Novel double-row pile combined front support supporting structure and construction method thereof
The invention belongs to the technical field of foundation pit engineering, and particularly discloses a novel double-row pile combined front supporting structure which comprises front-row piles, rear-row piles, front supporting piles, umbrella-shaped pull rods, coping beams, crown beams and waist beams, the front-row piles are located on one sides of the rear-row piles, and the top beams are arranged at the tops of the front-row piles and the rear-row piles; the bottoms of the front-row piles and the rear-row piles extend into a bearing soil layer; the umbrella-shaped pull rod comprises a pull rod head, a first hinge, a sliding groove, a tensioning wing, a connecting rod, a second hinge, a rod body, a nut, a third hinge, a connecting main rod and a connecting wedge head, threads matched with the nut are arranged at the end of the rod body, the pull rod head is located at the end, away from the threads, of the rod body, the sliding groove is formed in the inner side of the tensioning wing, and the connecting rod wedge head is slidably connected into the sliding groove. One end of the connecting rod is hinged to the connecting rod wedge head through a second hinge, when the tensioning wing is pulled, the tensioning wing rotates on the head of the pull rod through the first hinge under the action of tension, and meanwhile, the tensioning wing tilts up, so that the tensioning wing is opened.
本发明属于基坑工程技术领域，具体公开了一种新型双排桩组合前撑支护结构，包括前排桩、后排桩、前撑桩、伞状拉杆、压顶梁、冠梁和腰梁，所述前排桩位于后排桩一侧，前排桩和后排桩的顶部均设有冠梁，并且前排桩和后排桩底部均深入持力土层内；所述伞状拉杆包括拉杆头部、第一铰链、滑槽、张拉翼、联系杆、第二铰链、杆体、螺母、第三铰链、联系主杆和联系楔头，杆体端部设有与螺母适配的螺纹，拉杆头部位于杆体远离螺纹的一端，张拉翼内侧设有滑槽，滑槽内滑动连接有联系杆楔头，联系杆一端通过第二铰链铰接在联系杆楔头上，当拉动张拉翼时，张拉翼受到拉力便会通过第一铰链在拉杆头部上转动，同时张拉翼翘起，使得张拉翼张开。
