Problems solved by technology

Traditional cable trench construction mainly uses wooden formwork and small combined steel formwork for segmental construction. The construction process includes formwork assembly, reinforcement, concrete pouring, formwork disassembly, transition, cleaning and oiling, etc., which is time-consuming and labor-intensive, and the construction cost of the formwork project High, complicated process, long cycle time, many reinforcement supports, poor integrity, difficult to control the flatness of the top surface, easy to leak water at the joint, difficult to control the appearance quality, and the civilized image of the working surface is not good

Abstract

The invention belongs to the technical field of cable trench construction, and particularly relates to a movable formwork structure and a construction method thereof. The construction method comprisesthe steps of formwork system machining and manufacturing, construction preparation, contact surface treatment, drainage blind pipe mounting, steel bar binding and mounting, formwork moving and positioning, pipe burying piece mounting and fixing, formwork overall reinforcing and plugging, one-time overall pouring and coagulation, maintenance and formwork dismounting and formwork moving to enter the next construction section. The construction method is simple and convenient to operate, good in quality, high in construction speed, high in efficiency, low in labor intensity, time-saving, labor-saving, low in comprehensive construction cost, good in economic benefit and suitable for construction of trench structures such as tunnel cable trenches and roadbed drainage ditches.

Description

technical field [0001] The invention belongs to the technical field of cable trench construction, in particular to a mobile formwork structure and a construction method thereof. Background technique [0002] Cable trenches are important construction projects for substations and switch stations in the power grid system, and are often built in infrastructure such as tunnels. The construction quality of the cable trench is related to the operation quality of the cable line and the service life of the line equipment. Its sustainability is very important. Therefore, the construction technology of cable trenches has been paid more and more attention. Traditional cable trench construction mainly uses wooden formwork and small combined steel formwork for segmental construction. The construction process includes formwork assembly, reinforcement, concrete pouring, formwork disassembly, transition, cleaning and oiling, etc., which is time-consuming and labor-intensive, and the construc...
