by Recently, the Department of housing and urban rural development of Jiangxi Province issued the notice on publishing the list of provincial engineering construction methods in 2021.
The construction method for rapid installation of precast concrete U-shaped cable trench declared by Changjian group was selected as the “provincial construction method of Jiangxi Province in 2021”! The successful selection of the enterprise construction method is not only an affirmation of the scientific and technological innovation ability and technical level of Changjian group, but also provides a strong support for the improvement of our core competitiveness and the shaping of our enterprise brand.
In order to solve the problems of poor forming effect of traditional cable trench construction, bending trend, and many deviation points in plane positioning and elevation positioning of cable trench, our company has introduced the precast assembly construction technology in engineering practice.
Before the excavation of cable trench foundation trench, we first carry out fixed-point marking, and then pour a layer of plain concrete cushion in the excavated cable trench foundation trench, Then, the precast parts, cable supports and cover plates of the cable trench precast by the factory are transported to the construction site, and then the finished products of the cable trench are hoisted in place along the length of the foundation trench by means of mechanical traction and manual assistance.
The levelness is adjusted, and the upper, lower, left and right are aligned.
The joints between the cable trench units are butt jointed in the form of tenon and assembled one by one, The joints shall be subject to multi-stage sealing and waterproof treatment, the cable trench shall be assembled and the cable support shall be installed at the same time, and finally the backfilling and compaction of earthwork, pavement finishing and cover plate installation shall be completed.
The innovation of this technology not only greatly reduces the on-site construction volume and reduces the project cost, but also standardized production by the factory, with high dimensional accuracy, successfully avoids the occurrence of common quality problems such as insufficient strength of cable trench and settlement at the trench edge, and reduces the later maintenance and operation cost.
To grasp innovation is to grasp development, and to seek innovation is to seek the future.
In 2022, Changjian group will always pay attention to the promotion of enterprise construction methods, increase investment in scientific and technological innovation and R & D, timely summarize and refine advanced construction processes and methods, comprehensively improve the construction technology level and scientific and technological content of projects under construction, and add bricks and tiles to the vigorous development of construction industry in our province!
