A support device for the main structure of deep foundation pit cover and excavation construction

Abstract

The invention relates to the technical field of foundation pit support devices, in particular to a support device for the main body structure of deep foundation pit cover and excavation construction, including control columns, two ends of the control columns are respectively provided with a support column, and one end of the support column extends to the bottom surface of the control column In the opened columnar groove, a number of evenly distributed clamping units are provided around the support column, and the clamping units are arranged in the control column, and a number of evenly distributed collecting and distributing lumens and collecting and distributing lumens are arranged on the upper ring of the control column. There is a three-way lumen in the middle of the control column. The structure design of the present invention realizes the convenient telescopic adjustment of the support column on the control column. While injecting gas into the three-way lumen, only need to rotate the first sealing ring and the second sealing ring, By controlling whether the outer exhaust outlets of the first and second collection and distribution tubes are blocked, the stable control of several clamping units can be realized, which is convenient for the entire support device to be quickly removed from between the two foundation pit vertical plates or placed.

Description

Technical field [0001] Technical Field The present invention relates to a foundation supporting means, in particular to a deep foundation construction excavation structural support for the cover apparatus main body. Background technique [0002] Foundation supporting device structure is simple prior art, single function, can not meet the actual needs of deep foundation pit excavation during construction of the lid, the lid deep foundation pit excavation during construction and easy installation of the foundation supporting the shutter means there are certain characteristics of dependence, or taken out of the mounting support means will impact on the construction schedule. [0003] If able to invent a stable and efficient support device having a support function, and easy fixedly mounted in the pit, can solve the problem, we provide a construction for this structure support body a dark excavation pit cover. Inventive content [0004] Object of the present invention is to provide ...
