Inverted arch synchronous backfilling device for tunnel construction

Abstract

The invention relates to the technical field of construction equipment, and discloses an inverted arch synchronous backfilling device for tunnel construction. The inverted arch synchronous backfilling device comprises an outer bracket, a fixed pile is arranged at the left end of the outer bracket, a traction piece is movably connected to the left side of the fixed pile, an auxiliary seat is arranged in the middle of the outer bracket, a filling opening is fixedly connected to the upper end of the left side of the auxiliary seat, a filling truck is arranged at the position, under the auxiliary seat, of the outer bracket, a chain groove is formed in the outer side of the filling truck, and a driving shaft is arranged at the upper end of the left side of the filling truck. According to the inverted arch synchronous backfilling device for tunnel construction, filling materials are firstly smashed through a stirring shaft, then are filled into empty grooves in the surface of the chain groove and are filled into an inverted arch along the obliquely-downward filling truck, so that the situation that the filling materials directly impact the inverted arch to cause sediment splashing can be avoided, and material waste is prevented; and meanwhile, the construction risk can be reduced, the landing speed of the filling materials is reduced, material gaps formed during filling can be effectively controlled, and convenience is provided for follow-up flattening.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to an inverted arch synchronous backfill device for tunnel construction. Background technique [0002] The inverted arch produced during the construction process of shield tunnels and other tunnels is one of the main components of the tunnel structure. Due to the design and construction of the inverted arch structure of the tunnel, the tunnel structure is unstable, the road surface is subsidence and cracked, and mud is poured out. There are many examples. For this reason, the inverted arch structure must be carefully constructed, and the backfill of the inverted arch is gradually replaced by new materials to replace traditional concrete backfill, so as to ensure the quality of the tunnel. However, limited by the tunnel space, most of the existing backfilling still relies on manual work, which is time-consuming, laborious, and inefficient. After backfilling, operation...

Problems solved by technology

However, limited by the tunnel space, most of the existing backfilling still relies on manual work, which is time-consuming, laborious, and inefficient. After backfilling, operations such as compaction and leveling are required, which increases the workload.
