Cement component crossing highway and mounting method

Abstract

The inventio discloses a cement component crossing a highway and a mounting method and belongs to the field of road construction. At present, when a traditional cast-in-place manner is adopted for construction, the construction process is tedious, the construction plant requirement is high, the construction period is laggard, and the maintenance cost is high. The cement component crossing the highway comprises a fabricated box culvert (1), and a convex inserting groove (2) is machined in an end opening of a top mold of the fabricated box culvert; a convex clamping groove (3) with an annular gap is machined in a bottom end opening of the fabricated box culvert, and the convex clamping groove is inserted into the convex inserting groove in another fabricated box culvert; PE pipes (4) for forming prestressed tendon pore ducts are arranged at the four corners of the convex inserting groove, the PE pipes are linearly buried in the four corners of the upper portion of the fabricated box culvert, and then pore ducts (5) are preserved in the four corners of the pipe joints of the PE pipes; steel strands penetrate through the pore ducts, tensioning is carried out, and joint treatment and pore duct grouting are carried out after tensioning is completed; and then wing wall treatment and culvert side backfilling are carried out.

Description

Technical field:

[0001] The invention relates to a cement component and an installation method for crossing a road. Background technique:

[0002] The original design plan adopts the cast-in-place construction method. When the pour-in-place method is used for construction, the construction process is cumbersome, the construction site requirements are high, the construction period is delayed, and the maintenance cost is high. Construction needs to be carried out while it is open to traffic, and there are many culverts in this road section, with an average extension of 150 meters, which requires a large working surface. The travel of the villagers has brought great inconvenience. After investigation, the local villagers use motorcycles to travel a lot, and they often carry goods and people. According to the past construction experience of cast-in-place culverts, villagers sometimes fall into the pit because they are not familiar with the conditions of the construction access ...
