Abstract

The invention relates to a tunnel construction technology, aims at solving the problem that an existing structure and construction method cannot well achieve bearing of the colluvial clay and provides a colluvial clay tunnel pipe shed structure and a colluvial clay tunnel construction method. The colluvial clay tunnel pipe shed structure comprises a guide wall, guide tube main bodies and connection bodies. The guide wall is provided with multiple guide holes, the guide tubes correspond to all the guide holes respectively, one end of each guide tube is inserted into the colluvial clay, and the other end of each guide tube is fixedly connected to the guide wall. Multiple grouting openings are formed in the peripheries of the guide tubes, so that grouting into the colluvial clay is achieved. Two rows of cylindrical ground surface grouting bodies are arranged outside the colluvial clay, and cylindrical in-cave grouting bodies which are distributed in a radial pattern are arranged on the bottom of the colluvial clay, so that the colluvial clay is prevented from collapsing, and the construction safety is ensured. The colluvial clay tunnel pipe shed structure and the colluvial clay tunnel construction method have the advantages that the structure has high bearing capacity and can achieve effective bearing for upper broken slope accumulation.

Description

technical field [0001] The invention relates to a tunnel construction technology, in particular to a pipe shed structure of a collapsing body tunnel and a construction method for a collapsing body tunnel. Background technique [0002] With the rapid development of my country's expressway industry, the scope of its construction has also expanded, and the expressway has gradually extended to mountainous areas. Due to the particularity and complexity of the geological structure of mountainous areas, the number of expressway tunnels in mountainous areas has continued to increase. Different terrain and geological conditions will be encountered during the construction process, among which the tunnel entry and exit construction under complex terrain conditions is highly technical. Especially when the soil at the entrance of the tunnel is a collapsing mass, the load-bearing requirements for the soil are higher. [0003] The existing structure and construction method can not realize...
