Shallow-buried unsymmetrical-pressure tunnel portal slope protection structure
The embodiment of the invention provides a shallow-buried and bias-pressure tunnel portal slope protection structure, and relates to the field of shallow-buried and bias-pressure protection structures. The shallow-buried bias pressure tunnel portal slope protection structure comprises a first steel pipe and a second steel pipe which are inserted into one side of a formwork in a penetrating mode, the first steel pipe and one end of the first steel pipe are connected through threads, meanwhile, a feeding port is formed in one end of the second steel pipe in a penetrating mode, and a flow guide pipe and a first extension pipe are sequentially arranged on one side of an inner cavity of the feeding port; an inner cavity of the first steel pipe is of a hollow structure, a second extension pipe is arranged in the inner cavity of the first steel pipe, and the second extension pipe is connected with one end of the first extension pipe in a telescopic mode so that the second extension pipe can control and guide the slurry injection direction. Meanwhile, the second extension pipe and the first extension pipe which are arranged in the first steel pipe and the second steel pipe can guide the injection of the slurry, and the first discharge hole is prevented from being blocked through the telescopic block.
本申请实施例提供浅埋偏压隧道洞口边坡防护结构，涉及浅埋偏压防护结构领域。浅埋偏压隧道洞口边坡防护结构包括：模板一侧贯穿插入的第一钢管和第一钢管，第一钢管和第一钢管一端通过螺纹丝扣连接的第二钢管，同时在第二钢管的一端贯穿开设有进料口，且进料口的内腔一侧依次设置有导流管和第一延长管，第一钢管的内腔呈中空状结构，所述第一钢管的内腔设置有第二延长管，其第二延长管可伸缩式与第一延长管一端相连，使其控制导向浆液注入方向，在隧道洞口内部插入式设置有第一钢管与第二钢管，同时通过第一钢管与第二钢管内部设置的第二延长管和第一延长管即可导向其浆液的注入，并且通过可伸缩的伸缩块防止其第一出料孔出现堵塞。
