METHOD FOR INSTALLING STRUTERS IN SUPPORTING STRUCTURE OF PIT STRENGTHENING SYSTEM AND SYSTEM OF ELEMENTS USED FOR THE PURPOSE OF THIS METHOD Russian patent published in 2022 - IPC E02D17/08 

FIELD: construction.

SUBSTANCE: invention relates to construction, namely to spacers in a retaining structure of an excavation strengthening system and a system of elements. Method for installing spacers in the retaining structure of the excavation strengthening system using a device containing a belt of spacers and expanders. An expander, preferably telescopic, is attached to one end of each strut, thereby forming an extension of the strut. A drawstring device with the possibility of fixing the expansion is attached to the other end of the same strut, also forming an extension of the strut. After measuring the distance between opposite sheet piles and pre-setting the length of the spacers prepared in this way, in accordance with the results of the measurement, the spacers are installed inside the excavation at a given depth so that at the corners of the excavation the ends of the spacers ending with expanders are connected to the ends of the following spacers, ending with clamping devices. Then, after connecting all the struts to each other, preferably using pins, they are pressed against the sheet piles at the corners of the excavation, and the position of the ends of the strut with the expanders attached to them is fixed using tie-down devices attached to the following struts.

EFFECT: ensuring increased safety of the structure, reducing material costs.
