Comprehensive pipe gallery foundation pit single-face formwork erecting construction method
The invention relates to a single-face formwork erecting construction method for a comprehensive pipe gallery foundation pit, and belongs to the technical field of comprehensive pipe gallery construction. The method comprises the steps that a foundation pit is excavated, pile supporting is carried out, a steel bar frame is additionally arranged between a formwork and a fender post and positioned, the formwork and the steel bar frame are connected together through a formwork drawing assembly, and concrete is poured into the space between the formwork and the steel bar frame. A foundation pit is vertically excavated and supported in a layered mode, the reinforcing steel bar frame is composed of a front row of reinforcing steel bar meshes and a rear row of reinforcing steel bar meshes which are arranged in parallel at intervals, the positioning rods are provided with U-shaped clamping parts which are clamped on vertical main reinforcements and horizontal transverse reinforcements of the reinforcing steel bar meshes respectively, and the die drawing assembly comprises a pull rod, a water stop piece, a conical positioning nut and a locking nut, and the water stop piece, the conical positioning nut and the locking nut are arranged on the pull rod. The front end of the pull rod is hinged to a hook used for being in hooking fit with a horizontal transverse rib close to the fender post, and the pull rod is provided with an external thread section in threaded fit with the conical positioning nut and the locking nut. Compared with a traditional single-side formwork erecting process, materials can be saved, formwork floating and formwork expanding are avoided, and quality is guaranteed.
本发明涉及综合管廊基坑单面支模施工方法，属于综合管廊施工技术领域，包括开挖基坑并进行桩撑支护、在模板与围护桩之间增加钢筋架并对钢筋架进行定位、采用拉模组件将模板与钢筋架连接在一起、在模板与钢筋架之间的空间内浇筑混凝土的步骤；基坑竖向分层开挖并支护，钢筋架由前后两排平行间隔布置的钢筋网组成，定位杆上有分别卡在钢筋网的竖向主筋和水平横筋上的U形卡紧部，拉模组件包括拉杆和设在拉杆上的止水片、锥形定位螺母、锁紧螺母，拉杆的前端铰接有用于与靠近围护桩的水平横筋钩挂配合的挂钩，拉杆上设有与锥形定位螺母和锁紧螺母螺纹配合的外螺纹段。相比于传统单侧支模工艺，本发明能节省材料，避免出现模板上浮、胀模，保证质量。
