Foundation pit steel trestle structure and construction method thereof
The invention discloses a foundation pit steel trestle structure and a construction method thereof. The foundation pit steel trestle structure comprises three trestle beams, and blocking ridges are formed on the opposite sides of the beam faces of the two outer trestle beams; a through groove is formed in the bottom of the riding beam support, the top of the other middle trestle beam is arranged in the through groove in a sliding mode, a locking piece is installed in the through groove, notches facing the outer side trestle beam are formed in the two opposite sides of the riding beam support, the bottom walls of the notches are flush with the beam face of the outer side trestle beam, and locking rods are installed on the side walls of the notches. One end of the steel bridge deck slab is embedded in the notch, a lock hole is formed in one end of the steel bridge deck slab, the lock rod is detachably inserted in the lock hole, the other end of the steel bridge deck slab is in lap joint with the beam face of the outer side trestle beam, and a compensation groove is formed between the other end of the steel bridge deck slab and the blocking ridge and between the other end of the steel bridge deck slab and the beam face of the outer side trestle beam; and the post-pouring concrete is poured in the compensation groove. The problems that the construction precision of the concrete trestle beam is insufficient, and the distance between the trestle beams is not matched with the length of the steel trestle panel, so that the steel trestle panel cannot be lapped are solved.
本发明公开了一种基坑钢栈桥结构及其施工方法，包括：三栈桥梁，两外侧栈桥梁的梁面的相背侧形成有挡坎；骑梁支座，骑梁支座的底部形成有通槽，另一中间栈桥梁的顶部滑设于通槽中，通槽中安装有锁定件，骑梁支座的相对两侧形成有朝向外侧栈桥梁的缺口，缺口的底壁与外侧栈桥梁的梁面齐平，缺口的侧壁安装有锁杆；钢桥面板，其一端嵌设于缺口中，钢桥面板的一端开设有锁孔，锁杆可拆卸地插设于锁孔中，钢桥面板的另一端搭接于外侧栈桥梁的梁面，钢桥面板的另一端与挡坎、外侧栈桥梁的梁面之间形成补偿槽；后浇混凝土，浇筑于补偿槽中。本发明解决了混凝土栈桥梁施工精度不足，栈桥梁间距与钢栈桥面板的长度不匹配，导致钢栈桥面板无法搭接的问题。
