Abstract

The invention relates to a short canal and a short canal sand consolidation agent reinforcing construction technique. The short canal includes a steel pipe; the body of the steel pipe is provided with a plurality of holes; one end of the steel pipe is provided with a pyrometric cone; the cone part is provided with a cotton yarn. The short canal sand consolidation agent reinforcing construction technique includes inserting and beating the short canal as well as locating the short canal; grouting and closing a tunnel face; grouting construction on the tunnel face. The technique solves the problem of large pollution to the underground water and not good rock surrounding and reinforcing effects during the consturction process and has the characteristics of less pollutoin to the underground water, good rock surrounding and reinforcing effects, being not restrained by time, being simply and easily operated, low cost, high safety factor, and the like. The short canal and a short canal sand consolidation agent reinforcing construction technique can be broadly applied to the tunnel construction of underground cutting with shallow overburden of a water-enriched sandy stratum.

Description

Technical field

[0001] The invention relates to a short conduit and a short conduit sand-consolidating agent reinforcement construction technology in the technical field of underground excavation tunnel construction. Background technique

[0002] In the construction of modern underground excavation tunnels, with the advancement of science and technology, operators' awareness of personal safety, environmental protection, and energy conservation is increasing day by day. Due to the advantages of no noise during construction, no change to the surface environment, no interruption of ground economic activities, short construction period and low cost, underground excavation tunnels are widely used in tunnel construction. When this technology is used for construction in V-type surrounding rock (sand layer), the surrounding rock of the underground excavation tunnel is firstly pre-reinforced with small conduit grouting in advance. What effective measures to take to realize the advan...
