Abstract
The invention relates to a module shielding method and a structure thereof used for constructing a radial shield room, relating to a radioprotection technique of nuclear technique application field. The structure of the invention is a hollow vertical column module structure with various shapes which is made of steel materials. Joints between vertical columns are embedded mutually to keep radials from shooting out directly from seams. And shielding materials are filled in the vertical columns. Compared with the prior art, the invention has simple installation and low requirement to site installation conditions, and can conveniently and quickly complete construction and reconstruction of the shield room according to the change of source conditions; thus the invention has good economic performance.
Description
Technical field
The present invention relates to the radiation protection technique in Application of Nuclear Technology field, especially build the modular shielding method of beam shielded enclosure.
Background technology
In the Application of Nuclear Technology field, the conventional method step of building beam shielded enclosure is:
1. by Architectural Structure Design, determine the structure of screened room;
2. by the radiation protection design, determine shielding material and the thickness requirement under the source item condition of designing requirement, selected for use;
3. unit in charge of construction finishes the construction work of screened room according to design drawing.If shielding material is a cement, generally be the way that adopts cast-in-site or prefabricated cement plate assembly unit.If shielding material is lead or steel, generally need after becoming large-sized structural parts, factory process carry out on-site consolidation.
There are following two problems in said method in practical operation:
1. consider Eco-power requirement, screened room relates to surplus in the radiation protection design limited.In case the source item condition changes, the thickness of shielding material can't satisfy radiation proof needs, and the reconstruction work of screened room bothers very much;
2. owing to the restriction of execution conditions, large-scale hanging device can't be employed in the working-yard of some screened rooms, and the installation of large-sized structural parts is very difficult.
Above-mentioned source item condition is a special-purpose noun in the radiation protection design, refers to the x-ray apparatus of conductively-closed or some indexs that radioactive source has influence on the radiation protection design, as:
◆ for x-ray apparatus, these indexs comprise ray type, energy, x-ray apparatus output quantity, shield slip, go out bundle mouthful geometric configuration etc.;
◆ for radioactive source, these indexs comprise ray type, energy, radioactive source activity, shield leakage rate, go out bundle mouthful physical dimension etc.
Summary of the invention
In order to overcome above-mentioned problems of the prior art, the purpose of this invention is to provide a kind of modular shielding method of building beam shielded enclosure.Its simple installation, less demanding to on-the-spot mounting condition, can finish the construction reconstruction of screened room quickly and easily according to the change of source item condition, economic performance is good.
In order to reach above-mentioned goal of the invention, technical scheme of the present invention realizes as follows:
A kind of modular shielding method of building beam shielded enclosure the steps include:
1. shield adopts the evacuated mould block structure that steel are made, and can guarantee the scene installation time, lap-joint's phase embedding of each shield prevents that ray from directly penetrating from seam crossing;
2. in the shield, according to the radiation protection designing requirement, fill sand as shielding material, adaptation 9MeV accelerator, output quantity are the source item condition of 3000rad/min-m;
3. adopt difform shield, be overlapped to form between the shieldings that adapt to different on-the-spot uses.
The present invention is owing to adopted above-mentioned method, when the source item condition changing, shield can be taken apart, extract original shielding material out, other assembles can shield after satisfying the shielding material of new radiation protection needs more again, make that the reconstruction work of screened room is convenient, fast, the saving funds.The shield of structure of the present invention, weight and volume are all little, only need simple lifting device just can finish assembling at the construction field (site), greatly reduce the requirement to on-the-spot mounting condition.
The present invention will be further described below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is the synoptic diagram of common structure one of the present invention;
Fig. 2 is the synoptic diagram of common structure two of the present invention;
Fig. 3 is the vertical view of rig-site utilization state of the present invention;
Fig. 4 is that the A of Fig. 3 is to side view.
Embodiment
Referring to Fig. 1 Fig. 2, shield of the present invention is the modular structure of the hollow stud body of the multiple shape made by steel, the rectangle or other arbitrary shape that are shaped as stepped appearance, band dovetail groove that the column body adopts.Lap-joint's phase embedding of each column body is directly penetrated from seam crossing to prevent ray.Be filled with shielding material in each column body, shielding material can be any or an above-mentioned multiple mixtures of material of plumbous sand, iron sand, sand, blinding, polyethylene powders.
When the present invention used, mounting arrangements became screened room as shown in Figure 3, Figure 4.The source item index of this screened room is: 9MeV accelerator, output quantity are 3000rad/min-m.The material of filling in the shield is a sand.The concrete grammar step is:
At first, according to the drawing requirement, design difform employing steel and make a plurality of shields of evacuated mould block structured.And can guarantee on-the-spot the installation time, lap-joint's phase embedding of each shield prevents that ray from directly penetrating from seam crossing.Then, with filling full sand in each shield, finally build up screened room.
Claims (1)
1. a modular shielding method of building beam shielded enclosure the steps include:
