Novel fabricated box culvert and construction method thereof

Abstract

The invention discloses a novel fabricated box culvert and a construction method thereof. The box culvert is mainly composed of an upper box culvert body (1) and a lower box culvert body (2), a plurality of vertical steel bars (3) are arranged in the upper box culvert body (1), and the vertical steel bars (3) extend out of the upper box culvert body (1) in the vertical direction; and a plurality of steel sleeves (4) matched with the vertical steel bars in the upper-layer box culvert are arranged in the lower-layer box culvert (2). Each section of box culvert is divided into the upper layer andthe lower layer, the layers are connected in a sleeve grouting mode, the sleeve grouting technology is different from the prior art, the sleeve is arranged at the top end of the lower component, grouting can be directly performed without special equipment, the connection compactness is guaranteed, and leakage is prevented.

Description

technical field [0001] The invention specifically relates to a novel assembled box culvert and a construction method thereof, belonging to the technical field of assembled buildings. Background technique [0002] Box culverts refer to culverts built with reinforced concrete box-shaped pipe joints; box culverts are generally constructed by cast-in-place, the bottom layer is set in the excavated trench, a layer of concrete cushion is poured, and then the processed steel bars are placed Binding on site, supporting the inner and outer molds, for larger box culverts, the lower half of the bottom plate and side walls are generally poured first, then the upper part of the side walls and the roof reinforcement are bound, the inner and outer molds are supported, and the upper half of the side walls and roof are poured; After the concrete reaches the strength required by the design, the formwork is removed, and the soil is backfilled on both sides of the box culvert at the same time. ...

AI Technical Summary

Problems solved by technology

The cast-in-place box culvert has attracted the attention of the industry due to its low efficiency and high construction difficulty.

[0003] At present, the prefabricated box culvert mainly adopts the form of whole section, which is pre-cast as a section of box culvert; for larger box culverts, in order to meet the hoisting requirements, it is necessary to reduce the length of each section of box culvert, resulting in a large number of box culverts , there are many connection parts, the probability of leakage is high
