It is connected as an entirety；
Cast-in-situ bored pile and longeron are connected as an entirety by cast-in-situ bored pile stake top along the longitudinally disposed longeron in tunnel.
For double track tunnel, cast-in-situ bored pile laterally sets four row, respectively positioned at left line solid concrete roabed plate both sides and right line
Solid concrete roabed plate both sides；
For single-track tunnel, cast-in-situ bored pile laterally sets two row, positioned at single line solid concrete roabed plate both sides.
Steel reinforcement cage built in cast-in-situ bored pile, framework of steel reinforcement built in longeron；
Steel reinforcement cage cage bar in cast-in-situ bored pile is together with the tie with reinforcing bar in longeron.
Longeron is along the elongated one-piece casting in tunnel axis direction.
The utility model has advantages below：
Tunnel Base composite consolidation technology provided by the utility model is by " stake+longeron " structure composition, and cast-in-situ bored pile
It is rigidly connected, inverted arch is filled, inverted arch and the following country rock of Tunnel Base link together with longeron, improves tunnel ballast bed structure
Integral rigidity, improve the overall mechanical properties of Tunnel Base structure, can effectively solve Tunnel Base structure protuberance, sedimentation becomes
The disease such as shape and horizontal displacement.
