Suspended formwork construction method for seascape trestle

Abstract

The invention discloses a suspended formwork construction method for a seascape trestle, and belongs to the technical field of suspended construction of seascape trestles. The method comprises the following steps in order: 1, paying off according to a support construction drawing; 2, driving a cast-in-place concrete-filled steel tube pile; 3, manufacturing a steel hoop mold; 4, hoisting the steelhoop mold and mounting the steep hoop mold to the pile, and screwing down split bolts; 5, laying main beam I-shaped steel one by one; 6, mounting secondary beam I-shaped steel, and firmly welding withthe main beam I-shaped steel; 7, sequentially laying battens and installing plywood; 8, pre-pressing, binding reinforcing steel bars, installing side molds, pouring and tamping concrete, and maintaining; 9, hooking out and hoisting the secondary beam I-shaped steel, hooking out and hoisting the main beam I-shaped steel, prying off a bottom mold, and fishing away; and 10, dismounting steel ropes,loosening the bolts, dismounting the hoop device, and performing acceptance check. A scaffold erecting problem of a shallow sea near-beach section can be solved, beam plate concrete pouring and tamping stability is effectively guaranteed, economic benefits and safety are improved, the material loss rate is reduced, and the green construction requirement is also met.

Description

technical field [0001] The invention relates to the technical field of suspended construction of sea view trestle bridges, in particular to a construction method of suspended formwork for sea view trestle bridges. Background technique [0002] With the development of the economy, shallow seas, wetlands, lakes, rivers and other scenic areas have become places for residents and tourists to view the scenery. The demand for trestles and viewing platforms built on offshore shoals, rivers, lakes, and wetlands has been increasing. In the construction of traditional trestle bridges, the method of erecting the floor frame support system is generally adopted. This method has mature erection technology and is easy to operate. However, in the shallow sea near the beach and marsh areas, the geological conditions are complex, and the landing frame is easily eroded by sea water and typhoons. At the same time, due to the soft soil, it is easy to cause the vertical pole to sink, resulting in...

AI Technical Summary

Problems solved by technology

However, in the shallow sea near the beach and marsh, the geological conditions are complex, and the floor frame is easily eroded by sea water and typhoon. At the same time, due to the soft soil, it is easy to cause the vertical pole to sink, resulting in uneven settlement of the concrete components, which affects the quality of the project.

At the same time, due to the underwater operation, it is not easy to dismantle the steel pipe of the landing frame, and the material loss rate is extremely high. Therefore, we propose a construction method for the suspended formwork of the sea view trestle bridge
