Foundation pit steel sheet pile supporting structure without cross brace

Abstract

The utility model relates to the technical field of foundation pit supporting, in particular to a foundation pit steel sheet pile supporting structure without a cross brace, which comprises a plurality of groups of steel sheet pile main bodies, a rectangular supporting cavity is defined by the steel sheet pile main bodies, enclosing purlins are arranged on the steel sheet pile main bodies on two opposite sides of the supporting cavity, and anchor seats are arranged at two ends of the enclosing purlins. An inhaul cable is arranged between the two sets of anchor seats, the two ends of the inhaul cable are connected with the anchor seats respectively, a plurality of sets of bases are arranged on the enclosing purlin at intervals, saddles connected with the inhaul cable in an abutting mode are arranged on the sides, away from the enclosing purlin, of the bases, the jacking mechanisms are arranged on the bases, and the auxiliary mechanisms are arranged on the steel sheet pile body. According to the device, by arranging the enclosing purlins, the inhaul cables and the saddles, the inhaul cables are jacked when the jacking mechanisms jack the saddles, then jacking force is generated by the inhaul cables on the saddles and diffused to the steel sheet pile bodies through the enclosing purlins, stable supporting of a foundation pit is achieved, the occupied space of the whole device is reduced through the structure without cross braces, and the construction efficiency is improved.
