Embodiment Construction

[0026] The construction process of bulk large-diameter steel bellows includes the following steps: foundation pit excavation, site leveling, foundation construction, pre-camber setting, steel bellows assembly, steel bellows joint deviation correction, joint fixation, sealant Treatment, asphalt waterproof layer treatment, backfilling of platform back and eight-character wall construction;

[0027] 1. Measurement and stakeout

[0028] Before pipe culvert construction, the center and vertical and horizontal axes of the pipe culvert should be accurately determined first. And do a good job of pile protection, foundation pit slope slope according to 1:1 for grading.

[0029] 2. Foundation pit excavation

[0030] The method of manual and mechanical excavation is adopted, and the slope of the foundation pit side slope is graded according to 1:1. For places with deep excavation depth and water, the stable side slope should be the main method, and the slope should be properly graded a...

Abstract

A spliced large-diameter steel corrugated pipe construction method includes the following steps of foundation pit excavation, field leveling, foundation construction, pre-camber setting, corrugated pipe splicing, corrugated pipe segment deviation correction, pipe segment fixing, sealing glue treatment, asphalt waterproof layer treatment, stage back backfilling, wingwall building and the like. A steel corrugated pipe has the advantages that deformation adaptability is high, quality control is convenient, construction is convenient, cost for treating foundations and ground foundations is saved, and environment protection is facilitated. As is proved by practice, the steel corrugated pipe is high in tensile strength and can adapt to deformation of the foundations; industrial prefabrication is adopted, so that product quality control is facilitated, and the situation that quality is unstable due to material difference, construction difference, human operation factors and other factors is avoided; installation of a steel structure is not limited by temperature, curing period, environments and time, and the construction period can be effectively shortened; use requirements of a culvert can be met by simply treating the foundations; various materials are greatly saved, resources are saved, and environment protection is facilitated.

Description

technical field [0001] The invention relates to a construction method, in particular to a construction method for large-diameter steel corrugated pipes assembled in bulk. Background technique [0002] The steel bellows structure has the advantages of safety, reliability, economy, technological innovation, convenient construction, and ecological environmental protection. It has achieved good economic and social benefits during construction. However, the traditional bellows has a long construction time, poor foundation treatment, and pipe joints. Easy to crack and cause water seepage. Contents of the invention [0003] The purpose of the invention: to provide a construction method of large-diameter steel corrugated pipes assembled in bulk with rapid construction, quality assurance, no leakage, safety and reliability. [0004] In order to achieve the above object, the present invention takes the following technical solutions: [0005] A construction method for large-diamete...
