Horn-shaped side slope retaining structure of tunnel portal and construction method
The invention discloses a horn-shaped side slope retaining structure of a tunnel portal and a construction method. The retaining structure comprises flange piles, wherein the flange piles are arrangedon the inner side of a side slope and are distributed at intervals along the trend of the corresponding side slope; the flange parts of the flange piles are positioned on one side far away from the corresponding side slope; an L-shaped soil retaining plate is connected between two adjacent flange piles on the same side; two end parts of the soil retaining plate are correspondingly connected withthe flange parts of the corresponding flange piles; the height of the soil retaining plate is matched with that of the flange piles; and the height of the flange piles is matched with that of a side slope platform area. According to the structure, the soil pressure borne by the soil retaining plate can be effectively dispersed to two adjacent flange piles, the soil retaining plate and the flange piles are prevented from being staggered, the weak link of the traditional pile plate structure is eliminated, the stability of the retaining system is guaranteed, and the flange piles close to the endwall can be tightly attached to the end wall of the tunnel portal, so that the end wall is well protected, and the safety and reliability are effectively improved.
本发明公开了一种隧道洞口喇叭形边坡支挡结构及施工方法，支挡结构包含翼缘桩，所述翼缘桩设于边坡的内侧，所述翼缘桩沿对应所述边坡的走向间隔分布，所述翼缘桩的翼缘部位于远离对应所述边坡的一侧，同侧相邻两个所述翼缘桩之间连接有L型的挡土板，所述挡土板的两端部分别连接对应所述翼缘桩的翼缘部，所述挡土板的高度与翼缘桩的高度适配，所述翼缘桩的高度适配所述边坡平台区的高度。本结构能有效将所述挡土板受到的土压力分散给相邻两个所述翼缘桩，避免所述挡土板与翼缘桩发生错动，消除传统桩板结构的薄弱环节，保证支挡体系的稳定，并能使靠近端墙的翼缘桩能够与隧道洞门端墙紧密贴合，从而更好保护端墙，有效提升安全性和可靠性。
