Construction method for treating tunnel portal shallow-buried collapse slope accumulation body
The invention relates to a construction method for treating a tunnel portal shallow-buried collapse slope accumulation body. The construction method comprises the following steps of burying a plurality of steel pipe piles in a tunnel portal collapse accumulation body, and pouring cement paste under high pressure through the steel pipe piles so as to form a colloidal cement solidified body, so thatthe effects of reinforcing the shallow-buried collapse slope accumulation body and increasing skid resistance to prevent instability are achieved. The tunnel portal shallow-buried collapsed slope accumulation body is treated by grouting the steel pipe piles, a good effect is achieved on the reinforcement of the portal collapsed slope accumulation body, the tunnel construction safety is guaranteed, the construction efficiency is improved, and the construction cost is reduced. The construction method has the main obvious effects that after the steel pipe pile treatment is performed, a tunnel smoothly enters a hole, collapse and roof fall accidents do not occur to the tunnel in the area, and the back pressure retaining wall construction is not needed, so that the construction cost is furtherreduced.
本发明涉及一种隧道洞口浅埋崩坡积体处理施工方法，包括如下步骤：在隧道洞口崩塌堆积体处埋设多个钢管桩，通过钢管桩高压灌注水泥浆，形成胶状水泥固结体，达到加固浅埋崩坡积体、增大抗滑以防失稳作用。隧道洞口浅埋崩坡积体采用钢管桩注浆处理施工，在加固洞口崩坡积体中取得了良好效果，确保了隧道施工安全，提高了施工效率，降低施工成本。主要突出效果有：通过钢管桩处理后，隧道顺利进洞，且在此区域内隧道未发生坍塌及冒顶事故；无需反压挡墙施工，进一步节约造价。
