away by the water flow, which eventually leads to problems such as erosion and collapse
