求翻译：支撑护壁采用外齿式混凝土护壁，该种形式的护壁，其抗塌孔的性能好，又便于人工用钢钎捣实混凝土，增大了桩的摩擦阻力。是什么意思？

Wall support with external gear concrete protective wall, which forms the Wall, the collapse of its anti-hole performance, and easy to use drill rod tamping concrete labor, increasing the frictional resistance of the pile.

In tooth-supporting care wall concrete wall, the form of care wall collapsed holes of the resistance, its good performance, it is easy to artificial steel brazing & smashed, and increased real concrete piles of friction resistance.

The support counterfort uses the external tooth type concrete counterfort, this form counterfort, its anti-collapses the hole performance to be good, also is advantageous for artificially with the drill rod compressed concrete, has increased the pile friction drag.

Supporting wall protection by outer gear concrete retaining walls, in the form of wall protection, anti-hole collapse of its good performance and ease of drill Rod ramming concrete for artificial, increases the frictional resistance of piles.

Wall support with external gear concrete protective wall, which forms the Wall, the collapse of its anti-hole performance, and easy to use drill rod tamping concrete labor, increasing the frictional resistance of the pile.
