Pipeline spraying repair material, preparation method and construction process for repairing pipeline with pipeline spraying repair material

Abstract

The invention discloses a pipeline spraying repair material, a preparation method and a construction process for repairing a pipeline with the pipeline spraying repair material. The repair material isprepared from the following raw materials in parts by weight: 40 to 60 parts of binding material, 45 to 70 parts of aggregate, 3 to 9 parts of dispersible latex powder, 3 to 10 parts of fiber material, 2 to 6 parts of water-retaining agent, 1 to 3.5 parts of accelerator, 2 to 6 parts of underwater curing agent, 0.4 to 1.2 parts of water reducer, 2 to 6 parts of stabilizer and 25 to 35 parts of water. The construction process can be implemented in a moist environment or a water containing environment, so that the engineering cost in pipeline repair is lowered greatly. The pipeline spraying repair material can still be used in the presence of water in the pipeline, so that the environment interference is low. The repair operation can be finished in a non-digging repair way in the construction process, so that the maintenance cost is lowered, and other barriers can be avoided. The problem of leakage of underground pipelines can be solved efficiently without causing traffic jam. The repair construction result is satisfactory, the repaired pipeline has the advantages of uniform surface thickness, smoothness, flatness, seepage resistance, high corrosion resistance, and practical runningof the underground pipelines can be satisfied.

Description

technical field [0001] The invention relates to the field of spraying mortar, in particular to a pipeline spraying repair material, a preparation method and a construction process for using the material for pipeline repair. Background technique [0002] The urban drainage system is an important link in the urban rainwater drainage, water pollution control and water ecological environment protection system, and an important infrastructure to ensure the survival and sustainable development of the city. The pipeline system plays a vital role in the lives of urban residents, bringing great convenience to the lives of residents, and it is also an important infrastructure that is indispensable for urban development. With the rapid development of my country's economy and the advancement of urbanization, the number and length of buried pipelines have also increased rapidly over time. [0003] The drainage pipe network is the "urban vein", which undertakes the tasks of urban sewage ...
