Reinforced concrete prefabricated drainage ditch and construction method

Abstract

The invention provides a reinforced concrete prefabricated drainage ditch and a construction method, and belongs to the technical field of building construction. Temporary drainage of different drainage sections within the construction period in a construction site where terraces on the two sides of the drainage ditch have difference of heights is met. A plurality of prefabricated ditch body basicsections are used for being assembled on the construction site to form the prefabricated drainage ditch, the construction quality of the prefabricated drainage ditch can be effectively improved, integrity and stability of the prefabricated drainage ditch can be effectively improved, the overall construction efficiency of a basement with the drainage ditch can be effectively improved, on-site construction is simple and convenient, and the construction period can be effectively shortened. Each of the ditch body basic sections includes an ordinary plate member, a folded plate member, and a non-standard plate member, the non-standard plate member can adjust the elevation of the bottom of the ditch on both sides of the drainage ditch, and thus the application range is expanded.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a reinforced concrete prefabricated drainage ditch and a construction method. Background technique [0002] As an indispensable structure on the construction site, the drainage ditch usually adopts the cast-in-place mode. When constructing the traditional cast-in-place drainage ditch, it often needs to go through multiple processes such as formwork and concrete pouring, which is labor-intensive and time-consuming. The construction quality of the drainage ditch cannot be effectively guaranteed. The cast-in-place drainage ditch after maintenance has many defects, and even problems such as mold swelling and slurry leakage, which seriously affect the service life of the drainage ditch. [0003] Therefore, there is an urgent need for a prefabricated concrete drainage ditch that can meet different drainage cross-sections, have height differences on both sides of the drai...
