Sinking construction device for cast-in-place underground building

Abstract

The invention discloses a sinking construction device for a cast-in-place underground building, and relates to the technical field of underground building construction. The construction device for the underground building comprises a chain cutter excavating device, a hanging device and a pouring device, the chain cutter excavating device comprises a chain cutter and a chain cutter driving device, and the chain cutter comprises a chain and a cutter installed on the chain; a building is poured on the ground in a segmented mode through the pouring device in the length direction, the chain cutter transversely envelops the outer side of the section of the building. According to the sinking construction device for the cast-in-place underground building, 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, and the chain cutter moving from bottom to top brings the excavated rock soil to the upper portion. 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 for cast-in-place underground buildings. 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. At present, the chain knife is used to excavate the bottom rock and soil, and the overall sinking technical scheme, The sinking construction without hanging device has the following defects because the load of the underground structure itself is too heavy: it is easy to produce inclination deviation, and it is necessary to add a deviation correction device when sinking, and once deviation occurs, it is difficult to achieve deviation correction; such a large The load on the bottom chain knife is pressed on the bottom ch...

[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. At present, the chain knife is used to excavate the bottom rock and soil, and the overall sinking technical scheme, The sinking construction without hanging device has the following defects because the load of the underground structure itself is too heavy: it is easy to produce inclination deviation, and it is necessary to add a deviation correction device when sinking, and once deviation occurs, it is difficult to achieve deviation correction; such a large The load on the bottom chain knife is pressed on the bottom chain knife, resulting in too much power of the driving device, and the chain knife is easily broken; the descending speed is difficult to control; the feed amount of the bottom chain knife is out of control, and the knife is easily damaged; for this reason, we propose A sinking construction device for cast-in-place underground buildings to solve the above problems
