Subway drainage ditch formwork and construction method

Abstract

The invention provides a subway drainage ditch formwork and a construction method. The formwork comprises a formwork body, a fixed arm, a first adjusting assembly, a first supporting assembly, a swingarm, a second adjusting assembly, a second supporting assembly and a steel rail pressing plate, the formwork body and the fixed arm are both arranged under the swing arm, the formwork body is locatedat the first end of the swing arm, and the fixed arm is located at the second end of the swing arm; the upper end of the first supporting assembly is hinged to the first end of the swing arm, and thelower end of the first supporting assembly is fixed to the formwork body. The upper end of the second supporting assembly is hinged to the middle of the swing arm, and the lower end is fixed to the first end of the fixed arm. The first adjusting assembly is arranged at the first end of the swing arm and used for adjusting the height of the formwork body. The second adjusting assembly is arrangedat the second end of the swing arm and used for adjusting the rotating angle of the formwork body. The steel rail pressing plate is arranged at the second end of the fixing arm. The method has the advantages of being simple in adjustment, high in installation precision, low in construction difficulty and short in construction time.

Description

technical field [0001] The invention relates to the technical field of subway concrete construction, in particular to a template for a subway drainage ditch and a construction method. Background technique [0002] In the construction of urban subway rail transit, the concrete pouring of the subway track bed drainage ditch is an important project in the construction process of the subway construction. The pouring process of drainage ditch concrete is similar to other concrete pouring. First, formwork is made of glue board or steel, and then installed, adjusted, fixed, poured at the construction site, and finally the formwork is removed and turned around. But the existing gutter formwork has disadvantages: [0003] 1. It is cumbersome to adjust and install during construction, especially the construction disadvantages of curved sections are more prominent; [0004] 2. The installation accuracy between the formwork and the formwork is low, and the connection is staggered, and...

Problems solved by technology

[0003] 1. It is cumbersome to adjust and install during construction, especially the construction disadvantages of curved sections are more prominent;

[0004] 2. The installation accuracy between the formwork and the formwork is low, and the connection is staggered, and the slope of the drainage ditch is difficult to control;

[0005] 3. The steel formwork has poor anti-corrosion ability, heavy weight and low turnover efficiency
