Inverted arch synchronous backfilling device for tunnel construction
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.
本发明涉及施工设备技术领域，且公开了一种隧道施工用仰拱同步回填装置，包括外支架，所述外支架的左端设置有固定桩，所述固定桩的左侧活动连接有牵引件，所述外支架的中部设置有辅座，所述辅座的左侧上端固定连接有填筑口，所述外支架位于辅座的正下方设置有填筑车，所述填筑车的外侧设置有链槽，所述填筑车的左侧上端设置有驱动轴。该隧道施工用仰拱同步回填装置，填筑材料会先经过搅拌轴粉碎后填进链槽表面空槽，沿着斜向下的填筑车填入仰拱，这样可以避免填筑材料直接冲击仰拱造成泥沙飞溅，防止材料浪费的同时，可以降低施工风险，而且降低填筑材料的落地速度，可以有效控制填筑时形成的材料间隙，给后续压平提供方便。
