Prefabricated installation construction method for fabricated box culvert

Abstract

The invention discloses an assembly type box culvert prefabrication installation construction method, an assembly type box culvert comprises a plurality of mutually connected box culvert sections and holes at two ends, each box culvert section comprises a top plate, a bottom plate and side walls, two ends of each top plate are respectively spliced with the side walls, the bottoms of the two side walls are in cast-in-place connection, a cast-in-place part is the bottom plate, and a cast-in-place part is connected with the bottom plate; the top plates, the bottom plate and the two side walls form a box-shaped channel, supporting feet protruding outwards are arranged at the bottoms of the side walls, two connectors of the top plates and the side walls are in an elbow shape and are freely hinged, and when different box-shaped culvert sections are connected, the top plates are connected through bent bolts. Prefabrication can be performed in the field in advance, the construction time is greatly shortened, the construction period is shortened, and civilized and green construction is promoted; during excavation construction, the working face is small, and damage and pollution to ground surface underground water and soil are greatly reduced; the quality of the culvert can be effectively improved, the appearance and the percent of pass of a protective layer are greatly improved, and good economic and social benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of box-type culverts, in particular to a prefabricated installation and construction method of prefabricated box-type culverts. Background technique [0002] In recent years, more and more prefabricated concrete box culverts have been used in China. Prefabricated prefabricated box culverts are a kind of reinforced concrete prefabricated box structure, which is a rapid construction process for box culverts. Factory prefabrication, fast production speed and easy control of construction quality, fast mechanical transportation and on-site assembly and construction, can effectively shorten the construction period, and have the advantages of easy control of construction quality, short construction period and high construction efficiency. [0003] However, there are still problems in the construction of box culverts, such as difficult on-site construction quality control, long construction period and high cost. The...

Problems solved by technology

[0003] However, there are still problems in the construction of box culverts such as difficult control of site construction quality, long construction period and high cost. Therefore, in order to solve the above problems, we have designed a prefabricated installation method for prefabricated box culverts.
