Description

Technical Field

[0001] The present invention relates to a modular construction device, and particularly to a modular construction device for transmission line foundations. The present invention belongs to the field of construction of power line foundations. Background Art

[0002] In the construction of transmission line projects, the terrain through which the lines pass is complex, mostly mountain forests, hills, swamps and farmlands. The construction period is tight and the effective construction period is short. The foundation construction of transmission lines is a very important construction link in the three stages of line construction foundation, tower erection, and conductor and ground wire stringing construction. The foundation construction of the line has a long construction and maintenance period. It takes 28 days for concrete pouring and maintenance. Because the number of line foundations is large, they are linearly distributed and widely distributed across regions. Usually, multiple construction teams carry out construction simultaneously, and the construction personnel have uneven levels. The construction sites are scattered, and it is relatively difficult to control the foundation safety and quality at the construction sites. In the traditional foundation construction method, the construction personnel often step on the fixed part of the foundation formwork during on-site construction, and it is difficult to control the key index data such as the foundation diagonal and the root opening. The above-mentioned characteristics of foundation construction seriously restrict the important indicators such as the construction safety, quality, and progress of the line foundation project, and cannot meet the management requirements of power grid infrastructure construction. Developing a safe, stable, economical, reliable, and standardized modular special mold system for transmission line foundations has become a new topic in the research of power line foundation construction.

[0003] At present, the traditional line foundation construction usually adopts two methods: large-scale foundation excavation and split-leg foundation excavation. The traditional methods have the following disadvantages:

[0004] In the traditional construction mode, wooden (bamboo) formwork is used for concrete pouring. Restricted by materials and on-site processes, the quality, specifications, and dimensions of the concrete formwork are not uniform, which is not conducive to quality control; the strength of the formwork is average, and problems such as "formwork bulge" and "formwork shrinkage" are likely to occur; and it does not meet the requirements of "green" construction. In the traditional construction mode, the formwork is usually fixed using "locking-type" scaffolding components combined with scaffolding steel pipes. There is no "professional safety construction platform" at the construction site. Most of the concrete placing, concrete vibration, and control of key quality data by construction personnel rely on the "locking-type" scaffolding fixing device, which affects the quality control of foundation construction. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems that the quality, specifications, and dimensions of traditional line foundation construction are not uniform, which is not conducive to quality control; it is easy to have problems such as formwork bulge or formwork shrinkage, and the use of locking-type scaffolding for fixation affects the quality control of foundation construction, and then provide a modular construction device for transmission line foundations.
