Prestressed trapezoidal modular arch culvert and construction method thereof

Abstract

The invention discloses a prestressed trapezoidal modular arch culvert and a construction method thereof. The arch culvert comprises a plurality of prefabricated bases with tenons, a plurality of prefabricated side walls, a plurality of prefabricated top arch modules and a plurality of prefabricated inclined arch modules, wherein the multiple prefabricated bases with tenons are arranged in two parallel rows, the multiple prefabricated side walls are installed on each row of prefabricated bases with tenons, and the prefabricated side walls are vertically arranged; the multiple prefabricated inclined arch modules are arranged in two rows, and the bottom parts of the two rows of prefabricated inclined arch modules are supported at the upper ends of the two rows of prefabricated side walls correspondingly; the multiple prefabricated top arch modules are arranged in a row; the two sides of the row of prefabricated top arch modules are supported on the top parts of the two rows of prefabricated inclined arch modules correspondingly; and prestressed holes are formed in the prefabricated side walls, the prefabricated inclined arch modules and the prefabricated top arch modules, the corresponding prestressed holes in the prefabricated side walls, the prefabricated inclined arch modules and the prefabricated top arch modules are communicated, and prestressed tendons penetrate through the prestressed holes, are tensioned and then are anchored. The arch culvert is simple in structure and convenient to construct, and the construction cost of the arch culvert is reduced; and the integrity of the fabricated culvert is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of culvert construction, and in particular relates to a prestressed trapezoidal modular arch culvert and a construction method thereof. Background technique [0002] In recent years, my country's infrastructure has developed rapidly. The length of roads and bridges is increasing year by year, the demand for culverts is increasing, and the requirements for culverts are getting higher and higher. Existing culverts are roughly divided into two types: a kind of cast-in-place type, and a kind of assembled type. [0003] The existing prefabricated arch culverts generally have the following deficiencies: (1) The self-weight of the components is relatively large. (2) Poor structural integrity. (3) The construction process is complicated. (4) The degree of standardization is low. Contents of the invention [0004] In order to solve the above technical problems, the present invention provides a prestressed trap...
