Sinking construction device for assembly type underground building

Abstract

The invention discloses a sinking construction device for a bottom on-site construction upper assembly type underground building and relates to the technical field of underground building construction. The underground building comprises an outer wall, a top plate, a bottom plate and a construction device and is composed of end sections located at two ends and a middle section located in the middle, and the outer wall comprises a longitudinal wall and a transverse wall; the end section comprises a transverse wall located at an end and two longitudinal walls located on the two sides, and the middle section comprises longitudinal walls located on the two sides; the construction device comprises an excavating device, a hanging device and an assembling device, the hanging device and the assembling device are located at the top of a building, the excavating device excavates rock soil at the bottom of a bottom plate, a longitudinal wall comprises holes which are located above the bottom plate and staggered up and down, a chain cutter wraps the bottom plate through the holes, the longitudinal wall comprises a lower longitudinal wall located below the holes and an upper longitudinal wall located above the holes, and a driving device starts; the chain cutter at the bottom of the bottom plate excavates rock soil, the chain cutter running from bottom to top brings the excavated rock soil to the upper portion, sinking operation of the building is achieved, and the building sinks to the set depth.

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. Correction device, and once deviation occurs, it is difficul...

[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
