Embodiment 1

[0045] This embodiment provides a kind of filler for processing scrap pipelines, by weight, the filler includes:

[0046] 100 parts of water, 100 parts of activated sludge, 50 parts of cement, 20 parts of fly ash, 10 parts of lime, 1 part of thickener, 5 parts of foaming agent and 2 parts of retarder.

[0047] The harmless treatment method for waste pipes using the above fillers:

[0048] Holes are opened at both ends of the pipe, one end is the grouting hole and the other end is the air outlet. The filler provided in this embodiment is injected into the pipeline through the grouting hole, and the grouting at the other end starts to emerge and then stops grouting. Close the grouting port and air outlet.

[0049] The volume occupied by the filler in the scrapped pipeline is 98% of the inner volume of the scrapped pipeline.

Embodiment 2

[0051] This embodiment provides a filler for treating scrap pipelines and a harmless treatment method, which is roughly the same as that of Embodiment 1, except that the parameters in the filler are different, and the differences are as follows.

[0052] In parts by weight, the filling includes:

[0053] 100 parts of water, 80 parts of activated sludge, 30 parts of cement, 40 parts of bentonite, 10 parts of lime, 4 parts of thickener, 2 parts of foaming agent and 1 part of retarder.

Embodiment 3

[0055] This embodiment provides a filler for treating scrap pipelines and a harmless treatment method, which is roughly the same as that of Embodiment 1, except that the proportion of components in the filler is different, and the difference is as follows.

[0056] In parts by weight, the filling includes:

[0057] 100 parts of water, 40 parts of activated sludge, 50 parts of cement, 20 parts of fly ash, 30% of bentonite, 10 parts of lime, 1 part of thickener and 2 parts of retarder.

[0058] The harmless treatment method for waste pipes using the above fillers:

[0059]The filler occupies 96% of the internal volume of the discarded pipeline in the scrapped pipeline.

Abstract

The invention discloses a filler for processing a junked pipeline and a harmless treatment method for the junked pipeline, and relates to the technical field of junked pipeline processing. Specifically, the filler is prepared from the materials in parts: 10-100 parts of activated sludge, 20-50 parts of cement and 5-50 parts of solid matrix. According to the embodiments of the filler and the harmless treatment method, the junked pipeline is filled by using the filler rich in organic matters, soil fertility is not affected, after the pipeline is solidified, the compressive strength is higher than the soil compressive strength and lower than the compressive strength of existing solidified slurry, the size is not shrunk, no ground collapse appears, and the stability of ground surface bearing materials is not affected.

Description

technical field [0001] The invention relates to the technical field of waste pipeline treatment, in particular to a filler used for treating waste pipelines and a harmless treatment method for waste pipelines. Background technique [0002] The underground pipe network of pipelines has complex purposes, and it undertakes the transportation function of various fluids such as water, heat, gas, and oil. After the completion of metal pipelines, with the expansion of the scope of human activities, the environment around many pipelines and the use of land have undergone drastic changes. Some scrapped pipelines have been unable to be dismantled due to factors such as economy, safety and environmental protection, such as agricultural land and forest land. Land occupation, adjacent to industrial, commercial and civil facilities, road traffic occupation and other areas. [0003] Discarded pipes are usually disposed of by dismantling them if they can be dismantled, those that cannot be...
