Hydraulic die plate system of precast box culvert and use method thereof

Abstract

The invention discloses a hydraulic die plate system of a precast box culvert. The hydraulic die plate system comprises a base, a bottom die, an outer die, an inner die, a sliding rail system, a hydraulic system and a locating system, wherein the bottom die is enclosed by the inner die and the outer die, forming a box culvert die plate of a box type structure, and die disassembly and die assemblyare realized by driving the inner die and the outer die through the hydraulic system; the base is fixed to a ground embedded component through welding, and the bottom die is mounted above the base through welding; a central bracket is arranged in the center of the base, and hydraulic cylinder lug plates used for mounting a hydraulic cylinder are welded both below the base and on the central bracket; and the periphery of the bottom die is provided with grooves used for arranging rubber strips. The invention further discloses a use method of the hydraulic die plate system of the precast box culvert. As the box culvert die plate of the box type structure is formed by enclosing the bottom die by the inner die and the outer die, the splicing seams of the die plate are greatly reduced, and the appearance quality of the precast box culvert can be greatly improved; and die disassembly and die assembly are realized by driving the inner die and the outer die through the hydraulic system, so thatthe production efficiency can be greatly increased.

Description

technical field [0001] The invention relates to a prefabricated box culvert hydraulic formwork system and its application method. Background technique [0002] Prefabricated box culvert, also known as assembled box culvert, is a prefabricated reinforced concrete box-shaped structure. It is a rapid construction process for box culverts. It has the characteristics of factory prefabricated processing and on-site assembly. It is mainly used for projects that require a short construction period. project. Generally, box culverts are constructed by using on-site binding of steel bars, supporting formwork, and pouring concrete. The construction period is long, and for projects with short construction period requirements, the use of prefabricated box culverts can greatly shorten the construction period. [0003] At present, domestic prefabricated box culverts have been widely used in various fields, and their quality requirements have gradually increased. In the production process o...

Problems solved by technology

[0005] The purpose of this invention is to solve the technical problems that there are many splicing joints in the formwork of box culverts, which is prone to slurry leakage, and at the same time adopts gantry crane or manpower to remove the formwork, the efficiency of mold closing is low, and it is not easy to formwork positioning and size adjustment
