For the defect existed in prior art, the purpose of this utility model is to provide a kind of γ-neutron mixing field composite protection structure, realizes effective protection of gamma-rays and neutron in γ-neutron mixing field by this safeguard structure.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of γ-neutron mixing field composite protection structure, comprise steel skeleton, and a side of the nearly radiation field of steel skeleton is provided with for shielding the polyethylene board of neutron, and opposite side is provided with for shielding gamma-ray stereotype.
Further, a kind of γ as above-neutron mixing field composite protection structure, between steel skeleton and stereotype and the outside of stereotype is equipped with fixation steel plate.
Further, a kind of γ as above-neutron mixing field composite protection structure, polyethylene board is schistose texture, between sheet and sheet, adopts seaming to suit mode and is connected.
Further, a kind of γ as above-neutron mixing field composite protection structure, stereotype is schistose texture, between sheet and sheet, adopts seaming to suit mode and is connected.
Further, a kind of γ as above-neutron mixing field composite protection structure, the sheet polyethylene board is of a size of 1m * 2m or 1.24m * 2.5m.

Embodiment
Below in conjunction with Figure of description and embodiment, the utility model is described in further detail.
Fig. 1 shows the structural representation of a kind of γ of the utility model-neutron mixing field composite protection structure, as can be seen from Figure, this meets safeguard structure and comprises steel skeleton 1, one side of steel skeleton is provided with polyethylene board 2, opposite side is provided with stereotype 3, be provided with fixation steel plate 4 between steel skeleton 1 and stereotype 3, the outside of stereotype 3 also is provided with fixation steel plate 4.In order to realize effective shielding of gamma-rays and neutron, in present embodiment, polyethylene board 2 has adopted anti-neutron-Boron-containing-PE plate, stereotype 3 is the anti-gamma-ray stereotype, be aided with fixation steel plate 4 on steel skeleton 1 for supporting construction, nearly radiation field one side of steel skeleton is NEUTRON PROTECTION material-Boron-containing-PE plate fixedly, and opposite side is gamma-rays protective materials-stereotype fixedly.Because the Boron-containing-PE plate can be emitted a small amount of gamma-rays after capturing thermal neutron, the stereotype that is arranged in opposite side can effectively shield gamma-rays.When specific design is calculated, should consider radiation field neutron and gamma-rays environmental dose, protected Boron-containing-PE plate and stereotype type selecting, after the material model is determined, carry out support frame and gib screw type selecting according to weight, thickness, site environment, specifically should be specifically noted that the supplementary protection after screw runs through protective materials fixedly the time.
When carrying out γ-neutron mixing field radiation protection design, for ease of construction, should steel skeleton 1, polyethylene board 2 and stereotype 3 composite protection structures be designed to be convenient to move, constructability, meet the schistose texture of operating mode according to on-the-spot size, the stock size specification is 1 * 2 meter or 1.24 * 2.5 meters, in order to solve the seam crossing leakage problem, between the sheet of polyethylene board of the present utility model and sheet and between the sheet of stereotype and sheet, all adopting seaming to suit mode splices, as shown in Figure 2, seam should guarantee that the either direction ray all has enough shielding thicknesses.
Fig. 3 shows and adopts the utility model γ-field-installed schematic diagram of neutron mixing field composite protection structure, at first according to field working conditions, carrying out required shielding material thickness determines, be polyethylene board and stereotype type selecting, and carry out the steel skeleton material requested according to the weight of selected shielding material and determine, be i.e. channel-section steel and trip bolt type selecting; Then according to the composite structure weight per unit area, in conjunction with field working conditions, carry out the single chip architecture design, seam interlock form design; Last processing and manufacturing, Assembling, can reach γ-neutron mixing field protective shielding purpose.As shown in Figure 3, steel skeleton 1 is installed on existing building 5, a side at steel skeleton 1 arranges installation neutron absorbing layer-polyethylene board 2, opposite side arranges installation gamma shield-stereotype 3, after composite protection structure installs, the outer decorative layer 6 of installing of safeguard structure again, and be fixed by fixing angle steel 7.
