Sinking construction device for bottom on-site construction upper 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 construction device of the building comprises a chain cutter excavating device, a hanging device, a pouring device and an assembly device, wherein the building comprises a bottom for on-site construction and an assembly type upper portion; the bottom is poured on the ground in a full-length mode through the pouring device, the upper portion is assembled above the bottom through the assembling device, the chain cutter excavating device comprises a chain cutter and a chain cutter driving device, the chain cutter comprises a chain and a cutter installed on the chain, and the chain cutter transversely or longitudinally wraps the outer side of the section of a building; when the building is in a suspended state through the hanging device, the chain cutter driving device is started, the chain cutter at the bottom of the building excavates rock soil, the chain cutter running from bottom to top brings the excavated rock soil to the upper portion, and sinking construction of the building is achieved.

Description

technical field [0001] The invention relates to the technical field of underground building construction, in particular to a sinking construction device used for on-site construction of an upper prefabricated underground building at the bottom. 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 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 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 easy to break; the descending speed is difficult to control; the bottom chain knife The cutting amount is out of control, and the cutting tool is very easy to be damaged; for this reason, we propose a sinking construction device for the bottom on-site construction of the upper prefabricated underground structure to solve the above problems
