Problems solved by technology

For pipes larger than 1200mm, it is difficult to realize the processing, transportation, welding and U-shape of HDPE pipes, so the risk of success in repairing large pipes increases, and the cost of implementation also increases sharply

Embodiment Construction

[0028] The method for repairing large pipes or ditches with plastic plates perfused with resin linings according to the present invention will be described in conjunction with the accompanying drawings and embodiments.

[0029] The technical idea of ​​the method for repairing large pipes or ditches with nailed plastic boards perfused with resin lining is based on the advantages that large-diameter pipes can enter the construction personnel and the characteristics of the existing technology, such as various anti-seepage plastic boards and various resins Sealing and anti-corrosion and other characteristics, this method was obtained after repeated research.

[0030] The core of the present invention is firstly to combine plastic boards with a certain height and a certain thickness into a special lining plastic board. The gap between the boards is filled with a special room temperature curing resin. After the resin is injected into the gap, a certain pressure is maintained, and i...

Abstract

The invention provides a method for restoring the lining of a large pipeline or ditch by pouring resin on a nail-embedded plastic plate, which comprises the following steps of: cleaning the restored large pipeline or ditch; manufacturing the nail-embedded plastic plate according to the size of the large pipeline or ditch; pre-burying expansion nails; installing the nail-embedded plastic plate; blending naturally cured resin; pouring materials; and carrying out port processing and inspection. The invention has the effect that the resin used in the method is crosslinked into an organic whole after cured and has long corrosion-resistant service life, the used lining plastic plate has the characteristic of corrosion resistance, small frictional resistance, long service life and conformity to drinking water, and the method is suitable for the restoration of large-caliber water supply and drainage pipelines and the corrosion resistance and seepage resistance of large-size ditches. In consideration of pavement excavation compensation, building facility removal compensation and the like, the cost of excavation and pipe replacement is generally 1.5-3 times of that of non-excavation and restoration or reinforcement. A non-excavation mode is adopted by the invention, and the restoring method by pouring the resin on the nail-embedded plastic plate solves the difficult problems of restoration of large pipelines and corrosion resistance and seepage resistance of underground buildings.

Description

technical field [0001] The invention relates to an overall repair and anti-seepage and anti-corrosion technology for pipelines and ditches, in particular to a method for repairing large pipelines or ditches with nailed plastic plates poured into resin linings. Background technique [0002] At present, there are usually two methods for repairing the overall pipeline lining of the pipeline, namely, the inverted lining (CIPP) and the interspersed high-density polyethylene pipe (U-HDPE). Among them, the inverted lining (CIPP) technology is usually suitable for pipelines with a diameter of 1200mm or less due to its many technical parameters, complex processes, and high construction risks. Boiler heating is required for the subsequent curing process. Once a certain link is not strictly controlled, it is easy to cause the entire pipe section to be scrapped. [0003] Another technology, interspersed with high-density polyethylene pipe (U-HDPE), is generally suitable for pipes that...
