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 underground building comprises an outer wall, a top plate, a bottom plate and a construction device, and is composed of end sections located at the two ends and a middle section located in the middle, and each end section comprises a transverse wall located at the end and two longitudinal walls located on the two sides; the construction device comprises an excavating device, a hanging device located at the top of the building and a pouring device, and the excavating device excavates rock soil at the bottom of the bottom plate and comprises a chain cutter and a driving device; the driving device is mounted above the bottom plate; and each longitudinal wall comprises vertically staggered holes located above the bottom plate, and the chain cutter envelops the bottom plate through the holes. The building is poured on the ground in a segmented mode through the pouring device in the length direction, the building is in a suspended state through the hanging device, the driving device is started, the chain cutter at the bottom of the bottom plate excavates rock soil, and the excavated rock soil is brought to the upper part by the chain cutter running from bottom to top, so that the sinking operation of the building is realized.

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
