Sinking construction device for fabricated underground building

Abstract

The invention discloses a sinking construction device for a fabricated underground building, and relates to the technical field of underground building construction. The building comprises an outer wall, a top plate, a bottom plate and a construction device. The construction device comprises an assembling device, an excavating device and a hanging device located at the top of the building; the excavating device comprises an outer wall excavating device and a bottom plate excavating device; the outer wall excavating device and the bottom plate excavating device comprise chain cutter excavating devices, and each chain cutter excavating device comprises a chain cutter and a driving device; the chain cutters comprise outer wall chain cutters in the outer wall excavating device and bottom plate chain cutters in the bottom plate excavating device; each driving device comprises an outer wall driving device and a bottom plate driving device, the outer wall driving devices are mounted above the outer wall, the outer wall chain cutters envelope the outer wall from the top of a sinking part of the building, and the bottom plate chain cutters envelope the bottom plate; and a longitudinal wall comprises upper holes and lower holes, the upper holes are vertically staggered, the lower holes are vertically staggered, the upper holes are formed above the bottom plate, the lower holes are next to the lower part of the bottom plate, and the bottom plate chain cutters envelop the bottom plate through the upper holes and the lower holes.

Description

technical field [0001] The invention relates to the technical field of underground building construction, in particular to a sinking construction device for an assembled underground building. Background technique [0002] Existing large-scale underground buildings are usually constructed by the open-cut method. The open-cut method needs to excavate the foundation pit first for support, and then pour or assemble the underground building in the foundation pit. Temporary support and dewatering of the foundation pit are required. The construction period is long and the cost is high; At present, chain cutters are used to excavate the bottom rock and soil, and the technical scheme of overall sinking, and the sinking construction without hanging devices, because the load of the underground building itself is too heavy, has the following defects: it is easy to produce tilt and offset, and it needs to be added when sinking.

[0002] Existing large-scale underground buildings are usually constructed by the open-cut method. The open-cut method needs to excavate the foundation pit first for support, and then pour or assemble the underground building in the foundation pit. Temporary support and dewatering of the foundation pit are required. The construction period is long and the cost is high; At present, chain cutters are used to excavate the rock and soil at the bottom, and the technical scheme of overall sinking, and the sinking construction without hanging devices, because the load of the underground structure itself is too heavy, has the following defects: it is easy to produce inclination and deviation, and additional installations are required when sinking. The deviation correction device, and once deviation occurs, it is difficult to achieve deviation correction; such a large load is pressed on the bottom chain knife, resulting in too much power of the drive device, and the chain knife is easily broken; the descending speed is difficult to control; the bottom chain knife The amount of feed is out of control, and the tool is easily damaged
