Problems solved by technology

FRP pipes are especially suitable for water supply projects because of their light weight, high strength, easy installation, long service life, no toxic side effects, corrosion resistance, and no scaling. Its light weight and high strength greatly reduce construction difficulty and greatly improve work efficiency. However, due to improper installation methods, various failures and problems occurred during use

Embodiment Construction

[0009] The technical solution of the present invention will be described in detail below.

[0010] The invention provides a method for installing a sand-filled FRP pipeline, which includes the following steps: before installing the pipeline, lay a 100-150 mm thick sand layer to ensure that the axils of the pipe are fully filled, and the sand-filled FRP pipe is light in weight and can be artificially Lower the pipe and use a chain hoist for socket connection. Before connecting, the sealing grooves at both ends of the pipe should be filled with lubricating oil, and the O-shaped rubber sealing ring should also be coated with butter to ensure smooth and light socket connection and prevent strain. Pipe wall or sealing ring; after the pipeline is installed qualified, spread sand 250-300 mm on both sides of the pipeline along the direction of the pipeline, compact the axils of the pipeline, and then pave in layers; backfill both sides of the pipeline with medium-coarse sand, The thic...

Abstract

The present invention disclosed a method of installation of sand -holding glass fiber reinforced pipelines. Before the pipeline is installed, it should be paved with 100-150mm thick sand layer to ensure that the axillary is filled with full.Hand -pinchants are connected. Before connecting, you should apply lubricating oil in the sealing slot on both ends of the tube. The O -type rubber sealing ring should also be applied with butter to ensure that the inheritance connection is smooth and light.Circle; after passing the pipeline installation, first spread 250-300 mm along the direction of the pipeline on both sides of the pipeline, pound the tube armpit, and then lay layers.It is greater than 20cm and the density is 95%; the backfill operation above the top of the tube is performed; and then the lust ash is used to add 3%~ 5%curing agent to lay layered paving and fully vibrate.

Description

technical field [0001] The invention relates to the technical field of drainage pipeline installation, in particular to a method for installing a sand-filled glass fiber reinforced plastic pipeline. Background technique [0002] For a long time, in the design and construction of drainage engineering, most of the outdoor drainage pipes use reinforced concrete drainage pipes. This is mainly because the manufacturing process of reinforced concrete pipes is primitive and simple, and the price is low. [0003] However, reinforced concrete pipes have many disadvantages. FRP pipe is especially suitable for application in water supply projects because of its light weight, high strength, convenient installation, long service life, no toxic side effects, corrosion resistance, and no scaling. Its light weight and high strength greatly reduce construction difficulty and greatly improve work efficiency. However, due to improper installation methods, various failures and problems occurr...
