Problems solved by technology

[0005] At present, there are many oil manufacturers in China, but there are common problems such as grout leakage and large amount of oil in sandy soil or crossing rivers and lakes and other poor soil conditions. For example, the amount of oil in general soil layers is usually 25kg / m (the diameter of the shield machine is about 6.4m), but it may use 70-80kg / m in sandy soil
[0006] However, products imported from abroad, such as those imported from France or Japan, are of good quality and will not cause pollution problems, but they have a problem of high cost: their price is usually twice as expensive as that of domestic shield tail sealing grease, such as the price of imported grease from France, which is 25 yuan / kg, the oil imported from Japan is 34 yuan / kg, and its dosage is not less than that of domestic shield tail sealing grease
[0010] To sum up, in the prior art, there is still no effective solution to the problems of poor sealing performance, large dosage and high cost of shield sealing grease

Abstract

The invention discloses shield tail sealing oil of a shield machine as well as a preparation method and application of the shield tail sealing oil, and solves the problems that the shield tail sealing oil is poor in sealing properties, large in consumption and high in cost. The shield tail sealing oil has the effects of being good in sealing properties, low in consumption and low in cost, and is characterized by consisting of the following components in parts by weight: 14-25 parts of deeply-processed illegal cooking oil, 40-60 parts of filling power, 5-10 parts of a thickening agent, 3-8 parts of fibers, 1-1.5 parts of a mildewproof agent, and 0.5-1.5 parts of a lubricant.

Description

technical field [0001] The invention relates to a shield tail sealing grease of a shield machine, in particular to a shield tail sealing grease of an environmentally friendly recycled raw material, a preparation method and application thereof. [0002] technical background [0003] At present, with the development of domestic infrastructure, subway construction is in full swing, and tunnel shield excavation construction is in the ascendant in large and medium-sized cities in China. After the tunnel construction in the past few years, the construction technology has been greatly improved. In terms of project planning and site selection, due to the needs of urban development, more and more tunnels are deeper than the previous tunnels in terms of buried depth, and there are also more and more tunnels. More and more tunnels will pass through water-rich formations, so a large amount of shield tail seal grease is required for waterproof and lubricated treatment of shield tunneling ...
