Tunnel portal section upward slope supporting method
The invention discloses a tunnel portal section upward slope supporting method, which belongs to the technical field of tunnel portal protection, and comprises the following steps of: arranging a first support on a tunnel upward slope section along the longitudinal direction; a second support connected with the first support is arranged on the upward slope section of the tunnel in the transverse direction; extending the open cut tunnel to cover the first support and the second support; the upper portion of the extended part of the open cut tunnel is backfilled with sandy soil, and the first support and the second support are covered; according to the side slope protection structure, a first support and a second support are combined with tunnel open cut tunnel extension and backfill back pressure to conduct comprehensive support, after grouting is completed, the first support, the second support and concrete form an integrated structure, the side slope stability can be effectively improved, and the tunnel entering construction safety is guaranteed; the influence of slope disasters such as rockfall can be reduced by extending the open cut tunnel and combining sand backfilling back pressure, and the first support and the second support are protected to a certain extent.
本发明公开了一种隧道洞口段仰坡支护方法，属于隧道洞口防护技术领域,包括：沿着纵向方向，对隧道仰坡段设置第一支护；沿着横向方向，对隧道仰坡段设置与第一支护连接的第二支护；延长明洞，使其覆盖第一支护和第二支护；在明洞延长部分上部回填砂土，将所述第一支护和第二支护覆盖；通过设置的边坡防护结构，采用第一支护和第二支护结合隧道明洞延长和回填反压进行综合支护，注浆完成后第一支护和第二支护和混凝土形成一体结构，能有效的提高边坡稳定性，保证进洞施工安全；明洞延长并结合砂土回填反压能够减少落石等边坡灾害的影响，并对第一支护和第二支护进行一定的保护作用。
