Background
The revetment engineering revetment block selects the four-foot hollow block, has the advantages of tidiness, attractive appearance, strong wave impact resistance and the like, but has high installation precision and high difficulty, and particularly in the installation process of the curve section four-foot hollow block, the installation quality of the four-foot hollow block is ensured to meet the requirement on the width of gaps among blocks in the wave breaker design and construction specification (JTS 154-1-2011), and the blocks at the slope bottom, the slope surface and the slope top of the same section are ensured to be positioned on the same axis so as to ensure the stability of block installation.
When the four-foot hollow blocks in the revetment engineering curve section are installed, the blocks at the slope bottom, the slope surface and the slope top are positioned on curves with different radiuses, and the blocks at the slope bottom, the slope surface and the slope top are positioned at the same axis, and the blocks at the slope bottom provide support for the blocks at the slope surface and the slope top.
The first conventional technology comprises the following steps: gaps among blocks positioned at the curve with the minimum radius are controlled according to 2cm, blocks at the slope bottom, the slope surface and the slope top are positioned on the same axis, the gaps among the blocks are increased along with the increase of the radius of the curve where the blocks are positioned, and after the four-foot hollow block is installed, the gaps among the blocks are filled with broken stones.
The defects and shortcomings exist: by adopting the conventional technology I, the gaps among the four-foot hollow blocks can not meet the requirements of ' the adjacent height difference of the four-foot hollow blocks is not more than 150mm and the maximum width of the joints is not more than 100mm ' specified in No. 7.3.6 of breakwater design and construction Specifications '. And the broken stones filled in the four-foot hollow block are easy to be washed away by waves, so that the stability of the block after being installed and the durability of the bank protection project are influenced.
And a second conventional technology: after the four-foot hollow blocks on the same radius curve are installed, gaps among the blocks are controlled according to item 7.3.6 of breakwater design and construction Specification, namely the maximum width of the gaps among the blocks is less than 100mm, but the four-foot hollow blocks at the slope bottom, the slope surface and the slope top of the same section are not positioned on the same axis.
The defects and shortcomings exist: by adopting the second conventional technology, the four-leg hollow block is in a structure form that the peripheral edge is inwards concave, as shown in the attached figure 2. If the blocks at the bottom of the slope, the slope and the top of the slope are not on the same axis, the block at the lower part cannot provide enough supporting force for the block at the upper part, and the stability of the installed blocks and the durability of the revetment engineering are influenced. And adopt the hollow block of four feet after the installation of conventional technology two, lost the hollow block of four feet and regarded as the neat pleasing to the eye advantage of armor block, violated the design original intention.
Summarizing the problems, the method can be known that when the space curved surface is paved by adopting the four-corner hollow block, a larger gap is generated, and the gap can not resist the scouring of sea waves if being filled with broken stones, so that a new method for paving the four-foot hollow block of the curve section of the bank protection engineering is urgently needed.
