Description
Technical Field
The utility model belongs to the radioactive contamination control and the field of cleaing away, what mainly relate to is a decontamination coiled material for concrete medium surface radioactive dust.
Background
At present, with the application and development of nuclear technology, the harm of radioactive pollution to human bodies is gradually paid attention by people, and a large amount of radioactive dust exists in the processes of exploitation, transportation, use and storage of nuclear fuel; nuclear power station accidents, nuclear radiation terrorist attacks and the like are very likely to cause a great deal of radioactive pollution to the environment. The radioactive dust rapidly settles to the ground under the action of gravity, and causes long-term influence and harm to the environment and human bodies.
For the disposal of the radioactive dust on the surface of the concrete medium, methods such as vacuum dust removal, high-pressure water washing, soil shoveling, pressing and decontamination of a strippable film and the like are generally adopted; the vacuum dust removal efficiency is low, the pollution removal operation area is limited, the pollution removal is not thorough, the radioactive dust on the ground can be washed away by a high-pressure flushing method, but a large amount of waste liquid is generated, secondary pollution to the environment is easily caused, the shoveling method is only suitable for relatively flat soil interfaces, hard surfaces such as concrete and the like, the operation is difficult, the decontamination effect of the strippable film pressing decontamination method is obvious, and the film body drying and film forming time is greatly influenced by the environment.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a decontamination plant for controlling and driving concrete road surface radioactive contamination dust, the device can be to the control of the radioactive contamination dust of nuclear accident emergency field area concrete road surface and accident emergency road surface and drive, satisfy opening up of the emergent road in the emergent action process of nuclear accident, make the emergent rescue operation of accident equip with personnel current fast, and simultaneously, the device can be through recovery plant or artifical quick recovery after laying the completion, thoroughly drive subaerial radioactive contamination dust, the needs of the emergent action of specially adapted nuclear accident.
The purpose of the utility model can be realized by adopting the following technical scheme: a decontamination device for controlling and removing radioactive contamination dust on a concrete pavement is formed by compounding a bonding layer, a base material and an anti-bonding layer; the base material is a carrier of a binder, the base material is arranged in the middle, the upper layer of the base material is a bonding layer, the lower layer of the base material is an anti-bonding layer, the bonding layer is mainly a water-based non-setting adhesive, and the anti-bonding layer is coated on the surface of the lower layer of the base material through compaction and bonding.
The base material is glass fiber cloth, has certain tensile strength and surface adhesion effect, and is provided with a laying mode and a laying operation width according to the requirement of nuclear accident emergency action.
The bonding layer is uniformly coated on the upper layer of the base material in a blade coating mode.

FIG. 1 is a schematic diagram of the novel structure of the present application;
in the figure: 1. adhesive layer, 2, substrate, 3, anti-adhesive layer.
Detailed Description
The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings:
as shown in figure 1, a decontamination plant for controlling and driving concrete road surface radioactive contamination dust comprises tie coat 1, substrate 2 and anti-bonding layer 3 complex, substrate 2 be the carrier of binder, the material is glass fiber cloth, has certain tensile strength and surface adhesion effect, the upper strata of substrate 2 sets up to tie coat 1, the lower floor sets up to anti-bonding layer 3, can roll into the coiled material when not using and deposit, sets up laying mode and lays the operation width according to the needs of the emergent action of nuclear accident during the use.
The adhesive layer 2 is mainly a water-based adhesive sticker which is uniformly coated on the upper layer of the substrate 2 and used for adhering radioactive pollution dust, and in practical application, the water-based adhesive sticker can keep a certain adhesion characteristic, has a long storage period and meets the requirements of adsorption and removal of the radioactive pollution dust.
Anti-adhesion layer 3's material be silica gel, have anti-adhesion characteristic, paste on the lower floor surface of substrate 2 through the compaction, mainly used coiled material prevents the adhesion of tie coat 1 with substrate 2 at the laying process, does benefit to the coiled material and lays and open a book the operation.
The utility model discloses a concrete application process does: when the radioactive pollution dust accident occurs on the surface of the concrete medium, according to the characteristics of the ground radioactive pollution dust, firstly determining the laying mode and the laying operation width of the base material 2, rolling the base material 2 into a coiled material, hoisting the coiled material onto a laying mechanism, placing the coiled material in parallel with the ground by using a vehicle-mounted special laying mechanism, then manually pulling the coiled material along the tangential direction, laying the coiled material, and keeping the two sides of the coiled material uniformly stressed in the uncoiling process so as to ensure the flatness of the coiled material; after the uncoiling, the bonding layer 1 is in contact with the concrete ground for compaction, the anti-bonding layer 3 is rolled by a stick of the laying mechanism, so that radioactive pollution dust is firmly bonded on the surface of the bonding layer 1, finally, the coiled material which is bonded and embedded with the radioactive dust particles is stripped from the surface of the medium by utilizing special recovery equipment, the coiled material is curled and packaged by the recovery mechanism into a waste storage compartment of the recovery equipment, the quick cleaning and recovery of the radioactive pollution dust are finished, the secondary pollution is prevented, and the requirement of nuclear accident emergency action is met.
