Problems solved by technology

Therefore, the existence of this material has slow setting and hardening and low strength, and there is no technical performance advantage for rapid plugging projects with large water output
At the same time, the waterproof principle of this material restricts its application effect under the conditions of working with water or plugging against water.

Embodiment 1～5

[0027] The specific parts by weight of each raw material in the examples are shown in Table 1.

[0028] Table 1 emergency automatic plugging material embodiment formula

[0029]

[0030] Table 2 shows the main performance index data of Examples 1-5 of the emergency automatic leak plugging material obtained according to the above-mentioned product preparation steps.

[0031] Table 2 Performance of emergency automatic plugging material embodiment

[0032]

[0033] It can be seen from Table 2 that the density of emergency automatic plugging materials with different dosages of floating beads can be changed in a wide range, and the setting time can also be adjusted by the dosage of accelerators. Examples 1-5 of the emergency automatic plugging material have good mechanical properties and impermeability, and the dispersion resistance and fluidity can also meet the requirements.

Abstract

The invention discloses an emergency automatic leaking stoppage material. The material is prepared from sulfoaluminate cement, walnut shell particles, hollow microspheres, bentonite, a dispersion-resisting agent, an expanding agent, a water reducing agent, an accelerating agent and fibers. The emergency leaking stoppage material disclosed by the invention has a quick condensation speed and can automatically move to a water leaking part in water along water flow, so that automatic leaking stoppage under an unmanned operation state is realized; the emergency automatic leaking stoppage material can be used for realizing emergency automatic leaking stoppage of leaking stoppage engineering which is not suitable for manual leaking stoppage construction, such as containers or facilities of high-radioactivity wastewater and toxic and harmful water bodies; influences of wastewater and sewage leak on an ecological environment are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an emergency automatic plugging material. Background technique [0002] At present, the plugging materials used in the project need to clean the surface of the leaking place, gouging, gouging, drilling, twisting, drainage, etc. before construction. During construction, personnel are required to operate or use tools to operate. The post-plugging repair period is long. Moreover, the plugging material needs to be constructed in an anhydrous environment, and it is difficult to condense in water, and it cannot be constructed with water or under pressure. The plugging construction can only be carried out step by step after water is released. This type of plugging material can solve most of the water leakage problems, but for the high-radioactive waste water caused by major natural disasters or major safety accidents, the online, water and pressurized unmanned automatic For...
