Branch pipe assembly type prefabricating installation construction method for building pipeline clamp connection drainage system

Abstract

The invention discloses a branch pipe assembly type prefabricating installation construction method for a building pipeline clamp connection drainage system. The method includes the steps of firstly, prefabrication; secondly, branch pipe system assembly assembling; thirdly, branch pipe system integral hoisting; fourthly, repeating the step three until the branch pipe system integral hoisting of each storey is completed; fifthly, mounting vertical pipes; sixthly, mounting out-roof vent pipes and an underground level main drain. The method has the advantages of no influence of civil engineering secondary masonry progress on project progress, simple construction steps, low construction difficulty, workload reduction, shorter construction period, capabilities of improving construction efficiency and reducing material waste, high practicality and convenience in popularization and use.

Description

technical field [0001] The invention belongs to the technical field of construction of water supply and drainage systems in buildings, and in particular relates to a construction method for pre-installing a combination of branch pipes of a building pipeline connected to a drainage system. Background technique [0002] At present, in the construction process of the building drainage system, the construction sequence of installing the vertical riser first and then installing the branch pipe system is usually adopted. The pipeline interface usually adopts the adhesive interface connection, the wire connection connection and the hot melt connection. The main defects of the traditional method are as follows: [0003] 1. In the traditional installation sequence of drainage pipes, the progress of the project is affected by the progress of the secondary masonry of civil construction, which increases the difficulty of project progress and cost control. [0004] 2. The branch pipe sys...

AI Technical Summary

Problems solved by technology

[0003] 1. The traditional installation sequence of drainage pipes, the progress of the project is affected by the progress of the secondary masonry of the civil construction, which increases the difficulty of project progress and cost control

[0004] 2. The branch pipe system adopts on-site measurement and manual cutting, which has a large workload and a long construction period, and is not conducive to the system management of pipe materials. It is difficult to pre-allocate materials in the system, and the material waste is large

[0005] 3. All operations in traditional construction are high-altitude operations, with heavy workload, difficult construction, low work efficiency and long construction period
