Abstract

The invention relates to the technical field of bridge culvert construction and provides a box culvert basic leveling construction method. The box culvert basic leveling construction method comprisesthe following steps: pouring a plurality of leveling layers arranged in parallel; completing box culvert assembling on the leveling layers, wherein the length direction of the leveling layers is consistent with that of the box culvert, and the box culvert is provided with a plurality of grouting holes along the length direction; and a filling layer is poured in the gap of the grouting holes between the adjacent two leveling layers. By the box culvert basic leveling construction method, the problem in the prior art that the stress at the bottom of the box culvert is concentrated by low assembling precision of the box culvert caused by unflatness of a foundation pad layer is solved.

Description

technical field [0001] The invention relates to the technical field of bridge and culvert construction, in particular to a construction method for leveling a box culvert foundation. Background technique [0002] Box culverts refer to culverts built with reinforced concrete box-shaped pipe joints. Box culverts consist of one or more square or rectangular sections, generally made of reinforced concrete or masonry, but reinforced concrete is widely used. [0003] In the process of highway construction, box culverts are often used. Box culverts are generally constructed in a prefabricated manner. The box culverts can only be assembled after the construction of the foundation cushion of the box culvert. The unevenness of the foundation cushion will directly affect the quality of the box culvert. Assembly accuracy may also cause stress concentration at the bottom of the box culvert. Contents of the invention [0004] (1) Technical problems to be solved [0005] In view of the...
