Embodiment Construction

[0043] The following is attached figure 1 The application is described in further detail.

[0044] The embodiment of the application discloses a process and assembly method of a prefabricated box culvert.

[0045] refer to figure 1 , the first aspect, a prefabricated box culvert process, including the following production process:

[0046] Material preparation and mold installation:

[0047] (1) Raw material testing: Sampling and testing the steel bars and cement in batches to determine the quality of the steel bars and cement, thereby improving the quality of the prefabricated box culvert 1;

[0048] (2) Steel bar binding: When binding steel bars in different directions, cross-bound horizontal steel bars and vertical steel bars to form a steel bar skeleton by dismantling the processing method, and ensure that the horizontal steel bars and vertical steel bars are always in a vertical state during the binding process. The reinforced skeleton is convenient to improve the str...

Abstract

The invention relates to a box culvert prefabricating technology and an assembling method, in particular to the technical field of box culvert machining, and the box culvert prefabricating technology comprises the following production technological processes: 1, material preparation and mold installation: (1) raw material detection, (2) steel bar binding, (3) mold installation, and (4) steel bar framework entering into a mold; 2, pouring concrete; and 3, maintaining the box culvert. According to the box culvert prefabricating technology, through material preparation, mold installation, concrete pouring and box culvert maintenance, the box culvert can be conveniently prefabricated in advance, then the construction procedures of on-site construction are reduced, the on-site construction efficiency is improved, and then the construction period of a project is shortened.

Description

technical field [0001] The present application relates to the technical field of box culvert processing, in particular to a prefabricated box culvert process and assembly method. Background technique [0002] Box culverts refer to culverts built with reinforced concrete box-shaped pipe joints. Box culverts are composed of one or more square or rectangular sections. Generally, box culverts are made of reinforced concrete or masonry. Reinforced concrete is widely used. When the span is less than 4m, box culverts are used. For pipe culverts, reinforced concrete box culverts are a cheap substitute. Piers, abutments, and upper and lower slabs are all poured in the same way. [0003] At present, cast-in-place box culverts are generally used. During cast-in-place box culverts, the bottom layer is set in the excavated trench, a layer of concrete cushion is poured on the bottom layer, and the processed steel bars are bound on site. Support the inner and outer molds; for larger box c...
