Concrete precast block for permafrost region slope protection, permafrost region slope protection structure and construction method of permafrost region slope protection structure
The invention relates to a concrete precast block for permafrost region slope protection, which comprises a first side plate, a second side plate and a top plate, and the first side plate and the second side plate are respectively integrated with the top plate to form the concrete precast block with a groove at the bottom. According to the concrete precast block for protecting the side slope in the permafrost region, when the concrete precast block is directly used for the side slope in the permafrost region, a through groove (ventilation duct) can be formed in the bottom of the concrete precast block through simple splicing, the through ventilation duct can also serve as a setting space of a condensation pipe, the surface of the side slope is cooled through the ventilation duct or the condensation pipe, and the side slope is protected. Before heat enters the roadbed, direct contact cooling is carried out on the surface of the slope, the frozen soil strength is enhanced, the method can also be used for slope treatment of an in-service roadbed, and therefore the purposes of improving the overall stability of the slope and the strength of a local fragile area of the slope are achieved.
本发明涉及一种多年冻土区边坡防护用混凝土预制块，包括第一侧板、第二侧板和顶板，且所述第一侧板和所述第二侧板分别与所述顶板一体成型为底部具有凹槽的混凝土预制块。本发明提供的冻土区边坡防护用混凝土预制块，当其直接用于多年冻土区的边坡时，通过简单的拼接便可在其底部形成贯通的凹槽(通风道)，贯通的通风道还可兼做冷凝管的设置空间，通过通风道或冷凝管对边坡表面进行降温，在热量未进入路基内部之前进行边坡表面直接接触降温，增强冻土强度，也可以用作在役路基的边坡处治，从而达到提高边坡整体稳定性及边坡局部脆弱区域强度的目的。
