The invention relates to the technical field of foundation pit supporting devices, in particular to a deep foundation pit covered-excavation construction main structure supporting device which comprises a control column, wherein two supporting columns are correspondingly arranged at two ends of the control column; one end of each supporting column extends to a corresponding columnar slots formed on the bottom surface of the control column; a plurality of uniformly-distributed jamming units are arranged around the supporting columns in an encircling manner; the jamming units are arranged in thecontrol column; a plurality of uniformly-distributed collecting-distributing tube cavities I and collecting-distributing tube cavities II are formed on the control column in an encircling manner; anda three-way tube cavity is formed at the middle position of the control column. According to the structural design of the deep foundation pit covered-excavation construction main structure supportingdevice, the convenient telescopic adjustment of the supporting columns on the control column can be achieved; during air injection into the three-way tube cavity, whether the external exhaust ports of the collecting-distributing tube cavities I and the collecting-distributing tube cavities II are blocked or not can be controlled just by rotating a sealing ring I and a sealing ring II; and consequently, the quick removal or placement of the entire supporting device from or in the clearance between two foundation pit vertical plates can be facilitated.
Description
technical field [0001] The invention relates to the technical field of support devices for foundation pits, in particular to a support device for the main structure of deep foundation pit cover and excavation construction. Background technique [0002] The foundation pit support device in the prior art is simple in structure and single in function, and cannot well meet the actual needs in the construction process of deep foundation pit cover and excavation. There is a certain dependence on the characteristics, and the installation or removal of the support device will affect the construction progress. [0003] If a support device can be invented that has a stable and efficient support function and is conveniently fixedly installed in the foundation pit, the problem can be solved. For this reason, we provide a support device for the main structure of the deep foundation pit cover and excavation construction. Contents of the invention [0004] The object of the present inve...
