The invention discloses a multi-row pile foundation pit support structure, which relates to the technical field of foundation pit support, and solves the problem that currently used support structures are mainly assembled for on-site operations, the height is inconvenient to adjust, and different gear rods cannot be flexibly adjusted. Sheltered position, inconvenient to fold and store, lack of quick installation and recycling functions. A multi-row pile foundation pit support structure, including a main support rod; the middle of the main support rod is fixedly provided with a side protection strip and a middle protection strip; the middle of the side protection strip and the middle protection strip is provided with multiple Connecting rods are assembled, and the middle of the side protection bar and the middle protection bar is rotated through the connection structure to provide a hollow shaft frame and a fixed shaft frame; by setting an adjustment device and a bevel gear sleeve, it provides a quick assembly and adjustment function for the support structure. The screw nut can be driven by gear transmission to quickly rotate outside the threaded rod, and the hollow shaft frame and the fixed shaft frame are spread apart by the principle of leverage, and fixed with the fixing nut, which is convenient for assembly and disassembly.
Description
Technical field [0001] The present invention relates to building construction, foundation pit support technology, and is specifically a multi-spanded pile foundation pit support structure. Background technique [0002] Foundation pit support is to ensure the safety of underground structures and the safety of the surrounding environment, the splitting, reinforcement and protection measures used by the foundation pit side wall and the surrounding environment, generally assembled by horizontal longitudinal support structure. The support of the wall. [0003] A patented, for example, patent number CN103074898B discloses a multi-spanded pile of foundation pit support structure, and the outer row stop of the support structure, the medium-sized pile 3 and the inner ribbon pile 2 are used, respectively. The arrangement is arranged in parallel and vertically, and the top of the outer row of soil water stop 1 is provided with a pile top ring beam 4, and all of the outer row piles are conne...
